  3. 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)

    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.

    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.

  13. African mining '91

    International Nuclear Information System (INIS)

    1991-01-01

    The second 'African Mining' conference was held in June 1991, and followed the first event held in May 1987. That full four-year period was characterized by substantial changes in the political and economic climate of many countries in both hemispheres. The results of many of these changing facets of our industry are described in the papers in African Mining'91. Many of the papers deal with advances in technology, which is the main reason for the meeting. There are 37 papers under the headings general, mining, metallurgy and geology and exploration. Most papers are concerned with gold, copper and mineral mining. One paper concerning uranium mining operations in Namibia is indexed separately. (author)

  14. The role of waste sorting in the South African gold-mining industry

    International Nuclear Information System (INIS)

    Freer, J.S.; Boehme, R.C.

    1985-01-01

    The absolute potential for sorting waste from run-of-mine Witwatersrand gold ores normally lies between 60 and 90 per cent by mass. At present, the practical potential lies between 40 and 50 per cent. Yet few mines achieve a waste rejection of even 30 per cent. The average waste rejection for industry, including underground sorting, fell from 19,6 per cent in 1959 to 10,1 per cent in 1983, as industry moved from labour-intensive, multistage comminution, incorporating washing, screening, and sorting, to single-stage run-of-mine milling. Most of the sorting is still being done by hand; yet photometric and radiometric sorting machines of high capacity are available. More recently, a sorter based on neutron activation and the subsequent isomeric radioactive decay of gold itself was designed. This paper examines the case for an increased role for sorting in the South African gold-mining industry brought about by the increasing cost of power for milling and the possibility of extracting gold from low-grade reject fractions by heap leaching

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

    Butchart, A

    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.

  16. The South African coal mining industry: A need for a more efficient and collaborative supply chain

    Directory of Open Access Journals (Sweden)

    2011-11-01

    Full Text Available It is estimated that about two-thirds of global coal is used for power generation and that, in the next 20 years, over 70% of the demand for coal will come from China and India. 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.

    Full Text Available Abstract Background 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. Methods 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. Results 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. Conclusions 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.

  2. 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.

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

    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

    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.

    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

    The French atomic energy commission (CEA) is involved in the mining industry in several ways: - in the front-end of the nuclear industry through its daughter companies and participations in the exploration and exploitation of uranium ores, but also of gold and alloy metals with a 26% participation in Eramet company, the world leader of manganese and nickel. This activity is the main occupation of Cogema daughter company, via the Areva holding; - in the back-end of the nuclear fuel cycle with the delicate problem of the management of radioactive wastes; - in parallel with the nuclear industry through an important activity in semiconductor materials (FCI and SMTElectronics); - and finally through various research works on several mineral compounds. This article focusses on the fuel cycle aspects of the CEA activities and concludes with the research works carried out today on thermonuclear fusion. (J.S.)

    1997-01-01

    The risks from mining and processing of ores is reviewed on a generic basis with particular reference to some of the confusions which can arise due to lack of consistency or common logic in the use of exclusion, exemption and clearance. The difference in exclusion and exemption are challenged by comparing doses received in high background radiation areas and the doses received from a mining practice. The common principle of risk to the human species is not applied consistently. The differences between IAEA recommendations and local regulatory conditions are compared, and the use of exemption levels as clearance levels is considered. A case study on management of mine tailings is presented with special focus on the use of clearance levels. In all areas of review the interpretation of regulation is subject to confusion resulting from inconsistencies which can distort free market economics. (author)

    Energy Technology Data Exchange (ETDEWEB)

    Krzykawski, Michal [FAMUR Group, Katowice (Poland)

    2009-08-27

    Global suppliers of longwall systems focus mainly on maximising the efficiency of the equipment they manufacture. Given the fact that, since 2004, coal demand on world markets has been constantly on the increase, even during an economic downturn, this endeavour seems fully justified. However, it should be remembered that maximum efficiency must be accompanied by maximum safety of all underground operations. This statement is based on the belief that the mining industry, which exploits increasingly deep and dangerous coal beds, faces the necessity to implement comprehensive IT systems for managing all mining processes and, in the near future, to use unmanned mining systems, fully controllable from the mine surface. The computerisation of mines is an indispensable element of the development of the world mining industry, a belief which has been put into practice with e-mine, developed by the FAMUR Group. (orig.)

  5. South African gold and uranium ore mining in 1976

    International Nuclear Information System (INIS)

    Hentrich, W.

    1977-01-01

    1976 was a difficult year for the South African gold and uranium ore mining industry, the region of Witwatersrand (Transvaal province) producing some 75% of all the gold mined in the western world besides being an important producer of uranium oxide. Despite the gold production, declining since 1971, not showing a downward tendency anymore as far as the quantity was concerned, the economic result, however, deteriorated as a consequence of continuously falling gold prices, but also on account of the inflationary rise in wages and the prices for energy and materials. Much higher prices for uranium oxide, which some mines produce as interim products from the 'degolded' slurries of their gold ore leaching plants, improved the economic overall result only to a small degree.

    Hinrichsen, P.J.

    2004-01-01

    South Africa has an extensive mining industry, with total mineral sales in 2002 being R140 billion and total mineral exports being R110 billion. In this same year, the industry employed over 400 000 workers. When the International Atomic Energy Agency Regulations for the Safe Transport of Radioactive Material (TS-R-1 [ST-1 Revised]) (the Regulations), was adopted by the regulatory body, the National Nuclear Regulator (NNR), in June 2001, the Industry requested the drafting of a guide on the interpretation of these regulations for NORM. This paper has arisen from the drafting of such a guide, drafted with the end-user in mind, giving an interpretation of the application of the Regulations to NORM. The paper is more ''Qualitative'' than ''Quantitative'' and raises a number of ''peculiar'' aspects of the application of the Regulations to NORM

  13. Impacts of Canada's uranium mining industry

    International Nuclear Information System (INIS)

    Holman, G.J.

    1982-05-01

    This study examines economic and environmental impacts of uranium mining in Canada and compares these impacts with those of other extractive and energy industries. The uranium industry generates taxes and royalties, income, employment, foreign exchange earnings, security of energy supply, and technological spinoffs. The indirect impacts of the industry as measured by employment and income multipliers are lower than those for other types of mining and comparable to oil and gas because of the high proportion of costs withdrawn from the economy in the form of taxes and operator margin. Social costs are primarily occupational hazards. Uranium mining probably has a lower non-health environmental impact than other mining industries due to much smaller throughputs and transportation requirements. Residents of the area surrounding the mine bear a disproportionate share of the social costs, while non-residents receive most of the benefits

  14. African Mining, Gender and Local Employment

    Science.gov (United States)

    Tolonen, A.; Kotsadam, A.

    2014-12-01

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

    Although reductions in the tax of injuries and accidents have been observed in recent years, Mining is still one of the highest risks industries. The basic causes for occurrence of fatalities can be attributed to unsafe conditions and unsafe acts. In this scene is necessary to identify safety problems and to aim the effective solutions. On the other hand, the developing countries dependence on primary industries as mining is evident. In the Peruvian economy, approximately 16% of the GNP and more than 50% of the exportations are due to the mining sector, detaching its competitive position in the worldwide mining. This paper presents fatal accidents analysis in the Peruvian mining industry, having as basis the register of occurred fatal accidents since year 2000 until 2007, identifying the main types of accidents occurred. The source of primary information is the General Mining Direction (DGM) of the Peruvian Mining and Energy Ministry (MEM). The majority of victims belongs to tertiary contractor companies that render services for mine companies. The results of the analysis show also that the majority of accidents happened in the underground mines, and that it is necessary to propose effective solutions to manage risks, aiming at reducing the fatal accidents taxes.

    Presents an interview in question and answer format with the deputy chairman of Gosgortekhnadzor (Committee for Supervision of Industrial Work Safety and Mining Supervision) in which he discusses two recent fatal accidents in the Yasinovskaya-Glubokaya and Chaikino coal mines and identifies areas where safety needs to be improved (more automation, protective devices, ventilation etc.). Discusses the particular problems involved with deep mining (20% of mines are now deeper than 700 m and 27 mines are deeper than 1000 m), such as fires, dust, methane, rock falls, insufficient maintenance and strata control and poor ventilation. Confirms that a large number of accidents is due to poor organization and stresses the fact the coal industry must be subjected to perestroika (restructuring) as much as other areas of society.

  17. Self-regulation in the mining industry

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

    Vrentsovski, Angele

    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

    1989-01-01

    This publication reports on a visit by four British MPs to the South African Coal Industry (SACI), made under the auspices of the SACI Committee which represents all the major coal exporting companies of South Africa. It is a private industry which operates independently of both the Government and the Chamber of Mines and does not benefit from any Government Subsidies. The aim of the visit was to investigate the SACI against a background of international pressure against an industry which appears to be a major example of change in South Africa. The visit programme included presentations on the South African coal industry in general, industrial relations and safety and research in the mining industry. Visits were made to both an underground mine and an opencast mine, a collieries training college, hospital, school, mine village and a coal terminal. At the end of the visit the delegation drew the conclusions that the South African coal industry is now organised on a totally non-discriminatory basis, offering employment and promotion opportunities to all workers regardless of their race and that there is therefore no justification for singling out this industry as a victim of sanctions policy.

  5. Public consent for mining: An industry viewpoint

    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

    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

  8. 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

    2002-01-01

    South Africa has a very large mining and minerals processing industry exploiting a variety of ores and minerals containing elevated levels of NORM. The industry employs more than 300,000 persons. Doses have been assessed to workers in the mining industry in South Africa. In the gold mining industry radon measurements have been performed since the early 1970s. Regulations have been in force since 1990. The mean annual dose to underground gold mine workers, mostly from radon progeny, is about 5 mSv with maximum doses exceeding 20 mSv. The maximum annual dose to surface workers in gold mines is 5 mSv. In South African coal mines the mean annual dose from inhalation of radon decay products has been estimated from limited radon concentration measurements to be about 0.6 mSv. In the phosphoric acid and fertilizer production industry the doses to the workers do not exceed 6 mSv/y. There are 3 mineral sands operations in South Africa, for which the maximum annual dose to workers is 3 mSv. One open pit copper mine contains elevated levels of U, which is extracted as a by-product. The maximum annual doses to workers are 5 mSv for workers in the mine and 20 mSv for workers in the metallurgical plant. Worker doses in the metallurgical plant have since been reduced with the introduction of radiation protection measures

    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)

South Africa extracts minerals with naturally occurring radionuclides, amongst which uranium, monazite and zircon. Two case studies involving environmental restoration activities that are typically associated with mining and minerals processing are discussed. The first case study, Katdoringbos, describes the restoration of a contaminated site where scrap material originating from the mining and minerals processing facilities had been recycled. The other case study, Crown 4, deals with the restoration of a contaminated site where a mine tailings dam had been removed and the owner of the land wished to develop it for commercial exploitation.

    Water and soil natural radioactivity is a well known phenomenon which can produced by variable concentrations of uranium and thorium series radionuclides. Generally, the relevant radiological hazard is not important; however, some radiation protection problems can occur in particular industrial processes involving the treatment of large quantities of materials. In this case a high concentration of radioactive substance (NORM: nationally occurring radioactive materials) can be found at special points of the plant, in the manufacture by-products and in the waters. Sometimes the national radioactivity concentration can be so high to raise radiation protection problems which can be assimilated in a sense to the ones faced in the presence, handling, and disposal of non-sealed radioactive sources. In this paper the following mining and hydrocarbon extraction plants were particularly taken into account: (a) industries using zircon sands to produce refractory and ceramic materials; (b) phosphorites manufacture to prepare phosphoric acids, plasters and fertilizers (c) hydrocarbon extraction and treatment processes where formations of low specific activity (L.S.A.) scales and sludges are produced. The relevant results and the possible radiation protection risks for the professional exposed staff will be reported. A special emphasis will be given to some african phosphorites (boucraa, togo, morocco), and L.S.A. scales (tunisia, congo, Egypt). 4 figs., 5 tabs.

    The US mining industry has taken its licks over the years but remains economically viable and able to meet global demands, says R.R. Beebe, a retired executive with Homestake Mining Company in San Francisco. Despite a new-found environmental sensitivity, one of the industry's major problems is its negative public image, Beebe admits. open-quotes Mining's record of environmental insensitivity and demands for low-cost access to public lands has burdened an industry now largely committed to doing business fairly, responsibly, and with minimum environmental disturbance,close quotes he asserts. Another part of its image problem deals with the place of mining in the economic scheme of things. Too many people view mining as a open-quotes sunset industry,close quotes he says, making it difficult for the industry to get a fair hearing on the public stage. open-quotes Even the industry's top executives seem to prefer a low profile, rarely serving in government posts...and almost never seeking public platforms from which to expound their views,close quotes Beebe complains. The size of the US mining industry and the importance of the minerals it supplies to domestic industry make it a significant contributor to the nation's standard of living, Beebe emphasizes. This makes it an industry worth saving

    Queensland's multi-billion dollar mining industry, and the industries it supports, continues to play a vital role in the economy of the State and the nation. According to Australian Bureau of Statistics figures, Queenland produces nearly half of the black coal mined in Australia, 70% of the copper, 54% of the silver, 42% of the lead, 31% of the zinc, 40% of the tungsten, 25% of the bauxite and tin, 46% of the rutile, and 9% of the gold.

  9. Radon and radon daughters in South African underground mines

    International Nuclear Information System (INIS)

    Rolle, R.

