Managing Communities – Mining MNEs’ Community Risk Management Practices

DEFF Research Database (Denmark)

Taarup Esbensen, Jacob

This PhD reflects the effort to close a gap in the multinational enterprise (MNE) risk management literature on the identification and mitigation of risk arising from local communities. Small villages and towns that are situated geographically close to the MNEs’ place of operation have increasingly......-to-date information about mining MNE operations. This improved outreach has meant that mines have been closed due to conflicts with local communities and therefor a need had arisen for MNEs to implement management practices that can effectively mitigate these types of risks....... been identified as a source of risk (BSR, 2003; ICMM, 2015). The mining industry is one of the most exposed to risks from local communities, where there historically have been many conflicts between mine owners on one side and the people living close to the mine on the other (Godoy, 1985; Hoskin, 1912...

Mining industry in Republic of Macedonia

1996-01-01

Mining production has a special significance in the economy of the Republic of Macedonia. The mining comprises 6% of national earnings in the Republic of Macedonia and accounts for 16% of all people employed in industry. Mining products include coal which assures over 80% of all electrical energy as well as raw materials for metallurgy, the refractory and clay industry, decorative stones, etc. Given the conditions of the fixed economy in the former Yugoslavia, the State controlled the prices associated with mining. Following the break up of Yugoslavia and the independence of the Republic of Macedonia, a new period was entered, one dictated by a market economy and massive privatization - a period of transition. This new period was hindered by the blockades on both north and south borders and resulted in negative repercussions for mining production, especially raw materials which were intended for export. This paper intends to describe the current situation of mining production and to evaluate the realistic economic opportunities regarding the new market conditions. (author). 5 refs., 2 tabs

Guidebook on good practice in the management of uranium mining and mill operations and the preparation for their closure

International Nuclear Information System (INIS)

1998-12-01

Over the past fifty years the uranium industry has moved from a labor-intensive industry to a 'high-tech' and capital intensive industry. Organization of knowledge, manpower and material had to change to meet the demands of several stakeholders inherent to any project and to constantly adapt to technological innovations. Today, the mission of a uranium operation is not only to make a profit while selling yellow cake to electrical power stations but also to address issues regarding safety, health, environment and demands of the regulators and the public and assure the sustainability of the operations. Good mining practice begins with the proper planning and forecasting from the discovery of a deposit to decommissioning of a mine. This report describes and defines what is considered as good practice in the various activities of a mining operation and provides an overview of the management of a single operation. As technologies are progressing rapidly in the mining industry, and as this industry is transitional, this report emphasizes the importance of training employees at all levels of the organization. The statement on good practices for the various activities of a mining operation will be useful for organizations which are planning to open new mines or intend to modernize ongoing operations. Practical examples are given in the case of histories for four different countries. The objective of this publication is not to provide strict rules on the application of good practice but to give general guidelines that can be consulted and used in many different countries

This report traces the Ontario uranium mining industry from the first discovery of uranium north of Sault Ste. Marie through the uranium boom of the 1950's when Elliot Lake and Bancroft were developed, the cutbacks of the 1960s, the renewed enthusiasm in exploration and development of the 1970s to the current position when continued production for the domestic market is assured. Ontario, with developed mines and operational expertise, will be in a position to compete for export markets as they reopen. The low level of expenditures for uranium exploration and the lack of new discoveries are noted. The report also reviews and places in perspective the development of policies and regulations governing the industry and the jurisdictional relationships of the Federal and Provincial governments

Mining in British Columbia is the second largest industrial electricity consumer. This presentation highlighted methods to help the mining industry reduce their energy requirements by limiting waste and improving efficiency. The measures are aimed at optimizing energy-use and efficiency in mining and processing and identifying opportunities and methods of improving this efficiency. Energy conservation in comminution and beneficiation is a primary focus of research activities at the University of British Columbia (UBC). The objective is to reduce energy usage in metal mines by 20 per cent overall. Open pit copper, gold and molybdenum mines are being targeted. Projects underway at UBC were outlined, with particular reference to energy usage, recovery and alternative energy sources; preconcentration; reducing energy usage from comminution in sorting, high pressure grinding rolls and high speed stirred mills; Hydromet; other energy efficient technologies such as control and flotation; and carbon dioxide sequestration. Studies were conducted at various mining facilities, including mines in Sudbury, Ontario. tabs., figs.

The US uranium mining industry: 1980 and today

International Nuclear Information System (INIS)

Stover, D.E.

1991-01-01

In 1980, 16 800 tonnes of uranium were produced in the United States, making it the largest producing nation with about 40% of Western World (WOCA) production. By 1990, US production had fallen to approximately 3500 tonnes U, representing only about 10% of WOCA production. Clearly the US uranium mining industry was strongly altered by the events of the intervening years. Widespread focus on declining prices overshadowed a second important set of events. Namely, the rapidly changing regulatory and environmental atmosphere in the United States which continues adversely to affect conventional uranium mining. As a result of these events, the size and structure of the US uranium mining industry was irrevocably changed. Within this altered industry is a rapidly maturing technology that provides a more efficient and lower-cost means of uranium production, in-situ leaching (ISL). By exploiting the advantages of relatively low capital investments, shorter development times, reduced labour costs, and increased production flexibility of ISL mining, the US uranium mining industry will be a competitive component of the world's uranium supply for the 1990s.

Improved health and safety for the large mining workforce in South Africa is a priority. Risk Assessments will be mandatory following the promulgation of the new health and safety act, due out in mid 1996. There is also a strong demand for employee organizations for participation in regulating the work process, particularly in the aspects of health and safety. The concept of system safety is that safe production is achieved through four ingredients, being, competent and trained personnel working according to appropriate standard operating practices using fit-for-purpose equipment in a well-controlled environment. A deficiency in any one of these areas will lead to an increased chance of operating problems and consequently accidents. The Mine Risk processes for risk assessment and management provide a mechanism for adopting this concept in practical mining operations; they provide a framework for identifying the root cause of safety problems as a basis for defining changes which will contribute significantly towards improving safety. The Mine Risk processes are applied practively and systematically to identify hazards and evaluate the magnitude of the associated risk in a defined aspect of the mining operation using a participative team based approach. The team, whose membership consists of highly experienced personnel drawn from all relevant departments and from positions ranging from manager to operator, then determines practical controls to reduce priority risks to acceptable levels. Team building is a natural product of this process, and should lead to higher productivity levels which is also a cause for concern. By using this process, a number of objectives of all the stakeholders in the South African Mining industry are addressed. 3 tabs.

Roberto Schoproni Bichueti

2014-04-01

Full Text Available This study aims at identifying the practices of water use management and the business performance in industries in the Brazilian mineral sector. To this end, a descriptive and quantitative study was developed, using the survey method, in industries associated with the Brazilian Mining Institute – IBRAM. The water use management practices were identified based in a model addressing the following aspects: water accounting, risk assessment, direct operations, supply chain, and stakeholders engagement. The business performance was measured from a model involving the following dimensions: economic, environmental and social. Among the results, the risks assessment involved and the direct operations practices stand out, in order to reduce the amount of water used and waste discharges. The need for greater engagement of industries with the stakeholders and the supply chain, through a more integrated and collaborative management, was also evident.

Economical Recovery of By-products in the Mining Industry

The U.S. Department of Energy (DOE) Office of Industrial Technologies, Mining Industry of the Future Program, works with the mining industry to further the industry's advances toward environmental and economic goals. Two of these goals are (1) responsible emission and by-product management and (2) low-cost and efficient production (DOE 1998). DOE formed an alliance with the National Mining Association (NMA) to strengthen the basis for research projects conducted to benefit the mining industry. NMA and industry representatives actively participate in this alliance by evaluating project proposals and by recommending research project selection to DOE. Similarly, the National Research Council (NRC) has recently and independently recommended research and technology development opportunities in the mining industry (NRC 2001). The Oak Ridge National Laboratory (ORNL) and Colorado School of Mines engineers conducted one such project for DOE regarding by -product recovery from mining process residue. The results of this project include this report on mining industry process residue and waste with opportunity for by-product recovery. The U.S. mineral processing industry produces over 30,000,000 metric tons per year of process residue and waste that may contain hazardous species as well as valuable by-products. This study evaluates the copper, lead, and zinc commodity sectors which generate between 23,300,000 and 24,000,000 metric tons per year. The distribution of residual elements in process residues and wastes varies over wide ranges* because of variations in the original ore content as it is extracted from the earth's crust. In the earth's crust, the elements of interest to mining fall into two general geochemical classifications, lithophiles and chalcophiles** (Cox 1997). Groups of elements are almost always present together in a given geochemical classification, but the relative amounts of each element are unique to a particular ore body. This paper

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.

In view of the serious economic situation the future decisions are extremely difficult for some companies closely concerned with the mining industry. The required orientation of the company towards new markets and new products requires not less, but more training and rethinking in all company divisions: from business management via personnel management to plant organisation and from marketing via development to quality assurance. This is proved by practical examples. An analysis by the ''Training'' working group has produced valuable information on the actual training requirement in the North Rhine-Westphalian engineering industry. It has worked out the concrete situation of the companies closely concerned with the mining industry in North Rhine-Westphalia from the point of view of their own training requirements. It is now the task of each individual company to analyse and reflect its concrete situation against the mirror of the results and to base the specific training requirement on the company aim.

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.

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

Exclusion, exemption and clearance in the mining and minerals industry: Practical application to South African operations

International Nuclear Information System (INIS)

Wymer, D.G.

1997-01-01

Although South Africa has no primary uranium mines, a major portion of its very large mining industry involves minerals with moderately elevated levels of naturally-occurring radionuclides, typical of elevated levels found in similar mineral deposits worldwide. Evidence both locally and internationally suggests that, where radioactive elements are not concentrated or extracted, such operations cannot normally give rise to undue radiological risks. The concept of exclusion should therefore play the major role in establishing which minerals-related operations should be subject to regulatory control, but exclusion criteria, which tend to be numerical rather than descriptive, vary widely between countries - in South Africa, very little is excluded and opportunities for granting exemptions are limited. The need for exemptions and clearance would be reduced if more extensive use of the exclusion concept were made, but it is nevertheless important to have better guidance on determining appropriate numerical exemption and clearance criteria - again, there are currently wide variations between countries, one example being the surface activity clearance levels for the reuse or recycling of uranium-contaminated items. Two examples, relating to gold mining tailings disposal and recycling of contaminated scrap steel respectively, are used to illustrate the difficulties that have arisen in South Africa on the clearance of low activity materials from the mining and minerals industry. Radon is identified as requiring separate consideration, and is the one area where more specific international guidance, based on action levels for intervention, is available. The action level for workplaces recommended by the IAEA would appear to represent a common basis for exclusion and exemption with respect to radon exposures from mining and minerals operations. For public exposures, the corresponding action level for homes, although not specifically intended for dealing with radon from nearby

The mining areas have to face urban decline problem in population and aging after its closing. Many mines were shut down due to changes in industrial structure through 20 century. Central and local governments has been trying to solve urban decline of abandoned mine areas by enacting special acts or introducing support programs for decades. In the year of 1995, South Korean government also enacted "Special act on the assistance to the development of abandoned mine areas" to promote the economy of abandoned mine areas that is depressed following the decline of the coal industry and to help balanced regional development and to improve the living standard of the residents in such abandoned mine areas. Local authorities has been trying to revitalize the regional economy by attracting tourism industry under the financial support and deregulation by this special law. With this background, this study analysis 13 regeneration cases which are utilizing the industrial heritage of the abandoned area in S. Korea. Despite the importance of mining, negative images of abandon mine have been engraved due to environmental destruction. Most of abandoned mines were left without any action since its closing. Early stage of abandoned mine area regeneration, such as Sabuk, Munkyong, are focusing on adjacent land not on abandoned mine. Abandoned mines were restored its original state and theme park including hotels, casinos and other tourist facilities were developed on adjacent land. Eco-trails on some granite caves such as Jungsun were opened to the public as natural resources not industrial heritage. The industrial heritage was very restricted to making museums about history of mining industry. However, there has been a significant change in perception toward reusing industrial heritage for urban regeneration in recent years. From the viewpoint of urban regeneration, abandon mine areas and its facilities are receiving attention as important regional assets as industrial heritage to

Environmental and community issues and the mining industry

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)

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.

Santiago Yagüe

2018-01-01

Full Text Available The generation of enormous volumes of mine-tailing waste is standard practice in the mining industry. Large quantities of these tailings are also sources of kaolinite-rich materials that accumulate in slag heaps, causing significant environmental degradation and visual impacts on the landscape. The consequences of coal refuse dumped in slagheaps calls for the study of eco-innovative solutions and the assessment of waste types. Moreover, the environmental benefits of reusing large amounts of contaminated waste are also evident. Hence, the objective of this investigation is to expand current knowledge of new siliceous-aluminium minerals and their pozzolanic activity. Four raw tailing samples are characterized to determine their chemical (by ICP/MS analysis, morphological (by SEM/EDX analysis, and mineralogical (by XRD analysis compositions prior to their thermal activation that transforms the inert wastes at various temperatures into materials with cementitious properties. The results of XRD analysis following activation confirmed that the kaolinite content is fully transformed into metakaolinite. The coal refuse samples presented sufficiently reliable levels of pozzolanic activity for use as additives in industrial cements.

Full text: After many years in the economic doldrums the world's uranium industry is undergoing a renaissance. The recent rapid price increase for the product and the anticipated market shortfalls in supply of yellowcake have are responsible for this. There is now a rush of new activity: abandoned mines from a previous era are being re-examined for their potential to be re-opened; planning for exploitation of known but undeveloped uranium deposits is proceeding at a rapid pace in many countries new to uranium mining; and finally worldwide exploration activity for uranium is expanding at a great rate with more than 400 companies now claiming to be involved in the uranium mining market. All of there activities have significant implications the radiation protection profession. At every stage of the uranium production cycle, from exploration to mining and processing through to remediation there are requirements for proper radiation protection procedures and regulation. The long period of reduced activity in uranium mining has meant that few young people have been joining the industry over the past 20 years. There is now a shortage of trained and experienced radiation protection professionals associated with the mining industry that cannot be overcome overnight. The paper discusses the development of this situation and the various strategies that are being put in place around the world to improve the situation. In particular the International Atomic Energy Agency has been working with radiation protection authorities and uranium mining industry representatives from around the world to address the issue. The latest developments in this project will be described and the future plans described. (author)

Cubis AG - for the mining industry and for new markets

In Germany the research funds for the mining industry will again be cut drastically in future. Cubis must plan and use the remaining research funds in an optimum manner in conjunction with the mining industry itself and also the mining supply industry. Close cooperation and continuous coordination between the research institutes and industrial partners will continue to be necessary for this purpose. Transfer of technology between research and industrial application must take place more smoothly. It is not a question of marketing the implementation of results of individual research and development projects; on the contrary system solutions from one source are required and offered. Long-term business relationships with industrial partners, within the framework of which contract research, advice, engineering, training, etc. can be realised, are desirable. Cubis has undertaken the responsibility to make available services to the mining industry and involve itself in new markets with the released capacities. The success so far achieved by the new company shows that competence and potential to face up to the large tasks exist. Cubis is equipped to tackle the continuous challenge of technology and safety at work, but also the tasks in the raw material and environment sectors in the nineties and is the suitable partner for solution of problems.

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 Australian Government policy is to ensure that uranium mining, milling and rehabilitation is based on world best practice standards. A best practice guide for in situ recovery (ISR) uranium mining has been developed to communicate the Australian Government's expectations with a view to achieving greater certainty that ISR mining projects meet Australian Government policy and consistency in the assessment of ISR mine proposals within multiple government regulatory processes. The guide focuses on the main perceived risks; impacts on groundwaters, disposal of mining residues, and radiation protection. World best practice does not amount to a universal template for ISR mining because the characteristics of individual ore bodies determine the best practice. (author)

Environmental pollution and its solicitation in ecological problems of old industrial and mining areas have become a worldwide technological puzzle restricting sustainable economic and social development. But, the definition and category of old industrial and mining areas is still disputed as an important concept. In this paper, the concept of old industrial and mining area was discussed in theory, and, proceeded with analyzing the complexity of current situation and environmental pollution problems of old industrial and mining areas in China, more keystone attention was paid to the secondary pollution problems from old industrial and mining areas as an important frontier of science. On the basis of expounding the complexity and characters of environmental pollution in old industrial and mining areas, it was suggested that as two key scientific problems in environmental sciences and ecology, the formation mechanisms and control technology of secondary pollution in old industrial and mining areas and the responses of new-type diseases to environmental pollution based on molecular ecotoxicology should be systematically studied on the national scale, and be an important component of environmental protection strategy in China in the future.

The industrial panopticon: mining and the medical construction of migrant African labour in South Africa, 1900-1950.

1996-01-01

Derived from a marxist/liberal humanist view of power, conventional critiques of the South African gold mining industry's medical apparatus see only its power to repress and negate the true bodily attributes and authentic person of the African mine worker. In so doing, they ignore the productive capacity of medical practice as a manifestation of what Foucault termed "disciplinary" power, by which the human body is manufactured and made manageable as an object of medical knowledge and industrial utilization. Accordingly, this paper offers just such a Foucaultian reading of South African mining medicine to demonstrate how it has operated to fabricate the bodies of African miners as visible objects possessed of distinct attributes that provoked particular strategies for their surveillance in health and disease.

Public consent for mining: An industry viewpoint

International Nuclear Information System (INIS)

Zelms, J.L.

1990-01-01

The predominance of the mining industry was never intentionally destructive to the environment. Even when laws and regulations were far more relaxed than they are today, our operations were conducted professionally, But when change came, mining companies took a noncooperative attitude. We knew that we were the mining experts and that regulators or lawmakers were not. And it became accepted in our industry to stonewall change -- not to work with regulators and lawmakers but to resist change. This same attitude spilled over into attitudes with the media. Reporters were percieved as the enemy and many felt the press misrepresented their views. So we didn't work with the media unless we absolutely had to. In the process, industry did not participate in establishing guidelines and criteria for environmental regulation. Business ceded the environmental agenda to others and we have ended up with laws that forced billions of dollars of expenditures without ensuring that those expenditures had maximum impact on environmental problems. New rules are written by people less knowledgeable about the industry, consequently they cost more than they should and may not even have the desired result. Companies end up spending more than if they had addressed the problem themselves originally. It is no longer enough merely to be mining professionals. Today, it's only a threshold requirement for enduring success. We will best earn public consent to operate by anticipating what society will expect of us and by working to meet those expectations. We must set our own public policy before they become law or regulation and before we are branded as nonresponsive and noncaring

The role of public consultation in leading practice uranium mining

Vance, R.

2014-01-01

As the raw material used to fuel nuclear power plants to generate significant amounts of electricity with life cycle carbon emissions as low as renewable energy sources, uranium is a valuable energy commodity. Yet the mining of uranium remains controversial, principally because of the environmental and health impacts created in the early years of the industry when uranium mining was conducted by governments to meet military requirements during the Cold War. At the time, maximising production in the face of rapidly rising demand was the principal goal and little concern was given to properly managing environmental and health impacts or community relations. Uranium mining is now conducted under significantly different circumstances than those in the early era of production for military purposes. Since then, 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. Leading practice uranium mining is now the most regulated and arguably one of the safest forms of mining in the world. Public consultation was seldom, if ever, undertaken in the early stages of uranium mining. As with other forms of mining, societal attitudes about health and safety and environmental protection have been accompanied by an expectation that public participation should be an integral part of planning and approval processes for uranium mines along with transparency and assurances of performance throughout the entire life cycle of the facility. Leading practice uranium mining includes repeated opportunities for public consultation throughout the life of a mining facility. Major milestones for public consultation in the mine life cycle include the environmental impact assessment process that engages the interested public and special interest groups, such as local native and aboriginal populations. In order to demonstrate that

Uranium mining industry: the challenges and opportunities

In the global power generation nuclear industry plays a vital role in this modern era which is wholly energy driven. While the demand for nuclear power generation has been growing worldwide, concerns about supply of critical nuclear equipment is one of the key areas which supports the growth of the nuclear industry. As the reemergence of nuclear industry in the global energy arena indicates a significant growth of nuclear power, forecasting the demand for various critical equipment components is critical to industry's growth together with the supply of enriched/processed uranium and related services. India is stepping in this industry in a big way and with Indo-US Nuclear deal, it is going to be a world player in its own right. The basic raw material for nuclear energy is the uranium which has the potential to be highly dangerous substance when not treated in the proper manner, remaining radioactive for hundreds and thousand of years. Uranium mining could permanently damage the environment for tens of thousand of years, if not properly mined and managed

The application of the ''linear principles as optimisation basis for the technical planning of the sedimentation tanks in the clay mining industry'' described in GLUeCKAUF 143 (2007), No. 10 permits rapid and simplified planning of the settling tanks required for this purpose, which is fully dependent on the size of the dirty water pump used. The geometrical tank size is specified in advance. The course of the sedimentation process can be clearly improved, if there is more than one settling tank in operation, whereby selection of the method of operation of the tanks can basically be left to the mine operator. Nevertheless practical experience in this field has proved that connection of the tanks in series can be regarded as more effective for the sedimentation process. (orig.)

Development and implementation of the Good Neighbor Agreement (GNA) practice in the USA sustainable mining development.

