    This paper introduces the environmental issues (both real and perceived) associated with uranium exploration, mining, milling, and tailings management. As well, some of the issues pertaining to the closeout of uranium tailings areas are discussed. These issues have received considerable attention in Canada in public inquiries and hearings that have been held across the country. The major conclusions of some of these hearings are also noted

    Environmental geochemistry is an integral part of the mine-life cycle, particularly for modern mining. The critical importance of environmental geochemistry begins with pre-mining baseline characterization and the assessment of environmental risks related to mining, continues through active mining especially in water and waste management practices, and culminates in mine closure. The enhanced significance of environmental geochemistry to modern mining has arisen from an increased knowledge of the impacts that historical and active mining can have on the environment, and from new regulations meant to guard against these impacts. New regulations are commonly motivated by advances in the scientific understanding of the environmental impacts of past mining. The impacts can be physical, chemical, and biological in nature. The physical challenges typically fall within the purview of engineers, whereas the chemical and biological challenges typically require a multidisciplinary array of expertise including geologists, geochemists, hydrologists, microbiologists, and biologists. The modern mine-permitting process throughout most of the world now requires that potential risks be assessed prior to the start of mining. The strategies for this risk assessment include a thorough characterization of pre-mining baseline conditions and the identification of risks specifically related to the manner in which the ore will be mined and processed, how water and waste products will be managed, and what the final configuration of the post-mining landscape will be.In the Fall 2010, the Society of Economic Geologists held a short course in conjunction with the annual meeting of the Geological Society of America in Denver, Colorado (USA) to examine the environmental geochemistry of modern mining. The intent was to focus on issues that are pertinent to current and future mines, as opposed to abandoned mines, which have been the focus of numerous previous short courses. The geochemical

    Sand and gravel are widely used throughout the U.S. construction industry, but their extraction can significantly affect the physical, chemical, and biological characteristics of mined streams. Fisheries biologists often find themselves involved in the complex environmental and regulatory issues related to instream sand and gravel mining. This paper provides an overview of information presented in a symposium held at the 1997 midyear meeting of the Southern Division of the American Fisheries Society in San Antonio, Texas, to discuss environmental issues and regulatory procedures related to instream mining. Conclusions from the symposium suggest that complex physicochemical and biotic responses to disturbance such as channel incision and alteration of riparian vegetation ultimately determine the effects of instream mining. An understanding of geomorphic processes can provide insight into the effects of mining operations on stream function, and multidisciplinary empirical studies are needed to determine the relative effects of mining versus other natural and human-induced stream alterations. Mining regulations often result in a confusing regulatory process complicated, for example, by the role of the U.S. Army Corps of Engineers, which has undergone numerous changes and remains unclear. Dialogue among scientists, miners, and regulators can provide an important first step toward developing a plan that integrates biology and politics to protect aquatic resources.

    Morodi, T J; Mpofu, Charles

    2017-06-28

    This paper examines the issue of acid mine drainage in South Africa and environmental decision making processes that could be taken to mitigate the problem in the context of both conventional risk assessment and the precautionary principle. It is argued that conventional risk assessment protects the status quo and hence cannot be entirely relied upon as an effective tool to resolve environmental problems in the context of South Africa, a developing country with complex environmental health concerns. The complexity of the environmental issues is discussed from historical and political perspectives. An argument is subsequently made that the precautionary principle is an alternative tool, and its adoption can be used to empower local communities. This work, therefore, adds to new knowledge by problematising conventional risk assessment and proposing the framing of the acid mine drainage issues in a complex and contextual scenario of a developing country-South Africa.

    decreased the percentage of inhabitable land available to support society’s material needs. Presently, the land area available to supply the mineral resources, energy resources, water, food, shelter, and waste disposal needs of all Earth’s inhabitants is estimated to be 135 square meters per person. Continued global population growth will only increase the challenges of sustainable mining.Current trends in mining are also expected to lead to new environmental challenges in the future, among which are mine-waste management issues related to mining larger deposits for lower ore grade; water-management issues related to both the mining of larger deposits and the changes in precipitation brought about by climate change; and greenhouse gas issues related to reducing the carbon footprint of larger, more energy-intensive mining operations.

    2002-01-01

    Federal environmental impact assessment legislation has existed in Australia since 1974. A number of uranium mines have been developed in this time, utilizing a range of mining techniques, including opencut, underground and in-situ leach. Projects have also been undertaken in a variety of geographical areas requiring consideration of diverse biodiversity, cultural heritage and social impact issues. Assessment of uranium mining proposals in Australia is also conducted in a climate of political opposition from a cross section of the Australian community. This paper outlines some of the key issues that arose during recent assessments and which provide a lead to the role of environmental impact assessment in environmental policy development. Issues are also relevant to recent assessments on a replacement nuclear reactor, shipments of waste for reprocessing and proposed assessments on proposals for low and intermediate level nuclear waste facilities.

    The mining of uranium at the Ranger and Jabiluka mines in Australia's Northern Territory has been assessed as a case study for the environmental and social impact of uranium mining in Australia. The level of environmental protection achieved has been very high. However, a number of social indicators reveal that the social impact of development in the region, including the mining of uranium, has been significant. A program is now underway to redress these social issues. Links between social and environmental impact have been identified. In today's world, the standards and practices in environmental protection are as much determined by social attitudes as they are by scientific and technical assessment. (author)

    1998-01-01

    This paper discusses the principles and application of risk assessment and management as the basis for environmental management within the mining industry. Unlike in other industries, mines are required to obtain closure certificates in terms of section 12 for the South African Minerals Act, which should ultimately release them from further environmental responsibilities. The focus shifts from conventional minimum legal compliance management to management of real environmental risks. The risk assessment approach has been applied to the planning of mine closure at Iscor`s Durban Navigation Collieries (Durnacol) in Kwa-Zulu Natal and certain key risk issues such as the long-term risk of water pollution from coal discard dumps have already progressed to fully quantitative risk assessment. This paper discussed the process which has been followed to date, with particular emphasis on the most recent phase, namely quantitative risk assessment and management of pollution from coal discard dumps. it is believed that the approach that is being pioneered at Durnacoal and which overcomes some of the more obvious deficineices of both the Environmental Risk Assessment Management (EMPR) and the traditional process will ultimately serve as the mode for all responsible mines in South Africa. It is also believed that this approach will enable the authorities to issue closure certificates with the confidence that there will be no unforeseen surprises in the years after closure. 9 figs., 1 tab.

  14. Fact sheet on uranium exploration, mining production and environmental protection

    International Nuclear Information System (INIS)

    2006-01-01

    During the last 3 years, there has been a dramatic revival and comeback of the uranium industry in the light of the expanding nuclear power programme all over the world. As a result, there has been a boom in uranium exploration, mining and production activities to meet the higher demand of uranium and reduce the gap between uranium demand and uranium supply from mines. In coming years, additional requests for TC, training/workshop and CRPs are expected in the areas of: 1) advanced aerial and ground geophysical techniques for discovery of new deposits which could be deeply buried; 2) investigations of uranium sources in sedimentary, igneous and metamorphic environments; 3) In-Situ leaching (ISL) of uranium deposits; 4) advanced acid/alkali leaching of low, medium and high grade uranium ores and purification of uranium; 5) reclamation of used uranium mines and related environmental protection issues; and 6) uranium supply, demand and market issues. Services provided by the Nuclear Fuel Cycle and Materials Section could be workshops and hands-on field trainings at National and/or Regional levels in mines, mills and sites covering the following activities: uranium exploration involving conventional and advanced geophysical techniques and instruments, advanced drilling equipment and tools, etc.; uranium mining (open-cast and underground), recovery and purification by acid/alkali leaching, In-Situ leaching (ISL), purification by conventional and advanced solvent extraction and ion exchange techniques and concentration of uranium in the form of yellowcake (ammonium diuranate, magnesium diuranate and uranium peroxide); promoting best practices in uranium mining and milling (including tailing pond), covering environmental issues, reclamation of used uranium mines and chemistry of uranium production cycle and ground water and sustainability of uranium production.

    2016-01-01

    This paper reviews the environmental issues and management practices in the mining sector in the North America. The sustainable measures on waste management are recognized as one of the most serious environmental concerns in the mining industry. For mining activities, it will be no surprise that the metal recovery reagents and acid effluents are a threat to the ecosystem as well as hazards to human health. In addition, poor air quality and ventilation in underground mines can lead to occupational illness and death of workers. Electricity usage and fuel consumption are major factors that contribute to greenhouse gases. On the other hand, many sustainability challenges are faced in the management of tailings and disposal of waste rock. This paper aims to highlight the problems that arise due to poor air quality and acid mine drainage. The paper also addresses some of the advantages and limitations of tailing and waste rock management that still have to be studied in context of the mining sector. This paper suggests that implementation of suitable environmental management tools like life cycle assessment (LCA), cleaner production technologies (CPTs), and multicriteria decision analysis (MCD) are important as it ultimately lead to improve environmental performance and enabling a mine to focus on the next stage of sustainability.

  16. A review of the environmental management practices in the Indian mining sector

    2005-06-01

    The article, by the former director of the Indian school of Mines, Dhanbad, covers the major environmental management issues common to the majority of India's mining projects and gives recommendations for further improving practices, such as mine planning, fly ash utilization and conversion of mined lands to agriculture. India is likely to expand activities in mining of coal, iron ores, limestone and bauxite, mostly through opencast mining. The article mentions the regulations controlling environmental impacts of mining, the 1986 Environmental Protection Act and other measures. The 1994 Environmental Impact Assessment process was modified in 1997 to include the concept of public hearing. In 2003 the requirement of public hearing was limited to mines with lease area above 25 ha. In 2003 the Mineral Conservation and Development rules were amended to improve protection of the environment, reclamation and rehabilitation measures. Further deforestation cannot be avoided but the industry record for creating new forests on mined areas is improving. Issues of waste water treatment and dust abatement are outlined. 8 refs.

    This study investigates the influence of environmental performance on the financial report integrity. The statistics used were primary data from interviews with senior members of the mining sector regarding environmental issues, as well as secondary data using Financial Report 2016. The samples were listed mining companies with semester data. Questionnaires were used to measure their perceptions of the challenges concerning climate change faced by the mining sector. The results of this research show that regulatory interventions will be critical to environmental issues. This study employed KLD as a proxy for environmental performance, correlated with other variables regarding the integrity of disclosure. The outcome indicates that environmental issues will increase the integrity of financial reports.

    The extent to which the environment in the vicinity of the Ranger uranium mine has been protected throughout the past twenty years has been assessed on the basis of radiological, chemical and biological monitoring. Based on this experience, a risk assessment of the proposed development of the Jabiluka mine has been carried out. It is concluded that mining of uranium at Ranger has not given rise to adverse effects on the people or the ecosystems of Kakadu National Park and the natural values of the Park are not threatened by the development of the Jabiluka mine

    2009-01-01

    The International Symposium on Uranium Raw Material for the Nuclear Fuel Cycle: Exploration, Mining, Production, Supply and Demand, Economics and Environmental Issues (URAM-2009) addressed all aspects of the uranium fuel cycle, from the availability of raw materials to the long-term sustainability of nuclear power. The revival of the uranium industry in recent years has caused a dramatic increase in uranium exploration and mining activities in several countries. URAM-2009 was intended to bring together scientists, exploration and mining geologists, engineers, operators, regulators and fuel cycle specialists to exchange information and discuss updated research and current issues in uranium geology and deposits, exploration, mining and processing, production economics, and environmental and legal issues. Contributed papers covered uranium markets and economics (including supply and demand); social licensing in the uranium production cycle; uranium exploration (including uranium geology and deposits); uranium mining and processing; environmental and regulatory issues; human resources development. There was a poster session throughout the symposium, as well as an exhibition of topical photographs. A workshop on recent developments in Technical Cooperation Projects relevant to the Uranium Production Cycle area was also organized. On the last day of the symposium, there was an experts' Panel Discussion. The presentations and discussions at URAM-2009 (a) led to a better understanding of the adequacy of uranium sources (both primary and secondary) to meet future demand, (b) provided information on new exploration concepts, knowledge and technologies that will potentially lead to the discovery and development of new uranium resources, (c) described new production technology having the potential to more efficiently and economically exploit new uranium resources; (d) documented the environmental compatibility of uranium production and the overall effectiveness of the final

    2001-01-01

    The current phase of uranium mining in the Alligator Rivers Region of the Northern Territory of Australia began in the late 70's and is governed by a large number of legislative and administrative requirements. The primary responsibility for environmental regulation rests with the Northern Territory Government but the legislative framework is complex and involves agencies of the Commonwealth Government as well as the Aboriginal traditional owners. Two of the current uranium mining projects, Ranger and Jabiluka, are surrounded by the World Heritage listed Kakadu National Park. Thirteen former mines are located within the Park and one former mine, Nabarlek, is in the same catchment as part of the Park, in West Arnhem Land. For these reasons, environmental management at the operating mines has to be of the highest standard and environmental requirements are attached to all laws and agreements controlling the operating facilities. The paper describes the spirit and rationale behind the regulations as well as the operating details and methodology of the regulatory system in place for the operating mines. An integral part of the overall environmental protection regime is a bi-annual program of Environmental Audits and Environmental Performance Reviews and regular reporting to a stakeholder committee. Other elements include internal and external environmental auditing at the minesites as well as programs of routine monitoring, check monitoring and reporting on a scale and frequency rarely seen elsewhere. Public concern and perception is considered to be a valid issue requiring attention

  1. Environmental management frameworks for offshore mining: the New Zealand approach

    2017-07-27

    The New Zealand region contains untapped natural mineral, oil, and gas resources while also supporting globally unique and diverse faunal communities that need to be managed sustainably. In this paper key information from the international literature is reviewed that can underpin an Environmental Mining Management System which includes elements of Environmental Risk Assessment, Environmental Impact Assessment and Environmental Management Planning. This paper focuses on four developing areas of seafloor mining activities presently being undertaken or planned in the New Zealand region: hydrocarbons (oil and gas), minerals, ironsands and phosphorite nodules. A number of issues with the implementation of environmental management systems are identified including the difficulty of assessing new marine activities or technologies and the need for standardised reporting metrics. Finally, the development of ecosystem-based management and marine spatial planning is discussed which will be required to enhance environmental mining management frameworks in New Zealand.

    Liberia is endowed with an impressive stock of mineral reserves and has traditionally relied on mining, namely iron ore, gold, and diamonds, as a major source of income. The recent growth in the mining sector has the potential to contribute significantly to employment, income generation, and infrastructure development. However, the development of these mineral resources has significant environmental impacts that often go unnoticed. This paper presents an overview of the Liberian mining sector from historical, current development, and economic perspectives. The efforts made by government to address issues of environmental management and sustainable development expressed in national and international frameworks, as well as some of the environmental challenges in the mining sector are analyzed. A case study was conducted on one of the iron ore mines (China Union Bong Mines Investment) to analyze the effects of the water quality on the local water environment. The results show that the analyzed water sample concentrations were all above the WHO and Liberia water standard Class I guidelines for drinking water. Finally the paper examines the application of water footprint from a life cycle perspective in the Liberian mining sector and suggests some policy options for water resources management.

    2008-01-01

    This thesis work has analysed environmental impacts and health aspects in the mining industry of copper, uranium and gold with the aim of determining the relative performance, in a given set of parameters, of the uranium mining industry. A selection of fifteen active mining operations in Australia, Canada, Namibia, South Africa, and the United States of America constitute the subject of this study. The project includes detailed background information about mineral extraction methods, the investigated minerals and the mining operations together with descriptions of the general main health hazards and environmental impacts connected to mining. The mineral operations are investigated in a cradle to gate analysis for the year of activity of 2007 using the economic value of the product at the gate as functional unit. Primary data has been collected from environmental reports, company web pages, national databases and through personal contact with company representatives. The subsequent analysis examines the collected data from a resource consumption, human health and ecological consequences point of view. Using the Life Cycle Impact Assessment methodology of characterisation, primary data of environmental loads have been converted to a synoptic set of environmental impacts. For radiation and tailings issues, a more general approach is used to address the problem. Based on the collected data and the investigated parameters, the results indicate a presumptive relative disadvantageous result for the uranium mining industry in terms of health aspects but an apparent favourable relative result in terms of environmental impacts. Given the prerequisites of this study, it is not feasible to draw any unambiguous conclusions. Inabilities to do this are mainly related to inadequate data availability from mine sites (especially in areas concerning tailings management), and difficulties concerned with the relative valuation of specific performance parameters, in particular radiation

    Mining environmental liabilities (PAM from its acronym in Spanish) are areas where there is a need for restoration, mitigation or compensation for environmental damage or unmanaged impact, produced by inactive or abandoned mining that threatens health, quality of life or public or private property. In Colombia the environmental liabilities from mining have not been regulated, but given the age and the prevalence of informality in mining, there is increasing interest in defining, regulating and managing these obligations. In this paper we approach the problem of valuing mining environmental liabilities by examining different management approaches for such liabilities around the world. We also identify key information requirements to manage mining environmental liabilities in Colombia.

  7. Best Practice in Environmental Management of Uranium Mining

    International Nuclear Information System (INIS)

    2010-01-01

    The modern uranium mining industry was born in the middle of the 20th century at a time of rapid industrial and social change and in an atmosphere of concern over the development of nuclear weapons. At many uranium mining operations, the need to produce uranium far outweighed the need to ensure that there were any more than vestigial efforts made in protecting the workers, the public and the environment from the impacts of the mining, both radiological and non-radiological. In the last quarter of the 20th century, the world began to take greater care of the total environment with the introduction of legislation and the development of operating procedures that took environmental protection into account. The uranium mining industry was part of this change, and standards of environmental management began to become of significance in corporate planning strategies. However, by the 1980s, as uranium mining companies began to address the issues of environment protection, the industry began to suffer a cyclical slowdown. By the 1990s, the industry was at a nadir, but the surviving uranium producers continued to develop and implement a series of procedures in environmental management that were regarded as best practices. This, in part, was necessary as a means to demonstrate to the regulators, governments and the public that the mining operations were being run with the intention of minimizing adverse impacts on the workers, people and the environment. This ensured that mining would be allowed to continue. The decline in uranium mining activity bottomed out in the 1990s, but a resurgence of activity began in the new century that is likely to continue for some time. This has been, in part, due to market conditions and concerns about the shortfall of current production from primary sources (uranium mines) against current reactor fuel demands; the anticipated decrease in future availability of secondary sources such as stockpiles; and the increased interest in nuclear power

    2005-12-15

    Illustrated by a detailed comparative examination of mining regulations and environmental impact assessment (EIA) in the USA (the second largest producer of coal in the world) and Indonesia (the eighth largest and most rapidly growing), this book argues that the degree of policy integration often determines the success or failure in controlling environmental effects of mining operations. Comparison of surface mining regulation in the two countries provides some stark contrasts, some surprising results concerning the diffusion of policy innovations from one country to another, and instances of both policy success and failure. The book provides significant new insights into international relations and comparative environmental policy, particularly as they affect rainforests and biodiversity. It also suggests that if mining environmental policy were to be effectively implemented, the environmental degradation caused need not be permanent. Contents: Introduction: mining environmental policy implementation in two countries; Mining regulatory policy in Indonesia; Mining regulatory policy in the United States; Environmental assessment policy in two countries; Lost profits, royalties, and environmental quality; Developing mining environmental policy in Indonesia; Improving Indonesian regulatory program; Development of institutional capacity; Motivations for assistance; Conclusions.

    The causes for the failure in enforcement of environmental regulations at the Giap Lai pyrite mine in northern Vietnam are considered and the environmental impacts that are associated with this mine are evaluated. It is shown that sulphide-rich tailings and waste rock in the mining area represent significant sources of acid rock drainage (ARD). The ARD is causing elevated metal levels in downstream water bodies, which in turn, represent a threat to both human health and to aquatic ecosystems. Metal concentrations in impacted surface waters have increased after mine closure, suggesting that impacts are becoming progressively more serious. No post-closure, remediation measures have been applied at the mine, in spite of the existence of environmental legislation and both central and regional institutions charged with environmental supervision and control. The research presented here provides further emphasis for the recommendation that, while government institutions may need to be strengthened, and environmental regulations need to be in place, true on the ground improvement in environmental quality in Vietnam and in many other developing countries require an increased focus on promoting public awareness of industrial environmental issues.

    Institutional control of a mine site is required to ensure long-term public safety and environmental protection once responsibility for a decommissioned uranium mine site reverts back to the Crown. During the exploration, development, operation and decommissioning phases of a uranium mine's life cycle, public safety and environmental protection are ensured through the Federal and Provincial Environmental Assessment Review process, regulatory permitting and compliance monitoring by the province. However, at present, there is no clear provincial policy with respect to a proponent's application for release from a reclaimed and decommissioned site, and the resulting provincial responsibility for the long-term management and maintenance of the site once a release has been granted. Another policy issue has been identified with respect to the long-term institutional control of previously abandoned uranium mine sites. A number of issues are being considered by the Government of Saskatchewan in developing a policy which addresses the needs of the people of Saskatchewan and which is consistent with the intent of the commitments made by Canada through its ratification of the International Atomic Energy Agency's (IAEA) Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management.

    Recent investigations of uranium mining and milling activities in the Grants Mineral Belt of New Mexico revealed serious environmental problems associated with these activities. An investigation was undertaken in the South Texas Uranium Belt to determine whether or not similar or other environmental problems existed. The study describes: (1) the history of uranium mining and milling in South Texas, (2) the area economy and demography, (3) the occurrence of uranium ore and (4) the regulatory aspects of uranium mining and milling in South Texas. The commercial recovery and processing of uranium in this area is described in some detail. Exploration, open pit mining, in-situ solution mining and processing techniques for ''yellowcake'' (U 3 O 8 ), the uranium product of the area, are discussed. The state and federal regulations pertinent to uranium mining and milling are summarized. Finally, the environmental effects of these activities are discussed and conclusions and recommendations are drawn

    Mining in India has been diversifying into progressively more capital intensive and energy intensive areas which are degrading the quality of environment. Considering the future environmental and energy scenarios, the impact the mining has on environmental quality and occupational health/safety of mine workers, Environmental Audit (EA) deserves to be adopted as a pre-requisite for sustainable development and environmental management of Indian mines. EA is a structured and comprehensive mechanism for ensuring that the mining activities do not adversely affect the environmental quality and the economy of mining sector improves as a consequence of improved process and energy effectiveness as also the occupational health and safety. This paper emphasizes that the successful EA program investigates all possibilities of energy saving, material saving and water budgeting through conservation of resources to protection of environment. The paper presents the various options for environmental management in mining industry, including reactive control measures on one hand and anticipative/preventive strategies on the other. The paper also reviews the EA skills and audit protocols along with a discussion of key audit techniques. 12 refs., 5 figs

    Producing uranium in a safe and environmentally responsible manner is important not only to the producers and consumers of the product, but also to society at large. Given expectations of growth in nuclear generating capacity in the coming decades - particularly in the developing world - enhancing awareness of leading practice in uranium mining is important. This was the objective of a recent NEA report entitled Managing Environmental and Health Impacts of Uranium Mining, providing a non-technical overview of the significant evolution of uranium mining practices from the time that it was first mined for military purposes until today.

    Much has been said and written in recent years about the greatly increased difficulties faced by the mining industry in meeting the expectations of local communities and in adequately protecting the natural environment. The impression is often given that the industry was completely oblivious of such concerns and needs until the present decade, and that it is now struggling to make up for past neglect. Certainly the standards required by society as a whole have risen, and there is more public discussion that in earlier times, but the management of many major mining companies have long been fully aware of their obligations to the environment and local communities. To argue otherwise would be to misread the history of the industry and to perform a grave disservice to many dedicated managers of the mining projects of former years. (author)

    This IAEA symposium is a third in a series which began in 2000 to discuss issues related to uranium raw materials. The symposia covered all areas of the uranium production cycle — including uranium geology, exploration, mining; milling and refining of uranium concentrates; and safety, environmental, social, training and regulatory issues — and reported on uranium supply and demand, and market scenarios. The first symposium was held in October 2000 — a time of extremely depressed market prices for uranium and of mines being closed — and primarily addressed environmental and safety issues in the uranium production cycle. By the time the second symposium was held in June 2005, the uranium market had started to improve after nearly two decades of depressed activity because of increased demand due to rising expectations for nuclear power expansion. Since then, there has been a dramatic rise in the uranium spot price, which in turn has promoted a significant increase in uranium exploration activities all over the world. The international symposium on Uranium Raw Material for the Nuclear Fuel Cycle (URAM-2009) was held at the IAEA, Vienna, 22–26 June 2009, at a time when nuclear energy was emerging as a viable alternative to meet the ever increasing demand of electricity in a sustainable manner, without degrading the environment. However, the global recession and credit crunch could impact the growth of the uranium industry. Since 2000, the identified uranium resource base has grown by more than 75%, exploration efforts have continued to increase in greenfield as well as brownfield sites, annual uranium production has risen, and the issue of social licensing and uranium stewardship has become increasingly important for public acceptance of the uranium industry. Some 210 delegates from 33 States and four international organizations participated in the symposium.

    Uranium is the raw material used to produce fuel for nuclear power plants that generate significant amounts of electricity with life cycle carbon emissions that are as low as renewable energy sources. However, the mining of this valuable energy commodity remains controversial, principally because of environmental and health impacts associated with the early years of uranium mining. Maximising production in the face of rapidly rising demand was the principal goal of uranium mining at the time, with little concern given to properly managing environmental and health impacts. Today, societal expectations and regulation of the industry are directed much more towards radiation protection, environmental stewardship, health and safety. With over 430 operational reactors in the world, nuclear fuel will be required for many decades in order to meet requirements to fuel the existing fleet and demand created by new reactors, given the projected growth in nuclear generating capacity, particularly in the developing world. New mines will in turn be needed. As a result, enhancing awareness of leading practices in uranium mining is increasingly important. This report aims to dispel some of the myths, fears and misconceptions about uranium mining by providing an overview of how leading practice mining can significantly reduce all impacts compared to the early strategic period. It also provides a non-technical overview of leading practices, the regulatory environment in which mining companies operate and the outcomes of implementing such practices. Societal expectations related to environmental protection and the safety of workers and the public evolved considerably as the outcomes of the early era of mining became apparent, driving changes in regulatory oversight and mining practices. Uranium mining is now conducted under significantly different circumstances, with leading practice mining the most regulated and one of the safest and environmentally responsible forms of mining in the

    As the raw material that fuels nuclear power plants that generate significant amounts of electricity with full life cycle carbon emissions as low as renewable energy sources, uranium is a valuable commodity. Yet uranium mining remains controversial, principally because of environmental and health impacts created when mining was undertaken by governments to meet Cold War strategic requirements. Uranium mining is conducted under significantly different circumstances today. Since the era of military production, societal expectations of environmental protection and the safety of workers and the public have evolved as the outcomes of the early era of mining became apparent, driving changes in regulatory oversight and mining practices. Key aspects of leading practice uranium mining are presented (conventional worker health and safety, worker radiation protection, public health and safety, water quality, tailings and waste rock management) and compared with historic practices to demonstrate the scale of differences. The application of additional aspects of uranium mine life cycle management (public consultation, environmental impact assessment, analysis of socio-economic impacts/benefits, environmental monitoring, financial assurance, product transport, security and safeguards, emergency planning and knowledge transfer), introduced as the industry matured, enhance overall management practices for the long term. Results from several case studies show that improved management of key aspects of uranium mining, combined with the incorporation of new life cycle parameters, have transformed the industry into the most regulated and arguably one of the safest and environmentally responsible types of mining in the world.

    Full Text Available Mining has gained strong popularity in recent years due to the increase in global demand for metals and other industrial raw material derived from the ground. However, information and good governance regarding activities related to mining is still very much lacking especially in underdeveloped and developing countries in the tropics. In Malaysia, the importance of environmental stewardship in mining is a new phenomenon. The new National Mineral Policy 2 calls for compliance with existing standards and guidelines, stresses on progressive and post mining rehabilitation as well as promotes the gathering and dissemination of information, best mining practices, public disclosure and corporate social responsibility. Our preliminary studies however have shown that its implementation may have been hampered by inadequate legal and administrative structures, lack of freedom of information, physical inaccessibility, lack of information and public participation. In this presentation, the above issues and measures to reduce the impact of mining, particularly that of gold on the environment with a special focus on Malaysia is discussed. These measures include alternative gold extraction methods, appropriate tailing dam construction and management, health risk assessment and risk management, compliance with the Cyanide Code and liberalization of access to information, facilitation of access to justice, the strengthening of legal and administrative structures as well as corporate accountability to the public as part of corporate social responsibility.

    The department of Energy (DOE) views as one of its most challenging problems the minimization, management, and cleanup of waste materials generated from Departmental operations. The challenges for the DOE have striking similarities to the environmental restoration and waste management challenges associated with energy production and the mining and mineral processing industries. Their challenges relate to uranium mining and the resulting mill tailings; decontamination and decommissioning of facilities; processing of nuclear materials and production of weapons components. Add to this the challenge of environmental restoration solutions for waste disposal practices of the past. The fundamental goal of the DOE is to ensure that risks to human health and safety and to the environment posed by the department's past, present, and future operations are either eliminated to reduced to prescribed levels by the year 2019. To achieve this goal they must be able to assess environmental and health impacts resulting from the low concentrations of contaminants. This paper presents an overview of the causes, characteristics, and cures for these environmental restoration and waste management issues

    The growing environmental pressure of mineral deposit surface mining and severization of industrial safety requirements dictate the necessity of refining the regulatory framework governing safe and efficient development of underground resources. The applicable regulatory documentation governing the procedure of ore open-pit wall and bench stability design for the stage of pit reaching its final boundary was issued several decades ago. Over recent decades, mining and geomechanical conditions have changed significantly in surface mining operations, numerous new software packages and computer developments have appeared, opportunities of experimental methods of source data collection and processing, grounding of the permissible parameters of open pit walls have changed dramatically, and, thus, methods of risk assessment have been perfected [10-13]. IPKON RAS, with the support of the Federal Service for Environmental Supervision, assumed the role of the initiator of the project for the development of Federal norms and regulations of industrial safety "Rules for ensuring the stability of walls and benches of open pits, open-cast mines and spoil banks", which contribute to the improvement of economic efficiency and safety of mineral deposit surface mining and enhancement of the competitiveness of Russian mines at the international level that is very important in the current situation.

    From the international context at the regional level, the mining activity in Colombia is subject to the execution of norms of environmental character or environmental miner that define it in some way. This norma has suffered important transformations determined by the fundamental juridical changes that especially in the last ten years they have been given so much in the environmental sector as the mining sector, as well as for the jurisprudence especially of the constitutional court on these matters. These aspects were in their majority, analyzed in a combined way for the mining and environmental authorities, in the juridical forum of the environmental national system in that the proposal of the CDMB, Corantioquia and Corpouraba, it approaches this like discussion topic, likewise the technical documents that supported the expedition of the environmental guides miner, were fed by the combined work of mining and environmental authorities. These confluence points should be fundamentally disclosed and well-known inside the mining sector as of the environmental sector in order to that, not only has clear which is at the moment the environmental mining norma effective, but rather it is also had the necessary tools to give to this normative, the interpretation and appropriate application. The different implications that it introduced the law 685 of 2001 in environmental matter, will be analyzed by the light of the jurisprudence and the new norms settled down in environmental matter, such as the Sentences C-431 2000, C-336 2000, C-339 2002 and the Ordinances 2390 of 2002, 2653 of 2003, 1180 of 2003, among other, especially in connection with topics as the contents in the Chapter III of the Law 685 of 2001 reserved, excluded and restricted areas, the topic of the environmental licenses and that of the legalization of the mining in fact, making a priori in this analysis an evaluation from the point of view of the environmental authority in connection with the efficiency and

    Maest, A.

    1990-01-01

    Working with the Environmental Mining Network, a coalition of ∼75 environmental groups nationwide formed to encourage environmentally-sound hard-rock mining. Emphasis is on changing the industrial process so that wastes are not created in the first place, instead of creating the wastes and dealing with them as an afterthought. The tradition of pollution control is slowly being replaced with prevention. Objectives of pollution prevention for mining include: Reduction of the volume of material extracted, beneficiated, processed, and removed for exploration by improving techniques for these processes, mining less, and encouraging remining and use of scrap materials; Reduction of the toxicity and environmental impact of wastes that are nonetheless generated by employing techniques that minimize the release of contaminants to the environment; Identifying current and developing technologies for pollution prevention in the mining industry and distribute this among the regulated community. Pollution prevention should be incorporated in design and performance standards. Assessment and demonstration of pollution prevention should be part of the permit application. Implementation of serious non-rhetorical pollution prevention by the mining industry has the potential to give miners and environmentalists a common ground and common goals where we could truely be in a win-win situation in terms of encouraging both environmental and economic robustness

    Full Text Available Sustainable mining is an objective as well as a tool for balancing economic, social, and environmental considerations. Each of these three dimensions of mining – and sustainable development – has many components, some of which were chosen for closer study in the SUMILCERE project. While there is no single component that in itself provides a definitive argument for or against sustainable mining, the research reveals some that have proven valuable in the process of balancing the different dimensions of sustainability. In the SUMILCERE project, comparative studies enabled us to identify factors such as the following, which are essential when discussing the balancing in practice of the three dimensions of sustainable mining cited above: the framework and functionality of environmental regulation to protect the environment (environmental sustainability; competitiveness of the mining industry in light of environmental regulation and its enforcement (economic sustainability; public participation and the opportunities local communities have to influence their surroundings, as well as communities’ acceptance of projects (social sustainability before and during operations; and the protection of Sámi cultural rights in mining projects (social and cultural sustainability. Although each of the three dimensions of sustainability leaves room for discretion in the weight assigned to it, ecological sustainability, protected by smart environmental regulation and minimum standards, sets essential boundaries that leave no room for compromises. Economic and social sustainability are possible only within these limits. Details of the analyses in the Kolarctic area and accounts of the methods used can befound in the cited SUMILCERE articles.

  9. Legal issues concerning mine closure and social responsibility on the West Rand

    2009-04-01

    Full Text Available Mining and, especially, gold and uranium mining have played a major role in the economy, history, and demography of South Africa. The contribution of the mines to the economy of South Africa over the past century has been overvalued, while the social injustices and negative environmental impacts that accompanied mining have been underplayed or ignored by the mining houses and government. The environmental situation has worsened significantly over the past few years due to the abandonment and pending closure of most of these mines. A reluctance is perceived on the part of the mining companies, and even government, to take responsibility for the damage caused by pollution, ecological degradation, and impact on human health by mining. Instead, the current informal policy appears to take smaller companies to court on minor environmental injustices to, perhaps, impress the broader public, while one of the biggest environmental concerns is stylishly treated. The inability of government to address the damage by mines effectively is in conflict with the National Water Act, the National Environmental Management Act, the Mineral and Petroleum Resources Act, the National Nuclear Regulator Act, and the Constitution of South Africa. The authors propose a multidisciplinary approach to address water-related environmental injustices on the West Rand and Far West Rand. We also describe the application of the National Environmental Management Act of South Africa (Act No. 107 of 1998 in the Wonderfonteinspruit and Tweelopiespruit Catchments and the current water quality situation.

The special attention given to tailings management is highlighted, and a discussion of the basic environmental concerns is concluded with an itemizing of the main tasks facing the AECB. The extent of the environmental impact of uranium mining, milling and waste management is illustrated with specific details pertaining to mines in the Elliot Lake area. The author concludes that the impact on the ground and surface water system is not alarming, and the impact on air quality is not significant beyond a few hundred metres from the mining facilities. The publicly perceived impact is discussed, followed by a rationale for the continued licensing of new uranium mining operations complete with tailings management facilities

    The Gunnar Mine and mill site was the largest of some 38 now-abandoned uranium mines that were developed and operated in Northern Saskatchewan, Canada, during the Cold War years. During their operating lifetimes these mines produced large quantities of ore and tailings. The Gunnar mine (open pit and underground) produced over 5 million tonnes of uranium ore and nearly 4.4 million tonnes of mine tailings during its operations from 1955 through 1963. An estimated 2.2 to 2.7 million m{sup 3} of waste rock that was generated during the processing of the ore abuts the shores of Lake Athabasca, the 22. largest lake in the world. After closure in the 1960's, the Gunnar site was abandoned with little to no decommissioning being done. The Saskatchewan Research Council has been contracted to manage the clean-up of these abandoned northern uranium mine and mill sites. The Gunnar Mine, because of the magnitude of tailings and waste rock, is subject to an environmental site assessment process regulated by both provincial and federal governments. This process requires a detailed study of the environmental impacts that have resulted from the mining activities and an analysis of projected impacts from remediation efforts. The environmental assessment process, specific site studies, and public involvement initiatives are all now well underway. Due to the many uncertainties associated with an abandoned site, an adaptive remediation approach, utilizing a decision tree, presented within the environmental assessment documents will be used as part of the site regulatory licensing. A critical early task was dealing with major public safety hazards on the site. The site originally included many buildings that were remnants of a community of approximately 800 people who once occupied the site. These buildings, many of which contained high levels of asbestos, had to be appropriately abated and demolished. Similarly, the original mine head frame and mill site buildings, many of which

    Full Text Available Environmental noise constitutes a threat regarding disturbance and deterioration of quality of living. There are numerous sources of environmental noise, among others mine objects, traffic roads etc. In Serbian practice open cast mines are commonly in vicinity of residential areas, which is the case of the Field C open cast coal mine and the Barosevac settlement. More complexity is added to noise management in such conditions through additional noise sources, not directly linked to mine objects and activities, such as local or regional roads. This paper describes an approach to noise management for the purpose of environmental noise impact reduction, from both traffic and industrial sources, related to the project Environmental Improvement Project in Kolubara Mine Basin in Barosevac settlement, as a part of acquisition of new Excavator-belt Conveyor-Stacker (ECS system.

    Due to the large amount and complexity of data available nowadays in geo- and environmental sciences, we face the need to develop and incorporate more robust and efficient methods for their analysis, modelling and visualization. An important part of these developments deals with an elaboration and application of a contemporary and coherent methodology following the process from data collection to the justification and communication of the results. Recent fundamental progress in machine learning (ML) can considerably contribute to the development of the emerging field - environmental data science. The present research highlights and investigates the different issues that can occur when dealing with environmental data mining using cutting-edge machine learning algorithms. In particular, the main attention is paid to the description of the self-consistent methodology and two efficient algorithms - Random Forest (RF, Breiman, 2001) and Extreme Learning Machines (ELM, Huang et al., 2006), which recently gained a great popularity. Despite the fact that they are based on two different concepts, i.e. decision trees vs artificial neural networks, they both propose promising results for complex, high dimensional and non-linear data modelling. In addition, the study discusses several important issues of data driven modelling, including feature selection and uncertainties. The approach considered is accompanied by simulated and real data case studies from renewable resources assessment and natural hazards tasks. In conclusion, the current challenges and future developments in statistical environmental data learning are discussed. References - Breiman, L., 2001. Random Forests.

