    The French mining adventure still arouses enthusiasm. The search for uranium began in 1945 with the creation of the Cea (Atomic Energy Board) whose one mission was to supply the nascent French nuclear programme with the necessary materials. Prospecting works were then led throughout France, Madagascar, the Ivory Coast and the French equatorial Africa. More than 60 years later the only surviving actor of this quest for uranium has become the mining department of Areva Nuclear Cycle which is itself a sub-company of Areva. The author, who was an ancient high executive of Cogema draws a detailed history of the French uranium mining industry with with its ups and downs, by analysing the impact of the 2 oil crisis and of the decline of nuclear energy in the decade following the Chernobyl accident.

    Full Text Available Recently, stakeholders demand that CSR reporting of a company provides social and environmental information as well as the financial information reported in financial statement. This research questioned whether CSR reporting of Indonesian mining companies may be regarded as a mechanism which social and environmental accountability are discharged. The purpose of this research is to provide a content analysis framework and information on the comprehensiveness of Corporate Social Responsibility (CSR reporting of Indonesian mining companies. The methodology used is content analysis method by a framework derived from GRI G3.1 Guidelines. Comprehensive reporting contains three types of information for each disclosed CSR item: (i vision and goals, (ii management approach, and (iii performance indicator. The framework was used to assess the comprehensiveness of CSR report by analyzing the 2012 financial reports and annual reports of Indonesian listed mining companies. The content analysis of CSR reporting of the listed mining companies in Indonesia shows a low level of comprehensive reporting. This finding agrees those of prior studies on the completeness of CSR reporting and adds to the debate regarding whether CSR reporting of Indonesian mining companies can be considered a mechanism for discharging social and environmental accountability.

  12. Development growth of uranium reserves during mining

    Giroux, M.

    1989-01-01

    According to the 1988 issue of the Nuclear Energy Agency report 'Uranium Resources, Production and Demand' (the Red Book), total uranium resources remained constant, and compare with those given in the 1986 issue. However, the low cost category of the Reasonably Assured Resources (RAR), that is to say potentially mineable reserves under present market conditions, presents a different picture. These show a decrease of 54 000 tonnes U, or about 3.5%, from the 1 January 1985 level. It seems insignificant until compared with what was removed from the ground - only a quarter of the 71 500 tonnes U of the low cost uranium that was extracted during 1985 and 1986 was renewed by the industry. This is probably related to the low level of exploration activity since 1983. Moreover, new uranium might be not as easy to find as some past discoveries have led us to believe. While in 1988 it appears there is enough low cost uranium to supply existing reactors, the picture quickly changes. From 1991 onwards, for 30 years' supply for existing reactors, uranium will have to come from RAR in the higher cost category. (author)

    Profitability of copper deposit mining depends on three basic variables, electrolytic copper price, manufacturing and selling costs of copper and company property involved in production process. If the company property is adjusted to its tasks then the mining profiability depends on costs of copper mining and selling, because the price is the external variable defined by the market. We can shape the costs in two (complementary) ways, traditionally, reducing the labor, material and power consumption, and by adjusting the quality of mined ore (copper content) to the level required by the current copper prices. Required quality of copper ore in the whole company we determine according to the accepted profitability criteria and then we determine quality standard for individual mines. Algorithms determining the ore quality standard resulting from current market price of copper are presented in the paper. Calculation models for the mined ore quality standards, unit mining costs per one ton of copper, electrolytic copper production and ore output are given. Standards were established for one variable assuming that the other variables are determined in this calculation. Innovative solution, presented in the paper, is the method of decomposition of the company controllable variables into the tasks for individual mines providing reaching the targets to the whole technological circuit. Using the models, having relatively few data, it will be possible to calculate quickly the values which are interesting for managers such as for example the prognosis of rate of return (economic or operational), required copper content in the mined ore for the whole company and individual mines at given rate of return or boundary level of copper content in comparison with cost and production level. Examples of calculation are provided. (orig.)