Science.gov (United States)

Masaitis, Alexandra

2014-05-01

New economic, environmental and social challenges for the mining industry in the USA show the need to implement "responsible" mining practices that include improved community involvement. Conflicts which occur in the US territory and with US mining companies around the world 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. The GNA project being currently developed at the University of Nevada, USA in cooperation with the Newmont Mining Corporation has a goal of creating an open company/community dialog that will help identify and address sociological and environmental concerns associated with mining. Discussion: The Good Neighbor Agreement currently evolving will address the following: 1. Identify spheres of possible cooperation between mining companies, government organizations, and NGO's. 2. Provide an economically viable mechanism for developing a partnership between mining operations and the local communities that will increase mining industry's accountability and provide higher levels of confidence for the community that a mine is operated in a safe and sustainable manner. Implementation of the GNA can help identify and evaluate conflict criteria in mining/community relationships; determine the status of concerns; determine the role and responsibilities of stakeholders; analyze problem resolution feasibility; maintain the community

The method used to optimize the design and operation of mine ventilation has generally been based on case studies and expert knowledge. It has yet to benefit from optimization techniques used and proven in other fields of engineering. Currently, optimization of mine ventilation systems is a manual based decision process performed by an experienced mine ventilation specialist assisted by commercial ventilation distribution solvers. These analysis tools are widely used in the mining industry to evaluate the practical and economic viability of alternative ventilation system configurations. The scenario which is usually selected is the one that reports the lowest energy consumption while delivering the required airflow distribution. Since most commercial solvers do not have an integrated optimization algorithm network, the process of generating a series of potential ventilation solutions using the conventional iterative design strategy can be time consuming. For that reason, a genetic algorithm (GA) optimization routine was developed in combination with a ventilation solver to determine the potential optimal solutions of a primary mine ventilation system based on a free splitting network. The optimization method was used in a small size mine ventilation network. The technique was shown to have the capacity to generate good feasible solutions and improve upon the manual results obtained by mine ventilation specialists. 9 refs., 7 tabs., 3 figs.

Zhou, C; Damiano, N; Whisner, B; Reyes, M

2017-12-01

The Industrial Internet of Things (IIoT), a concept that combines sensor networks and control systems, has been employed in several industries to improve productivity and safety. U.S. National Institute for Occupational Safety and Health (NIOSH) researchers are investigating IIoT applications to identify the challenges of and potential solutions for transferring IIoT from other industries to the mining industry. Specifically, NIOSH has reviewed existing sensors and communications network systems used in U.S. underground coal mines to determine whether they are capable of supporting IIoT systems. The results show that about 40 percent of the installed post-accident communication systems as of 2014 require minimal or no modification to support IIoT applications. NIOSH researchers also developed an IIoT monitoring and control prototype system using low-cost microcontroller Wi-Fi boards to detect a door opening on a refuge alternative, activate fans located inside the Pittsburgh Experimental Mine and actuate an alarm beacon on the surface. The results of this feasibility study can be used to explore IIoT applications in underground coal mines based on existing communication and tracking infrastructure.

Public Consultation Processes in Greenland Regarding the Mining Industry

Directory of Open Access Journals (Sweden)

Maria Ackrén

2016-05-01

Full Text Available Since the Greenland Self-Government Act came into force in 2009, economic development and the right to utilize natural resources in Greenland lies in the hands of the Self-Government. Earlier efforts to establish this authority were made back in the 1970s, when discussions on Home Rule were first on the agenda. Mining industries are not a new activity in Greenland. During the Second World War, Greenlandic cryolite was used to produce aluminum for the North American aircraft industry. Other essential natural resources, such as gold and gemstones, have also received international interest over the years. Greenland's new development aim is to build up a large-scale mining industry. This article elucidates the form of public consultation processes followed in Greenland in connection with two large-scale mining projects and the different views various actors have regarding these events. How did the deliberative democratic process unfold in Greenland regarding these projects? Was the process followed an effective way to manage these kinds of projects? The article shows that two projects that received a lot of media attention: the 2005 iron ore mine project in Isukasia, and the 2001 TANBREEZ-project to extract rare earth elements, used highly different approaches when it comes to deliberative democracy. In the former case, a limited degree of deliberative democracy was used, while in the latter case, the opposite applies.

Use of advanced technology in the mining activities are polluting the natural environment, interfering with the normal life of the miners/residents. In this paper, health hazards due to underground workings and effect of environmental conditions on men are discussed. A composite system inter-relationship of the mining industries with the Government, society and environmental sectors is established. Allowing certain level of pollution, a system dynamics model is developed considering the parameters like more revenues from the mining industries, degradation of quality of life index - environmental index on long-term and short-term basis, new diseases due to pollution, social awareness, health care facilities, tax exemption etc. This model will help us to understand the optimisation of the parameters to establish the better interaction in the environment-human systems in the mining industries. 14 refs., 4 figs., 2 tabs

Alexandra Masaitis, UNR NV, USA. PhD Grad St. Principles of Adoption of the Successful Environmental Policies and Practices Used in Developed Countries into the Russian Mining Industry

Science.gov (United States)

Masaitis, A.

2012-12-01

The successful implementation of the environmental policies in the mining industry is of a paramount importance, as it not only prevents both local and trans-border pollution but also guarantees a clean and healthy environment for the people regardless of their place of habitation. It is especially important to encourage the progress of the environmental policy implementation in less regulated countries such as the Russia because such countries have resource-oriented economy based on development of nonrenewable resources. Poor environmental practices in such 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 Russian mining sector ecological policies and (2) to suggest substitute policies from developed countries that could be adapted to the Russian 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 policies; 2. The comparative method of inquiry, 3. Quantitative data analysis, where data was collected from "The collection of statistic data", the US EPA open reports, and the USGS Reports; 4. Review of the Norilsk Nickel Company annual reports. The following results were obtained: Identified the systemic crisis of the ecological environmental policies in the Russian mining sector based on the development of nonrenewable resources, in the 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 assessment, and in the presence of the audit and monitoring that do not address the local conditions. Based on the above, the following concepts were thought of to improve the environmental conditions in the Russian mining sector: 1. Was developed the Regional

Nuclear regulation of South African mines: An industry perspective

International Nuclear Information System (INIS)

Wymer, D.G.

2001-01-01

South African mines have become subject to a rigid and prescriptive system of nuclear regulation that has its roots in the past when South Africa embarked upon a period of nuclear development spanning the full nuclear fuel cycle, and in which the South African gold mining industry once played a major part in the supply of uranium as a low grade by-product. Radiation hazards in the mines are generally very moderate, even in the few gold mines associated with uranium by-product, and to not warrant the type of regulatory attention normally applied to nuclear installations, or even to uranium mines. The continued imposition of strict nuclear regulatory requirements has caused severe financial hardship and threatens the survival of certain mining operations, while seemingly having little or no health benefits to workers or the public. With the development of modern, comprehensive mine health and safety legislation, a more appropriate, effective, and far less costly vehicle for controlling radiation hazards in mines now exists, utilizing the resources of the Mine Health and Safety Inspectorate. This approach is now being proposed, in the drafting of new legislation, as constituting a better alternative to the nuclear regulation of mines. (author)

Operational Decision Support for Material Management in Continuous Mining Systems: From Simulation Concept to Practical Full-Scale Implementations

Directory of Open Access Journals (Sweden)

Masoud Soleymani Shishvan

2017-07-01

Full Text Available Material management in opencast mines is concerned with planning, organizing, and control of the flow of materials from their extraction points to destinations. It can be strongly affected by operational decisions that have to be made during the production process. To date, little research has focused on the application of simulation modeling as a powerful supportive tool for decision making in such systems. Practical experiences from implementing a simulation model of a mine for the operational support on an industrial scale are not known to the authors. This paper presents the extension of a developed stochastic simulation model by the authors from a conceptual stage (TRL4 to a new Technology Readiness Level (TRL 6 by implementing it in an industrially relevant environment. A framework for modeling, simulation, and validation of the simulation model applied to two large opencast lignite mines is presented in detail. Operational implementation issues, experiences, and challenges in practical applications are discussed. Furthermore, the strength of applying the simulation modeling as an operational decision support for material management in coal mining is demonstrated. Results of the case studies are used to describe the details of the framework, and to illustrate the strength and limitations of its application.

A new productivity index to measure economic sustainability of the mining industry

International Nuclear Information System (INIS)

Rodriguez, Xose A

2010-01-01

This document aims to introduce a total productivity index to measure the economic sustainability of the mining industry. This index will take into account any technical developments, means of use of productive factors (i.e. inefficiencies and scale effects) and the effects on the growth of the geological properties in the resources to be exploited (particularly the effects of resource reduction or reserves depletion). This new index will then be applied to the example of the Spanish mining industry, with some interesting findings regarding the configuration of sustainable mining policies.

Exploring the challenges associated with the greening of supply chains in the South African manganese and phosphate mining industry

Directory of Open Access Journals (Sweden)

R.I. David Pooe

2014-11-01

Full Text Available As with most mining activities, the mining of manganese and phosphate has serious consequences for the environment. Despite a largely adequate and progressive framework for environmental governance developed since 1994, few mines have integrated systems into their supply chain processes to minimise environmental risks and ensure the achievement of acceptable standards. Indeed, few mines have been able to implement green supply chain management (GrSCM. The purpose of this article was to explore challenges related to the implementation of GrSCM and to provide insight into how GrSCM can be implemented in the South African manganese and phosphate industry. This article reported findings of a qualitative study involving interviews with 12 participants from the manganese and phosphate industry in South Africa. Purposive sampling techniques were used. Emerging from the study were six themes, all of which were identified as key challenges in the implementation of GrSCM in the manganese and phosphate mining industry. From the findings, these challenges include the operationalisation of environmental issues, lack of collaboration and knowledge sharing, proper application of monitoring and control systems,lack of clear policy and legislative direction, the cost of implementing GrSCM practices, and the need for strong leadership and management of change. On the basis of the literature reviewed and empirical findings, conclusions were drawn and policy and management recommendations were accordingly made.

Determination of possible radiation hazards associated with tin mining industry in West Malaysia

International Nuclear Information System (INIS)

Hu, S.J.

1979-04-01

A study was made in Malaysia under an IAEA research contract on the possible radiation hazards associated with tin mining industry in Malaysia. The study comprised of the measurement of external radiation levels in various mines, gamma-ray spectrometric analysis of various samples from mines, and measurements of radon and radon daughters concentrations. For radon daughters modified Tsivoglou and Kusnetz methods were used. The study showed that there is, in general, no radiation hazard associated with the tin mining industry in West Malaysia. However, the only likely source that might pose some external radiation hazard is the amang upgrading plant which invariably concentrates either or both 232 Th and 238 U in the final products of the upgrading process. A quantitative and thorough investigation of radiation levels in the amang upgrading industry is necessary to determine the degree of hazard. No significant radon or radon daughters concentrations were noted in the underground mines

Options report for the mining, non-ferrous metal smelting and refining industry

International Nuclear Information System (INIS)

1999-10-01

This plant level analysis involved the study of three Canadian mines from ore extraction to refining. Energy consumption and GHG emissions from each facility were examined, along with projects to reduce these emissions. Results showed variation in emissions between firms by orders of magnitude, and while GHG reducing projects do exist, many are not implemented for economic and business reasons. Nevertheless, a modelling analysis of the mining industry as a whole showed that the industry should be able to reduce its GH emissions to within range of the Kyoto target. Enhanced voluntary initiatives, already supported by the industry, are seen as the most cost effective means of achieving these emission reductions. Industry experts suggest more effort to be expended on identifying GHG reducing technologies and competing projects with higher returns on investment. There is incontrovertible evidence that energy efficiency measures are often not implemented by the industry because their return on investment are not as attractive as those associated with process improvement projects. With appropriate assistance from government, such as funding for comprehensive energy audits similar to the plant level analysis done for this report, funding for carrying out the detailed economic evaluation of these projects, help with specialized human resources to participate in enhanced voluntary activities (such as the energy audits and life cycle cost/benefit analysis), and financial incentives to create more attractive returns on investment for energy efficiency/GHG emission reduction projects, the Canadian mining industry will be, and can be, part of the solution towards reducing GHG emissions. Other avenues that could be helpful in this effort include exporting Canadian mining technology to aid in reaching a global solution to a global problem, recognition for the Canadian mining industry for its northern operations, credit for Canada for embodied energy in exports, and recycling to

Metallurgical engineering and inspection practices in the chemical process industries

International Nuclear Information System (INIS)

Moller, G.E.

1987-01-01

The process industries, in particular the petroleum refining industry, adopted materials engineering and inspection (ME and I) practices years ago and regularly updated them because they were faced with the handling and refining of flammable, toxic, and corrosive feed stocks. These industries have a number of nonproprietary techniques and procedures, some of which may be applicable in the nuclear power generation field. Some specific inspection and engineering techniques used by the process industries within the framework of the guidelines for inspections and worthy of detailed description include the following: (1) sentry drilling or safety drilling of piping subject to relatively uniform corrosion, such as feedwater heater piping, steam piping, and extraction steam piping; (2) on-stream radiography for thickness measurement and detection of unusual conditions - damaged equipment such as valve blockage; (3) critical analysis of the chemical and refining processes for the relative probability of corrosion; (4) communication of valuable experience within the industry; (5) on-stream ultrasonic thickness testing; and (6) on-stream and off-stream crack and flaw detection. The author, trained in the petroleum refining industry but versed in electric utilities, pulp and paper, chemical process, marine, mining, water handling, waste treatment, and geothermal processes, discusses individual practices of these various industries in the paper

Financial planning and analysis techniques of mining firms: a note on Canadian practice

Blanco, H.; Zanibbi, L.R. (Laurentian University, Sudbury, ON (Canada). School of Commerce and Administration)

1992-06-01

This paper reports on the results of a survey of the financial planning and analysis techniques in use in the mining industry in Canada. The study was undertaken to determine the current status of these practices within mining firms in Canada and to investigate the extent to which the techniques are grouped together within individual firms. In addition, tests were performed on the relationship between these groups of techniques and both organizational size and price volatility of end product. The results show that a few techniques are widely utilized in this industry but that the techniques used most frequently are not as sophisticated as reported in previous, more broadly based surveys. The results also show that firms tend to use 'bundles' of techniques and that the relative use of some of these groups of techniques is weakly associated with both organizational size and type of end product. 19 refs., 7 tabs.

The future of European mining: What should our mining industry learn from the Skouries and Rosia Montana community gold conflicts

Hardy, Liam; Heller, Shaun; Faltyn, Rowan; Stefanaki, Anna; Economidou, Romina; Savin, Irina; Hood, Leo; Conway, Christopher

2017-04-01

The popular image of mining portrayed by media and by a majority of public opinion is a dominantly negative one. From worker's rights to environmental damages, disasters such as the Copiapó mine collapse (Chile), the acid mine drainage at Lousal (Portugal) and the Pb contamination of waters around the Tyndrum mines (Scotland) overshadow initiatives like the ICMM. Some companies receive little praise despite creating active community education and investment projects, while others simply build higher barbed wire fences and attempt to weather the protests, budgeting them into mine life assessments. This image problem, combined with the decentralised political segregation of Europe and the increased power of grass-roots protest initiatives (such as Antigold in Greece), has resulted in mining companies joining a long list of industries effected by the 'auto-protest' reaction in face of development, regardless of potential regional and national benefits, there is a pre-existing lack of trust in corporate and government powers to protect community interests. The poor management of existing licences is thus becoming a significant danger to future operations and the wider industry. Here we report on the Rosia Montana dispute (Romania) and the ongoing Skouries conflict (Greece). We then discuss how the European mining industry may need to significantly adapt its exploration and community engagement strategies to avoid future conflicts and, present a recent example of how effective suitably organised community engagement projects can be for local mining initiatives from Southern Portugal.

Shpyth, A.

1997-01-01

The modern uranium mining industry in Saskatchewan has been working with northerners, governments, and educational institutions for nearly 20 years to bring about one of the highest levels of northern and aboriginal participation in an industrial sector in Canada. It has accomplished this in the face of challenges - those arising from the demographics of the north, continuously rising expectations, and the at times difficult demands from evolving aboriginal political institutions. Every second apprenticeship vacancy at Key Lake is to be awarded to an employee of aboriginal ancestry. Saskatchewan dominates uranium mining because of the high grade of its deposits. Even though Key Lake, Rabbit Lake and Cluff Lake are coming near the end of their lives, they will be replaced by: McArthur River (with average grade 15% U 3 O 8 ), Cigar Lake (9%), McClean Lake (3.5), Midwest (4.5). Without doubt, the grade and size of these new deposits will contribute to the competitiveness of the Saskatchewan uranium mining industry; but so too will the workforce

After about 20 years at a low level of activity the global uranium mining industry has been enjoying a significant expansion since about 2003. However, it is apparent that the “quiet” period has led to a shortage of new staff coming into the industry, many middle ranking and skilled professionals have moved to other industries and many of the remaining staff is fast approaching retirement. Many organizations are looking at ways to address this situation as quickly and effectively as possible, including governments, industry and the IAEA. This paper describes one training programme that has been developed, and is currently being implemented, as a joint venture between the uranium mining company AREVA NC and the Centre for Advanced Studies of Mineral Resources, which is located at the School of Mines in Ales, France.

R&D status and the performance of domestic firms in China's coal mining industry

International Nuclear Information System (INIS)

Sun, Sizhong; Anwar, Sajid

2015-01-01

Coal use accounts for a very large proportion of electricity production in China. Using a recently developed coarsened exact matching (CEM) technique, this paper examines the impact of research and development (R&D) activities on the performance of firms in China's coal mining industry. Our empirical results reveal that firms in China's coal industry that conduct R&D are more productive and their sales are higher. However, as far as the firm profitability and market shares are concerned, whether or not a firm in China's coal industry conducts R&D makes no difference. We find that foreign direct investment in China's coal mining industry leads to a significant decrease in the market share of domestic firms and its impact on productivity, sales and profitability of domestic firms is insignificant. The empirical results presented in this paper suggest that policies that encourage domestic firms in China's coal mining industries to conduct R&D can increase domestic production thereby reducing reliance on imports. Furthermore, productivity gains arising from R&D activities can also help Chinese mining firms to improve their competitive position in the international market. However, there is a need for restricting foreign direct investment in China's coal mining industry. - Highlights: • R&D status affects firm performance in China's coal mining industry. • Coal mining firms that conduct R&D are, on average, 0.2717% more productive. • Coal mining firms that conduct R&D experience an increase in sales. • Increase in foreign investment decreases the market share of coal mining firms

Bruno, G.A.; Dirks, J.A.; Jackson, P.O.; Young, J.K.

1984-03-01

A review of the US uranium mining industry has revealed a generally depressed industry situation. The 1982 U/sub 3/O/sub 8/ production from both open-pit and underground mines declined to 3800 and 6300 tons respectively with the underground portion representing 46% of total production. US exploration and development has continued downward in 1982. Employment in the mining and milling sectors has dropped 31% and 17% respectively in 1982. Representative forecasts were developed for reactor fuel demand and U/sub 3/O/sub 8/ production for the years 1983 and 1990. Reactor fuel demand is estimated to increase from 15,900 tons to 21,300 tons U/sub 3/O/sub 8/ respectively. U/sub 3/O/sub 8/ production, however, is estimated to decrease from 10,600 tons to 9600 tons respectively. A field examination was conducted of 29 selected underground uranium mines that represent 84% of the 1982 underground production. Data was gathered regarding population, land ownership and private property valuation. An analysis of the increased cost to production resulting from the installation of 20-meter high exhaust borehole vent stacks was conducted. An assessment was made of the current and future /sup 222/Rn emission levels for a group of 27 uranium mines. It is shown that /sup 222/Rn emission rates are increasing from 10 individual operating mines through 1990 by 1.2 to 3.8 times. But for the group of 27 mines as a whole, a reduction of total /sup 222/Rn emissions is predicted due to 17 of the mines being shutdown and sealed. The estimated total /sup 222/Rn emission rate for this group of mines will be 105 Ci/yr by year end 1983 or 70% of the 1978-79 measured rate and 124 Ci/yr by year end 1990 or 83% of the 1978-79 measured rate.

Engineering and the Politics of Commensuration in the Mining and Petroleum Industries

Directory of Open Access Journals (Sweden)

Jessica M. Smith

2018-03-01

Full Text Available Engineers and applied scientists form the backbone of the mining and petroleum industries, yet rarely figure in social science accounts of natural resource extraction. This article begins to fill that gap by ethnographically exploring how community conflicts have prompted engineers and applied scientists working in these industries to reconsider the relationship between the surface and subsurface dimensions of their work. To make social concerns on the surface matter to how drilling and extraction would happen, they tried to make these two domains legible to one another. Using mapping and modeling, they created new techniques for making “social” concerns visible and actionable by field operators, even as they expressed reservations about unduly flattening the inherent complexity of human thought, action, and emotion in the process. While these practices opened space for other engineers and applied scientists to incorporate the concerns of nearby residents into their plans and practices, they also raised questions about the appropriateness of commensuration, or the process of translation through which things and values are made comparable.

Social license to operate: case from brazilian mining industry

Santiago, Ana Lúcia F.; Demajorovic, Jacques; Aledo, Antonio

2015-04-01

The approach of the Social License to Operate (SLO) emerges as an important element in academic discussions and business practices related to extractive industries. It appears that in productive activities with great potential to produce economic, social and environmental impacts, conventional approaches based on legal compliance no longer sufficient to legitimize the actions of companies and engagement stakeholders. Studies highlight the need of mining activities receiving a SLO "issued" by companies stakeholders, including society, government, non-governmental organizations, media and communities. However, local communities appears as major stakeholders in governance arrangements, by virtue of its proximity to extractive areas and ability to affect the company's results. Stakeholders with unmet expectations can generate conflicts and risks to the company, the knowledge of these expectations and an awareness of company managers of the importance of Social License to Operate (SLO), can generate strategies and mitigating actions to prevent and or minimize possible conflicts. The concept of SLO arises in engineering extractive industry, when you need to respond to social challenges, beyond the usual environmental challenges, technological and management. According to Franks and Cohen (2012) there is a tendency of engineering sectors, sustainability, environmental, safety and especially in risk mappings, treat the technological issues in a neutral manner, separating the technological research projects of social influences. I want to contribute to the advancement of the debate on stakeholder engagement and adopting as focus on the company's relationship with the community, the aim of this study was to understand how a social project held by one of the largest mining companies in Brazil contributed to the process of SLO. This methodological procedure adopted was a qualitative, descriptive, and exploratory interviews with the communities located in rural areas of direct

In this article, as determinants in the system factors underlying the investment attractiveness of the peat industry is considered a rental factor, which predetermines the significant differences and peculiarities of the investment climate in the mining business and, in particular, in the sphere of peat mining. In contrast to modern studies treated the essence and role of rents in the economic mechanism, is proposed for a new approach to solving the problems of its formation. Our approach differs in that it, firstly, adequate rental relations, objectively in extractive industries, secondly, provides consensus in the interests of the owner of peat deposits and entrepreneurs, businesses in these deposits and, thus, thirdly, contributes to the creation of a favourable investment climate in the peat extraction industry. In practical terms, in accordance with the proposed approach, we have proposed specific allocation algorithm of mining rents from the profits of peat extraction enterprises.