    Mining is a hazardous operation which must be designed to succeed under very unpredictable environmental, geological and marketing conditions over a committed life of thirty years or longer. It is well-established by now that mining has tremendous social, economic and environmental impacts on society in general and on local communities in particular. Mining's image has begun to improve with effective hazard controls and property reclamation through improved mine design and restoration plans. Much of the credit for this achievement should go to Environmental Impact Statement and related permitting requirements for mining projects. An Environmental Impact Statement with respect to almost every type of mining project is now frequently required by major banks, and other funding agencies, governmental agencies and/or citizen groups involved in the permitting process. This impact statement ensures that the proposed project has the potential to succeed under all foreseeable environmental, geological and marketing problems throughout its projected life and to guarantee the return of the initial capital with interest. In short, the impact statement offers assurance that the final project will culminate with positive environmental and social impacts. The relevance and contributions of Environmental Impact Statements in mine design, as well as their applications and development procedures are presented. 3 refs., 8 figs

    Environmental degradation associated with mining activities may seriously threaten the health of local people and the sustainable development of coal mining, which may need to be addressed by improved environmental evaluation system. Based on analyzing environmental pollution from coal mining and the increasing need for raw coal, this paper establishes an environmental evaluation system, covering environmental situation, resource protection and economic benefit, for sustainable development in coal mining. This paper proposes methods for calculating the weight of each index and the environmental sustainable capability taking into account the method of Analytic Hierarchy Process (AHP). Finally, the index system is used to evaluate the environmental sustainability of coal mining in the Qijiang area, Western China, which has demonstrated the validity of the index system. It may also be useful as a tool to assess the environmental impact of mining areas, as well as a measure to promote sustainable development in coal mining. (author)

    Polluting mine accidents and widespread environmental contamination associated with historic mining in Europe and elsewhere has triggered the improvement of related environmental legislation and of the environmental assessment and management methods for the mining industry. Mining has some unique features such as natural background pollution associated with natural mineral deposits, industrial activities and contamination located in the three-dimensional sub-surface space, the problem of long-term remediation after mine closure, problem of secondary contaminated areas around mine sites and abandoned mines in historic regions like Europe. These mining-specific problems require special tools to address the complexity of the environmental problems of mining-related contamination. The objective of this paper is to review and evaluate some of the decision support methods that have been developed and applied to mining contamination. In this paper, only those methods that are both efficient decision support tools and provide a 'holistic' approach to the complex problem as well are considered. These tools are (1) landscape ecology, (2) industrial ecology, (3) landscape geochemistry, (4) geo-environmental models, (5) environmental impact assessment, (6) environmental risk assessment, (7) material flow analysis and (8) life cycle assessment. This unique inter-disciplinary study should enable both the researcher and the practitioner to obtain broad view on the state-of-the-art of decision support methods for the environmental assessment of contamination at mine sites. Documented examples and abundant references are also provided.

    The environmental impact of coal mining and burning of coal is evident and generally easy to understand. However, students often struggle to understand the social impacts of coal mining. A jigsaw activity culminating in a mock town hall meeting helps students link social, economic and environmental impacts of coal mining. Students are divided into four groups and assigned the task of researching the environmental, social, economic or health impacts of coal mining in West Virginia. When students have completed the research, they are assigned a role for the town hall. Roles include local community members, direct employees of the coal industry, business owners from industries related to coal mining, and environmentalists. One student from each research area is assigned to each role, forcing students to consider environmental, social, health and economic aspects of coal mining in choosing an appropriate position for their role. Students have 30 minutes to prepare their positions and then present for 2-5 minutes in the simulated town hall. We then have open class discussion and review the positions. Finally, students are required to write a letter to the editor of the local paper. The specific topic for the town hall and letters can be varied based on current events and could include new regulations on power plants, mine safety, government funding of alternative energy supplies or a range of other topics. This approach forces students to consider all aspects of the issue. In addition, because students have to assume a role, they are more aware of the direct impact that coal mining has on individuals' lives.

  7. The Imposition Environmental Cost-Loading Of Companies Investing In Coal Mining

    Full Text Available The instrument of environment is an effort to prevent environmental problems caused by mining activities both in forms and its nature. The aims of the study are to analyze and understanding the essence of environment cost-loading in order to restore the environment from coal mining activities both when mining taken place and post-mining. The type of research used is a normative-legal research. This research was conducted in the province of South Kalimantan with the consideration that the South Kalimantan is one of the largest coal-producing Provinces in Indonesia. In addition the environment cost-loading for investor in coal mining have the same properties in all coal mining sites in Indonesia. The results of the research indicated that the imposition and environment-cost in investment activity in the field of coal mining can be seen from the two approaches i.e the economic and legal approach. Economic approach is an approach that emphasizes the economic benefits gained by the owner of activities when they comply with the environmental requirements stipulated by laws and environmental regulations. Realizing the importance of environmental cost-loading for the company that manages the coal mining especially for the utilization of prevention of pollution caused by coal mining activity it is necessary to develop an institutional guarantee of recovery from the effects of pollution by establishing fund insurance for environmental restoration as a result of pollution. Thus in order to optimize the implementation of guarantee fund for environmental restoration are specifically utilized for post-mining reclamation then granting the status of Clean and Clear C amp C for coal mining investor must be presupposing the proof of guarantee fund has been placed for environmental restoration post-mining.

    The mining sector is growing in parallel with societal demands for minerals. One of the most important environmental issues and economic burdens of industrial mining on land is the safe storage of the vast amounts of waste produced. Traditionally, tailings have been stored in land dams, but the lack of land availability, potential risk of dam failure and topography in coastal areas in certain countries results in increasing disposal of tailings into marine systems. This review describes the different submarine tailing disposal methods used in the world in general and in Norway in particular, their impact on the environment (e.g. hyper-sedimentation, toxicity, processes related to changes in grain shape and size, turbidity), current legislation and need for future research. Understanding these impacts on the habitat and biota is essential to assess potential ecosystem changes and to develop best available techniques and robust management plans.

    Mine closure planning considers the best ways to plan and manage the environmental changes and socio-economic effects associated with the closing of mines. While the criteria for judging successful closures may vary, it is particularly important for physical, chemical and biological stability to be achieved and for final land use to be appropriate. Trust funds are increasingly favoured as a practical means of fulfilling the requirement for a financial surety and of ensuring that financial provision is available at the end of the mine's life.

    Environmentally acquired asbestos-related diseases (ARDs) are of concern globally. In South Africa, there is widespread contamination of the environment due to historical asbestos mining operations that were poorly regulated. Although the law makes provision for the compensation of occupationally acquired ARDs, compensation for environmentally acquired ARDs is only available through the Asbestos Relief Trust (ART) and Kgalagadi Relief Trust, both of which are administered by the ART. This study assessed ARDs and compensation outcomes of environmental claims submitted to the Trusts. The personal details, medical diagnoses, and exposure information of all environmental claims considered by the Trusts from their inception in 2003 to April 2010 were used to calculate the numbers and proportions of ARDs and compensation awards. There were 146 environmental claimants of whom 35 (23.9%) had fibrotic pleural disease, 1 (0.7%) had lung cancer, and 77 (52.7%) had malignant mesothelioma. 53 (36.3%) claimants were compensated: 20 with fibrotic pleural disease and 33 with mesothelioma. Of the 93 (63.7%) claimants who were not compensated, 33 had no ARDs, 18 had fibrotic pleural disease, 1 had lung cancer, and 44 had mesothelioma. In addition to having ARDs, those that were compensated had qualifying domestic (33; 62.2%) or neighbourhood (20; 37.8%) exposures to asbestos. Most of the claimants who were not compensated had ARDs but their exposures did not meet the Trusts' exposure criteria. This study demonstrates the environmental impact of asbestos mining on the burden of ARDs. Mesothelioma was the most common disease diagnosed, but most cases were not compensated. This highlights that there is little redress for individuals with environmentally acquired ARDs in South Africa. To stop this ARD epidemic, there is a need for the rehabilitation of abandoned asbestos mines and the environment. These issues may not be unique to South Africa as many countries continue to mine and use

    Surface coal mines being the largest contributor to the national coal production, the study of environmental impacts due to this becomes mandatory as it will help in proper planning and safe operations of the mine in an environmentally compatible manner. Within the scope of this paper, a model for preparation of comprehensive environmental impact assessment (EIA) by utilising a new evaluation methodology leading to determination of Environmental Quality Designation an index has been developed and this model has been validated by using data from a running surface coal mine in Wardha Valley Coalfield. Based on this exercise, the overall impact of the surface coal mine under consideration on environment indicates a medium level and accordingly the control measures have to be planned. Thus repair to the environment has to be made a concurrent activity with mining i.e. to say we have to design with nature not against it

    Every year, all around the world, global environmental change affects the human habitat. This is effect enhanced by the mining operation, and creates new challenges in relationship between the mining and local community. The purpose of this project are developed the Stakeholders engagement evaluation plan which is currently developed in University of Nevada, Reno for the Emigrant mining project, located in the central Nevada, USA, and belong to the Newmont Mining Corporation, one of the gold production leader worldwide. The needs for this project is to create the open dialog between Newmont mining company and all interested parties which have social or environmental impacts from the Emigrant mine. Identification of the stakeholders list is first and one of the most difficult steps in the developing of mine social responsibility. Stakeholders' engagement evaluation plan must be based on the timing and available resources of the mining company, understanding the goals for the engagement, and on analyzes of the possible risks from engagement. In conclusion, the Stakeholders engagement evaluation plan includes: first, determinations of the stakeholders list, which must include any interested or effected by the mine projects groups, for example: state and local government representatives, people from local communities, business partners, environmental NGOs, indigenous people, and academic groups. The contacts and availability for communication is critical for Stakeholders engagement. Next, is to analyze characteristics of all these parties and determinate the level of interest and level of their influence on the project. The next step includes the Stakeholders matrix and mapping development, where all these information will be put together.After that, must be chosen the methods for stakeholders' engagement. The methods usually depends from the goals of engagement (create the dialog lines, collect the data, determinations of the local issues and concerns, or establish

    This paper presents a novel approach to environmental assessment of coal mining operations, which enables assessment of the factors that are both directly and indirectly affecting the environment and are associated with the production of raw materials and energy used in processes. The primary novelty of the paper is the development of a computational environmental life cycle assessment (LCA) model for coal mining operations and the application of the model for coal mining operations in Poland. The LCA model enables the assessment of environmental indicators for all identified unit processes in hard coal mines with the life cycle approach. The proposed model enables the assessment of greenhouse gas emissions (GHGs) based on the IPCC method and the assessment of damage categories, such as human health, ecosystems and resources based on the ReCiPe method. The model enables the assessment of GHGs for hard coal mining operations in three time frames: 20, 100 and 500 years. The model was used to evaluate the coal mines in Poland. It was demonstrated that the largest environmental impacts in damage categories were associated with the use of fossil fuels, methane emissions and the use of electricity, processing of wastes, heat, and steel supports. It was concluded that an environmental assessment of coal mining operations, apart from direct influence from processing waste, methane emissions and drainage water, should include the use of electricity, heat and steel, particularly for steel supports. Because the model allows the comparison of environmental impact assessment for various unit processes, it can be used for all hard coal mines, not only in Poland but also in the world. This development is an important step forward in the study of the impacts of fossil fuels on the environment with the potential to mitigate the impact of the coal industry on the environment. - Highlights: • A computational LCA model for assessment of coal mining operations • Identification of

    Bath, L.J.

    1984-01-01

    Ranger Uranium Mines operates an open cut located in the Northern Territory. Strict environmental controls govern all operations and the water management requirements have the greatest impact on mine planning. The two main goals of planning are to provide mill feed and to mine sufficient suitable quality waste rock for ongoing construction of the tailings dam. Early planning concentrated on staged development of the pit to provide access to as much ore as possible for a given amount of development. All waste was considered to be suitable construction material. Grade control of crusher feed was the main problem in planning, as wide variations occur in ore grade over relatively short distances. Water management for the site operates a 'no release' system for contaminated waters. Design storage has proven inadequate, and the open cut has been used as the extra storage. As construction of future stages of the tailings dam requires non-mineralised rock materials which meet specific quality criteria, the mine has had to re-examine long term planning and pit development strategies. This has entailed the collection of much data not required under normal mining conditions, such as the assaying of waste drill core. The overall impact on mine planning of the environmental regulations has been to alter the philosophy of earlier planning, making it necessary to create a new strategy for pit development with the accent on exposing waste

    As one of many activities TVA has undertaken to ensure an adequate supply of uranium for these plants, TVA has proposed to underground mine, through its operator, the uranium deposits located in the Canon de Marquez in McKinley County, New Mexico. Construction and operation of the underground mine would be expected to have the following environmental effects: (a) a temporary change in land use for 48.5 hectares from wildlife habitat and recreation to mineral extraction; (b) a minor alteration in topography near the proposed pond sites due to reclamation of waste rock piles; (c) minimal impacts on land due to limited vehicular traffic and road construction; (d) temporary depression of ground water levels in the Westwater Canyon Member of the Morrison Formation in the mine vicinity during mine life; (e) short-term project-induced impacts to surface water and shallow ground water quality; (f) a temporary decrease in air quality in the vicinity of the mining operations due to fugitive dust and exhaust emissions from combustion-driven mining and support vehicles and releases of radon and short-lived radon progeny from ventilation shafts and ore piles; (g) a temporary decrease of plant and animal species at the mine site; (h) a minor and temporary effect on aquatic systems downstream from the mine and settling ponds due to sedimentation; and (i) a minor increase of noise levels in the immediate vicinity of mine shafts and vents. The no action alternative and alternatives for securing uranium ore by other methods were considered but were found insufficient to meet TVA objectives. None of the alternatives explored were environmentally preferable. TVA also evaluated site specific alternatives including the following: different shaft and support building siting, mining techniques, and reclamation options. 25 figures, 20 tables

    This paper offers a new perspective on the environmental laws in Asian nations affecting the exploration, mining, and reclamation activities of the mineral resource industry: the perspective of the senior government officials in those countries, whose job is to enforce these new environmental laws. The article presents the results of a 1998 survey of national environmental officials in Asia conducted by the Colorado School of Mines and the Metal Mining Agency of Japan. Officials in 10 diverse countries - Cambodia, China, Indonesia, Lao PDR, Malaysia, Myanmar, Mongolia, Philippines, Thailand and Vietnam - responded to a detailed questionnaire covering applicable laws, agencies, protected areas, covered mineral activities, financial assurance, environmental impact assessment, public involvement, environmental standards, permit and reclamation requirements. The survey confirms that Asian nations are part of the global trend towards national government regulatory structures that balance mineral development objectives with environmental considerations. The survey also shows developing regulatory systems (some embryonic, some more mature) utilizing a combination of mining and environmental acts, and often an 'insider' perspective of the national officials administering the laws. While that perspective is not without its biases (not least the rigor of enforcement), it may nevertheless be of use in company planning. The emerging regulatory picture contradicts the conventional notion that it is the 'lower' level of regulation in Asia that is attracting foreign direct investment in mining. (author)

    We explore how the analysis of web-based data, such as Twitter and Google Trends, can be used to assess the social relevance of an environmental accident. The concept and methods are applied in the shutdown of drinking water supply at the city of Toledo, Ohio, USA. Toledo's notice, which persisted from August 1 to 4, 2014, is a high-profile event that directly influenced approximately half a million people and received wide recognition. The notice was given when excessive levels of microcystin, a byproduct of cyanobacteria blooms, were discovered at the drinking water treatment plant on Lake Erie. Twitter mining results illustrated an instant response to the Toledo incident, the associated collective knowledge, and public perception. The results from Google Trends, on the other hand, revealed how the Toledo event raised public attention on the associated environmental issue, harmful algal blooms, in a long-term context. Thus, when jointly applied, Twitter and Google Trend analysis results offer complementary perspectives. Web content aggregated through mining approaches provides a social standpoint, such as public perception and interest, and offers context for establishing and evaluating environmental management policies. - The joint application of Twitter and Google Trend analysis to an environmental event offered both short and long-term patterns of public perception and interest on the event

    This study focused on the survey for environmental impacts and hazard occurred in the abandoned metallic mines and their countermeasures. Major issues in the inactive metal mines were mine drainage, tailings, waste rock dump, abandoned facilities, in which acid mine drainage was a principal factor to deteriorate the environment around the abandoned mines. Chemical analysis shown that mine drainage was very acidic and were very acidic and were contaminated by toxic elements such as As, Pb, Cd, Mn, Fe, Cu and S etc. In addition, soil near the tailings impoundment was contaminated by heavy metals such as As, Pb, Cd, and cyanide. An column test was carried out to develop the passive treatment system for amelioration of the acid mine drainage with heavy metals. The experimental results revealed that composite mixed with the saw dust and cow manure was evaluated as the best substrate to have good permeability and to have enough food necessary for sulfate reduction bacteria. Small scaled anoxic wetland had been operated to confirm the capabilities of acid mine drainage treatment. The demonstration of the system revealed that the system neutralized acid mine drainage and also eliminated some metals such as Fe, Al, Mn, Cu, Cd, Pb and Zn etc up to by 98%.

    2013-01-01

    Full Text Available Background: Environmentally acquired asbestos-related diseases (ARDs are of concern globally. In South Africa, there is widespread contamination of the environment due to historical asbestos mining operations that were poorly regulated. Although the law makes provision for the compensation of occupationally acquired ARDs, compensation for environmentally acquired ARDs is only available through the Asbestos Relief Trust (ART and Kgalagadi Relief Trust, both of which are administered by the ART. This study assessed ARDs and compensation outcomes of environmental claims submitted to the Trusts. Methods: The personal details, medical diagnoses, and exposure information of all environmental claims considered by the Trusts from their inception in 2003 to April 2010 were used to calculate the numbers and proportions of ARDs and compensation awards. Results: There were 146 environmental claimants of whom 35 (23.9% had fibrotic pleural disease, 1 (0.7% had lung cancer, and 77 (52.7% had malignant mesothelioma. 53 (36.3% claimants were compensated: 20 with fibrotic pleural disease and 33 with mesothelioma. Of the 93 (63.7% claimants who were not compensated, 33 had no ARDs, 18 had fibrotic pleural disease, 1 had lung cancer, and 44 had mesothelioma. In addition to having ARDs, those that were compensated had qualifying domestic (33; 62.2% or neighbourhood (20; 37.8% exposures to asbestos. Most of the claimants who were not compensated had ARDs but their exposures did not meet the Trusts’ exposure criteria. Conclusions: This study demonstrates the environmental impact of asbestos mining on the burden of ARDs. Mesothelioma was the most common disease diagnosed, but most cases were not compensated. This highlights that there is little redress for individuals with environmentally acquired ARDs in South Africa. To stop this ARD epidemic, there is a need for the rehabilitation of abandoned asbestos mines and the environment. These issues may not be unique to

    The purpose of this report is to evaluate, in terms of cost and effectiveness, the various environmental control technologies that would be used to control the radioactive wastes generated in the mining, milling, and refining of thorium from domestic resources. The technologies, in order to be considered for study, had to reduce the radioactivity in the waste streams to meet Atomic Energy Commission (10 CFR 20) standards for natural thorium's maximum permissible concentration (MPC) in air and water. Further regulatory standards or licensing requirements, either federal, state, or local, were not examined. The availability and cost of producing thorium from domestic resources is addressed in a companion volume. The objectives of this study were: (1) to identify the major waste streams generated during the mining, milling, and refining of reactor-grade thorium oxide from domestic resources; and (2) to determine the cost and levels of control of existing and advanced environmental control technologies for these waste streams. Six potential domestic deposits of thorium oxide, in addition to stockpiled thorium sludges, are discussed in this report. A summary of the location and characteristics of the potential domestic thorium resources and the mining, milling, and refining processes that will be needed to produce reactor-grade thorium oxide is presented in Section 2. The wastes from existing and potential domestic thorium oxide mines, mills, and refineries are identified in Section 3. Section 3 also presents the state-of-the-art technology and the costs associated with controlling the wastes from the mines, mills, and refineries. In Section 4, the available environmental control technologies for mines, mills, and refineries are assessed. Section 5 presents the cost and effectiveness estimates for the various environmental control technologies applicable to the mine, mill, and refinery for each domestic resource

    Full Text Available Sustainability and corporate governance issues are now considered to be important and integral aspects of company performance. Both have established themselves as well-studied topics in the organisational and accountability areas. While there has been a growing interest to study the relationship between these two areas, research publication in this topic is still mainly focused on the Western societies. This study focuses on the corporate governance and sustainability disclosure practices in one of the emerging economies, Indonesia, and assesses the relationships between corporate governance variables and the extent of environmental disclosures made by the mining companies listed in the Indonesia Stock Exchange (IDX in their annual reports. The main findings of this study show that the extent of environmental disclosure made by these companies was moderate, and that there is a significant positive relationship between the size of board of directors and the extent of environmental disclosure.

    The uranium mining industry began its development in Argentina in the fifties. Since then, several installations have operated as uranium underground mining until late seventies, when that mines were closed. Since then, open pit exploitation has been used. Milling facilities were installed in the mining areas or close to them. The environmental radiological surveillance and the impact assessment presented in this work are referred to the uranium ore mining and milling plants Tonco, in Salta province; Pichinan, in Chubut province; San Rafael and Malargue, in Mendoza province; Los Gigantes, in Cordoba province; La Estela, in San Luis province and Los Colorados in La Rioja province. The environmental radiological surveillance programme results carried out from the beginning of the operations are presented and include uranium and radium concentrations in surface waters and sediments. The results obtained in waters upstream and downstream the uranium mining complexes are compared and no significant differences were observed. Moreover, taking into consideration the critical exposition pathways of the population living in the area, no significant levels of exposition were observed. (author)

  18. Environmentalism and natural aggregate mining

    Science.gov (United States)

    Drew, L.J.; Langer, W.H.; Sachs, J.S.

    2002-01-01

    Sustaining a developed economy and expanding a developing one require the use of large volumes of natural aggregate. Almost all human activity (commercial, recreational, or leisure) is transacted in or on facilities constructed from natural aggregate. In our urban and suburban worlds, we are almost totally dependent on supplies of water collected behind dams and transported through aqueducts made from concrete. Natural aggregate is essential to the facilities that produce energy-hydroelectric dams and coal-fired powerplants. Ironically, the utility created for mankind by the use of natural aggregate is rarely compared favorably with the environmental impacts of mining it. Instead, the empty quarries and pits are seen as large negative environmental consequences. At the root of this disassociation is the philosophy of environmentalism, which flavors our perceptions of the excavation, processing, and distribution of natural aggregate. The two end-member ideas in this philosophy are ecocentrism and anthropocentrism. Ecocentrism takes the position that the natural world is a organism whose arteries are the rivers-their flow must not be altered. The soil is another vital organ and must not be covered with concrete and asphalt. The motto of the ecocentrist is "man must live more lightly on the land." The anthropocentrist wants clean water and air and an uncluttered landscape for human use. Mining is allowed and even encouraged, but dust and noise from quarry and pit operations must be minimized. The large volume of truck traffic is viewed as a real menace to human life and should be regulated and isolated. The environmental problems that the producers of natural aggregate (crushed stone and sand and gravel) face today are mostly difficult social and political concerns associated with the large holes dug in the ground and the large volume of heavy truck traffic associated with quarry and pit operations. These concerns have increased in recent years as society's demand for

    1978-01-01

    The draft concerns the proposed issuance of approvals, permits, and licenses to the Homestake Mining Company for the implementation of the Pitch Project. The Pitch Project consists of mining and milling operations involving uranium ore deposits located in Gunnison National Forest, Saguache County, Colorado. Mining of uranium ore will take place over an estimated period of 20 years; a mill with a nominal capacity of 544 metric tons per day (600 tons per day) will be constructed and operated as long as ore is available. The waste material (tailings) from the mill, also produced at a rate of about 544 metric tons per day (600 tons per day), will be buried onsite at the head end of a natural valley. The environmental impacts are summarized in sections on the existing environment, applicant's proposed mining and milling operation, environmental effects of accidents, monitoring programs, productivity, commitment of resources, alternatives, and cost-benefit evaluation

  20. Mining and sustainable development: Considerations for minerals supply

    International Nuclear Information System (INIS)

    Lambert, Ian B.

    2001-01-01

    Sustainable development involves meeting the needs of human societies while maintaining viable biological and physical Earth systems. The needs include minerals: metals, fuels, industrial and construction materials. There will continue to be considerable demand for virgin mineral resources, even if levels of recycling and efficiency of use are optimal, and rates of population growth and globalisation decrease significantly. This article aims to stimulate debate on strategic issues for minerals supply. While the world has considerable stocks of mineral resources overall, international considerations of the environmental and social aspects of sustainable development are beginning to result in limitations on where mining will be conducted and what types of deposits will be mined. Current and emerging trends favour large mines in parts of the world where mining can be conducted within acceptable limits of environmental and social impact. Finding new deposits that meet such criteria will be all the more challenging given a disturbing global decline in the rate of discovery of major economic resources over the last decade, and the decreasing land area available for exploration and mining. To attract responsible exploration and mining, governments and mining nations will need to provide: regional-scale geo-scientific datasets as required to attract and guide future generations of exploration; resource access through multiple and sequential land use regimes, and frameworks for dealing with indigenous peoples' issues; and arrangements for consideration of mining proposals and regulation of mines that ensure responsible management of environmental and social issues. The minerals industry will need to continue to pursue advances in technologies for exploration, mining, processing, waste management and rehabilitation, and in public reporting of environmental and social performance.

  1. Drainage from coal mines: Chemistry and environmental problems

    International Nuclear Information System (INIS)

    Wildeman, T.

    1991-01-01

    Much of the research on coal-mine drainage chemistry was conducted a decade ago, and now increased environmental awareness has brought about renewed interest in the findings. Consideration of the trace minerals and elements in coal points to the possible generation of acidic waters upon weathering, especially when pyrite is present. When pyrite weathers, it produces H + and Fe 3+ which catalyze the incongruent weathering of other carbonates and sulfides. In this weathering mechanism, catalysis by bacteria is important. Of the environmental problems in coal mine drainage, the mineral acidity of the water is the most serious. This is caused not only by the H + , but also by Mn 4+ , Fe 3+ , and Al 3+ that are found or generated within the drainage. Case studies in Kentucky, Pennsylvania, Illinois, and Colorado show that the abundance and form of pyrite in the deposit and in the overburden determines the level of acidity and the concentration of heavy metal pollutants in the drainage. Recent trends in environmental enforcement that emphasize integrated stream water standards and biotoxicity assays point to the possibility that the concentrations of heavy metals in coal mine drainages may cause environmental concern

  2. Incorporating ecosystem services into environmental management of deep-seabed mining

    Le, Jennifer T.; Levin, Lisa A.; Carson, Richard T.

    2017-03-01

    Accelerated exploration of minerals in the deep sea over the past decade has raised the likelihood that commercial mining of the deep seabed will commence in the near future. Environmental concerns create a growing urgency for development of environmental regulations under commercial exploitation. Here, we consider an ecosystem services approach to the environmental policy and management of deep-sea mineral resources. Ecosystem services link the environment and human well-being, and can help improve sustainability and stewardship of the deep sea by providing a quantitative basis for decision-making. This paper briefly reviews ecosystem services provided by habitats targeted for deep-seabed mining (hydrothermal vents, seamounts, nodule provinces, and phosphate-rich margins), and presents practical steps to incorporate ecosystem services into deep-seabed mining regulation. The linkages and translation between ecosystem structure, ecological function (including supporting services), and ecosystem services are highlighted as generating human benefits. We consider criteria for identifying which ecosystem services are vulnerable to potential mining impacts, the role of ecological functions in providing ecosystem services, development of ecosystem service indicators, valuation of ecosystem services, and implementation of ecosystem services concepts. The first three steps put ecosystem services into a deep-seabed mining context; the last two steps help to incorporate ecosystem services into a management and decision-making framework. Phases of environmental planning discussed in the context of ecosystem services include conducting strategic environmental assessments, collecting baseline data, monitoring, establishing marine protected areas, assessing cumulative impacts, identifying thresholds and triggers, and creating an environmental damage compensation regime. We also identify knowledge gaps that need to be addressed in order to operationalize ecosystem services

    The underwater mining has increased in the recent years and the growing awareness of the potential impacts on the environment, as results of increasing the encroachment on the marine environment. Therefore, the debate has increased about how to protect this environment by using the scientific research thats relevant to the various environmental effects and developing the equipment used in dredging. There is a wide diversity of underwater mining equipments, such as continuous and non-continuous dredging which used for production of sand, gravel, alluvial deposits and raw material. There are a relation between increasingly dredging activities in the recent years and their impacts on the aquatic environment. These impacts are causes by changes in the topography of the sea floor such as turbidity, noise and other environmental impacts. Today, there is an international framework of legislation which has been developed for dredging projects. This contains rules and regulations which must be followed by mining companies and have to implemented by national authorities. The European countries also develop their legislation to control on the dredged material which deposit on land and sea. This legislation is constantly changing related to scientific knowledge and increasing the implementation frameworks. Also, the people become more sensitive to emissions that have a negative attitude towards dredging in the neighborhood. In addition, dredging techniques give rise to objections, which eventually led to think in more environmentally-friendly production methods. After that, the use of dredger is the only alternative in some project. The question is what are the true benefits of these techniques and what is the relation between possible improvements and technological potential as well as the costs. Therefore, it is intended to assess mining techniques in the context of their environmental impact and the costs. There are many systematic approaches which have been used for

    1999-01-01

    This report on 'Environmental Activities in Uranium Mining and Milling' presents an overview of environmental activities related to uranium production. The profile of activities and concerns are based on survey responses from 29 countries and a review of relevant activities of the International Atomic Energy Agency and the OECD Nuclear Energy Agency. It also provides an overview of the reported interests of specialists working in the field, including environmental impact assessment, emissions to air and water, work environment, radiation safety, waste handling and disposal, mine and mill decommissioning and site restoration, and the regulation of these activities. The report reflects the increasing awareness in all countries of the need for environmental protection. For several years large programmes have been underway in several countries to clean up wastes from closed mines and mills. Many of these sites, particularly the older ones, were brought into production, operated and closed when little was known about environmental effects. At the time, little concern was given to the resulting environmental impacts. Currently, planning for and conducting uranium mine closure and mill decommissioning, together with site clean-up and restoration, are of almost universal concern. Mine closure and mill decommissioning activities have been or are being conducted in most of the countries with a history of uranium production. Information about several mine closures and mill decommissioning projects is included in this report

    Canada introduced and environmental assessment process in the mid 1970s. It was designed to ensure that the environmental consequences of all project proposals with federal government involvement were assessed for potential adverse effects early in the planning stage. In 1984, a Guidelines Order was approved to clarify the rules, responsibilities and procedures of the environmental Assessment and Review Process (EARP) that had evolved informally under earlier Cabinet directives. In 1989/1990, the Federal Court of Appeal effectively converted the Guidelines Order into a legal requirement for rigorous application. The Supreme Court of Canada upheld the constitutionally of the EARP Guidelines Order in 1992. Canada became the world's leading producer and exporter of uranium during the late 1980s. Since then, the Canadian public has become sensitized to numerous issues concerning environmental degradation, from the Chernobyl accident to ozone depletion. In 1991, during this period of increasing awareness, the Atomic Energy Control Board, the federal nuclear regulator, referred six new Saskatchewan uranium mining projects for environmental review, pursuant to the EARP Guidelines Order. The public review process provided an extremely valuable focus on aspects of these developments that needed to be addressed by proponents and regulators. It has helped to demonstrate that new uranium mining projects are being developed in a responsible manner, after full consideration has been given to the potential impacts and public concerns associated with these facilities. 4 figs, 1 tab

    The objective of these guidelines is to accelerate environmental protection in peat mining and to reduce the harmful effects caused by its related activities. The guidelines promote achievement of environmental objectives set both in legislation and government programmes through uniform practices and interpretations. The guidelines are based on current valid legislation. The guidelines provide up-to-date information on best practices in peat mining, especially in water protection but also in reducing noise and dust. They are intended to ease the work of both peat producers and the licensing and controlling authorities. The guidelines are not legally binding and must be applied on case-by-case basis.

    Portmán Bay is a heavily contaminated area resulting from decades of metal mine tailings disposal, and is considered a suitable shallow-water analogue to investigate the potential ecotoxicological impact of deep-sea mining. Resuspension plumes were artificially created by removing the top layer of the mine tailings deposit by bottom trawling. Mussels were deployed at three sites: i) off the mine tailings deposit area; ii) on the mine tailings deposit beyond the influence from the resuspension plumes; iii) under the influence of the artificially generated resuspension plumes. Surface sediment samples were collected at the same sites for metal analysis and ecotoxicity assessment. Metal concentrations and a battery of biomarkers (oxidative stress, metal exposure, biotransformation and oxidative damage) were measured in different mussel tissues. The environmental hazard posed by the resuspension plumes was investigated by a quantitative weight of evidence (WOE) model that integrated all the data. The resuspension of sediments loaded with metal mine tails demonstrated that chemical contaminants were released by trawling subsequently inducing ecotoxicological impact in mussels' health. Considering as sediment quality guidelines (SQGs) those indicated in Spanish action level B for the disposal of dredged material at sea, the WOE model indicates that the hazard is slight off the mine tailings deposit, moderate on the mine tailings deposit without the influence from the resuspension plumes, and major under the influence of the resuspension plumes. Portmán Bay mine tailings deposit is a by-product of sulphide mining, and despite differences in environmental setting, it can reflect the potential ecotoxic effects to marine fauna from the impact of resuspension of plumes created by deep-sea mining of polymetallic sulphides. A similar approach as in this study could be applied in other areas affected by sediment resuspension and for testing future deep-sea mining sites in

    Full Text Available Sustainable mining management is increasingly seen as an important issue in achieving a social license to operate for mining companies. This study describes the life cycle cost (LCC analysis and environmental valuation for several coal mine tailings management scenarios. The economic feasibility of six different options was assessed using the Net Present Value (NPV and Benefit-Cost Analysis (BCA methods. These options were belt press (OPT 1, tailings paste (OPT 2, thickened tailings (OPT 3, and OPT 1 with technology improvement and renewable energy sources (OPT 1A-C. The results revealed that OPT 1A (belt press technology with stack cell flotation was the first preference in terms of LCC while OPT 1C (belt press technology with stack cell flotation and 10% wind energy generated the highest benefits value (BCA compared to the other options. The LCC and BCA components and the volume of GHG emissions were used to determine the best option. Normalization of these three elements resulted in the selection of Option 1C as being the most cost-effective option.

    2017-07-01

    Full Text Available The purpose of this study was to explore the effective method of the comprehensive evaluation of ecological environmental quality in a coal mining area. Firstly, we analyzed the ecological environmental effect of the coal mining area according to Pigovian Tax theory and, according to the results of the analysis and the demand for the selection of evaluation indices by the comprehensive evaluation, built the corresponding comprehensive evaluation index system. We then used the correlation function method to determine the relative weights of each index. We determined the basic standards of a comprehensive evaluation of ecological environmental quality in a coal mining area according to the actual situation of ecological environmental quality assessments in coal mining areas in our country and the relevant provisions of the government. On this basis, we built the two-level extension comprehensive evaluation model for the evaluation of ecological environmental quality in mining areas. Finally, we chose a certain coal mining area of Yanzhou Coal Mining Company Limited as the specific case. We used the relevant statistic data, technical and economic indices and the extension evaluation model to do the applied research of the comprehensive evaluation and tested the effectiveness of the comprehensive evaluation model.

    2014-12-01

    Full Text Available The Chinese government adopted more specific and stringent environmental impact assessment (EIA guidelines in 2011, soon after the widespread ethnic protests against coal mining in Inner Mongolia. However, our research suggests that the root of the ethnic tension is a sustainability problem, in addition to environmental issues. In particular, the Mongolians do not feel they have benefited from the mining of their resources. Existing environmental assessment tools are inadequate to address sustainability, which is concerned with environmental protection, social justice and economic equity. Thus, it is necessary to develop a sustainability impact assessment (SIA to fill in the gap. SIA would be in theory and practice a better tool than EIA for assessing sustainability impact. However, China’s political system presents a major challenge to promoting social and economic equity. Another practical challenge for SIA is corruption which has been also responsible for the failing of EIA in assessing environmental impacts of coal mining in Inner Mongolia. Under the current political system, China should adopt the SIA while continuing its fight against corruption.

    The National Atomic Energy Commission (CNEA) started its activities 50 years ago and obtained significant results. At the present time, the CNEA is defined as an Institution of research and development in the nuclear field. It is also responsible for the management of radioactive wastes and the dismantling of nuclear and radioactive facilities. Mining and milling activities have been carried out during the past 40 years and at present the CNEA is undertaking the Uranium Mining Environmental Restoration Project (PRAMU). The aim of this project is to restore the environment as much as is possible in all places where uranium mining and milling activities were developed when taking into consideration both economic and technical reality. First, the characteristics of the problems in each site are determined through appropriate studies which identify the existing or potential impacts, the possible pathways of contamination, etc. The sites being studied are: MALARGUE (Mendoza Province), CORDOBA (Cordoba Province), LOS GIGANTES (Cordoba Province), HUEMUL (Mendoza Province), PICHINAN (Chubut Province), TONCO (Salta Province), LA ESTELA (San Luis Province), LOS COLORADOS (La Rioja Province). PRAMU seeks to improve the current conditions of the tailings deposits and mines and to ensure the long term protection of people and the environment. The CNEA is required to comply with all legislation that is in force and is under the control of various national, provincial and local State institutions. The main objectives of the project for the various sites are: (a) Malargue site: to implement the actions necessary for environmental restoration and management of the tailings derived from the uranium ores processed in the industrial plant; (b) Cordoba and Los Gigantes sites: to design, engineer and execute the activities required for closure of the sites; (c) Other sites (Huemul, Pichinan, Tonco, La Estela, Los Colorados): to develop an environmental evaluation and, on the basis of

    1991-01-01

    The environmental policy in the Netherlands, as outlined in the National Environmental Policy Plan, aims for a sustainable development. In principle a two track approach is adhered to: source oriented as well as effects oriented. Effects oriented policy includes the setting of environmental quality objectives and is used to establish the final goals for the source-oriented measures. The policy aims at integrated life-cycle management; in the final target situation all waste is used again as raw material and remaining emissions to the environment should comply with the environmental objectives. In this paper the implications of this policy for the offshore mining industry are elaborated, both for drilling operations and for the production of oil, gas and condensate. The results of the recently concluded Environmental Impact Assessment for the offshore mining industry as a whole are also elaborated

    The environmental behavior of the residents depends on their perception of environmental pollution. Hence, it is important for scientific and policy experts to research on the impact of the environmental pollution perception of local residents. Owing to the richness of natural resources, Hancheng coal mine areas are abound in heavy industries, and environmental pollution is serious and typical in this area, thus, the residents are anxious about their health. Using questionnaires, this paper surveys the perception of residents living in the coal mine area. The influential factors of environmental perception were analyzed by the Rank Sum Test. The results were: (1) the majority of the residents in the coal mine area are not satisfied with their living environment. The perception order of pollution severity is: air pollution > noise pollution > sanitation > water pollution. The residents think that pollution is mainly caused by coal processing. Hence, coal mining is not the main reason of the pollution in the coal mine area. (2) Age and length of residence have significant positive effects on perceptions of air, water, and noise pollutions; whereas education has a significant negative effect on perceptions of water and noise pollutions, as well as sanitation. This phenomenon can be explained by the various cultural groups having varied perceptions on the environmental pollution. In addition, proximity to mine has significant negative effect on perceptions of water and noise pollution. In conclusion, the paper discusses the effects of demographical and social factors on the perception of environmental pollution and gives suggestions on the planning and management of the environment.