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

  15. The levels of disclosure relating to mine closure obligations by platinum mining companies

    2017-06-01

    Aim: The aim of this study is to establish the extent to which platinum mines listed on the Johannesburg Stock Exchange (JSE comply with a recommended disclosure framework. Setting: South Africa is the largest producer of platinum in the world. The study covers all platinum mines listed on the JSE. Methods: Using a framework, a census of the annual financial statements, integrated annual reports and sustainability reports or websites was conducted to determine the level of compliance of disclosure relating to mine closure obligations to the recommended disclosure framework. Results: The results show disclosure relating to mine closure obligations of platinum mines listed on the JSE is inconsistent and not sufficient for stakeholders to understand the scope, key assumptions, parameters or reliability of the assessment and calculation of mine closure obligations. Conclusion: The assumptions used to determine mine closure obligations are specialised and multi-disciplinary. The accuracy and reliability of mine closure obligations will improve dramatically through greater transparency and access to information. It is recommended that the JSE listings for mining companies should require a competent person’s report to provide disclosure on assumptions, key values and processes applied to determine the mine closure obligations. Furthermore, it is recommended that the Department of Mineral Resources implements a mechanism of independent assessment of mine closure obligations by experts on an ongoing basis.

    2009-01-01

    As a result of Structural Adjustment Programme from the 1980s, many developing countries have experienced an increase in resource extraction activities by international and transnational corporations. The work reported here examines the perceived impacts of gold mining at the community level in the Wassa West District of Ghana, Africa and discusses those perceived impacts in the context of globalization processes and growing multinational corporate interest in Corporate Social Responsibility (CSR). Interview data compared community members' perceptions with those of company representatives in three communities. The results indicate that communities held companies responsible for a series of economic, social, and environmental changes. While recognizing some of the benefits brought by the mines, communities felt that the companies did not live up to their responsibility to support local development. Companies responded by denying, dismissing concerns, or shifting blame. Findings from this work show that lack of engagement and action by government agencies at all levels resulted in companies acting in a surrogate governmental capacity. In such situations, managing expectations is key to community-company relations.

  17. Horizontal integration in the development strategy of mining companies

    Full Text Available Integration strategy is one option in the development of mining companies and is implemented through a connection of either processes or economic entities which operate or may operate separately. Usually this strategy is carried out by companies that occupy a very strong competitive position. Considering its direction, it may be horizontal or vertical. Horizontal integration strategy stems from a desire to increase market share by an entrepreneur or create a new company based on common know-how and combined operational processes. It can be realized in an external dimension through a merger or takeover, as well as in the internal dimension based on its own resources. The external dimension is based on capital or contractual integration of a company with external economic entities performing related or conglomerate activity. The targets of such integration have a resource, a market effectiveness, or a competence nature. In the case of mining companies, it covers all important activity areas, including geology, mining, processing, environmental protection, and waste management, and is carried out with due diligence. In the internal dimension, the strategy of horizontal integration consists in consolidating the strategic targets of all business units around the company’s (corporation’s targets. The authors focused on two trends most relevant to pursuing a horizontal integration strategy, including increasing the company’s flexibility and undertaking joint activities. Flexibility consists in the potential ability of the company to adapt quickly to changed environment conditions. Joint activity includes co-operation of its respective units in terms of products, markets, and functions.

    1994-01-01

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

    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.

    Creating a soft-landing path for mine closure is key to the sustainability of the mining region. In this research, we presents a case of mine closure in Soroako, a small mining town in the north-east of South Sulawesi province, in the center of Sulawesi Island in Indonesia. Especially we investigates corporate social responsibility (CSR) programs of a mining company, PT Vale Indonesia Tbk (PTVI), towards a soft-landing of mine closure in this region. The data of the CSR programs are gathered from in-depth interviews, the annual reports and managerial reports. Furthermore we presents an integrated view of CSR to close mining in a sustainable manner. We then evaluate CSR strategies of the company and its performance from this viewpoint. Based on these steps, the way to improve the CSR mine closure scenario for enhancing the regional sustainability is discussed and recommended.