Managing environmental and health impacts of uranium mining

2014-07-01

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.

The paper summarizes the main findings of a scientific study. Accident figures for the German mining industry indicate that, in comparison with other industries, there is still plenty of scope for increased prevention. However, the rapid development of safety technology alone is still yielding diminishing returns. The main route to increased safety in the mining industry is by way of improved safety management. Various methods are available for analyzing the efficiency of work-safety structures and procedures. Models for the classification of safety-relevant tasks are based on the legally appropriate and organisationally expedient allocation of responsibilities between management and safety experts. An important management tool in this respect is the hazard analysis procedure laid down in the European Union's Health and Safety at Work Act. Practical studies are used to illustrate that safety results can be improved through reorganisation without increasing prime costs. (orig.)

Management of the environment in the uranium mining industry has an eventful history of more than 50 years. In addition to examples of successful restoration of mining and preparation sites in some countries there are also numerous cases, in which no or defective restoration left behind serious waste deposits. In the course of the renaissance of the uranium industry there is increasing interest in the rehabilitation of such waste sites. There is still an urgent requirement to eradicate the environmental effects of the old mining industry. Previous deposits could be of interest for renewed working under the present economic boundary conditions. Restoration as an integral part of the current and future uranium mining industry with the application of modern international safety standards is extremely important. The contribution provides a survey of restoration projects of the old mining industry in various parts of the world and shows how the International Atomic Energy Agency, the national supervisory and approval authorities as well as the mining companies collaborate closely at many sites on solution of the difficult problems.

Trackless battery powered haulage vehicles have been in operation in British coal mines principally for longwall face transfer and personnel transportation. Changes within the industry have resulted in the introduction of room and pillar coal mining methods and the introduction of increasingly heavier longwall roof supports. This has resulted in the introduction of: battery powered coal haulage machines, which, without the need for trailing cables, increase productivity within room and pillar mining; and battery powered longwall shield haulers which are capable of carrying the heaviest shield supports currently being utilised within the British coal mining industry. The conventional machines have been adapted from an American design to meet the requirements of European legislation. This has seen the emphasis being placed upon the supplier with the European Machinery Directive being introduced, necessitating the assigning of a `CE` mark to each vehicle. Battery vehicle technology has advanced to meet the demands of the ever changing market and will no doubt be further adapted to meet the requirement of the British coal mining industry. 1 ref., 12 figs., 3 tabs.

Machine-related injuries in the US mining industry and priorities for safety research.

Ruff, Todd; Coleman, Patrick; Martini, Laura

2011-03-01

Researchers at the National Institute for Occupational Safety and Health studied mining accidents that involved a worker entangled in, struck by, or in contact with machinery or equipment in motion. The motivation for this study came from the large number of severe accidents, i.e. accidents resulting in a fatality or permanent disability, that are occurring despite available interventions. Accident descriptions were taken from an accident database maintained by the United States Department of Labor, Mine Safety and Health Administration, and 562 accidents that occurred during 2000-2007 fit the search criteria. Machine-related accidents accounted for 41% of all severe accidents in the mining industry during this period. Machinery most often involved in these accidents included conveyors, rock bolting machines, milling machines and haulage equipment such as trucks and loaders. The most common activities associated with these accidents were operation of the machine and maintenance and repair. The current methods to safeguard workers near machinery include mechanical guarding around moving components, lockout/tagout of machine power during maintenance and backup alarms for mobile equipment. To decrease accidents further, researchers recommend additional efforts in the development of new control technologies, training materials and dissemination of information on best practices.

Full Text Available Following the Japanese victory over Czarist Russia in the Russo-Japanese War and the signing of the Treaty of Portsmouth in 1905, the southernmost section of the southern branch of the China Far East Railway (Changchun–Port Arthur was transferred to Japanese control. A new, semi-privately held company, the South Manchuria Railway Company (SMR, Mantetsu, was established with 85.6 percent capitalization by the Japanese government and foreign bonds to operate the railroad and to develop settlements (including highways, public health facilities, educational institutions, and industries (coal mines, harbor facilities, electrical power plants, shale oil plants, chemical plants, and restaurants along its route. SMR nonetheless emphasized railway and mining investment. The centerpiece of its mining interests was the Fushun Coal Mine. Starting in 1917, SMR began to prosper, with most profits coming from its coal mines, and it soon spun off subsidiary companies. In this sense, although the factors that influenced development of the Fushun Coal Mine in each period were different, this development still shows continuity of the business management.

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.

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.

Feasibility of Applying Clean Development Mechanism and GHGs Emission Reductions in the Gold Mining Industry: A Case of Thailand

2015-12-01

There is presently overwhelming scientific consensus that global climate change is indeed occurring, and that human activities are the primary driver. An increasingly resource and carbon constrained world will continue to pose formidable challenges to major industries, including mining. Understanding the implications of climate change mitigation for the mining industry, however, remains limited. This paper presents the results of a feasibility study on the implementation of a clean development mechanism and greenhouse gases (GHGs) emission reductions in the gold mining industry. It draws upon and extends the analysis of a case study conducted on gold mining operations in Thailand. The results from the case study indicated that total GHGs emissions by company A were approximately 36,886 tons carbon dioxide equivalents (tCO2e) per annual gold production capacity that meet the eligibility criteria for small-scaled clean development mechanism (CDM) projects. The electrostatic separation process was found to release the lowest amount of GHGs, whereas comminution (i.e. crushing and grinding) generated the highest GHGs emissions. By scope, the emission from purchased electricity (scope 2) is the most significant source. Opportunities for CDM projects implementation in the gold mining sector can be found in employing energy efficiency measures. Through innovation, some technical efficiency and technological development in gold processing (i.e. high pressure grinding rolls (HPGR), vertical roller mills (VRM), gravity pre-concentration and microwave heating technologies) that have the potential to reduce energy use and also lower carbon footprint of the gold mining were further discussed. The evidence reviews found that HPGR and VRM abatement technologies have shown energy and climate benefits as electricity savings and CO2 reduction of about 8-25.93 kWh/ton ore processed and 1.8-26.66 kgCO2/ton ore processed, respectively. Implications for further research and practice were

Slabinskiy, V T

1980-01-01

Mining enrichment enterprises of the ferrous and nonferrous metallurgy, coal and chemical industry have much in common in the area of technology of production, technical base, organization of labor and production. This in turn presupposes the possible development of a common procedure of accounting of expenditures for production, calculation of net cost of output and analysis of production-economic activity of enterprises. Based on scientific research and generalization of advanced experience of practical workers, means of improvement of economic operation in mining enrichment enterprises are outlined according to increasing demands of production control. An outline of analytic accounting of expenditures which provides for multitarget use of information has been developed: for organization of operational control of the formulation of net cost of output, determination of the results of self support activities of structural subdivisions of an enterprise, computation of the efficiency of scientific and technical progress. Experience of use of economic and mathematical methods in computers for this purpose is discussed.

2017-01-01

Misclassification of ore grades results in lost revenues, and the need for representative sampling procedures in open pit mining is increasingly important in all mining industries. This study evaluated possible improvements in sampling representativity with the use of Reverse Circulation (RC) drill...... sampling compared to manual Blast Hole (BH) sampling in the Leveäniemi open pit mine, northern Sweden. The variographic experiment results showed that sampling variability was lower for RC than for BH sampling. However, the total costs for RC drill sampling are significantly exceeding current costs...... for manual BH sampling, which needs to be compensated for by other benefits to motivate introduction of RC drilling. The main conclusion is that manual BH sampling can be fit-for-purpose in the studied open pit mine. However, with so many mineral commodities and mining methods in use globally...

Alexander, E.G.; Stewart, N.D.; Wallace, B.J.

1993-01-01

It is shown that the introduction of uniform Australian national Codes of Practice for radiation protection in the mining and milling of radioactive ores in the early 1980's has led to the mining and health regulatory authorities implementing the provisions of the Codes. Deficiencies involving dust and external gamma radiation levels in the mineral sands industry have led to various administrative and engineering controls being introduced to reduce the levels of radiation doses to employees well below 20 mSv/y limit. There are guidelines for screening the radioactivity of tailings released into the environment and some products for industrial use. Future activities by the regulatory authorities and industry will involve an optimisation of radiation protection, ongoing remedial programs, register of data about contaminated lands and assessments of the environmental, occupational and the public radiological impacts from downstream processing of mineral sands. The latter involves synthetic rutile, zircon flour, rare earth and refractory technologies. 7 refs., 1 tab., 1 fig

Germany is a high-wage country. Hence the internationally competitive extraction of raw materials in Germany can only be ensured by highly efficient working processes. Tackling the associated extreme requirements on road-driving, coal winning and transport equipment has resulted in the German mining industry and its suppliers achieving the role of an international leader in technology. To safeguard this position also in the future the successful mechanisation will now be followed by the mechatronisation in the mining industry. Efficiency will be increased by (partial) automation and assistance systems. This contribution is a first step towards a series of articles, which explain the principles of mechatronic development methods in the mining industry and will make the development engineers in the mines aware of the high potential of mechatronics in the mining industry.

Women in mining still exploited and sexually harassed

Directory of Open Access Journals (Sweden)

Doret Botha

2016-11-01

Full Text Available Orientation: Globally, women have become an essential part of the mining workforce. Among other jobs, they fulfil management positions, operate heavy machinery and are involved in artisanal mining processes. In South Africa, new mining legislation not only prohibits the exclusion of women but requires from companies to actively change the demographic profile of their workforce. Mining companies are obliged to also employ women in core mining activities. Although well intended, women appointed in core positions work side by side with men, often in isolation, and are frequently at risk of sexual abuse and/or harassment. Research purpose: This research determined perceptions regarding the occurrence of sexual harassment among women working in core mining positions. Motivation for the study: Currently, there is a paucity of published data on the occurrence of sexual harassment in the mining industry. Method: A mixed-method research design was used including quantitative and qualitative research paradigms. Quantitative data were collected by means of a structured questionnaire. Qualitative data were collected by means of individual and group interviews. Main findings: From the literature review and the empirical findings, it is evident that women are still exploited and sexually harassed in the mining industry. Incidents taking place on a daily basis vary from whistling; name calling; use of vulgar or derogatory language; display of body parts; physical contact, ranging from touching to sexual assault and rape; to the exchange of sexual favours for promotion. Practical/managerial implications: It is evident from the research that a holistic approach is required to effectively eradicate sexual harassment in the mining industry, involving the commitment of relevant state departments, human resource managers and labour experts. Contribution: Practical recommendations are made to effectively address sexual harassment in the mining industry.

A clean environment approach to uranium mining

International Nuclear Information System (INIS)

Grancea, Luminita

2015-01-01

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

The mining industry and the community: Joining forces for sustainable social development

International Nuclear Information System (INIS)

Labonne, B.

1999-01-01

This article joins the continuing policy debate over the social responsibility of corporations, particularly in the mining industry. The author argues that the 'old school mining orthodoxy' - approaching the exploitation of mineral deposits solely from the technical and economic points of view-is long dead. Mining companies must also encompass the social dimension. New policies for the mining industry are discussed in terms of recent worldwide trends and movements, e.g. globalization, economic interdependence and decentralization of governmental authority, and the rise of civil society as a political factor. These trends, together with the United Nations policies in quest of sustainable development and the consensus expressed at international conferences during the last decade, have deepened social awareness and set the stage for enhanced social responsiveness from the private sector. Socially responsible corporate policies include decentralization of decision-making to the field level, reaching out to stake holders and shareholders, supporting governments which provide official development assistance for good governance and building broad partnerships to reduce social exposures.

2015-03-31

In response to recent diplomatic developments between Cuba and the United States, the National Minerals Information Center compiled available information on the mineral industries of Cuba. This fact sheet highlights a new map and table that identify mines, mineral processing facilities, and petroleum facilities as well as information on location, operational status, and ownership. It also addresses the current status of known mineral industry projects, historical developments, and trends of the Cuban economy with an emphasis on mineral industries, and the supply and demand for Cuba’s mineral resources.In 2013, Cuba was estimated to be among the world’s top ten producers of cobalt and nickel, which are the country’s leading exports. Cuba’s current crude oil and associated natural gas production from onshore and shallow water coastal reservoirs is approximately 50,000 barrels per day of liquids and about 20,000 barrels per day oil equivalent of natural gas. In 2013, the value of mining and quarrying activities accounted for 0.6 percent of Cuba’s gross domestic product (GDP), compared with 1.4 percent in 2000. The value of production from Cuba’s industrial manufacturing sector increased by 88 percent between 1993 and 2013, whereas the sector’s share in the GDP decreased by about 3 percent during the same time period reflecting economic growth in other sectors of the economy.

Ecological security is an important issue for sustainable development of mining industry, on which the development of nuclear industry and nuclear power is based. But uranium mining and processing has larger effect on ecological environment which mainly include tailings, waste rock, waste water, and radiation effects. In this paper, the dialectical relationship between ecological security and sustainable relationship is analyzed, the ecological safety concept at home and abroad is compared and the role that ecological safety plays in the sustainable development of uranium mining based on analysis of restricting factors on uranium mining in China from the perspective of ecological security is also probed into. To achieve sustainable development of the uranium mining industry in China, an ecological security concept from four aspects must be established: 1) the concept of ecological security management; 2) the scientific concept of ecological security; 3) the concept of ecological security investment; and 4) the concept of ecological security responsibility.

Fry, R.M.

1992-01-01

Significant radiological protection problems arise in the mining and processing of uranium and thorium bearing ores, beach sands and other materials that have enhanced levels of uranium (e.g. phosphate). They are at their most extreme in the underground mining of uranium. Under the new ICRP 60 occupational dose limits it may be necessary to subject virtually all mining operations to some degree of radiological surveillance. There are three principal modes of radiation exposure in uranium mining operations: gamma rays, an external whole body radiation hazard; the inhalation of radon daughter products; and the inhalation of ore dust containing the long-lived alpha emitting daughter products of uranium, principally 230Th and 226Ra. A number of the new recommendations in ICRP60 considered to have significant implications for the mining industry in general and the above mentioned issues in particular are discussed. These include the definition of occupational exposure occupational dose limit, the review of the radon dose limits, the system of radiological protection. The major conclusions and recommendation of the IAEA Technical Committee to Explore the Impact of the new ICRP Occupational Dose Limits in the operation of underground mines are also summarized. 18 refs., 1 tab

Domestic uranium mining and milling industry 1989

International Nuclear Information System (INIS)

1990-01-01

Section 170B of the Atomic Energy Act of 1954, as amended by Public Law 97-415, requires that the Secretary of Energy submit to Congress an annual assessment of the viability of the domestic uranium mining and milling industry. The Energy Information Administration (EIA) of the Department of Energy (DOE) was assigned the responsibility to develop the criteria for use in estimating the viability of the industry. These criteria include four major attributes of industry viability - resource capability, supply response capability, financial capability, and import commitment dependency. Having established these criteria, the Secretary of Energy is required to monitor the industry and make an annual assessment of its viability for 1983 through 1992. The first six assessments were issued in the years 1984 through 1989 based on information available for 1983 through 1988, respectively. The current report provides the data and analyses, based on the information available through the end of the calendar year 1989, supporting the seventh annual assessment of the uranium industry's viability. It presents information on the four major attributes. Data on past and present industry behavior, as well as projections of the future status of the industry (assuming current market conditions), were used to examine the industry's ability to respond, over a 10-year period, to two hypothetical supply disruption scenarios. 20 figs., 23 tabs

Construction accident research involves the systematic sorting, classification, and encoding of comprehensive databases of injuries and fatalities. The present study explores the causes and distribution of occupational accidents in the Taiwan construction industry by analyzing such a database using the data mining method known as classification and regression tree (CART). Utilizing a database of 1542 accident cases during the period 2000-2009, the study seeks to establish potential cause-and-effect relationships regarding serious occupational accidents in the industry. The results of this study show that the occurrence rules for falls and collapses in both public and private project construction industries serve as key factors to predict the occurrence of occupational injuries. The results of the study provide a framework for improving the safety practices and training programs that are essential to protecting construction workers from occasional or unexpected accidents.

Lignite industry in Greece within a world context: Mining, energy supply and environment

International Nuclear Information System (INIS)

Kavouridis, Konstantinos

2008-01-01

Today coal covers 38% of global production and roughly 30% of the EU-25 power output. In 2005 domestic lignite with a share of 60.5% in power generation and accounting about 30% of primary energy consumption is currently the most important indigenous fuel of Greece. Greece, mining 70 Mt annually, is the second lignite producer in the EU and fourth in the world. Approximately 97% of the lignite used to supply the existing lignite-fired power plants of Greece is mined by Public Power Corporation S.A. (PPC). Lignite as the base load fuel gives a competitive strength in PPC's and Greece's fuel mix. Due to lignite consumer prices in Greece are significantly below those in other comparable markets in EU-15. Extraction of lignite has a very long tradition. Significant achievements and large experience which has been gained during many years of mining operations place Greek lignite-mining industry in the leading position in Europe. The paper presents current state of Greek lignite industry, including operating mines, volume of production and other important production indicators as well as improvements in labor productivity and good results in industrial safety. The future of coal and specifically of Greek lignite will be crucially determined by environmentally compatible, i.e. low-CO 2 generation of electricity. Investment in modernization and renewal of the power plant fleet are the key to securing electricity supply and progress in preventing climate change

Ecological restoration of mineland with particular reference to the metalliferous mine wasteland in China: A review of research and practice.

Science.gov (United States)

Li, M S

2006-03-15

Despite a principal contributor to the rapid economic growth, the mining industry in China produced a large amount of wasteland and caused water pollution and soil erosion as well as other environmental damages. In 2002, this industry generated 265.4 Mt tailings, 130.4 Mt gangue and 107.8 Mt smelting slags. The degraded land associated with mining is estimated to be 3.2 Mha by the end of 2004, deteriorating the land shortage of China. Restoration of mine wasteland began in late 1970s but the restoration process was sluggish. The overall restoration rate (the ratio of reclaimed land area to the total degraded land area) of mine wasteland was some 10-12% with a higher rate for coal mine spoils but a lower rate for metal-mined derelict land. From 1994 to 2004, 149 research papers were published about the restoration of China's mining wasteland, of which 70 were on metal-mined land and 61 on the non-metal-mined land. Although 37 institutions in China were involved in the restoration research, only a few remained active and productive. Metal-mined derelict land is often more metal toxic and deficient of macronutrients and is tougher for revegetation. Many substrate amelioration techniques were proposed and tolerant plant species were tested for use of reclamation of the metal-mined tailings. Five hyperaccumulator species have been reported in China for the potential use in phytoremediation. However, these accomplishments were all at laboratory or small-scale field demonstration stage and still far from the practical use in reality. To accelerate the restoration and utilization of mine wasteland, several recommendations are put forward in this review. Above these suggestions, the commitment and efficiency of the government at all levels are vital.

2017-01-01

Full Text Available The mining industry is showing increasing interest in using renewable energy (RE technologies as one of the principles of sustainable mining. This is witnessed in several pilot projects in major mining countries around the world. Positive factors which favor this interest are gaining importance and negative barrier factors seem to be less relevant. For a mine operator, the switch from fossil fuel to RE technologies is the outcome of decision making processes. So far, research about such decision making on the use of RE in mining is underdeveloped. The purpose of this paper to present a practical decision rule based on a principle of indifference between RE and fossil fuel technologies and on appropriate time management. To achieve this objective, three investigations are made: (i a case studies analysis, (ii a comparative cost analysis, and (iii a SWOT analysis.

Australia has a long history of uranium mining. Most of the early production came from Rum Jungle in the Northern Territory and Mary Kathleen in Queensland. The second generation of uranium mines (Ranger, Nabarlek and Olympic Dam) came on line in the 1970s and 1980s at a time of increased environmental awareness and public scrutiny. The waste management practices at these mines are in accordance with best practicable technology for the uranium mining industry. This paper describes Australia's experience in managing the front end of the fuel cycle; uranium mining and ore processing. (orig.)

A Review of Mine Rescue Ensembles for Underground Coal Mining in the United States.

Science.gov (United States)

Kilinc, F Selcen; Monaghan, William D; Powell, Jeffrey B

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

Applying a small NPP in the Argentine mining industry

Barrientos, C.J.; Masriera, N.A.

1998-01-01

The CAREM 25 reactor project is a small PWR nuclear power plant of 27 MWe, based on advanced concepts: a self-pressurized integral primary with natural convection of the coolant and a more simple and reliable general design. The CAREM concept has many advantages as a power generator in small electrical grids. Besides, there are some non-electrical applications under consideration, since a co-generation scheme seems very interesting from the economical point of view. In this category two alternatives have been considered: a standard desalination facility and a process plant in the mining industry. In this paper, a conceptual analysis of the second alternative is presented. Mining is a branch of the domestic industry that has shown a remarkable growth in the past three years mainly due to a steady inflow of foreign investments (about two billion dollars for that period). And one of the most attractive markets is in the extraction and manufacturing of non-ferrous minerals, coming from deposits in the northwest of Argentina: sodium sulfate, lithium salts, and boron compounds. Nevertheless it faces an unsolved problem in the energy high prices due to the fact that the production sites are located in remote areas where the only achievable energy source is the transportation of fuel oil. In this scenario, a small NPP may be a competitive source of process heat and electricity, with enough autonomy to uncouple fuel requirements from production strategies. The present study analyses the possible application of the CAREM concept in the non-ferrous mining industry of the Northwest of Argentina, considering a co-generation scheme. The main results of this analysis and the inherent advantages of the approach, show that the alternative may be feasible both from the technical and the economical points of view. (author)

Nuclear-geophysical methods as a basis of progressive technology of ore quality control in mining industry

International Nuclear Information System (INIS)

Mejer, V.A.