    1980-01-01

    Radon and the radon daughters are the radionuclides which primarily determine the level of the radiation hazard in underground uranium mines and to a smaller extent in non-uranium mines. Radon is a gas, and its daughters adsorb on aerosol particles which are of respirable size. The hazard thus arises from the alpha decay of radon and its daughters in contact with lung tissue. Radon is itself part of the uranium decay chain. The major radionuclide, 238 U, decays successively through thirteen shorter-lived radionuclides to 206 Pb. Radon is the only gaseous decay product at room temperature; the other twelve are solids. The main hazard presented by the uranium decay chain is normally determined by the radon concentration because gaseous transport can bring alpha emitters close to sensitive tissue. There is no such transport route for the other alpha emitters, and the level of beta and gamma radiation caused by the uranium decay chain generally presents a far lower external radiation hazard. Radon itself is the heaviest of the noble gases, which are He, Ne, Ar, Kr, Xe and Rn. Its chemical reactions are of no concern in regard to its potential hazard in mines as it may be considered inert. It does, however, have a solubility ten times higher than oxygen in water, and this can play a significant part in assisting the movement of the gas from the rock into airways. Radon continuously emanates into mine workings from uranium ores and from the uranium present at low concentrations in practically any rock. It has been found that the control of the exposure level is most effectively achieved by sound ventilation practices. In South African mines the standard of ventilation is generally high and exposure to radon and radon daughters is at acceptably low levels

    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

  13. Economical Recovery of By-products in the Mining Industry

    2001-12-05

    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

    Australia's economic, demonstrated resources of uranium (U) at the end of 1996 amounted to 622,000 tonnes U, the largest of any country. Uranium is currently produced at two mining/milling operations in Australia - Ranger in the Alligator Rivers Region of the Northern Territory, and Olympic Dam in South Australia. Improved market conditions and recent changes to Government policies have encouraged Australian companies to commit to the expansion of existing operations and the development of new uranium mines. Australia's annual production is likely to increase from its present level of 6000 tonncs (t) U 3 O 8 to approximately 12 000 t U 3 O 8 by the year 2000. (author)

    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.)

    1994-01-01

    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.

  19. How the environmental community views the mining industry

    International Nuclear Information System (INIS)

    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

  1. Environmental and community issues and the mining industry

    International Nuclear Information System (INIS)

    Crowson, P.

    1998-01-01

    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)

  2. 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.

    1984-03-01

    A review of the US uranium mining industry has revealed a generally depressed industry situation. The 1982 U 3 O 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 3 O 8 production for the years 1983 and 1990. Reactor fuel demand is estimated to increase from 15,900 tons to 21,300 tons U 3 O 8 respectively. U 3 O 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 222 Rn emission levels for a group of 27 uranium mines. It is shown that 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 222 Rn emissions is predicted due to 17 of the mines being shutdown and sealed. The estimated total 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

    2008-01-01

    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)

    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

    In the previous paper (Hussain and Karmakar in Inst Eng India Ser, 2014. doi: 10.1007/s40033-014-0058-0), the concepts of input-output transaction matrix and multiplier were explained in detail. Input-output multipliers are indicators used for predicting the total impact on an economy due to changes in its industrial demand and output which is calculated using transaction matrix. The aim of this paper is to present an application of the concepts with respect to the mining industry, showing progress in different sectors of mining with time and explaining different outcomes from the results obtained. The analysis shows that a few mineral industries saw a significant growth in their multiplier values over the years.

  16. Public Consultation Processes in Greenland Regarding the Mining Industry

    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.

    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.

    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.

    Worldwide efforts are ongoing in optimizing medical treatment by searching for the right medicine at the right dose for the individual. Metabolism is regulated by polymorphisms, which may be tested by relatively simple SNP analysis, however requiring DNA from the test individuals. Target genes for the efficiency of a given medicine or predisposition of a given disease are also subject to population studies, e.g., in Iceland, Estonia, Sweden, etc. For hypothesis testing and generation, several bio-banks with samples from patients and healthy persons within the pharmaceutical industry have been established during the past 10 years. Thus, more than 100,000 samples are stored in the freezers of either the pharmaceutical companies or their contractual partners at universities and test institutions. Ethical issues related to data protection of the individuals providing samples to bio-banks are several: nature and extent of information prior to consent, coverage of the consent given by the study person, labeling and storage of the sample and data (coded or anonymized). In general, genetic test data, once obtained, are permanent and cannot be changed. The test data may imply information that is not beneficial to the patient and his/her family (e.g., employment opportunities, insurance, etc.). Furthermore, there may be a long latency between the analysis of the genetic test and the clinical expression of the disease and wide differences in the disease patterns. Consequently, information about some genetic test data may stigmatize patients leading to poor quality of life. This has raised the issue of 'genetic exceptionalism' justifying specific regulation of use of genetic information. Discussions on how to handle sampling and data are ongoing within the industry and the regulatory sphere, the European Agency for the Evaluation of Medicinal Products (EMEA) having issued a position paper, the Council for International Organizations of Medical Sciences (CIOMS) having a working

    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.

    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.

    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

    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.

  18. Corporate social responsibility in the mining industry: Criteria and indicators

    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.

  6. Applying a small NPP in the Argentine mining industry

    International Nuclear Information System (INIS)

    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)

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

    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.

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.

    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.

  19. African women, industrialization and another development. A global perspective.

    1982-01-01

    Historically, the women of Africa have been differentially integrated into the world economic system, serving primarily as a labor reserve and a mainstay for the subsistence and reproductive sectors. If and when necessary, female proletarianization can come into effect. African women, by virtue of their strategic role in traditional food systems, have acquired certain skills compatible with labor intensive food processing industries. Consequently, in some countries they have been involved in the handling, processing, and packing of food. In many 3rd world nations regulations protecting minimum wage levels do not exist and collective bargaining activities are not strongly in force. Economic hardship and the desperate need to survive can lead some groups to accept even lower wages. Consequently, although the employment of women at lower wages violates the principle of equal pay for equal work, agroindustries with monopolies can deliberately and with impunity hire women at lower wages than men. In general, when women are hired in industries the nature of their employment is precarious, frequently being of a casual and seasonal nature and in greatest demand during peak periods. In an effort to understand the implications of industrialization for African women a global perspective is necessary, for at present the incorporation of the African women in direct industrialization is minimal. Racism has played an important role in the exploitation of the African continent, and no serious study of class and gender inequality in Africa can overlook that important fact. Numerous studies have shown how industry perpetuates the sexual division of labor. Even in the industrialized nations, women often have held the least paid and most precarious jobs in industry. Women's vulnerability is further worsened by several factors, the most obvious being their reproductive capabilities. In addition to being more vulnerable to industrial hazards, their employment can be truncated by

  1. Applications of radio frequency identification systems in the mining industry

    Energy Technology Data Exchange (ETDEWEB)

    Hind, D J [Davis Derby Ltd., Derby (United Kingdom)

    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.

    Guidelines for implementing the World Health Organization's Framework Convention on Tobacco Control (FCTC) recommend prohibiting tobacco industry corporate social responsibility (CSR) initiatives, but few African countries have done so. We examined African media coverage of tobacco industry CSR initiatives to understand whether and how such initiatives were presented to the public and policymakers. We searched two online media databases (Lexis Nexis and Access World News) for all news items published from 1998 to 2013, coding retrieved items through a collaborative, iterative process. We analysed the volume, type, provenance, slant and content of coverage, including the presence of tobacco control or tobacco interest themes. We found 288 news items; most were news stories published in print newspapers. The majority of news stories relied solely on tobacco industry representatives as news sources, and portrayed tobacco industry CSR positively. When public health voices and tobacco control themes were included, news items were less likely to have a positive slant. This suggests that there is a foundation on which to build media advocacy efforts. Drawing links between implementing the FCTC and prohibiting or curtailing tobacco industry CSR programmes may result in more public dialogue in the media about the negative impacts of tobacco company CSR initiatives.

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.

    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

    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.

    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.

    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.

    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. The 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. The problems involved in designing and certifying a system for use in hazardous areas are described, with particular reference to the problems of inadvertent detonator ignition by radio systems. Applications of RFID systems in the mining industry are described, covering applications both on the surface and underground. 1 ref., 10 figs.

  1. The Atomic Energy Control Board and the uranium mining industry

    International Nuclear Information System (INIS)

    Duncan, R.M.

    The Atomic Energy Control Board controls prescribed substances and nuclear facilities through a licensing system. It is only recently that this system has been applied to the uranium industry. There are four stages in the licensing procedure before a Mine-Mill Facility Operating Licence is issued: exploration requires an underground exploration permit; site approval is needed before the start of the development stage; development approval is required before the construction of the mill and waste management facilities and depends on the information in a preliminary safety report; the granting of a final operating licence occurs after the Board is satisfied with the final safety report, operating policies and principles, tailings management, and decommissioning plans. The Board has resource management policies designed to ensure that uranium reserves are available to meet Canada's needs. The administration of safeguards is also the Board's responsibility. (LL)

  6. Development trends in the Lusatian brown coal mining industry

    International Nuclear Information System (INIS)

    Schwirten, D.

    1994-01-01

    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.

    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.

  13. 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)

  14. On sustainable development of uranium mining industry in China based on the concept of ecological security

    International Nuclear Information System (INIS)

    Wu Shali; Tai Kaixuan

    2011-01-01

    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.

  15. 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

    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

  19. 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.

    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.

    Full Text Available The aim of this article is to highlight the improving performances of entities from mining industry entities by using cost controlling as an important tool of management accounting, applying the target costing method. The survey is based on questions that led investigation made in the Romanian entities from mining industry and based on data a thorough analysis was done for fulfillment of authors’ purpose. The results obtained by applying the target costing method has allowed a very strict cost control, which ultimately led to increased performances of economic entities from mining industry in Romania. The secondary purpose of this article is to try adjusting the target costing method to the specific of entities in the mining industry. According to studies of specialists this method based on target costing calculation is rather unusual in this sector of mining industry and it relies heavily on the activity-based costing method. The article ends with the authors' conclusions on improving the performances of entities from mining industry based on cost controlling and use of mix information obtained through the applied methods

    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.

    2018-06-01

    South Africa has one of the highest HIV prevalences in the world, and compared with other sectors of the national economy, the construction industry is disproportionately adversely affected. Using data collected nationally from more than 57,000 construction workers, HIV infection among South African construction workers was estimated, together with an assessment of the association between worker HIV serostatus and worker characteristics of gender, age, nature of employment, occupation, and HIV testing history. The HIV infection of construction workers was estimated to be lower than that found in a smaller 2008 sample. All worker characteristics are significantly associated with HIV serostatus. In terms of most at-risk categories: females are more at risk of HIV infection than males; workers in the 30-49 year old age group are more at risk than other age groups; workers employed on a less permanent basis are more at risk; as are workers not having recently tested for HIV. Among occupations in the construction industry, general workers, artisans, and operator/drivers are those most at risk. Besides yielding more up-to-date estimated infection statistics, this research also identifies vulnerable sub-groups as valuable pointers for more targeted workplace interventions by construction firms.

    Full Text Available Speaking of mining and sustainability sounds contradictory, as the environmental impact generated by resource extraction is well known. However, there are mining companies that are working to be safe and environmentally friendly. An example of this is presented in this study aimed at identifying occupational risks generated by the activities of a small-scale gold and silver mine located in northwestern Mexico. The methodology followed was a Sustainable Production Program (SPP based on a continuous cycle of five steps in which the tools of cleaner production and pollution prevention are adapted. As a result of this project, it was possible to implement SPP activities: training for workers, use of personal protective equipment and adequate handling of chemicals. As a conclusion, it was verified that SPP application helped this mining company move towards sustainable patterns of production.

    Energy Technology Data Exchange (ETDEWEB)

    Paelke, J.W.

    1988-06-01

    Mining and quarrying companies are seeking improved and more continuous transport methods to reduce their costs. Frequently in the past the use of conveyors has been ruled out in steep mining applications but now the Scholtz FLEXOWELL belting which can be used at angles up to the vertical will enable many mines to consider complete belt conveyor systems for the first time. Applications will include steep conveyors for surface mines and quarries in order to eliminate the need for expensive and noisy fleets of trucks and the associated requirements to maintain haul roads. A further field is in the use of steep or vertical conveyors in underground mines to ensure improved continuity of output in existing shaft systems or reduced development costs in new mines. The Scholtz company, a member of the Nokia Group which had sales of about 3.5 billion U.S. Dollars in 1987, has more than 20 years experience with their FLEXOWELL belts. Over 40,000 units are operating around the world. These are already fully proven for vertical lifts of over 100 m (328ft) and up to 500 m (1,640 ft) is possible. Tonnage ratings of up to 4,000 t/h are achievable. Widespread acceptance of this technology has resulted in unique and major installations over the past few years. This paper reviews various applications - from the viewpoint of successfully proven vertical lift systems as well as the maintenance and downtime aspects. 3 refs., 9 figs.

    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

  15. Genomic sovereignty and the African promise: mining the African genome for the benefit of Africa.

    Science.gov (United States)

    de Vries, Jantina; Pepper, Michael

    2012-08-01

    Scientific interest in genomics in Africa is on the rise with a number of funding initiatives aimed specifically at supporting research in this area. Genomics research on material of African origin raises a number of important ethical issues. A prominent concern relates to sample export, which is increasingly seen by researchers and ethics committees across the continent as being problematic. The concept of genomic sovereignty proposes that unique patterns of genomic variation can be found in human populations, and that these are commercially, scientifically or symbolically valuable and in need of protection against exploitation. Although it is appealing as a response to increasing concerns regarding sample export, there are a number of important conceptual problems relating to the term. It is not clear, for instance, whether it is appropriate that ownership over human genomic samples should rest with national governments. Furthermore, ethnic groups in Africa are frequently spread across multiple nation states, and protection offered in one state may not prevent researchers from accessing the same group elsewhere. Lastly, scientific evidence suggests that the assumption that genomic data is unique for population groups is false. Although the frequency with which particular variants are found can differ between groups, such genes or variants per se are not unique to any population group. In this paper, the authors describe these concerns in detail and argue that the concept of genomic sovereignty alone may not be adequate to protect the genetic resources of people of African descent.