    Mined repositories present an environmentally viable option for permanent disposal of nuclear waste. This paper reviews the state-of-the-art mining technologies and identifies technological issues and developments necessary to mine a repository in basalt. The thermal loading, isolation, and retrieval requirements of a repository present unique technological challenges unknown to conventional mining practice. The technology issues and developments required in the areas of excavation, roof and ground support, equipment development, instrumentation development, and sealing are presented. Performance assessment methods must be developed to evaluate the adequacies of technologies developed to design, construct, operate, and decommission a repository. A stepwise test-and-development approach is used in the Basalt Waste Isolation Project to develop cost-effective technologies for a repository

    Zyl, H.C. van

    1997-01-01

    The impact of Amcoal collieries on the environment is assessed and recorded in great detail in the Environmental Management Programme Reports. Before mining authorization is granted by the Department of Mineral and Energy Affairs, each mine is required by the Minerals Act of 1991 to develop an EMPR in consultation with the departments of Mineral and Energy Affairs, Water Affairs, Environment Affairs, Agriculture, and Nature Conservation, as well, as parties that are or may be affected by the mining operations. The effects mining has or will have on the topography, geology, soils, vegetation, animal life, surface and ground water, cultural resources, and the socio-economy are assessed for each mine. Detailed plans concerning how these impacts will be prevented, minimized or ameliorated are recorded in the EMPRs. Commitments made and recorded in an EMPR are legally binding. They include details of financial mechanisms required to guarantee final rehabilitation, closure and after-care of mine sites. Through experience and involvement in a broad spectrum of environmental management issues, Amcoal has nurtured environmental awareness among its staff and a commitment to excellence in environmental management. It has developed the capability and capacity to respond to current and future environmental challenges. Progress has been made in addressing environmental issues at the mines in a systematic and comprehensive manner. As well as improving the situation at mine level, these efforts will also contribute to maintaining regional land use capabilities and river quality

    2013-11-01

    The environmental impact assessment of mining sites represents nowadays a large interest topic in Romania. Historical pollution in the Rosia Montana mining area of Romania caused extensive damage to environmental media. This paper has two goals: to investigate the environmental pollution induced by mining activities in the Rosia Montana area and to quantify the environmental impacts and associated risks by means of an integrated approach. Thus, a new method was developed and applied for quantifying the impact of mining activities, taking account of the quality of environmental media in the mining area, and used as case study in the present paper. The associated risks are a function of the environmental impacts and the probability of their occurrence. The results show that the environmental impacts and quantified risks, based on quality indicators to characterize the environmental quality, are of a higher order, and thus measures for pollution remediation and control need to be considered in the investigated area. The conclusion drawn is that an integrated approach for the assessment of environmental impact and associated risks is a valuable and more objective method, and is an important tool that can be applied in the decision-making process for national authorities in the prioritization of emergency action.

  13. Environmental impact of solution mining for uranium

    International Nuclear Information System (INIS)

    Hunkin, G.G.

    1975-01-01

    Compared with most other mining systems, uranium solution mining has a negligible effect on such environmental factors as surface disturbance, interference with natural groundwater quality and distribution, and aerial discharge of radionuclides. The following topics are discussed: the process, personnel safety and health, tailings disposal, impact on groundwater, operating licenses and controls, legislation, and economics. It is concluded that engineered well systems and controlled input/production flow rates, combined with full recirculation systems that maintain constant fluid volumes in the mineralized formations, result in containment of leach solutions within the operating area. The very dilute leach solutions, compatible with natural groundwaters, ensure that no environmental damage results, even if a loss of control occurred. Reduction in the number of processing steps and virtual elimination of operator hazards, waste disposal and land rehabilitation costs help in reducing overall costs

    1998-01-01

    Abandoned Mined Lands (AML) are lands that were mined prior to implementation of the federal Surface Mining Control and Reclamation Act (SMCRA) in 1977, but were inadequately reclaimed. Re-mining of AML is being conducted on a routine basis by coal-mining operations in eastern states such as Virginia. Re-mining is a potentially important means of reclaiming AML. However, under current policies, re-mining operations often fail to permit and reclaim priority 1, 2, and 3 AML, especially those areas which present the most severe environmental problems. This paper describes policy issues which affect the potential for AML reclamation by re-mining operations in mountainous mining areas, such as Virginia; efforts underway in Virginia which seek to resolve those issues; and progress achieved to date under that initiative

It outlines personnel qualification and commitment, actions and policy in the field of personnel health and safety. It addresses the environmental policy: key levers, environmental management system, examples throughout the entire mining life cycle, changes in site consumptions and emissions, promotion of biodiversity. The next part concerns Areva's social commitment (dialogue, development aid in mining territories). Then, performance is expressed in terms of indicators for these different issues (teams, environmental policy, social involvement)

  16. The environmental impact of mine wastes - roles of microorganisms and their significance in treatment of mine wastes

    International Nuclear Information System (INIS)

    Ledin, M.; Pedersen, K.

    1996-01-01

    Mine wastes constitute a potential source of contamination to the environment, as heavy metals and acid are released in large amounts. A great variety of microorganisms has been found in mine wastes and microbiological processes are usually responsible for the environmental hazard created by mine wastes. However, microorganisms can also be used to retard the adverse impact of mine wastes on the environment. Conventionally, the mine drainage as well as the waste itself can be treated with alkali to increase pH and precipitate metals. The main drawback of this method is that it has to be continuously repeated to be fully effective. There may also be negative effects on beneficial microorganisms. Several other treatment methods have been developed to stop weathering processes thereby reducing the environmental impact of mine wastes. The other main approach is to treat the drainage water. Various methods aim at using microorganisms for this in natural or engineered systems. Recently, much interest has been focused on the use of natural or artificial wetlands for treatment. In general, the activity of microorganisms is neglected in the design of mine waste treatment systems, and the treatments are created merely from a technical point of view. This can result in situations where unexpected microbial processes take over, and, in the worst scenario, the overall effect is opposite to the desired

    Lee, M. J.; Oh, K. Y.; Joung-ho, L.

    2016-12-01

    Recently there are many research about analysing the interaction between entities by text-mining analysis in various fields. In this paper, we aimed to quantitatively analyse research-trends in the area of environmental research relating either spatial information or ICT (Information and Communications Technology) by Text-mining analysis. To do this, we applied low-dimensional embedding method, clustering analysis, and association rule to find meaningful associative patterns of key words frequently appeared in the articles. As the authors suppose that KCI (Korea Citation Index) articles reflect academic demands, total 1228 KCI articles that have been published from 1996 to 2015 were reviewed and analysed by Text-mining method. First, we derived KCI articles from NDSL(National Discovery for Science Leaders) site. And then we pre-processed their key-words elected from abstract and then classified those in separable sectors. We investigated the appearance rates and association rule of key-words for articles in the two fields: spatial-information and ICT. In order to detect historic trends, analysis was conducted separately for the four periods: 1996-2000, 2001-2005, 2006-2010, 2011-2015. These analysis were conducted with the usage of R-software. As a result, we conformed that environmental research relating spatial information mainly focused upon such fields as `GIS(35%)', `Remote-Sensing(25%)', `environmental theme map(15.7%)'. Next, `ICT technology(23.6%)', `ICT service(5.4%)', `mobile(24%)', `big data(10%)', `AI(7%)' are primarily emerging from environmental research relating ICT. Thus, from the analysis results, this paper asserts that research trends and academic progresses are well-structured to review recent spatial information and ICT technology and the outcomes of the analysis can be an adequate guidelines to establish environment policies and strategies.

  20. Environmental audits: Tax, accounting and disclosure issues

    International Nuclear Information System (INIS)

    MacKnight, R.

    1991-01-01

    An overview is presented of the financial and legal issues associated with environmental audits, with an emphasis on tax issues. Accelerated depreciation write-offs are provided for qualified pollution control equipment, and may also qualify for tax credits. The Accounting Standards Committee recommends that provision should be made for future removal and site restoration costs and net of expected recoveries, in a rational and systematic manner by charges to income. Under the Federal Income Tax Act (ITA), future reclamation and shutdown costs will only be deductible if they pass three hurdles: a liability which requires the expenditure of funds in the future may not necessarily be an expense; if the liability can be viewed as an expense, is it incurred for the purpose of gaining or producing income; and is a deduction prohibited because it is on account of capital. A proposed solution to these problems is to adopt the US model that allows the deduction of estimated costs of reclaiming land that is disturbed during the current year at mines and waste disposal sites. Tax treatment of compliance costs, securities law disclosure, proposed federal government policies, proposed regulatory measures, and proposed fiscal measures are discussed

    Full Text Available Mining for resources extraction may lead to geological and associated environmental changes due to ground movements, collision with mining cavities, and deformation of aquifers. Geological changes may continue in a reclaimed mine area, and the deformed aquifers may entail a breakdown of substrates and an increase in ground water tables, which may cause surface area inundation. Consequently, a reclaimed mine area may experience surface area collapse, i.e., subsidence, and degradation of vegetation productivity. Thus, monitoring short-term landscape dynamics in a reclaimed mine area may provide important information on the long-term geological and environmental impacts of mining activities. We studied landscape dynamics in Kirchheller Heide, Germany, which experienced extensive soil movement due to longwall mining without stowing, using Landsat imageries between 2013 and 2016. A Random Forest image classification technique was applied to analyze land-use and landcover dynamics, and the growth of wetland areas was assessed using a Spectral Mixture Analysis (SMA. We also analyzed the changes in vegetation productivity using a Normalized Difference Vegetation Index (NDVI. We observed a 19.9% growth of wetland area within four years, with 87.2% growth in the coverage of two major waterbodies in the reclaimed mine area. NDVI values indicate that the productivity of 66.5% of vegetation of the Kirchheller Heide was degraded due to changes in ground water tables and surface flooding. Our results inform environmental management and mining reclamation authorities about the subsidence spots and priority mitigation areas from land surface and vegetation degradation in Kirchheller Heide.

  3. Analyzing the effect of Akoben programme on the environmental performance of mining in Ghana: A case study of a gold mining company

    Serwaa Akoto Bawua

    Full Text Available This study assessed the impact of Ghana's Environmental Protection Agency (EPA Akoben programme, a rating and disclosure tool which seeks to promote better environmental performance in the mining and manufacturing industries in Ghana. Using a case study approach, the Akoben audit report card for a mining company was analyzed over a three-year period (2009–2011 based on 7-criteria – legal requirements, hazardous on-site waste management, toxic emissions management, environmental monitoring and reporting, best practice environmental management, complaint management, and corporate social responsibility. Key stakeholders' perceptions of the programme's suitability were solicited from the Ghana Chamber of Mines, EPA, and the mining company. Findings revealed that overall environmental performance over the three-year period under review was poor (2009 – 56.6%; 2010 – 65.6%; 2011 – 59.1% with none of the years meeting the expected minimum limit, with the exception of legal requirements and corporate social responsibilities; the company failed in all other criteria. Specifically, both toxic and non-toxic waste emission discharges were major concerns as toxic parameters, such as for Arsenic, pH and Cyanide, were exceeded. Environmental monitoring and reporting was also a problem for the company. Stakeholders identified inadequate publicity, an absence of legal backing, and a lack of incentives for outstanding performances as the main weaknesses of the programme. Despite this, the stakeholders acknowledge the fact that the Akoben programme has improved the environmental performance of the mining companies because it puts their operations in check, although more can yet be achieved with regards environmental sustainability with this programme, if adequate measures including legal backing are put in place to ensure its continuity.

    In Argentina the National Atomic Energy Commission (CNEA) has the responsibility to restore uranium mining facilities, when milling operations have been shut down. To carry out this clean up actions CNEA created the Project for Uranium Mining Environmental Restoration (PRAMU in Spanish). To take into account the environmental aspects of the restoration activities, the PRAMU includes in its management an Environmental Management System (SGA in Spanish), which is of central importance in determining the environmental policy, objectives and targets. In this work a general view of the Environmental Management System is presented and an example of one of the environmental programs to be implemented is detailed. (author)

The previous generation of mines were approved under the former Environment Protection (Impact of Proposals) Act 1993 or earlier arrangements. In recent years various guidelines, both generic and developed for individual proposals have been issued by State, Territory and Federal governments. Recent Australian guidelines, for uranium and other mining, all include a risk-based approach to environmental impact assessment, including consideration of design and operating measures to minimize impacts, and associated environmental monitoring programmes to assess actual against expected outcomes and provide early-warning of potentially adverse trends. Some recent guidelines and their application to new uranium projects or extensions of existing operations in three jurisdictions are reviewed and the usefulness of the approach discussed. (author)

    The impact on global climate change from coal mine methane emissions in China has been drawing attention as coal production has powered its economic development. Data on coal mine methane emissions from the State Administration of Coal Mine Safety of China has been analyzed. It is estimated that the methane emission from coal mining in China reached 20 billions of cubic meters in 2008, most of which comes from state-owned coal mines with high-gas content. China releases six times as much of methane from coal mines as compared to the United States. However, Chinese methane emission from coal production accounts for only a very small proportion on the environmental impact when compared to emissions of carbon dioxide from fossil fuel consumption. The Chinese government has shown environmental awareness and resolution on the mitigation and utilization of coal mine methane emissions. Measures have been taken to implement the programs of mitigation and utilization of coal mine methane, and at the same time, to ensure mining safety. Nearly 7.2 billions of cubic meters of methane were drained from the coal mines, and 32% of it was utilized in 2008. The slow advancement of technologies for the drainage and utilization of low-concentration methane from ventilation air hinders the progress of mitigation of atmospheric methane and the utilization of coal mine methane emissions.

    Ranger Uranium Mine operates under an Authorisation issued by the Northern Territory Government. In addition, the site is regulated by a set of Environmental Requirements attached to the uranium export permit issued by the Australian Government Department of Resources, Energy and Tourism. A Heap Leach facility proposed for the site could result in a third approval being issued, in accordance with the Environmental Protection and Biodiversity Conservation Act 1999 (EPBC Act). Finding the correct balance to regulate the mine in light of these approvals will be a challenge for the range of stakeholders involved in regulation and oversight of this operation. (author)

    2016-08-01

    Under certain conditions landscape topography which utilizes mine tailing reservoir construction using is likely to increase lateral recharge source regions, resulting in dramatic changes to the local hydrological dynamic field and recharge of downstream areas initiated by runoff, excretion state, elevated groundwater depth, shallow groundwater, rainfall direct communication, and thinning of the vadose zone. Corrosive leaching of topsoil over many years of exposure to chemical fertilizers and pesticides may result in their dissolution into the groundwater system, which may lead to excessive amounts of many harmful chemicals, therby affecting the physical and mental health of human residents and increase environmental vulnerability and risk associated with the water and soil. According to field survey data from Yujiakan, Qian'an City, and Hebei provinces, this paper analyzes the hydrogeological environmental mechanisms of areas adjacent to mine tailing reservoirs and establishes a conceptual model of the local groundwater system and the concentration-response function between NO3 - content in groundwater and the incidence of cancer in local residents.

  11. International Symposium on Uranium Raw Material for the Nuclear Fuel Cycle: Exploration, Mining, Production, Supply and Demand, Economics and Environmental Issues. Presentations

    International Nuclear Information System (INIS)

    2014-01-01

    The long term sustainability of nuclear power will depend on, among several factors, an adequate supply of uranium resources that can be delivered to the marketplace at competitive prices. New exploration technologies and a better understanding of the genesis of uranium ores will be required to discover often deep-seated and increasingly hard to find uranium deposits. Exploration, mining and milling technologies should be environmentally benign, and site decommissioning plans should meet the requirements of increasingly stringent environmental regulations and societal expectations. The purpose of this symposium is to analyse uranium supply–demand scenarios and to present and discuss new developments in uranium geology, exploration, mining and processing, as well as in environmental requirements for uranium operations and site decommissioning. The presentations and discussions at URAM-2014 will: - Lead to a better understanding of the adequacy of uranium sources (both primary and secondary) to meet future demand; - Provide information on geological models, new exploration concepts, knowledge and technologies that will potentially lead to the discovery and development of new uranium resources; - Describe new production technologies that have the potential to more efficiently and sustainably develop new uranium resources; and - Document the environmental compatibility of uranium production and the overall effectiveness of progressive final decommissioning and, where required, remediation of production facilities.

    Full Text Available The present article attempts to analyze methods that can be used to restore a former coal mining site to a condition that is well integrated into its surroundings and that recovers the abandoned and contaminated land and renders its value to the community. The key concept that guides the present paper is that the coal mining is just a temporary land use and that the cost of cleaning the mining site should be an operating expense that has to be included in the budget of a coal mine company starting with the first year of operation. The coal mining industry in Romania is presented as a case study to emphasize the effects that closed coal mines have on communities where they are located and, based on the methods that are successfully used to solve similar problems, recommendations are formulated to improve the environmental rehabilitation of the mining sites.

The multicriteriality is considered as the crucial principle of rational subsoil use at taking management decisions, i.e. the considering of ecological, economic and social targets, aimed at receiving moderate profit at proper social and environmental standards. The graphic representation of models of the general mining approach and the alternative one allows to emphasize the specified advantages of transition to rational subsoil resources development and reflect them in design equation. In the paper, three performance strategies providing the implementation of the alternative approach are offered: full-field development, application ecologically and economically effective systems and the development processes, consideration of reclamation and minimization of long term environmental effects of mining

    An environmental radiological surveillance programme has been in progress around the most significant Portuguese uranium mines, from 1976 to 1983. A short description is given of the mines of Urgeirica (including uranium milling), Freixiosa, Pinhal de Souto and Bica. The results of the surveillance programme developed in the vicinity of these facilities are presented and the identified critical pathways are discussed. One of these pathways is the consumption of cabbage, which is an important component in the diet of the Portuguese population. The exposure of the critical groups, due to the intake of 226 Ra through the diet, calculated from the results of this monitoring programme, range from 0.02 to 1.5 mSv.y -1 for the different mines under study.

    In November 2015, a large mine-tailing dam owned by Samarco Corporation collapsed in Brazil, generating a massive wave of toxic mud that spread down the Doce River, killing 20 people and affecting biodiversity across hundreds of kilometers of river, riparian lands, and Atlantic coast. Besides the disaster's serious human and socioeconomic tolls, we estimate the regional loss of environmental services to be ~US$521 million per year. Although our estimate is conservative, it is still six times higher than the fine imposed on Samarco by Brazilian environmental authorities. To reduce such disparities between estimated damages and levied fines, we advocate for an environmental bond policy that considers potential risks and environmental services that could possibly be impacted by irresponsible mining activity. Environmental bonds and insurance are commonly used policy instruments in many countries, but there are no clear environmental bond policies in Brazil. Environmental bonds are likely to be more effective at securing environmental restitution than post-disaster fines, which generally are inadequate and often unpaid. We estimate that at least 126 mining dams in Brazil are vulnerable to failure in the forthcoming years. Any such event could have severe social-environmental consequences, underscoring the need for effective disaster-management strategies for large-scale mining operations. © 2016 by the Ecological Society of America.

    1994-12-01

    Half of Africa's almost 450 million inhabitants have no access to health services, while two-thirds lack safe drinking water, according to a 1991 report by the World Bank. Most Africans are also seriously affected by poverty, civil war, indoor and outdoor pollutants, diarrhea-causing microbes, tropical diseases such as malaria, rapid population growth, inadequate sanitation and sewage treatment, poor environmental management, corrupt government policies, desertification and deforestation, mining, and the overuse of pesticides and insecticides. Environmentally-related diseases compromise the continent's productivity, making it more difficult to generate revenue to fight the environmental health problems. Industrial pollutants remain rare, however, since almost 80% of sub-Saharan Africa remains pastoral or agro-pastoral. Even so, urbanization is exposing growing numbers of sub-Saharan Africans to hazardous and toxic wastes. Developing countries ship their most dangerous wastes to Africa because their own domestic environmental laws and the high costs of disposal make it difficult and expensive to dispose of them at home. The author discusses population growth in Africa; the lack of good data on the environment and health in Africa; infant and child mortality; water, sewage, and garbage; agriculture, mining, and industry; and sustainable development and the future.

    Sudbury is considered to be the centre of the Canadian mining industry and has gained a reputation for environmentally sound mining practices that are being met through mine site rehabilitation and regional land reclamation. This international conference provided a forum to exchange ideas and information pertinent to mine reclamation activities. More than 400 delegates, including leading scientists and technical experts from around the world participated at the conference. Approximately 150 papers were presented on a wide range of topics related to mine site rehabilitation issues and environmental protection methods associated with mining. Both current and future challenges faced by the mining industry were discussed with particular reference to the long-term sustainability of the mining process. Topics of discussion included issues pertaining to reclamation and rehabilitation of disturbed lands and waterways as well as specific site reclamation challenges associated with the oil industry. Reclamation activities include a wide range of expertise including plant ecology, forestry, soil science, land use planning, civil and mine engineering, wildlife biology, and reclamation. Six papers from the conference have been processed separately for inclusion in this database. refs., tabs., figs

    2012-06-01

    Full Text Available This paper draws on research conducted in the past two decades examining issues related to the human element in mine disasters. While much of the emergency response community employs a systems approach that takes into account psychosocial issues as they impact all aspects of an emergency, the mining industry has lagged behind in integrating this critical element. It is only within the past few years that behavioral interventions have begun to be seen as a part of disaster readiness and resiliency in the industry. The authors discuss the potential applications of psychosocial studies and suggest ways to improve mine emergency planning, psychological support, and decision-making during a response, as well as actions in the aftermath of incidents. Topics covered, among others, include an economic rationale for including such studies in planning a mine emergency response, sociological issues as they impact such things as leadership and rescue team dynamics, and psychological issues that have an effect on individual capacity to function under stress such as during escape, in refuge alternatives, and in body recovery. This information is intended to influence the mine emergency escape curriculum and impact actions and decision-making during and after a mine emergency. The ultimate goal is to mitigate the trauma experienced by individuals, the organization, and the community.

    Ground collapses over abandoned underground mines constitute a new environmental risk in the world. The high risk associated with subsurface voids, together with lack of knowledge of the geometric and geomechanical features of mining areas, makes abandoned underground mines one of the current challenges for countries with a long mining history. In this study, a stability analysis of Montevecchia marl mine is performed in order to validate a general approach that takes into account the poor local information and the variability of the input data. The collapse risk was evaluated through a numerical approach that, starting with some simplifying assumptions, is able to provide an overview of the collapse probability. The final results is an easy-accessible-transparent summary graph that shows the collapse probability. This approach may be useful for public administrators called upon to manage this environmental risk. The approach tries to simplify this complex problem in order to achieve a roughly risk assessment, but, since it relies on just a small amount of information, any final user should be aware that a comprehensive and detailed risk scenario can be generated only through more exhaustive investigations.

    2013-11-01

    On top of significant improvements and progress made through science and engineering in the last century to increase efficiency and reduce impacts of mining to the environment, risk assessment has an important role to play in further reducing such impacts and preventing and mitigating risks. This paper reflects on how risk assessment can improve planning, monitoring and management in mining and mineral processing operations focusing on the importance of better understanding source-pathway-receptor linkages for all stages of mining. However, in light of the ever-growing consumption and demand for raw materials from mining, the need to manage environmental resources more sustainably is becoming increasingly important. The paper therefore assesses how mining can form an integral part of wider sustainable resources management, with the need for re-assessing the potential of mining in the context of sustainable management of natural capital, and with a renewed focus on its the role from a systems perspective. The need for understanding demand and pressure on resources, followed by appropriate pricing that is inclusive of all environmental costs, with new opportunities for mining in the wastes we generate, is also discussed. Findings demonstrate the need for a life cycle perspective in closing the loop between mining, production, consumption and waste generation as the way forward.

    Mandatory insurance requirements and/or mitigation fees (royalties) for mining companies may help reduce environmental risk exposure for the federal government. Mining is examined since the Environmental Protection Agency (EPA) Toxic Release Inventory reveals that this sector produces more hazardous waste than any other industrial sector. Although uncommon, environmental expense can exceed hundreds of millions of dollars per development. Of particular concern is the potential for mines to become unfunded Superfund sites. Monte Carlo simulation of risk exposure is used to establish a plausible range of unfunded federal liabilities associated with cyanide-leach gold mining. A model is developed to assess these costs and their impact on both the federal budget and corporate profitability (i.e., industry sustainability), particularly if such costs are borne by offending firms.

The major aim of this paper is to investigate whether such practices have a close relationship with the mining firm’s financial performance (represented by return on equity [ROE]. The approach is a case study of a South African mining firm listed under the socially responsible index (SRI of the Johannesburg Stock Exchange (JSE. It uses Green-Steel sa (pseudonym used in place of the real name as a case study. Using multiple regression statistics, the return on equity of Green-Steel sa is regressed on three environmental management practices of Green- Steel (carbon reduction, energy efficiency, and water usage. The result shows there is no significant relationship between the variables and this lends credence to information gathered from Green-Steel environmental reports that Green-Steel’s environmental management practices are driven mostly by a desire to abide by regulations and also by a moral obligation to use environmental management practices to mitigate climate change impact.

    Air quality in the mining sector is a serious environmental concern and associated with many health issues. The air quality management in mining region has been facing many challenges due to lack of understanding of atmospheric factors and physical removal mechanism. A modeling approach called mining air dispersion model (MADM) is developed to predict air pollutants concentration in the mining region while considering the deposition effect. The model is taken into account through the planet's boundary conditions and assuming that the eddy diffusivity depends on the downwind distance. The developed MADM is applied to a mining site in Canada. The model provides values as the predicted concentrations of PM 10 , PM 2.5 , TSP, NO 2 and six heavy metals (As, Pb, Hg, Cd, Zn, Cr) at various receptor locations. The model shows that neutral stability conditions are dominant for the study site. The maximum mixing height is achieved (1280 m) during the evening of summer, and minimum mixing height (380 m) is attained during the evening of winter. The dust fall (PM coarse) deposition flux is maximum during February and March with the deposition velocity of 4.67 cm/s. The results are evaluated with the monitoring field values, revealing a good agreement for the target air pollutants with R-squared ranging from 0.72 to 0.96 for PM 2.5 ; 0.71 to 0.82 for PM 10 and from 0.71 to 0.89 for NO 2 . The analyses illustrate that presented algorithm in this model can be used to assess air quality for the mining site in a systematic way. The comparison of MADM and CALPUFF modeling values are made for four different pollutants (PM 2.5 , PM 10 , TSP, and NO 2 ) under three different atmospheric stability classes (stable, neutral and unstable). Further, MADM results are statistically tested against CALPUFF for the air pollutants and model performance is found satisfactory.

    Full Text Available Cleaner Production (CP addresses precautionary, site-specific environmental measures to reduce emissions and assess resource efficiency potentials at the point of origin by analyzing operational material and energy flows. The approach is generally based on the criteria quality as well as environmental/occupational health and safety, and promotes their integration. The paper presents options for applying CP to aggregate mining, based on a Life Cycle Assessment (LCA and illustrated by results from a study of small-scale industrial aggregate mining in Hoa Binh Province (Vietnam. The regulatory framework to limit the impact of mining on the environment is largely comparable to international standards and is suitably enforced. Despite gaining experience through the practical handling of enforcement procedures over the long term, there is still a considerable potential to optimize CP strategies in Vietnam’s aggregate mining industry. This is shown by the results of a survey of aggregates mining companies in Hoa Binh Province as well as on-site data collection to determine the technological characteristics of production facilities alongside economic and environmental factors. The assessment of the survey is supported by LCA results for: (a the existing situation; and (b the scenario of a merging of companies, undertaken to improve the resource efficiency of the aggregate mining in Hoa Binh. Findings can help implement an integrated approach to foster the sustainable mining of building aggregates.

  20. Waste management and environmental controls in the Australian uranium mining industry

    International Nuclear Information System (INIS)

    Walker, D.G.; Morison, I.W.

    1983-01-01

    An outline is given of the development of the waste management and related environmental controls currently applied to uranium mining and processing in Australia, reflecting three decades of experience. The Ranger Uranium Environmental Inquiry of the mid-1970s was, inter alia, a focus for the expression of public concerns over the environmental effects of uranium mining. The report of the Inquiry established a framework for controls over uranium mining in the Northern Territory and, by association, in other States of the Commonwealth. The interaction between Federal and State jurisdictions, and the establishment of Codes of Practice and their implications are briefly described. Current procedures are based on the experience of other countries but are much influenced by studies of the environmental impact of uranium production in Australia during the 1950s and 1960s. In addition, laboratory investigations have been made of specific processes, such as the impact of heavy metal contaminants on biota and the uptake of radium in the human food cycle. Such studies are continuing and research is being expanded, particularly in relation to Northern Territory developments. Australia is contributing the results of this work to appropriate international forums. (author)

  1. Uranium mining

    International Nuclear Information System (INIS)

    2008-01-01

    Full text: The economic and environmental sustainability of uranium mining has been analysed by Monash University researcher Dr Gavin Mudd in a paper that challenges the perception that uranium mining is an 'infinite quality source' that provides solutions to the world's demand for energy. Dr Mudd says information on the uranium industry touted by politicians and mining companies is not necessarily inaccurate, but it does not tell the whole story, being often just an average snapshot of the costs of uranium mining today without reflecting the escalating costs associated with the process in years to come. 'From a sustainability perspective, it is critical to evaluate accurately the true lifecycle costs of all forms of electricity production, especially with respect to greenhouse emissions, ' he says. 'For nuclear power, a significant proportion of greenhouse emissions are derived from the fuel supply, including uranium mining, milling, enrichment and fuel manufacture.' Dr Mudd found that financial and environmental costs escalate dramatically as the uranium ore is used. The deeper the mining process required to extract the ore, the higher the cost for mining companies, the greater the impact on the environment and the more resources needed to obtain the product. I t is clear that there is a strong sensitivity of energy and water consumption and greenhouse emissions to ore grade, and that ore grades are likely to continue to decline gradually in the medium to long term. These issues are critical to the current debate over nuclear power and greenhouse emissions, especially with respect to ascribing sustainability to such activities as uranium mining and milling. For example, mining at Roxby Downs is responsible for the emission of over one million tonnes of greenhouse gases per year and this could increase to four million tonnes if the mine is expanded.'

    Ningyo-toge Uranium Mine is subject to the environmental remediation. The main purposes are to take measures to ensure the radiation protection from the exposure pathways to humans in future, and to prevent the occurrence of mining pollution. The Mill Tailings Pond in the Ningyo-toge Uranium Mine has deposited mining waste and impounded water as a buffer reservoir before it is transferred to the Water Treatment Facility. It is located at the upstream of the water-source river, and therefore, for the environmental remediation, the highest priority has been put to it among many facilities in the Mine. So far, basic concept has been examined and planning has been carried out for the remediation. Also, a great number of data has been acquired, and using the data, some remediation activities have already begun, including designing for the upstream part of the Mill Tailings Pond. According to the current plan, the Mill Tailings Pond will be covered by capping following dewatering and compressing of mill tailings. The capping is composed of 'radon barrier' for lowering radon-gas dissipation and dose rate, and its protection layer. Natural materials are planned to be used for the capping to alleviate the future maintenance. After capping, data will be accumulated to verify the effectiveness of the capping, and if proved effective, it will be utilized for the capping of the downstream part. (author)

    Reed, A.K.; Meeks, H.C.; Pomeroy, S.E.; Hale, V.Q.

    1976-12-01

    This research program was initiated with the basic objective of making a preliminary assessment of the potential environmental impacts associated with the mining and milling of domestic uranium ores. All forms of pollution except radiation were considered. The program included a review of the characteristics and locations of domestic uranium ore reserves and a review of the conventional methods for mining and milling these ores. Potential environmental impacts associated with the entire cycle from exploration and mining to recovery and production of yellowcake are identified and discussed. Land reclamation aspects are also discussed. The methods currently used for production of yellowcake were divided into four categories - open pit mining-acid leach process, underground mining-acid leach process, underground mining-alkaline leach process, and in-situ mining. These are discussed from the standpoint of typical active mills which were visited during the program. Flowsheets showing specific environmental impacts for each category are provided

  5. Editorial: Mining in a Sustainable World

    2014-09-01

    Full Text Available Humanity has reaped great benefits from mining. Over the millennia that humans have practiced mining, there have been many obvious improvements in mining’s environmental and social impacts. However, some aspects of mining still involve an element of ecological violence and, in Australia, there is a growing amount of conflict concerned with mining. These two related issues – ‘ecological violence’ and ‘conflict’ – were explored at the ‘Mining in a Sustainable World’ conference on 13 to 15 October 2013 at the University of New England campus in Armidale, Australia. The conference was a joint initiative of the University of New England’s Peace Studies and Australian Centre for Agriculture and Law. Specifically, conference delegates were interested in exploring the work being done to reduce ecological violence and conflict. Articles in this special edition of the International Journal of Rural Law and Policy arose from that conference. This editorial provides an overview of the rationale for the conference and the issues explored.

  6. Final Environmental Impact Statement to construct and operate the Crownpoint Uranium Solution Mining Project, Crownpoint, New Mexico

    International Nuclear Information System (INIS)

    1997-02-01

    This Final Environmental Impact Statement (FEIS) addresses the proposed action of issuing a combined source and 11e(2) byproduct material license and minerals operating leases for Federal and Indian lands to Hydro Resources, Inc. (HRI). This action would authorize HRI to conduct in-situ leach uranium mining in McKinley County, New Mexico. Such mining would involve drilling wells to access the ore bodies, then recirculating groundwater with added oxygen to mobilize uranium found in the ore. Uranium would then be removed from the solution using ion exchange technology in processing plants located at three separate sites. As proposed by HRI, a central plant would provide drying and packaging equipment for the entire project. The Draft Environmental Impact Statement (DEIS) for the proposed action was prepared by an interagency review group comprising staff from the Nuclear Regulatory Commission, the Bureau of Indian Affairs, and the Bureau of Land Management, and published in October 1994. After evaluating the environmental impacts of the proposed action in the DEIS, the reviewing agencies concluded that the appropriate action was to issue the requested license and proposed leases authorizing HRI to proceed with the project. This FEIS reevaluates the proposed licensing action on the basis of written and oral comments received on the DEIS and on additional information obtained in 1995 and 1996. The FEIS describes and evaluates (1) the purpose of and need for the proposed action, (2) alternatives to the proposed action, (3) the environmental resources that could be affected by the proposed action and alternatives, (4) the potential environmental consequences of the proposed action and alternatives, and (5) the economic costs and benefits associated with the proposed action. Based on this assessment, the FEIS makes recommendations concerning the requested license and proposed leases

  7. Sustainability indicators and their application to the mining companies

    2000-01-01

    Today mining companies suffer strong pressure from organizations such as environmental groups, multilateral agencies, national governments, mining associations and the international media, to comply with good environmental practices and to face the new and important challenges imposed by the exploitation of deposits, of increasingly lower-grade ore, deepness and difficulty, and to integrate community issues in their decision making process. This article seeks to show the contribution that the development of environmental and social performance indicators and sustainability markers in the mining companies have in achieving sustainable development. This is especially useful in a developing country like Colombia, which has adopted a sustainable development economic model and where the mining sector has lead exportations and economy, but has also been responsible of big environmental damages and important social conflicts. Additionally, this work reports the existence of technologies and methodologies, e.g. those recommended by the Federal Environmental Agency of Germany, to design integrated sets of proven biophysical, economic and social indicators, including the conventional indicators of the mining process: input-outcome, capacity building, well being and participation, to be used in performance evaluation and optimization, cost-benefit analysis and strategic decision making, participative planning and progress monitoring, according to Alyson Warhurst (1997) in the mining and environmental research program of the Bath University

  8. Mainstreaming gender in the mines: results from an Indonesian colliery

    2006-04-15

    The extractive industrial sector, increasingly breaking new grounds in developing countries, is increasingly aware of the environmental and community issues involved in mining, including questions relating to gender. However, the main focus is on the impacts of mining on 'women' in the community, leaving aside practical issues related to the processes of mainstreaming gender within the company, in the workplace itself. What tools and approaches would be useful for those addressing gender issues in the mining sector, a sector that is still perceived as a masculine area of work? This short paper reports on a practical study undertaken in a privately run colliery in Indonesia. Through this example, it suggests ways in which to take a first step towards gender mainstreaming in the mining sector.

    New Caledonia is a widely recognised marine and terrestrial biodiversity hot spot. However, this unique environment is under increasing anthropogenic pressure. Major threats are related to land cover change and include fire, urban sprawling and mining. Resulting habitat loss and fragmentation end up in serious erosion of the local biodiversity. Mining is of particular concern due to its economic significance for the island. Open cast mines were exploited there since 1873, and scraping out soil to access ores wipes out flora. Resulting perturbations on water flows and dramatic soil erosion lead to metal-rich sediment transport downstream into rivers and the lagoon. Conflicting environmental and economic aspects of mining are discussed in this paper. However, mining practices are also improving, and where impacts are inescapable ecological restoration is now considered. Past and ongoing experiences in the restoration of New Caledonian terrestrial ecosystems are presented and discussed here. Economic use of the local floristic diversity could also promote conservation and restoration, while providing alternative incomes. In this regard, Ecocatalysis, an innovative approach to make use of metal hyperaccumulating plants, is of particular interest.