1976-01-01

The significance of nuclear physics methods in the mining industry is demonstrated using examples of applying the X-ray diffraction method to the delimitation of lead-zinc and tin ores in exploratory wells, faces of mine workings and to a quick estimation of metal contents in hacked-off rocks and market payable ore. Their implementation at all stages of the exploration and development of deposits would improve the extraction of ores and reduce losses of the raw material during technological treatment. Owing to the rapidity and operativeness of control over the quality of ores at all stages of geological prospecting and mining, nuclear physics methods can provide a basis for technological progress in the mining industry

2008-10-01

Full Text Available Abstract Background The mining industry has one of the highest occupational rates of serious injury and fatality. Mine staff involved with rescue operations are often required to respond to physically challenging situations. This paper describes the physical attributes of mining rescue personnel. Methods 91 rescue personnel (34 ± 8.6 yrs, 1.79 ± 0.07 m, 90 ± 15.0 kg participating in the Queensland Mines Rescue Challenge completed a series of health-related and rescue-related fitness tasks. Health-related tasks comprised measurements of aerobic capacity (VO2max, abdominal endurance, abdominal strength, flexibility, lower back strength, leg strength, elbow flexion strength, shoulder strength, lower back endurance, and leg endurance. Rescue-related tasks comprised an incremental carry (IC, coal shovel (CS, and a hose drag (HD, completed in this order. Results Cardiovascular (VO2max and muscular endurance was average or below average compared with the general population. Isometric strength did not decline with age. The rescue-related tasks were all extremely demanding with heart rate responses averaging greater than 88% of age predicted maximal heart rates. Heart rate recovery responses were more discriminating than heart rates recorded during the tasks, indicating the hose drag as the most physically demanding of the tasks. Conclusion Relying on actual rescues or mining related work to provide adequate training is generally insufficient to maintain, let alone increase, physical fitness. It is therefore recommended that standards of required physical fitness be developed and mines rescue personnel undergo regularly training (and assessment in order to maintain these standards.

A case in support of implementing innovative bio-processes in the metal mining industry.

The metal mining industry faces many large challenges in future years, among which is the increasing need to process low-grade ores as accessible higher grade ores become depleted. This is against a backdrop of increasing global demands for base and precious metals, and rare earth elements. Typically about 99% of solid material hauled to, and ground at, the land surface currently ends up as waste (rock dumps and mineral tailings). Exposure of these to air and water frequently leads to the formation of acidic, metal-contaminated run-off waters, referred to as acid mine drainage, which constitutes a severe threat to the environment. Formation of acid drainage is a natural phenomenon involving various species of lithotrophic (literally 'rock-eating') bacteria and archaea, which oxidize reduced forms of iron and/or sulfur. However, other microorganisms that reduce inorganic sulfur compounds can essentially reverse this process. These microorganisms can be applied on industrial scale to precipitate metals from industrial mineral leachates and acid mine drainage streams, resulting in a net improvement in metal recovery, while minimizing the amounts of leachable metals to the tailings storage dams. Here, we advocate that more extensive exploitation of microorganisms in metal mining operations could be an important way to green up the industry, reducing environmental risks and improving the efficiency and the economy of metal recovery. © FEMS 2016.

The ''Heat Market Campaign'', presented in June '83 by experts of all fields of coal mining, investigates the possibilities of coal sales promotion. The article reviews the main data of the heat market and discusses the ''Heat Market Campaign'' under the aspects of coal policy and energy policy. The campaign was started with the objectives of energy supply assurance in the Federal Republic of Germany, energy cost reduction on the consumer side, and stabilisation and development of coal markets not affected by the steel crisis. Sales goald on the household, trade and industrial sector are quantified, and obstacles preventing further expansion of the heat market are discussed. Apart from the mining industry's marketing concept for the heat market, there is also the possibility of receiving financial aid by the Federal government.

Environmental Impacts and Health Aspects in the Mining Industry. A Comparative Study of the Mining and Extraction of Uranium, Copper and Gold

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

Perceptions and Realities in Modern Uranium Mining - Extended Summary

International Nuclear Information System (INIS)

2014-01-01

Uranium mining and milling has evolved significantly over the years. By comparing currently leading approaches with outdated practices, the report demonstrates how uranium mining can be conducted in a way that protects workers, the public and the environment. Innovative, modern mining practices combined with strictly enforced regulatory standards are geared towards avoiding past mistakes made primarily during the early history of the industry when maximising uranium production was the principal operating consideration. Today's leading practices in uranium mining aim at producing uranium in an efficient and safe manner that limits environmental impacts to acceptable standards. As indicated in the report, the collection of baseline environmental data, environmental monitoring and public consultation throughout the life cycle of the mine enables verification that the facility is operating as planned, provides early warning of any potentially adverse impacts on the environment and keeps stakeholders informed of developments. Leading practice also supports planning for mine closure before mine production is licensed to ensure that the mining lease area is returned to an environmentally acceptable condition. The report highlights the importance of mine workers being properly trained and well equipped, as well as that of ensuring that their work environment is well ventilated so as to curtail exposure to radiation and hazardous materials and thereby minimise health impacts.

Using MSD prevention for cultural change in mining: Queensland Government/Anglo Coal Industry partnership.

Science.gov (United States)

Tilbury, Trudy; Sanderson, Liz

2012-01-01

Queensland Mining has a strong focus on safety performance, but risk management of health, including Musculoskeletal Disorders (MSDs) continues to have a lower priority. The reliance on individual screening of workers and lower level approaches such as manual handling training is part of the coal mining 'culture'. Initiatives such as the New South Wales and Queensland Mining joint project to develop good practice guidance for mining has allowed for a more consistent message on participatory ergonomics and prevention of MSD. An evidence based practice approach, including the introduction of participatory ergonomics and safe design principles, was proposed to Anglo American Coal operations in Queensland. The project consisted of a skills analysis of current health personnel, design of a facilitated participatory ergonomics training program, site visits to identify good practice and champions, and a graduated mentoring program for health personnel. Early results demonstrate a number of sites are benefiting from site taskforces with a focus on positive performance outcomes.

Integrated mined-area reclamation and land-use planning. Volume 3C. A case study of surface mining and reclamation planning: Georgia Kaolin Company Clay Mines, Washington County, Georgia

Guernsey, J L; Brown, L A; Perry, A O

1978-02-01

This case study examines the reclamation practices of the Georgia Kaolin's American Industrial Clay Company Division, a kaolin producer centered in Twiggs, Washington, and Wilkinson Counties, Georgia. The State of Georgia accounts for more than one-fourth of the world's kaolin production and about three-fourths of U.S. kaolin output. The mining of kaolin in Georgia illustrates the effects of mining and reclaiming lands disturbed by area surface mining. The disturbed areas are reclaimed under the rules and regulations of the Georgia Surface Mining Act of 1968. The natural conditions influencing the reclamation methodologies and techniques are markedly unique from those of other mining operations. The environmental disturbances and procedures used in reclaiming the kaolin mined lands are reviewed and implications for planners are noted.

Sustainable Land Management in Mining Areas in Serbia and Romania

2015-08-01

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.

Occupational dermatoses in the uranium mining and processing industry

Energy Technology Data Exchange (ETDEWEB)

Sevcova, M [Zavodni Ustav Narodniho Zdravi Uranoveho Prumyslu, Pribram (Czechoslovakia)

1978-04-01

Experience gained so far by the Department of Dermatovenerology in the uranium industry discloses that the incidence of occupational dermatoses is relatively low in this industry. It represents about 1% of all newly ascertained skin diseases per year. Allergic contact eczemas after having been in contact with rubber products, chiefly rubber boots, predominate. Under the working conditions in mining and preparing uranium ore, ionizing radiation cannot induce non-stochastic effects of the type of radiation dermatitis on the skin. A higher incidence was, however, ascertained in uranium miners of basaliomas, which agrees with the estimation of the dose of external alpha radiation in the basal epidermis layer.

Applications of radio frequency identification systems in the mining industry

1995-07-01

Radio Frequency Identification Systems (RFID) are one of the automatic data capture technologies taking over from bar codes and magnetic swipe cards in many applications involving automatic hands free operation in arduous environments. RFID systems are based on the use of miniature radio transponders carrying encoded electronic data that is used to uniquely identify the identity of transponders. This paper reviews the types of system available and compares the various techniques involved in the different systems. The various types of transponder are described including the latest state of the art passive read/write high performance types. A review of the history of RFID systems in the mining industry is also given in the paper. The problems involved in designing and certifying a system for use in hazardous areas are also described, with particular reference to the problems of inadvertent detonator ignition by radio systems. Applications of RFID systems in the mining industry are described in considerable detail, covering applications both on the surface and underground. 1 ref., 12 figs., 1 tab.

A review of 100 years of protection against disasters in the coal mining industry impressively shows the way from an era of major accidents to a modern branch of industry, which justifiably and with good prospects of success can pursue the aim of ''No accidents - no damage to health - no damage to the environment''. However, the development of the mine rescue service over more than 100 years - represented in the Ruhr by the Main Mine Rescue Service established in 1910 in Essen - would be incomplete without consideration of the allied technical fields underground fire protection and explosion protection. Cooperation between institutions such as the Tremonia test mine and the BVG has produced a safety level in all three fields, which is regarded as exemplary worldwide, and in addition to the latest mining technology is a good advertisement for the German coal mining industry.

Weber, B.

1992-01-01

The potentials and deficiencies of the mining components supplying industry are assessed by means of an industry study. Development prospects are derived for the mining sector. While individual solutions are neglected, methods which support the mining companies' efforts at diversifying and at opening up new markets are discussed placing emphasis on a sociocompatible implementation of the inevitable structural change and on the maintenance of a qualified industrial basis in communities dominated by the mining components supplying industry. The possibilities of cooperation between the companies are discussed, and conceivable future prospects are derived for the mining sector. (HS) [de

Environmental Management Practices and Firm Performance in a South African Mining Firm

Directory of Open Access Journals (Sweden)

2013-09-01

Full Text Available This paper examines the impact of environmental management practices on the financial performance of a South African mining firm. 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.

Uranium mining in the Canadian social environment in the eighties

International Nuclear Information System (INIS)

Dory, A.B.

1982-01-01

The Canadian Atomic Energy Control Board considers the health and safety of workers and members of the public to be of primary concern in the assessment of any proposed uranium mine or mill. Of great importance also is the influence mining practices may have on waste streams, subsequent waste management, and consequently the environment. Past mistakes and the reluctance of mining companies to talk openly to the public have resulted in the loss of credibility of the uranium mining industry. The public is subjected to the biased views of nuclear critics and does not have a balanced picture of the industry. The health hazards of radiation are generally overstated, and society is not willing to accept the small risks associated with nuclear power. Complete openness on the part of the industry and regulatory agencies will be required in order to regain public confidence

A parcimonious long term model is proposed for a mining industry. Knowing the dynamics of the global reserve, the strategy of each production unit consists of an optimal control problem with two controls, first the flux invested into prospection and the building of new extraction facilities, second the production rate. In turn, the dynamics of the global reserve depends on the individual strategies of the producers, so the models leads to an equilibrium, which is described by low dimensional systems of partial differential equations. The dimensionality depends on the number of technologies that a mining producer can choose. In some cases, the systems may be reduced to a Hamilton–Jacobi equation which is degenerate at the boundary and whose right hand side may blow up at the boundary. A mathematical analysis is supplied. Then numerical simulations for models with one or two technologies are described. In particular, a numerical calibration of the model in order to fit the historical data is carried out.

2005-07-01

A data mining application for lighting energy audits at industrial sites was presented. Data collection was based on the parameters needed for the analysis part of the audit. Data collection included the activity for which the room was used; its dimension; light level readings in lux; the number of luminaries; the number of lamps per luminaries; lamp fixtures; and lamp wattage. The lumen method was used to calculate the recommended numbers of luminaries in the room. The number was then compared with the existing system's luminaries. The installed load efficacy ratio (ILER) was then used to determine proper retrofit action to maximize energy usage. The difference between the calculated lux and the standard lux was used to create data subsets. A data mining algorithm was used to determine that the ILER plays an important role in calculating the efficiency of lighting systems. It was also concluded that the method can be used to minimize the time needed to analyze large amounts of lighting data. The results of case studies were also used to show that the combined data mining algorithm provided accurate assessments using existing calculated data. 7 refs., 8 tabs., 5 figs.

In an effort to address air quality concerns in underground mines, the mining industry is considering the use fuel cells instead of diesel to power mine production vehicles. The immediate issues and opportunities associated with fuel cells use include a reduction in harmful greenhouse gas emissions; reduction in ventilation operating costs; reduction in energy consumption; improved health benefits; automation; and high productivity. The objective of the hydrogen mine introduction initiative (HMII) is to develop and test the range of fundamental and needed operational technology, specifications and best practices for underground hydrogen power applications. Although proof of concept studies have shown high potential for fuel cell use, safety considerations must be addressed, including hydrogen behaviour in confined conditions. This presentation highlighted the issues to meet operational requirements, notably hydrogen production; delivery and storage; mine regulations; and hydrogen behaviour underground. tabs., figs.

Water is a very important natural resource which can be utilized in renewable or non-renewable forms but before utilizing, the evaluation of the quality of this resource is crucial for a particular use. However, the problems of water quality are more severe in areas where the mining and mineral processes' industries are present. In mining processes, several classes of wastes are produced which may turn into ultimately the sources of water quality and environmental degradation. In consequences, the evaluations of water quality for livestock, drinking, irrigation purposes and environmental implications have been carried out around the Barapukuria Coal Mining Industry under different methods and techniques such as primarily the field investigation; secondly the laboratory chemical analysis and thirdly justified the suitability of the laboratory analysis with statistical representation and correlation matrix, Schoeller plot, Piper's Trilinear diagram, Expanded Durov diagram, Wilcox diagram, US salinity diagram, Doneen's chart and others. The results of all surface and ground water samples analysis show that the characteristics and concentrations of all the major physical and chemical parameters such as pH, EC, TDS, Na+, K+, Ca2+, Mg2+, Fetotal, Cl-, HCO3 -, CO3 2- and SO4 2- are varied from one sample to other but well analogous with the WHO and EQS standard limit for all purposes in the area where the abundance of the major ions is as follows: Ca2+ > Na+ > Mg2+ > K+ > Fetotal = HCO3 - > SO4 2- > Cl- > CO3 2-. The graphical exposition of analytical data demonstrates two major hydrochemical facies for example: calcium-bicarbonate (Ca2+- HCO3 -) and magnesium-bicarbonate (Mg2+- HCO3 -) type facies which directly support the shallow recently recharged alkaline water around the industry. The calculated values for the evaluation classification of water based on TDS, Na%, EC, SAR, PI, RSC, MH, and TH replicate good to excellent use of water for livestock, drinking and

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.

Restoring Forests and Associated Ecosystem Services on Appalachian Coal Surface Mines

Science.gov (United States)

Zipper, Carl E.; Burger, James A.; Skousen, Jeffrey G.; Angel, Patrick N.; Barton, Christopher D.; Davis, Victor; Franklin, Jennifer A.

2011-05-01

Surface coal mining in Appalachia has caused extensive replacement of forest with non-forested land cover, much of which is unmanaged and unproductive. Although forested ecosystems are valued by society for both marketable products and ecosystem services, forests have not been restored on most Appalachian mined lands because traditional reclamation practices, encouraged by regulatory policies, created conditions poorly suited for reforestation. Reclamation scientists have studied productive forests growing on older mine sites, established forest vegetation experimentally on recent mines, and identified mine reclamation practices that encourage forest vegetation re-establishment. Based on these findings, they developed a Forestry Reclamation Approach (FRA) that can be employed by coal mining firms to restore forest vegetation. Scientists and mine regulators, working collaboratively, have communicated the FRA to the coal industry and to regulatory enforcement personnel. Today, the FRA is used routinely by many coal mining firms, and thousands of mined hectares have been reclaimed to restore productive mine soils and planted with native forest trees. Reclamation of coal mines using the FRA is expected to restore these lands' capabilities to provide forest-based ecosystem services, such as wood production, atmospheric carbon sequestration, wildlife habitat, watershed protection, and water quality protection to a greater extent than conventional reclamation practices.

Data mining applications in healthcare.

Science.gov (United States)

Koh, Hian Chye; Tan, Gerald

2005-01-01

Data mining has been used intensively and extensively by many organizations. In healthcare, data mining is becoming increasingly popular, if not increasingly essential. Data mining applications can greatly benefit all parties involved in the healthcare industry. For example, data mining can help healthcare insurers detect fraud and abuse, healthcare organizations make customer relationship management decisions, physicians identify effective treatments and best practices, and patients receive better and more affordable healthcare services. The huge amounts of data generated by healthcare transactions are too complex and voluminous to be processed and analyzed by traditional methods. Data mining provides the methodology and technology to transform these mounds of data into useful information for decision making. This article explores data mining applications in healthcare. In particular, it discusses data mining and its applications within healthcare in major areas such as the evaluation of treatment effectiveness, management of healthcare, customer relationship management, and the detection of fraud and abuse. It also gives an illustrative example of a healthcare data mining application involving the identification of risk factors associated with the onset of diabetes. Finally, the article highlights the limitations of data mining and discusses some future directions.

Quantitative risk-based approach for improving water quality management in mining.

Science.gov (United States)

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.

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)

In the face of the frequent occurrence of coal mine safety accidents, this paper analyses the relationship between central and local governments, coal mining enterprises and miners from the perspective of multi - group game. In the actual production, the decision of one of the three groups can affect the game strategy of the other of the three, so we should assume the corresponding game order. In this order, the game analysis of the income and decision of the three is carried out, and the game decision of the government, the enterprise and the workers is obtained through the establishment of the benefit matrix and so on. And then on the existing system to optimize the coal industry regulation proposed practical recommendations to reduce the frequency of industry safety accidents, optimize the industry production environment.

Practical difficulties in determining 222Rn flux density in underground uranium mines

International Nuclear Information System (INIS)

Bigu, J.

1991-01-01

Radon-222 flux density, J, has been determined in a number of locations in an underground U mine. Measurements were conducted using the Two-Point Measurement (2PM) method, consisting of measuring the 222Rn concentration at two different points a distance apart within a given section of the mine. Several mine models were used for determining J by the above method. The 2PM method is sensitive to sources and sinks of 222Rn other than mine walls, as well as mining operations and mining activities of a diverse nature, and to local variations in airflow conditions. Because of this, J obtained by the 2PM method represents an 'apparent' flux density. Significant differences were found in the flux density calculated according to different mine models. In addition, J measurements using the flux 'can' method were also carried out in mine walls and compared with the values obtained by the 2PM method. Wide discrepancies between the two methods were found. The practical and theoretical difficulties in determining J are discussed

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.

Corporate social responsibility in the mining industry: Criteria and indicators

International Nuclear Information System (INIS)

Vintro, Carla; Comajuncosa, Josep

2010-01-01

Corporate Social Responsibility (CSR) includes economic, social and environmental aspects, and it has particular significance in mining. This paper explores the subject of CSR in the mining industry and the main synergies between CSR and environmental, safety and quality management systems, whose adoption has increased during recent decades. It proposes the establishment of a set of criteria for sustainability, ethics and human capital (to be called CSR criteria). Whilst various international bodies have proposed CSR guides and indicators (commonly used as references for Stock Market investments), there is evidence that the size of the company can act as a moderator factor to the adoption of those systems. The paper offers an easy-to-use CSR performance chart (composed of 31 indicators and a global index), intended as an internal measure for companies of CSR continuous improvement.

Mineral resources accounting: A technique formonitoring the Philippine mining industry for sustainable development

Science.gov (United States)

Santos, Teodoro M.; Zaratan, May L.

Mining which extracts exhaustible mineral resources has been condemned by certain sectors as promoting social inequity and underdevelopment. This is so because once a tonne of copper, say, is mined it is forever lost to the future generation. Such perception translates into policies that are usually disadvantageous or even hostile to the industry. Despite this adverse criticism, recent developments in natural resources accounting indicate that mining can truly contribute to the sustainable economic development of a society. True worth of mining in economic development can be assessed and monitored on a continuing basis through an appropriate system of natural accounts (SNA). If the industry is found deficient, such SNA can also point out how the industry can be made to constribute to sustainable growth. The prevailing SNA is criticized as having failed to capture the adverse effects on the welfare of society of producing a nonrenewable resource such as minerals. For instance, the production of copper for a particular year registers an increase in gross national product equivalent to its monetary value. However, the concomitant depletion of the country's natural wealth due to such production is nowhere recorded in the SNA. This faulty accounting gives rise to policies that result in nonsustainable economic growth. In order to address the preceding problem, this paper presents an accounting formula applicable to any nonrenewable resource whereby revenue is decomposed into income and capital components. To achieve sustainable economic growth, it states that the capital component must be invested to generate future incomes. However, investments need not be confined to the same sector. Application of the accounting scheme to the Philippine copper and gold sectors during the 1980-1990 period leads to the following conclusions: (a) by and large, gold and copper mining operations have indeed contributed positively to national income, contrary to allegations of certain

2013-07-01

A human blood biomonitoring campaign to detect the environmental exposure to metals (Cd, Cu, Cr, Mn, Pb and Zn) in 265 subjects was performed in the South-Western part of Sardinia (an Italian island) that is a particular area with a great history of coal and metal mining (Pb/Zn mainly) activities and large industrial structures (as metallurgy). Subjects living near the industrial plant area had geometric means (GM) of blood Cd (0.79 μg/l), Cu (971 μg/l), Mn (12.2 μg/l), and Pb (55.7 μg/l) significantly higher than controls (Cd, 0.47 μg/l; Cu, 900 μg/l; Mn 9.98 μg/l; Pb, 26.5 μg/l) and than people living nearby the past mining sites. Subjects living next to one dismissed mine were statistically higher in blood Cu (GM, 1,022 μg/l) and Pb (GM, 41.4 μg/l) concentrations than controls. No differences were observed in people living in the different mining sites, and this might be related to the decennial disclosure of mines and the adoption of environmental remediation programmes. Some interindividual variables influenced blood biomonitoring data, as smoke and age for Cd, gender for Cu, age, sex and alcohol for Pb, and age for Zn. Moreover, blood metal levels of the whole population were similar to reference values representative of the Sardinian population and acceptably safe according to currently available health guidelines.