    1995-01-01

    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

    2017-01-02

    The wastewater at Sukinda chromite mines (SCM) area of Orissa (India) showed high levels of toxic hexavalent chromium (Cr VI). Wastewater from chromium-contaminated mines exhibit potential threats for biotic community in the vicinity. The aim of the present investigation is to develop a suitable phytoremediation technology for the effective removal of toxic hexavalent chromium from mines wastewater. A water hyacinth species Eichhornia crassipes was chosen to remediate the problem of Cr (VI) pollution from wastewater. It has been observed that this plant was able to remove 99.5% Cr (VI) of the processed water of SCM in 15 days.

    ABSTRACT The wastewater at Sukinda chromite mines (SCM) area of Orissa (India) showed high levels of toxic hexavalent chromium (Cr VI). Wastewater from chromium-contaminated mines exhibit potential threats for biotic community in the vicinity. The aim of the present investigation is to develop a suitable phytoremediation technology for the effective removal of toxic hexavalent chromium from mines wastewater. A water hyacinth species Eichhornia crassipes was chosen to remediate the problem of Cr (VI) pollution from wastewater. It has been observed that this plant was able to remove 99.5% Cr (VI) of the processed water of SCM in 15 days. This aquatic plant not only removed hexavalent Cr, but is also capable of reducing total dissolved solids (TDS), biological oxygen demand (BOD), chemical oxygen demand (COD), and other elements of water also. Large-scale experiment was also performed using 100 L of water from SCM and the same removal efficiency was achieved. PMID:27551860

    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.

    A computer program is described that estimates the amount of uranium that will be produced from a mine as a co-product of gold subject to a changing economic environment. The program makes use of two models. The first simulates activities underground, whereas the second simulates the performance of processing plant on the surface. The combination of these models generates a description of the flow of ore from stopes and from development, through hoisting, sorting, and the metallurgical plant to the despatch of saleable product. The total production of uranium to the end of the life of the mine constitutes the uranium reserve. The effects on production forecasts and reserve estimates of future trends in cost and price factors are illustrated by results generated from the application of the program to a typical South African mine producing gold and uranium. The graphs presented show that South Africa's future uranium production from underground sources is critically dependent on the gold price in the years ahead. (author)

    Clayey soil found in coal mines in Appalachian Ohio is often sold to landfills for constructing Recompacted Soil Liners (RSL) in landfills. Since clayey soils possess low hydraulic conductivity, the suitability of mined clay for RSL in Ohio is first assessed by determining its clay content. When soil samples are tested in a laboratory, the same engineering properties are typically expected for the soils originated from the same source, provided that the testing techniques applied are standard, but mined clay from Appalachian Ohio has shown drastic differences in particle size distribution depending on the sampling and/or laboratory processing methods. Sometimes more than a 10 percent decrease in the clay content is observed in the samples collected at the stockpiles, compared to those collected through reverse circulation drilling. This discrepancy poses a challenge to geotechnical engineers who work on the prequalification process of RSL material as it can result in misleading estimates of the hydraulic conductivity of the samples. This paper describes a laboratory investigation conducted on mined clay from Appalachian Ohio to determine how and why the standard sampling and/or processing methods can affect the grain-size distributions. The variation in the clay content was determined to be due to heavy concentrations of shale fragments in the clayey soils. It was also concluded that, in order to obtain reliable grain size distributions from the samples collected at a stockpile of mined clay, the material needs to be processed using a soil grinder. Otherwise, the samples should be collected through drilling.

    An European Union consultancy project was undertaken to install a `best-in-class` maintenance system for the lignite mines of Romania. The project, funded by PHARE, started with a critical analysis of the maintenance and repair systems of equipment in both the open-pit and underground mines operated by RALO (Regia Autonoma a Lignitului Octenia). This study paved the way for the introduction of a computerised maintenance system and the inception of a planned preventative maintenance scheme. A development strategy leading by a structural methodology towards predictive maintenance and total productive maintenance was drawn up and attention was given to multi-skilling, training and further facilitating activities to enable the success of the total productive maintenance strategy. An abridged version of the paper was presented at MAINTE 97, held in Birmingham, UK in 1997. 5 refs., 5 figs., 1 tab.

    Conservation of energy is a national agenda as had been set by our Prime Minister at various fora, in the case of coal mining also there is ample scope to reduce specific energy conservation. The issue can be resolved through 'energy audit' so as to identify the areas of improvement, technology to introduce and innovative system to adopt. In a nutshell it can be concluded that, through energy audit, we can immediately save 10-15 % of energy without any major investment

    To evaluate cancer incidence among Minnesota taconite mining workers. We evaluated cancer incidence between 1988 and 2010 in a cohort of 40,720 Minnesota taconite mining workers used between 1937 and 1983. Standardized incidence ratios (SIRs) with 95% confidence intervals (CIs) were estimated by comparing numbers of incident cancers with frequencies in the Minnesota Cancer Surveillance System. SIRs for lung cancer by histologic subtypes were also estimated. We adjusted for out-of-state migration and conducted a probabilistic bias analysis for smoking-related cancers. A total of 5700 cancers were identified, including 51 mesotheliomas and 973 lung cancers. The SIRs for lung cancer and mesothelioma were 1.3 (95% CI = 1.2-1.4) and 2.4 (95% CI = 1.8-3.2), respectively. Stomach, laryngeal, and bladder cancers were also elevated. However, adjusting for potential confounding by smoking attenuated the estimates for lung (SIR = 1.1, 95% CI = 1.0-1.3), laryngeal (SIR = 1.2, 95% CI = 0.8-1.6), oral (SIR = 0.9, 95% CI = 0.7-1.2), and bladder cancers (SIR = 1.0, 95% CI = 0.8-1.1). Taconite workers may have an increased risk for certain cancers. Lifestyle and work-related factors may play a role in elevated morbidity. The extent to which mining-related exposures contribute to disease burden is being investigated. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available In the article, the need of transition to the rational subsoil use (the alternative mining approach is proved, which unlike general one supposes the increasing of extraction rate of valuable components in the deposit and multiple use of raw materials, the maximizing recycling, the decreasing of land occupation, the increasing of the development period of deposit at some income decrease up to the moderate level, which is enough to provide the attraction for investors. The multicriteriality is considered as the crucial principle of rational subsoil use at taking management decisions, i.e. the considering of ecological, economic and social targets, aimed at receiving moderate profit at proper social and environmental standards. The graphic representation of models of the general mining approach and the alternative one allows to emphasize the specified advantages of transition to rational subsoil resources development and reflect them in design equation. In the paper, three performance strategies providing the implementation of the alternative approach are offered: full-field development, application ecologically and economically effective systems and the development processes, consideration of reclamation and minimization of long term environmental effects of mining

    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.

    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

    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.

    1982-01-01

    The technique of delineating coal seams by the use of natural gamma borehole logging sondes has been known for many years. The principle of the technique is that the gamma fluxes in shales are higher than in coals as the abundance of naturally occurring radionuclides is some twenty times greater in the former. This paper discusses other applications where the differeing natural gamma properties of coals and shales can be used. These are: (a) To distinguish between stone (shale) and run-of-mine coal on conveyor belts. A common situation underground is one in which stone from development headings and normal run-of-mine coal have to be batched along the same conveyor system. A natural gamma device capable of distinguishing between such batches of material, and thus allowing suitable mechanical separation, will be described. (b) To provide an accurate measurement of roof coal thickness by measuring the natural gamma flux penetrating the roof coal. To illustrate this examples will be given where this technique is used to provide automatic controlled steering of Long Wall Shearers and to provide manually assisted steering of In-seam Heading Machines

    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.

    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

    The intensive exploitation in the mining district of Cartagena la Union during recent centuries has generated a huge amount of waste scattered throughout the Sierra Minera. These debris act a dangerous pollution agent in the drainage network because the generated runoff erodes and disperse these wastes that are highly contaminated by heavy metals. In this way, the drainage networks of the study area been characterized to assess the production of runoff in basins which are sterile deposits, using the method of the Geomorphologic Unit Hydrography (GUH). The peak flows that have been obtained, taking into account the erodibility of soils, are capable of carrying large amounts of pollutants into the two main outlet areas (Mar Menor and Mediterranean Sea), meaning an important source of pollution int two sites of high ecological value.

    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 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.

  3. The role of conflict minerals, artisanal mining, and informal trading networks in African intrastate and regional conflicts

    Chirico, Peter G.; Malpeli, Katherine C.

    2014-01-01

    The relationship between natural resources and armed conflict gained public and political attention in the 1990s, when it became evident that the mining and trading of diamonds were connected with brutal rebellions in several African nations. Easily extracted resources such as alluvial diamonds and gold have been and continue to be exploited by rebel groups to fund their activities. Artisanal and small-scale miners operating under a quasi-legal status often mine these mineral deposits. While many African countries have legalized artisanal mining and established flow chains through which production is intended to travel, informal trading networks frequently emerge in which miners seek to evade taxes and fees by selling to unauthorized buyers. These networks have the potential to become international in scope, with actors operating in multiple countries. The lack of government control over the artisanal mining sector and the prominence of informal trade networks can have severe social, political, and economic consequences. In the past, mineral extraction fuelled violent civil wars in Sierra Leone, Liberia, and Angola, and it continues to do so today in several other countries. The significant influence of the informal network that surrounds artisanal mining is therefore an important security concern that can extend across borders and have far-reaching impacts.

    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.

    The mining and milling of ores with significant amounts of uranium and thorium associated to the main ore has the potential to pose undue health risks to members of the general public and workers. In order to assess the status of this problem in the Brazilian non-uranium mining industries a comprehensive investigation project has been undertaken. The adopted methodology was based on the detailed analysis of each investigated industry operational flowplan, mass balance calculations, risk assessment (operational and post-operational scenarios taken into account) and environmental management principles. This papers addresses the main issues arising from the investigation effort, reports the most relevant conclusions and states the future studies to be implemented. It could be observed that these industries have the potential to cause relevant radiological impacts and must be regulated/controlled as to avoid these problems. (author)

    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.

    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.

    Full Text Available The timeshare industry is one of most under-researched aspects of tourism accommodation. Within existing scholarship most writings pertain to industry development and challenges in the USA and Europe. This paper provides an examination of the evolution and consolidation of the timeshare industry in South Africa from the 1980s to the present-day. The South African timeshare industry is revealed as one of the most mature in the international timeshare economy. Historically, the industry confronted parallel challenges to those in developed countries in respect of adapting the product to local conditions and confronting a tarnished image from the impact of unscrupulous developers. Currently the South African timeshare sector faces different challenges including service management and consumer dissatisfaction, marginalization within the tourism economy, and the need to address the emerging Black middle class market.

In terms of opportunities, existing potential for export has received the highest priority followed by easy access to national transportation and government support. On the threats part, firm’s dependency on importing necessary parts, global price reduction and mineral reserve termination in near future are the most important issues. In addition, in terms of internal factors, on the opportunity part, access to necessary utilities is considered as the most important factor followed by availability of high level lab equipment and sufficient assets and equities. On the threats, depreciation is considered as the most important issue followed by lack of optimum utilization of equipment and lack of enterprise resource planning. In addition, the study uses balanced score card (BSC technique to look at the performance of the firm in terms of learning and growth, internal process, customer and financials.

    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

    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.

    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.

    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

  17. 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

    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.

    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

    ENGLISH ABSTRACT: The current development of the rapid prototyping industry in South Africa is characterised by the strong dominance and fast growth in sales of three dimensional printers. Although it reflects the international trend, it seems that the industrial community lacks a clear appreciation of the real strength of this technology, especially with respect to the large variety of devices available today on the market. This paper surveys the current state and capabilities of three dimensional printing (3DP. Based on its technical background – the ink-jet printing known from the printer and plotter industry – a classification structure is developed and proposed. Different printing techniques and process concepts, together with their advantages and limitations, are described and analysed. Typical examples from three completely different application areas – manufacturing, medicine, and architecture – are presented and discussed. Some basic considerations for an informed selection of the right technology for a particular application are then presented.

    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.

    Full Text Available Background: Many industries, including the mobile phone industry, experience a surge in supply chain (SC costs in the provision of products and services to their customers. Despite this, only a few studies have been conducted on SC cost reduction in South Africa and globally. Objective: This study seeks to understand the perceptions of managers regarding cost reduction in the South African mobile phone SC. Method: A qualitative case study was conducted, involving eight willing managers and using semi-structured interviews, observation and documents. Interviews transcripts were analysed thematically with the help of Atlas.ti and a threefold process was followed, comprising data reduction, data display and data interpretation and conclusion drawing. Results: The findings suggest that mobile phone companies should consolidate their strategic relationships and be efficient, in order to effectively reduce costs in the South African mobile phone SC. To achieve this, whilst South African mobile network operators have to share more and more infrastructure and outsource their operations, other mobile phone companies should re-engineer their operational processes and their reduce costs across the SC. Conclusion: The knowledge generated from this study should assist South African mobile phone companies to reduce their SC costs and address high-priced mobile services. On the other hand, this study should assist regulating authorities (the Department of Communications and the Independent Communication Authority of South Africa to gain insights into the challenges faced by the mobile phone industry in South Africa and, therefore, to make appropriate and adequate mobile telecommunication policies.

    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.

To obtain a geochemical characterisation of the soil, 31 trace elements were analysed and 669 soil samples were collected. By means of clustering analysis, we identified groups of elements and grid squares in which relations could be established concerning soil lithology, urban and industrial activities and the degree of pollution impact; in addition, we were able to characterise the geochemical background of the study area. The multivariate study led us to identify four factors. Particularly important was factor 2, which represented the elements associated with mineral paragenesis (Cu, Pb, As, Co, Mn, Zn, Sn, Ba). This factor also contains elements related with an urban-industrial activity, such as Pb, Cu, Zn, As and Ba. Furthermore, we identified factor 4, associating Ni, V and Cr, and which is related to the use of fuels.