  10. Mitigation of social and environmental impacts resulting from final closure of uranium mines

    Cipriani, Moacir

    2002-11-01

    This thesis focus on the impact of uranium mines in Brazil. It is recent, in the order of the Brazilian mining, the concern with the impact of mining activities. The Federal Constitution of 1988 compels the miner to rehabilitate the degraded environment, in accordance with the technical solution demanded by the competent public agency, which makes use of a system of environmental norms conditioning the mining activity. However, the concern with the closure of mines is in an early stage, for whose achievement the public power still lacks of norms and regulations. The closure of the first uranium mining in Brazil assumes special meaning, because the possible environmental problems related to uranium mines are considered to be serious and the uranium industry is state owned. This thesis is divided in two sections. The first one describes the state of the art of the uranium industry and the rules and management practices regarding the final closure of uranium mining in Brazil and countries like Australia, Canada, USA and France, that have been selected on the basis of the following criteria: production, exportation, control of reserves and final consumption of uranium. In the second part, a case study of Pocos de Caldas mine is presented, with description of historical production, plant waste and the chemical treatment of the ore. This part also presents the research carried out since the beginning of the operations aiming to remedial actions, including the dismantling of surface structures, tailings reclamation, and ground-water restoration, following CNEN (Brazilian Nuclear Energy Commission) rules, as well as a survey of local press coverage of the impact of the industry. A final recommendation is made regarding a management model and strategies to mitigate social and environmental impacts resulting from final closure of the CIPC. (author)

    The development of the waste management and related environmental controls applied to uranium mining and processing in Australia is described. Major uranium deposits occur in the Alligator Rivers Region of the Northern Territory, a world heritage tropical wetland area with deep significance to Aboriginal people. The formulation of environmental controls took into consideration the unique features of the region in addition to experiences from earlier uranium mining operations. A description is given of the operations at Rum Jungle, the pollutants released and their effects on the environment. Commonwealth and State responsibilities for waste management and environmental control and the establishment of Codes of Practice are noted and proposed water management and tailings management programs at the four Alligator Rivers sites are described

    West Khasi Hills District of Meghalaya is identified as having a large and rich deposits of Uranium. However, actual extraction on a commercial scale that may lead to an increase in the socio-economic development of the state in particular and the country in general, is yet to be undertaken. This is due to lack of any baseline environmental survey giving rise to speculative information and causing a fear psychosis in the minds of the locals populace about the negative effects of Uranium mining. A preoperational survey and environmental monitoring of the proposed mining sites and its adjacent areas would establish the baseline status of the natural radioactivity and some chemical constituents in different environmental matrices via. air, water, soil, biota and aquatic ecosystems. The North Eastern Hill University, Shillong, Meghalaya has undertaken the Project funded by DST and BRNS, Department of Atomic Energy, Govt. of India which aims to provide baseline environmental data on ambient air, water and soil quality in and around the proposed Uranium mining site of Domiasiat, West Khasi Hills in the state of Meghalaya. Trace elements (elements like Mg, Zn, Ca, K, Na, Se, As, Fe, Cu, Co, Cr, Ni, Pb, Cd, Mn etc) and the status of the activity in the samples are determined. (author)

    Molecular Recognition Technology (MRT) plays an important role in the hydrometallurgical processing dissolved entities in solutions in the mining industry. The status of this industry with respect to sustainability and environmental issues is presented and discussed. The roles of MRT and ion exchange in metal separation and recovery processes in the mining industry are discussed and evaluated. Examples of MRT separation processes of interest to the mining community are given involving gold, cobalt purification by extraction of trace cadmium, rhenium, and platinum group metals (PGMs). MRT processes are shown to be sustainable, economically viable, energy efficient, and environmentally friendly, and to have a low carbon footprint.

    1996-01-01

    A summary of the environmental impact assessment for the Syncrude's proposed Aurora Mine was provided. Two mining areas will be opened. Aurora Mine North, located on oil sands leases 10, 12 and 34 will open first followed by the opening of Aurora Mine South, located on Lease 31. Each mining area will contain two extraction facilities, each capable of producing 6.25 million cubic metres of bitumen per year for a total annual capacity of 25 million cubic metres. The areas of land that will be disturbed by development of the Aurora Mines will total 15,171 hectares. The preferred pipeline, roadway and utility corridor and river crossing to be used for the Mine are shown. Production of SO 2 and NO x emissions from the Aurora Mine is expected to be very low, nevertheless, the cumulative effects of emissions from the mines will be addressed in the context of emissions from the existing or proposed oil sand facilities in the area. 7 tabs., 15 figs

    Environmental impact assessments and/or statements are an inherent part of any uranium mining project and are a prerequisite for the future opening of an exploitation and its final closure and decommissioning. Since they contain all information related to the physical, biological, chemical and economic condition of the areas where industrial projects are proposed or planned, they present invaluable guidance for the planning and implementation of environmental mitigation as well as environmental restoration after the mine is closed. They further yield relevant data on the socio-economic impacts of a project. The present report provides guidance on the environmental impact assessment of uranium mining and milling projects, including in situ leach projects which will be useful for companies in the process of planning uranium developments as well as for the regional or national authorities who will assess such developments. Additional information and advice is given through environmental case histories from five different countries. Those case histories are not meant to be prescriptions for conducting assessments nor even firm recommendations, but should serve as examples for the type and extent of work involved in assessments. A model assessment and licensing process is recommended based on the experience of the five countries. 1 fig., 5 tabs.

    International Nuclear Information System (INIS)

    2014-01-01

    The long term sustainability of nuclear power will depend on, among several factors, an adequate supply of uranium resources that can be delivered to the marketplace at competitive prices. New exploration technologies and a better understanding of the genesis of uranium ores will be required to discover often deep-seated and increasingly hard to find uranium deposits. Exploration, mining and milling technologies should be environmentally benign, and site decommissioning plans should meet the requirements of increasingly stringent environmental regulations and societal expectations. The purpose of this symposium is to analyse uranium supply–demand scenarios and to present and discuss new developments in uranium geology, exploration, mining and processing, as well as in environmental requirements for uranium operations and site decommissioning. The presentations and discussions at URAM-2014 will: - Lead to a better understanding of the adequacy of uranium sources (both primary and secondary) to meet future demand; - Provide information on geological models, new exploration concepts, knowledge and technologies that will potentially lead to the discovery and development of new uranium resources; - Describe new production technologies that have the potential to more efficiently and sustainably develop new uranium resources; and - Document the environmental compatibility of uranium production and the overall effectiveness of progressive final decommissioning and, where required, remediation of production facilities.

    Yager, Richard M.

    2013-01-01

    In 1994, the largest salt mine in North America, which had been in operation for more than 100 years, catastrophically flooded when the mine ceiling collapsed. In addition to causing the loss of the mine and the mineral resources it provided, this event formed sinkholes, caused widespread subsidence to land, caused structures to crack and subside, and changed stream flow and erosion patterns. Subsequent flooding of the mine drained overlying aquifers, changed the groundwater salinity distribution (rendering domestic wells unusable), and allowed locally present natural gas to enter dwellings through water wells. Investigations including exploratory drilling, hydrologic and water-quality monitoring, geologic and geophysical studies, and numerical simulation of groundwater flow, salinity, and subsidence have been effective tools in understanding the environmental consequences of the mine collapse and informing decisions about management of those consequences for the future. Salt mines are generally dry, but are susceptible to leaks and can become flooded if groundwater from overlying aquifers or surface water finds a way downward into the mined cavity through hundreds of feet of rock. With its potential to flood the entire mine cavity, groundwater is a constant source of concern for mine operators. The problem is compounded by the viscous nature of salt and the fact that salt mines commonly lie beneath water-bearing aquifers. Salt (for example halite or potash) deforms and “creeps” into the mined openings over time spans that range from years to centuries. This movement of salt can destabilize the overlying rock layers and lead to their eventual sagging and collapse, creating permeable pathways for leakage of water and depressions or openings at land surface, such as sinkholes. Salt is also highly soluble in water; therefore, whenever water begins to flow into a salt mine, the channels through which it flows increase in diameter as the surrounding salt dissolves

    Most modern mines in the developing world are located in rural areas, where agriculture is the main source of livelihood. This creates the potential of negative spillovers to farmers through competition for key inputs (such as land) and environmental pollution. To explore this issue, we examine the case of gold mining in Ghana. Through the estimation of an agricultural production function using household level data, we find that mining has reduced agricultural productivity by almost 40%. This...

    A professional, audit able environmental approach is the only path a responsible government, institution or company can take. Such an approach can be applied to a small petrol station, an oil refinery or a multi-million dollar mining development. Environmental issues cannot be divorced from socio-economic criteria; each impacts on the other. Twenty years ago, financial criteria ruled decision making and the environment tagged along a poor third to social and safety issues. Today, financial issued are still dominant, but decision makers realised that environmental issues hold the same weight as socio-economic criteria and the three are inexorably intertwined. (author)

    This study uses a vector autoregression (VAR) model to analyze changes in pollutants among different mining industries and related policy in China from 2001 to 2014. The results show that: (1) because the pertinence of standards for mining waste water and waste gas emissions are not strong and because the maximum permissible discharge pollutant concentrations in these standards are too high, ammonia nitrogen and industrial sulfur dioxide discharges increased in most mining industries; (2) chemical oxygen demand was taken as an indicator of sewage treatment in environmental protection plans; hence, the chemical oxygen demand discharge decreased in all mining industries; (3) tax reduction policies, which are only implemented in coal mining and washing and extraction of petroleum and natural gas, decreased the industrial solid waste discharge in these two mining industries.

    Gold mining has played an important role in Ghana’s economy, however the negative environmental and socio-economic effects on the host communities associated with gold mining have overshadowed these economic gains. It is within this context that this paper assessed in an integrated manner the environmental and socio-economic impacts of artisanal gold mining in the Tarkwa Nsuaem Municipality from a natural and social science perspective. The natural science group collected 200 random samples on bi-weekly basis between January to October 2013 from water bodies in the study area for analysis in line with methods outlined by the American Water Works Association, while the social science team interviewed 250 residents randomly selected for interviews on socio-economic issues associated with mining. Data from the socio-economic survey was analyzed using logistic regression with SPSS version 17. The results of the natural science investigation revealed that the levels of heavy metals in water samples from the study area in most cases exceeded GS 175-1/WHO permissible guideline values, which are in tandem with the results of inhabitants’ perceptions of water quality survey (as 83% of the respondents are of the view that water bodies in the study area are polluted). This calls for cost-benefits analysis of mining before new mining leases are granted by the relevant authorities. PMID:26821039

  6. Office of Geologic Respositories issues hierarchy for a Mined Geologic Disposal System (OGR/B-10)

    International Nuclear Information System (INIS)

    1986-09-01

    The Office of Geologic Repositories (OGR) has adopted an issues hierarchy for use by all Project Offices. The issues hierarchy provides a framework for representing issues related to regulatory requirements for siting and licensing a mined geologic disposal system (MGDS) and for describing the work that needs to be completed during site characterization to resolve those issues. The issues in the issues hierarchy are defined as the questions relating to the performance of the MGDS that must be resolved to demonstrate compliance with the applicable federal regulations (including 10 CFR Part 60, 10 CFR Part 960, 40 CFR Part 191, and 10 CFR Part 20). The issues hierarchy is structured around four broad areas of regulatory concern related to the requirements for siting and licensing an MGDS (postclosure performance, preclosure radiological safety, non-radiological environmental impacts, and feasibility and cost of MGDS development), and provides the framework for definition of the information needed to satisfy the applicable regulatory requirements in each of these areas. The purpose of this document is to present the issues hierarchy, describe the rationale used to develop the hierarchy, and describe how the issues hierarchy is used in program planning. Section 2 presents the overall rationale for the issues hierarchy, and explains the structure and organization of the hierarchy. Section 3 presents the issues hierarchy itself and Section 4 describes the basis for the development of individual issues. Section 5 provides a correlation between the issues and the applicable federal regulations being addressed. Section 6 describes how the issues drive development of plans in support of siting and licensing requirements through use of an issue resolution strategy that includes performance allocation

    1990-01-01

    Milt Ward has asked me to say a few words on two issues which have been high on the AMC regulatory agenda for many years--access to the public lands and the environment. Both lie at the interface between mining, an essential industrial activity, and the protection and conservation of other resource values. The operation of the mining law of 1872 has been under public scrutiny for many years. Many in the mining industry have cooperated in the development of workable regulations, realizing that regulation could have the effect of ameliorating the pressure for additional withdrawals or legislation limiting access to the public lands for exploration. Thus by the 1980s, the activities of some explorers and miners which in an earlier day gave rise to justified concern, all but disappeared from Public Lands. There can be no doubt that environmental issues are the most pressing issues confronting the domestic mining and minerals processing industries. Leaders in government willing to take a position on the appropriate balance between measurable costs and presumed benefits of environmental regulations are rare. Thus those of us involved in the creation of wealth for the use and benefit of our fellow men must commit ourselves to the unending task of communicating the benefits of our activities to the public which enjoy those benefits. The mining industry is an industry essential to our way of life. That fact should give us the continuing confidence to demonstrate and to communicate that we are responsible guardians of the world's resources

    The successful implementation of the environmental practices in the mining industry is of a paramount importance, as it not only prevents both local and trans-border pollution but also guarantees clean and healthy environment for the people regardless of their place of habitation. It is especially important to encourage the progress of the environmental practices implementation in developing countries because such countries have resource-oriented economy based on exploitation of nonrenewable resources. Poor environmental practices in developing countries will lead to local environmental crises that could eventually spill into surrounding countries including the most economically advanced. This abstract is a summary of a two-year research project attempted (1) to determine deficiencies of the mining sector ecological practices in developing countries and (2) to suggest substitute practices from developed countries that could be adapted to the developing countries reality. The following research methods were used: 1. The method of the system analysis, where the system is an interaction of the sets of environmental practices with the global mining sector; 2. The comparative method of inquiry, where the comparison was made between environmental protection practices as implemented in the US (developed country) and the developing countries such as RF, Mongolia mining sectors; 3. Quantitative date analysis, where date was collected from "The collection of statistic data", Russian Geographic Society Annual reports, the US EPA open reports, and the USGS Reports; The following results were obtained: Identified the systemic crisis of the ecological environmental policies and practices in the mining sector in developing countries based on the exploitation of nonrenewable resources, absence of the ecological interest by the mining companies that lack mechanisms of environmental and public health protection, the lack of insurance policy, the lack of risk assistance, and in the

    Primary copper production is a major activity in the mining sector of several countries. However, it is highly energy-intensive and poses important environmental hazards. In the case of Chile, the world's largest copper producer (40% of world total), we examine its energy consumption and energy-related environmental implications over a time horizon of 25 years. Concerning the latter, we focus on greenhouse-gas (GHG) emissions, one of the most debated environmental issues. This paper follows up our previous report in which the current situation was analyzed and a particular technical option for improving the energy efficiency and concurrently reducing GHG emissions was discussed. Estimated reference or base (BS) and mitigation (MS) scenarios are developed for the period ending in 2020. The former assesses the energy demand projected in accordance with production forecasts and specific energy consumption patterns (assuming that energy efficiency measures are adopted 'spontaneously') with their resultant GHG emissions, while the latter assumes induced actions intended to reduce emissions by adopting an aggressive policy of efficient energy use. For the year 2020, the main results are: (i) BS, 1214 t of CO 2 /ton of refined copper content (49% lower than in 1994); (ii) MS, 1037 t of CO 2 /t of refined copper content (56% lower than in 1994). CO 2 emissions have been estimated considering both fuel and electricity process requirements. (author)

    spatio-temporal data integration to following phases: • pre-integration data processing - different data set can be physically stored in different formats (e.g. relational databases, text files); it might be necessary to pre-process the data sets to be integrated, • identification of transformation operations necessary to integrate data in spatio-temporal dimensions, • identification of transformation operations to be performed on non-spatio-temporal attributes and • output data schema and set generation - given prepared data and the set of transformation, operations, the final integrated schema is produces. Spatio-temporal dimension brings its specifics also to the problem of mining spatio-temporal data sets. Spatio-temporal relationships exist among records in (s-t) data sets and those relationships should be considered in mining operation. This means that when analyzing a record in spatio-temporal data set, the records in its spatial and/or temporal proximity should be taken into account. In addition, the relationships discovered in spatio-temporal data can be different when mining the same data on different scales (e.g. mining the same data sets on 50 km grid with daily data vs. 10 km grid with hourly data). To be able to do effective data mining, we first needed to gather a sufficient amount of environmental data covering similar area and time span. For this purpose we have engaged in cooperation with several organizations working in the environmental domain in Slovakia, some of which are also our partners from previous research efforts. The organizations which volunteered some of their data are the Slovak Hydro-meteorological Institute (SHMU), the Slovak Water Enterprise (SVP), the Soil Science and Conservation Institute (VUPOP), and the Institute of Hydrology of the Slovak Academy of Sciences (UHSAV). We have prepared scenarios from general meteorology, as well as specialized in hydrology and soil protection.

    Allogenic hematopoietic stem cell transplantation is a curative treatment for patients with advanced hematologic malignancies. However, the long-term mental health issues of siblings who were not selected as donors (non-donor siblings, NDS) in the transplantation have not been well assessed. Data mining is useful in discovering new findings from a large, multidisciplinary data set and the Scenario Map analysis is a novel approach which allows extracting keywords linking different conditions/events from text data of interviews even when the keywords appeared infrequently. The aim of this study is to assess mental health issues on NDSs and to find helpful keywords for the clinical follow-up using a Scenario Map analysis. A 47-year-old woman whose younger sister had undergone allogenic hematopoietic stem cell transplantation 20 years earlier was interviewed as a NDS. The text data from the interview transcriptions was analyzed using Scenario Mapping. Four clusters of words and six keywords were identified. Upon review of the word clusters and keywords, both the subject and researchers noticed that the subject has had mental health issues since the disease onset to date with being a NDS. The issues have been alleviated by her family. This single subject study suggested the advantages of data mining in clinical follow-up for mental health issues of patients and/or their families.

    Full Text Available Extractive industries are often claimed to contribute to both poverty reduction and economic growth. Yet, there is also a body of research that suggests natural resource dependence can result in limited development, environmental degradation and social upheaval. This paper examines differences in the socioeconomic and environmental state of mining and non-mining communities in rural Vietnam in order to understand the extent to which mining contributes to livelihood development and socioeconomic well-being. In particular, we examine the role that “corporate social responsibility” (CSR plays in supporting community development in Phuoc Son and Phu Ninh districts, Quang Nam province. Content analysis of newspapers, government documents and mining company reports provided a contextual overview of mining operations and community relations in each study area. Semi-structured interviews were used to collect information from local and regional stakeholders to further understand perceived impacts of mining operations on local communities. Our study finds that in comparison to non-mining communities, communities with active mines demonstrated increased job development, decreased poverty rates, enhanced infrastructure and social development along with increased incidences of CSR initiatives. However, a number of adverse effects from mining activities were reported including environmental degradation (e.g., deforestation, water pollution, etc. increased criminal activity and drug addiction. Dependence on mine-related employment in local communities becomes acutely apparent when temporary mine closures result in widespread unemployment. Local governments may be the greatest beneficiaries of mining with increased tax revenues and enhanced management potential of leased land. Non-mining communities without direct benefits from mining activities maintained economic diversity and were therefore more resilient to economic shocks such as nearby mine closures.

  16. Identification of Social and Environmental Conflicts Resulting from Open-Cast Mining

    Open-cast mining is related to interference in the natural environment. It also affects human health and quality of life. This influence is, among others, dependent on the type of extracted materials, size of deposit, methods of mining and mineral processing, as well as, equally important, sensitivity of the environment within which mining is planned. The negative effects of mining include deformations of land surface or contamination of soils, air and water. What is more, in many cases, mining for minerals leads to clearing of housing and transport infrastructures located within the mining area, a decrease in values of the properties in the immediate vicinity of a deposit, and an increase in stress levels in local residents exposed to noise. The awareness of negative consequences of taking up open-cast mining activity leads to conflicts between a mining entrepreneur and self-government authorities, society or nongovernment organisations. The article attempts to identify potential social and environmental conflicts that may occur in relation to a planned mining activity. The results of the analyses were interpreted with respect to the deposits which were or have been mined. That enabled one to determine which facilities exclude mineral mining and which allow it. The research took the non-energy mineral resources into consideration which are included in the group of solid minerals located in one of the districts of Lower Silesian Province (SW Poland). The spatial analyses used the tools available in the geographical information systems

    2016-01-01

    Increasing global demand for metals is straining the ability of the mining industry to physically keep up with demand (physical scarcity). On the other hand, social issues including the environmental and human health consequences of mining as well as the disparity in income distribution from mining revenues are disproportionately felt at the local community level. This has created social rifts, particularly in the developing world, between affected communities and both industry and governments. Such rifts can result in a disruption of the steady supply of metals (situational scarcity). Here we discuss the importance of mining in relationship to poverty, identify steps that have been taken to create a framework for socially responsible mining, and then discuss the need for academia to work in partnership with communities, government, and industry to develop trans-disciplinary research-based step change solutions to the intertwined problems of physical and situational scarcity.

    Kharchenko, V.; Oumnov, V.

    1996-01-01

    The state of the Russian coal industry is complicated both economically and environmentally. Most mines are unprofitable. Several coal mines are intended to be closed. So, under existing conditions, coal mines are unable to give much attention to environmental protection problems. At the same time, coal mining is one of the most polluting industries. The main trends in this industry's negative influence upon the environment are: land spoilage and immobilization to lay out open-pit mines and mineral waste dump areas and tailing piles as well as with industrial waste water runoff; atmospheric pollution with the air coming from underground and substances blown off from dumps, hydrogeological regime intervention in coal mining areas, etc. One way to solve environmental problems in coal mining is a more rational utilization of the accompanying natural coal resources. Such measures make it possible to obtain complementary profits not only at the expense of reducing environmental destruction but producing new kinds of goods or services as well. Examples of similar solutions are solid mineral wastes utilization, underground space utilization, coal gas utilization and other issues

    1993-01-01

    While environmental issues are constantly changing and becoming increasingly regulated, the key to high performance in environmental management is the application of best practice - best practicable technology of sites - specific standards, practices and procedures. The author also emphasised that the application of best practice in environmental management of mine sites is a dynamic process and that requires a combination of efficient environmental management and efficient production. Timing of application of technology and social factors are also determining factors in this process. The particular case of the Ranger uranium mine site is presented were the major environmental issues relate to water management, tailing management and rehabilitation. The management procedure used at Ranger for a research project proposal is outlined

    Minerals in the environment and products manufactured from mineral materials are all around us and we use and come into contact with them every day. They impact our way of life and the health of all that lives. Minerals are critical to the Nation's economy and knowing where future mineral resources will come from is important for sustaining the Nation's economy and national security. The U.S. Geological Survey (USGS) Mineral Resources Program (MRP) provides scientific information for objective resource assessments and unbiased research results on mineral resource potential, production and consumption statistics, as well as environmental consequences of mining. The MRP conducts this research to provide information needed for land planners and decisionmakers about where mineral commodities are known and suspected in the earth's crust and about the environmental consequences of extracting those commodities. As part of the MRP scientists of the Western Mineral and Environmental Resources Science Center (WMERSC or 'Center' herein) coordinate the development of national, geologic, geochemical, geophysical, and mineral-resource databases and the migration of existing databases to standard models and formats that are available to both internal and external users. The unique expertise developed by Center scientists over many decades in response to mineral-resource-related issues is now in great demand to support applications such as public health research and remediation of environmental hazards that result from mining and mining-related activities. Western Mineral and Environmental Resources Science Center Results of WMERSC research provide timely and unbiased analyses of minerals and inorganic materials to (1) improve stewardship of public lands and resources; (2) support national and international economic and security policies; (3) sustain prosperity and improve our quality of life; and (4) protect and improve public health, safety, and environmental quality.

    The Nuclear Regulatory Commission (NRC) has indicated that the identification of the issues that must be resolved to complete licensing assessments of site and design suitability is an important step in the licensing process. The issues hierarchy developed by the Office of Geologic Repositories (OGR) for the mined geologic disposal system (MGDS) are based on the issues-hierarchy concept presented in the Mission Plan. Specific questions are encompassed by the general issue statements in the OGR issues hierarchy. The OGR issues hierarchy is limited to the issues related to the siting and licensing requirements of applicable federal regulations and does not address the requirements of other regulations, functional or operating requirements for the MGDS, or requirements for the integration and the design/operational efficiency of the MGDS. 4 figs

    1994-01-01

    An Environmental Impact Assessment (EIA) is a public document which evaluates the impact of a new company or a new project on the environment and it also lays out the possible alternatives. The present EIA was worked out to get an insight into the polluting effects of the Ajka Mining and Power Company in Ajka, Hungary and to understand what hinders the abatement of the pollution. The Ajka coal has a high sulphur content and is slightly radioactive. The Power Plant is situated in the neighborhood of the town Ajka and the wind usually blows the releases in the direction of the town. The radioactive sludge is also stored at the border of the town and its radioactivity exceeds the limit set for the Paks Power Plant (in Hungary). Alternatives for the present technology are explored. Nil-condensation and/or energy conservation seem to be the best alternatives. Theoretically, the Regional Environmental Inspectorate is responsible for all survey of pollution, which they monitor with their own equipment, with data obtained from the company or from other monitoring companies. However, the pollution of the Ajka Mining and Power Company is not completely monitored. (authors)

  6. Challenges in waste management and environmental restoration in the uranium mining industry

    International Nuclear Information System (INIS)

    Jarrell, J.

    2011-01-01

    Two components dominate the waste management efforts at conventional Canadian uranium mining and milling operations. These are the waste rock generated in the mining of ore as well as the mill tailings -- which are the residue solids remaining after uranium extraction. Much has changed in the management of these wastes over the years. Visually, current sites are generally more compact than those developed earlier, due to higher grade ores and less land disturbance. However, the more significant strides being made to better manage uranium mining wastes deal more with improved chemical and physical controls rather than those changes which are visible. Segregation of waste rock to separate out potentially problematic material within the more weakly mineralized halo surrounding the ore is now a core strategy. This segregation is based on both the waste rock's chemical and radiological characteristics. Better controls have also been introduced on tailings physical properties to minimize their permeability, along with better chemical controls to minimize tailings contaminant solubility. Efforts to engineer tailings properties are coupled with contrasting hydraulic conductivity between the consolidated tailings mass and surrounding geologic materials. This creates the necessary long-term containment controls built into modern tailings management facilities. Current challenges include selecting the correct decommissioning assumptions such as future land use and required environmental acceptance criteria, along with decisions as to when to carry out reclamation work in the life cycle of the mine and mill. Public discussion of restoration plans throughout the life of the facility is essential to build acceptable solutions. Along with challenges come successes. Most recently, improvements have been made in reducing treated water molybdenum and selenium levels. Other successes include the application of reverse osmosis technology on a large scale, recycling of uranium

    Full Text Available Selenium pollution has been a topic of extensive research dating back further than the last decade and has attracted significant attention from several environmental and regulatory agencies in order to monitor and control its discharge from myriad industrial sources. The mining industry is a prime contributor of hazardous selenium release in the aquatic systems and is responsible for both acute and chronic impacts on living organisms. Herein we provide an overview of selenium contamination issues, with a specific focus on selenium release from mining industries, including a discussion of various technologies commonly employed to treat selenium-impacted waters from mining discharge. Different cases pertaining to selenium release from Alaskan mines (during years 2000–2015 are also presented, along with measures taken to mitigate high concentration releases. For continued resource exploration and economic development activities, as well as environmental preservation, it is important to fundamentally understand such emerging and pressing issues as selenium contamination and investigate efficient technological approaches to counter these challenges.

    Full Text Available Mining activities and the waste products produced can have significant impact on the surrounding environment - ranging from localized surface and ground water contamination to the damaging effects of airborne pollutants on the regional ecosystem. The long term monitoring of environmental impacts requires a cost effective method to characterize land cover and land cover changes over time. As per the guidelines of Ministry of Environment and Forest, Govt. of India, it is mandatory to study and analyze the impacts of mining on its surroundings. The use of remote sensing technology to generate reliable land cover maps is a valuable asset to completing environmental assessments over mining affected areas. In this paper, a case study has been discussed to study the land use – land cover status around 10 Km radius of open cast limestone mine area and the subsequent impacts on environmental as well as social surroundings.

    2002-01-01

    Rehabilitation of land after mining is an issue that society has been wrestling with for at least 400 years. The issue is made even more emotive when the mineral extracted has been uranium. Over the past 50 years or so society has become ever more aware of the environment and the level of concern for proper environmental management has also increased. Today the community expects that mining in general, and uranium mining in particular, will be undertaken in an environmentally sensitive manner. As a consequence the expectations and standards for rehabilitation demanded by the community and regulators have been increasing and improving over time. Today the rehabilitation process is driven by issues of sustainable development, stakeholder involvement and consultation, inter-and intragenerational equity and a strong desire for environmental protection to be of the highest order. The paper describes this progressive improvement in rehabilitation standards using the uranium mines of northern Australia as case histories. (author)

    A post-rehabilitation audit of the derelict Conrad base metal mine, eastern Australia, indicates ongoing environmental hazard regarding acid mine drainage and concentrations of arsenic and lead to 3 wt% in the soil and sediment. In order to rehabilitate remote contaminated sites effectively, on-site analyses should be carried out to ensure that the materials used to rehabilitate the site are not contaminant-bearing. Understanding the geomorphic setting of the rehabilitated areas is also important in understanding where, and for what period, contaminated materials might be stored in fluvial systems downstream of mine workings. Chemical and geomorphic audits should form a fundamental part of all rehabilitation works to ensure favourable environmental outcomes. - Post-rehabilitation audit of mine reveals ongoing As and Pb environmental hazard enhanced by acid drainage and site geomorphology

    The exhibition „Uranium Mining in and for Europe“ took place in the European Parliament in Brussels on September 25/26 2012. This brochure sheds light on this highly topical issue with additional information to the exhibition but also as a stand-alone pu¬blication. It shows why uranium mining is again on the agenda in Europe and the risks resulting from a possible revival of this technology. After a short introduction on general aspects of nuclear energy our brochure focuses on uranium mining: necessary process steps, energy needs and CO2 emissions and the environmental impacts. Several examples illustrate the current develop-ment in several countries of the European Union. Our brochure is for all those who want to gain deeper understanding of nuclear energy. The panels of this exhibition are available for lending on request; the digital version can be found on the home page of the Austrian Institute of Ecology. Special thanks go to Peter Diehl and a multitude of European NGOs, which provided their knowledge on current issues on uranium mining and that way made an important contribution to this brochure. The exhibition and this brochure were commissioned by the Vienna Ombuds Office for Environmental Protection (Wiener Umweltanwaltschaft). Both are based on an earlier version of the exhibition which was titled “Return of Uranium Mining to Europe?” from 2008, developed in the framework of the Joint Project with the support of the Austrian Lebensministerium. We appreciate your interest in this important topic and hope you will find this brochure to be stimulating and informative reading. (author)

    This overview will discuss a number of the issues posed by the challenge of international environmental health. The reasons that environmental problems occurring elsewhere in the world are of importance to occupational and environmental physicians in North America include the interconnectedness of the biosphere of our planet so that environmental alterations in one part of the globe can have an adverse outcome on our health and well-being; the often high levels of pollution and environmental degradation elsewhere provide an opportunity to determine and predict adverse consequences of environmental agents pertinent to protecting our own health; and, most importantly, our own ability to provide assistance in helping economic development occur in a setting of low risk of environmental pollution.

  19. Yucca Mountain and the environmental issue

    The scientists and engineers who work on the Yucca Mountain Project keenly feel their responsibility - to solve an important national environmental issue. Addressing the issue of nuclear waste disposal may also help keep the nuclear option viable. Under congressional mandate, they are working to find that solution despite tough opposition from the state of Nevada. Nevada and the US Department of Energy (DOE) have been litigating the issue of environmental permits for almost 2 years now, and the court decisions have all favored DOE. The DOE's site characterization efforts are designed to determine whether Yucca Mountain can safely store spent nuclear fuel for the next 10,000 yr. DOE is studying the rocks, the climate, and the water table to make sure that the site is suitable before anything is built there. The success of the Yucca Mountain Project is vital to settling existing environmental issues as well as maintaining the viability of nuclear energy. Through efforts in Congress and outreach programs in Nevada, DOE hopes to inform the public of the mission and begin the process of site characterization

  1. EDITORIAL: Environmental justice: a critical issue for all environmental scientists everywhere

    2007-10-01

    It is now commonly understood that much of the worldwide burden of environmental ill health falls disproportionately on poorer peoples [1,2]. There is also substantial evidence that much environmental damage internationally is the result of the actions of richer nations or richer groups within nations—with impacts on poorer nations and poorer groups within nations [1,3,4]. It is becoming clear also that poorer peoples internationally experience multiple environmental harms, and that these may have a cumulative effect. The world is becoming more urbanized, and cities are becoming the locus for many of the local issues of environmental damage and environmental harm [4,5]. But cities are also responsible for substantial international environmental damage: for example, it is increasingly evident that cities are one of the main generators of climate change, and that the actions of people in cities in the rich world are deeply linked to the well-being of the overall ecosystem and of people worldwide. Environmental justice is a concept that links the environmental health science documenting these harms, to debates around rights, justice and equity. It fundamentally deals with the distribution of environmental goods and harms—and looks at who bears those harms and who is responsible for creating those harms, in both a practical sense but also in terms of policy decisions. It is a radical environmental health movement that has evolved from civil society groups, angered at what they perceive as the `unjust' distribution of environmental resources for health and, conversely the `unjust' distribution of environmental harms. The movement now includes a collaboration of non-governmental organizations with environmental scientists, public health professionals, and lawyers, all working on the issue of the distributions of environmental harms and the rights of everyone to a healthy environment. This special issue is both timely and important. Environmental justice is moving

    The objective of the IAEA’s programme on nuclear power and related nuclear fuel cycle activities is to promote the development of nuclear power and fuel cycle technologies that are economically viable, safe, environmentally friendly, proliferation–resistant and sustainable. Natural uranium is one of the basic raw materials for nuclear fuel. And so with this in mind we have come together here to participate in the 2009 International Symposium on Uranium Raw Material for the Nuclear Fuel Cycle, URAM- 2009. This is the latest in a series of symposia devoted to issues relating to the Uranium Production Cycle (UPC) and many of you will have been at the two previous meetings in 2000 and 2005. Looking back on those meetings we should remember how the intensity and scale of activity in the uranium production cycle has changed since 2000. At that symposium we were looking at how to keep the industry going whilst cleaning up the legacies of the past, ensuring minimal environmental problems for operating mines then and into the future and working out how the long term future of the industry would look. In addition we also considered the issues of maintaining our skills base and ensuring that exploration would continue so we might be prepared for the future.

  7. Highland Uranium Solution Mining Project. Draft environmental statement

    International Nuclear Information System (INIS)

    1978-05-01

    Exxon Minerals Co. proposes to conduct production-scale solution mining (in situ leaching) of uranium within the existing Highland Operation area in Converse County, Wyoming. The project would result in the temporary removal of 200 acres from grazing and the actual disturbance of 50 acres. About 4500 acre-ft of water will be withdrawn from the ore zone aquifer over the 10-year life of the project. There will be no discharge of liquid effluents from the project; atmospheric effluents will be within acceptable limits. Radiation doses at the nearest ranch resulting from solution mining activities were estimated. The project proposes the production and utilization of 1 to 3 million lb of uranium resources. It will not produce any significant socioeconomic impact on the local area. Alternatives to the project were considered, and conditions for issuing the source material license are listed

  8. Sediment processes modelling below hydraulic mining: towards environmental impact mitigation

    Science.gov (United States)

    Chalov, Sergey R.