    The paper empirically compares employee motivation and its impact on performance in Ghanaian Mining Companies, where in measuring performance, the job satisfaction model is used. The study employed exploratory research design in gathering data from four large-scale Gold mining companies in Ghana with regards to their policies and structures in the effectiveness of motivational tools and strategies used by these companies. The study observed that, due to the risk factors associated with the mining industry, management has to ensure that employees are well motivated to curb the rate at which employees embark on industrial unrest which affect performance, and employees are to comply with health and safety rules because the industry contribute hugely to the Gross Domestic Product (GDP) of the country. Limitation to the present study include the researcher’s inability to contact other mining companies. However, the study suggests possibilities for future research including contacting other mining companies, expanding the sample size, managers ensuring that the safety and health needs of staff are addressed particularly those exposed to toxic and harmful chemicals. A lot of studies have been done on mining companies in the past.

    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.

    Full Text Available Commercial insurance companies are liable to create, on the basis of risks arising from the fulfillment of the object of their activity, technical reserves, which are used to cover liabilities arising to insurance companies from insurance and reinsurance activity. The paper focuses on the technical reserve which is, in accordance with the accounting-legal regulation, created obligatorily in commercial insurance companies – it is the unearned premium reserve.The paper explores the role and place of this technical reserve in the accounting of the commercial insurance companies based on the analysis of its substance, i.e. the objective definition. The paper is based on the methodology of the accounting, evaluation and methods of determining the amount of the technical reserve which will affect the income from operations as well as income tax base of commercial insurance companies. The paper also studied the method of reporting of unearned premium reserve in accounting according to Czech accounting legislation in comparison with International Accounting Standards (IAS/IFRS. The aim of this paper is to determine the impacts of the creation and application of the unearned premium reserve on some important items of the financial statements, which are mainly the income of operations, equity capital and balance sheet as well as to identify the impacts of different reporting of this reserve according to Czech accounting legislation and in accordance with IAS/IFRS. Performing the analysis of the accounting-legal regulation of the unearned premium reserve in the insurance companies, the analysis of the method of accounting of this reserve and also the comparison of reporting of this reserve according to both mentioned regulations is a prerequisite for the fulfillment of the aim.

  12. Preliminary analysis of surface mining options for Naval Oil Shale Reserve 1

    Energy Technology Data Exchange (ETDEWEB)

    1981-07-20

    The study was undertaken to determine the economic viability of surface mining to exploit the reserves. It is based on resource information already developed for NOSR 1 and conceptual designs of mining systems compatible with this resource. Environmental considerations as they relate to surface mining have been addressed qualitatively. The conclusions on economic viability were based primarily on mining costs projected from other industries using surface mining. An analysis of surface mining for the NOSR 1 resource was performed based on its particular overburden thickness, oil shale thickness, oil shale grade, and topography. This evaluation considered reclamation of the surface as part of its design and cost estimate. The capital costs for mining 25 GPT and 30 GPT shale and the operating costs for mining 25 GPT, 30 GPT, and 35 GPT shale are presented. The relationship between operating cost and stripping ratio, and the break-even stripping ratio (BESR) for surface mining to be competitive with room-and-pillar mining, are shown. Identification of potential environmental impacts shows that environmental control procedures for surface mining are more difficult to implement than those for underground mining. The following three areas are of prime concern: maintenance of air quality standards by disruption, movement, and placement of large quantities of overburden; disruption or cutting of aquifers during the mining process which affect area water supplies; and potential mineral leaching from spent shales into the aquifers. Although it is an operational benefit to place spent shale in the open pit, leaching of the spent shales and contamination of the water is detrimental. It is therefore concluded that surface mining on NOSR 1 currently is neither economically desirable nor environmentally safe. Stringent mitigation measures would have to be implemented to overcome some of the potential environmental hazards.

  13. The use of data mining by private health insurance companies and customers' privacy.

    2015-07-01

    This article examines privacy threats arising from the use of data mining by private Australian health insurance companies. Qualitative interviews were conducted with key experts, and Australian governmental and nongovernmental websites relevant to private health insurance were searched. Using Rationale, a critical thinking tool, the themes and considerations elicited through this empirical approach were developed into an argument about the use of data mining by private health insurance companies. The argument is followed by an ethical analysis guided by classical philosophical theories-utilitarianism, Mill's harm principle, Kant's deontological theory, and Helen Nissenbaum's contextual integrity framework. Both the argument and the ethical analysis find the use of data mining by private health insurance companies in Australia to be unethical. Although private health insurance companies in Australia cannot use data mining for risk rating to cherry-pick customers and cannot use customers' personal information for unintended purposes, this article nonetheless concludes that the secondary use of customers' personal information and the absence of customers' consent still suggest that the use of data mining by private health insurance companies is wrong.