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

Restoration Practices Used on Post Mining Sites and Industrial Deposits in the Czech Republic with an Example of Natural Restoration of Granodiorite Quarries and Spoil Heaps

Directory of Open Access Journals (Sweden)

Chuman Tomáš

2015-11-01

Full Text Available Mining of minerals that have significant impact on landscape and landscape functions affects 1% of the land surface worldwide. In the Czech Republic the extent of mining sites is estimated to be more than 800 km2 and according to the state legislation the land affected by mining should be reclaimed. There are several approaches to land restoration, which are shortly reviewed in this article, from pure technical approach to one adopting natural processes. The review shows increasing appeal of scientist and conservationist to use natural processes e.g. natural or directed succession as an alternative method of post-mining sites or industrial deposits restoration due to growing evidence of conservational value of such sites in human dominated landscapes. The natural processes used for land restoration are often argued to be slow therefore the rate of spontaneous vegetation succession was assessed in stone quarries and on spoil heaps using a sequence of panchromatic aerial images. The results showed that natural processes act fast and vegetation can reach 100% cover within 10-15 years in granodiorite quarries and on spoil heaps.

Synthesis report about the after-mine mission

WNA's Policy Document : sustaining global best practices in uranium, mining and processing, principles for managing radiation, health and safety, waste and the environment

International Nuclear Information System (INIS)

Saint-Pierre, S.; Waste Management and Decommissioning Working Group-WM and DW

2008-01-01

The worldwide community of uranium mining and processing recognizes that managing radiation, health and safety, waste and the environment is paramount. Such responsible management applies at all stages of planning and activities. Today we are acting to ensure that all parties directly involved in uranium mining and processing strive to achieve the highest levels of excellence in these fields. We are doing so by sustaining a strong safety culture based on a commitment to common, internationally shared principles. This paper sets out principles for the management of radiation, health and safety, waste and the environment applicable to sites throughout the world. In national and regional settings where nuclear fuel cycle activities are well developed, these principles already serve as the underpinning for 'Codes of Practice' that govern uranium mining and processing. In any given setting, a Code of Practice is needed to guide practical implementation of these principles according to the regional, national or site-specific context. These principles are published in the belief that they hold special relevance for emerging uranium producing countries that do not yet have fully developed regulations for the control of radiation, health and safety, waste and the environment associated with uranium mining and processing. The principles are equally relevant for operators, contractors, and regulators newly engaged in uranium mining and processing. Once national regulations are fully developed, they can be expected to embody these principles. Each principle affirmed here will not apply to the same extent for each party. Ultimately, the precise allocation of responsibilities must be set at the national and local levels. This document holds the status of a policy and ethical declaration by the full WNA membership, which the global nuclear industry. The principles affirmed here are supported by key relevant international organizations, including the IAEA and the global mining

An index for drought induced financial risk in the mining industry

Science.gov (United States)

Bonnafous, L.; Lall, U.; Siegel, J.

2017-02-01

Water scarcity has emerged as a potential risk for mining operations. High capital spending for desalination and water conflicts leading to asset stranding have recently occurred. Investors in mining companies are interested in the exposure to such risks across portfolios of mining assets (whether the practical at-site consequences are foregone production, higher OPEX and CAPEX and ensuing lost revenues, or asset-stranding). In this paper, an index of the potential financial exposure of a portfolio is developed and its application is illustrated. Since the likely loss at each mine is hard to estimate a priori, one needs a proxy for potential loss. The index considers drought duration, severity and frequency (defined by a return-level in years) at each mining asset, and provides a measure of financial exposure through weighing of production or Net Asset Value. Changes in human needs are not considered, but are relevant, and could be incorporated if global data on mine and other water use were available at the appropriate resolution. Potential for contemporaneous drought incidence across sites in a portfolio is considered specifically. Through an appropriate choice of drought thresholds, an analyst can customize a scenario to assess potential losses in production value or profits, or whether conflicts could emerge that would lead to stranded assets or capital expenditure to secure alternate water supplies. Global climate data sets that allow a customized development of such an index are identified, and selected mining company portfolios are scored as to the risk associated with one publicly available drought index.

1998-01-01

The environmental impact of mining and evolving environmental legislation has been receiving increased attention worldwide in the last two decades. The potential impacts associated with unstable spoil dumps from mine operations is the focus of concern both by the mining industry, environmental legislative agencies and members of the public. Engineered slopes of mine spoils may be stable at the end of construction, but they can deteriorate over time. There is thus the need to increase the base of knowledge on the existing practices of spoil dump design and rehabilitation. Information concluded from the analysis of the industrial survey carried out on Australian spoil dump management practices at coal, gold and ore mines are presented in this paper. The questionnaire asked for details of soil type of spoils, and factors influencing the design of spoil dumps (climate, rate of erosion, height of dumps, slope gradient and length, overburden handling equipment, soil characteristics, legislation and wastes). 10 refs., 5 figs., 5 tabs

Summing up the contents of papers and discussions of the January 1993 meeting in Bochum, which gathered about 130 experts from politics, industry, science, the mining industry, the judiciasy, and the ministerial level of public administration, it can be stated that there is general approval among the experts of the new line of orientation given by the recent court rulings, towards a reassessment of the relationship between the mining industry and surface land ownership, strengthening the protection of third parties. This new approach having been readily adopted in practice, there already are many contracts reflecting the change in the mining industry's conception of itself, and experts wellcomed the turn away from the principle of 'tolerate and liquidate'.

FIBROUS MONOLITH WEAR RESISTANT COMPONENTS FOR THE MINING INDUSTRY

Energy Technology Data Exchange (ETDEWEB)

Kenneth L. Knittel

2005-05-09

The work performed on this program was to develop wear resistant, tough FM composite materials with efforts focused on WC-Co based FM systems. The materials were developed for use in mining industry wear applications. Components of interest were drill bit inserts for drilling blast holes. Other component applications investigated included wear plates for a variety of equipment such as pit shovels, wear surfaces for conveyors, milling media for ball milling operations, hydrocyclone cones, grader blades and dozer teeth. Cross-cutting technologies investigated included hot metal extrusion dies, drill bits for circuit board fabrication, cutting tools for cast iron and aluminum machining. An important part of the work was identification of the standard materials used in drilling applications. A materials trade study to determine those metals and ceramics used for mining applications provided guidance for the most important materials to be investigated. WC-Co and diamond combinations were shown to have the most desirable properties. Other considerations such as fabrication technique and the ability to consolidate shifted the focus away from diamond materials and toward WC-Co. Cooperating partners such as Kennametal and Kyocera assisted with supplies, evaluations of material systems, fabricated parts and suggestions for cross-cutting technology applications for FM architectures. Kennametal provided the raw materials (WC-Co and Al-TiCN powders) for the extent of the material evaluations. Kyocera shared their research into various FM systems and provided laboratory testing of fabricated materials. Kyocera also continued research of the FM systems with the intention of developing commercial markets for a variety of applications. The continued development of FM technology by Kyocera is seen as a direct result of the cooperation established under this funding. Kyocera has a specific interest in the commercial development of the FM technology and have licensed it and have paid

Intensifying waste water clarification in heavy and mining industries for sanitation of rivers in the Katowice district

Paluch, J.; Twardowska, I.

1976-01-01

This article presents a detailed account of the state of water pollution in the main and tributary rivers of the heavily populated and industrialized district of Katowice, Poland: Results of surveys in the years 1969 to 1972 are given. Several tables and maps show the degree of water pollution in rivers, the amount to which the values exceed pollution standards, percentage of treated and untreated industrial waste water entering the rivers, the classification of river sections according to their content of suspensions, phenols and salt. Further figures show the effectiveness of water cleaning flocculating agents and of waste water treatment at coking plants. Black coal mining and processing contributes the greater part to pollution of the rivers. Only 54% of mining industry waste water is cleaned mechanically and 3% chemically. The amount of 3,300 t/d of chlorite and sulfate salts is led into the rivers primarily from the Rybnik coal mining area. The clarification of waste water resulting from hydraulic stowing and from flotation processes is described as most problematic. Research efforts are being made at economic desalination and suspension flocculation. In the coking industry waste water is treated in 88% of the plants, but dephenolization takes place in only 50% of the plants. (29 refs.) (In German)

Kemerovo region (otherwise called Kuzbass) is the most industrially developed and urbanized region of Siberia, Russia. The main industrial branch of Kuzbass is coal output. Open pits and underground mines of Kuzbass produce about 40% of total amount of coal in Russia and more than 70% of coking coal. In the current process of the coal industry's restructuring, the closing of many unprofitable coal enterprises is associated with radical changes in their influence on the environment. The task to provide a probable forecast of ecological consequence of mine closure is both practically significant and complicated. In order to find some scientific approach to solve named problem the authors made in the paper the first attempts to analyze of accessible closed mines data in Kuzbass, to classify coal mines (working and closed) with respect to there negative influence on soil, water and atmosphere and to obtain some numerical estimates of possible bounds of this influence. 7 refs

2015-01-01

Industrial and mining activities are recognized as major sources of soil pollution. This study proposes an index system for evaluating the inherent risk level of polluting factories and introduces an integrated risk assessment method based on human health risk. As a case study, the health risk, polluting factories and integrated risks were analyzed in a typical industrial and mining gathering area in China, namely, Binhai New Area. The spatial distribution of the risk level was determined using a Geographic Information System. The results confirmed the following: (1) Human health risk in the study area is moderate to extreme, with heavy metals posing the greatest threat; (2) Polluting factories pose a moderate to extreme inherent risk in the study area. Such factories are concentrated in industrial and urban areas, but are irregularly distributed and also occupy agricultural land, showing a lack of proper planning and management; (3) The integrated risks of soil are moderate to high in the study area.

Effect of the mining industry on the formation of regions based on the example of tentative concepts of Lyublinskiy coal basin

Energy Technology Data Exchange (ETDEWEB)

Pazdziora, J

1977-01-01

It has been noted that large industrial centers and population centers often arise in areas where there are valuable mineral deposits. The role of the mining industry as a factor in the formation of industrial regions grew rapidly during the industrial revolution, when coal replaced wood as a source of energy. Gigantic industrial-urban settlements grew up in the area of coal basins in an uncontrolled manner with chaotic disruption, so that at the present time their further development and modernization is quite difficult. The complex of factors in the formation of modern coal basins was taken into consideration in draft concepts in building the central region of the Lyublinskiy coal basin. Specific mining and geological conditions of the basin, as well as the nature of the region which was non-industrial until recently are included. It makes it possible to develop a modern model of the mining surface which differs from former ones because it has a technical and social-municipal infrastructure which is rational from the organizational and engineering standpoint and has a favorable effect on the environment.

The hazards associated with uranium mining are outlined. The extent to which the law has provided for the protection of Australian uranium mine and mill workers from avoidable injury is examined. The single most significant step taken towards adequate protection of workers from the dangers of excessive exposure to ionising radiation was the approval of the Code of Practice on Radiation Protection in the Mining and Milling of Radioactive Ores (1980). The extent to which existing compensatory mechanisms, both common law and statutory, provide for the compensation of uranium mine and mill workers who sustain diseases peculiar to their employment is also examined. The capacity of the law to deal with cancers and other diseases of long latency periods is discussed

Data preprocessing in data mining

2015-01-01

Data Preprocessing for Data Mining addresses one of the most important issues within the well-known Knowledge Discovery from Data process. Data directly taken from the source will likely have inconsistencies, errors or most importantly, it is not ready to be considered for a data mining process. Furthermore, the increasing amount of data in recent science, industry and business applications, calls to the requirement of more complex tools to analyze it. Thanks to data preprocessing, it is possible to convert the impossible into possible, adapting the data to fulfill the input demands of each data mining algorithm. Data preprocessing includes the data reduction techniques, which aim at reducing the complexity of the data, detecting or removing irrelevant and noisy elements from the data. This book is intended to review the tasks that fill the gap between the data acquisition from the source and the data mining process. A comprehensive look from a practical point of view, including basic concepts and surveying t...

The objectives of these investigations completed on workplaces in the Hungarian mining industry were to characterize the physiological strain of workers by means of work pulse and to examine the effects of work-related psychological factors. Continuous heart rate (HR) recording was completed on 71 miners over a total of 794 shifts between 1987 and 1992 in mining plants of the Hungarian mining industry using a 6-channel recorder - Bioport (ZAK, Germany). The work processes were simultaneously documented by video recording along with drawing up the traditional ergonomic workday schedule. All workers passed health evaluation for fitness for work. The effects of different psychological factors (simulated danger, "instrument stress," presence of managers, and effect of prior involvement in accidents as well as different mining technologies and work place illumination) on the work pulse were evaluated. The statistical analysis was completed using SPSS software (version 13.0, SPSS Inc., USA). The work-related physiological strain differed between work places with different mining technologies in groups of 12-18 workers. The work pulse was lowest in bauxite mining (ΔHR = 22±8.9 bpm) and highest in drift drilling in dead rock with electric drilling machine (ΔHR = 30±6.9 bpm). During sham alarm situation the work pulse was significantly higher than during normal activities with the same physical task (ΔHR = 36.7±4.8 bpm vs. 25.8±1.6 bpm, p < 0.001). When work was performed under different psychological stress, the work pulse was consistently higher, while improving the work place illumination decreased the physiological strain appreciably (ΔHR (median, 25-75 percentiles) = 23, 20-26 bmp vs. 28, 25-31.3 bpm, p < 0.001). Recording the heart rate during whole-shift work along with the work conditions gives reliable results and helps isolating factors that contribute to increased strain. The results can be used to implement preventive and health promotion measures. This

Uranium mining: industry performance will continue to be driven by trends in the output and price or uranium

International Nuclear Information System (INIS)

2006-01-01

Industry revenue, which rose very strongly in the mid 2000s on the back of higher prices and higher production, is expected to retreat during the outlook i period. Indications are that a small gain in real industry revenue will be made in 2007-08, reflecting slightly higher output and some- what higher Australian dollar contract prices. However, real industry revenue is then expected to fall over the remaining years of the out- , look period, as output and exports edge lower and prices ease. Production from Ranger is expected to ease as mining winds down and the operation becomes ore processing only, and no new mines or mine expansions will come on stream over this relatively short period. Large increases in spot uranium prices in the mid 2000s were driven by falling uranium stocks, increased concern over future uranium supplies and growing speculative demand for uranium. Despite very large price rises, world uranium production responded only slowly, reflect-ing the long lead-time required to either expand existing operations or bring new developments on stream

AN ANALYSIS OF MAINTENANCE PERFORMANCE SYSTEMS IN THE SOUTH AFRICAN MINING INDUSTRY

Directory of Open Access Journals (Sweden)

Kotze, R. L. M.

2012-11-01

Full Text Available The measurement of performance is an essential part of the management process. The planning function usually defines the goals and objectives for the business enterprise or division of the enterprise. The control function should monitor the performance measures and establish corrective action if actual performance deviates significantly from planned performance. Maintenance performance measurement is therefore essential to ensure that maintenance objectives are achieved, and that maintenance adds value for the company. The objective of this paper is to discuss the findings of a project that investigated aspects of the maintenance performance system of a number of mining companies in South Africa. The findings of a survey indicated that maintenance performance management is not yet used to its full potential in the mining industry.

In a community in northern Chile, explosive procedures are used by two local industrial mines (gold, copper). We hypothesized that the prevalence of asthma and rhinoconjunctivitis in the community may be associated with air pollution emissions generated by the mines. A cross-sectional study of 288 children (aged 6-15 years) was conducted in a community in northern Chile using a validated questionnaire in 2009. The proximity between each child's place of residence and the mines was assessed as indicator of exposure to mining related air pollutants. Logistic regression, semiparametric models and spatial Bayesian models with a parametric form for distance were used to calculate odds ratios and 95 % confidence intervals. The prevalence of asthma and rhinoconjunctivitis was 24 and 34 %, respectively. For rhinoconjunctivitis, the odds ratio for average distance between both mines and child's residence was 1.72 (95 % confidence interval 1.00, 3.04). The spatial Bayesian models suggested a considerable increase in the risk for respiratory diseases closer to the mines, and only beyond a minimum distance of more than 1800 m the health impact was considered to be negligible. The findings indicate that air pollution emissions related to industrial gold or copper mines mainly occurring in rural Chilean communities might increase the risk of respiratory diseases in children.

2014-11-01

To evaluate the mortality experience of Minnesota taconite mining industry workers. Mortality was evaluated between 1960 and 2010 in a cohort of Minnesota taconite mining workers employed by any of the seven companies in operation in 1983. Standardised mortality ratios (SMR) were estimated by comparing observed deaths in the cohort with expected frequencies in the Minnesota population. Standardised rate ratios (SRR) were estimated using an internal analysis to compare mortality by employment duration. The cohort included 31,067 workers with at least 1 year of documented employment. Among those, there were 9094 deaths, of which 949 were from lung cancer, and 30 from mesothelioma. Mortality from all causes was greater than expected in the Minnesota population (SMR=1.04, 95% CI 1.02 to 1.04). Mortality from lung cancer and mesothelioma was higher than expected with SMRs of 1.16 for lung cancer (95% CI 1.09 to 1.23) and 2.77 for mesothelioma (95% CI 1.87 to 3.96). Other elevated SMRs included those for cardiovascular disease (SMR=1.10, 95% CI 1.06 to 1.14), specifically for hypertensive heart disease (SMR=1.81, 95% CI 1.39 to 2.33) and ischemic heart disease (SMR=1.11, 95% CI 1.07 to 1.16). Results of the SRR analysis did not show variation in risk by duration of employment. This study provides evidence that taconite workers may be at increased risk for mortality from lung cancer, mesothelioma, and some cardiovascular disease. Occupational exposures during taconite mining operations may be associated with these increased risks, but non-occupational exposures may also be important contributors.

Volume No. 8 of the series of papers quantifies the system of aims, i.e. it defines synthetic data of laws and regulations of mining of DIN standards, and VDI guidelines, of generally accepted rules of engineering as well as of certified findings of industrial science as minimum requirements. This definition is followed by the examination of the type of medium-term development to be expected in the bituminous coal mining industry of the Ruhrkohle AG up to the year 1985. Then the general aims 1 and 2 given in volume No. 7 are described in detail. These descriptions constitute an excellent summary of the present state of knowledge concerning the improvement of working conditions in the bituminous coal mining industry. Finally, a study on the transferability of research findings is given. One statement is of special importance, i.e., that transferability is not characterized by technological feasibility alone which depends to a high degree on marginal, organizational conditions within the company, e.g., on the information system, on its hierarchical structure, on the company's policy, and on departamental policy. In this study, only the technological transferability is examined. To enable us to assess it, appropriate statements are made in a brief description of the research project carried out since 1974, which was sponsored within the action programme ''Humanization of Industrial Life''.

Code of practice in industrial radiography

International Nuclear Information System (INIS)

Karma, S. E. M.

2010-12-01

The aim of this research is to developing a draft for a new radiation protection code of practice in industrial radiography without ignoring that one issued in 1998 and meet the current international recommendation. Another aim of this study was to assess the current situation of radiation protection in some of the industrial radiography department in Sudan. To achieve the aims of this study, a draft of a code of practice has been developed which is based on international and local relevant recommendations. The developed code includes the following main issues: regulatory responsibilities, radiation protection program and design of radiation installation. The practical part of this study includes scientific visits to two of industrial radiography departments in Sudan so as to assess the degree of compliance of that department with what state in the developed code. The result of each scientific visits revealed that most of the department do not have an effective radiation protection program and that could lead to exposure workers and public to unnecessary dose. Some recommendations were stated that, if implemented could improve the status of radiation protection in industrial radiography department. (Author)

Recent developments in Australia's uranium mining industry

International Nuclear Information System (INIS)

McKay, A.D.

2001-01-01

Uranium is produced at two mining/milling operations in Australia - Ranger in the Alligator Rivers Region of the Northern Territory, and Olympic Dam in South Australia. In 1996, Ranger produced 4138 tonnes (t) U 3 O 8 from stockpiled ore mined from Ranger No. 1 Orebody. The capacity of the Ranger mill is being expanded to 5000 tonnes per annum (tpa) U 3 O 8 to coincide with the commencement of mining from No. 3 Orebody in mid-1997. The Olympic Dam copper-uranium-gold-silver deposit is the world's largest deposit of low cost uranium. The operation currently has an annual production of 85,000 t copper, 1700 t U 3 O 8 and associated gold and silver. WMC Ltd proposes to expand annual production to 200 000 t copper and approximately 4600 t U 3 O 8 by end of 1999. The environmental impact of the expansion is being assessed jointly by both Commonwealth and South Australian Governments. A draft Environmental Impact Statement (EIS) was released in May. Since its election in March 1996, the Liberal/National Party Coalition Government has made a number of changes to the Commonwealth Government's policies relating to uranium mining, including removal of the former Government's 'three mines' policy, and relaxation of the guidelines for foreign investment in Australian uranium mines. These changes, together with an improved outlook for the uranium market, have resulted in proposals to develop new mines at Jabiluka (Northern Territory), Kintyre (Western Australia) and Beverley (South Australia). Energy Resources of Australia Ltd proposes to develop an underground mine at Jabiluka with the ore to be processed at Ranger mill. Initial production will be 1800 tpa U 3 O 8 which will increase to 4000 tpa U 3 O 8 by the 14th year. The draft EIS was released for public comment in October 1996, and the final EIS is to be released in June 1997. Canning Resources Ltd proposes to mine the Kintyre deposit by open cut methods commencing in 1999 with an annual production of 1200 tpa U 3 O 8

Environmental noise management in the area of opencast mines

Directory of Open Access Journals (Sweden)

Lilić Nikola

2017-01-01

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.