    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.

    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.

    Full Text Available Opinion mining is an interesting area of research because of its applications in various fields. Collecting opinions of people about products and about social and political events and problems through the Web is becoming increasingly popular every day. The opinions of users are helpful for the public and for stakeholders when making certain decisions. Opinion mining is a way to retrieve information through search engines, Web blogs and social networks. Because of the huge number of reviews in the form of unstructured text, it is impossible to summarize the information manually. Accordingly, efficient computational methods are needed for mining and summarizing the reviews from corpuses and Web documents. This study presents a systematic literature survey regarding the computational techniques, models and algorithms for mining opinion components from unstructured reviews.

    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.

    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

  8. 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

    2008-07-01

    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

    2017-03-01

    Aim: The purpose of this study is to explore supply chain costs in the South African mobile phone industry, and to develop a supply chain cost-reduction framework for the South African mobile phone industry. Setting: This study explores supply chain costs in four mobile phone companies operating in the South African mobile phone industry, of which three mobile network operators and one mobile retailing group. It uses semi-structured interview data collected in 2011. Method: This study adopted a qualitative case study design to understand supply chain costs and develop a supply chain cost-reduction framework for the South African mobile phone industry. Eight semi-structured interviews with managers of mobile phone companies were conducted. The data were analysed with the help of Atlas.ti, using an adapted three-phased analytical framework as suggested by Miles and Huberman (1994 and O’ Dwyer (2004. Results: The study found that consolidation of strategic relationships through collaboration and strategic alliances between MNOs and other supply chain players is one of the ways to drive costs down across the supply chain. Outsourcing of some of the support activities and retailers’ direct purchasing transactions from device manufacturers were also found to be other avenues for reducing supply chain costs in the industry. Conclusion: The study suggests that mobile network operators (MNOs need to consolidate their strategic relationships by increasing the share of the network infrastructure, and emphasising the need to strive for operational efficiencies. This combined effort should result in significant cost reductions across the supply chain. The findings of this study provided some avenues that managers of mobile-phone companies could consider to drive costs down supply chain-wide and service end-users at lower rates. The findings of this study could also help regulating authorities to get insights into supply chain cost reduction and develop appropriate

    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

    2014-11-01

    Research purpose: The purpose of this research was to determine whether there is a relationship between intrinsic rewards and work engagement in the South African retail industry. Furthermore, it sought to validate an instrument to measure intrinsic rewards within the South African context. Motivation for the study: There is currently a paucity of research exploring intrinsic rewards, specifically their importance for work engagement. Furthermore, there is a lack of instruments validated in South Africa that can be used to measure intrinsic rewards. Research approach, design and method: This quantitative study was conducted using a cross-sectional design and non-probability sampling of 181 employees from a South African retail organisation. The questionnaire included a demographic section, the Utrecht Work Engagement Scale and the Work Engagement Profile. Main findings: Statistically significant, positive relationships were found between all subscales of the two instruments. There were significant differences in the means for intrinsic rewards and work engagement for gender and age. Notably, the exploratory factor analysis for both instruments did not support the factor structure indicated in the literature. Practical/managerial implications: South African retail organisations should create work environments that provide intrinsic rewards as part of their reward package, to encourage work engagement. Contribution/value-add: These findings add to the current body of literature regarding intrinsic rewards and work engagement and provide insight into variables that promote work engagement within the South African retail context.

    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.)

  19. Metal mining to the aid of the oil sands? Lateral opportunities in industrial cross-breeding

    Energy Technology Data Exchange (ETDEWEB)

    Sabag, S.F. [Dumont Nickel Inc., Toronto, ON (Canada)

    2009-07-01

    This paper demonstrated how oil sands operations can benefit from supporting innovative low cost metal mining to enhance their eco-footprint. Northeast Alberta contains large accumulations of recoverable metals, hosted in metal bearing black shales. Immense low grade polymetallic zones were discovered in 1995 but could not be exploited with existing recovery technologies. However, significant advances in bioleaching of metals from polymetallic black shale deposits have propelled this new deposit type to the forefront over the past 5 years as a long term future source of metals. Compared to traditional smelting and refining, bioleaching has lower Capex/Opex, lower eco-footprint and less energy dependence. Envisaged metal mining in the black shales of northeast Alberta can benefit oil sands operations by consuming large amounts of waste sulfur while also providing collateral opportunities for carbon sinks/offsets. Black shales have the capacity to sequester carbon dioxide (CO{sub 2}). Dumont Nickel Inc. is advancing 6 polymetallic black shale projects in northeast Alberta over 2,500 km{sup 2} with potential for hosting up to 20 billion tons in six 50-100 km{sup 2} deposits. The projects present opportunities to develop low footprint metal mines, to use run-of-river hydro, to harvest waste heat, and to combine local technologies to create a new valuable industry independent of energy markets.

  20. 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.

    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.

    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)

    Full Text Available Background: The construction industry in South Africa has a lot of potential but its performance is still restricted by numerous internal and external challenges. Unless these challenges are identified and understood better, further growth of this industry is likely to be hindered, which has negative economic implications for the South African economy. Objectives: This study investigated supply chain bottlenecks faced by the construction industry in South Africa. It also discussed solutions for addressing the identified bottlenecks in order to facilitate the continued development of supply chain management in the construction industry. Method: The study used a qualitative approach in which in-depth interviews were held with purposively selected senior managers drawn from the construction industry in South Africa. Content analysis using ATLAS.ti software was employed to identify the themes from the collected data. Findings: The findings of the study showed that supply chain management in the construction industry in South Africa is constrained by five major bottlenecks: skills and qualifications, procurement practices and systems, supply chain integration, supply chain relationships and the structure of the construction industry. Recommendations for addressing each of these five challenges were put forward. Conclusion: The study concludes that both awareness and application of supply chain management in the construction industry in South Africa remains inhibited, which creates opportunities for further improvements in this area to realise the full potential of the industry.

    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

    Full Text Available Material transportation by belt conveyers is widely used in many industrial branches including mining plants. Belt conveyingdevelopment during the last year was oriented mainly on construction of belts. The consequence of this is the improvement of itsmanufacture qualities bringing down the costs for their exchange and maintenance.Despite the fact that there are some theoreticalcalculations based on a standards it is common in the industry that the belt is not properly selected or it is overdesigned or number of itstypes is too large what can lead to increased costs for its storage. The paper describes the optimization of number of belt types in miningcompany SIDERIT, s. r. o.

    Glombitza, Franz; Reichel, Susan

    2014-01-01

    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.

    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.

    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.

    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.

    The author has identified the following significant results. New fracture detail of Indiana has been observed and mapped from ERTS-1 imagery. Studies so far indicate a close relationship between the directions of fracture traces mapped from the imagery, fractures measured on bedrock outcrops, and fractures measured in the underground mines. First hand observations and discussions with underground mine operators indicate good correlation of mine hazard maps prepared from ERTS-1/aircraft imagery and actual roof falls. The inventory of refuse piles/slurry ponds of the coal field of Indiana has identified over 225 such sites from past mining operations. These data will serve the State Legislature in making tax decisions on coal mining which take on increased importance because of the energy crisis.

    Du Randt, Francois Jean

    2014-08-01

    Full Text Available Projects that fail, for whatever reason, can impact negatively on society, organisations, and other stakeholders. A number of researchers have identified various critical success factors (CSFs that can influence the outcome and success of a project. This research therefore aims to determine the CSFs that influence various success measures of small- to medium-sized projects at a South African mining company, Exxaro Resources’ Grootegeluk Coal Mine. Other objectives of this research include determining the extent of the impacts of these CSFs on the different success measures of a project. The investigation suggests that there are correlations among CSFs, and that certain factors impact the outcome of projects far more than others. This research finds that the single most important CSF for small- to medium-sized projects is the selection of a competent project manager. The competent project manager is characterised by a group of interrelated CSF factors: good leadership, commitment, and learning from past experiences. Based on the research results, other CSFs are discussed and explored in order for recommendations to be made on how this mining company, and possibly other organisations, can achieve greater project success.

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

    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.

    Sackey, Samuel Mensah

    2016-12-01

    Full Text Available With its potential to change significantly the knowledge and skill-set requirements for industrial engineers (IEs, Industry 4.0 creates a need to reassess the place of IEs to avoid a greater shock than that caused by the information technology identity crisis of the 1990s. This article examines the likely impacts of Industry 4.0 on industrial engineering (IE and proposes enhancements to IE curricula in South Africa. Research methods include a literature review, a study of IE curricula, and a questionnaire survey of IE programmes. Results indicate that several IE functions might become somewhat transformed, less visible, or downright diminished in Industry 4.0. Emphasis has shifted from traditional IE methods to data-driven functions and cyber-physical systems. The developing mismatch needs correcting by emphasising skills such as ‘big data’ analytics and novel human-machine interfaces in IE curricula. Only one university in South Africa has made progress towards the adoption of an Industry 4.0 infrastructure. The authors propose a set of curriculum enrichment items as the basis for reform.

    1999-10-07

    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.) [German] Der Beitrag fasst die wesentlichen Ergebnisse einer wissenschaftlichen Studie zusammen: Die Unfallentwicklung im deutschen Bergbau zeigt im Vergleich zu anderen Industriezweigen noch deutliche Reserven fuer die Praevention. Die Fortentwicklung der Sicherheitstechnik fuer sich allein liefert aber nur noch abnehmende Grenzertraege. Eine Strategie technischer und organisatorischer Einzeldirektiven reicht ebenfalls nicht aus. Der Weg zu besseren Sicherheitsresultaten im Bergbau fuehrt vor allem ueber optimierte Ablaeufe des Sicherheitsmanagements. Mit verschiedenen Methoden lassen sich Aufbau- und Ablauforganisation der Arbeitssicherheit auf ihre Effizienz untersuchen. Aus der juristisch implizierten und organisatorisch zweckmaessigen Aufgabenteilung zwischen Fuehrungskraeften und Sicherheitsexperten ergeben sich Zurodnungsmuster fuer sicherheitsrelevante Aufgaben.

    Jeffrey I Rose

    Full Text Available Despite the numerous studies proposing early human population expansions from Africa into Arabia during the Late Pleistocene, no archaeological sites have yet been discovered in Arabia that resemble a specific African industry, which would indicate demographic exchange across the Red Sea. Here we report the discovery of a buried site and more than 100 new surface scatters in the Dhofar region of Oman belonging to a regionally-specific African lithic industry--the late Nubian Complex--known previously only from the northeast and Horn of Africa during Marine Isotope Stage 5, ∼128,000 to 74,000 years ago. Two optically stimulated luminescence age estimates from the open-air site of Aybut Al Auwal in Oman place the Arabian Nubian Complex at ∼106,000 years ago, providing archaeological evidence for the presence of a distinct northeast African Middle Stone Age technocomplex in southern Arabia sometime in the first half of Marine Isotope Stage 5.

    2009-12-01

    Full Text Available Purpose: This article explores the possibility of developing a distribution model, similar to the model developed and implemented by the South African pharmaceutical industry, which could be implemented by automotive component manufacturers for supply to independent retailers. Problem Investigated: The South African automotive components distribution chain is extensive with a number of players of varying sizes, from the larger spares distribution groups to a number of independent retailers. Distributing to the smaller independent retailers is costly for the automotive component manufacturers. Methodology: This study is based on a preliminary study of an explorative nature. Interviews were conducted with a senior staff member from a leading automotive component manufacturer in KwaZulu Natal and nine participants at a senior management level at five of their main customers (aftermarket retailers. Findings: The findings from the empirical study suggest that the aftermarket component industry is mature with the role players well established. The distribution chain to the independent retailer is expensive in terms of transaction and distribution costs for the automotive component manufacturer. A proposed centralised distribution model for supply to independent retailers has been developed which should reduce distribution costs for the automotive component manufacturer in terms of (1 the lowest possible freight rate; (2 timely and controlled delivery; and (3 reduced congestion at the customer's receiving dock. Originality: This research is original in that it explores the possibility of implementing a centralised distribution model for independent retailers in the automotive component industry. Furthermore, there is a dearth of published research on the South African automotive component industry particularly addressing distribution issues. Conclusion: The distribution model as suggested is a practical one and should deliver added value to automotive

    The alcohol beverage industry has been expanding its corporate social responsibility and other business activities in sub-Saharan Africa. The aim of this paper is to evaluate the effects of these activities on the physical, economic, psychological and social availability of alcohol in the region. Narrative review. Source materials came from the business press, industry sources (websites, annual reports, press releases, conference proceedings) and the scientific literature published since 2000. The alcohol industry has intensified its activities in the African region, through their funding of social aspect organizations, technical publications, policy workshops and other corporate social responsibility activities. Marketing campaigns, new product designs and the development of industry-civil society partnerships have increased. There is evidence that the alcohol industry also engages in lobbying, information dissemination and legal action to thwart effective public health measures. The corporate social responsibility activities of the global alcohol industry have provided a vehicle to promote industry-favorable policies and increase the physical, economic, social and psychological availability of alcohol. © 2015 Society for the Study of Addiction.