    2010-05-01

    Placer mining sites are located in the river valleys so the rivers are influenced by mining operations. Frequently the existing mining sites are characterized by low contribution to the environmental technologies. Therefore hydraulic mining alters stream hydrology and sediment processes and increases water turbidity. The most serious environmental sequences of the sediment yield increase occur in the rivers populated by salmon fish community because salmon species prefer clean water with low turbidity. For instance, the placer mining in Kamchatka peninsula (Far East of Russia) which is regarded to be the last global gene pool of wild salmon Oncorhynchus threatens the rivers ecosystems. System of man-made impact mitigation could be done through the exact recognition of the human role in hydrological processes and sediment transport especially. Sediment budget of rivers below mining sites is transformed according to the appearance of the man-made non-point and point sediment sources. Non-point source pollution occurs due to soil erosion on the exposed hillsides and erosion in the channel diversions. Slope wash on the hillsides is absent during summer days without rainfalls and is many times increased during rainfalls and snow melting. The nearness of the sources of material and the rivers leads to the small time of suspended load increase after rainfalls. The average time of material intake from exposed hillsides to the rivers is less than 1 hour. The main reason of the incision in the channel diversion is river-channel straightening. The increase of channel slopes and transport capacity leads to the intensive incision of flow. Point source pollution is performed by effluents both from mining site (mainly brief effluents) and from settling ponds (permanent effluents), groundwater seepage from tailing pits or from quarries. High rate of groundwater runoff is the main reason of the technological ponds overfilling. Intensive filtration from channel to ponds because of

    The large-scale and super-strength development of mineral resources in mining cities in long term has made great contributions to China's economic construction and development, but it has caused serious damage to the ecological environment even ecological imbalance at the same time because the neglect of the environmental impact even to the expense of the environment to some extent. In this study, according to the characteristics of mining cities, the scientific and practical eco-environmental vulnerability evaluation index system of mining cities had been established. Taking Panzhihua city of Sichuan province as an example, using remote sensing and GIS technology, applying various types of remote sensing image (TM, SPOT5, IKONOS) and Statistical data, the ecological environment evaluation data of mining cities was extracted effectively. For the non-linear relationship between the evaluation indexes and the degree of eco-environmental vulnerability in mining cities, this study innovative took the evaluation of eco-environmental vulnerability of the study area by using artificial neural network whose training used SCE-UA algorithm that well overcome the slow learning and difficult convergence of traditional neural network algorithm. The results of ecoenvironmental vulnerability evaluation of the study area were objective, reasonable and the credibility was high. The results showed that the area distribution of five eco-environmental vulnerability grade types was basically normal, and the overall ecological environment situation of Panzhihua city was in the middle level, the degree of eco-environmental vulnerability in the south was higher than the north, and mining activities were dominant factors to cause ecoenvironmental damage and eco-environmental Vulnerability. In this study, a comprehensive theory and technology system of regional eco-environmental vulnerability evaluation which included the establishment of eco-environmental vulnerability evaluation index

    Full Text Available Coal mining activities may cause a series of environmental and socio-economic issues in communities around the mining area. Mining can become an obstacle to environmental sustainability and a major hidden danger to the security of the local ecology. Therefore, the coal mining industry should follow some specific principles and factors in achieving sustainable development. These factors include geological conditions, land use, mining technology, environmental sustainability policies and government regulations, socio-economic factors, as well as sustainability optimization for post-mining land use. Resources of the remains of the coal which is defined as the last remaining condition of the resources and reserves of coal when the coal companies have already completed the life of the mine or the expiration of the licensing contract (in accordance with government permission. This research uses approch of knowledge-driven GIS based methods mainly Analytical Hierarchy Process (AHP and Fuzzy logic for utilizing coal remaining resources and post-mining land use planning. The mining area selected for this study belongs to a PKP2B (Work Agreement for Coal Mining company named Adaro Indonesia (PT Adaro. The result shows that geologically the existing formation is dominated by Coal Bearing Formation (Warukin Formation which allows the presence of remains coal resource potential after the lifetime of mine, and the suitability of rubber plantation for the optimization of land use in all mining sites and also in some disposal places in conservation areas and protected forests.

    elevation of blood mercury levels exceeding the then recommended exposure level of 20ppb in 12 out of the 43 (27.9%) residents examined. The majority of the volunteers were former mine workers. In this study the abnormal findings included gingivitis, mercury lines, gum bleeding and pterydium. The most common neurologic complaints were numbness, weakness, tremors and incoordination. Anemia and elevated liver function tests were also seen in a majority of those examined. The assessment also revealed a probable association between blood mercury level and eosinophilia. The same association was also seen between high mercury levels and the presence of tremors and working in the mercury mine. To date, there are very limited environmental and health studies on the impact of both total and methylmercury that have been undertaken in the Philippines. Thus, this area of study was selected primarily because of its importance as an emerging issue in the country, especially regarding the combined effects of total and methylmercury low-dose and continuous uptake from environmental sources. At present the effects of total mercury exposure combined with MeHg consumption remain an important issue, especially those of low-dose and continuous uptake. Results of the study showed that four (4) species of fish, namely ibis, tabas, lapu-lapu and torsillo, had exceeded the recommended total mercury and methylmercury levels in fish (NV>0.5 microg/gf.w., NV>0.3 microg/gf.w., respectively). Saging and kanuping also exceeded the permissible levels for methylmercury. Total and methylmercury in canned fish, and total mercury in rice, ambient air and drinking water were within the recommended levels, however, additional mercury load from these sources may contribute to the over-all body burden of mercury among residents in the area. Surface water quality at the mining area, Honda Bay and during some monitoring periods at Palawan Bay exceeded total mercury standards (NV>0.002 ng/mL). Soil samples in two

  15. Preliminary environmental assessments of disposal of rock mined during excavation of a federal repository for radioactive waste

    International Nuclear Information System (INIS)

    1977-09-01

    Since the environmental impact of mined rock handling will be dependent not only upon the nature of the material and the way in which it might be disposed but also upon the features of the disposal site area and surroundings, it was necessary to select ''reference environmental locii'' within the regions of geological interest to typify the environmental setting into which the rock would be placed. Reference locii (locations) were developed for consideration of the environmental implications of mined rock from: bedded rock salt from the Salina region, bedded rock salt from the Permian region, dome rock salt from the Gulf Interior region, Pierre shale from the Argillaceous region, granite from the crystalline rock region, volcanic basalt rock from the crystalline ash region, and carbonate rock from the limestone region. Each of these reference locii was examined with respect to those demographic, geographic, physical and ecological attributes which might be impacted by various mined rock disposal alternatives. Alternatives considered included: onsite surface storage, industrial or commercial use, offsite disposal, and environmental blending. Potential impact assessment consists of a qualitative look at the environmental implications of various alternatives for handling the mined rock, given baseline characteristics of an area typified by those represented by the ''reference locus''

    McKlveen, J.W.; Kvasnicka, J.

    1989-01-01

    There are two uranium mines in the Northern Territory of Australia, Ranger and Nabarlek. The Ranger mine, the only producing operation, is located in the Kakadu National Park, which has been listed on the United Nations' World Heritage list. The park is dedicated to preserving the Australian aboriginal culture: It contains several aboriginal villages and historic sites. Uranium mining in the park has been accepted quite well by the public and the aborigines. Employees of the Ranger mine and their relatives have established a public information program that includes tours of the mining and milling operations. There is no environmental impact to the area from the mining and milling of uranium at the Ranger site. The region around the Grand Canyon contains many highgrade uranium deposits. The ore is contained in unique breccia pipe formations. The pipes, which resemble a cylinder with a diemter of ∼ 100 m and a height of ∼ 300 m, originated as limestone solution cavities located ∼ 400 m below the plateau. There are several exposed deposits along the canyon walls, but no mining operations are allowed within the park boundaries. While the real environmental impact is insignificant, the perceived impact is tremendous. Many special-interest groups have attempted to halt the mining operations. No valid environmental impacts have been predicted or observed as a result of the current mining operations. However, one mine has been delayed for religious reasons by a local tribe or native Americans

    1978-04-01

    This article continues a Forum series on recent trends in mining contracts between host countries and foreign investors begun in the April 1977 issue. Based on intensive research carried out for the preparation of a book on Mining Ventures in Developing Countries, published recently in the Federal Republic of Germany, the authors discuss sources of finance, institutions, exchange controls and special accounts, royalties, income taxation, and equity participation. They conclude that taxation is most likely to remain the principal source of income; equity participation should be evaluated carefully as it does not automatically guarantee maximum benefits. The combination of taxes and royalties provide a steady flow of income. An increase of the total tax burden beyond a certain percentage may be counterproductive for the host country, as it encourages the investor to look for less controllable means of shifting profits or discourages investment for exploration and development. 21 notes and refs.

    Full Text Available The coal mining has brought a series of ecological problems and environmental problems in permafrost regions. Taking Muli coal-mining area as an example, this article attempts to analyse the environmental harms caused by coal mining and its protection measures in permafrost regions of Qinghai–Tibet Plateau. This article analyses the influence of open mining on the surrounding permafrost around the open pit by using the numerical simulation. The results show that (1 based on the interrelation between coal mining and permafrost environment, these main environmental harm include the permafrost change and the natural environment change in cold regions; (2 once the surface temperature rises due to open mining, the permafrost will disappear with the increase of exploitation life. If considering the solar radiation, the climate conditions and the geological condition around the pit edge, the maximum thaw depth will be more than 2 m; (3 the protection measures are proposed to avoid the disadvantage impact on the permafrost environment caused by coal mining. It will provide a scientific basis for the resource development and environment protection in cold regions.

    International Nuclear Information System (INIS)

    1985-11-01

    In 1968, Gulf Minerals Ltd. discovered uranium mineralization around a small body of water referred to as Rabbit Lake. Subsequent drilling at the site discovered sufficient uranium to justify development, and by 1974 the mining and milling processes were in operation and routine monitoring of the release of effluents to Wollaston Lake began, and has been carried out since. Collins, Pow and Hidden Bays of Wollaston Lake are adjacent to the uranium mining operations and the latter two have received drainage and treated process waters. In addition to the Umpherville River, 13 smaller streams of various sizes enter Hidden Bay. Of these, the small stream draining Park's Lake is affected, to a small degree, by the mining operation, while the second stream draining the tailings management area is affected to a significant degree by the facility. With the exception of those discharges to the Pow Bay watershed, virtually all of the mine water, process water and site runoff that may be potentially contaminated by the mining and milling operation is discharged after treatment and routine monitoring to Hidden Bay, the location of Hidden Bay Lodge which is the closest permanent population to the mine site. For these reasons, data from Hidden Bay were reviewed in detail. Both monitoring data and present and future site plans would suggest that if any environmental concerns were to raise related to water discharges, Hidden Bay would be the first place where they would become apparent

    2016-12-01

    Full Text Available This study aims to find higher education students’ perceptions about environmental issues and how the perceptions are related to perceptions of media coverage. This study investigates higher education students’ perceptions of the seriousness of environmental issues and their relation to perceptions of media coverage. Higher education students perceived a global problem, lack of clean water, as most serious environmental problem. Media has had an effect on students’ perceptions on environmental issues: when students perceived the problem as serious they also perceived the information in media concerning it appropriate. Students perceived that the media underestimate and obscure some environmental problems such as biological diversity and global warming. It was concluded that higher education educators need more knowledge of students’, future decision makers’ concerns and perceptions about environmental issues to develop more effective teaching practices in higher education. Through education environmental issues literacy, which is a precursor for engaged protection of the environment, can be fostered. This study offers some insights into higher education students’ perceptions of the media’s role in environmental issues.

  9. Advantages and difficulties of implementation of the international GNA standards in sustainable mining development. (Invited)

    Conflicts in the development of mining projects are now common between the mining proponents, NGO's and communities. These conflicts can sometimes be alleviated by early development of modes of communication, and a formal discussion format that allows airing of concerns and potential resolution of problems. One of the methods that can formalize this process is to establish a Good Neighbor Agreement (GNA), which deals specifically with challenges in relationships between mining operations and the local communities. It is a new practice related to mining operations that are oriented toward social needs and concerns of local communities that arise during the normal life of a mine, which can achieve sustainable mining practices in both developing and developed countries. The GNA project being currently developed at the University of Nevada, Reno in cooperation with the Newmont Mining Corporation has a goal to create an open company/community dialog that is based on the international standards and that will help identify and address sociological and environmental concerns associated with mining, as well as find methods for communication and conflict resolution. GNA standards should be based on trust doctrine, open information access, and community involvement in the decision making process. It should include the following components: emergency response and community communications; environmental issues, including air and water quality standards; reclamation and recultivation; socio-economic issues: transportation, safety, training, and local hiring; and financial issues, particularly related to mitigation offsets and community needs. The GNA standards help identify and evaluate conflict criteria in mining/community relationships; determine the status of concerns; focus on the local political and government systems; separate the acute and the chronic concerns; determine the role and responsibilities of stakeholders; analyze problem resolution feasibility; maintain the

  11. Object-oriented spatial-temporal association rules mining on ocean remote sensing imagery

    International Nuclear Information System (INIS)

    Xue, C J; Dong, Q; Ma, W X

    2014-01-01

    Using the long term marine remote sensing imagery, we develop an object-oriented spatial-temporal association rules mining framework to explore the association rules mining among marine environmental elements. Within the framework, two key issues are addressed. They are how to effectively deal with the related lattices and how to reduce the related dimensions? To deal with the first key issues, this paper develops an object-oriented method for abstracting marine sensitive objects from raster pixels and for representing them with a quadruple. To deal with the second key issues, by embedding the mutual information theory, we construct the direct association pattern tree to reduce the related elements at the first step, and then the Apriori algorithm is used to discover the spatio-temporal associated rules. Finally, Pacific Ocean is taken as a research area and multi- marine remote sensing imagery in recent three decades is used as a case study. The results show that the object-oriented spatio-temporal association rules mining can acquire the associated relationships not only among marine environmental elements in same region, also among the different regions. In addition, the information from association rules mining is much more expressive and informative in space and time than traditional spatio-temporal analysis

    2002-01-01

    Stringent environmental controls have been applied to the Ranger mine, in the Northern Territory of Australia, because of its location in an area of outstanding natural and cultural values. The adjacent Kakadu National Park contains a wild and extensive biodiversity, striking landscapes, ancient Aboriginal rock art and a living Aboriginal culture. A special regime of biological, radiological and chemical monitoring has been applied to protect the environment and detect even very low intensity impacts. The results from this regime demonstrate to the government and general public that the high conservation values of the national park around the mine are being properly protected. This paper describes the techniques used to measure environmental impact at Ranger, and summarizes the results of over 20 years of monitoring. The overwhelming conclusion is that a very high standard of environmental protection has been achieved. (author)

    2018-02-01

    Full Text Available While the mining industry is booming globally, local communities resist mining operations. It is crucial for mining companies to maintain trust within these communities to prevent conflicts. This research investigated local community’s trust in a mining company in Mongolia using a questionnaire survey. We assessed the residents’ perceptions of the company’s effort to maintain environmental protection, as a determinant of trust, in addition to the determinants of motivation and ability. The results showed that the trust level varied within the different respondent groups and the determinants of trust differentially explained the state of trust. The nomadic herders who lived close to the mine site had low trust while being sensitive to the environmental effects. Other herders had neutral trust. Town citizens had high trust, which was mainly related to positive perceptions of motivation. Communicability of the information provided by the company influenced formulation of positive and negative perceptions. Overall, low trust likely leads to conflicts. Therefore, mining companies are advised to conduct surveys with different groups in the local community, especially those sensitive to environmental changes, and take measures to maintain trust.

    2014-01-01

    facilities are performing as designed, the collection of baseline environmental data to objectively assess ecosystem impacts through the life of the mine by environmental monitoring programmes is essential to provide assurance of performance. Public consultation opportunities in presenting the results of the environmental monitoring programmes have proven critical to maintaining trust that the operations are performing as planned. Communication with neighbouring communities in decisions that affect them is critical to maintaining a social license to mine. An ongoing dialogue among the main stakeholders: the community, the mining company and the government has proven critical in this regard. With careful execution and participation of the main stakeholders, and adequate funding set aside for site remediation by mining companies, public funding for uranium mine site legacies and remediation should no longer be required and the goal of ensuring that no additional legacy uranium mining and milling issues are created will be assured. Included in this presentation are examples of public consultation in uranium mine operations that illustrate some of the challenges faced when undertaking public consultation and how such programmes can effectively increase public confidence and support of uranium mining, strengthening the social license to conduct the mining activity.

    2007-01-01

    Uranium ore was extracted in the surroundings of Mangualde city, North of Portugal, in the mines of Cunha Baixa, Quinta do Bispo and Espinho until a few years ago. Mining waste, milling tailings and acid mine waters are the on site remains of this extractive activity. Environmental radioactivity measurements were performed in and around these sites in order to assess the dispersal of radionuclides from uranium mining waste and the spread of acidic waters resulting from the in situ uranium leaching with sulphuric acid. Results show migration of acid waters into groundwater around the Cunha Baixa mine. This groundwater is tapped by irrigation wells in the agriculture area near the Cunha Baixa village. Water from wells displayed uranium ( 238 U) concentrations up to 19x10 3 mBq L -1 and sulphate ion concentrations up to 1070 mg L -1 . These enhanced concentrations are positively correlated with low water pH, pointing to a common origin for radioactivity, dissolved sulphate, and acidity in underground mining works. Radionuclide concentrations were determined in horticulture and farm products from this area also and results suggest low soil to plant transfer of radionuclides and low food chain transfer of radionuclides to man. Analysis of aerosols in surface air showed re suspension of dust from mining and milling waste heaps. Therefore, it is recommended to maintain mine water treatment and to plan remediation of these mine sites in order to prevent waste dispersal in the environment. (authors)

    2008-05-15

    Due to rapid industrialization and urbanization, the number of China's large proposed coal mines has increased very quickly in recent years. 144 environmental impact assessment reports were submitted to SEPA during 2001 2006, so the problem of reconciling coal exploitation with the environmental and social impacts has become urgent in China's sustainable development strategy. Based on analysis of data on coal mine exploitation, it is pointed out that there are four main problems in the management of the coal sector: the SEA (Strategic Environmental Assessment) lags behind the practical needs; the policy is not clear; migration is neglected; and an ecological compensatory mechanism is absent. Four countermeasures are recommended: accelerating the execution of SEA; compartmentalizing typical zones for environmental management; improving the organisation of resettlement in the coal district; and installing an ecological compensatory mechanism in the coal mining industry. 13 refs., 2 figs., 1 tab.

    Full Text Available Small scale mining continues to contribute significantly to the growth of Ghana's economy. However, the sector poses serious dangers to human health and the environment. Ground failures resulting from poorly supported stopes have led to injuries and fatalities in recent times. Dust and fumes from drilling and blasting of ore present health threats due to poor ventilation. Four prominent small scale underground mines were studied to identify the safety issues associated with small scale underground mining in Ghana. It is recognized that small scale underground mining in Ghana is inundated with unsafe acts and conditions including stope collapse, improper choice of working tools, absence of personal protective equipment and land degradation. Inadequate monitoring of the operations and lack of regulatory enforcement by the Minerals Commission of Ghana are major contributing factors to the environmental, safety and national security issues of the operations.

    A global and multi-faceted response to climate change is essential if meaningful and cost-effective progress is to be made in reducing the effects of climate change around the world. There is no doubt that the uranium mining sector has an important role to play in such a goal. Uranium is the raw material used to produce fuel for long-lived nuclear facilities, necessary for the generation of significant amounts of baseload low-carbon electricity for decades to come. Given expectations of growth in nuclear generating capacity and the associated uranium demand, enhancing awareness of leading practices in uranium mining is indispensable. Actors in the uranium mining sector operate in a complex world, throughout different geographies, and involving global supply chains. They manage climate-sensitive water, land and energy resources and balance the interests of various stakeholders. Managed well, uranium mining delivers sustainable value for economic growth, employment and infrastructure, with specific attention given to the preservation of the environment. In the early phases of the industry, however, downside risks existed, which created legacy environmental and health issues that still can be recalled today. This article addresses key aspects of modern uranium mining operations that have been introduced as regulations and practices have evolved in response to societal attitudes about health, safety and environmental protection. Such aspects of mine management were seldom, if ever, respected in the early stages of uranium mining. With the implementation of modern mine lifecycle parameters and regulatory requirements, uranium mining has become a leader in safety and environmental management. Today, uranium mining is conducted under significantly different circumstances and is now the most regulated and one of the safest forms of mining in the world. Experiences from modern uranium mines show that successful companies develop innovative strategies to manage all the

    On the framing of issues of conflicting civil rights under administrative law. The available arsenal of legal instruments for solving conflicts between proprietary titles to land surfaces and mines is more extensive and differentiated and, if properly deployed, more effective than one might at first expect. The control mechanisms become effective either immediately through laws or through administrative or private acts and are based on public or on private law. They range from the sphere of mining rights, operation planning law, the law on the prevention of damage to private persons over to the regulations under mining law on the payment of damages. The constitutionality of the mining regulations examined here is beyond dispute. They comply with the constitutional requirement to frame the issue concerned and afford protection while at the same time providing the required measure of openness and flexibility for conforming to the peculiarities of the mining business and permitting the necessary sensitivity of administrative control for managing this multipolar legal relationship. At the statutory level the regulatory purpose of the mining law in force is thus fulfilled. (orig./HSCH) [de

    Miller, M.J. [Electric Power Research Inst., Palo Alto, CA (United States)

    1997-12-31

    The author outlines what he considers to be the key environmental issues affecting Clean Coal Technology (CCT) deployment both in the US and internationally. Since the international issues are difficult to characterize given different environmental drivers in various countries and regions, the primary focus of his remarks is on US deployment. However, he makes some general remarks, particularly regarding the environmental issues in developing vs. developed countries and how these issues may affect CCT deployment. Further, how environment affects deployment depends on which particular type of clean coal technology one is addressing. It is not the author`s intention to mention many specific technologies other than to use them for the purposes of example. He generally categorizes CCTs into four groups since environment is likely to affect deployment for each category somewhat differently. These four categories are: Precombustion technologies such as coal cleaning; Combustion technologies such as low NOx burners; Postcombustion technologies such as FGD systems and postcombustion NOx control; and New generation technologies such as gasification and fluidized bed combustion.

    2000-01-01

    The current environmental impact of base metal mining at the Tui Mine, Te Aroha and gold mining near Waihi, was investigated by analysis of local waters, stream sediments and aquatic vegetation. X-ray diffraction analysis of heavy metal fractions in stream sediments showed the presence of pyrite in the upper reaches of the Tunakohoia and Tui streams that drain the mineralised reefs and Tui tailings dam. Relatively immobile lead (galena) was retained close to the source, whereas copper and zinc minerals were more mobile and distributed further downstream from the areas of mineralisation. Gold was determined in sediments from the Ohinemuri and Waitekauri Rivers along with other heavy metals derived from sulphide mineralisation at Waihi and Waitekauri. Analysis of waters from the Tui and Tunakohoia streams showed concentrations of arsenic, cadmium, lead and zinc above recommended levels for potable water in the upper parts of these waterways. The discharge of these streams into the Waihou River (sampled upstream from Te Aroha and downstream past Paeroa) did not have any significant effect on heavy-metal concentrations in this river. Aquatic macrophytes sampled in the Waihou, Ohinemuri and Waitekauri Rivers had very high heavy-metal concentrations compared with the ambient water and should be considered as potentially useful for assessing the impact of low-metal fluxes into the waters. Gold was detected in aquatic marcophytes from streams draining both the Martha Mine at Waihi and the Golden Cross Mine at Waitekauri and indicated the possibility of prospecting for gold by analysis of these plants.

    Full Text Available The paper analyzes the impacts of mining activities on sustainable land management in mining areas in the Republic of Serbia and Romania and discusses the main challenges related to the management of these issues in legislation and practice. Particular attention is paid to land disturbance, mine waste management and land reclamation, as well as access to land for mining purposes, the transfer of mining royalties and the partnerships of the mining industry, governments, communities and civil society for sustainable mining. Both governments are willing to provide the adequate role to mining in strengthening the national economies, but they face numerous constraints in this matter. Sustainable mining practices and consistent implementation of the mining for the closure planning approach, within an improved legislative framework and in cooperation with stakeholders at all levels, create conditions for the development of creative, profitable, environmentally-sound and socially-responsible management and reuse of mine lands.

    This study was carried out to investigate the problems such as mine drainage, mine wastes, subsidence and existence of facilities at the abandoned metallic mines and to evaluate the reactor system for acid mine drainage treatment in the field. According to the field investigation, the remediation was necessary for abandoned mines such as the Taechang, the Imcheon, the Kubong, the Cheongyang, the Cheonbo(Jungyang), the Seojeom, the Kuryong and the Ilkwang mines. Comparing analytical data with soil environmental reservation law, main components to contaminate soil environment in the vicinity of the abandoned mining areas, were As, Cd, Pb and cyanide. Results of chemical analysis for mine drainage showed that As Cd, Cu, Mn, Zn, Cr{sup 6+}, Fe and pH were major pollutants to the water environment and over level of discharge, water quality environment reservation law. The reactor with cow manure removed the metals such as Fe, Cu, Zn, Cd, Pb and Al by 100%. It was evaluated that the metal removal in the reactor was due to sulfate reduction and hydrolysis. In addition, acid mine drainage was neutralized to over pH 5 during 100 days. (author). 12 refs., 25 tabs., 23 figs.

    Problems in the post-mining regions of Eastern Europe range from degraded land and landscapes, huge insecure dumps, surface cracks, soil pollution, lowering groundwater table, deforestation, and damaged cultural potentials to socio economic problems like unemployment or population decline. There is no common prescription for tackling the development of post-mining regions after mine closure nor is there a common definition of good practices or policy in this field. Key words : waste management, legislation, EU Directive, post mining Rosia Montana is a common oh 16 villages; one of them is also called Rosia Montana, a traditional mining Community, located in the Apuseni Mountains in the North-Western Romania. Beneath part of the village area lays one of the largest gold and silver deposits in Europe. In the Rosia Montana area mining had begun ever since the height of the Roman Empire. While the modern approach to mining demands careful remediation of environmental impacts, historically disused mines in this region have been abandoned, leaving widespread environmental damage.

    Liu, Wenying; Moran, Chris J; Vink, Sue

    2011-09-01

    The potential environmental threats posed by freshwater withdrawal and mine water discharge are some of the main drivers for the mining industry to improve water management. The use of multiple sources of water supply and introducing water reuse into the mine site water system have been part of the operating philosophies employed by the mining industry to realize these improvements. However, a barrier to implementation of such good water management practices is concomitant water quality variation and the resulting impacts on the efficiency of mineral separation processes, and an increased environmental consequence of noncompliant discharge events. There is an increasing appreciation that conservative water management practices, production efficiency, and environmental consequences are intimately linked through the site water system. It is therefore essential to consider water management decisions and their impacts as an integrated system as opposed to dealing with each impact separately. This paper proposes an approach that could assist mine sites to manage water quality issues in a systematic manner at the system level. This approach can quantitatively forecast the risk related with water quality and evaluate the effectiveness of management strategies in mitigating the risk by quantifying implications for production and hence economic viability.

    1995-01-01

    Environmental radiological monitoring in the vicinity of uranium mining and milling plants in Argentina is performed on a routine basis, in order to assess the possibility of significant environmental contamination due to uranium mill wastes and mill tailings of plants still operating or those where the exploitation have concluded. Dissolved natural uranium and 226 Ra concentrations in surface waters are measured in samples taken from rivers near the mills, according to a special monitoring plan set up for each facility. In addition, 222 Rn emanation rates from ore tailings are measured at times. In this paper the environmental radiological monitoring program results obtained for the 1980-1994 period are shown. From the data analyses it can be concluded that there are not significant differences for the concentrations of the radionuclides of interest, between the surface water samples taken from river location above and below the plants discharge points. Besides, no significant exposure results for the population living in the surrounding areas due to the uranium mining and milling plants operation or their wastes. (author). 2 refs., 5 figs

    Full Text Available Acid mine drainage (AMD is recognized as one of the most serious environmental problem associated with mining industry. Acid water, also known as acid mine drainage forms when iron sulfide minerals found in the rock of coal seams are exposed to oxidizing conditions in coal mining. Until 2009, mine drainage in Hongai coal mines was not treated, leading to harmful effects on humans, animals and aquatic ecosystem. This report has examined acid mine drainage problem and techniques for acid mine drainage treatment in Hongai coal mines. In addition, selection and criteria for the design of the treatment systems have been presented.

    The purpose of this research is to establish an environmental management zoning for coal mining industry which is served as a basis for making environmental management policies. Based on the specific impacts of coal mining and regional characteristics of environment and resources, the ecological impact, water resources impact, and arable land impact are chose as the zoning indexes to construct the index system. The ecological sensitivity is graded into three levels of low, medium, and high according to analytical hierarchy processes and gray fixed weight clustering analysis, and the water resources sensitivity is divided into five levels of lower, low, medium, high, and higher according to the weighted sum of sub-indexes, while only the arable land sensitive zone was extracted on the basis of the ratio of arable land to the county or city. By combining the ecological sensitivity zoning and the water resources sensitive zoning and then overlapping the arable-sensitive areas, the mainland China is classified into six types of environmental management zones for coal mining except to the forbidden exploitation areas.

    This study is focused on the impacts of metalliferous mines on the environment in the vicinity of the abandoned and active mines and establishment of abatements of mining environmental problems. Total number of metalliferous mines surveyed were 40 in which samples of waters, mine wastes and soil were taken. Water parameters such as the pH, Eh, TDS, conductivity, turbidity, dissolved oxygen and temperature were measured in the field. Elements such as As, Cd, Pb, Zn, Cu, Al, Mn, sulfate and cyanide were analyzed. Significant concentrations of heavy metals, mainly Cd, Zn, Cu, Fe, Mn and Al, were found in mine waters from adit and in leachates extracted from mine wastes. The mine waters flowing out from the Dalsung and Ilgwang mines were the typical acid mine drainage(AMD) contaminated by the heavy metals. Passive biological systems(Anoxic wetland) to treat AMD for metals were designed and monitored for effluents from the reactors with 4 types of composts, cow manure and limestones, Results showed that the mushroom compost with cow manure and limestone was the best substrates in metal removing efficiencies. Results from leaching of mine wastes showed that As, Cd and Cu were extracted from some of mine wastes. AMD from the mine waste dump of the Daduk mine was found. These mean that mine wastes can contaminate the soil, surface water and ground waters in vicinity of mines. Therefore cover systems or liner system for containments of mine wastes were suggested to preserve the environment. Cu and As concentrations in soils surveyed were below the heavy metal concentrations in soils of Korean standard preventing plant of the crops. However, most of the acid mine waters are drained untreated, and mine wastes with heavy metals are distributed near soil environment. Therefore efforts to reduce possibilities of soil contamination in the vicinity of mining areas is required. (author). 33 refs.

    2009-06-01

    Traditional hazards such as poor sanitation currently account for most of Africa's environmentally related disease burden. However, with rapid development absent appropriate safeguards for environment and health, modern environmental health hazards (MEHHs) may emerge as critical contributors to the continent's disease burden. We review recent evidence of human exposure to and health effects from MEHHs, and their occurrence in environmental media and consumer products. Our purpose is to highlight the growing significance of these hazards as African countries experience urbanization, industrial growth, and development. We reviewed published epidemiologic, exposure, and environmental studies of chemical agents such as heavy metals and pesticides. The body of evidence demonstrates ongoing environmental releases of MEHHs and human exposures sometimes at toxicologically relevant levels. Several sources of MEHHs in environmental media have been identified, including natural resource mining and processing and automobile exhaust. Biomonitoring studies provided direct evidence of human exposure to metals such as mercury and lead and pesticides such as p,p'-dichlorodiphenyltrichloroethane (DDT) and organophosphates. Land and water resource pollution and industrial air toxics are areas of significant data gaps, notwithstanding the presence of several emitting sources. Unmitigated MEHH releases and human exposure have implications for Africa's disease burden. For Africans encumbered by conditions such as malnutrition that impair resilience to toxicologic challenges, the burden may be higher. A shift in public health policy toward accommodating the emerging diversity in Africa's environmental health issues is necessary to successfully alleviate the burden of avoidable ill health and premature death for all its communities now and in the future.

    2016-04-01

    With recent advancements in technology and rising standards of living the demand for minerals has increased drastically. Increased reliance on mining industry has led to unmanageable challenges of Mining waste generated out of Mining and Quarrying activities. According to Statistics from EuroStat Mining and Quarrying generated 734 million Tons in Europe in 2012 which accounted for 29.19 % of the total waste, becoming second most important sector in terms of waste generation after Construction Industry. Mining waste can be voluminous and/ or chemically active and can cause environmental threats like groundwater pollution due to leaching of pollutants, surface water pollution due to runoffs during rainy season, river and ocean pollution due to intentional dumping of tailings by mining companies. Most of the big mining companies have not adopted policies against dumping of tailings in rivers and oceans. Deep Sea Tailings Placement (DSTP) is creating havoc in remote and pristine environment of deep-sea beds e.g. Bismarck Sea. Furthermore, mining waste is contaminating soil in nearby areas by disturbing soil microbial activity and other physio-chemical and biological properties of soil (e.g. Barruecopardo village - Spain). Mining waste stored in heaps and dams has led to many accidents and on an average, worldwide, there is one major accident in a year involving tailings dams (e.g. Myanmar, Brazil, 2015). Pollution due to tailings is causing local residents to relocate and become 'ecological migrants'. The above issues linked to mining waste makes reuse and securing of mining waste one of the urgent challenge to deal with. The studies done previously on mining show that most of the researches linked with mining waste reuse and securing are very site specific. For instance, the type of recovery method should not only provide environmental clean-up but also economic benefits to promise sustainability of the method.

    Assessment of soil quality is one of the key parameters for evaluation of environmental contamination in the mining ecosystem. To investigate the effect of coal mining on soil quality, opencast and underground mining sites were selected in the Raniganj coalfield area, India. The physical, chemical, and biological parameters of the soils, and trace metals and PAHs (polycyclic aromatic hydrocarbons) in the soils were evaluated. Soil dehydrogenase (+79 %) and fluorescein (+32 %) activities were significantly higher in underground mine (UGM) soil, whereas peroxidase activity (+57 %) was higher in opencast mine (OCM) soil. Content of As, Be, Co, Cr, Cu, Mn, Ni, and Pb was significantly higher in OCM soil, whereas Cd was higher in UGM. In general, the PAHs contents were higher in UGM soils, probably due to the natural coal burning at these sites. The observed values for the above properties were converted into a unitless score (0-1.00) and the scores were integrated into an environmental soil quality index (ESQI). In the unscreened index (ESQI-1) all the soil parameters were included and the results showed that the quality of the soil was better for UGM (0.539) than the OCM (0.511) soils. Principal component analysis was employed to derive ESQI-2 and accordingly, total PAHs, loss on ignition, bulk density, Be, Co, Cr, Ni, Pb, and microbial quotient (respiration: microbial biomass ratio) were found to be the most critical properties. The ESQI-2 was also higher for soils near UGM (+10.1 %). The observed indicators and the ESQI results revealed that soil quality assessment for these coal mining soils is largely depended on soil PAHs and potentially toxic trace metals. The proposed ESQI may be further refined by incorporating specific parameters related to human exposure risks and exposure pathways.

    Although the gold demand has been constantly increasing in past years, the commodity findings have been decreasing and the extraction of gold has complicated due to increasing complexity and decreasing grade of the ores. Additionally, even gold mining could increase economical development, it has also challenges in eco-efficiency and extraction methods (e.g. cyanide). Thus, the novel energy and resource-efficient methods and technologies for mineral processing should be developed to concentrate selectively different gold bearing minerals. Furthermore, technologies for efficient treatment of mine waters, sustainable management of wastes, and methods to diminish environmental and social impacts of mining are needed. These problems will be addressed by the three year long project SUSMIN. The SUSMIN-project identifies and evaluates environmental impacts and economical challenges of gold mining within EU. The objective of the project is to increase the transnational cooperation and to support environmentally, socially and economically sustainable viable gold production. The focus is to develop and test geophysical techniques for gold exploration, eco-efficient ore beneficiation methods and alternatives for cyanide leaching. Additionally, the research will improve treatment methods for mine waters by the development and testing of advanced adsorbents. The research on socio-economic issues pursues to develop tools for enhancing the mechanisms of the corporate social responsibility as well as community engagement and management of the relations with the stakeholders. Moreover, with the environmental risk assessment and better knowledge of the geochemistry and long-term transformation of the contaminants in mining wastes and mine waters, the mining companies are able to predict and prevent the impacts to the surrounding environment, resulting in an improved environmental management solution. The SUSMIN consortium led by Geological Survey of Finland (GTK) includes seven

    European mining industries are the vast industrial sector which contributes largely on their economy which constitutes of ferro and non-ferro metals and minerals industries. The non-ferro metals extraction and processing industries require focus of attention due to sustainability concerns as their manufacturing processes are highly energy intensive and impacts globally on environment. This paper analyses major environmental effects caused by European metal industries based on the life-cycle impact analysis technologies. This research work is the first work in considering the comparative environmental impact analysis of European non-ferro metal industries which will reveal their technological similarities and dissimilarities to assess their environmental loads. The life-cycle inventory datasets are collected from the EcoInvent database while the analysis is done using the CML baseline and ReCipe endpoint method using SimaPro software version 8.4. The CML and ReCipe method are chosen because they are specialized impact assessment methods for European continent. The impact categories outlined for discussion here are human health, global warming and ecotoxicity. The analysis results reveal that the gold industry is vulnerable for the environment due to waste emission and similar result retained by silver mines a little bit. But copper, lead, manganese and zinc mining processes and industries are environment friendly in terms of metal extraction technologies and waste emissions.

    Understanding a community’s concerns and informational needs is crucial to conducting and improving environmental health research and literacy initiatives. We hypothesized that analysis of community inquiries over time at a legacy mining site would be an effective method for assessing environmental health literacy efforts and determining whether community concerns were thoroughly addressed. Through a qualitative analysis, we determined community concerns at the time of being listed as a Superfund site. We analyzed how community concerns changed from this starting point over the subsequent years, and whether: 1) communication materials produced by the USEPA and other media were aligned with community concerns; and 2) these changes demonstrated a progression of the community’s understanding resulting from community involvement and engaged research efforts. We observed that when the Superfund site was first listed, community members were most concerned with USEPA management, remediation, site-specific issues, health effects, and environmental monitoring efforts related to air/dust and water. Over the next five years, community inquiries shifted significantly to include exposure assessment and reduction methods and issues unrelated to the site, particularly the local public water supply and home water treatment systems. Such documentation of community inquiries over time at contaminated sites is a novel method to assess environmental health literacy efforts and determine whether community concerns were thoroughly addressed.

    2010-01-01

    There has been an increasing body of knowledge with regard to hydro- and geochemical alteration processes in overburden dumps and their impact on groundwater quality in lignite mining and reclamation operations associated with post-mining landscapes in Germany. The operators of the MIBRAG mines have examined issues regarding alteration processes and how they affect the environment and which opportunities exist to actively influence the dumping process. The objectives were to counteract any possible negative impact of the alteration processes. Special emphasis was on the impact caused by oxidation of sulfur containing minerals. This paper presented an analysis of the situation at United Schleenhain Mine and how it reflects on the work to date for MIBRAG's mines. A future outlook was also presented. Specifically, the paper discussed the development of the United Schleenhain mine and the post-mining landscape. The potential for discharge of substances was also evaluated along with acidification. 1 tab., 5 figs.

    The objective of this project was to host BioCreative workshops to define and develop text mining tasks to meet the needs of the Genome Sciences community, focusing on metadata information extraction in metagenomics. Following the successful introduction of metagenomics at the BioCreative IV workshop, members of the metagenomics community and BioCreative communities continued discussion to identify candidate topics for a BioCreative metagenomics track for BioCreative V. Of particular interest was the capture of environmental and isolation source information from text. The outcome was to form a “community of interest” around work on the interactive EXTRACT system, which supported interactive tagging of environmental and species data. This experiment is included in the BioCreative V virtual issue of Database. In addition, there was broad participation by members of the metagenomics community in the panels held at BioCreative V, leading to valuable exchanges between the text mining developers and members of the metagenomics research community. These exchanges are reflected in a number of the overview and perspective pieces also being captured in the BioCreative V virtual issue. Overall, this conversation has exposed the metagenomics researchers to the possibilities of text mining, and educated the text mining developers to the specific needs of the metagenomics community.

    2002-01-01

    The regulatory framework issued in the 1994-1995 period, connected mining activities in Argentina with international good environmental practices. Agreements between National Government and Provinces allow the application of the regulations, while Act No 24.585, the milestone about the matter, establishes the steps for the approval of the Report of Environmental Impact, on successive stages of the project. Specifically for uranium mining and milling, the assessment of the radiological protection aspects of the planned activities is assigned to the Nuclear Regulatory Authority. The National Atomic Energy Commission is at present carrying out two uranium mining projects, that involve the Sierra Pintada and Cerro Solo deposits. The goal of them is restart uranium production in the country in the medium term, by lowing the gap between indigenous and market uranium prices. The first one consists in updating the feasibility study of the, at present inactive, Sierra Pintada Production Center (Mendoza Province). Studies for improving the mining and treatment methods are performed in the project, co-ordinately with the investigation and forecast of mining waste and processing tailings management. Besides, the procedures will be determined taking into account the methodology to be applied when getting the closure stage, about the existing waste and tailings. Development of the Sierra de Pichinan District, Chubut Province (U-Mo), is the objective of the second project. It is remarkable that about Cerro Solo, the main ore deposit belonging to this area, at the prefeasibility stage, CNEA is currently encouraging private investment through a bidding process. Environmental studies are an important aspect of the activities carried out and planned in the area. As a conclusion, with regard uranium mining and milling activities in Argentina, the regulations and environmental technical-scientific knowledge are becoming friendly with the sustainable practice.