    This study consolidates and evaluates information and data obtained from a coal mining company's return to work program called the Work Therapy Program. Organizational information and economic and statistical data were available for the study based on the company's records. Analysis of the data included descriptive statistics such as total injuries, the frequency rate of injuries, total days away from work due to injury, average days away per employee, and severity rates. A cost-benefit analysis was conducted to determine if the Program was economically beneficial to the company. Data from an opinion survey of the management at the mine where the Program was first instituted was used to determine the perceptions of mine management with respect to the Work Therapy Program. Conclusions were that the Work Therapy Program was economically beneficial to the Company and that the Program resulted in a significant reduction in compensable injuries. The Program did not significantly reduce days away from work due to mine injury. Perceptions of mine management were mostly positive

    Full Text Available Mining in tropical countries contributes significantly to the global minerals supplies but unregulated mining activities in reserved forests is associated with destruction, loss of habitats and loss of biodiversity. This study determined the area of the Offin shelterbelt forest reserve, Ghana, degraded through illegal mining (galamsey and the impacts on the livelihoods of fringe communities. Thirty-two (32 coordinates were recorded around the peripheries of disturbed site in the reserve using hand-held Global Positioning System and were then imported into a geodatabase in ArcGIS which was used to estimate the area degraded. Data was obtained from 60 purposively sampled respondents from two communities fringing the reserve and 10 key informant interviews. Increased income (13%, employment opportunities (6.7% and increased market activities (2% were some benefits of the illegal mining activities identified by the respondents. Eight respondents associated their employment with of the advent of illegal mining activities out which 6 (70% were engaged directly in mining activities, while 2 (30% were into trading. The miners earned cash income range of US $ 2.9–22.9 daily. Within 5 years, illegal mining had degraded 2.5 km2 (4.4% of the total area of the reserve and the destruction of cocoa farms and water sources (31. Farming among respondents reduced from 90% to 76% after illegal mining. The relatively high cost (US$ 6424.1 involved in flushing out and the subsequent return of such miners poses a threat to sustainable forest management and requires a more holistic approach in tackling such a problem.

The study uses Political–Economical-Social– Technological Analysis (PEST technique to evaluate opportunities and threats associated with external as well as internal factors influencing the firm. The study designs a questionnaire in Liket scale and asks decision maker to evaluate internal/external threats. In terms of external factors, there are four opportunities and ten threats associated with External factor evaluation (EFE factors. 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. The study determines the present and ideal status of the firm.

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

    The Secretary of the Interior has been requested to approve an exploration permit and mining lease which are part of a uranium exploration, mining, and milling Agreement, negotiated between the Navajo Tribe and the Exxon Corporation. The exploration area is a 400,000 acre tract located on the Navajo Reservation in San Juan County, New Mexico. If uranium ore in sufficient quantities to warrant development is discovered, Exxon is authorized to take a total of 51,200 acres to lease for mining, of which only 5,120 surface acres may be used for mining and milling purposes. While all exploration and predevelopment costs prior to mining must be borne by Exxon, the Navajo Tribe has reserved the right to participate in the venture on either a royalty basis or as a partner holding up to a 40 percent working interest. Impacts resulting from exploration will include disturbance of soils and vegetation and air quality degradation resulting from the vehicular movement and the operation of drilling equipment. If mining and milling takes place significant environmental impacts include: sub-surface water depletion, soils and vegetation disturbance, air quality degradation, interruption of the wildlife habitat, population increases, increased demands on community services and facilities, and disruption of established lifestyles and social patterns. Low levels of radioactive emissions will be found at mine and mill sites. Income and employment opportunities from the project to the Navajo Tribe, Navajo people, and the entire San Juan County community will be significant