    2007-12-01

    Full Text Available Purpose: The purpose of this article is to explore perceptions regarding buyer and supplier collaboration around product development. The aim is to gain an understanding of which factors influence buyer-supplier collaboration outcomes in the South African textile industry. Methodology: This study comprised two data collection stages. The first stage comprised the design and administration of a questionnaire survey. The second stage utilised a qualitative interview methodology and entailed interviewing a subset of the questionnaire respondents in order to probe respondents’ own experiences in collaborative product developments and their perception of the factors that determine collaboration outcome. Findings: This study has shed light on the experiences of South African firms in the textile industry engaging in buyer-supplier collaboration around product development. While this study is exploratory, it has provided evidence that there are certain factors which are perceived to have a significant influence on collaboration. Implications: Under the past protective shield of tariffs, South African clothing and textile manufacturers could afford to allow an adversarial mode of operation to perpetuate inefficiencies. However, the increasing external pressures, including the very real threat of overseas competition, heighten the need for collaboration between buyers and suppliers. This relates, in particular, to collaboration aimed at new product development, which can be seen as a new imperative for the survival and growth of this industry. Currently, there are numerous barriers to effective collaboration. The overwhelming power of retailers in the value chain is one such barrier, as it creates an environment which is pressurised, strained and not conducive to buyer-supplier collaboration. Contribution and Value: Studies on collaborative new product development have primarily been done in developed countries, with a focus on technology intensive

  14. Conceptual model for decision support in mining industry NORM - aspects of environmental radiation protection

    Reis, Rocio Gloria dos

    2012-01-01

    Mining like many other industries can cause environmental impact. One of aspects that is in focus in many countries concerns to quantify the impact and establish requirements or improve the existing regulation about naturally occurring radioactive material - NORM. By a suitable management of the activities in these industries, there is an effort to minimize the waste production, minimize the environmental impacts and, consequently, the exposure of members of the public and workers. This study developed a conceptual model, a tool to assist in the decision making process for managers of mining and industrial facilities that deal with NORM. To develop this model, the Brazilian regulations were confronted with the regulations of countries where the NORM subject is important and with those that are being established by the principal institutions of radioprotection. The need of updating the Brazilian regulations was observed. Some recurring themes that are relevant to the management of NORM industries were surveyed, which resulted in the insertion of non-human biota risk assessment and the participation of stakeholders in the proposed model. The model was applied to a real case, the phosphoric acid and uranium plant of Santa Quiteria, in the Ceara state, with the aim of identifying the main critical points of the facility from the perspective of the environmental radiological impact and evaluating the adequacy of model, in addition to providing subsidies for its improvement. By the assessment of the process, it was found that the main source would be the phosphogypsum stack, which "2"2"6Ra activity concentration might exceed the level established for its use in agriculture and cement industry. The impact assessment was carried out in three different scenarios: 1) the critical group located in the facility borders, 2) the critical group located on the stack, after the closure of the area and 3) workers. In all cases, the exercise pointed out the exceeding of the adopted

  15. Derived surface contamination limits for the uranium mining and milling industry

    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

    2015-06-01

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

    Full Text Available The mining industry in South Africa contributes significantly to its economy. Training is an important component in these environments and e-Learning is often used to train the large workforce. In the face of current labour unrest and job cuts in this sector, it is foreseen that e-Learning might play an increasing important role to upskill the remaining work force. However, it appears that low motivation and resistance to e-Learning exist amongst learners. The aim of this research was to examine the factors that may contribute to this resistance and/or adoption from the perspectives of e-Learning managers and practitioners. Activity theory was used as the theoretical lens and its main elements (tools, subjects, rules, objects, community were used to analyse interviews with participants from two mining companies. Potential contradictions were identified in order to explore resistance to e-Learning. The main findings indicate that: 1 proper communication of expectations by different stakeholders of e-Learning is imperative, 2 top management support for e-Learning should stem from integration into the organisational goals, 3 more attention should be given to interaction between learners and facilitators and also between learners, 4 a focus on people development rather than only compliance may lead to lower resistance, and 5 top management support and involvement should be made visible.

    This study seeks to examine the relationship and impact of occupational health and safety on employees' organizational commitment in Ghana's mining industry. The study explores occupational health and safety and the different dimensions of organizational commitment. A cross-sectional survey design was used for this study. The respondents were selected based on simple random sampling. Out of 400 questionnaires administered, 370 were returned (77.3% male and 22.7% female) and used for the study. Correlation and multiple regression analysis were used to determine the relationship and impact between the variables. The findings of this study revealed positive and significant relationship between occupational health and safety management, and affective, normative, and continuance commitment. Additionally, the results revealed the significant impact of occupational health and safety on affective, normative, and continuance commitment. Management within the mining sector of Ghana must recognize the fact that workers who feel healthy and safe in the performance of their duties, develop emotional attachment and have a sense of obligation to their organization and are most likely committed to the organization. Employees do not just become committed to the organization; rather, they expect management to first think about their health and safety needs by instituting good and sound policy measures. Thus, management should invest in the protection of employees' health and safety in organizations.

    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.

    2014-12-01

    Full Text Available This paper deals with the historical dimension of the economic and social space of Tlalpujahua and El Oro Mining District from the perspective of the Industrial Heritage. The exploration and exploitation in search for precious minerals along the sixteenth to the twentieth centuries articulated a culture of wage labour and facilitated the circulation of new knowledge, technical expertise and an impressive technological innovation in the late nineteenth and early twentieth centuries. With the depletion of gold and silver in the mid-twentieth century, the socio-technical framework disappears but not the memory and industrial vestiges which represents long-term historical processes, and as a social laboratory allows to recognize and analyze the changes in the social relations of different human groups, different nationality and social status — workers, technicians, engineers, businessmen, traders, etc. —, who moved to the minerals in the quest to materialise their own life expectancy. The study and appreciation of the historical and cultural experience ensures the memory of the industrial heritage of Mexicans.

    Since the gradual decrease of mineral resources on-land, deep sea mining (DSM) is becoming an urgent and important emerging activity in the world. However, until now there has been no commercial scale DSM project in progress. Together with the reasons of technological feasibility and economic profitability, the environmental impact is one of the major parameters hindering its industrialization. Most of the DSM environmental impact research focuses on only one particular aspect ignoring that all the DSM environmental impacts are related to each other. The objective of this work is to propose a framework for the numerical calculation methods of the integrated DSM environmental impacts through a literature review. This paper covers three parts: (i) definition and importance description of different DSM environmental impacts; (ii) description of the existing numerical calculation methods for different environmental impacts; (iii) selection of a numerical calculation method based on the selected criteria. The research conducted in this paper provides a clear numerical calculation framework for DSM environmental impact and could be helpful to speed up the industrialization process of the DSM industry.

    Full Text Available In the paper a dynamic behaviour of the selected typical group of rotating machines applied in the mining industry is investigated. These are the beater mills and crushers as well as blowers and compressors, all driven by the asynchronous motors. In particular, there is considered an influence of various types of machine working tool loadings on the system lateral steady-state dynamic responses as well as a mutual torsional electromechanical interaction between the driving motor and the driven machine in transient operational conditions. The theoretical calculations have been performed by means of the advanced structural mechanical models. The conclusions drawn from computational results can be very useful during design phase of these devices as well as helpful for their users during regular maintenance.

    Metagenomic libraries herald the era of magnifying the microbial world, tapping into the vast metabolic potential of uncultivated microbes, and enhancing the rate of discovery of novel genes and pathways. In this paper, we describe a method that facilitates the extraction of metagenomic DNA from activated sludge of an industrial wastewater treatment plant and its use in mining the metagenome via library construction. The efficiency of this method was demonstrated by the large representation of the bacterial genome in the constructed metagenomic libraries and by the functional clones obtained. The BAC library represented 95.6 times the bacterial genome, while, the pUC library represented 41.7 times the bacterial genome. Twelve clones in the BAC library demonstrated lipolytic activity, while four clones demonstrated dioxygenase activity. Four clones in pUC library tested positive for cellulase activity. This method, using FTA cards, not only can be used for library construction, but can also store the metagenome at room temperature.

    Mining industry is characterized by a high operational revenue, and hence high availability of heavy equipment used in mining industry is a critical factor to ensure the revenue target. To maintain high avaliability of the heavy equipment, the equipment's owner hires an agent to perform maintenance action. Contract is then used to control the relationship between the two parties involved. The traditional contracts such as fixed price, cost plus or penalty based contract studied is unable to push agent's performance to exceed target, and this in turn would lead to a sub-optimal result (revenue). This research deals with designing maintenance contract compensation schemes. The scheme should induce agent to select the highest possible maintenance effort level, thereby pushing agent's performance and achieve maximum utility for both parties involved. Principal agent theory is used as a modeling approach due to its ability to simultaneously modeled owner and agent decision making process. Compensation schemes considered in this research includes fixed price, cost sharing and revenue sharing. The optimal decision is obtained using a numerical method. The results show that if both parties are risk neutral, then there are infinite combination of fixed price, cost sharing and revenue sharing produced the same optimal solution. The combination of fixed price and cost sharing contract results in the optimal solution when the agent is risk averse, while the optimal combination of fixed price and revenue sharing contract is obtained when agent is risk averse. When both parties are risk averse, the optimal compensation scheme is a combination of fixed price, cost sharing and revenue sharing.

  8. Building customer relationships as retention strategy in the South African domestic passenger airline industry

    Full Text Available Organisations are increasingly focusing on building long-term relationships with customers, thereby increasing their probability for success by offering customers higher levels of satisfaction, increasing customer loyalty, and ultimately retaining customers. Airlines in particular can benefit from retaining customers as the airline industry is characterised by fierce competition and many airlines are finding it difficult to survive against the backdrop of enormous challenges in the past decade, including the significant decline in demand for air travel together with rising costs and the worldwide economic downturn. This study investigates the effect which a strategy by airlines of building relationships with customers has on customer satisfaction, loyalty, and ultimately customer retention. The effect of service failures on customers' relationships with airlines are also considered as a negative experience could results in customers defecting to competitors. A questionnaire, comprising six sections, was specifically compiled to determine customer retention in the South African domestic passenger airline industry. Data were collected by trained fieldworkers from OR Tambo International Airport by means of a non-probability convenience sampling method from 324 passengers flying with the various domestic airlines. Findings indicate that most respondents were satisfied with the airlines' overall service; respondents who formed relationships with domestic airlines were more loyal toward the airlines; and the relationships of respondents who were satisfied with airlines' service recovery efforts were either strengthened or unchanged. The findings from this study support findings from international studies by providing a unique South African perspective on the effect of a strategy of building relationships with customers on their satisfaction, loyalty and ultimately retention. It can therefore be recommended that the organisations competing in the South

    Bioleaching mechanism of uranium ore is discussed. Incubation and selection of new strain, biomembrane oxidizing tank--a kind of new equipment for bacteria culture and oxidation regeneration of leaching agent are also introduced. The results of industrial experiment and industrial production are summarized. Compared with conventional heap leaching, bioleaching period and acid amount are reduced, oxidant and leaching agent are saved, and uranium concentration in leaching solution is increased. It is the first time to realize industrial production by bio-heap leaching in Chinese uranium mine. New equipment-biomembrane oxidizing tank give the basis of bio-heap leaching industrial application. Bio-heap leaching process is an effective technique to reform technique of uranium mine and extract massive low-content uranium ore in China. (authors)

    The author has identified the following significant results. The most important result to date is the demonstration of the special value of repetitive ERTS-1 multiband coverage for detecting previously unknown fracture lineaments despite the presence of a deep glacial overburden. The Illinois Basin is largely covered with glacial drift and few rock outcrops are present. A contribution to the geological understanding of Illinois and Indiana has been made. Analysis of ERTS-1 imagery has provided useful information to the State of Indiana concerning the surface mined lands. The contrast between healthy vegetation and bare ground as imaged by Band 7 is sharp and substantial detail can be obtained concerning the extent of disturbed lands, associated water bodies, large haul roads, and extent of mined lands revegetation. Preliminary results of analysis suggest a reasonable correlation between image-detected fractures and mine roof fall accidents for a few areas investigated. ERTS-1 applications to surface mining operations appear probable, but further investigations are required. The likelihood of applying ERTS-1 derived fracture data to improve coal mine safety in the entire Illinois Basin is suggested from studies conducted in Indiana.

    2015-04-01

    To describe the penetration and expansion of the global alcohol industry into the African region, as a context for exploring the implications for public health. Source materials for this study came primarily from market research and the business press. This was supplemented by industry sources (from websites, company annual reports), World Health Organization reports and the scientific literature. Drinking in Africa is characterized by high rates of abstention and a high prevalence of heavy episodic consumption among those who drink. Much of the region is currently experiencing a rapid rise in consumption. Rising populations and income and the rapid pace of urbanization make Africa very attractive to the global alcohol industry, and industry leaders have identified Africa as a key area for growth. The shift from collaboration to competition in Africa among the global alcohol companies has prompted increasing alcohol production, promotion, new product development, pricing schemes and stakeholder lobbying. Beer consumption has increased across most of the continent, and global brewers view themselves as legitimate players at the alcohol policy table. Weak alcohol policy environments may be compromised further in terms of public health protections by alcohol industry opposition to effective measures such as marketing regulations, availability controls and taxation. © 2014 Society for the Study of Addiction.

    Full Text Available Orientation: Lack in congruence amongst industrial and organisational psychologists (IOPs as to the conceptualisation of its profession poses a significant risk as to the relevance, longevity and professional identity of the profession within the South African context. Research purpose: This study aimed to explore the professional identity of IOPs within the South African context. Specifically, the aim of this study was four-fold: (1 to develop a contemporary definition for IOP, (2 to investigate IOP roles, (3 to determine how the profession should be labelled and (4 to differentiate IOP from human resource management (HRM from IOPs’ perspectives within South Africa. Motivation for the study: IOPs do not enjoy the same benefits in stature or status as other professions such as medicine, finances and engineering in the world of work. IOPs need to justify its relevance within organisational contexts as a globally shared understanding of ‘what it is’, ‘what it does’ and ‘what makes it different from other professions’, which is non-existent. In order to enhance its perceived relevance, clarity as to IOPs professional identity is needed. Research design, approach and method: A post-positivistic qualitative content analytic and descriptive research design was employed in this study. Data from practising industrial and organisational psychology (IOP within South Africa (N = 151 were gathered through an electronic web-based survey and were analysed through thematic content analysis. Main findings: The results indicate that IOP in South Africa seeks to optimise the potential of individuals, groups, organisations and the community by implementing scientific processes to support both individual and organisational wellness and sustainability. ‘Work Psychology’ was considered a more fitting professional designation or label than industrial and/or organisational psychology.