The Exclusive Economic Zone (EEZ) declared by President Reagan in March 1983 has met with a mixed response from those who would benefit from a guaranteed, 200-nautical-mile (370-km) protected underwater mining zone off the coasts of the United States and its possessions. On the one hand, the U.S. Department of the Interior is looking ahead and has been very successful in safeguarding important natural resources that will be needed in the coming decades. On the other hand, the mining industry is faced with a depressed metals and mining market.A report of the Exclusive Economic Zone Symposium held in November 1983 by the U.S. Geological Survey, the Mineral Management Service, and the Bureau of Mines described the mixed response as: “ … The Department of Interior … raring to go into promotion of deep-seal mining but industrial consortia being very pessimistic about the program, at least for the next 30 or so years.” (Chemical & Engineering News, February 5, 1983).

Uranium mining: present indian scenario and future trends

International Nuclear Information System (INIS)

Gupta, Ramendra; Acharya, D.

2003-01-01

Mining industry has long been considered a high risk investment, tied down with long gestation periods. Large manpower deployment as also health and safety are other concerns associated with mining. Greater focus on sustainable development has seen metal prices falling worldwide. This has been largely due to greater recycling as well as development of alternate manmade material. Growing social concerns of the working environment as well as the impact of mining activity on ecology in its neighborhood are other areas drawing attention of the mining community. Uranium mining shares all these concerns besides issues related to its radioactive aspects. Technology continues to evolve in order to meet these challenges and make mining an attractive investment destination. Development of cleaner fuels, greater use of hydraulic power, microprocessor based fuel injection systems, flow of information, its efficient processing and a host of technology enabled systems are driving this evolution. These have influenced the entire gamut of mining activities from mine entries, mine layouts, mining methods to rock breakage and hoisting. Social concerns have prompted mine closure and related costs being factored in, at the mine opening stage itself. This paper describes some of these evolutions in India while looking at the emerging technologies and practices worldwide. (author)

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

Directory of Open Access Journals (Sweden)

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.

In the highway area there was found the worsening living conditions of thallus at the lichens Physcia, manifested in the reduction of a projective cover and reducing of the size of thallus with the increasing of the degree of their damage. It is set that specific composition and conformities to law of distribution of cladinas is determined the type of the industrial loading. Predominance at the lichens of crustaceous cladinas, insignificant participation of fissile cladinas and complete absence of bushy forms is the possible consequence of industrial influence. We registered some 3 species of epiphytic lichens, namely Phaeophyscia nigricans, Physcia tenella, Physcia adscendens in a residential zone, while on conditional control area we found Physcia orbicularis. The dominant species was scum-like shape Phaeophyscia nigricans, Physcia adscendens, Physcia tenella, while on conditional control region we marked predominance of Physcia orbicularis and did not registered bushy lichens form. We also divided the lichens into two groups according to the resistance towards air pollution - moderate (2 species, Phaeophyscia nigricans, Physcia tenella and toxic-resistant (2 species, Physcia orbicularis, Physcia adscendens. Epiphytic lichens in terms of residential areas compared to conventionally control area characterized by a decrease of morphometric parameters of the melt. Key results can be used to predict the state of ecosystems using lichenoindication in terms of industrial regions of Ukraine.

Radiation protection in uranium mining and milling industry

International Nuclear Information System (INIS)

Raghavayya, M.

2005-01-01

The first phase of the Nuclear Fuel Cycle is exploration for uranium and the next is mining and milling of uranium ore. This phase is mostly characterised by low levels of radioactivity and radiation exposure of the workers involved. Yet it is a paradoxical truth that incidence of cancer among the work force, especially miners, due to occupational radiation exposure (from radon and decay products) has been proved only in uranium mines in the entire Nuclear Fuel Cycle. Of course such incidence occurred before the detrimental effect of radiation exposure was realised and understood. Therefore it is important to familiarise oneself with the radiation hazards prevalent in the uranium mining and milling facilities so as to take appropriate remedial measures for the protection of not only the workers but also the public at large. There are both open cast and underground uranium mines around the world. Radiation hazards are considerably less significant in open cast mines than in underground mines unless the ore grade is very high. By default therefore the discussion which ensues relates mainly to radiation hazards in underground uranium mines and associated milling operations. The discussion gives a brief outline of typical uranium mine and mining and milling operations. This is followed by a description of the radiation hazards therein and protection measures that are to be taken to minimise radiation exposure. (author)

Benchmarking Sustainability Practices Use throughout Industrial Construction Project Delivery

Directory of Open Access Journals (Sweden)

Sungmin Yun

2017-06-01

Full Text Available Despite the efforts for sustainability studies in building and infrastructure construction, the sustainability issues in industrial construction remain understudied. Further, few studies evaluate sustainability and benchmark sustainability issues in industrial construction from a management perspective. This study presents a phase-based benchmarking framework for evaluating sustainability practices use focusing on industrial facilities project. Based on the framework, this study quantifies and assesses sustainability practices use, and further sorts the results by project phase and major project characteristics, including project type, project nature, and project delivery method. The results show that sustainability practices were implemented higher in the construction and startup phases relative to other phases, with a very broad range. An assessment by project type and project nature showed significant differences in sustainability practices use, but no significant difference in practices use by project delivery method. This study contributes to providing a benchmarking method for sustainability practices in industrial facilities projects at the project phase level. This study also discusses and provides an application of phase-based benchmarking for sustainability in industrial construction.

Coal accounts for approximately 41% of the world's electricity generation. Demand for thermal coal is influenced by factors that include availability, prices of competing products such as oil, gas and nuclear power, and the demand for electricity. The aim of this article is to provide an exposition of supply chain dynamics within the South African coal mining industry and to argue for a more efficient and collaborative supply chain. The authors attempt to investigate at local and global level, the current trends pertaining to the level of reserves, production and consumption of coal. The article further demonstrates the shortcomings of current logistics in meeting the demand for coal in both domestic and export markets. The article draws from secondary data sourced from academic papers, government and agency documents in the exposition of the coal mining supply chain. The paper concludes by recommending the need for a scientific study on supply chain constraints facing the coal mining industry in South Africa.

Case studies of sealing methods and materials used in the salt and potash mining industries

1995-11-01

Sealing methods and materials currently used in salt and potash industries were surveyed to determine if systems analogous to the shaft seal design proposed for the Waste Isolation Pilot Plant (WIPP) exist. Emphasis was first given to concrete and then expanded to include other materials. Representative case studies could provide useful design, construction, and performance information for development of the WIPP shaft seal system design. This report contains a summary of engineering and construction details of various sealing methods used by mining industries for bulkheads and shaft liners. Industrial experience, as determined from site visits and literature reviews, provides few examples of bulkheads built in salt and potash mines for control of water. Sealing experiences representing site-specific conditions often have little engineering design to back up the methods employed and even less quantitative evaluation of seal performance. Cases examined include successes and failures, and both contribute to a database of experiences. Mass salt-saturated concrete placement under ground was accomplished under several varied conditions. Information derived from this database has been used to assess the performance of concrete as a seal material. Concrete appears to be a robust material with successes in several case studies. 42 refs

European sites contaminated by residues from the ore extracting and processing industries

International Nuclear Information System (INIS)

Vandenhove, H.

2000-01-01

Activities linked with the ore extraction and processing industries may lead to enhanced levels of naturally occurring radionuclides (NORs) in products, by-products and waste and at the installations and in the surroundings of the facility. In the framework of the EC-DGXI CARE project (Common Approach for REstoration of contaminated sites) nine important categories of industries were identified and discussions were summarized on the industrial processes and the levels of NORs in parent material, waste and by-products. The most contaminating industries are uranium mining and milling, metal mining and smelting and the phosphate industry. Radionuclide levels in products and/or waste products from the oil and gas extraction industry and of the rare earth, zirconium and ceramics industries may be particularly elevated, but waste streams are limited. The impact on the public from coal mining and power production from coal is commonly considered low. No typical values are available for contaminant levels in materials, buildings and surroundings of radium extraction and luminizing plants, nor for thorium extraction and processing plants. An attempt to give an overview of sites in Europe contaminated with NORs, with emphasis on past practices, was only partly successful since information was often limited or unavailable. The most prominent case of environmental contamination due to mining and processing activities (uranium, metal and coal mining) is in eastern Germany. (author)

Tinto and Odiel rivers (SW of Spain) is an ecosystem of great interest that is seriously affected by acid mine drainage (AMD) from long-term mining activities (pH < 3). Additionally, a large industrial complex is located in the surroundings of this estuary and Huelva town, which includes two phosphate rock processing plants that produce about 3 millions of tons per year of a byproduct called phosphogypsum (PG) containing high U-series radionuclides concentrations. For these reasons, the estuary of Huelva is one of the most heavy metals and radionuclides polluted estuarine systems in Europe with extremely low pH.

Environmental management plan of the mining and industrial uranium complex in Brazil

International Nuclear Information System (INIS)

Figuereido, N.; Hilton, M.; Wiikman, L.; Oliveira, M.; Taddei, J.

1996-01-01

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.

Management of the environment in the uranium mining industry has an eventful history of more than 50 years. In addition to examples of successful restoration of mining and preparation sites in some countries there are also numerous cases, in which no or defective restoration left behind serious waste deposits. In the course of the renaissance of the uranium industry there is increasing interest in the rehabilitation of such waste sites. There is still an urgent requirement to eradicate the environmental effects of the old mining industry. Previous deposits could be of interest for renewed working under the present economic boundary conditions. Restoration as an integral part of the current and future uranium mining industry with the application of modern international safety standards is extremely important. The contribution provides a survey of restoration projects of the old mining industry in various parts of the world and shows how the International Atomic Energy Agency, the national supervisory and approval authorities as well as the mining companies collaborate closely at many sites on solution of the difficult problems.

No nuclear mining industries and the increase to natural radiation exposure

International Nuclear Information System (INIS)

Pires do Rio, Monica Aquino

1999-01-01

Mining and processing activities dealing with mineral ores containing associated uranium and thorium series elements can make these radionuclides available in their products, byproducts and in the environment, leading to the enhancement of the exposure of the public to natural radiation. In the present study, niobium, phosphate, coal and gold mining plants have been selected as case studies, aiming to identify possible radiological impact sources during and after ceasing the operation on these units. In order to achieve that, the radiological characterization of samples from ore processing, drainage water and other liquid emissions was carried out. The potential environmental radiological impact was quantified by means of estimating the effective dose equivalent, H E , for present and future scenarios considering the use of the environment in the vicinities of the units and future tailing storage sites. The results confirm these mining industries as activities potentially enhancing exposure to natural radiation. The possible use of solid wastes, abandoned at the end of operation, represents a long term radiological concern. The acid drainage, as well as the chemical processing of mineral ores constitute relevant impact factors for present and future scenarios. Thus, the legislation for environmental licensing must be reviewed in order to take into account the potential environmental radiological impact caused by these units, as well as the establishment of remediation procedures for waste storage areas in the existing sites.

Radon exposure in uranium mining industry vs. exposure in tourist caves

International Nuclear Information System (INIS)

Quindos Poncela, L.; Fernandez Navarro, P.; Sainz Fernandez, C.; Gomez Arozamena, J.; Bordonoba Perez, M.

2004-01-01

There is a fairly general consensus among health physicists and radiation professionals that exposure to radon progeny is the largest and most variable contribution to the population's exposure to natural sources of radiation. However, this exposure is the subject of continuing debate concerning the validity of risk assessment and recommendations on how to act in radon-prone areas. The purpose of this contribution is to situate the radon issue in Spain in two very different settings. The first is a uranium mining industry located in Saelices el Chico (Salamanca), which is under strict control of the Spanish Nuclear Safety Council (CSN). We have measured radon concentrations in different workplaces in this mine over a five-year period. The second setting comprises four tourist caves, three of which are located in the province of Cantabria and the fourth on the Canary Island of Lanzarote. These caves are not subject to any administrative control of radiation exposure. Measured air 222 Rn concentrations were used to estimate annual effective doses due to radon inhalation in the two settings, and dose values were found to be from 2 to 10 times lower in the uranium mine than in the tourist caves. These results were analysed in the context of the new European Basic Safety Standards Directive (EU-BSS, 1996). (authors)

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)

Lime in gold and uranium mining

International Nuclear Information System (INIS)

Van Staden, C.M.

1979-01-01

In this article the author discusses the role of lime in gold and uranium extraction and looks more closely at the industry's efforts to improve the environment by vegetation of sand dumps and slimes dams. He then comes to the conclusion that lime has been and still is the most effective, practical and cheapest chemical that can be used in the South African gold and uranium mining industry to settle pulps, protect cyanide solutions, aid the vegetation of dumps and neutralise acidic waters and residues. The gold and uranium industry is very pollution concious, and in South Africa the importance of the role that lime plays in combating air and water pollution cannot be over emphasised

The developments in the German coal mining industry are always associated with the questions of national energy supply. The main emphasis is on a balanced energy mix with the aim of security of supply, compatibility with the environment and profitability. The operating aim of an increase in productivity to reduce costs is derived on this basis. The innovative operation required for this purpose results from the combination of technical, process and social innovation. The two last-mentioned are becoming increasingly important for a high rate of innovation at the collieries of DSK. (orig.)

Socially Responsible Mining: the Relationship between Mining and Poverty, Human Health and the Environment

Science.gov (United States)

Maier, Raina M.; Díaz-Barriga, Fernando; Field, James A.; Hopkins, James; Klein, Bern; Poulton, Mary M.

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.

The information contained in the National Radiological Protection Board's report (Strong, J.C., Laidlaw, A.J. and O'Riordan, M.C., Radon and its daughters in various British mines, NRPB-R39 (1975), HMSO) is updated with data collected between October 1975 and January 1976, and certain aspects of the work highlighted. The latest results in the continuing survey, which now covers more than 60 non-coal mines employing nearly 2000 men underground, reflect the corrective actions taken in a number of mines by improvements in ventilation management. The survey is now carried out by means of radon flasks supplied by post and returned to the NRPB for measurement. An empirical relationship is used to relate the radon gas and daughter concentrations at different ventilation rates. The results show that there has been a marked decrease (from 42% to 24%) in the number of men exposed above 4 working level months (WLM) in a year, the category requiring supervision (1 to 4 WLM in a year) has increased from 15% to 28%, and the lowest exposure category has increased from 43% to 48%. Although excessive exposures are still a problem, particularly in some tin mines in Cornwall, general compliance with the exposure limit seems possible in the near future. (U.K.)

FIBROUS MONOLITH WEAR RESISTANT COMPONENTS FOR THE MINING INDUSTRY

Energy Technology Data Exchange (ETDEWEB)

Mike L. Fulcher; Kenneth L. Knittel

2004-06-08

The work performed on this program was to develop wear resistant, tough FM composite materials with efforts focused on WC-Co based FM systems. The materials were developed for use in mining industry wear applications. Components of interest were drill bit inserts for drilling blast holes. Other component applications investigated included wear plates for a variety of equipment such as pit shovels, wear surfaces for conveyors, milling media for ball milling operations, hydrocyclone cones, grader blades and dozer teeth. Cross-cutting technologies investigated included hot metal extrusion dies, drill bits for circuit board fabrication, cutting tools for cast iron and aluminum machining. An important part of the work was identification of the standard materials used in drilling applications. A materials trade study to determine those metals and ceramics used for mining applications provided guidance for the most important materials to be investigated. WC-Co and diamond combinations were shown to have the most desirable properties. Other considerations such as fabrication technique and the ability to consolidate shifted the focus away from diamond materials and toward WC-Co. Cooperating partners such as Kennametal and Kyocera assisted with supplies, evaluations of material systems, fabricated parts and suggestions for cross-cutting technology applications for FM architectures. Kennametal provided the raw materials (WC-Co and Al-TiCN powders) for the extent of the material evaluations. Kyocera shared their research into various FM systems and provided laboratory testing of fabricated materials. Field testing provided by partners Superior Rock Bit and Brady Mining and Construction provided insight into the performance of the fabricated materials under actual operational conditions. Additional field testing of cross-cutting technology, the extrusion of hot metals, at Extruded Metals showed the potential for additional market development.

Australian government policy is explained in terms of adherence to the Non-Proliferation Treaty. Two alleged uncertainties are discussed: the future of Australian mining industry as a whole -on which it is said that Australian uranium mines will continue to be developed; and detailed commercial policy of the Australian government - on which it is suggested that the three-mines policy of limited expansion of the industry would continue. Various aspects of policy, applying the principles of the NPT, are listed. (U.K.)

Occupational respiratory diseases in the South African mining industry.

Science.gov (United States)

Nelson, Gill

2013-01-24

Crystalline silica and asbestos are common minerals that occur throughout South Africa, exposure to either causes respiratory disease. Most studies on silicosis in South Africa have been cross-sectional and long-term trends have not been reported. Although much research has been conducted on the health effects of silica dust and asbestos fibre in the gold-mining and asbestos-mining sectors, little is known about their health effects in other mining sectors. The aims of this thesis were to describe silicosis trends in gold miners over three decades, and to explore the potential for diamond mine workers to develop asbestos-related diseases and platinum mine workers to develop silicosis. Mine workers for the three sub-studies were identified from a mine worker autopsy database at the National Institute for Occupational Health. From 1975 to 2007, the proportions of white and black gold mine workers with silicosis increased from 18 to 22% and from 3 to 32% respectively. Cases of diamond and platinum mine workers with asbestos-related diseases and silicosis, respectively, were also identified. The trends in silicosis in gold miners at autopsy clearly demonstrate the failure of the gold mines to adequately control dust and prevent occupational respiratory disease. The two case series of diamond and platinum mine workers contribute to the evidence for the risk of asbestos-related diseases in diamond mine workers and silicosis in platinum mine workers, respectively. The absence of reliable environmental dust measurements and incomplete work history records impedes occupational health research in South Africa because it is difficult to identify and/or validate sources of dust exposure that may be associated with occupational respiratory disease.

The amount of data getting generated in any sector at present is enormous. The information flow in the pharma industry is huge. Pharma firms are progressing into increased technology-enabled products and services. Data mining, which is knowledge discovery from large sets of data, helps pharma firms to discover patterns in improving the quality of drug discovery and delivery methods. The paper aims to present how data mining is useful in the pharma industry, how its techniques can yield good results in pharma sector, and to show how data mining can really enhance in making decisions using pharmaceutical data. This conceptual paper is written based on secondary study, research and observations from magazines, reports and notes. The author has listed the types of patterns that can be discovered using data mining in pharma data. The paper shows how data mining is useful in the pharma industry and how its techniques can yield good results in pharma sector. Although much work can be produced for discovering knowledge in pharma data using data mining, the paper is limited to conceptualizing the ideas and view points at this stage; future work may include applying data mining techniques to pharma data based on primary research using the available, famous significant data mining tools. Research papers and conceptual papers related to data mining in Pharma industry are rare; this is the motivation for the paper.

Mining industry enters a new era of AIDS prevention. Eye witness: South Africa.

Science.gov (United States)

Heywood, M

1996-06-01

Miners in South Africa are now more at risk of contracting human immunodeficiency virus (HIV) than of being in a mining accident. Some epidemiologists predict that the mines could be experiencing 12,000-40,000 deaths related to acquired immunodeficiency syndrome (AIDS) by 2010. In 1986, HIV infection among mineworkers was 1/3500. Gencor medical personnel now estimate that 20% of the company's employees are HIV-positive and that 30 workers are dying of AIDS each month. In August 1995, the Chamber of Mines, the World Bank, and the World Health Organization (WHO) held a seminar to discuss the potential impact of the epidemic; it was followed by a workshop, "Research Needs and Priorities for the Management of HIV/AIDS Transmission in the Mining Industry," which was organized by the Epidemiology Unit in Johannesburg. Although the seminar invited no people with HIV, mineworkers, or government representatives, the workshop did; however, no representatives of the National Union of Mineworkers (NUM), or the Chamber of Mines, came. In spite of this, a new, holistic approach to HIV-prevention is emerging in the mining sector. A decade of education has not changed risk behaviors, so more emphasis will be placed on outreach programs to the communities, including the prostitutes, with which the miners interact, and on treatment of sexually transmitted diseases (STDs). The mining sector is in a unique position to fight HIV because it already has an extensive medical infrastructure with the capacity to treat STDs effectively, a unionized workforce to provide a pool of peer educators, and recruitment agencies to extend HIV-prevention into rural areas. Obstacles to effective HIV/AIDS education include discrimination (Workers are tested for HIV without consent, and dismissed, if found to be positive, regardless of union agreements.); a psychological factor that is related to underground work and produces recklessness; poor living conditions; and illiteracy. Many myths remain about

Although much research has been conducted on the health effects of silica dust and asbestos fibre in the gold-mining and asbestos-mining sectors, little is known about their health effects in other mining sectors. Objective: The aims of this thesis were to describe silicosis trends in gold miners over three decades, and to explore the potential for diamond mine workers to develop asbestos-related diseases and platinum mine workers to develop silicosis. Methods: Mine workers for the three sub-studies were identified from a mine worker autopsy database at the National Institute for Occupational Health. Results: From 1975 to 2007, the proportions of white and black gold mine workers with silicosis increased from 18 to 22% and from 3 to 32% respectively. Cases of diamond and platinum mine workers with asbestos-related diseases and silicosis, respectively, were also identified. Conclusion: The trends in silicosis in gold miners at autopsy clearly demonstrate the failure of the gold mines to adequately control dust and prevent occupational respiratory disease. The two case series of diamond and platinum mine workers contribute to the evidence for the risk of asbestos-related diseases in diamond mine workers and silicosis in platinum mine workers, respectively. The absence of reliable environmental dust measurements and incomplete work history records impedes occupational health research in South Africa because it is difficult to identify and/or validate sources of dust exposure that may be associated with occupational respiratory disease.