    Full Text Available Kinetic parameters for the adsorption of nickel were studied in the waste CalcinationPlant Company Ernesto Che Guevara biomass Phyllanthus orbicularis synthetic and industrial waste Calcination Plant enterprise solutions. The results showed that the major factors influencing the adsorption capacity of the biomass increases with increasing pH and the initial concentration of nickel in the effluent and is reduced by increasing the biomass concentration. Meanwhile, the removal efficiency of residual nickel increases with increasing pH and concentration of biomass and reduced when the initial concentration of nickel in the effluent increases. The adsorption capacity nickel biomass Phyllanthus orbicularis from synthetic solutions and industrial waste Calcination Plant Company Nickel "Comandante Ernesto Che Guevara" was 44,05 and 26,25 mg/g respectively. The adsorption process nickel biomass Phyllanthus orbicularis follows kinetics pseudo-second order and according to the values of free energy of adsorption obtained through model-RadushkevichDubinin was 267,26 kJ/mol, this nature demonstrates that corresponds to a process mediated by chemical adsorption where the formation of stable bonds between the functional groups present in the biomass and the metal ions predominates.

    Reid, J.A.F.; Robertson, B.

    1982-01-01

    In 1966 an intensive exploration programme was conducted by Rio Tinto South Africa Ltd, involving airborne and ground radiometric surveys, percussion and diamond drilling, and pilot-plant tests. This investigation established the presence of a large deposit of low-grade uranium that could be mined on a large scale by open-pitting. Soon after production started in June 1974, it was realized that the original presentation of the ore reserves did not give a true reflection of the orebody. A comparison between the estimates and the ore mined from reserve blocks over the period 1975 to 1977 showed that the reserve grades were over-optimistic. In 1977 Rio Tinto Zinc Consultants were commissioned to re-evaluate the ore reserves from exploration diamond-drill data with the help of The Centre de Geostatistique at Fontainebleau, France. A new global reserve using disjunctive kriging techniques was developed, and is now the long-term reserve used for planning purposes at the Roessing Mine. For short-term planning, ore-reserve data are replaced by information from an intermediate drilling programme and blast-hole assays if these are available. A computerized short-term planning system has been established that reconciles the ore mined against the reserve blocks, as well as a system by which composited blast-hole assays are analysed for grade-control purposes. Owing to the complexity of the orebody, additional monitoring is achieved by the scanning of each truckload of ore with a group of scintillation crystal heads that evaluate the material mined

    2015-12-01

    Full Text Available The aim of this paper is to analyze the asset structure and the coverage of gross technical reserves of the Insurance – Reinsurance Company Astra SA, for the period 2003 – 2014. Insurance companies are required to constitute technical reserves, in order to cope with the payment obligations to policyholders. These reserves may only be covered on account of certain assets, admitted by law. In Romania, Orders No. 8 and 9/2011, issued by the Insurance Supervisory Commission, contain Rules regarding the assets admitted to cover gross technical reserves, the dispersion of assets admitted to cover gross technical reserves and the liquidity coefficient. Order No. 9/2011, relating to general insurance, has been amended by Rule No. 22/2014. In this paper, we have analyzed the main elements of Astra’s assets, their share in total assets and we have calculated the coverage of gross technical reserves by total assets and liquid assets. In 2013 and 2014, the value of total assets was below the value of gross tehnical reserves, which demonstrated Astra’s financial instability, through negative capital and the inability to meet the obligations to policyholders. Failure to comply with the prudential indicators has been one of the main causes of Astra`s bankruptcy.

    2016-01-01

    We examine the role proved reserves and production play in the market capitalization of publicly traded oil and gas companies engaged in the exploration and production of hydrocarbons. The paper provides two important contributions to the literature. First, we extend the existing research by utilizing the method of Robust Least Squares to estimate a multivariate market capitalization model that controls for firm type. Second, we document the impacts that oil and gas reserves to production ratios have on market capitalization. This is a key finding in the context of discounted net cash flow models and the findings suggest there is an optimal tradeoff between current and future production, given current volumes of reserves, the latter of which is valued positively by the market. Moreover, this optimal tradeoff or the optimal profit-maximizing intertemporal production choice is unique to the type of hydrocarbon being considered. Additionally, our findings highlight the importance of capital structure in the heavily capital intensive oil and gas industry. The results from this research should benefit both oil and gas companies and investors. Specifically, the results provide new and robust information as to the empirical relationships between key determinants of oil and gas company market valuations. - Highlights: • We utilized Robust Least Squares to estimate a multivariate market capitalization model. • There is a differential impact that oil and gas reserves to production ratios have on market capitalization. • The optimal profit-maximizing intertemporal production choice is unique to the type of hydrocarbon being considered. • Results provide new information as to the relationships between key determinants of oil and gas company market valuations.