    Full Text Available In many modern manufacturing industries, data that characterize the manufacturing process are electronically collected and stored in databases. Due to advances in data collection systems and analysis tools, data mining (DM has widely been applied for quality assessment (QA in manufacturing industries. In DM, the choice of technique to be used in analyzing a dataset and assessing the quality depend on the understanding of the analyst. On the other hand, with the advent of improved and efficient prediction techniques, there is a need for an analyst to know which tool performs better for a particular type of dataset. Although a few review papers have recently been published to discuss DM applications in manufacturing for QA, this paper provides an extensive review to investigate the application of a special DM technique, namely support vector machine (SVM to deal with QA problems. This review provides a comprehensive analysis of the literature from various points of view as DM concepts, data preprocessing, DM applications for each quality task, SVM preliminaries, and application results. Summary tables and figures are also provided besides to the analyses. Finally, conclusions and future research directions are provided.

  3. Valorization of mine rejects and industrial wastes for the recovery of some strategic and critical metals

    Sreenivas, T.; Dey, G K.; Anand Rao, K.

    2017-01-01

    Strategic and critical metals (SCM) resources form important components in safety and security design of any country. Uneven distribution of SCM resources as well as lack of technical expertise in manufacture of end-products makes many nations vulnerable to external pulls and pressures. India is making determined bid to surmount these difficulties by constantly upgrading its scientific and engineering expertise to address issues related to resources and materials manufacturing technologies. It is a well known fact that India is a resource starved country with respect to many of the strategic and critical metals (SCM). The demand for the SCM is met mostly by import of finished products and to a lesser extent by recycle of used products. In these days of growing inclination towards 'sustainable development' valorization of industrial waste for securing valuable metals including those of SCM category is worth pursuing, more so for a country like India. With this premise, we present in this paper representative case studies which depict technical feasibility of using industrial waste as a source for some important SCM, namely Nd, Y, Co and W. The wastes used for valorization are the mine tailings or rejects of different ores like copper, gold, uranium and fly ash generated from a coal-fired thermal power plant. (author)

  4. 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.

  5. Undisclosed chemicals--implications for risk assessment: a case study from the mining industry.

    Singh, Khareen; Oates, Christopher; Plant, Jane; Voulvoulis, Nikolaos

    2014-07-01

    Many of the chemicals used in industry can be hazardous to human health and the environment, and some formulations can have undisclosed ingredients and hazards, increasing the uncertainty of the risks posed by their use. The need for a better understanding of the extent of undisclosed information in chemicals arose from collecting data on the hazards and exposures of chemicals used in typical mining operations (copper, platinum and coal). Four main categories of undisclosed chemicals were defined (incomplete disclosure; chemicals with unspecific identities; relative quantities of ingredients not stated; and trade secret ingredients) by reviewing material safety data sheet (MSDS) omissions in previous studies. A significant number of chemicals (20% of 957 different chemicals) across the three sites had a range of undisclosed information, with majority of the chemicals (39%) having unspecific identities. The majority of undisclosed information was found in commercially available motor oils followed by cleaning products and mechanical maintenance products, as opposed to reagents critical to the main mining processes. All three types of chemicals had trade secrets, unspecific chemical identities and incomplete disclosures. These types of undisclosed information pose a hindrance to a full understanding of the hazards, which is made worse when combined with additional MSDS omissions such as acute toxicity endpoints (LD50) and/or acute aquatic toxicity endpoints (LC50), as well as inadequate hazard classifications of ingredients. The communication of the hazard information in the MSDSs varied according to the chemical type, the manufacturer and the regulations governing the MSDSs. Undisclosed information can undermine occupational health protection, compromise the safety of workers in industry, hinder risk assessment procedures and cause uncertainty about future health. It comes down to the duty of care that industries have towards their employees. With a wide range of

    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.

    Discusses conditions for underground coal mining in Poland, types of equipment for coal cutting, mine haulage and strata control and development trends of mining technologies. In 1985, black coal output was 191.6 Mt; 85.3% came from longwall faces mined by sets of mining equipment (coal cutters, chain conveyors and powered supports). The average coal output per longwall face was 881 t/d, output per face mined by sets for mining equipment was 1,134 t/d. In 1985, 653 shearer loaders and 77 coal plows were used in Polish coal mines. Number of shearer loaders is increasing. Shearer loaders with chainless haulage system were safest and most economic. The shearer loaders were equipped with the POLTRAK chainless haulage system developed in Poland. Research programs concentrate on development of new mining equipment for thin seam mining, steep seam mining, longwall mining with hydraulic stowing, efficient strata control by powered or shield supports under conditions of increased stresses or rock burst hazards. 4 refs.

    Full Text Available The maritime industry is the major enabler of international trade. Major economic events in the international arena such as global recessions affect world trade and therefore the maritime industry as well. South Africa imports and exports major commodities and products therefore such events will also affect the country's economy. This paper explores how different industries within the South African maritime industry have been affected by global economic recessions. As some of them are of great significance to the country's economy, it is imperative to look at how these industries are affected so as to be able to see the national impact.

    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.

    2003-01-01

    A. Richards, a public relations specialist from Cogema Resources Inc., discussed the programmes for human resource and community development in northern Saskatchewan. This region has the world's largest known high-grade deposits of uranium as well as a high level of provincial, public and northern community support. A mainly Aboriginal population of around 35 000 with a very high proportion of young persons entering the work force, lives in small, dispersed communities in a landscape of forest and lakes. All of the uranium mines are in remote locations with 'local impact' communities often several hundred kilometres away. In the late 1970's a public board of inquiry set none operating conditions that included maximizing opportunities for northern business and employment. Dozens of joint initiatives have since been developed and resulted in innovative hiring, training and transportation programmes, as well as support programmes to improve health, education, professional and business development and quality of life in the communities. Residents of northern Saskatchewan, like all other Canadians, are not prepared to accept environmental risks in return for economic opportunities. Three regional Environmental Quality Committees, with representatives froth all of the northern communities, work with Provincial agencies and the uranium mining industry to ensure community concerns are included in decisions. Northern hunters and fishermen, whose close links with the land are respected, provide relevant data to the Environmental Monitoring Program. Mutual trust is developed through constant interaction and dialogue in one-to-one relationships. Traditional activities like trapping are given their full importance. A Community Vitality Project jointly monitors social well being as defined by northern interests and culture. Compensations and company donations in some cases provide resources for community activities. (author)

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

    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.

    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''.

    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.

    2009-07-01

    Metal pollution is viewed as a modern problem that began in the 19th century and accelerated through the 20th century; however, in many parts of the globe this view is wrong. Here, we studied past waterborne metal pollution in lake sediments from the Bergslagen region in central Sweden, one of many historically important mining regions in Europe. With a focus on lead (including isotopes), we trace mining impacts from a local scale, through a 120-km-long river system draining into Mälaren--Sweden's third largest lake, and finally also the Baltic Sea. Comparison of sediment and peat records shows that pollution from Swedish mining was largely waterborne and that atmospheric deposition was dominated by long-range transport from other regions. Swedish ore lead is detectable from the 10th century, but the greatest impact occurred during the 16th-18th centuries with improvements occurring over recent centuries, i.e., historical pollution > modern industrial pollution.

    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)

    Effects of mechanization on underground coal mining in Poland from 1960 to 1980 and mining equipment used in Poland is reviewed. In 1983 black coal output increased to 191.1 Mt. There were 765 working faces, 442 of which with powered supports. Six hundred thirty-four shearer loaders were in use. About 82.7% of coal output fell on faces mined by sets of mining equipment (shearer loaders, powered supports and chain conveyors). The average coal output per working face amounted to 889 t/d. About 50% of mine roadways was driven by heading machines (346 heading machines were in use). The average coal output per face mined by a set of mining equipment amounted to 1248 t/d. About 86% of shearer loaders fell on double drum shearer loaders. Types of mining equipment used in underground mining are reviewed: powered supports (Pioma, Fazos, Glinik and the SOW), shearer loaders (drum shearer loaders and double-drum shearer loaders with chain haulage and chainless haulage systems for unidirectional and bi-directional mining), chain conveyors (Samson, Rybnik). Statistical data on working faces with various sets of equipment are given. 3 references.

    The natural development of the Ústí region (North-West Bohemia, the Czech Republic) has been affected by the human activity during the past hundred years. The heavy industrialization and the brown coal mining have completely changed the land-use in the region. The open-pit coal mines are completely destroying the surrounding landscape, including settlement, communications, hydrological network and the over-all natural development of the region. The other factor affecting the natural development of the landscape, land-use and settlement was the political situation in 1945 (end of the 2nd World War) when the borderland was depopulated. All these factors caused vanishing of more than two hundreds of colonies, villages and towns during this period of time. The task of this project is to prepare and offer for public use a comprehensive information system preserving the cultural heritage in the form of processed old maps, aerial imagery, land-use and georelief reconstructions, local studies, text and photo documents covering the extinct landscape and settlement. Wide range of various maps was used for this area - Müller's map of Bohemia (ca. 1720) followed by the 1st, 2nd and 3rd Military survey of Habsburg empire (1792, 1894, 1938), maps of Stabile cadaster (ca. 1840) and State map derived in the scale 1:5000 (1953, 1972, 1981). All the maps were processed, georeferenced, hand digitized and are further used as base layers for visualization and analysis. The historical aerial imagery was processed in standard ways of photogrammetry and is covering the year 1938, 1953 and the current state. The other important task covered by this project is the georelief reconstruction. We use the old maps and aerial imagery to reconstruct the complete time-line of the georelief development. This time-line is covering the period since 1938 until now. The derived digital terrain models and further on analyzed and printed on a 3D printer. Other reconstruction task are performed using

    Full Text Available Orientation: Workplace incivility holds consequences for both individuals and organisations. Managers are becoming increasingly aware of this phenomenon. Currently, there is no workplace incivility scale validated for use within the South African context. Research purpose: To investigate the reliability and validity of the adapted workplace incivility scale by Leiter and colleagues for use within South Africa. Motivation for the study: As it is currently difficult to measure workplace incivility within the South African context because of the lack of a valid and reliable scale, it is necessary to validate such a scale. Research design, approach and method: A cross-sectional research approach was used for the study. Convenience sampling (N = 345 was used within the South African banking industry. Specifically, the factor structure, convergent validity, discriminant validity and predictive validity were investigated in order to establish the overall validity of the scale. Main findings: The results confirmed that the scale showed a three-factor structure as bestfitting with acceptable reliability coefficients. Furthermore, discriminant validity could be shown between workplace incivility and workplace bullying, that is, supporting that these two constructs are not the same phenomenon. In terms of relationships, colleague incivility did not significantly predict any of the outcome variables and instigated incivility only being a negative predictor of job satisfaction and a borderline statistically significant negative predictor of work engagement. However, supervisor incivility predicted all the outcomes negatively. Practical/Managerial implications: Based on the results, workplace incivility should be addressed because of the harmful effects it can have, not only on employees but also on organisations. It is therefore necessary for managers to create awareness of workplace incivility in order to ensure that it does not integrate within the

  10. A case study of GAMM (graphical analysis for maintenance management) in the mining industry

    2014-01-01

    This paper presents a case for practical application of the GAMM method, which has been developed and published by the authors (Barberá L., Crespo A. and Viveros P.) The GAMM method supports decision-making in the overall maintenance management, through the visualization and graphical analysis of data. In addition, it allows for the identification of anomalous behavior in the equipment analyzed, whether derived from its own operations, maintenance activities, improper use of equipment or even as a result of design errors in the equipment itself. As a basis for analysis, the GAMM method uses a nonparametric estimator of the reliability function using all historical data or, alternatively, part of the history, allowing it to perform an analysis even with limited available data. In the case study developed, GAMM has been used to analyze two slurry pumps in a mining plant located in Chile. Both pumps are part of the same industrial process, which is described in Section 3, and both pumps had a higher failure rate but one more than the other. GAMM identified deficiencies in each of the pumps being studied, thus improving decision-making and problem solving process related to the maintenance of the pumps. Particularly, this work initially provides a description of the GAMM method (Section 1), and, afterwards, it is depicted with special attention the approach to the problem (Section 2). In Section 3, a background of the industrial context is presented. Then, Section 4 shows step by step the application of GAMM method. Finally, results and conclusions are presented in Section 5 where the main improvements obtained are summarized

  11. Instrumentation for mine safety: fire and smoke problems and solutions

    Stevens, R.B.

    1982-01-01

    Underground fires continue to be one of the most serious hazards to life and property in the mining industry. Although underground mines are analogous to high-rise buildings where persons are isolated from immediate escape or rescue, application of technology to locate and control fire hazards while still in their controllable state is slow to be implemented in underground mines. This paper describes several USBM (Bureau of Mines) safety programs which included in-mine testing with mine fire and smoke sensors, telemetry and instrumentation to develop recommendations for improving mine fire safety. It is hoped that the technology developed during these programs can be added to other programs to provide the mining industry with the necessary fire safety facts. By recognizing fire potentials and being provided with cost-effective, proven components that will perform reliably under the poor environmental conditions of mining, mine operators can provide protection for their working life and property equal to that which they provide for themselves and their families at home. The basis of this report is two USBM programs for fire protection in metal and nonmetal mines and one coal program. The data was collected beginning in May 1974 and continuing through the present with underground tests of a South African fire system installed at Magma Mine in Superior, Arizona, and a computer-assisted, experimental system at Peabody Coal Mine in Pawnee, Illinois

    All legal limits or recommendations concerning NORM include only primordial radionuclides and secular equilibrium state among all decay products is assumed. This is not valid for a majority of residues from NORM industry where activity concentration of progenies can substantially differ each other. Upper Silesia Coal Basin is a unique region where mining activity is continuously done over longer period of time and this include discharging of radium-bearing water to environment and creating huge amount of solid wastes where at the beginning radium is the most dominant radionuclide. With time other daughter products start to build up and actual exposure to radiation is changing. One of them is polonium that with regard to its chemical properties can be easily accumulated in non-human biota resulting in the increase of radiation exposure. In our work we focused attention on sediments where content of {sup 210}Po was determined by chemical separation followed by alpha spectrometry. Chemical preparation involves organic matter destruction and dissolution of the sample itself (if possible). In our research we employed wet digestion by means of mixture of concentrated acids: HNO{sub 3}, HClO{sub 4}, HCl. Later on polonium was spontaneously deposited onto silver disc and measured with use of alpha spectrometry. In this article we want to show results of our study and as well to present some conclusions concerning changes in radiation risk assessment when actual concentration of polonium is taken into consideration.