    Chamaret, A.

    2007-06-01

    This thesis aims to appraise the relevance of using an hybrid top-down / bottom-up approach to evaluate mining projects in the perspective of sustainable development. With the advent of corporate social responsibility and sustainable development concepts, new social expectations have appeared towards companies that go beyond a sole requirement of profit earning capacity. If companies do not answer to these expectations, they risk to lose their social legitimacy. Traditionally associated with social, environmental, economical and political impacts and risks, mining activity is particularly concerned by these new issues. Whereas mineral resources needs have never been so high, mining companies are now expected to limit their negative effects and to take into account their different audiences' expectations in order to define, together, the terms of their social license to operate. Considering the diversity of issues, scales, actors and contexts, the challenge is real and necessitates tools to better understand issues and to structure dialogues. Based on the Uranium mines of Arlit (Niger) case study, this work shows that associating participatory approaches to structuration tools and literature propositions, appears as an efficient formula to better organize issues diversity and to build a structured dialogue between mining companies and their stakeholders. First Part aims to present the theoretical, institutional and sectorial contexts of the thesis. Second Part exposes work and results of the evaluation carried out in Niger. And, Third Part, shows the conclusions that can be derived from this work and presents a proposal for an evaluation framework, potentially applicable to other mining sites. (author)

    Mining at Middelburg Colliery in the Witbank Coalfield commenced at the turn of the last century. Initially, there was little environmental degradation associated with mining activities; however, in the late 1930s, a pillar-robbing programme commenced. This has had a marked effect on the environment. Some of the most notable primary effects include subsidence, the appearance of tension cracks at the surface and crownhole development. Secondary effects include spontaneous combustion of the coal worked, as air has been provided with ready access to the mine, accelerated subsidence due to the strength of many pillars being reduced by burning, and a marked deterioration of groundwater quality in the area due to the seepage of acid mine drainage from the mine. Spoil heaps also form blemishes on the landscape. These contain significant amounts of coal and have undergone spontaneous combustion. The deterioration in the quality of water has led to the decimation of vegetation in some areas and the eradication of aquatic flora and fauna in a nearby stream

    2007-01-01

    The present research is focused on the contribution of base-metal mining to heavy metal contamination of the environment. Mining wastes and unworked ore-mineral concentrations present in the Keban region (eastern Turkey) are the main sources of environmental contamination in the area via leaching of the potentially toxic elements. Total-element concentrations of several different sampling media, such as sediment, waters and plants were measured. Analyses of metal and metalloid concentrations of sediment samples indicate high As, F, Mo and Zn contents, which decrease exponentially with distance from the mine and mineralized zones, mainly due to dilution by water and barren material. The average concentrations of As, Cd, Cr, Pb and Ta in the water samples are higher than the average natural background values for these heavy metals. The most significant components of water samples under study are (>1 mg/1) Ca, Cl, K, Mg, Mn, Na, Zn and S and (1 mg/1) Ba, Fe and Mo; these samples are also enriched in some toxic elements such as As, Cd, Cr, Pb and Sb. Red algae have a higher capacity for absorption of Cr, Cu, Mn,Ni, Pb and S, whereas green algae are enriched in Co, Hg, La, Se and V. However, the highest heavy-metal and toxic element contents are found in moss collected at the mine adit. (author)

    1994-01-01

    It is natural in a democratic society that people request more participation in the decision making process. The once centralized government was however reluctant to open more room in this regard concerning the nuclear power industry and radioactive waste management. The environmental impact assessment provided the statuary ground, although limited, for public participation in the environmental issues. A comprehensive social communication program which consists of public information, public education, public relation, and public participation must be established to ensure the smooth realization of a development project. This paper described the relevant situations in Taiwan and recommended various practices to alleviate the NIMBY syndrome. These descriptions and recommendations would be useful particularly for the third world countries facing emerging environmental issues in the near future

    China has the largest coal production in the world due to abundant resource requirements for economic development. In recent years, the proportion of opencast coal mine production has increased significantly in China. Opencast coal mining can lead to a large number of environmental problems, including air pollution, water pollution, and solid waste occupation. The previous studies on the environmental impacts of opencast coal mine production were focused on a single production process. Moreover, mined land reclamation was an important process in opencast coal mine production; however, it was rarely considered in previous research. Therefore, this study attempted to perform a whole environmental impact analysis including land reclamation stage using life cycle assessment (LCA) method. The Yimin opencast coal mine was selected to conduct a case study. The production of 100 tons of coal was used as the functional unit to evaluate the environmental risks in the stages of stripping, mining, transportation, processing, and reclamation. A total of six environmental impact categories, i.e., resource consumption, acidification, global warming, solid waste, eutrophication, and dust, were selected to conduct this assessment. The contribution rates of different categories of environmental impacts were significantly different, and different stages exhibited different consumption and emissions that gave rise to different environmental effects. Dust was the most serious environmental impact category, and its contribution rate was 36.81%, followed by global warming and acidification with contribution rates of 29.43% and 22.58%, respectively. Both dust and global warming were mainly affected in mining stage in Yimin opencast coal mine based on comprehensive analysis of environmental impact. Some economic and feasible measures should be used to mitigate the environmental impacts of opencast coal mine production, such as water spraying, clean transportation, increasing processing

    Environmental justice (EJ) research seeks to document and redress the disproportionate environmental burdens and benefits associated with social inequalities. Although its initial focus was on disparities in exposure to anthropogenic pollution, the scope of EJ research has expanded. In the context of intensifying social inequalities and environmental problems, there is a need to further strengthen the EJ research framework and diversify its application. This Special Issue of the International Journal of Environmental Research and Public Health (IJERPH) incorporates 19 articles that broaden EJ research by considering emerging topics such as energy, food, drinking water, flooding, sustainability, and gender dynamics, including issues in Canada, the UK, and Eastern Europe. Additionally, the articles contribute to three research themes: (1) documenting connections between unjust environmental exposures and health impacts by examining unsafe infrastructure, substance use, and children's obesity and academic performance; (2) promoting and achieving EJ by implementing interventions to improve environmental knowledge and health, identifying avenues for sustainable community change, and incorporating EJ metrics in government programs; and (3) clarifying stakeholder perceptions of EJ issues to extend research beyond the documentation of unjust conditions and processes. Collectively, the articles highlight potentially compounding injustices and an array of approaches being employed to achieve EJ.

    Full Text Available Artisanal mining is associated with a number of environmental impacts, including deforestation and land degradation, open pits which pose animal traps and health hazards, and heavy metals contamination of land (water and soil, dust and noise pollution. The study examines the perception of environmental degradation of gold mining sites in eastern Cameroon. Human-environment interaction and distance decay models are the conceptual framework for this study.  This study employed a survey research design through the use of primary data while a purposive sampling technique was utilized. A total of 440 questionnaires were administered to selected households across the localities in the study area. Frequencies, percentages, chart, cross tabulations and chi-square tests were used for the data analysis. In other to achieve the aim of this study, a comparison between the nearby and far away residents were done. The study revealed that mining exploitations have brought about changes in the colour and taste of water in the active mining sites (41.7%. Malaria is the number one type of disease that has caused more damage in the localities (81.6%. Mining activities have successfully enabled children in the active mining sites to abandoned school for mining (75.0%. Inhabitants of unit 1 directly linked the problems facing their economic activities to inadequate arable land for agriculture (33.8% and inhabitants across the study area correlated the problems facing livestock farming to diseases as a result of mining activities (64.6%. The perceived negative effects of gold mining on different socio-economic variables (such as culture, health, education, economy and livestock vary significantly depending on the proximity from the mining areas (p<0.05. The study concludes that residents living within and far away from the active mining sites were affected by gold mining activities. However, the most worrisome situation concern people working and living within the

    2013-03-01

    Full Text Available This work analyzed and compared three methods of environmental recovery in bauxite mining commonly used in Poços de Caldas Plateau, MG, by means of recovery costs and ecological benefits. Earnings and costs data of environmental recovery activities were obtained for the areas that belonged to the Companhia Geral de Minas – CGM, on properties sited in the city of Poços de Caldas, MG. The amount of costs of these activities was used to compare the recovery methods by updating them monetarily to a reference date, in other words, the present moment. It is concluded that the difference between the present value of costs for simple restoration and rehabilitation activities are less than 1% and that between the complete restoration and rehabilitation is about 15.12%, suggesting that the choice of the methods to be used must be based on the ecological earnings proportional to each of them. The methodology of environmental restoration of the mining areas emphasizes the ecological variables in the process of establishment of the community, to the detriment of complex ecological aspects, which show difficulties in measuring the actual moment of the development of the ecosystem considered.

  14. Perception versus reality: Bridging the gap between quantitative and qualitative information relating to the risks of uranium mining

    2002-01-01

    Environmental impact of uranium mining in Australia is frequently raised as an issue of public concern. However, the level of concern both in terms of public agitation and political response has diminished over the last decade, largely as a consequence of many years of demonstrated high levels of environmental protection achieved at Australian uranium mines. Another reason is because of improved information now accessible to the public on mine environmental management systems, monitoring results, and audit outcomes. This paper describes some communication methods developed for the uranium mines of the Alligator Rivers Region of the Northern Territory. These methods have improved the effectiveness of dialogue between stakeholders, and better inform the public about the levels of environmental protection achieved and the level of risk to the environment and the community. A simple approach is described which has been developed to help build a mutual understanding between technocrats and the lay person on perceptions of risk and actual environmental impact. (author)

    The objective of this program was to conduct an environmental impact assessment study for selenium from coal mine spoils. The use of in-situ lysimetry to predict selenium speciation, transformation, and mobility under natural conditions was evaluated. The scope of the study was to construct and test field-scale lysimeter and laboratory mini-column to assess mobility and speciation of selenium in coal mine overburden and soil systems; to conduct soil and groundwater sampling throughout the state of Oklahoma for an overall environmental impact assessment of selenium; and to conduct an in-depth literature review on the solubility, speciation, mobility, and toxicity of selenium from various sources. Groundwater and surface soil samples were also collected from each county in Oklahoma. Data collected from the lysimeter study indicated that selenium in the overburden of the abandoned mine site was mainly found in the selenite form. The amount of selenite found was too low and immobile to be of concern to the environment. The spoil had equilibrated long enough (over 50 years) that most of the soluble forms of selenium have already been lost. Examination of the overburden indicated the presence of pyrite crystals that precipitated over time. The laboratory mini-column study indicated that selenite is quite immobile and remained on the overburden material even after leaching with dilute acid. Data from groundwater samples indicated that based on the current permissible level for selenium in groundwater (0.01 mg Se/L), Oklahoma groundwater is widely contaminated with the element. However, according to the new regulation (0.05 mg Se/L), which is to be promulgated in 1992, only 9 of the 77 counties in the state exceed the limit.

    Energy Resource of Australia (ERA) is a public company with 68% of its shares owned by the Australian company North Limited. It is currently operating one major production centre - Ranger Mine which is 260 kilometres east of Darwin, extracting and selling uranium from the Ranger Mine in the Northern Territory to nuclear electricity utilities in Japan, South Korea, Europe and North America. The first drum of uranium oxide from Ranger was drummed in August 1981 and operations have continued since that time. ERA is also in the process of working towards obtaining approvals for the development of a second mine - Jabiluka which is located 20 kilometres north of Ranger. The leases of Ranger and Jabiluka adjoin. The Minister for the Environment has advised the Minister for Resources and Energy that there does not appear to be any environmental issue which would prevent the preferred Jabiluka proposal from proceeding. Consent for the development of ERA's preferred option for the development of Jabiluka is being sought from the Aboriginal Traditional Owners. Ranger is currently the third largest producing uranium mine in the world producing 4,237 tonnes of U 3 O 8 in the year to June 1997

    Many industries have established their own systems for self-regulation. They often do so when companies involved in the industry operate in countries where financial, technical, environmental and social regulation is weak and when the industry is challenged by legitimacy issues related to behaviour...... in one of these areas. One industry that has progressed unevenly down the road of self-regulation in these areas is mining. Developing self-regulation for mines and mining companies involves difficult questions of scope, rules, membership, assessment criteria and performance evaluation. While self-regulation...... may bring benefits to members, they are likely to take a long time coming; but when they do arrive they may be substantial.

    The three principal activities of the mineral resources mining industry - mining, mineral processing and metallurgical extraction - all produce waste. The environmental impact of these activities depends on many factors, in particular, the type of mining and the size of the operation. The effects of the mining (extraction) stage tend to be mainly local, associated with surface disturbance, the production of large amounts of solid waste material, and the spread of chemically reactive particulate matter to the atmosphere and hydrosphere. Many studies have shown the potential of remote sensing for environmental impact monitoring, e.g., [1]. However, its applicability has been limited due to the inherent spatial-spectral and temporal trade-off of most sensors. More recently, miniaturization of sensors makes it possible to capture color images from unmanned aerial systems (UAS) with a very high spatial resolution. In addition, the UAS can be deployed in a very flexible manner, allowing high temporal resolution imaging. More detailed spectral information is available from multispectral images, albeit at lower spatial resolution. Combining both types of images using image fusion can help to overcome the spatial-spectral trade-off and provide a new tool for more detailed monitoring of environmental impacts. Within the framework of the ImpactMin project, funded by the Framework Programme 7 of the European Commission, the objective of this study is to implement and apply the spatial unmixing algorithm, as proposed by [2], on images of the 'Vihovici Coal Mine' area, located in the Mostar Valley, Bosnia and Herzegovina. A WorldView2 (WV2) satellite image will be employed, which provides 8-band multispectral data at a spatial resolution of 2m. High spatial resolution images, obtained by a SmartPlanes UAS, will provide RGB data with 0.05m spatial resolution. The spatial unmixing technique is based on the idea that a linear mixing model can be used to perform the downscaling of

    significant rise in global sea level over the coming decades. Most governments recognize the local impacts of sand mining and mining activities are illegal in many localities. However, enforcement of these protections has been problematic and there has been little pressure to stop the practice from local or international environmental groups. In many cases, addressing the issue of sand mining requires addressing the local issues that allow it to persist. This includes poverty, corruption, and unregulated development. In areas where beach sand mining significantly supports the local economy, care needs to be given that local workers are given alternative means of income, and builders are provided an affordable substitute for the sand (e.g. crushed rock). Regardless, it is time for both academics and NGOs to address the cumulative environmental impacts of the direct destruction of the world's beaches through mining activities.

    Mining activity and the other branches of heavy industry existing in the USCB for over 2 centuries have made large unfavourable changes of environment. Prevention of its further degradation needs the solution for the following main problems: utilisation of high saline mine drainage water (a problem unique in the world scale), treatment of solid wastes, land reclamation (mainly treatment of areas of ground subsiding). Market economy introduced 10 years ago and the necessity that all fields of life conform to the requirements of the European Union force the process of deep restructurisation of mining industry. One of the conditions for success of restructuring is the solution of ecological problems. The possibility of environmental management system implementation according to the ISO 14000 standard in the coal mine group condition was discussed. The chances and presumed results of these activities were presented in this paper. 6 refs

    International Nuclear Information System (INIS)

    Lambert, G.

    1999-01-01

    The environmental challenges facing the oil sand industry in Alberta are discussed, including the cumulative effects to air, water quality, aquatic ecosystems, soils, vegetation, wildlife, human health and traditional land use. Each of these concerns are briefly reviewed, using Suncor's announced developments as the background. Although ground level excesses of SO 2 and NO x are not expected to be an issue, there are concerns about acidification. Soils and sensitive water bodies can potentially be affected by acid deposition as a result of SO 2 and NO x emissions. Historical ozone monitoring has shown that peak hourly ozone levels have not exceeded air quality guidelines in the last five years in either Fort McKay or Fort McMurray. The conclusion is that environmental impacts are manageable, but predictions based on environmental assessment should be monitored, and if necessary, corrective action be taken. The recent spate of multi-stakeholder collaborative projects such as the Regional Aquatic Monitoring Program (RAMP), the Canadian Oil Sands Network for Research and Development (CONRAD), and the Regional Air Quality Coordinating Committee (RAQCC) collectively do a very good job of ensuring responsible management of environmental and socio-economic issues. An environmental management system model structured with a regional board representing various stakeholders with a number of technical issue groups reporting to the Board has been proposed. The proposed model is now under assessment by the Cumulative Environmental Effects Management Initiative (CEEM), a group that includes aboriginal groups, federal, provincial, and municipal governments, environmental groups and regional resource industries

  16. Coal mining and agriculture: a study in environmental impact assessment. [On agriculture in UK

    Energy Technology Data Exchange (ETDEWEB)

    Selman, P.H.

    1986-03-01

    Coal mining activities in the U.K. are reported to be extending into areas of comparatively unspoilt countryside. Despite reductions in the National Coal Board's programme of future expansion, it is considered that the scale of impact of new mining activities on agriculture is still likely to be significant. The major impact will be associated with land alienation, but a wide range of other adverse effects will also be encountered. In view of the controversy likely to accompany new mining proposals, it is recommended that methods of environmental impact assessment (EIA) should be adopted. The nature and components of EIA are reviewed, and a framework appropriate to mining-agriculture conflicts is advanced. This approach is more closely examined In relation to recent developments in Leicestershire, U.K. It is found that the magnitude of agricultural impact is small in national terms, but may be severe at the local and - if mining activities become geographically concentrated - even at the sub-regional level. Systematic scrutiny of major coaling proposals by EIA will therefore become essential. (115 refs.)

    2013-01-01

    Given the current insatiable demand for coal to build and fuel the world's burgeoning cities the debate about mining-related social, environmental and health injustices remains eminently salient. Furthermore, the core issues appear universally consistent. This paper combines the theoretical base for defining these injustices with reports in the international health literature about the impact of coal mining on local communities. It explores and analyses mechanisms of coal mining related injustice, conflicting priorities and power asymmetries between political and industry interests versus inhabitants of mining communities, and asks what would be required for considerations of health to take precedence over wealth.

    2010-07-01

    There has been an increasing body of knowledge with regard to hydro- and geochemical alteration processes in overburden dumps and their impact on groundwater quality in lignite mining and reclamation operations associated with post-mining landscapes in Germany. The operators of the MIBRAG mines have examined issues regarding alteration processes and how they affect the environment and which opportunities exist to actively influence the dumping process. The objectives were to counteract any possible negative impact of the alteration processes. Special emphasis was on the impact caused by oxidation of sulfur containing minerals. This paper presented an analysis of the situation at United Schleenhain Mine and how it reflects on the work to date for MIBRAG's mines. A future outlook was also presented. Specifically, the paper discussed the development of the United Schleenhain mine and the post-mining landscape. The potential for discharge of substances was also evaluated along with acidification. 1 tab., 5 figs.

    In order to obtain the best social and environmental results from mining activities, different solutions, which involve a variety of perspectives, have been proposed. These include the worldwide perspective based in the economy globalization paradigms; the regional perspective, focused in the integration of countries; the national perspective, which emphasizes the natural assets and development options, and finally a local perspective is incorporated to account for the participation of directly affected communities. Within this framework, the mining industry is requested to develop both technological and managerial tools appropriate to evaluate, optimize and communicate the social and environmental performance and output of its related activities, mainly in the developing countries. On the other hand, the governments have been committed to implement regulatory actions, of command and control type, based on an environmental legislation in line with the above mentioned perspectives and also to use economical instruments as a mean to accomplish environmental objectives. In Colombia the direct regulation methods have been traditionally used to prevent the environmental deterioration produced by mining activities, however, since the 1991 political constitution and the law 99 of 1993, the communities' participation and economical instruments were incorporated. A historic summary of the environmental legislation in our country from the early 70's up to now, showing its implications in mining is presented. Then a favorable tendency is indicated in the environmental improvement of the national extractive industry, accomplished as a result of the implementation of new strategies to minimize the impact of mining on the environment and to improve the well being of local communities

  1. Environmental licensing issues for cogeneration plants

    1990-01-01

    The siting and licensing of cogeneration and independent power production (IPP) facilities is a complex process involving a number of interrelated engineering, economic, and environmental impact considerations. Important considerations for the siting and licensing of such facilities include air quality control and air quality impacts, water supply and wastewater disposal, and applicable noise criteria and noise impact considerations. Air quality control and air quality impact considerations for power generation facilities are commonly reviewed in the public forum, and most project developers are generally aware of the key air quality licensing issues. These issues include Best Available Control Technology (BACT) demonstration requirements, and air quality modeling requirements. BACT is a case-by-case determination, which causes uncertainty, in that developers have difficulty in projecting the cost of required control systems. Continuing developments in control technology may cause this problem to continue in the 1990's. Air quality modeling can be a problem in hilly terrain or within or near an urban environment, which could delay or preclude permitting of a new cogeneration or IPP facility in such locations. This paper discusses several environmental issues which are less frequently addressed than air quality issues, namely water/wastewater and noise. The design features of typical cogeneration and IPP facilities that affect water supply requirements, wastewater volumes, and noise emissions are discussed. Then, the site selection and impact review process are examined to identify typical constraints and trade-offs that can develop relative to water, wastewater, and noise issues. Trends in permit review requirements for water, wastewater, and noise are examined. Finally, innovative approaches that can be used to resolve potential development constraints for water, wastewater, and noise issues are discussed

    In Finland, mining became popular in the mid-1990's when the mining amendments to the law made the mining activities easier for foreign companies. Also the price of the minerals rose and mining in Finland became economically profitable. Expanding mining industry brought new challenges to radiation safety aspect since radioactive substances occur in nearly all minerals. In Finnish soil and bedrock the average crystal abundance of uranium and thorium are 2.8 ppm and 10 ppm, respectively. It cannot be predicted beforehand how radionuclides behave in the mining processes which why they need to be taken into account in mining activities. Radiation and Nuclear Safety Authority (STUK) has given a national guide ST 12.1 based on the Finnish Radiation Act. The guide sets the limits for radiation doses to the public also from mining activities. In general, no measures to limit the radiation exposure are needed, if the dose from the operation liable to cause exposure to natural radiation is no greater than 0.1 mSv per year above the natural background radiation dose. If the exposure of the public may be higher than 0.1 mSv per year, the responsible party must provide STUK a plan describing the measures by which the radiation exposure is to be kept as low as is reasonably achievable. In that case the mining company responsible company has to make a radiological baseline study. The baseline study must focus on the environment that the mining activities may impact. The study describes the occurrence of natural radioactivity in the environment before any mining activities are started. The baseline study lasts usually for two to three years in natural circumstances. Based on the baseline study measurements, detailed information of the existing levels of radioactivity in the environment can be attained. Once the mining activities begin, it is important that the limits are set for the wastewater discharges to the environment and environmental surveillance in the vicinity of

    ENRESA and ENUSA have dismantled and restored a uranium mill in Andujar (Andalucia), a uranium facility based on open pit mining and plant in La Haba (Extremadura) and 19 old uranium mines in Andalucia and Extremadura. The Andujar Uranium Mill was operated from 1959 to 1981 and has been restorated between 1991 and 1994. The site included the tailings pile and the processing plant. The Haba Uranium Site included the Plant (operating from 1976 to 1999), four open-pit mines (operating from 1966 to 1990), the heaps leaching and the tailings dam and has been restorated between 1992 and 1997. The 19 abandoned uranium mines were developed by underground mining with the exception of two sites, which were operated by open pit mining. Mining operations started around 1959 and were shutdown in 1981. There was a great diversity among the mines, in terms of site conditions. Whereas in some sites there was little trace of the mining works, in other sites large excavations, mining debris piles, abandoned shafs and galeries and remaining surface structures and equipment were encountered.

    1999-05-01

    This report presents a summary of the Information Technology and Environmental Decision Making Workshop that was held at Harvard University, October 1-3, 1998. Over sixty participants from across the US took part in discussions that focused on the current practice of using information technology to support environmental decision making and on future considerations of information technology development, information policies, and data quality issues in this area. Current practice is focusing on geographic information systems and visualization tools, Internet applications, and data warehousing. In addition, numerous organizations are developing environmental enterprise systems to integrate environmental information resources. Plaguing these efforts are issues of data quality (and public trust), system design, and organizational change. In the future, much effort needs to focus on building community-based environmental decision-making systems and processes, which will be a challenge given that exactly what needs to be developed is largely unknown and that environmental decision making in this arena has been characterized by a high level of conflict. Experimentation and evaluation are needed to contribute to efficient and effective learning about how best to use information technology to improve environmental decision making.

    Full Text Available Jarosite, KFe3(SO42(OH6, is a secondary iron sulphate often found in acid mine drainage (AMD environments, particularly in mining wastes from polymetallic sulphide ore deposits. Despite the negative environmental connotation usually ascribed to secondary sulphate minerals due to the release of hazardous elements to aquifers and soils, jarosite acts as an efficient remover and immobilizer of such metals, particularly lead. The mineral chemistry of jarosite is reviewed and the results of a Fe K-edge XANES (X-Ray Absorption Near-Edge Structure study of K-, Na- and Pb-jarosite are described and discussed within the context of the abandoned old mines of São Domingos and Aljustrel located in southern Portugal, in the Iberian Pyrite Belt (IPB.

    1997-01-01

    In order to better understand the impact of acid drainage in Australia and to provide a basis for assessing long-term management options, the Office of the Supervising Scientist (OSS) and the Australian Centre for Minesite Rehabilitation Research (ACMRR) initiated this study to prepare a status report on acid mine drainage in Australia. The study is supported by the Minerals Council of Australia. The coverage of this study includes all mine sites where sulphidic oxidation in mine wastes or mine workings leads to the release of contaminated drainage with off-site impacts. The objectives of the study were: 1. to quantify and characterise the generation of contaminated drainage by sulphidic oxidation from historic and current mining activities in Australia; 2. to develop a classification scheme to characterise the potential for off-site impacts from sulphidic oxidation in mine wastes; 3. to compare the cost at the national level of managing sulphidic oxidation in mine wastes and any resulting contaminated drainage with other mining and environmental costs; 4. to make recommendations based on the information received to improve the understanding and management of acid mine drainage in Australia. Information was collected on the extent and management of sulphidic oxidation and acid drainage at operating, historic and derelict mines in Australia. Mining operators, environmental officers, industry representatives, state government departments and others were asked about their experience with acid mine drainage and how it is currently managed at operating and historic mine sites. Based on the information collected, the additional cost of managing potentially acid generating wastes at operating mine sites is estimated to be about AUD 60 million per year. Potentially, the financial risk could be much greater if sulphide oxidation and release of pollutants is discovered after mine closure, as was the case for historic sites like Mt Lyell, Rum Jungle or Mt Morgan.

    Artificial lakes, fishing spots and solar farms dot the landscape in France’s Limousin region, where uranium operations have gradually come to an end. This transformation would not have been possible without stakeholder involvement, transparent processes and well-coordinated activities, said Yves Marignac, the coordinator of the French Pluralistic Expert Group (GEP), involved with remediation activities in the region. The local population had an important consultative role during the environmental remediation programme, and they now use the former mining sites for recreation. “A consultative approach to remediation management is key to having the people’s support when we had to deal with the closing of the uranium mining sites in Limousin,” Marignac said. Uniquely, the non-governmental organizations (NGOs) were the driving force behind broadening the scope of environmental remediation, he added. An important factor for any successful remediation project is public engagement in the decision-making process. The local communities have the most interest in successful environmental remediation, and they need to get satisfactory answers to questions on why, when and how will it impact them. “Their involvement is vital and necessary to ensure technically sound and socially acceptable decisions,” Marignac said

    2017-10-01

    Mine tailings are detrimental to natural plant growth due to their physicochemical characteristics, such as high pH, high salinity, low water retention capacity, high heavy metal concentrations, and deficiencies in soil organic matter and fertility. Thus, the remediation of mine tailings has become a key issue in environmental science and engineering. Phytoremediation, an in situ cost-effective technology, is emerging as the most promising remediation method for mine tailings by introducing tolerant plant species. It is particularly effective in dealing with large-area mine tailings with shallow contamination of organic, nutrient and metal pollutants. In this review, the background, concepts and applications of phytoremediation are comprehensively discussed. Furthermore, proper amendments used to improve the physical, chemical and biological properties of mine tailings are systematically reviewed and compared. Emphasis is placed on the types and characteristics of tolerant plants and their role in phytoremediation. Moreover, the role of microorganisms and their mechanism in phytoremediation are also discussed in-depth. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The paper outlines the status of Australian coal mining industry with respect to safety and welfare of the mine employee. The impact of the longer shift hours and compressed working week are discussed in relation to workers safety and employment levels. Longer shift hours and compressed works have been shown to be a benefit to miners, both in safety and socially. The paper also examines the role of each of government organisations, the mining and manufacturing industries on the issue and goes on to describe the various environmental control measures introduced to the Australian coal mines to ensure that high safety standards are maintained. Dust monitoring and control, noise pollution control, and diesel particulate control measures have been targeted vigorously and as a result there has been a continued drop in the coal mine related diseases as well as a decline in the workers lost time injury claims. 11 refs., 7 figs., 6 tabs.

    Analyze how gender inequity manifests in contexts of poverty in different environmental risk scenarios in Mexico. Qualitative design based on six discussion groups and 54 in-depth interviews with women from six exposed communities: two to environmental manganese in a mining district, two in an industrial corridor, and two bordering a sanitary landfill. A document review of environmental and health studies in each area was done to relate them to the women's perspective on the problem. In the three case studies, by gender roles, women stay at home and do housework and, therefore, are subject to intense environmental exposure when carrying out their daily tasks, such as house cleaning. Interview and discussion group results were found to be related to epidemiological study results. In the case of the mining district, women's perceptions are consistent with study comments on adverse cognitive effects of manganese exposure. In all three cases, there are serious limitations on women's political participation in environmental risk management. Due to conditions of inequity, women are highly exposed to environmental health risks and their social participation in solving environmental problems is quite limited. These results have social and environmental policy implications in the areas studied, especially with regard to risk assessment, management, and communication.

    The concepts of exclusion, exemption and clearance have been established in international recommendations and, standards for radiation protection and the management of radioactive waste in recent years. The consistent application of these concepts has given rise to various problems in different spheres of use. This is particularly the case in the mining and minerals processing industries dealing with materials exhibiting elevated concentrations of naturally occurring radionuclides. This paper takes the South African mining industry as an example and highlights some of the issues that have arisen in applying these concepts within a regulatory control regime. (author)

    Fyrouzeh mine is located about 55 km northwest of Neyshabour in the Province of Khorasan Razavi. The exposed rocks are mainly volcanic and intrusive with intermediate composition and all of them are altered. This mine is the first type of IOCG recognized in Iran with Cu-Au-LREE-U. Besides Cu-Au-U, this area shows As, Mo, Zn and Th anomalies. Geochemical evaluation of stream sediment with regard to environmental concern revealed high Cu anomalies. Rocks show high uranium anomalies (up to 35 ppm) higher than the standard values (1 ppm). Airborne radiometric maps show high U and Th anomalies in a broad area. Ag, Hg and Mn show anomalies within the stream sediments. Cu, Pb, Zn, Ag, Ni, Mn, Sb, Hg, and U content of both drinking and agricultural water are fortunately within the range of standard, only two samples have higher As content (more than 10 ppb). High level of U-Th radiation and contamination of stream sediment with respect to Cu, Hg, Ag, Mn and agricultural water to As are important environmental issues and people health therefore they need to be study.

    Soils and mining wastes from the Mediterranean mining area placed in the Sierra Minera Mountains are highly enriched in heavy metals such as lead and zinc, but also other metals such as cadmium and arsenic. Wind erosion in this area could be considered extremely high and hazards associated to this eroded sediments seems to be high because the huge amount of metals present in this wastes. Therefore, combination of high erosion rates and high metal concentration in this mining waste, make those environmental risks can be considered high for the surrounding ecosystems, but also for public health of the nearby villages and towns. In order, to study these wind erosion processes over these mining materials, some experiments for the evaluation of the transportation of soil particles were carried out. Erosion rates in this realm is particularly important during spring months, when increased activity of the eastern winds brings intense soil dragging, with strong effects on the metals dispersion, including the massive removal of sediments.

    Energy Resource of Australia (ERA) is a public company with 68% of its shares owned by the Australian company North Limited. It is currently operating one major production centre - Ranger Mine which is 260 kilometres east of Darwin, extracting and selling uranium from the Ranger Mine in the Northern Territory to nuclear electricity utilities in Japan, South Korea, Europe and North America. The first drum of uranium oxide from Ranger was drummed in August 1981 and operations have continued since that time. ERA is also in the process of working towards obtaining approvals for the development of a second mine - Jabiluka which is located 20 kilometres north of Ranger. The leases of Ranger and Jabiluka adjoin. The Minister for the Environment has advised the Minister for Resources and Energy that there does not appear to be any environmental issue which would prevent the preferred Jabiluka proposal from proceeding. Consent for the development of ERA`s preferred option for the development of Jabiluka is being sought from the Aboriginal Traditional Owners. Ranger is currently the third largest producing uranium mine in the world producing 4,237 tonnes of U{sub 3}O{sub 8} in the year to June 1997.

    International Nuclear Information System (INIS)

    2005-05-01

    Assessment of the potential environmental impact of an in situ leach (ISL) project is the first step in the permission and licensing process. An Environmental Impact Assessment (EIA) serves as the basis for preparing an Environmental Impact Statement (EIS), which in turn identifies the potential environmental and socioeconomic impact of a proposed project and outlines measures to mitigate the impact. The EIS review process serves to inform the public about a proposed project as well as provide regulatory agencies with assurance that ISL technology will comply with environmental standards, and that project sites can be rehabilitated to pre-mining use. This publication provides a step-by-step description of project parameters that must be addressed in conducting an EIA and preparing an EIS. It also includes EIA/EIS case histories for current operations in Australia, the Czech Republic, Kazakhstan and the United States of America. The publication will be useful to companies considering development of ISL projects and to regulatory personnel who are responsible for writing environmental regulations and licensing ISL projects

    Full Text Available Environmental problems are very serious and complex to be resolved through science approach, technical and legislation solely. Hence, the inclucive and active involvement and participation of civil is wanted. Civil society is inter parties interested and sure they involved directly with every planned development project and practiced at area they. Earlier study has proven that public societal involvement in environmental issue is still low and minimum. The study conducted in Jajahan Kuala Krai, Kelantan is intended to find out how far population knowledge in study area on environmental issues and the level of involvement the in said issue. This study involved 174 respondents. The study between demographic factor with respondent knowledge in environmental issues shows that is a significant relationship between respondent income and education with value of p respectively 0.039 and 0.036. The association between demographic factor with respondent's knowledge in local environmental issue on the other hand shows that there are significant relationship between gender, age, income, education and resident period with the value of p respectively 0.045, 0.000, 0.029, 0.046 and 0.000. For demographic factor in association with environmental issues, has shown that there is a significant relationship between age, income, education and resident period with the value of p respectively 0.036, 0.041, 0.001 and 0.001. The results that found respondent income factor and education did influence on respondents knowledge level and involvement in environmental issues. As a conclusion, an actively engaged society in related environmental issues is very important due to the assurance of environmental quality that always will be protected.

  5. The environmental context of Acidithiobacillus ferrooxidans and its potential role as an ecosystem engineer in sulphidic mine waste

    Energy Technology Data Exchange (ETDEWEB)

    Ebenaa, Gustav

    2001-06-01

    Microorganisms are the causative agent of the environmental problems since they catalyse the weathering of the (sulphidic) waste. The chemical oxidation alone is not fast enough to create any severe environmental problems. Acidithiobacillus ferrooxidans is thought to be a key organism in weathering of sulphide minerals. A. ferrooxidans is affected by several more or less abiotic factors. The influence of temperature, pH and nutrient deficiency as potentially limiting factors for the activity of A. ferrooxidans has been investigated. It seems that temperature has less influence on its activity, but rather reflects the origin of the bacterial isolate. An alkaline pH seems enough to hinder growth and activity. The nutrients do not seem to be a limiting factor in the studied environment. The possible regulation of the activity of A. ferrooxidans is therefore a way to, at least partly, mitigate the environmental impact from mine waste. Waste from the mining industry is the largest waste problem in Sweden. With amounts over 600 million tonnes one could easily imagine the tremendous cost involved in the abatement. The MiMi-programme, with researchers from several relevant fields, has as its aim to evaluate present and to find alternative techniques to mitigate the environmental impact from mine waste. The understanding of A. ferrooxidans and its role as an ecosystem engineer is essential both in evaluating present techniques and even more so in finding alternative abatement techniques for sulphidic mine waste.

  6. Philippine Mining Capitalism: The Changing Terrains of Struggle in the Neoliberal Mining Regime

    Alvin A. Camba

    2016-06-01

    Full Text Available This article analyzes how the mining sector and anti-mining groups compete for mining outcomes in the Philippines. I argue that the transition to a neoliberal mineral regime has empowered the mining sector and weakened the mining groups by shifting the terrains of struggle onto the domains of state agencies and scientific networks. Since the neoliberal era, the mining sector has come up with two strategies. First, technologies of subjection elevate various public institutions to elect and select the processes aimed at making mining accountable and sensitive to the demands of local communities. However, they often refuse or lack the capacity to intervene effectively. Second, technologies of subjectivities allow a selective group of industry experts to single-handedly determine the environmental viability of mining projects. Mining consultants, specialists, and scientists chosen by mining companies determine the potential environmental damage on water bodies, air pollution, and soil erosion. Because of the mining capital’s access to economic and legal resources, anti-mining communities across the Philippines have been forced to compete on an unequal terrain for a meaningful social dialogue and mining outcomes.