    Costs and savings of child health services were studied in a private mining company in Peru. Despite considerable outlays for medical services, few children under age 5 were vaccinated, and half of their illnesses went untreated. Children who were attended at the company clinic usually received unnecessary medication. As a result of the study, the company hired additional staff to provide integrated maternal-child preventive health care and family planning and contracted for intensive training and periodic on-site supervision. In less than 2 years, vaccination coverage reached 75%, and virtually all children under age 1 were enrolled in growth monitoring. Prescriptions were reduced by 24%, including a 67% drop in antimicrobials. The cost of the new services was $13,200 for the first 2 years. Approximately $6800 has been saved in pharmaceuticals prescribed for respiratory infection and diarrhea. Recently, two more mines adopted maternal and child health and family planning services. It is hoped that cost-benefit arguments will encourage other companies to incorporate aggressive child survival measures into their health plans.

  4. New global realities for mining and exploration companies in today's world

    This paper presented brief comments on the stock market, the economy and the business of mining industry consolidation. It also described the rapidly changing environment within the mining industry and the realities facing mineral resource exploration and development. The mining industry is market-driven. Mining stocks have done well recently, with most movement occurring with major mining companies, particularly gold. However, it was noted that current economic projects have wide ranges of possible errors because the world has become a riskier place in recent months. In 2001, world trade growth slowed to just under 1 per cent, the lowest level since 1982, and global GDP growth fell to 2.4 per cent, a recessionary rate. The GDP grew strongly in China, the world's second largest consumer of mineral-based products. The author suggested that the state of economic recovery in 2002 will depend on how the major industrial economies respond to monetary easing and on how financial and currency markets manage stresses arising from increased levels of indebtedness. It is likely that demand for mineral commodities will be slow and keeping a close control on supply will determine how soon producers will benefit from world economic recovery

    Brown coal is of significant importance as a raw material to the Czech Republic as a result of increasing energy demands. It is the primary fossil fuel of homes in the Czech Republic, without which it would become fully dependent on energy source imports. Founded in 1994, the Severoceske doly a.s. company is the greatest mining company of the Czech Republic. The Severoceske doly, a.s. Chomutov joint stock company mining is drawn up in open pit mines and uses continual technology with excavators, long distance conveyers, and stackers. Large area external and internal dumps remain after the final stages of mining and quarrying. This paper summarized the basic facts about Severoceske doly a.s mining company, with particular reference to revitalization and restoration activities. The paper focused on restoration efforts in the Bilina Mines localities and Nastup Tusimice Mines, and on modern restoration methodology, and the application of research and science. It was concluded that a solution can be found that would fundamentally limit negative impacts to the landscape of brown coal areas using knowledge of rock characteristics relocated by mining and all the relationships in the area's surroundings. 4 refs., 2 tabs., 2 figs.

    2011-01-01

    The effect of uncertainty sources to the stochastic optimization of the combined project of a new surface lignite mine exploitation and power plant operation for electricity generation is investigated. Major sources of uncertainty that were considered are the reserves and the quality of the lignite. Since probability distribution functions for these uncertainties were estimated during the detailed exploration phase of the deposit, the overall goal is then to determine the optimal capacity of the power plant and consequently the optimal production rate of the mine over the time. The optimization objective that was selected is the maximization of the net present value of the project. Emphasis is placed on the sensitivity analysis for the investigation of the effect of quality and reserves uncertainty on project optimization, on the mathematical formulation of risk attitude strategy and on increasing the efficiency of the optimization process by creating a limited set of feasible solutions applying empirical rules. The developed methodology was applied for the determination of the optimal annual production rate of a new surface lignite mine in the area of Ptolemais–Amynteon in Northern Greece. - Highlights: ► Quality and reserves uncertainty affects considerably the production scheduling. ► Stochastic optimization is greatly accelerated by incorporating Taylor's rule. ► Decisions can be made considering different risk level attitudes.