    The abrasive nature of the mechanical processes involved in mining and mineral industry often causes significant wear to the associated equipment and derives non-negligible economic costs. One of the possible strategies to improve the wear resistance of the various components is the deposition of hardfacing layers on the bulk parts. The use of high power lasers for hardfacing (laser cladding) has attracted a great attention in the last decade as an alternative to other more standard methods (arc welding, oxy-fuel gas welding, thermal spraying). In laser cladding the hardfacing material is used in powder form. For high hardness applications Ni-, Co- or Fe-based alloys containing hard phase carbides at different ratios are commonly used. Tungsten carbides (WC) can provide coating hardness well above 1000 HV (Vickers). In this respect, commercially available WC powders normally contain spherical micro-particles consisting of crushed WC agglomerates. Some years ago, Spherotene powders consisting of spherical-fused monocrystaline WC particles, being extremely hard, between 1800 and 3000 HV, were patented. Very recently, mixtures of Ni-based alloy with Spherotene powders optimized for laser processing were presented (Technolase). These mixtures have been used in our study. Laser cladding tests with these powders were performed on low carbon steel (C25) substrates, and results in terms of microstructure and hardness will be discussed

    One of the most promising areas in the mining industry is the development of devices for measuring solid mass flowrate in pipelines, mainly in transportation of ore. These units are composed of interconnected pipes where transport of the material is accomplished by pumps capable of driving the ore pellets using water. One of the problems inherent in these systems is the stratification if a critical velocity is reached, the ore pellets begin to sediment at the bottom of the pipe and it may block the system. The solid phase displacement behavior depends on a number of factors (water flowrate, density, pipe diameter, average size of the pellet) which makes the flow regime knowledge essential to the appropriate operation of the system. An apparatus to evaluate the stratification level through of particle (ore pellets) spatial distributions inside the pipe is important because it increases the safety condition of pumping and transportation of solid phase. Therefore, this work presents a study to optimize the geometrical parameters for the identification of a possible stratification of the solid phase inside a pipeline. The detection system uses different NaI(Tl) detectors and gamma ray sources (fan beam geometry), adequately positioned in order to calculate transmitted and scattered beams. Additionally, theoretical models for different flow regimes (homogeneous and stratified) have been developed using MCNP-X mathematical code. (author)

  15. Finding occupational accident patterns in the extractive industry using a systematic data mining approach

    This paper deals with occupational accident patterns of in the Portuguese Extractive Industry. It constitutes a significant advance with relation to a previous study made in 2008, both in terms of methodology and extended knowledge on the patterns’ details. This work uses more recent data (2005–2007) and this time the identification of the “typical accident” shifts from a bivariate, to a multivariate pattern, for characterising more accurately the accident mechanisms. Instead of crossing only two variables (Deviation x Contact), the new methodology developed here uses data mining techniques to associate nine variables, through their categories, and to quantify the statistical cohesion of each pattern. The results confirmed the “typical accident” of the 2008 study, but went much further: it reveals three statistically significant patterns (the top-3 categories in frequency); moreover, each pattern includes now more variables (4–5 categories) and indicates their statistical cohesion. This approach allowed a more accurate vision of the reality, which is fundamental for risk management. The methodology is best suited for large groups, such as national Authorities, Insurers or Corporate Groups, to assist them planning target-oriented safety strategies. Not least importantly, researchers can apply the same algorithm to other study areas, as it is not restricted to accidents, neither to safety.

In this vision, I propose the establishment of management of the production process that uses as its objective "the cost". Target calculation system is expected to be made up of a set of methods, techniques and means with which to accurately predict and programme production costs, to calculate the cost of an hour of activity, to register and to consider pre-emptive, operative and post operative expenses compared to the deviations of their standard or normed and, on this basisto determine the actual cost of production at the end of each cycle of activity

    Full Text Available South Africa needs to increase its inward foreign direct investment in order to achieve economic growth. The purpose of this article is to explore which intervention could be launched in the short term to enhance the country's attractiveness for foreign investors. The findings of the literature review demonstrated that incentives, as a determinant of investment, are the short-term intervention with the most significant potential to attract additional foreign direct investment. A comparative study, which provided insight into the incentives that are currently offered to the manufacturing sectors of three countries (South Africa, Malaysia and Singapore, assisted in identifying two additional incentives that the South African government could introduce and three existing incentives that could be amended. The introduction or modification of these incentives could ensure that South Africa has a competitive advantage to attract investment from foreign investors and thereby increase South Africa's inward foreign direct investment in the manufacturing industry.

  3. 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

    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.

    Full Text Available The purpose of this study is to examine to what extent South African companies listed on the local stock exchange in the mining and food producer and retail sectors are including biodiversity-related issues in their integrated and sustainability reports. The study employs established biodiversity reporting frameworks for gauging changes in the frequency of disclosures from 2011 to 2013 and determining if biodiversity information is being included in either the integrated or sustainability reports of the companies under review. Consistent with the findings of a special edition of Accounting, Auditing and Accountability Journal (AAAJ, the research finds few examples of detailed reporting on biodiversity issues. This is despite the fact that South Africa has a well-established code of corporate governance, a long history of including non-financial information in corporate reports and is an advocate of the integrated reporting movement. The study calls into question the sincerity of companies in the two sectors under review when it comes to providing balanced accounts of their management of non-financial capital as recommended by the country’s codes on governance and the International Integrated Reporting Council.

    2013-04-01

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

    The province of Quang Ninh in the north of Vietnam is the most important coal mining region in the country. The NBCC (Nui Beo Coal Company) operates several open-cast mines. Large quantities of overburden have to be removed and dumped in the immediate environment. The creation of these heaps up to 300 m high is accompanied by many environmental problems. In particular ground and surface waters are contaminated by ''acid mine drainage''. Furthermore, large emissions chiefly in the form of dust occur as a result of the working and dumping depending on the season. In addition the stability of the heaps is sometimes greatly endangered. In the German-Vietnamese Research Association Mining and Environment in Vietnam (RAME) the aspects of coal mining with an effect on the environment are dealt with in various sub-associations and protective measures worked out jointly.

    2006-01-01

    Full Text Available Abstract Background Spain shows the highest bladder cancer incidence rates in men among European countries. The most important risk factors are tobacco smoking and occupational exposure to a range of different chemical substances, such as aromatic amines. Methods This paper describes the municipal distribution of bladder cancer mortality and attempts to "adjust" this spatial pattern for the prevalence of smokers, using the autoregressive spatial model proposed by Besag, York and Molliè, with relative risk of lung cancer mortality as a surrogate. Results It has been possible to compile and ascertain the posterior distribution of relative risk for bladder cancer adjusted for lung cancer mortality, on the basis of a single Bayesian spatial model covering all of Spain's 8077 towns. Maps were plotted depicting smoothed relative risk (RR estimates, and the distribution of the posterior probability of RR>1 by sex. Towns that registered the highest relative risks for both sexes were mostly located in the Provinces of Cadiz, Seville, Huelva, Barcelona and Almería. The highest-risk area in Barcelona Province corresponded to very specific municipal areas in the Bages district, e.g., Suría, Sallent, Balsareny, Manresa and Cardona. Conclusion Mining/industrial pollution and the risk entailed in certain occupational exposures could in part be dictating the pattern of municipal bladder cancer mortality in Spain. Population exposure to arsenic is a matter that calls for attention. It would be of great interest if the relationship between the chemical quality of drinking water and the frequency of bladder cancer could be studied.

  19. 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.

    2012-04-01

    Two underground sites in a deep level gold mine in South Africa were instrumented by the Council for Scientific and Industrial Research (CSIR) with tilt meters and seismic monitors. One of the sites was also instrumented by JApanese-German Underground Acoustic emission Research in South Africa (JAGUARS) with a small network, approximately 40m span, of eight Acoustic Emission (AE) sensors. The rate of tilt, defined as quasi-static deformations, and the seismic ground motion, defined as dynamic deformations, were analysed in order to understand the rock mass behavior around deep level mining. In addition the high frequency AE events recorded at hypocentral distances of about 50m located at 3300m below the surface were analysed. A good correspondence between the dynamic and quasi-static deformations was found. The rate of coseismic and aseismic tilt, as well as seismicity recorded by the mine seismic network, are approximately constant until the daily blasting time, which takes place from about 19:30 until shortly before 21:00. During the blasting time and the subsequent seismic events the coseismic and aseismic tilt shows a rapid increase.Much of the quasi-static deformation, however, occurs independently of the seismic events and was described as 'slow' or aseismic events. During the monitoring period a seismic event with MW 2.2 occurred in the vicinity of the instrumented site. This event was recorded by both the CSIR integrated monitoring system and JAGUARS acoustic emotion network. The tilt changes associated with this event showed a well pronounced after-tilt. The aftershock activities were also well recorded by the acoustic emission and the mine seismic networks. More than 21,000 AE aftershocks were located in the first 150 hours after the main event. Using the distribution of the AE events the position of the fault in the source area was successfully delineated. The distribution of the AE events following the main shock was related to after tilt in order to

    ENGLISH ABSTRACT: Industrial engineering (IE is a multi-disciplinary field, with its research borders broadening into a wide range of sub-disciplines. The South African Journal of Industrial Engineering (SAJIE has been the official voice of IE research in South Africa for the past 22 years. In the interests of evaluating research scope, it is worth determining how IE fields have been covered by this journal. What are the current topics in IE, and how do they align with IE publication trends in other countries? This article attempts to investigate these issues in an objective way by using a text analytical technique to analyse the SAJIE publication collection. Due to the growth in the quantity of accessible textual information, and the growing importance of this type of information to business people and industrial engineers alike, the relevant text analytical method is also outlined.

    Tanzania has recently developed a comprehensive environmental policy which has put high priority on several specific environmental issues. One of the issues is the quality of waste water. A special priority is given to the pollution from the sisal industry. The East-African agro-industries generate very large quantities of organic residues from production and processing of different crops. These residues form a major contribution to the pollution of air, soil and waterways, but, at the same time they constitute a large potential for production of bioenergy through anaerobic digestion as well as potential substrate for other biological fermentation processes. Generally, these residues are regarded as having no or very little value and the different disposal methods are mainly a matter of getting rid of the waste. The generation of residues are very often concentrated on few large units, which makes the exploitation of these resources feasible in large scale biogas systems. Typically the units will have a potential of a daily methane generation of 1,000-20,000 m{sup 3} CH{sub 4}, equivalent to a potential electricity production of 0.2-3.2 MW. The future utilization of these resources for production of valuable products is described in this report. This report consists of 3 volumes. This summary report including the main objectives and findings from the different project report: Mapping and Quantification of Organic Agro-Industrial Residues in East Africa; Biogas - Bioenergy Potential in East Africa, Seminar Proceedings, Siler Sands, Dar es Salaam 22-23 September 1997; Bioenergy from Sisal residues - Experimental results and Capacity Building Activities.

    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.

    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

    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.

    Full Text Available Reporting on contributions to community development is one way gold mining companies communicate the expanse and depth of their commitment to social responsibility. These projects are intended to provide the mine-proximate communities with some of the wealth and other benefits generated by mine development in their locales. We raise questions about reporting and evaluation of community development projects undertaken by AngloGold Ashanti in the two communities of Nyakabale and Nyamalembo, near its Geita mining projects in the Lake Victoria goldfields of Tanzania. We use archival data and data obtained from field research conducted during different periods throughout 2005, 2007 and 2010 to compare what the company reports to have done with what is found on the ground. Our findings revealed that the corporate reporting is misleading, ambiguous, and omissive. Much of the effort labeled “community development” benefited the companies directly via infrastructure development, food supplies to the mine cafeteria, and worker health. We argue that, if Corporate Social Responsibility (CSR projects are to be the primary way local people directly benefit from mine development, the relationship between the value of those projects and the wealth taken from the location should be considered, community projects should be well defined and differentiated from company-oriented projects, and community representatives should participate in monitoring the success and impact of community development projects.

    To estimate quantitative levels of exposure to diesel exhaust expressed by elemental carbon (EC) in the contemporary mining industry and to describe the excess risk of lung cancer that may result from those levels. EC exposure has been monitored in Western Australian miners since 2003. Mixed-effects models were used to estimate EC levels for five surface and five underground occupation groups (as a fixed effect) and specific jobs within each group (as a random effect). Further fixed effects included sampling year and duration, and mineral mined. On the basis of published risk functions, we estimated excess lifetime risk of lung cancer mortality for several employment scenarios. Personal EC measurements (n=8614) were available for 146 different jobs at 124 mine sites. The mean estimated EC exposure level for surface occupations in 2011 was 14 µg/m 3 for 12 hour shifts. Levels for underground occupation groups ranged from 18 to 44 µg/m 3 . Underground diesel loader operators had the highest exposed specific job: 59 µg/m 3 . A lifetime career (45 years) as a surface worker or underground miner, experiencing exposure levels as estimated for 2011 (14 and 44 µg/m 3 EC), was associated with 5.5 and 38 extra lung cancer deaths per 1000 males, respectively. EC exposure levels in the contemporary Australian mining industry are still substantial, particularly for underground workers. The estimated excess numbers of lung cancer deaths associated with these exposures support the need for implementation of stringent occupational exposure limits for diesel exhaust.