    The primordial radionuclides ( 226 Ra, 232 Th and 40 K) are present in air, food, water, soils, rocks, mineral ores and building materials, are the sources of natural radiation. The sun, stars, rocks, and even our own body emits natural radiation. We live in a sea of natural radioactivity. Work activities involved in naturally occurring radioactive materials (NORM) are potential sources of radiation exposure to workers and members of publics. Iron, Chromite, Uranium, Phosphate and other ores contains higher activity of radionuclides. The iron ore is widely distributed in Bellary, Chitradurga, Tumkur and Chickmagalore districts of Karnataka state. The mining creates a number of environmental problems, that is destructions of important fauna and flora in this affected areas and also this leads various diseases like asthma, leukemia intestine, kidney and liver damage and lung cancer. The environmental γ-radiation levels were measured in this study area using environmental radiation dosimetry. The activity of radionuclides present in the ore samples were estimated by using Hyper Pure Germanium Detector (HPGe). The radon concentration in groundwater and indoor and outdoor concentration were measured by Emanometry and SSNTD techniques. The higher gamma equivalent effective doses were observed at the industrial operation and where the large quantity of iron ore and fines were dumped at the mining sites. The absorbed gamma dose to the workers in study area is slightly higher than the global average. The present work highlights the influence of mining activity, mineral processing and industrial operations are enhanced the fine sized particles, and radon in indoor and outdoor atmosphere is the sources of external radiation dose to the workers and publics.

    Global concern about the environment is increasing, and the People's Republic of China (PRC) is not immune from such concerns. The Chinese face issues similar to those of many other developing nations. The US Department of Energy is particularly interested in national and world pollution issues, especially those that may infringe on other countries' economic growth and development. The DOE is also interested in any opportunities that might exist for US technical assistance and equipment in combating environmental problems. Our studies of articles in the China Daily, and English-language daily newspaper published by the Chinese government, show that population, pollution, and energy are major concerns of the Chinese Communist Party. Thus this report emphasizes the official Chinese government view. Supporting data were also obtained from other sources. Regardless of the severity of their various environmental problems, the Chinese will only try to remedy those problems with the greatest negative effects on its developing economy. They will be looking for foreign assistance, financial and informational, to help implement solutions. With the Chinese government seeking assistance, the United States has an opportunity to export basic technical information, especially in the areas of pollution control and monitoring, oil exploration methods, oil drilling technology, water and sewage treatment procedures, hazardous waste and nuclear waste handling techniques, and nuclear power plant safety procedures. In those areas the US has expertise and extensive technical experience, and by exporting the technologies the US would benefit both economically and politically. 59 refs., 3 figs

    The study was carried out to analyse the environmental impacts of coal mine and coal-based thermal power plant to the surrounding environment of Barapukuria, Dinajpur. The analyses of coal, water, soil and fly ash were carried out using standard sample testing methods. This study found that coal mining industry and coal-based thermal power plant have brought some environmental and socio-economic challenges to the adjacent areas such as soil, water and air pollution, subsidence of agricultural land and livelihood insecurity of inhabitants. The pH values, heavy metal, organic carbon and exchangeable cations of coal water treated in the farmland soil suggest that coal mining deteriorated the surrounding water and soil quality. The SO4(2-) concentration in water samples was beyond the range of World Health Organisation standard. Some physico-chemical properties such as pH, conductivity, moisture content, bulk density, unburned carbon content, specific gravity, water holding capacity, liquid and plastic limit were investigated on coal fly ash of Barapukuria thermal power plant. Air quality data provided by the Barapukuria Coal Mining Company Limited were contradictory with the result of interview with the miners and local inhabitants. However, coal potentially contributes to the development of economy of Bangladesh but coal mining deteriorates the environment by polluting air, water and soil. In general, this study includes comprehensive baseline data for decision makers to evaluate the feasibility of coal power industry at Barapukuria and the coalmine itself.

    Freeman, A.M. III

    1996-01-01

    This paper provides an overview of the issues associated with environmental costing and the specific questions raised by the effort to measure the environmental costs of electricity. It focuses on three sets of issues. The first set is several conceptual issues in the valuation of environmental impacts in general. These issues are not unique to valuing the environmental impacts of electricity generation. However each of these issues has been highlighted in one way or another by the studies being discussed here. The second set of issues are specific to the design of studies of environmental effects of generating electricity. These issues are the selection of externalities for inclusion in the analysis, and whether and to what extent to include so called upstream and downstream impacts. The third set of issues involves policy implications of the results of the work that has been done to date. Factors considered include health effects of air emissions, damage to ecosystems, damage by CO 2 . 31 refs

  14. The changing face of oilsands mining : mobile crushing systems on the way

    Energy Technology Data Exchange (ETDEWEB)

    Cook, D.L.M.

    2007-06-15

    The mobile crushing system (MCS) is a new technology used in oil sand mining. With MCS, the crusher is moved right to the mine face where it is continuously loaded by shovel. The ore is then crushed on site and transported by a mobile conveyor for further processing. MMD Mineral Sizing (Canada) and Krupp Canada are the only 2 manufacturers that currently build MCS for the oilsands sector. Suncor, Albian Sands and Syncrude Canada are the 3 major oilsands operators currently using MCS. The benefits and challenges of MCS were presented. The use of large mobile surface mining equipment such as the MCS means that ground stability issues associated with large mobile truck and shovel mining operations will be reduced. In addition, given the current worker shortage in the mining industry, using single-stream mobile surface mining equipment means operators can reduce their labour force. However, some challenges remain. The sheer size and weight of the unit means it can deform the ground surface and sink under adverse conditions. Alternative tire and suspension concepts that may alleviate some of these stability issues are currently being researched. Other issues that may affect the performance of MCS include the oil sand density and viscosity around material flow. Syncrude Canada is considering the use of MCS technology to mitigate common oilsands-related environmental issues. It is also testing compact slurry preparation technology in which shovels will feed the oilsands directly into a MCS and then into the in-pit bitumen production system slurry equipment. The MCS unit at Suncor's mine cost $150 million. It has been running at 5,000 tonnes of ore per hour, equivalent to 15 loads of ore in the large trucks. Given the success of the unit, plans are in place for 5 more units to be in operation over the next 5 years. 4 figs.

  15. Environmental issues related to biomass: An overview

    Hughes, M.; Ranney, J.W.

    1993-01-01

    With public attention increasingly focused on environmentalism and climate change, there is enormous potential for the commercial use of biomass to accelerate. Renewable feedstocks such as biomass can provide more environmentally balanced sources of energy and other non-food products than fossil fuels. Biomass utilization is in a precarious position, however, with public attention increasingly focused on both its potential and the strength of the challenges it faces. The paper is divided into five sections. Section 2 briefly addresses economic environmental issues. The extent to which externalities are accounted for in the market price of fuels plays a significant role in determining both the ultimate size of biofuel markets and the extent of the environmental benefits of feedstock cultivation and conversion processes. Sections 3 through 4 catalogue the main hazards and benefits that are likely to arise in the large scale commercialization of biomass fuel and note where the major uncertainties lay. Environmental issues arise with the cultivation of each feedstock and with each step in the process of its conversion to fuel. Feedstocks are discussed in Section 3 in terms of three main groups; wastes, energy crops, and traditional agricultural crops. In Section 4, conversion processes are also divided into three groups, on the basis of the end energy carrier; gas, liquid, and solid and electricity. Section 5 is devoted to a conclusion and summary

    Society's preference structure regarding environmental issues is understood as the relative importance the society gives to various topics that collectively conform the environmental issues. Based on the hypothesis that this structure behavior and its definition vary with time, proposals are presented related to the concepts and a working plan allowing performing the structure's dynamic analysis. A method is described to gather information based on the systematic reading of a nation wide newspaper during a period time. A comparison is done between the resulting structure and several aspects as the environmental legislation, government plans and summits and environmental milestones

  18. Impact of occupational issues on DOE's environmental restoration program

    International Nuclear Information System (INIS)

    1992-01-01

    The U.S. Department of Energy (DOE) is in the midst of a 30-yr, multi-billion-dollar environmental restoration program for most of the facilities included in its nuclear weapons complex. Long-term planning efforts are under way to identify strategies and approaches for carrying out this extraordinarily complicated task. The DOE has already entered into interagency agreements with the U.S. Environmental Protection Agency and states for many of its environmental restoration sites. These agreements set legally enforceable deadlines for cleanup activities at these sites. In addition, DOE has made other commitments to Congress and the public regarding its environmental restoration schedule. Thousands of workers will be directly involved in environmental restoration activities at DOE sites. Cleanup activity will be carried out in environments involving potential exposure to highly toxic chemical substances and radionuclides. It is inevitable that occupational safety and health (OSH) issues will become both critical and highly visible to DOE. The OSH issues associated with cleanup activities will likely attract the attention of workers, unions, the media, regulators, and the public. This paper reviews three case studies describing OSH activities in DOE's environmental restoration program. These case studies will help alert DOE officials to ways that various OSH issues should be considered when planning environmental restoration activities. This activity is being coordinated with other DOE work to identify occupational requirements that are applicable to DOE cleanup work

  1. Acid drainage (AD) in nature and environmental impact of acid mine drainage (AMD) in Southern Tuscany

    International Nuclear Information System (INIS)

    Di Lella, Luigi Antonello; Protano, Giuseppe; Riccobono, Francesco

    2005-01-01

    Acid drainage (AD) is a natural process occurring locally at the Earth's surface. It consists in a substantial increase of acidity of surface waters as a result of chemical reactions occurring in the atmosphere (i.e. acid rain) or involving reactive phases (i.e. pyrite) present in the percolated medium. Acidic surface waters (usually pH < 4) can be produced by oxidation of sulphides (mainly pyrite and other iron sulphides) exposed to atmospheric oxygen, while human activities, such as mining, can greatly enhance this process. Acid drainage promoted by mining activities is called acid mine drainage (AMD) and is a primary source of environmental pollution and a world-wide problem in both active and abandoned mining areas. In fact, exposure of iron sulphides to oxidising conditions produces strongly acidic drainage waters rich in sulphate and a variety of heavy elements (i.e. As, Cd, Pb, Sb). Several occurrences of active acid mine drainage have been found in the Metalliferous Hills (southern Tuscany). The most important AMD phenomena were observed in the Fenice Capanne and Niccioleta mining areas

  2. On-Site Radon Detection of Mining-induced Fractures from Overlying Strata to the Surface: A Case Study of the Baoshan Coal Mine in China

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available Large-scale longwall mining of shallow coal seams may cause mining-induced fractures that can project completely through to the surface. This could lead to a series of mine safety and environmental issues, further deteriorating the already fragile ecological environment in the Western mining areas in China. Therefore, an accurate and effective understanding of the spatiotemporal evolution law of mining-induced fractures in overlying strata and its relationship to upper aquifers is critical. In this paper, the application of the geophysical-chemical properties of radon in mining engineering is explored as a potential solution to the shortcomings of existing surveying methods. A radioactive measurement method is proposed for the detection of the development of mining-induced fractures from overlying strata to the surface in the Baoshan Coal Mine (BCM. The on-site test indicated that the first weighting step is approximately 60 m, the average periodic weighting step is approximately 20 m, and the influence coverage of the advanced abutment pressure is approximately 30 m. The presented method could be used as an indirect technical support to increase the safety of coal mining by acting as a simple, fast, and reliable method of detecting mining-induced fractures in overlying strata.

  3. Geochemical Characteristics of TP3 Mine Wastes at the Elizabeth Copper Mine Superfund Site, Orange County, Vermont

    Remediation of the Elizabeth mine Superfund site in the Vermont copper belt poses challenges for balancing environmental restoration goals with issues of historic preservation while adopting cost-effective strategies for site cleanup and long-term maintenance. The waste-rock pile known as TP3, at the headwaters of Copperas Brook, is especially noteworthy in this regard because it is the worst source of surface- and ground-water contamination identified to date, while also being the area of greatest historical significance. The U.S. Geological Survey (USGS) conducted a study of the historic mine-waste piles known as TP3 at the Elizabeth mine Superfund site near South Strafford, Orange County, VT. TP3 is a 12.3-acre (49,780 m2) subarea of the Elizabeth mine site. It is a focus area for historic preservation because it encompasses an early 19th century copperas works as well as waste from late 19th- and 20th century copper mining (Kierstead, 2001). Surface runoff and seeps from TP3 form the headwaters of Copperas Brook. The stream flows down a valley onto flotation tailings from 20th century copper mining operations and enters the West Branch of the Ompompanoosuc River approximately 1 kilometer downstream from the mine site. Shallow drinking water wells down gradient from TP3 exceed drinking water standards for copper and cadmium (Hathaway and others, 2001). The Elizabeth mine was listed as a Superfund site in 2001, mainly because of impacts of acid-mine drainage on the Ompompanoosuc River.

    2005-01-01

    The Radium Hill uranium deposit, in semi-arid eastern South Australia, was discovered in 1906 and mined for radium between 1906 and 1931 and for uranium between 1954 and 1961 (production of 969,300 t of davidite ore averaging 0.12% U 3 O 8 ). Rehabilitation was limited to removal of mine facilities, sealing of underground workings and capping of selected waste repositories. In 2002, gamma-ray data, plus tailings, uncrushed and crushed waste rock, stream sediment, topsoil and vegetation samples were collected to assist in the examination of the current environmental status of the mine site. The preliminary data indicate that capping of tailings storage facilities did not ensure the long-term containment of the low-level radioactive wastes due to the erosion of sides of the impoundments. Moreover, active wind erosion of waste fines from various, physically unstable waste repositories causes increasing radiochemical (up to 0.94 μSv/h) and geochemical (Ce, La, Sc, Th, U, V, Y) impacts on local soils and sediments. However, measured radiation levels of soils and sediments are at or below Australian Radiation Protection Standards (20 mSv/a averaged over five consecutive years). Additional capping and landform design of the crushed waste and tailings repositories are required in order to minimise erosion and impacts on surrounding soils and sediments. (orig.)

    One of the world's largest uranium mining districts is located in the German states of Saxony and Thuringia. In 45 years of intense mining efforts, 220,000 metric tonnes of uranium were produced. This corresponds to approximately 13% of the world's post-war production. The legacy of this huge strategic mining operation is widespread damage to the environment and to humans. Financed by the federal budget and administered by the German Ministry of Economics (BMWi), the national WISMUT Corporation is now carrying out an internationally unique decommissioning and rehabilitation program. The aim is to reduce the threat to the environment to a minimum, to implement an ecologically difficult shutdown of underground and surface mining facilities, and to decontaminate former mining sites for suitable reuse. The results of nearly five years of rehabilitation work show that substantial progress has been achieved. Nevertheless, the project is subject to permanent crossfire in the political arena, mainly due to the wide public interest in issues focusing on the danger of radiation to the environment

  9. Using diatom assemblages and sulphur in sediments to uncover the effects of historical mining on Lake Arnoux (Quebec, Canada: A retrospective of economic benefits versus environmental debt

    Directory of Open Access Journals (Sweden)

    Paul Brian Hamilton

    2015-09-01

    Full Text Available Monitoring changes in environmental conditions is increasingly important as the Canadian economic infrastructure ramps up exploration and mining development in the more inaccessible northern regions of Canada. Governments are concurrently assessing effects from past mining activities and absorbing the economic cost to society with on-going remediation and monitoring initiatives. The abandoned Aldermac mine in northwestern Quebec, mined from 1932–1943, is an excellent case study for assessing the state of environmental and economic effects of past mining operations. A paleolimnological approach, using diatoms as environmental proxies, was used to evaluate the spatial and temporal impacts on aquatic receiving environments. Based on the inferences drawn from diatom assemblages in Lake Arnoux, prior to mining activity, lake water pH was similar to that of surrounding lakes (circumneutral to weakly acidic. After mining operations terminated, changes in pH and alkalinity in Lake Arnoux coincided with distinct increases in sediment sulphur content. Across a 30- to 40-year span (circa 1940 to 1970s a significant decline in phytoplankton flora coincided with lake acidification and increased clarity of the water column. This resulted in an increase in the benthic diatom population (>90%, replacing the planktonic diatoms. Observed shifts in environmental proxies are concurrent with one, and possibly two, reported tailings pond breaches at the abandoned mine site. Adverse effects of the abandoned Aldermac mine on nearby ecosystems, combined with pressure from local citizens and environmental groups, forced responsible accountability for site restoration led by the Quebec government. Based on the historical period of economic growth, the financial benefits of the Aldermac mine were significant and justify the current pay-it-backward costs for environmental remediation. However, it has now been documented that the pay-it-backward model is not sustainable in

    Liu, Shiliang; Li, Wenping; Wang, Qiqing

    2018-09-01

    Environmental engineering geological patterns (EEGPs) are used to express the trend and intensity of eco-geological environment caused by mining in underground coal mining areas, a complex process controlled by multiple factors. A new zoning method for EEGPs was developed based on the variable-weight theory (VWT), where the weights of factors vary with their value. The method was applied to the Yushenfu mining area, Shaanxi, China. First, the mechanism of the EEGPs caused by mining was elucidated, and four types of EEGPs were proposed. Subsequently, 13 key control factors were selected from mining conditions, lithosphere, hydrosphere, ecosphere, and climatic conditions; their thematic maps were constructed using ArcGIS software and remote-sensing technologies. Then, a stimulation-punishment variable-weight model derived from the partition of basic evaluation unit of study area, construction of partition state-variable-weight vector, and determination of variable-weight interval was built to calculate the variable weights of each factor. On this basis, a zoning mathematical model of EEGPs was established, and the zoning results were analyzed. For comparison, the traditional constant-weight theory (CWT) was also applied to divide the EEGPs. Finally, the zoning results obtained using VWT and CWT were compared. The verification of field investigation indicates that VWT is more accurate and reliable than CWT. The zoning results are consistent with the actual situations and the key of planning design for the rational development of coal resources and protection of eco-geological environment.

  16. Evaluating the effectiveness of British Columbia's environmental assessment process for first nations' participation in mining development

    International Nuclear Information System (INIS)

    Baker, Douglas C.; McLelland, James N.

    2003-01-01

    This paper applies effectiveness as a criterion to measure the participation of First Nations' participation in British Columbia's environmental assessment process. Effectiveness is reviewed as a means to measure policy implementation and an expanded framework is proposed to measure effectiveness. The framework is applied to three case studies in north-central British Columbia to measure the effectiveness of First Nations' participation in the EA process for mining development. All three cases failed to achieve procedural, substantive, and transactive efficacy and thereby failed to meet overall policy effectiveness. The policies used by the British Columbia government, including the relatively recent Environmental Assessment Act (1995), reflect a poor integration of First Nations people in the EA decision-making process with respect to mine development

  17. A procedure for NEPA assessment of selenium hazards associated with mining.

    Science.gov (United States)

    Lemly, A Dennis

    2007-02-01

    This paper gives step-by-step instructions for assessing aquatic selenium hazards associated with mining. The procedure was developed to provide the U.S. Forest Service with a proactive capability for determining the risk of selenium pollution when it reviews mine permit applications in accordance with the National Environmental Policy Act (NEPA). The procedural framework is constructed in a decision-tree format in order to guide users through the various steps, provide a logical sequence for completing individual tasks, and identify key decision points. There are five major components designed to gather information on operational parameters of the proposed mine as well as key aspects of the physical, chemical, and biological environment surrounding it--geological assessment, mine operation assessment, hydrological assessment, biological assessment, and hazard assessment. Validation tests conducted at three mines where selenium pollution has occurred confirmed that the procedure will accurately predict ecological risks. In each case, it correctly identified and quantified selenium hazard, and indicated the steps needed to reduce this hazard to an acceptable level. By utilizing the procedure, NEPA workers can be confident in their ability to understand the risk of aquatic selenium pollution and take appropriate action. Although the procedure was developed for the Forest Service it should also be useful to other federal land management agencies that conduct NEPA assessments, as well as regulatory agencies responsible for issuing coal mining permits under the authority of the Surface Mining Control and Reclamation Act (SMCRA) and associated Section 401 water quality certification under the Clean Water Act. Mining companies will also benefit from the application of this procedure because priority selenium sources can be identified in relation to specific mine operating parameters. The procedure will reveal the point(s) at which there is a need to modify operating

    Full Text Available The deterioration of environmental conditions is the major contributory factor to poor health and quality of life that hinders sustainable development in any region. Coal mining is one of the major industries that contribute to the economy of a country but it also impacts the environment. The chemical parameters of the coal, overburden, soil and sediments along with the coal mine drainage (CMD were investigated in order to understand the overall environmental impact from high sulphur coal mining at northeastern coalfield (India. It was found that the total sulphur content of the coal is noticeably high compared to the overburden (OB and soil. The volatile matter of the coal is sufficiently high against the high ash content of the soil and overburden. The water samples have a High Electrical Conductivity (EC and high Total Dissolve Solid (TDS. Lower values of pH, indicate the dissolution of minerals present in the coal as well as other minerals in the mine rejects/overburden. The chemical and nano-mineralogical composition of coal, soil and overburden samples was studied using a High Resolution-Transmission Electron Microscopy (HR-TEM, Energy Dispersive Spectroscopy (EDS, Selected-Area Diffraction (SAED, Field Emission-Scanning Electron Microscopy (FE-SEM/EDS, X-ray diffraction (XRD, Fourier Transform Infrared Spectroscopy (FTIR, Raman and Ion-Chromatographic analysis, and Mössbauer spectroscopy. From different geochemical analysis it has been found that the mine water sample from Ledo colliery has the lowest pH value of 3.30, Tirap colliery samples have the highest electrical conductivity value of 5.40 ms cm−1. Both Ledo and Tirap coals have total sulphur contents within the range 3–3.50%. The coal mine water from Tirap colliery (TW-15B has high values of Mg2+ (450 ppm, and Br− (227.17 ppm. XRD analysis revealed the presence of minerals including quartz and hematite in the coals. Mineral analysis of coal mine overburden (OB indicates

    1991-10-01

    Global concern about the environment is increasing, and the People's Republic of China (PRC) is not immune from such concerns. The Chinese face issues similar to those of many other developing nations. The US Department of Energy is particularly interested in national and world pollution issues, especially those that may infringe on other countries' economic growth and development. The DOE is also interested in any opportunities that might exist for US technical assistance and equipment in combating environmental problems. Our studies of articles in the China Daily, and English-language daily newspaper published by the Chinese government, show that population, pollution, and energy are major concerns of the Chinese Communist Party. Thus this report emphasizes the official Chinese government view. Supporting data were also obtained from other sources. Regardless of the severity of their various environmental problems, the Chinese will only try to remedy those problems with the greatest negative effects on its developing economy. They will be looking for foreign assistance, financial and informational, to help implement solutions. With the Chinese government seeking assistance, the United States has an opportunity to export basic technical information, especially in the areas of pollution control and monitoring, oil exploration methods, oil drilling technology, water and sewage treatment procedures, hazardous waste and nuclear waste handling techniques, and nuclear power plant safety procedures. In those areas the US has expertise and extensive technical experience, and by exporting the technologies the US would benefit both economically and politically. 59 refs., 3 figs.

  20. Prevention, communication and equity in environmental epidemiology: ethical issues.

    In environmental epidemiology research, decisions about when and how to intervene requires adequate ethical reflection. In fact, different kinds of issues may arise about: research methods and knowledge production; management of the results in terms of their overall assessments or for the implementation of preventive actions; reclamation intervention. In this contribution we propose to consider three topics we regard as crucial to this ethical debate: the reporting of conclusive research data; the correct application of the precautionary principle; and the environmental equity issues.

  1. Environmental sampling: Issues for the cut-off regime

    Fearey, B.L.

    1995-01-01

    The fissile material cut-off treaty (FMCT) initiative under the Conference on Disarmament mandate is envisioned to include certain aspects of environmental sampling and monitoring. One of the intents of this treaty is to bring certain non-NPT signatories (e.g., threshold states) under this treaty agreement along with the nuclear weapon states (NWSs). This paper provides a brief overview of some of the relevant issues that may be involved in the implementation and use of environmental monitoring for (1) verification of the cut-off regime declarations, (2) the detection of undeclared activities, and, (3) application in non-routine inspections. The intent is to provide backstopping information important for treaty negotiators. Specific issues addressed within this paper include signature sampling, differences in the proposed detection regime, potential signature integrators, specific examples and spoofing concerns. Many of these issues must be carefully considered and weighed in order to create a credibly verifiable inspection regime. Importantly, the cut-off treaty must enable nondiscriminatory implementation, while carefully assuring that nonproliferation treaty requirements are maintained (i.e., preventing unintentional release of critical weapons design information--potentially through environmental sampling and analysis)

  3. Climate patriots? Concern over climate change and other environmental issues in Australia.

    Science.gov (United States)

    Tranter, Bruce; Lester, Libby

    2017-08-01

    Echoing the anti-pollution and resource conservation campaigns in the United States in the early-to-mid-twentieth century, some scholars advocate mobilising support for environmental issues by harnessing the notion of environmental patriotism. Taking action to reduce the impact of global warming has also been cast as a patriotic cause. Drawing upon quantitative data from a recent national survey, we examine the link between patriotism and environmental attitudes in Australia, focussing upon climate change. We find that patriotism has a largely neutral association with concern over environmental issues, with the exception of climate change and, to a lesser extent, wildlife preservation. Expressing concern over climate change appears to be unpatriotic for some Australians. Even after controlling for political party identification and other important correlates of environmental issue concerns, patriots are less likely than others to prioritise climate change as their most urgent environmental issue and less likely to believe that climate change is actually occurring.

  4. Environmental pollutants in the mining environs of Konongo in the Ashanti Region of Ghana

    1991-01-01

    The study was made to determine whether the present practice of gold mining at Konongo had affected the quality of Konongo fauna, flora and waterbed sediment. The possible environmental pollutants in the mining environs of Konongo are CN, Zn, Pb, B, and Mn. Zn, Pb and Mn were determined by Atomic Absorption Spectrophotometer. Calorimetric procedure was adopted to determine B. CN was determined by titration with rhodamine indicator. Accumulation of pollutants in waterbed sediment, fauna and flora was in the range of 0.011 - 0.064 μgg -1 for CN; 0.188 - 1.17 μgg -1 for Zn; 0.015 - 0.122 μgg -1 for Pb; 0.101- 2.76 μgg -1 for Mn and 0.05 - 0.60μgg -1 for B. The significant differences observed with respect to the concentrations of the pollutants at different locations in the sampling area were due to the divergence of the level of pollution. It is inferred from the results that the mining environs of Konongo are not polluted to any extent by the mining processes and that if the present surveillance of the discharge of wastes was maintained, mining could continue without any adverse effect on Konongo environs.

  6. Coalbed methane produced water in China: status and environmental issues.

    Science.gov (United States)

    Meng, Yanjun; Tang, Dazhen; Xu, Hao; Li, Yong; Gao, Lijun

    2014-01-01

    As one of the unconventional natural gas family members, coalbed methane (CBM) receives great attention throughout the world. The major associated problem of CBM production is the management of produced water. In the USA, Canada, and Australia, much research has been done on the effects and management of coalbed methane produced water (CMPW). However, in China, the environmental effects of CMPW were overlooked. The quantity and the quality of CMPW both vary enormously between coal basins or stratigraphic units in China. The unit produced water volume of CBM wells in China ranges from 10 to 271,280 L/well/day, and the concentration of total dissolved solids (TDS) ranges from 691 to 93,898 mg/L. Most pH values of CMPW are more than 7.0, showing the alkaline feature, and the Na-HCO3 and Na-HCO3-Cl are typical types of CMPW in China. Treatment and utilization of CMPW in China lag far behind the USA and Australia, and CMPW is mainly managed by surface impoundments and evaporation. Currently, the core environmental issues associated with CMPW in China are that the potential environmental problems of CMPW have not been given enough attention, and relevant regulations as well as environmental impact assessment (EIA) guidelines for CMPW are still lacking. Other potential issues in China includes (1) water quality monitoring issues for CMPW with special components in special areas, (2) groundwater level decline issues associated with the dewatering process, and (3) potential environmental issues of groundwater pollution associated with hydraulic fracturing.

  7. Environmental geochemistry of acid mine drainage water at Indus coal mine at Lakhra, Sindh Pakistan

    International Nuclear Information System (INIS)

    Siddique, I.; Shah, M.T.

    2000-01-01

    The annual coal production of Pakistan is about 3,637, 825 tones which is about 6% of the country's energy resources, out of this 1,241, 965 tones of coal was produced/ mined from the Lakhra coal field, District Dadu, Sindh which after the Thar coal field is the second largest coal field of Pakistan. At this coal field more than 58 mining companies are engaged in exploring the hidden wealth of the country. The problem of acid mine drainage, is caused by the passage or seepage of water, through mines where iron disulfides, usually pyrites, are exposed to the oxidizing action of water, air and bacteria, is the main problem faced by the mining companies. The geochemical analysis of acid mine drainage water collected from Indus coal mine no. 6 shows that beside its higher pH, total Dissolved Solids and Sulfates, it also posses higher amount of heavy metals like Cd, Cu, Pb, Co, Ni and Fe. This acid mine drainage water not only damages the mine structures but is also harmful to soil and ecology. (author)

  9. Nuclear safety, environmental and community impacts of uranium mining - Canada

    International Nuclear Information System (INIS)

    Scissons, Kevin H.

    2009-01-01

    The Canadian Nuclear Safety Commission (CNSC) is mandated under the Nuclear Safety and Control Act (NSCA, the CNSC's mandate is set out in Section 9 of the Nuclear Safety and Control Act.) for regulating all nuclear facilities and nuclear-related activities in Canada. Before any person or company can prepare a site, construct, operate, decommission or abandon a nuclear facility, or possess, use, transport or store nuclear substances, they must obtain a licence issued by the CNSC. This paper provides an overview of the licensing of uranium mines and mills in Canada, taking into consideration the requirements of the NSCA and associated regulations concerning the environment, the people and the communities we protect. Describing the role of the CNSC and our regulatory framework will form a key foundation to this paper. This paper will also explain the different licensing phases and their focus for uranium mines and mills. It will conclude with an overview of our community involvement (social, public aspects) and our joint regulatory approach for defence in depth. (orig.)

    Environmental issues in the 21st century D.B. Chambers SENES Consultants Limited, Richmond Hill, Ontario, Canada Abstract. This paper provides an overview of some of the environmental challenges facing the uranium production industry in the 21st century. For many years, the linear, non-threshold (LNT) model has been regarded as a prudent hypothesis for radiation protection purposes. This paradigm has been challenged at the same time for both underestimating and overestimating the risks from ionizing radiation. The reality is that the ability of conventional epidemiology to distinguish small risks will always be limited by statistical power at low doses. In the future, there will be increased emphasis on better understanding the effects of ionizing radiation at the cellular (and sub cellular) level. The concept of 'controllable dose' has been proposed as an alternative to the International Commission on Radiological Protection's (ICRP) current approach to dose limitation. The concept is that if the most exposed individual is protected, then society as a whole is protected. A hazard ranking scale based on comparisons to natural background levels of radiation has been proposed. Adoption of a concept such as 'controllable dose' would require a parallel re-evaluation of the concepts and application of collective dose and ALARA optimization. The protection of non-human biota is an issue of considerable interest in many countries. The science in this area is rapidly evolving, as are discussions of a more philosophical nature. For example, should the focus of environmental risk assessment be the sustainability of the population or should the focus be to limit effects on a single member of the population? The future of environmental risk assessment should be of great interest to the uranium production industry. A systematic approach to risk assessment addressing the full scope of potential hazards -- environmental, human health, engineering, financial and others -- will be

  11. Application of EREP imagery to fracture-related mine safety hazards and environmental problems in mining

    The author has identified the following significant results. Numerous fracture traces were detected on both the color transparencies and black and white spectral bands. Fracture traces of value to mining hazards analysis were noted on the EREP imagery which could not be detected on either the ERTS-1 or high altitude aircraft color infrared photography. Several areas of mine subsidence occurring in the Busseron Creek area near Sullivan, Indiana were successfully identified using color photography. Skylab photography affords an increase over comparable scale ERTS-1 imagery in level of information obtained in mined lands inventory and reclamation analysis. A review of EREP color photography permitted the identification of a substantial number of non-fuel mines within the Southern Indiana test area. A new mine was detected on the EREP photography without prior data. EREP has definite value for estimating areal changes in active mines and for detecting new non-fuel mines. Gob piles and slurry ponds of several acres could be detected on the S-190B color photography when observed in association with large scale mining operations. Apparent degradation of water quality resulting from acid mine drainage and/or siltation was noted in several ponds or small lakes and appear to be related to intensive mining activity near Sullivan, Indiana.

    2002-01-01

    The Canadian Nuclear Safety Commission (CNSC) regulates uranium mining in Canada. The CNSC regulatory process requires that a licence applicant plan for and commit to future decommissioning before irrevocable decisions are made, and throughout the life of a uranium mine. These requirements include conceptual decommissioning plans and the provision of financial assurances to ensure the availability of funds for decommissioning activities. When an application for decommissioning is submitted to the CNSC, an environmental assessment is required prior to initiating the licensing process. A case study is presented for COGEMA Resources Inc. (COGEMA), who is entering the decommissioning phase with the CNSC for the Cluff Lake uranium mine. As part of the licensing process, CNSC multidisciplinary staff assesses the decommissioning plan, associated costs, and the environmental assessment. When the CNSC is satisfied that all of its requirements are met, a decommissioning licence may be issued. (author)

    Harness, J.; Atalay, A.; Koll, K.J.; Zhang, H.; Maggon, D.

    1991-12-31

    The objective of this program was to conduct an environmental impact assessment study for selenium from coal mine spoils. The use of in-situ lysimetry to predict selenium speciation, transformation, and mobility under natural conditions was evaluated. The scope of the study was to construct and test field-scale lysimeter and laboratory mini-column to assess mobility and speciation of selenium in coal mine overburden and soil systems; to conduct soil and groundwater sampling throughout the state of Oklahoma for an overall environmental impact assessment of selenium; and to conduct an in-depth literature review on the solubility, speciation, mobility, and toxicity of selenium from various sources. Groundwater and surface soil samples were also collected from each county in Oklahoma. Data collected from the lysimeter study indicated that selenium in the overburden of the abandoned mine site was mainly found in the selenite form. The amount of selenite found was too low and immobile to be of concern to the environment. The spoil had equilibrated long enough (over 50 years) that most of the soluble forms of selenium have already been lost. Examination of the overburden indicated the presence of pyrite crystals that precipitated over time. The laboratory mini-column study indicated that selenite is quite immobile and remained on the overburden material even after leaching with dilute acid. Data from groundwater samples indicated that based on the current permissible level for selenium in groundwater (0.01 mg Se/L), Oklahoma groundwater is widely contaminated with the element. However, according to the new regulation (0.05 mg Se/L), which is to be promulgated in 1992, only 9 of the 77 counties in the state exceed the limit.

    2013-07-15

    After the BP Statistical Review of World Energy of 2010 45.6% of coal production and 46.9% of coal consumption in the world in 2009 are accounted for China. The large-scale coal production and use cause major environmental impacts. A large environmental impact is through the emission of some unavoidable reaction products (for example waste gas, waste heat) that affect and damage the ecosystem. A steady influence can lead to long-term climate changes and medium term damage to the ecosystem. Other environmental impacts occur during mining of coal by the change in the water balance and the transformation of the landscape (surface mining, spoil tips). The environmental problems caused by coal mining and utilization can not be ignored in China. [German] Nach der BP-Statistik der Weltenergie 2010 sind 45,6% der Kohleproduktion und 46,9% des Kohleverbrauchs in der Welt im Jahr 2009 auf China entfallen. Die grossangelegte Kohlefoerderung und -verwendung fuehren zu grossen Umweltbelastungen. Eine grosse Umweltbeeinflussung erfolgt durch die Emission von zum Teil unvermeidbaren Umsetzungsprodukten (zum Beispiel Abgas, Abwaerme), die das Oekosystem beeinflussen und schaedigen. Eine stetige Beeinflussung kann langfristig zu den Klimaveraenderungen und mittelfristig zur Schaedigung des Oekosystems fuehren. Weitere Umweltbelastungen erfolgen beim Abbau der Kohle durch die Veraenderung des Wasserhaushalts und durch die Umgestaltung der Landschaft (Tagebau, Abbauhalden). Die Umweltprobleme, die durch die Kohlefoerderung und -nutzung verursacht werden, koennen in China nicht ignoriert werden.

  18. An Information Framework for Facilitating Cost Saving of Environmental Impacts in the Coal Mining Industry in South Africa

    Mashudu D. Mbedzi

    2018-05-01

    Full Text Available Coal-mining contributes much to the economic welfare of a country. Yet it brings along a number of challenges, notably environmental impacts which include water pollution in a water scarce country such as South Africa. This research is conducted in two phases. The first phase intends to establish environmental and other challenges brought about by the coal-mining industry through a comprehensive analysis of available literature. Combatting these challenges is costly; consequently, our work investigates how established management accounting tools and techniques such as Environmental Management Accounting (EMA, Material Flow Cost Accounting (MFCA and Life Cycle Costing (LCC may facilitate cost savings for the companies involved. These techniques promote increased transparency of material usage by tracing and quantifying the flows and inventories of materials within the coal-mining industry in physical and monetary terms, hence hidden costs are elicited. The researchers postulate that an Information Framework integrating these aspects may be the way forward. To this end existing frameworks in the literature are identified. A number of research questions embodying the above aspects are defined and the objective is to define a conceptual framework to facilitate cost savings for coal-mining companies. The main contribution of this work is an information framework presented towards the end of this article. The second phase of the research will involve fieldwork in the form of a survey among stakeholders in industry to validate the conceptual framework.

  19. Environmental impact assessment of sand mining from the small catchment rivers in the southwestern coast of India: a case study.

    2011-01-01

    In the past few decades, the demand for construction grade sand is increasing in many parts of the world due to rapid economic development and subsequent growth of building activities. This, in many of the occasions, has resulted in indiscriminate mining of sand from in-stream and floodplain areas leading to severe damages to the river basin environment. The case is rather alarming in the small catchment rivers like those draining the southwestern coast of India due to limited sand resources in their alluvial reaches. Moreover, lack of adequate information on the environmental impact of river sand mining is a major lacuna challenging regulatory efforts in many developing countries. Therefore, a scientific assessment is a pre-requisite in formulating management strategies in the sand mining-hit areas. In this context, a study has been made as a case to address the environmental impact of sand mining from the in-stream and floodplain areas of three important rivers in the southwestern coast of India namely the Chalakudy, Periyar and Muvattupuzha rivers, whose lowlands host one of the fast developing urban-cum-industrial centre, the Kochi city. The study reveals that an amount of 11.527 million ty(-1) of sand (8.764 million ty(-1) of in-stream sand and 2.763 million ty(-1) of floodplain sand) is being mined from the midland and lowland reaches of these rivers for construction of buildings and other infrastructural facilities in Kochi city and its satellite townships. Environmental Impact Assessment (EIA) carried out as a part of this investigation shows that the activities associated with mining and processing of sands have not only affected the health of the river ecosystems but also degraded its overbank areas to a large extent. Considering the degree of degradation caused by sand mining from these rivers, no mining scenario may be opted in the deeper zones of the river channels. Also, a set of suggestions are made for the overall improvement of the rivers and its

    Full Text Available Abstract: From a constitutional perspective, the responsibilities over environmental issues cannot be precisely divided between federal and state governments. Environmental problems could only be dealt with successfully, as the Malaysian case exemplify, through a concurrent jurisdiction. The responsibility for the implementation of environmental laws is left to the states which because of their nearness to the source of environmental problems are in a better position to monitor violations. However, interstate environmental problems must be addressed jointly by federal and state governments.