    2009-01-01

    Continually rising energy prices in global markets highlights a serious concern about the need to improve energy efficiency and the efficiency in energy sector in many countries. China, as one of the fastest growing countries in the world and the largest coal producer, has high coal consumption but a low recovery rate of coal utilization. Coal efficiency and the efficiency in coal industry have therefore attracted a great deal of attention from Chinese policy makers, coal firms and academics. This study attempts to compare the relative technical efficiency performance of listed coal mining companies in China and the US using CCR and BCC models in the advanced DEA linear programming. The results show that the level of relative efficiency in Chinese coal mining enterprises, regardless of total technical efficiency or decomposed pure technical and scale efficiency, is much lower than in American coal firms. The study also highlights the input resources that cause the inefficiency of Chinese coal mining companies. Furthermore, in-depth discussion and analysis of how the institutional environments of the two countries could cause the differences are provided. (author)

    International Nuclear Information System (INIS)

    1994-09-01

    This booklet summarizes the history of the mining activity in the Lozere district (France) devoted to the extraction of uranium ores. This activity started in 1957 with the open cast exploitation of the Cellier deposit which lasted 35 years and produced 4200 t of uranium from 5800000 t of ore. The exploitation was performed by the French Company of Uranium Ores (CFMU). The uranium crisis started in 1962 and led to an increase of prospecting activities. The crisis ended with the first oil crack in 1973 and the uranium demand and prices grew up until 1979 when the Three Mile Island reactor accident occurred. The second crisis that followed led to the development of new recovery processes such as the heap lixiviation process. In 1980, the CFMU became the French Company of Mokta (CFM) and in 1986, the CFM became a 100% daughter company of the Cogema group. The exploitation of the Bondons mine ended in 1989 and the program of site rehabilitation started. The document focusses on the environmental aspects of this program, the reforestation, the drainage of surface waters and the control of water quality. (J.S.)

    R Bakery company is a company that produces bread every day. Products that produced in that company have many different types of bread. Products are made in the form of sweet bread and wheat bread which have different tastes for every types of bread. During the making process, there were defects in the products which the defective product turns into reject product. Types of defects that are produced include burnt, sodden bread and shapeless bread. To find out the information about the defects that have been produced then by applying a designed model business intelligence system to create database and data warehouse. By using model business Intelligence system, it will generate useful information such as how many defect that produced by each of the bakery products. To make it easier to obtain such information, it can be done by using data mining method which data that we get is deep explored. The method of data mining is using k-means clustering method. The results of this intelligence business model system are cluster 1 with little amount of defect, cluster 2 with medium amount of defect and cluster 3 with high amount of defect. From OLAP Cube method can be seen that the defect generated during the 7 months period of 96,744 pieces.

  15. The Practice of Mining Companies in Building Relationships with Local Communities in the Context of CSR Formula

    2013-01-01

    Full Text Available This paper presents results regarding the analysis of activities of coal mining companies operating in Poland in terms of Corporate Social Responsibility (CSR, with a particular emphasis focused on the area of community involvement. This sphere is extremely important for entities operating in the sector due to the scale of the impact on the social environment and the potential threat of resistance from local communities. Mining companies have developed forms of action in this area and are subject to a number of legal regulations, especially in such critical points as mining damages or acquiring concessions for mining operations. Therefore, it is worth analysing these issues from the perspective of the CSR formula, and the way in which mining companies build a relationship with stakeholder groups which are undoubtedly the local communities. This represents a specific challenge for mining companies and requires a change in management approach based on the acceptance of responsibility for the impact they have and to seek solutions that will benefit both the companies themselves and their surroundings. It should also affect the change in approach for building relationships with local groups beyond just the legal requirements.