    Full Text Available Orientation: Owing to the nature of the tourism industry, which is highly service orientated, employees should possess certain skills such as self-reliance, people and certain specialist skills, and general employability when working in this industry. However, it seems that employees are not well enough prepared and equipped with these skills to satisfy the requirements of employers. Thus human resource practitioners need to provide more in-service training. Furthermore, there is a high turnover of employees, which adds pressure to the management of human resources. Research purpose: This study focused on comparing employers’ expectations of employee skills in the tourism industry and the skills acquired by learners in the Culture, Art, Tourism, Hospitality and Sport Skills Education Training Authorities’ (CATHSSETA programmes with regard to self-reliance, people and certain specialist skills, and general employability. Motivation for the study: Education, training and the creation of employment are amongst the key priorities of the South African government for improving the current labour situation in the tourism industry. However, the industry has complained that learners are not prepared for the workplace. Thus, it is important to determine the skills that are supposedly lacking. Research design, approach and method: Descriptive research, following a quantitative approach, was chosen, whereby questionnaires were distributed amongst tourism and hospitality employers listed with CATHSSETA (N = 217. A total of 141 (n = 141 completed questionnaires were received (a response rate of 65%. Between 2008 and 2012, 5633 learners participated in the CATHSSETA programmes. Descriptive statistics and t-tests were used to analyse the data. Main findings: Employers expect higher levels of competence than those which learners in the CATHSSETA programme can deliver. More specifically, employers indicate that learners lack skills in handling customers

    To date, there have been few detailed studies regarding the impact of mining and metallogenic activities on solid fractions in the Azzaba mercurial district (northeast Algeria) despite its importance and global similarity with large Hg mines. To assess the degree, distribution, and sources of pollution, a physical inventory of apparent pollution was developed, and several samples of mining waste, process waste, sediment, and soil were collected on regional and local scales to determine the concentration of Hg and other metals according to their existing mineralogical association. Several physico-chemical parameters that are known to influence the pollution distribution are realized. The extremely high concentrations of all metals exceed all norms and predominantly characterize the metallurgic and mining areas; the metal concentrations significantly decrease at significant low distances from these sources. The geo-accumulation index, which is the most realistic assessment method, demonstrates that soils and sediments near waste dumps and abandoned Hg mines are extremely polluted by all analyzed metals. The pollution by these metals decreases significantly with distance, which indicates a limited dispersion. The results of a clustering analysis and an integrated pollution index suggest that waste dumps, which are composed of calcine and condensation wastes, are the main source of pollution. Correlations and principal component analysis reveal the important role of hosting carbonate rocks in limiting pollution and differentiating calcine wastes from condensation waste, which has an extremely high Hg concentration (˃1 %).

    2014-10-01

    Full Text Available Purpose: Mining industry has always been known for its unsafe working environment. This industry is one of the most hazard prone industries. To maintain safety in workplace timely assessment of risk associated with different operations performed to extract ore from the ore body has become necessity. To serve the said purpose, present work demonstrates a robust hybrid risk assessment approach for mining industry.Design/Methodology: Accident data from 1995 to 2012 is reviewed to identify hazards contributed to negative outcomes. The FRA approach is implemented to evaluate the risk levels associated with identified hazard factors. Thereafter AHP pairwise comparison matrix is developed to obtain priority weights for the hazard factors. Final priority of hazards based on severity of level of risk associated with them is obtained considering the outcome of FRA approach in terms of risk score for the hazards, combined with the priority weights obtained from AHP technique.Findings: Defuzzified FAHP weight of hazard factors, this weight gives priority sequence of hazards to be considered for development of plan of mitigation.Originality/Value: Risk assessment is a requirement of the Occupational Health and Safety Act 2000 (Section 7& 8. The data required to assess the risk is uncertain, and in such case fuzzy approach is well suited to process the data and get the crisp output. The output of fuzzy approach is made robust with its integration to AHP. In this way FAHP can be used as robust technique for risk assessment in this industry and this technique develops an efficient safety management system for the achievement of goal to develop the workplace with zero accident, which many other countries have already achieved.

    The acid mine drainage is one of the most important environmental problems associated with mining of ores containing sulfides. The treatment of these acid effluents, which contains high concentrations of dissolved metals and anions, is generally by liming. The wastes generated in the liming process may present significant toxicity and their storage in inappropriate places waiting for treatment is a common issue that requires solution. Osamu Utsumi Mine located in the city of Caldas, Minas Gerais, has been facing this problem. The residue of this mine consists of an alkaline sludge generated from the neutralization of the pH of acid mine drainage and is rich in various metals, including uranium. The main concern is the long term stability of this residue, which is in permanent contact with the acid water in the open pit. The recovery of uranium by hydrometallurgical techniques, such as acid leaching, can be a viable alternative on the reuse of this material. This study aimed at establishing a specific leaching process for the recovery of uranium present in the sludge from Caldas uranium mine. Some parameters such as solid/liquid ratio (0.09 to 0.17), time of leaching (1 to 24 hours) and concentration of sulfuric acid (pH from 0 to 3.0) were assessed. The results showed that it is possible to extract 100% of uranium present in the sludge. The concentration of U{sub 3}O{sub 8} in the residue was 0.25%, similar to the content of the vein ores which is around 0.20% to 1.0%. The best experimental leaching condition is solid/liquid ratio of 0.17, pH 1.0 and 2 hours of reaction at room temperature (25 deg C). The content of uranium in the liquor is around 440 mgL{sup -1}. The recovery of the uranium from the liquor is under investigation by ionic exchange. (author)

    Full Text Available Purpose of this paper: Procurement systems are vital in ensuring the successful implementation of construction projects precisely in all the phases of any particular project. Therefore, this paper aims to investigate in a systematic manner the factors that influence the selection of a procurement system in the South African construction industry. Research methodology: An extensive theory and literature review of procurement systems was conducted. The literature reviewed included a sample of case studies of procurement systems successfully implemented in completed building and civil engineering projects in South Africa. A questionnaire using a four-round Delphi survey method was used to conduct the empirical study in order to obtain participants' opinions about factors influencing the selection of procurement systems as well as the utility value of various procurement systems on each factor as identified. Finally, data analysis of both qualitative and quantitative techniques was performed using the Statistical Package for Social Sciences (SPSS. Findings: After qualitative analysis, findings of the literature reviewed suggest that factors that influence the selection of procurement systems cut across all the phases of the project as identified in this paper. Therefore, these factors are categorically classified into internal and external factors. Factors from the internal environment were further classified into client characteristics and project characteristics, with client characteristics comprising of variables such as clients' level of knowledge and control, political and social consideration, familiarity of procurement systems, competition, funding arrangement, government public/private sector projects and risk allocation whereas project characteristics comprise of factors (variables such as size and technical complexity of the project, influence of the project life cycle, expedited project delivery, time, quality and price certainty.

  5. What Gives You a Social Licence? An Exploration of the Social Licence to Operate in the Australian Mining Industry

    Directory of Open Access Journals (Sweden)

    Sara Bice

    2014-01-01

    Full Text Available This article analyses the ways in which major, multinational mining companies operating within Australia understand sustainable development and articulate their “social licence to operate”. The article contributes a novel perspective to ongoing discussions about the social licence by exploring the ways in which leading Australian mining companies define and assert their social licences through sustainable development discourse. A content and discourse analysis of 18 sustainability reports across a four year period, supplemented by qualitative interview data, draws out these issues. While most companies use these reports to confirm beliefs in the necessity of a social licence, the ways in which the licence is specifically defined and maintained are not generally made explicit. Additionally, key theoretical criteria required for a social licence, such as free, prior and informed consent, appear to be overlooked. In conclusion, the article suggests ways in which criteria for a social licence within the mining industry could be defined more clearly and raises consequent questions to shape future research.

  6. Investigation of mine and industry dumps in Lower Saxony (FRG) in relation to a possible release of natural radioactive elements

    Schmitz, J.; Klein, H.

    1985-09-01

    More than 230 dumps of mines and industries in the country of Lower Saxony (FRG) were recorded, radiometrically measured, evaluated and some of them sampled. Most of the mine dumps belonged to old and smaller residues of the lead/zinc and iron ore mining while the largest depositions contain tailings of modern ore benificiation or fly ash disposal. The highest doses, up to 2 mSv/a, were found on the dumps of the redmud and phosphate-gypsum deposits. These are followed by fly ash and slag dumps which show doses between 1 and 2 mSv/a. The lowest doses were found on the dumps of the hydrothermal Pb/Zn and iron ore deposits, while the slag piles of the iron ore processing showed higher thorium values. The uranium-, Ra-226- and Pb-210 analyses of the deposited materials confirmed the radiometric results. The analysis of seepage and gallery waters showed only a small number of values exceeding the derived drinking water concentrations. The examination of nearly all mineral deposition in Lower Saxony have clearly shown that primary radioecological impacts can be excluded, which might be not the case when the deposited material undergoes a recycling process.

    At the Waste Isolation Pilot Plant (WIPP) traditional procedures for underground mining activities have been significantly altered in order to assure underground safety and project adherence to numerous regulatory requirements. Innovative techniques have been developed for WIPP underground procedures, mining equipment, and operating environments. The mining emphasis at WIPP is upon the quality of the excavation, not (as in conventional mines) on the production of ore. The WIPP is a United States Department of Energy (DOE) project that is located 30 miles southeast of Carlsbad, New Mexico, where the nation's first underground engineered nuclear repository is being constructed. The WIPP site was selected because of its location amidst a 607 meter thick salt bed, which provides a remarkably stable rock formation for the permanent storage of nuclear waste. The underground facility is located 655 meters below the earth's surface, in the Salado formation, which comprises two-hundred million year old halites with minor amounts of clay and anhydrites. When completed, the WIPP underground facility will consist of two components: approximately 81 square kilometers of experimental areas, and approximately 405 square kilometers of repository. 3 figs

    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.

    INGEOMINAS carried out this project in the cities of Cartagena, Bucaramanga, Cali and Bogota, in two phases: Phase 1 (Diagnostic) and Phase II (Formulation of Handling Plan). The phase 1 that here is described, it upgrades the knowledge of the extractive industry of the construction materials for the city of Cartagena, through bibliographical revision and field work, carried out in 50 quarries that supply from these materials to the city. This study, besides the economic and legal handling, identifies technical aspects related with the geology, the mining and the environmental situation. In accordance with their likeness, geologic, morphological and of exploitation (extraction methods and mining development), the quarries met in five groups: Exploitations on calcareous deposits of the La Popa Formation, exploitations on clay deposits of the La Popa Formation, exploitations on detritus deposits of half grain to thick (La Popa-Arenosa Formation; Pendales Conglomerate and Rotinet Formation) and exploitation of calcareous of the Arroyo de Piedra Formation. The extraction of these materials is characterized by its low degree of development technician, lack of planning mining, lack of appropriate infrastructure that allows a better development of the sector, is also evident the control lack on the part of the entities in charge of the handling of this industry. These factors added to a demand every time in increase of these materials, they have taken to a progressive deterioration in the landscape, increase of the noise and particles in the air and in the waters. The low control in this activity has generated the proliferation of informal exploitations that they find in this activity a way of subsistence

    Full Text Available Industrial restaurants generate, when preparing and serving meals, a number of wastes that are administered in different ways. However, increasing waste generation leads to the need of establishing measures capable of permanently control the environmental effects of the entire production process. In this sense, this work aimed at verifying the generation of organic residues from the industrial restaurant of Cauê Mine, located in the Itabira/MG Mining Complex, as well as to evaluate if the technologies currently used for the management of these wastes are environmentally sustainable and economically viable. Thus, it was sought to identify the foods responsible for their higher generation, resulting in the alteration of the menu and, consequently, a reduction of 81.85% of organic residues. Another important factor was the reuse of fruit peels in desserts, providing healthier foods and reducing the amount of waste sent to the final treatment. Regarding the final disposal of organic waste in the landfill, it was observed that during the analyzed period there was a reduction of 64.67% of the values initially paid. In the aspect related to waste, it was found that the campaigns developed aiming at the "zero waste" of both restaurant staff and customers, also had a positive influence on the reduction of residual "ingestion" waste.

    The present work focuses on the characterization of air quality and the identification of pollutant origin at a former mining site in the city of Lavrion, Greece. A historical metallurgy complex is reused for establishing the Lavrion Technology and Cultural Park (LTCP). A serious problem with this is the severe soil contamination that resulted from intensive mining and metallurgical activities that has taken place in the greater area for the past 3,000 years. Among other consequences, surface-polluted depositions, rich in heavy and toxic metals, are loose and easily wind-eroded, resulting in transportation of particulate matter (PM) in the surrounding atmosphere. On the other hand, there are a number of industries relatively close to the site that are potential sources of PM air pollution. The current study deals with the collection and analysis of PM10 samples with respect to their concentration in heavy metals, such as Pb, Cd, Cu, Fe, Zn, Mn, Cr, and Ni. Though not a heavy metal, As also is included. Furthermore, the source of these elements is verified using statistical correlation and by calculating enrichment factors (EFs), considering that some substances are certainly of contaminated soil origin. Results show that PM10 and element concentrations are relatively low during winter but significantly increase during summer. Fe, Pb, Zn, Mn, and Cu may be considered of contaminated soil origin, while As, Ni, Cd, and Cr are very much enriched with respect to contaminated soil, indicating another possible source attributed to the adjacent industrial plants.

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

News articles and interviews with executives, however, indicate that firms from time to time engage in cost-cutting exercises. One popular belief is that firms cut costs when they are in economic distress, and grow fat when they are relatively wealthy....