Blasting activity of the mining industry in the United States

About 2 megatons of chemcial explosives are used annually in the U.S., principally in mining for coal and metal ores. Most of this explosive is used in surface mines rather than underground mines. On a typical work day there are about 30 explosions greater than 50 tons, including one shot greater than 200 tons. Shots in underground mines are typically much smaller, because of safety considerations. Almost all chemical explosions above 1 ton in the U.S. are ripple-fired and almost all above 10 tons are also shallow. Almost all are intended to break rock or to remove overburden, and are therefore very inefficient, relative to contained single shots, in generating seismic signals at regional ore teleseismic distances. These attributes make explosions used in industry quite different from the Non-Proliferation Experiment. There is very little correlation between the total amount of explosive used in a ripple-fired blast, and the seismic magnitude. Statistics on blasting magnitudes are of interest in the context of monitoring network. There is a blast reported with regional (or duration) magnitude 3.5 or above, in the U.S., a few tens of times a year; but it would appear that the teleseismic magnitude (m{sub b}) of such events are significantly lower than 3.5. Only about 10 to 30 chemical explosions per year in the U.S. are detected teleseismically with m{sub b}>3. Methods of routinely discriminating most chemical explosions from other seismic sources use spectra of regional phases at frequencies up to about 30 Hz, which is significantly higher than frequencies needed for recording teleseismic signals. The best discriminants appear to be the high-frequency spectral ratio of waves with P-wave energy (e.g. Pn or Pg) to waves with S-wave energy (Sn or Lg); and the use of spectrograms, which can be particularly useful in identifying ripple-firing.

Reduction of Conflicts in Mining Development Using "Good Neighbor Agreements"

Science.gov (United States)

Masaitis, A.

2013-05-01

New environmental and social challenges for the mining industry in both developed and developing countries show the obvious need to implement "responsible" mining practices that include improved community involvement. Good Neighbor Agreements (GNA's) are a relatively new mechanism for improving communication and trust between a mining company and the community. The focus of a GNA will be to provide a written and enforceable agreement, negotiated between the concerned public and the respective mining company to respond to concerns from the public, and also provide a mechanism for conflict resolution, when there is mutual benefit to maintain a working relationship. Development of GNA's, a recently evolving process that promotes environmentally sound relationships between mines and the surrounding communities. Modify and apply the resulting GNA formulas to the developing countries and countries with transitional economies. This is particularly important for countries that have poorly functioning regulatory systems that cannot guarantee a healthy and safe environment for the communities. The fundamental questions addressed by this research. 1. This is a three-year research project started in August 2012 at the University of Nevada, Reno (UNR) to develop a Good Neighbor Agreements standards as well as to investigate the details of mine development. 2. Identify spheres of possible cooperation between mining companies, government organizations, and the Non-Governmental Organizations (NGO's). Use this cooperation to develop international standards for the GNA, to promote exchange of environmental information, and exchange of successful environmental, health, and safety practices between mining operations from different countries. Discussion: The Good Neighbor Agreement currently evolving will address the following: 1. Provide an economically viable mechanism for developing a partnership between mining operations and the local communities that will increase mining industry

Derived surface contamination limits for the uranium mining and milling industry

International Nuclear Information System (INIS)

Ching, S.H.

1984-10-01

Derived Surface Contamination Limits (DSCL) are proposed for the control of surface contamination at the work place for the uranium mining and milling industry. They have been derived by a method incorporating recent ICRP recommendations and consideration of the radiation exposure pathways of ingestion, inhalation and external irradiation of the basal layer of skin. A generalized DSCL of 10 5 Bq/m 2 of beta activity is recommended for all contaminants likely to be found in uranium mine and mill workplaces except for fresh uranium concentrates. In the latter case, the DSCL is expressed in terms of alpha activity because the ratio of beta to alpha activities for fresh uranium concentrates is variable; the beta activity increases with the ingrowth of U-238 daughter products (Th-234 and Pa-234m) until secular equilibrium is re-established in about six months. A surface contamination limit of 10 4 Bq/m 2 of beta activity is proposed for the release of non-porous materials and equipment with no detectable loose contamination to the public domain

In Greece a significant amount of mineral and ore deposits have been recorded accompanied by large industrial interest and a long mining history. Today many active and/or abandoned mine sites are scattered within the country; while mining activities take place in different sites for exploiting various deposits (clay, limestone, slate, gypsum, kaolin, mixed sulphide ores (lead, zinc, olivine, pozzolan, quartz lignite, nickel, magnesite, aluminum, bauxite, gold, marbles etc). The most prominent recent ones are: (i) the lignite exploitation that is extended in the area of Ptolemais (Western Macedonia) and Megalopolis (Central Peloponnese); and (ii) the major bauxite deposits located in central Greece within the Parnassos-Ghiona geotectonic zone and on Euboea Island. In the latter area, significant ores of magnesite were exploited and mixed sulphide ores. Centuries of intensive mining exploitation and metallurgical treatment of lead-silver deposits in Greece, have also resulted in significant abandoned sites, such as the one in Lavrion. Mining activities in Lavrio, were initiated in ancient times and continued until the 1980s, resulting in the production of significant waste stockpiles deposited in the area, crucial for the local water resources. Ιn many mining sites, environmental pressures are also recorded after the mine closure to the aquatic environment, as the surface waters flow through waste dump areas and contaminated soils. This paper aims to the geospatial visualization of the mining activities in Greece, in connection to their negative (surface- and/or ground-water pollution; overpumping due to extensive dewatering practices) or positive (enhanced groundwater recharge; pit lakes, improvement of water budget in the catchment scale) impacts on local water resources.

Full Text Available The mining industry exists because humans need mining commodities to meet their daily needs such as motor vehicles, mobile phones, electronic equipment and others. Mining commodities as mentioned in Government Regulation No. 23 of 2010 on Implementation of Mineral and Coal Mining Business Activities are radioactive minerals, metal minerals, nonmetallic minerals, rocks and coal. Mineral and coal mining is conducted to obtain the mining commodities through production operations. Mining and coal mining companies have an obligation to ensure that the mining environment in particular after the post production operation or post mining continues. The survey research aims to examine technically the post-mining plan in coal mining of PT Samantaka Batubara in Indragiri Hulu Regency of Riau Province towards the sustainability of the mining environment. The results indicate that the post-mining plan of PT Samantaka Batubara has met the technical aspects required in post mining planning for a sustainable mining environment. Postponement of post-mining land of PT Samantaka Batubara for garden and forest zone. The results of this study are expected to be useful and can be used by stakeholders, academics, researchers, practitioners and associations of mining, and the environment.

Asif, Zunaira; Chen, Zhi

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.

The majority of research about employment discrimination in the U.S. Mining, Quarrying, and Oil/Gas (MQOGE) industries has concentrated on gender and race, while little attention has focused on disability. To explore allegations of Americans with Disabilities Act (ADA) Title I discrimination made to the Equal Employment Opportunity Commission (EEOC) by individuals with disabilities against MQOGE employers. Key data available to this study included demographic characteristics of charging parties, size of employers, types of allegations, and case outcomes. Using descriptive analysis, allegation profiles were developed for MQOGE's three main sectors (i.e., Oil/Gas Extraction, Mining except Oil/Gas, and Support Activities). These three profiles where then comparatively analyzed. Lastly, regression analysis explored whether some of the available data could partially predict MQOGE case outcomes. The predominant characteristics of MQOGE allegations were found to be quite similar to the allegation profile of U.S. private-sector industry as a whole, and fairly representative of MQOGE's workforce demographics. Significant differences between MQOGE's three main sector profiles were noted on some important characteristics. Lastly, it was found that MQOGE case outcomes could be partially predicted via some of the available variables. The study's limitations were presented and recommendations were offered for further research.

Radon in uranium mining industry and application of SSNTD in monitoring and dose evaluation

International Nuclear Information System (INIS)

Khan, A.H.

2006-01-01

Radon is present everywhere and accounts for a globally major share of natural radiation exposure of the population. Though it is present in most of the underground workings it is a source of concern in uranium mining and ore processing industry as well as in many other operations carried out in confined spaces below the ground, like railway tunnels and non-uranium underground mines. Many monitoring techniques are available for evaluation of radon and its short-lived progeny concentrations. Scintillation cell techniques, also called Lucas cell, is one of the earliest developed methods of radon monitoring still widely used in mines where appreciable concentrations of radon above about 40-50 Bq.m -3 are expected. For low concentration of radon as observed in the atmosphere, dwellings and other workplaces, the radon absorption in charcoal followed by gamma counting, two filter method and electrostatic techniques are available. Solid state nuclear track detectors (SSNTD) are now widely used for a variety of situations for monitoring of low level of radon over an extended period of time. It is now extensively used in radon monitoring in dwellings and also in radon dosimetry in mines. Radon daughters being the more important contributors to the internal radiation exposure are also being monitored using conventional techniques as well as SSNTD. Various monitoring techniques for radon and its progeny and the concentrations observed at different stages of uranium mining, ore processing and tailings management are discussed in this presentation.

ENGLISH ABSTRACT: The coal mining industry faces increased pressure for higher quality coal at lower cost and increased volumes. To satisfy these requirements the industry needs technically skilled first line supervisors with operational management skills. Most first line supervisors possess the necessary technical, but not the required operational management skills. Various operational management philosophies, describing world-class operational management practices exist; however, it is not possible to implement these philosophies as-is in a mining environment due to the various differences between manufacturing and mining. The solution is to provide an operational management model, adapted from these philosophies, to first line supervisors in the coal mining industry.

AFRIKAANSE OPSOMMING: Die steenkoolmynbedryf ervaar groeiende druk van die mark vir hoër gehalte steenkool, laer koste en verhoogde volumes. Om hierdie behoefte te bevredig benodig die myn tegniesgeskoolde eerstelyntoesighouers met bedryfsbestuursvaardighede. Ongelukkig beskik die meeste toesighouers wel oor die nodige tegniese kennis, maar nie die nodige bedryfsbestuursvaardighede nie. Daar bestaan verskeie bedryfsbestuursfilosofieë wat wêreldklas bedryfsbestuurspraktyke omskryf. Dit is egter nie moontlik om die filisofieë net so in die mynbedryf te implimenteer nie a.g.v. die verskille tussen vervaardiging en mynbou. Die oplossing is om ‘n bedryfsbestuurmodel wat op hierdie filosofieë geskoei is, aan eerstelyntoesighouers in die steenkoolbedryf te verskaf.

Acker, Joseph J; Johnston, Tania M; Lazarsfeld-Jensen, Ann

2014-01-01

Australian natural resource exploration and production companies are employing paramedics to provide emergency medical response, primary health care, injury prevention, and health promotion services in remote locations nationally and internationally. Although Australian paramedic practice has steadily evolved to include increasingly complex medical interventions in the prehospital setting, paramedics are not yet registered health professionals, and in many states and territories their title is not protected. Similarly, tertiary-level education is becoming the entry to practice standard for traditional ambulance paramedics; however, certificate- and diploma-level paramedic courses remain an acceptable pathway to private and industrial paramedic jobs. To ensure acceptable patient safety standards are maintained and to protect all related stakeholders, the role, skills, training, and professional capacity of industrial paramedics must be defined. The study objective was to explore the published literature for a definition for the discipline of industrial paramedicine. A comprehensive systematic analysis was conducted using the EBSCOhost (health), MEDLINE, SCOPUS, and CINAHL electronic databases. The primary search terms "remote", "offshore", "mining", and "oil" were combined with the secondary search terms "paramedic" and "emergency medical services". An initial search using the combined two-term sets identified 870 citations. After application of the inclusion and exclusion criteria to a title and abstract review, 69 citations met the criteria including those discovered by searching the reference lists. Of these, nine citations were excluded because full-text papers could not be found and eight citations were excluded based on review of the full article. The result was 40 articles that discuss the role of paramedics in the remote or offshore environment (ROP) and 12 articles that discuss the provision of emergency medical services in the mining or oil and gas sectors

Occupational health and safety considerations for women employed in core mining positions

2015-06-01

Full Text Available Orientation: Despite various liberalisation and feminisation processes with regard to gender and sex roles, traditionalistic typologies, especially in terms of occupational roles, are seemingly very reluctant to disappear from relevant theoretical discourses, as well as in practice. One of the main issues remains the terrain of physical work. Although women all over the world have been involved in mining activities for centuries, the mining industry has not been an obvious career choice for women. In South Africa, new mining legislation aims to rectify previous inequalities and disadvantages in the mining sector and specifically provides for the inclusion of women in core mining activities. Although well intended, women’s involvement in the core business of mining also exposes them to the various hazards related to mine work. Research purpose: This research determined perceptions regarding the health and safety of women working in core mining positions. Motivation for the study: Currently there is a paucity of published data regarding health and safety challenges pertaining to women employed in the core business of mining. Method: Quantitative and qualitative research paradigms were used (mixed method research design. Quantitative data were collected by means of a structured questionnaire. Qualitative data were collected by means of individual interviews and group interviews. Main findings: From the literature review and the empirical findings it is evident that various factors (physical work capacity, anthropometry and body composition, personal protective equipment, treatment during pregnancy and security measures need to be considered to ensure the health and safety of women employed in core mining positions. Practical/managerial implications: It is evident from the research that exceptional attention should be given to the promotion of the health and safety of women working in the core business of mines to sustain their involvement in the

Joint industry planning platforms for coal export supply chains

1998-12-31

Improving the performance and reducing the costs associated with export logistics chain is critical to the competitiveness of export coal mines. The fundamental practices associated with the use of export logistics chains made up of mine, trucking, rail and port operations are being challenged by the advent of third party operators on rail systems and the use of the Internet. Whilst individual mines can improve their processes to drive down their mining costs, they face major challenges in their endeavour to improve the performance of export logistics chains and reduce the significant logistics costs of moving coal from the mine to export ships, via the shared infrastructure of rail systems and ports. There is an increasing realisation that global competition is not only between mines but between coal export regions that are defined by their rail system and ports infrastructure. The development and use of a joint industry planning platform for the export logistics chains of the Western Australian Grain Industry has demonstrated that an industry facing significant restructuring and increased competitiveness can achieve major throughput and cost reduction gains when stakeholders in export logistics chains share key planning information using the Internet and state of the art planning tools. Joint industry planning platforms for export logistics chains are being considered or are at initial stages of development for a number of Australasian coal export logistics chains. This paper addresses the key components of joint industry planning platforms, the key information that should be shared, the use of the internet and information servers, and the contractual structures required to enable stakeholders of an export logistics chain, who are competitors or potential competitors, to work together to improve the competitiveness of a coal export region. 4 refs., 6 figs.

An overview of brown and black coal mining in the Czech Republic is presented, and problems of the extent of coal reserves and of the profitability of deep black coal mining are discussed. Costs of coal mining in foreign countries are given. Coal mining in the Czech Republic can be expected to be loss-making unless coal prices are increased. Since coal resources in the Czech Republic are limited, additional nuclear power plants will have to be constructed or else coal for power generation will have to be imported. The environmental aspects of coal mining and burning are discussed. Medium-term and long-term solutions to reduce the environmental burden include thermal power plant desulfurization, application of the fluidized-bed combustion regime to coals with large ash and/or sulfur contents, and introduction of gas in towns and power plants. In the short run, large-scale consumers in towns and coal basins should be obliged to accumulate reserves of low-sulfur coal for later use. (J.B.). 2 tabs., 3 figs., 8 refs

An underground coal industry funded project was recently completed on underground mine road construction and maintenance. This paper discusses practical approaches to construction and maintenance of underground mine roads using transferable civil technologies and innovative techniques. Mine pavements are generally low-cost (relative to civil roads), constructed to varying standards using locally available materials to best meet the mobility needs of the mine. Performance of pavements is thus largely dependent on the environmental conditions, quality of the available road making materials, maintenance policies and available resources. This paper explains the causes of bad roads in various underground environments. It details available management strategies, construction and water control techniques, road maintenance and vehicle considerations. It concludes that the trend to larger rubber tires mining equipment needs to be matched with construction and maintenance of high quality road surfaces. For large operations, the total cost due to poor roads may equate to in excess of $A1 million per annum. The strategies outlined in this paper provide the basis for construction and maintenance of underground mine roads to help achieve desired production targets. (author). 2 tabs., 4 figs., 7 refs.

This chapter explains the manifold geobiotechnological possibilities to separate industrial valuable metals from various industrial residues and stored waste products of the past. In addition to an overview of the different microbially catalyzed chemical reactions applicable for a separation of metals and details of published studies, results of many individual investigations from various research projects are described. These concern the separation of rare earth elements from phosphorous production slags, the attempts of tin leaching from mining flotation residues, the separation of metals from spent catalysts, or the treatment of ashes as valuable metal-containing material. The residues of environmental technologies are integrated into this overview as well. The description of the different known microbial processes offers starting points for suitable and new technologies. In addition to the application of chemolithoautotrophic microorganisms the use of heterotrophic microorganisms is explained.

Full text: Many mining and industrial processes generate wastewater that contains a variety of contaminants, such as metals and metalloids. These must be removed to ensure the wastewater is suitable for reuse or safe discharge to the environment. However, mining wastewater treatment processes have traditionally been difficult due to the large range of different contaminants present, requiring a number of complex steps. In current processes, the mining industry generally adds lime to the wastewater to purify it. While often effective, the key issue with this method has been the volume of sludge that forms and the subsequent problems with dealing with this sludge - either to extract the contained water, which often requires additional treatment, or to find enough space for long-term disposal. This complex practice could end soon thanks to a new treatment solution that utilises hydrotalcites. Developed by CSIRO, the treatment overcomes the complexities of lime-based methods and offers a simpler and more water smart process. The CSIRO team found that hydrotalcites, which are layered minerals consisting of aluminium- and magnesium- rich layers, can simultaneously remove a variety of contaminants in wastewater in a single step. Scientists noticed that hydrotalcites begin to form when aluminium and magnesium are present at an ideal ratio and under conditions during neutralisation of acidic waters. As hydrotalcites form, the contaminants become trapped and are easily removed from the wastewater as a solid. Mining wastewater often contains substantial magnesium and aluminium concentrations. This means that we can create hydrotalcites utilising common contaminants that are already present in the wastewater, by simply adjusting their concentrations and adding alkaline compounds to rapidly increase pH. Initial applications have focussed on treating wastewater generated from the mining and extraction of uranium. A range of contaminants including uranium, rare earth elements

Development trends in the Lusatian brown coal mining industry

Lusatia has lived on and with brown coal for over 200 years. Brown coal changed what was once a region in which forestry and agriculture predominated into an industrial region. Thanks to its good combustion properties and high energy yield brown coal very soon became known and popular. It was always the driving force for a rapid development which resulted in an economically sound and technically up-to-date industry in Lusatia. This powerful status of brown coal was however soon exploited for aims which were bound to lead to the downfall of two social structures (during the years from 1933 to 1990) by reason of a regime of unconditional autarchy. The economic and technical development thus initiated certainly brought many advantages, but it also had serious diadvantages. Constant increases in production, as a result of which planned rated outputs were intentionally disregarded, were the rule because production targets had to be met or exceeded. Economic inefficiency led to a scarcity of labour and a shortage of finances. Environmental aims had no priority since production was the absolute, primary objective. Consequently, this regime of economic autarchy ended in an one-way street as far as industry was concerned, a situation which was accompanied by an unexampled destruction of the natural basic living conditions and direct, threatening health hazards to man and nature. The year 1990 saw the beginning of the transition from planned controlled economy to free market economy. The reorganization of the former large combines as corporations was not however merely a formal change, but internally also represented a transformation. The brown coal mining industry manifested its new intention and determination to be economically competitive and unsubsidized in future, to operate in such a way as to be compatible with the environment and to exploit reserves carefully, as well as to render its activities socially compatible.

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)

Full Text Available This study aimed to test the construct validity, factorial invariance and reliability of the Survey Work-Home Interaction-NijmeGen (SWING and to explore whether and how the work-home interaction of various socio-demographic groups differ. Random samples (n = 320 were taken of employees in the mining industry. The confirmatory factor analysis results supported the proposed four-factor structure measuring negative/positive work-home interference and negative/positive home-work interference. The multi-group invariance analyses’ results for two language and ethnic groups also supported the factorial invariance of the SWING. All the scales were found to be reliable. Statistically significant differences in work-home interaction were found, based on age, ethnicity, gender, education, marital status, parental status, language, flexibility at work and individuals who had a partner with a paid job.