    Economic instruments, including environmentally related taxes, play an increasing role in the environmental policies of developed countries. This publication addresses the use of environmental taxes and their effectiveness in reducing environmental damage. It finds these taxes are a powerful tool for implementing environmental strategy. It also describes obstacles to increased use of such taxes (e.g. concerns about competitiveness and distributional effects) and suggests ways to overcome such barriers. Particular attention is given to issues and options related to taxes on greenhouse gases. 18 figs., 13 tabs.

  3. African Mining, Gender and Local Employment

    2014-12-01

    Access to employment improves women's lives and is listed among the top five priorities for promoting gender equality in the 2012 World Development Report. This paper addresses this issue by exploring women's labor market opportunities in Africa within one very important and growing sector: extractive industries. Africa's opportunities are being transformed by new discoveries of natural resources and their rising prices, and the mining sector is the main recipient of foreign direct investment in Sub-Saharan Africa. Whether the discovery of natural resources is a blessing or a curse to a country's citizens is a contentious issue, and natural resource dependence has been linked to negative outcomes at the national level such as environmental degradation, conflict, elite capture of rents and low female labor force participation. Natural resource extraction has been argued to be a hindrance to women's labor market participation by increasing reservation wages and by decreasing market demand for female labor. We perform the first cross-national study testing these hypotheses with micro-data. To do this we combine survey data on 500,000 women in Sub-Saharan Africa with geo-coded data on 900 large-scale mines (see Figure 1). We treat mine openings and mine closings as natural experiments to explore local labor market changes. Industrial mines generate local structural shifts. Subsistence farming becomes less important for both men and women. However, men shift to skilled manual labor, and women shift to service sector jobs. This contradicts the hypothesis that natural resource extraction is detrimental to women, by not providing them with new job opportunities. However, in support of the hypothesis, women decrease their labor market participation more than men do. A back-of-the-envelope calculation estimates that 90,000 women across Africa benefit from service sector jobs as a direct result of industrial mining in their communities, but 280,000 women leave the labor force

    In the mining of perlite deposits, controlling the generation of fine particles and the concentration of metals is of outstanding importance to meet the environmental and market requirements. Particle size and chemical purity are conventionally manipulated during the processing of the ore to achieve high product specifications. However, the current practices do not consider a proactive approach that focuses in the in-pit characterisation of the ore that would minimise the environmental impact...

    Noble, B.F.; Bronson, J.E.

    2005-01-01

    This paper examines the integration of human health considerations into environmental impact assessment (EIA) in the Canadian North. Emphasis is placed on the northern mining sector, where more land has been staked in the past decade than in the previous 50 years combined. Using information from interviews with northern EIA and health practitioners and reviews of selected project documents, we examined three principal mining case studies, northern Saskatchewan uranium mining operations, the Ekati diamond project, and the Voisey's Bay mine/mill project, to determine whether and how health considerations in EIA have evolved and the current nature and scope of health integration. Results suggest that despite the recognized link between environment and health and the number of high-profile megaprojects in Canada's North, human health, particularly social health, has not been given adequate treatment in northern EIA. Health considerations in EIA have typically been limited to physical health impacts triggered directly by project-induced environmental change, while social and other health determinants have been either not considered at all, or limited to those aspects of health and well-being that the project proponent directly controlled, namely employment opportunities and worker health and safety. In recent years, we have been seeing improvements in the scope of health in EIA to reflect a broader range of health determinants, including traditional land use and culture. However, there is still a need to adopt impact mitigation and enhancement measures that are sensitive to northern society, to monitor and follow up actual health impacts after project approval, and to ensure that mitigation and enhancement measures are effective.

    In the 21st century, in the fabrication of various industrial parts, particularly, current and future electronics devices in the semiconductor industry, environmental safety issues should be carefully considered. We coined a new term, environmental safety issues for semiconductors, considering our semiconductor research and technology which include environmental and ecological factors. The main object of this analysis is to address the present situation of environmental safety problems in the semiconductor industry; some of which are: (1) the generation and use of hazardous toxic gases in the crystal growth procedure such as molecular beam epitaxy (MBE) and metalorganic chemical vapor deposition (MOCVD), (2) the generation of industrial toxic wastes in the semiconductor process and (3) scarce materials recycling from wastes in the MBE and MOCVD growth procedure

    Full Text Available Mining causes severe adverse effects such as pollution and forced resettlement. Accordingly, it has prompted conflicts that are also evident in China. Our study assesses whether and how rural residents’ engage in environmental activism (EA against mining. This is achieved by constructing a model of EA strategies, coupled to variables that examine respondents’ intentions. The model uses data from a survey (n = 352 covering 37 villages spread over 5 provinces and 1 provincial-level municipality. The model is based on a refinement of the theory of planned behavior (TPB. Various findings are reported: (1 a majority of respondents (77% believes that pollution in the mining areas is serious; (2 there is pessimism about the effects of EA with 41% believing it does not improve the environment, and less than one-fifth feeling the government supports EA, contradictorily; (3 well over half has engaged in one or more forms of EA, while (4 dominant EA strategies consist of complaining to local government or village authorities (both over 40%, or open protest (opted for by over 17%; (5 economic dependency and gender affect the intention for EA, as those employed in mining and women are less inclined to participate. Whereas studies pointed to “inclined abstainers” or the “silent majority”, this study ascertains that—with regard to mining—rural residents are not silent. We posit that a threshold of environmental endurance might have been reached. In this context, policymakers need to tackle the adverse effects of mining, as it is likely to generate more violent confrontations that ultimately pose risks to political credibility and social stability.

    Mining is the extraction and processing of valuable ferro and non-ferro metals and minerals to be further used in manufacturing industries. Valuable metals and minerals are extracted from the geological deposits and ores deep in the surface through complex manufacturing technologies. The extraction and processing of mining industries involve particle emission to air or water, toxicity to the environment, contamination of water resources, ozone layer depletion and most importantly decay of human health. Despite all these negative impacts towards sustainability, mining industries are working throughout the world to facilitate the employment sector, economy and technological growth. The five most important miners in the world are South Africa, Russia, Australia, Ukraine, Guinea. The mining industries contributes to their GDP significantly. However, the most important issue is making the mining world sustainable thus reducing the emissions. To address the environmental impacts caused by the mining sectors, this paper is going to analyse the environmental impacts caused by the 5 major minerals extraction processes, which are bauxite, ilmenite, iron ore, rutile and uranium by using the life-cycle impact assessment technologies. The analysis is done here using SimaPro software version 8.4 using ReCipe, CML and Australian indicator method.

  11. Climate Change and Environmental assessments: Issues in an African Perspective

    1997-12-31

    The present report discusses the potential for integrating climate change issues into environmental assessments of development actions, with an emphasis on sub-Sahara Africa. The study is motivated by the fact that future climate change could have significant adverse impacts on the natural and socio-economic environment in Africa. Yet, to date global change issues, including climate change, have been largely overlooked in the process of improving environmental assessment procedures and methodologies. It is argued that although emissions of greenhouse gases in Africa are negligible today, it is highly relevant to include this aspect in the planning of long-term development strategies. The report discusses potential areas of conflicts and synergies between climate change and development goals. The general conclusion is that environmental assessments could be an appropriate tool for addressing climate change issues, while there are still several obstacles to its practical implementation. Four priority areas are suggested for further work: (1) Environmental accounting, (2) harmonization and standard-setting, (3) implementation, and (4) risk management. 82 refs., 5 figs., 11 tabs.

    The study was made to determine whether the present practice of gold mining at Konongo had affected the quality of Konongo fauna, flora and waterbed sediment. The possible environmental pollutants in the mining environs of Konongo are CN, Zn, Pb, B, and Mn. Zn, Pb and Mn were determined by Atomic Absorption Spectrophotometer. Calorimetric procedure was adopted to determine B. CN was determined by titration with rhodamine indicator. Accumulation of pollutants in waterbed sediment, fauna and flora was in the range of 0.011 - 0.064 Greek-Small-Letter-Mu gg{sup -1} for CN; 0.188 - 1.17 Greek-Small-Letter-Mu gg{sup -1} for Zn; 0.015 - 0.122 Greek-Small-Letter-Mu gg{sup -1} for Pb; 0.101- 2.76 Greek-Small-Letter-Mu gg{sup -1} for Mn and 0.05 - 0.60 Greek-Small-Letter-Mu gg{sup -1} for B. The significant differences observed with respect to the concentrations of the pollutants at different locations in the sampling area were due to the divergence of the level of pollution. It is inferred from the results that the mining environs of Konongo are not polluted to any extent by the mining processes and that if the present surveillance of the discharge of wastes was maintained, mining could continue without any adverse effect on Konongo environs.

    2006-12-01

    An approach to measuring environmental quality and trends in coal mining and industrial areas was attempted in this work. For this purpose, the establishment of a reference scale characterizing the status of environmental quality is proposed by developing an Environmental Quality Index (EQI). The methodology involves three main components: social research, the opinion of environmental experts, and the combination of new or existing indices. A survey of public opinion was carried out to identify the main environmental problems in the region of interest. Environmental experts carried out a survey, and the weights of specific environmental problems were obtained through a fuzzy Delphi method and pairwise comparison. The weight attributed to each environmental problem was computed, using new or existing indices (subindices) in the relevant literature. The EQI comprises a combination of the subindices with their own weights. The methodology was applied to a heavily industrialized coal basin in northwestern Macedonia, Greece. The results show that the new index may be used as a reliable tool for evaluating environmental quality in different areas. In addition, the study of EQI trends on an interannual basis can provide useful information on the efficiency of environmental policies already implemented by the responsible authorities.

  16. Description of basic mining legal principles.

    Science.gov (United States)

    Schmidt, Reinhard

    2014-01-01

    The Federal Mining Act manages access, via the system of mining concessions, to areas free for mining natural resources that do not belong to the surface property and deposits' owner. These cover especially important natural resources for the economy, including coal, ore, salt, crude oil and natural gas, and also terrestrial heat. For mining operations there exist, however, the same decrees for natural resources in the property of the surface owners, which are predominantly higher-value industrial minerals such as roofing slate, basalt, quartz sand, and clays for the fireproofing industry. In the case of mining laws, administrative procedures such as issuing mining concessions, approving operating plans, and issuing permits or licenses to explore according to water rights or the Federal Immission Control Act, those authorities and departments in whose remit the projects fall are dealt with by the Mining Authority. This means that the Mining Authority is the only state point of contact for the applicant, essentially an "all-in-one" service as it will itself instigate any further participation procedures required. The classic licensing procedure of mining is the operations plan procedure, whereby the operator submits an operating plan to the Mining Authority, which then examines it to ensure it fulfills mandatory legal safety objectives. If necessary these safety objectives can be met during licensing of the operating plans by stipulating additional requirements, Depending on the subject and validity period there are overall operating plans having the widest possible remit with comprehensive participation by the authorities and basic operating plans that form the basis for every mining works. There are also special operating plans, which owing to the dynamics of mining, resolve matters that suddenly become necessary or when the basic operating plans as originally conceived were not relevant. The closing-down operating plan is the designated tool for closing down

    The Mining and Industrial Complex of the Pocos de Caldas Plateau (CIPC) is located at Caldas, county in the southwest of Minas Gerais state. It is a plant of the Industrias Nucleares do Brazil S.A. -INB, the only installation in Brazil for the production of uranium concentrate (yellow-cake) as ammonium diuranate (Adu). The Environmental protection and control program in practice assures the environmental management plan, in operation, maintaining the Complex within technology standards required by updated environmental concepts. The mine is an open pit operation with a surface diameter of 1000 m and an actual average depth of 120 m. Some 44 x 10 6 m 3 of the overburden material were used in embankments structures to civil engineering works in the implantation of several installations in CIPC, and the other portion of the removed material was deposited in two pre-selected areas having both an upper area of about 2,0 x 10 6 m 2 . The annual average volume of waters transported to chemical treatment is about 9,0 x 10 5 m 3 . The mill, in its full operation, processes 2500 t of ore per day and the solid and liquid tailings are directed to a waste pond system where are contained approximately 2,0 x 10 6 m 3 (2,2 x 10 6 t) of solid wastes with an estimation of further 70 x 10 5 m 3 to be disposed. The upper surface of tailings pond is about 2,0 x 10 5 m 2 . Nowadays, the environmental protection and control program aims to the development of potential pollutant areas stabilization reintegrating them into their original features or adjusting them to other forms of laudable restoration.

    This thesis aims to appraise the relevance of using an hybrid top-down / bottom-up approach to evaluate mining projects in the perspective of sustainable development. With the advent of corporate social responsibility and sustainable development concepts, new social expectations have appeared towards companies that go beyond a sole requirement of profit earning capacity. If companies do not answer to these expectations, they risk to lose their social legitimacy. Traditionally associated with social, environmental, economical and political impacts and risks, mining activity is particularly concerned by these new issues. Whereas mineral resources needs have never been so high, mining companies are now expected to limit their negative effects and to take into account their different audiences' expectations in order to define, together, the terms of their social license to operate. Considering the diversity of issues, scales, actors and contexts, the challenge is real and necessitates tools to better understand issues and to structure dialogues. Based on the Uranium mines of Arlit (Niger) case study, this work shows that associating participatory approaches to structuration tools and literature propositions, appears as an efficient formula to better organize issues diversity and to build a structured dialogue between mining companies and their stakeholders. First Part aims to present the theoretical, institutional and sectorial contexts of the thesis. Second Part exposes work and results of the evaluation carried out in Niger. And, Third Part, shows the conclusions that can be derived from this work and presents a proposal for an evaluation framework, potentially applicable to other mining sites. (author)

    The sources of pollution from a proposed uranium mining and milling complex at Kvanefjeld in South Greenland have been evaluated. The environmental impact assessment was part of a pre-feasibility study. The main aims of this study have been to identify potential pollutants and critical pathways, to evaluate the environmental impact of technical alternatives, and to provide guide-lines for pre-operational environmental studies. The study has identified the open pit, waste dump and tailings impoundment as the most important sources of pollution. The mobility of non-radioactive elements was lower in the tailings than in the ore, whereas the reverse was true for the radioactive elements. The potential pollutants include: Be, F, V, Cr, Mn, Fe, Co, Ni, Zn, As, Se, Rb, Nb, Zr, Mo, Cd, Sb, REE, Hg, Pb, Th, U, Ra-226, Pb-210 and Po-210. This list was based on abundance and mobility in the ore and tailings and general toxicity of the elements. Fluorine is the most mobile of the elements in both ore and tailings. The concentration in ore and tailings may be up to 1% and in combination with its high toxicity, F can then be regarded as the most serious pollutant. (author) 34 tabs., 32 ills., 63 refs

    One of the most promising materials for low-cost thin film photovoltaic cells is copper indium selenide (CuInSe{sub 2} or CIS). As with any new material, successful commercialization of CIS photovoltaic (PV) technology will require attention to environmental issues related to the sources of raw materials, their usage, and the disposal and/or recycling of products at the end of their useful life. This paper focuses on three specific environmental issues related to CIS technology: (i) Economics of the use and re-use of materials; (ii) regulations on environmental disposal and waste handling, and (iii) logistics and economics of recycling and disposing of products by industries faced with comparable environmental issues.

  2. Sustainability of uranium mining and milling: toward quantifying resources and eco-efficiency.

    2008-04-01

    The mining of uranium has long been a controversial public issue, and a renewed debate has emerged on the potential for nuclear power to help mitigate against climate change. The central thesis of pro-nuclear advocates is the lower carbon intensity of nuclear energy compared to fossil fuels, although there remains very little detailed analysis of the true carbon costs of nuclear energy. In this paper, we compile and analyze a range of data on uranium mining and milling, including uranium resources as well as sustainability metrics such as energy and water consumption and carbon emissions with respect to uranium production-arguably the first time for modern projects. The extent of economically recoverable uranium resources is clearly linked to exploration, technology, and economics but also inextricably to environmental costs such as energy/water/chemicals consumption, greenhouse gas emissions, and social issues. Overall, the data clearly show the sensitivity of sustainability assessments to the ore grade of the uranium deposit being mined and that significant gaps remain in complete sustainability reporting and accounting. This paper is a case study of the energy, water, and carbon costs of uranium mining and milling within the context of the nuclear energy chain.

    Through the years, mining and beneficiation processes in Panasqueira Sn-W mine (Central Portugal) produced large amounts of As-rich mine wastes laid up in huge tailings and open-air impoundments (Barroca Grande and Rio tailings) that are the main source of pollution in the surrounding area once they are exposed to the weathering conditions leading to the formation of acid mine drainage (AMD) and consequently to the contamination of the surrounding environments, particularly soils. The active mine started the exploration during the nineteenth century. This study aims to look at the extension of the soil pollution due to mining activities and tailing erosion by combining data on the degree of soil contamination that allows a better understanding of the dynamics inherent to leaching, transport, and accumulation of some potential toxic elements in soil and their environmental relevance. Soil samples were collected in the surrounding soils of the mine, were digested in aqua regia, and were analyzed for 36 elements by inductively coupled plasma mass spectrometry (ICP-MS). Selected results are that (a) an association of elements like Ag, As, Bi, Cd, Cu, W, and Zn strongly correlated and controlled by the local sulfide mineralization geochemical signature was revealed; (b) the global area discloses significant concentrations of As, Bi, Cd, and W linked to the exchangeable and acid-soluble bearing phases; and (c) wind promotes the mechanical dispersion of the rejected materials, from the milled waste rocks and the mineral processing plant, with subsequent deposition on soils and waters. Arsenic- and sulfide-related heavy metals (such as Cu and Cd) are associated to the fine materials that are transported in suspension by surface waters or associated to the acidic waters, draining these sites and contaminating the local soils. Part of this fraction, especially for As, Cd, and Cu, is temporally retained in solid phases by precipitation of soluble secondary minerals (through

    Environmental deterioration is one of the major issues of today's world. It not only poses serious threats to human life, health and property at local level but also presents big challenges for the sustain ability of global environment The developing countries like Pakistan are facing much bigger problems due to their rapid urbanization and lack of resources to meet the increasing demands of urban areas. Although, the problems have global dimensions, their solution lies at the local level. This paper presents an overview of the environmental issues with special reference to Pakistan and identifies the role of various stakes holders including the national, provincial and local governments, industrial and trade community, NGO's and citizens for rehabilitation and improvement of the environment. The combination of a large population and poor resource environment means that judicious means of energy use and minimum waste systems of production as well as lifestyles must be employed for sustainable development.(author)

    Indian underground mining (UGM) transport system largely deals with different fore and back bearing work processes associated with different occupational disorders and fatigue related work stress disorders (FRWSDs). Therefore, this research study is specifically aimed to determine the fatigue related problems in general and determination of Recovery Heart Rate (Rec HR) pattern and exact cause of FRWSDs in particular. A group of twenty (N = 20) UGM operators are selected for the study. Heart rate profiles and work intensities of selected workforces have been recorded continuously during their regular mine operation and the same workforces are tested on a treadmill on surface with almost same work intensity (%Maximal Heart Rate) which was earlier observed in the mine. Recovery Heart Rate (Rec HR) in both the experiment zones is recorded. It is observed that with almost same work intensity, the recovery patterns of submaximal prolonged work in mine are different as compared to treadmill. This research study indicates that non-biomechanical muscle activity along with environmental stressors may have an influence on recovery pattern and FRWSDs.

    Full Text Available Mining activities throughout the Southern African Development Community (SADC have impacted on the health and safety of mining communities for many decades. Despite the economic contribution of mining to surrounding communities, a huge amount of social and environmental harm is associated with the industry. In this regard, mining companies have, on the one hand, contributed toward improved social development by providing jobs, paying taxes and earning foreign exchange. On the other hand, they have been linked publicly to poor labour conditions, corruption, pollution incidents, health and safety failings, as well as disrespect of human rights. The objectives of this study are to give an overview of social and natural factors relating to health disasters in selected communities in the mining environment. Regarding the findings, this paper focuses on the social and natural factors involved in the creation of health disasters. The social factors include poverty, unemployment, poor housing and infrastructure, prostitution and a high influx of unaccompanied migrant labour. Major health issues in this regard, which will be highlighted, are the extraordinary high incidence rate of HIV and STIs (sexually transmitted infections, addiction and mental illness. The environmental (natural threats to health that will be discussed in the study are harmful particles in the air and water, excessive noise and overcrowded and unhygienic living conditions. In conclusion, the paper also finds that communities need to be ‘fenced in’ in terms of health disaster management instead of being excluded. Specific recommendations to mining companies to reduce health and safety disasters will be made to conclude the paper.

    Bauxite mining is not known to most Malaysian except recently due to environmental pollution issues in Kuantan, Pahang. Potential impacts are expected to go beyond physical environment and physical illness if the situation is not controlled. Loss of economic potentials, and the presence of unpleasant red dust causing mental distress, anger and community outrage. More studies are needed to associate it with chronic physical illness. While evidences are vital for action, merely waiting for a disease to occur is a sign of failure in prevention. All responsible agencies should focus on a wider aspect of health determinants rather than merely on the occurrence of diseases to act and the need to emphasize on sustainable mining to ensure health of people is not compromised.

    The mining industry is among the top ten industries nationwide with high occupational injury and fatality rates, and mine rescue response may be considered one of the most hazardous activities in mining operations. In the aftermath of an underground mine fire, explosion or water inundation, specially equipped and trained teams have been sent underground to fight fires, rescue entrapped miners, test atmospheric conditions, investigate the causes of the disaster, or recover the dead. Special personal protective ensembles are used by the team members to improve the protection of rescuers against the hazards of mine rescue and recovery. Personal protective ensembles used by mine rescue teams consist of helmet, cap lamp, hood, gloves, protective clothing, boots, kneepads, facemask, breathing apparatus, belt, and suspenders. While improved technology such as wireless warning and communication systems, lifeline pulleys, and lighted vests have been developed for mine rescuers over the last 100 years, recent research in this area of personal protective ensembles has been minimal due to the trending of reduced exposure of rescue workers. In recent years, the exposure of mine rescue teams to hazardous situations has been changing. However, it is vital that members of the teams have the capability and proper protection to immediately respond to a wide range of hazardous situations. Currently, there are no minimum requirements, best practice documents, or nationally recognized consensus standards for protective clothing used by mine rescue teams in the United States (U.S.). The following review provides a summary of potential issues that can be addressed by rescue teams and industry to improve potential exposures to rescue team members should a disaster situation occur. However, the continued trending in the mining industry toward non-exposure to potential hazards for rescue workers should continue to be the primary goal. To assist in continuing this trend, the mining industry

    Tanzania experienced unprecedented rush for gold mining in late 1980s and early 1990s when a similar gold rush was taking place in Latin America and other developing countries because of good gold market prices. The gold rush in Tanzania was also prompted by the socioeconomic and political transformations that were taking place in the country. The liberalization of mining policy and regulations by the government allowed foreign and local private investment in mining and encouraged small-scale mining and gold trade. Because of the liberalization, thousands of local miners, mostly from rural communities, rushed to gold mining for subsistence income. The use of mercury in gold recovery became widespread in Tanzania as a result of the gold rush. From 1992/93, the Department of Geology of the University of Dar es Salaam (UDSM in collaboration with the National Environment Management Council (NEMC) initiated studies to assess the extent of mercury pollution in the country. Further studies on mercury and other heavy metal pollution were undertaken between 1993 and 1997 by UDSM, under a broader project on 'Environmental Aspects of Mining and Industrialization in Tanzania', supported by the Swedish Agency for Research Cooperation with Developing Countries SAREC (Sida/SAREC). The above studies revealed the presence of elevated mercury concentrations in gold-ore tailings and river sediment in several gold mining areas. Studies to evaluate environmental transformation, partition and bioaccumulation of mercury in different environmental matrices and the long-term impact of mercury pollution have not been done. The present research project was initiated to provide scientific database necessary to better understand the environmental behaviour and cycling of mercury in the southwest Lake Victoria goldfields. Such data are necessary in the evaluation of environmental impacts of mercury pollution and in the mitigation of adverse impacts on the ecosystems and human health

    The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) is currently scheduled to be reauthorized in 1994. The US Department of Energy (DOE) has a significant stake in CERCLA reauthorization. CERCLA, along with its implementing regulation, the National Contingency Plan (NCP), is the principal legal authority governing DOE's environmental restoration program. The manner in which CERCLA-related issues are identified, evaluated, and dispatched may have a substantial impact on DOE's ability to conduct its environmental restoration program. A number of issues that impact DOE's environmental restoration program could be addressed through CERCLA reauthorization. These issues include the need to (1) address how the National Environmental Policy Act (NEPA) should be integrated into DOE CERCLA actions, (2) facilitate the streamlining of the Superfund process at DOE sites, (3) address the conflicts between the requirements of CERCLA and the Resource Conservation and Recovery Act (RCRA) that are especially relevant to DOE, (4) examine the criteria for waiving applicable or relevant and appropriate requirements (ARARs) at DOE sites, and (5) delineate the appropriate use of institutional controls at DOE sites

    During 1991-1993, the activity levels of the bone-coal mines were investigated in Zhejiang, Hubei, Hunan, Jiangxi and Anhui Province, respectively, where the reserve of bone-coal is about 90% of our country's total reserve. The average of γ radiation dose rate level measured for bone-coal, bone-coal cinder (BCC) and bone-coal cinder brick (BCCB) in these provinces is about 500 nGy/h, 400 nGy/h and 700 nGy/h respectively, while that for fields, roads and houses made of BCCB in corresponding regions of these provinces is about 200 nGy/h, 260 nGy/h and 300 nGy/h respectively. It is shown that the environmental activity level of bone-coal mining area is about 3 times higher than the reference spots. (authors)

    Badera, Jarosław; Kocoń, Paweł

    2014-01-01

    Surface lignite mining covers large areas and usually generates social conflicts which pose one of several energy security threats to certain states. Therefore, defining the social conditions determines the success of a mining project. Two communes were chosen for a public opinion study: Kleszczów, where the Bełchatów mine is located, and Złoczew, where a lignite deposit will soon be developed. The analysis shows, as opposed to other areas in Poland that have been projected for development, that both local communities are characterised by a high level of acceptance for lignite mining. In both cases, awareness about the profits was stronger than anxiety about the investment's negative effects. However, most inhabitants could not assess the mining company's diligence concerning its responsibility for mining damages as well as the diligence of external experts assessing the environmental impacts of excavation. Most respondents also could not assess if the legal regulations of public participation in the decision process were sufficient, but the negative opinions outweighed the positive ones. From the perspective of the energy policy, dialogue-type social communication is needed for every case of a new energy-mining project. Research on local public opinion should be the first step to opening up a social debate. - Highlights: • Lignite mining can generate social conflicts, which may threaten energy security. • Examined communes are characterised by a high level of acceptance for lignite mining. • Inhabitants cannot assess if the legal regulations of mining activity are sufficient. • From the perspective of the energy policy, broader social communication is needed. • Research on the public opinion should be the first step to open up a social debate

    The assessment indicates that there do not appear to be any significant demonstrated negative environmental impacts. Moreover, the impacts of in situ mining compare favorably with those impacts expected from conventional mining techniques. Exposure to radioactive elements is less, atmospheric emissions of radioactive and nonradioactive materials are generally less and socioeconomic impacts are decreased. In fact, because of the generally small and unskilled labor forces associated with in-situ mining, development has provided much needed economic stimulus to economically depressed areas of Texas. There are still, however, several areas of unknowns and several areas of inadequate information that will need to be addressed before a complete quantification evaluation of impacts can be made. These areas include levels of radon emissions and groundwater restoration methods and impacts. Several issues mostly relating to the interaction of industry with state and Federal regulators need to be addressed

    Degroh, Kim K.; Banks, Bruce A.; Smith, Daniela C.

    1994-01-01

    Space solar power systems for use in the low Earth orbit (LEO) environment experience a variety of harsh environmental conditions. Materials used for solar power generation in LEO need to be durable to environmental threats such as atomic oxygen, ultraviolet (UV) radiation, thermal cycling, and micrometeoroid and debris impact. Another threat to LEO solar power performance is due to contamination from other spacecraft components. This paper gives an overview of these LEO environmental issues as they relate to space solar power system materials. Issues addressed include atomic oxygen erosion of organic materials, atomic oxygen undercutting of protective coatings, UV darkening of ceramics, UV embrittlement of Teflon, effects of thermal cycling on organic composites, and contamination due to silicone and organic materials. Specific examples of samples from the Long Duration Exposure Facility (LDEF) and materials returned from the first servicing mission of the Hubble Space Telescope (HST) are presented. Issues concerning ground laboratory facilities which simulate the LEO environment are discussed along with ground-to-space correlation issues.

    The Beaverlodge uranium mining and milling facilities were operated from 1952 to 1981 with about 94% of the ore extracted from the main underground mine and 6% from smaller satellite deposits. Decommissioning work occurred from 1982 to 1985 involving periods of shutdown, salvage and reclamation. Transition phase monitoring, leading to eventual delicencing commenced in July 1985. Over the last 15 years, discharge from the tailings management facility (TMF) and a fresh water stream, impacted during the operational phase by tailings spills, has improved in water quality for most parameters of concern. Loadings to the environment of three key contaminants (radium-226, total dissolved solids and uranium) have consistently been less than during the operational phase with radium-226 having the greatest variability. Outstanding environmental issues associated with the recovering drainage system formerly used for tailings disposal, are being addressed in an enhanced environmental monitoring program to commence in 2000. Changes in water chemistry and the natural re-introduction of aquatic organisms are issues of concern. In the meantime, application for release from selected satellite areas commenced in 1999. This paper reviews the issues which have arisen during the transition phase, outlines how they have and are being addressed, and provides a comparison of original and current predictions of the recovery process underway at the former Beaverlodge mine site.

    Henriksen, Lasse Folke; Seabrooke, Leonard

    2016-09-01

    An ongoing question for institutional theory is how organizing occurs transnationally, where institution building occurs in a highly ambiguous environment. This article suggests that at the core of transnational organizing is competition and coordination within professional and organizational networks over who controls issues. Transnational issues are commonly organized through professional battles over how issues are treated and what tasks are involved. These professional struggles are often more important than what organization has a formal mandate over an issue. We highlight how 'issue professionals' operate in two-level professional and organizational networks to control issues. This two-level network provides the context for action in which professionals do their institutional work. The two-level network carries information about professional incentives and also norms about how issues should be treated and governed by organizations. Using network and career sequences methods, we provide a case of transnational organizing through professionals who attempt issue control and network management on transnational environmental sustainability certification. The article questions how transnational organizing happens, and how we can best identify attempts at issue control.

    Derelict mines pose potential risks to environmental health. Several factors such as soil structure, organic matter, and nutrient content are the greatly affected qualities in mined soils. Soil microbial communities are an important element for successful reclamation because of their major role in nutrient cycling, plant establishment, geochemical transformations, and soil formation. Yet, microorganisms generally remain an undervalued asset in mined sites. The microbial diversity in derelict mine sites consists of diverse species belonging to four key phyla: Proteobacteria, Acidobacteria, Firmicutes, and Bacteroidetes. The activity of plant symbiotic microorganisms including root-colonizing rhizobacteria and ectomycorrhizal fungi of existing vegetation in the mined sites is very high since most of these microbes are extremophiles. This review outlines the importance of microorganisms to soil health and the rehabilitation of derelict mines and how microbial activity and diversity can be exploited to better plan the soil rehabilitation. Besides highlighting the major breakthroughs in the application of microorganisms for mined site reclamation, we provide a critical view on plant−microbiome interactions to improve revegetation at the mined sites. Also, the need has been emphasized for deciphering the molecular mechanisms of adaptation and resistance of rhizosphere and non-rhizosphere microbes in abandoned mine sites, understanding their role in remediation, and subsequent harnessing of their potential to pave the way in future rehabilitation strategies for mined sites. - Highlights: • Abandoned mines pose potential risks to human and environmental health. • Re-establishment of a self-sustaining vegetative cover at derelict mines is a major challenge. • Soil microbial communities are very important for successful reclamation of mined sites. • Role of microorganisms in soil function in derelict mines needs to be understood.

    Salmi, O.H.

    2008-07-01

    This dissertation analyses the problem of co-aligning corporate strategy and public policy for effective environmental governance. A case study of the mining industry in the Russian Kola Peninsula shows how institutional arrangements (including public policies) affect the environmental performance of industrial organizations. The analysis emphasizes the motivations that drive people's decisions and how they are affected by culture and formal institutions both inside and outside the domain of public policy. It bridges management and governance studies with an added focus on engineering approaches to sustainability. In substantial terms, the dissertation has a strong focus on 'complex utilization', which has been a common environmental and natural resource strategy in Russia since the 1930s. In an important respect, complex utilization both antedates and closely resembles industrial ecology that has been developed in the West. This suggests that a lack of technical knowledge was not the principal cause of the well-known environmental problems that existed in the Soviet Union. On the contrary, the potential benefits of complex utilization were not realized because Soviet political and economic institutions provided weak incentives for pollution control and efficient resource use. The central theoretical effort of this dissertation is to show how effective environmental governance is contingent upon emergent strategy and policy processes. Both corporate environmental strategy and public environmental policy depend on power relations and network building among a variety of actors in the society. The case study yields three different emergent processes: political embedding of scientific concepts, cultural contextualization of indicators, and legitimacy in stakeholder salience. The dissertation also delivers policy recommendations pertaining to the future development of the Barents Euro-Arctic region. This future depends both on the level of political

    2015-04-01

    This paper reports research about the necessity of image making for sustainable mine developments in the Republic of Korea. One of the big risks in mining activities is mining area residents opposing mine developments and operations. Analysis of the media reports on disputes between mining companies and residents can determine causes of opposing mine developments, dispute process, and influences of disputes on processes of mining projects. To do this, civil complaints from 2009 to 2012 and 24 media reports since 2000 on opposing mining activities are analyzed. And, to analyze difficulties of mining companies, the survey is conducted to target to mining companies. 57 representatives of mining companies are participated in the survey. The result of analysis cited that the major reasons of anti-mining activities are environmental degradation and reduced agricultural productivity. And specifically because of water pollution (50%), crop damages (33%), and mining dust pollution (21%), communities of mining area are against mine developments and operations. However, 25% of residents have experience of the damage caused by mining activities and the remaining 75% of residents opposing mining activities simply have anxiety about mining pollution. In the past, construction-oriented, environment-unfriendly mining projects had lasted. And while mine reclamation had been postponed in abandoned mines, mining area residents had suffered from mining pollution. So, mining area residents are highly influenced by the prejudice that mining activities are harmful to mining area communities. Current mining projects in South Korea, unlike the past mining activity, focus on minimizing environmental damage and contributing to mining area communities financially. But, in many case of disputes between mining companies and mining area residents, the both cannot reach an agreements because of the negative prejudice. Moreover, some communities categorically refuse any mining activity. On the

    From 2010 through 2013, integrated health and environmental responses addressed an unprecedented epidemic lead poisoning in Zamfara State, northern Nigeria. Artisanal gold mining caused widespread contamination resulting in the deaths of > 400 children. Socioeconomic, logistic, and security challenges required remediation and medical protocols within the context of local resources, labor practices, and cultural traditions. Our aim was to implement emergency environmental remediation to abate exposures to 17,000 lead poisoned villagers, to facilitate chelation treatment of children ≤ 5 years old, and to establish local technical capacity and lead health advocacy programs to prevent future disasters. U.S. hazardous waste removal protocols were modified to accommodate local agricultural practices. Remediation was conducted over 4 years in three phases, progressing from an emergency response by international personnel to comprehensive cleanup funded and accomplished by the Nigerian government. More than 27,000 m3 of contaminated soils and mining waste were removed from 820 residences and ore processing areas in eight villages, largely by hand labor, and disposed in constructed landfills. Excavated areas were capped with clean soils (≤ 25 mg/kg lead), decreasing soil lead concentrations by 89%, and 2,349 children received chelation treatment. Pre-chelation geometric mean blood lead levels for children ≤ 5 years old decreased from 149 μg/dL to 15 μg/dL over the 4-year remedial program. The unprecedented outbreak and response demonstrate that, given sufficient political will and modest investment, the world's most challenging environmental health crises can be addressed by adapting proven response protocols to the capabilities of host countries.

    Full Text Available Exploitation of tailing ponds sites for storing all types of waste materials creates multiple problems concerning waste disposal and the environmental impact of the waste. Tailing ponds waste may comprise e.g. flotation tailings from ore enrichment plants. Despite the fact that companies / corporations use state-of-the-art methods of extraction and processing of copper ore, and introduce modern systems of organization and production management, the area located closest to the reservoir is exposed to its negative effects. Many types of waste material are a valuable source of secondary raw materials which are suitable for use by various industries. Examples of such materials are mining waste (flotation tailings, usually neutral to the environment, whose quantities produced in the process of exploitation of minerals is sizeable. The article compares different technological methods of mining waste disposal using AHP method and their environmental impact.

    This thesis aims to appraise the relevance of using an hybrid top-down / bottom-up approach to evaluate mining projects in the perspective of sustainable development. With the advent of corporate social responsibility and sustainable development concepts, new social expectations have appeared towards companies that go beyond a sole requirement of profit earning capacity. If companies do not answer to these expectations, they risk to lose their social legitimacy. Traditionally associated with social, environmental, economical and political impacts and risks, mining activity is particularly concerned by these new issues. Whereas mineral resources needs have never been so high, mining companies are now expected to limit their negative effects and to take into account their different audiences' expectations in order to define, together, the terms of their social license to operate. Considering the diversity of issues, scales, actors and contexts, the challenge is real and necessitates tools to better understand issues and to structure dialogues. Based on the Uranium mines of Arlit (Niger) case study, this work shows that associating participatory approaches to structuration tools and literature propositions, appears as an efficient formula to better organize issues diversity and to build a structured dialogue between mining companies and their stakeholders. First Part aims to present the theoretical, institutional and sectorial contexts of the thesis. Second Part exposes work and results of the evaluation carried out in Niger. And, Third Part, shows the conclusions that can be derived from this work and presents a proposal for an evaluation framework, potentially applicable to other mining sites. (author)