Sustainable gold mining management waste policy in Romania

Sustainable mining practices and consistent implementation of the mining for the closure planning approach, within an improved legislative framework, create conditions for the development of creative, profitable, environmentally-sound and socially-responsible management and reuse of mine lands. According to the World Commission on Environment and Development definition, sustainable development is the type of development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Romania has the largest gold reserves in Europe (760 million tons of gold-silver ores, of which 40 million tons in 68 gold deposits in the Apuseni Mountains. New mining projects draw particular attention regarding the environmental risks they cause. Rehabilitation is an ongoing consideration throughout the mine's lifecycle, both from a technical and a financial standpoint. The costs of land rehabilitation are classified as the mine's operating costs. According to Directive 2004/35/EC on environmental liability, the prevention and remedying of environmental damage should be implemented by applying the "polluter pays" principle, in line with the principle of sustainable development. Directive on the management of waste from extractive industries and amending Directive obliges operators to provide (and periodically adjust in size) a financial guarantee for waste facility maintenance and post-closure site restoration, including land rehabilitation. According to the Romanian Mining Law, the license holder has the following obligations related to land use and protection: to provide environmental agreements as one of the prerequisites for a building permit; to regularly update the mine closure plan; to set up and maintain the financial guarantee for environmental rehabilitation; and to execute and finalize the environmental rehabilitation of affected land in the mining site, according to the mine closure plan, including the post

The article describes the results of studying the problems of industrial wastewater treatment using higher aquatic vegetation (hydrophytes) in the former mining enterprise of the Far Eastern Federal District (FEFD). They are aimed at reducing the negative environment impact of toxic tin ore wastes. The material of research were drainage, mine and slime waters as well as Lemna minor and Common reed grass (Phragmites communis). In the work conventional modern physico-chemical, chemical, biological and mathematical-statistical methods were used, as well as in the process of research the methods of atomic absorption spectrophotometry for AAS and mass spectrometry with inductively coupled plasma on ISP-MS ELASN DRS II PerkinElmer was applied. The data obtained in the course of the experiment (2015-2016), indicate that a degree of wastewater treatment, using Lemna minor, is high. Virtually, all compounds of toxic chemical elements contained in industrial wastewater (zinc, cobalt, nickel, cadmium, iron, manganese, lead, etc.) were fully absorbed by a hydrophyte. Pollutant extraction was almost 95%. The obtained results of the study in laboratory conditions proved the possibility of effective use of the Lemna minor for the purification of drainage and mine waters. A key contribution of this paper is the relationship between possible toxic metals contained in industrial wastewater and a higher degree of absorption by their higher aquatic vegetation. These hydrophytes absorb these possible toxic metals in an aqueous medium and are contaminated with these heavy metals.

Responsible Mining—The Impact of the Mining Industry in Poland on the Quality of Atmospheric Air

Full Text Available This article addresses issues of air pollutant emissions by Polish mining industry leaders in the light of corporate social responsibility policy: Kombinat Górniczo-Hutniczy Miedzi Polska Miedź S.A. (KGHM, Polska Grupa Energetyczna S.A. (PGE. The Corporate Social Responsibility (CSR initiative regulates business activities at the level of environmental and social responsibility. Given the location of the “emission activities”, the level of pollutants (SOx, NOx, PMx generated by selected entities in the capital group over the years has been analysed. The aim of the article is to disclose relevant data on the emission reduction of entities as an expression of the actions of taking care of the environment and social protection. Evaluation of the extractive industry in the context of only interventions in the environment without emphasizing the economic and social significance is biased. Therefore, the level of emissivity of the whole economy has been verified against the background of the European Union. The article highlights the importance of coal power in two contexts: the production of electricity based on that fuel in controlled industrial installations and the uncontrolled use of coal in the municipal economy as a problem with a greater nuisance and impact on the quality of inhaled air. Analyses have shown that the widely understood mining industry is still a source of pollution, but power plants and processing plants have significantly reduced the volume of emissions over the years.

To assess ambient air quality at the wider area of a mining-industrial facility in Chalkidiki, Greece, the particulate matter with an aerodynamic diameter of 10 μm (PM(10)) and its content in characteristic elements, i.e., As, Cd, Cu, Fe, Mn, Pb, Zn were monitored for a period of three years (2008-2010). Gravimetric air samplers were employed for the particulate matter sampling at three sampling stations located in the immediate vicinity of the industrial facility and at a neighbouring residential site. Monitoring data indicated that the 3-year median PM(10) concentrations were 23.3 μg/m(3) at the residential site close to the facility and 28.7 μg/m(3) at the site within the facility indicating a minimal influence from the industrial activities to the air quality of the neighbouring residential area. Both annual average and median PM(10) concentration levels were below the indicative European standards, whereas similar spatial and temporal variation was observed for the PM(10) constituents. The average Pb concentrations measured for the three sampling sites were 0.2, 0.146 and 0.174 μg/m(3) respectively, well below the indicative limit of 0.5 μg/m(3). The quantitative and qualitative comparison of PM(10) concentrations and its elemental constituent for the three sampling stations did not indicate any direct influence of the mining-industrial activities to the air quality of the Stratoni residential area.

Garnaut, R.

1982-01-01

The 1981 Green Paper on Mining Royalty Policy for the Northern Territory is a significant landmark in the evolution of fiscal policy in relation to mining in Australia. However, as with mining on Aboriginal land, the Green Paper and the new Royalties Bill have not settled fiscal policy in relation to uranium mining. The Commonwealth still, although presumably temporarily, retains the power to set and to collect royalties on uranium mining. The coincidence that places the most valuable known uranium deposits on Aboriginal land further increases uncertainty about fiscal policy

geochemical characteristics of phosphates used in fertilizer industry at Homs were studied. 28 monthly averaged samples from Palmyrides mining areas were mineralogically and chemically analyzed for P 2 O 5 , CaO and U. Specifically, U content was determined by fluorometry, x-ray fluorescence and γ spectrometry. Results show that the phosphates under study are similar to that exploited at Charquieh mines. U shows a positive correlation with P 2 O 5 and not with CaO. Statistical analyses indicate that fluorometry is more accurate than x-ray fluorescence and γ spectrometry.

The mineral production of Austria, in 1992 - as far as under the supervision of the Austrian Mine Inspectorate, run up to about 50 million t of solid minerals, 1.2 million t of oil and 1.4 billion m 3 of natural gas. 88% of the solid minerals comprised industrial minerals, 4% metals, 4% salt and 4% coal. The solid minerals were produced by 352 open pits and 15 underground mines. 3 of the operations worked both on surface and underground and one mine is a well field operation. In total around 8000 people were employed in the field of mining and mineral processing. The minerals produced represent a value of about 15 billion Austrian Schillings (about 1.25 billion US $), the major part being the industrial minerals sector with a share of 7 billion Austrian Schillings and oil and gas with around 4 billion Austrian Schillings. The industrial minerals sector does not play only in Austrian an important role, but contributes also remarkably to the world production. This comprises mainly magnesite, talc, kaolin and graphite where Austria produces more than 1% of the world production. Summarizing, it can be said that the future of the Austrian mining sector is quite prosperous, perhaps better than in some other traditional mining countries in Europe, where the change from the coal and base metals sector towards the industrial sector has not come so far.

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.

The triple epidemic of silicosis, tuberculosis and HIV infection among migrant miners from South Africa and neighbouring countries who have worked in the South African mining industry is currently the target of regional and international control efforts. These initiatives are hampered by a lack of information on this population. This study analysed the major South African mining recruitment database for the period 1973 to 2012 by calendar intervals and demographic and occupational characteristics. Changes in area of recruitment were mapped using a geographic information system. The database contained over 10 million contracts, reducible to 1.64 million individuals. Major trends relevant to health projection were a decline in gold mining employment, the major source of silicosis; increasing recruitment of female miners; and shifts in recruitment from foreign to South African miners, from the Eastern to the Northwestern parts of South Africa, and from company employees to contractors. These changes portend further externalisation of the burden of mining lung disease to home communities, as miners, particularly from the gold sector, leave the industry. The implications for health, surveillance and health services of the growing number of miners hired as contractors need further research, as does the health experience of female miners. Overall, the information in this report can be used for projection of disease burden and direction of compensation, screening and treatment services for the ex-miner population throughout Southern Africa.

This study was undertaken at the request of the Malaysian nuclear regulatory authorities with the following objectives: to examine the individual steps in the mining, beneficiation, by-product treatment and smelting of tin-bearing minerals so as to highlight possible radiation safety effects and radiological environmental impacts; to make preliminary measurements on operations which are representative of the various steps in the processing of these minerals so as to determine the type and extent of future radiological survey programs; to examine the need for specific measurement techniques with a view to determining future training requirements. A representative operation of each of the steps in the tin mining and processing industry was visited, measurements were made and samples were collected to assess both the in-plant safety and offsite environmental effects of the operation. The results of measurements of gamma dose-rates, radon daughters-in-air, thoron daughters-in-air and radioactive respirable dusts are presented.

Technical-economic parameters of the new oil shale mining-chemical complex in Northeast Estonia

Kuzmiv, I.; Fraiman, J.

2006-01-01

The history of oil shale mining in Estonia has reached its century mark. Three oil shale branches have been formed and have been working on the basis of Estonian oil shale deposits: the mining industry (underground and surface extraction), the power industry (heat and electric energy generation), and the chemical industry (gas and synthetic oils). The authors attempted to summarize the experience of the activities of these branches and to make into a whole the results of their research developments in the past years, as well as to form a notion about perspectives of oil shale in Estonia. Variants of the mining-chemical oil shale complex production and trade patterns differed from used ones. Mining methods, thermal processing of oil shale, and solid, liquid, and gas waste recovery have been studied, analyzed, and worked out up to the present. Setting up a flexible trade structure within the framework of that complex is considered the main economic mechanism capable of balancing production costs of such a complex with its earnings, which could respond properly to any, even peak, fluctuations of the market for final products processed from oil shale. Data of the working 'Estonia' oil shale mine were used as the basis of the analysis and practical conclusions. Information on the mine being projected in the region of Ojamaa in the northeast of Estonia was taken as the data of the worthwhile supplier. Oil shale processing chemical complex is considered in two structural alternatives: in technological chain with the 'Estonia' mine (the first variant), and the projected mine of a new technical level (the second variant).

The greatest volume of useful carbon-energetical and carbon-technological resources in the countries of the world consists of coal. Most likely, problems of the development of coal wining technology and coal consumption will interest scientists and mining engineers for a long time. Moreover, competing with the petroleum and gas industries becomes increasingly difficult. Considerable increases in coal production in countries with warm climates, and favourable mining and geological conditions also damages the international market for the coal industries of Russia (and Australia, India, and Vietnam). In a situation of critical deficits in both financial and material means in Russia, it is necessary to change the structure of the means of production and investment policies for the development of coal mining at every individual mine. 1 fig

A European Competence Framework for Industrial Pharmacy Practice in Biotechnology

Jeffrey Atkinson

2015-07-01

Full Text Available The PHAR-IN (“Competences for industrial pharmacy practice in biotechnology” looked at whether there is a difference in how industrial employees and academics rank competences for practice in the biotechnological industry. A small expert panel consisting of the authors of this paper produced a biotechnology competence framework by drawing up an initial list of competences then ranking them in importance using a three-stage Delphi process. The framework was next evaluated and validated by a large expert panel of academics (n = 37 and industrial employees (n = 154. Results show that priorities for industrial employees and academics were similar. The competences for biotechnology practice that received the highest scores were mainly in: “Research and Development”, ‘“Upstream” and “Downstream” Processing’, “Product development and formulation”, “Aseptic processing”, “Analytical methodology”, “Product stability”, and “Regulation”. The main area of disagreement was in the category “Ethics and drug safety” where academics ranked competences higher than did industrial employees.

Integrating Industrial Ecology Thinking into the Management of Mining Waste

Directory of Open Access Journals (Sweden)

Éléonore Lèbre

2015-10-01

Full Text Available Mining legacies are often dominated by large waste facilities and their associated environmental impacts. The most serious environmental problem associated with mine waste is heavy metals and acid leakage through a phenomenon called acid mine drainage (AMD. Interestingly, the toxicity of this leakage is partly due to the presence of valuable metals in the waste stream as a result of a diversity of factors influencing mining operations. A more preventive and recovery-oriented approach to waste management, integrated into mine planning and operations, could be both economically attractive and environmentally beneficial since it would: mitigate environmental impacts related to mine waste disposal (and consequently reduce the remediation costs; and increase the resource recovery at the mine site level. The authors argue that eco-efficiency and resilience (and the resulting increase in a mine’s lifetime are both critical—yet overlooked—characteristics of sustainable mining operations. Based on these arguments, this paper proposes a framework to assist with identification of opportunities for improvement and to measure this improvement in terms of its contribution to a mine’s sustainability performance.

2017-01-01

This paper presents a study of the “Rosa Porriño” granite, which is known worldwide and has been marketed for more than 50 years, through the application of geologic-mining techniques. These techniques are widely used for analysing rock masses with the aim of commercially exploiting them. The basis is the general criteria for the characterization of geological and mining parameters: the lithologies present and their distribution, types and location of fractures, the industrial quality of the rock and the location of the exploitable rock volumes, previous activity, planning possibilities and rationalization of the exploitation, to name a few. This geological and mining information was used to make a map of the industrial qualities, forming the basis for the estimation of reserves and their distribution within the deposit. The application of geostatistical techniques allowed the definition of the three dimensions and thus the existing volumes corresponding to each industrial quality (defined in the geological-mining cartography). Four different qualities were defined and their volumes estimated, namely first and second qualities for granite suitable for its use as ornamental stone or other applications of high added value; third quality for the granite suitable for its use as a construction material (generally of smaller volume than the previous qualities) and the fourth quality for the granite for aggregates. The overburden zones were determined as well. Once the reserves of the qualities and their spatial distribution within the deposit are known, different alternatives for a rational exploitation can be considered for the existing operating units. This modelling enables a more effective and efficient mining operation, with controlled, lower environmental impact and thus with a more sustainable exploitation of the mining resources. [es

2014-01-01

Implementation of clean mining technology at coal mines is crucial to protect the environment and maintain balance among energy resources, consumption, and ecology. After reviewing present coal clean mining technology, we introduce the technology principles and technological process of paste backfill mining in coal mines and discuss the components and features of backfill materials, the constitution of the backfill system, and the backfill process. Specific implementation of this technology and its application are analyzed for paste backfill mining in Daizhuang Coal Mine; a practical implementation shows that paste backfill mining can improve the safety and excavation rate of coal mining, which can effectively resolve surface subsidence problems caused by underground mining activities, by utilizing solid waste such as coal gangues as a resource. Therefore, paste backfill mining is an effective clean coal mining technology, which has widespread application. PMID:25258737

Abandoned mines, mountain sports, and climate variability: Implications for the Colorado tourism economy

Science.gov (United States)

Todd, Andrew; McKnight, Diane; Wyatt, Lane

Until recently, the allure of the mountains in the American West was primarily extractive, for commodities like timber, water, and precious metals [Baron et. al., 2000]. Now, the effective marketing and management of the regions “white gold” by the ski industry has stimulated significant recreation-related growth and development in the last several decades. Under an uncertain climatic future, however, these burgeoning industries, and the communities that have grown up in relation to them, are facing water quality constraints inherited from historical mining practices, causing mountain water to become a limited resource more valuable than the precious metals of the past. Further, the current lack of proven, in-situ approaches for addressing distributed, mining waste pollution of fresh water complicates potential remediation efforts.

James L Dippo; Tim Erikson; Kris Hess

2009-07-10

The fuel cell hybrid mine loader project, sponsored by a government-industry consortium, was implemented to determine the viability of proton exchange membrane (PEM) fuel cells in underground mining applications. The Department of Energy (DOE) sponsored this project with cost-share support from industry. The project had three main goals: (1) to develop a mine loader powered by a fuel cell, (2) to develop associated metal-hydride storage and refueling systems, and (3) to demonstrate the fuel cell hybrid loader in an underground mine in Nevada. The investigation of a zero-emissions fuel cell power plant, the safe storage of hydrogen, worker health advantages (over the negative health effects associated with exposure to diesel emissions), and lower operating costs are all key objectives for this project.

Philips Kembaren

2014-09-01

Full Text Available Design driven innovation has emerged to be an alternative way to generate sustainable competitive products or services. Previous research has recently revealed succesful practices of design driven innovation in various industries. However, little has been known about the creative companies that practice design driven innovation, especially in developing countries. This research investigates the existence and practices of design-driven innovation in the Indonesian creative industry. Based on interviews with the design-preneurs of the creative industry, one of the results of this study reveals how the Indonesian creative industry creates new meanings that are embedded into new products. Based on the identification, a framework to create new meaningsis resulted which consists of a set of key processes, such as sensing, sensemaking, specifying, setting up and storytelling. The practical contribution of this research is that this identified framework can be adopted by any creative companies interested in improving their innovation capability.

Quantification practices in the nuclear industry

An analysis of workers' morale in the coal mining industry using principal component analysis

Energy Technology Data Exchange (ETDEWEB)

Armstrong, J; La Court, C; Pearson, J M

1987-03-01

This paper looks at labour morale in the coal mining industry from 1967 to 1984. In particular it examines absenteeism, turnover and accidents over that period, as well as constructing an index of morale based on these variables. The data are taken from the North Nottinghamshire and South Yorkshire coal areas, and a comparison is made between these areas in the period leading up to the industrial action in 1984/85. The indices constructed indicate that morale, as measured by the first principal component, increased considerably during the years before the 1984 industrial dispute and that low morale was an unlikely reason for the dispute, although morale in South Yorkshire, a strike area, was lower than in North Nottinghamshire, largely a non-strike area. The steep rise in morale in both North Nottinghamshire and South Yorkshire follows closely the rise in unemployment nationally and may simply be an indication of conventional industrial relations assumptions that manifestations of negative worker attitudes are greatest when jobs are relatively plentiful, and considerably less so when jobs are scarce.

Siemens' innovative role in mining technology

Energy Technology Data Exchange (ETDEWEB)

1990-07-01

The growth of the mining industry in South Africa has played a decisive role in the industrial development of the country. As mining activities expanded, the need for energy production increased and as of late mining is becoming more mechanised and the need for more energy as well as automation is growing. The origins of Siemens operations in South Africa date back to the humble beginnings of the mining era, when the company provided the first generator and floodlights to illuminate the famous 'Big Hole' of the diamond mine at Kimberley as well as hydro-electric plants in 1895 on the Crocodile River and Blyde River respectively to supply the newly established mines in the Lydenburg district with electric power. 7 figs.

Uranium mining in the Canadian social environment of the eighties

International Nuclear Information System (INIS)

Dory, A.B.

1981-11-01

The attitude of the Canadian public to the mining industry as a whole has changed in recent years to one of mistrust because of the public perception of mining as environmentally harmful and humanly degrading. In addition, uranium mining has had to cope with the public fear of radiation. The uranium mining industry is closely regulated by the Atomic Energy Control Board, not only in the area of radiation protection but also in other fields affecting worker health and safety. Uranium mining has been the subject of many hearings in Canada, and all but one have concluded that it is environmentally and socially acceptable. It is up to the mining industry to convey this message to the public

Influence of Government economic policies on mining legislation

Energy Technology Data Exchange (ETDEWEB)

Jakob, K F

1980-01-01

As we know from experience, the relation between state and economy is characterized by more or less strong tensions. The following three groups have always claimed the right to dispose of mineral resources: the state - in former times the sovereign -, the landowners, and the mining industry. The first one has based his claim on his official power and has taken the view that he alone could protect the interests of the general public in winning mineral resources. The second ones have relied on their titles to real estates which basically cover unlimited depth. With the intent to work the mines, the mining industry refers to its know-how, performance and readiness, thus alleging that they would serve the national economy best. The historical development of mining laws has finally been characterized by a shift in priorities within these naturally strained relations which exist between state, landowners, and mining industry. It is examined how the emphasis has been shifted in this relationship in the course of time, with special consideration of the relationship between state and mining industry. Which rules of law the legislator intends to make with regard to mining laws will always depend on the question as to which economic policy the state intends to pursue.

Giving back the land - a look at open-cast mining. [South Africa

Energy Technology Data Exchange (ETDEWEB)

Thompson, G.C.

1983-01-01

The mining industry, particularly the gold mining industry, has, since 1886, dominated the economic life of South Africa. Revenues from mining have provided the impetus which led to the development of this country from subsistence agriculture to one of industrial power. Coal is South Africa's second largest foreign exchange earner after gold, but opencast mining necessitates the alienation of agricultural land, albeit temporarily. The coal industry is improving the speed, and standards, of land reclamation.

Methane in German hard coal mining

International Nuclear Information System (INIS)

Martens, P.N.; Den Drijver, J.

1995-01-01

Worldwide, hard coal mining is being carried out at ever increasing depth, and has, therefore, to cope with correspondingly increasing methane emissions are caused by coal mining. Beside carbon dioxide, chloro-fluoro-carbons (CFCs) and nitrogen oxides, methane is one of the most significant 'greenhouse' gases. It is mainly through the release of such trace gases that the greenhouse effect is brought about. Reducing methane emissions is therefore an important problem to be solved by the coal mining industry. This paper begins by highlighting some of the fundamental principles of methane in hard coal mining. The methane problem in German hard coal mining and the industry's efforts to reduce methane emissions are presented. The future development in German hard coal mining is illustrated by an example which shows how large methane volumes can be managed, while still maintaining high outputs at increasing depth.

Luthra, S.; Garg, D.; Haleem, A.

2014-04-01

Environmental sustainability and green environmental issues have an increasing popularity among researchers and supply chain practitioners. An attempt has been made to identify and empirically analyze green supply chain management (GSCM) practices in Indian automobile industry. Six main GSCM practices (having 37 sub practices) and four expected performance outcomes (having 16 performances) have been identified by implementing GSCM practices from literature review. Questionnaire based survey has been made to validate these practices and performance outcomes. 123 complete questionnaires were collected from Indian automobile organizations and used for empirical analysis of GSCM practices in Indian automobile industry. Descriptive statistics have been used to know current implementation status of GSCM practices in Indian automobile industry and multiple regression analysis has been carried out to know the impact on expected organizational performance outcomes by current GSCM practices adopted by Indian automobile industry. The results of study suggested that environmental, economic, social and operational performances improve with the implementation of GSCM practices. This paper may play an important role to understand various GSCM implementation issues and help practicing managers to improve their performances in the supply chain.

Energy Technology Data Exchange (ETDEWEB)

Wilson, Emma; Schwarte, Christoph; Cotula, Lorenzo; Garside, Ben; Siegele, Linda

2009-01-15

The oil, gas and mining industries look set to remain major players in global development, despite urgent efforts to end the world's fossil fuel dependency and diversify energy sources. The activities of the extractive industries often impinge directly, and sometimes harshly, on communities and the environment. But local people are rising to the challenge. From Azerbaijan to Nigeria, Kazakhstan, Mali and Mongolia, citizens are working to promote transparency, accountability and responsible practice in these industries. A lack of skills and resources can impede crucial progress – so knowing the tools that work to make industry accountable is key.