    In the practice of mining companies, the vast majority of them produce more than one product. The analysis of the break-even, which is referred to as CVP (Cost-Volume-Profit) analysis (Wilkinson, 2005; Czopek, 2003) in their case is significantly constricted, given the necessity to include multi-assortment structure in the analysis, which may have more than 20 types of assortments (depending on the grain size) in their offer, as in the case of open-pit mines. The article presents methods of evaluation of break-even (volume and value) for both a single-assortment production and a multi-assortment production. The complexity of problem of break-even evaluation for multi-assortment production has resulted in formation of many methods, and, simultaneously, various approaches to its analysis, especially differences in accounting fixed costs, which may be either totally accounted for among particular assortments, relating to the whole company or partially accounted for among particular assortments and partially relating to the company, as a whole. The evaluation of the chosen methods of break-even analysis, given the availability of data, was based on two examples of mining companies: an open-pit mine of rock materials and an underground hard coal mine. The selection of methods was set by the available data provided by the companies. The data for the analysis comes from internal documentation of the mines - financial statements, breakdowns and cost calculations.

    Full Text Available Abstract Sustainable procurement is a solution to integrate environmental and social considerations in all steps of procurement process, in order to reduce impacts on human health, environment, and human rights. Despite the existence of important works in this area, more studies for determining how the principles related to sustainable development can be integrated to procurement strategies are needed. This study presents a case study in a mining company to evaluate the elements that should be considered for the implementation of sustainability concept in the contracting of services through the application of a sustainability portfolio model. Results show that the contracts of the internal movement's category of the studied company fit as Strategic Commodity, which means that the items in this category have a risk in the strategic supply, because they need investments made by the buyer in the relationship with the supplier.

    2017-01-01

    Nowadays, the appetite for the investment and mergers and acquisitions (M&A) activity in RFID companies is growing rapidly. Although the huge number of papers have addressed the topic of business valuation models based on statistical methods or neural network methods, only a few are dedicated to constructing a general framework for business valuation that improves the performance with network graph (NG) and the corresponding community mining (CM) method. In this study, an NG based business valuation model is proposed, where real options approach (ROA) integrating CM method is designed to predict the company's net profit as well as estimate the company value. Three improvements are made in the proposed valuation model: Firstly, our model figures out the credibility of the node belonging to each community and clusters the network according to the evolutionary Bayesian method. Secondly, the improved bacterial foraging optimization algorithm (IBFOA) is adopted to calculate the optimized Bayesian posterior probability function. Finally, in IBFOA, bi-objective method is used to assess the accuracy of prediction, and these two objectives are combined into one objective function using a new Pareto boundary method. The proposed method returns lower forecasting error than 10 well-known forecasting models on 3 different time interval valuing tasks for the real-life simulation of RFID companies.

  20. Effect of Local Community’s Environmental Perception on Trust in a Mining Company: A Case Study in Mongolia

    2018-02-01

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

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

    Ranking of workplaces with respect to working conditions is very significant for each company. It indicates the positions where employees are most exposed to adverse effects resulting from the working environment, which endangers their health. This article presents the results obtained for 12 different production workplaces in the copper mining and smelting complex RTB Bor - 'Veliki Krivelj' open pit, based on six parameters measured regularly which defined the following working environment conditions: air temperature, light, noise, dustiness, chemical hazards and vibrations. The ranking of workplaces has been performed by PROMETHEE/GAIA. Additional optimization of workplaces is done by PROMETHEE V with the given limits related to maximum permitted values for working environment parameters. The obtained results indicate that the most difficult workplace is on the excavation location (excavator operator). This method can be successfully used for solving similar kinds of problems, in order to improve working conditions.

    1978-02-01

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

    Full Text Available This paper describes the two-step method used to analyse the factors and aspects influencing human error during the maintenance of mining machines. The first step is the cause-effect analysis, supported by brainstorming, where five factors and 21 aspects are identified. During the second step, the group fuzzy analytic hierarchy process is used to rank the identified factors and aspects. A case study is done on mining companies in Serbia. The key aspects are ranked according to an analysis that included experts who assess risks in mining companies (a maintenance engineer, a technologist, an ergonomist, a psychologist, and an organisational scientist. Failure to follow technical maintenance instructions, poor organisation of the training process, inadequate diagnostic equipment, and a lack of understanding of the work process are identified as the most important causes of human error.

    Full Text Available The article is concerned with developing a model of the effective management of reserve capital of an endowment insurance company or so-called endowment life insurance. Such companies are powerful actors at the international market, operate with considerable capital and are effective as active investors in different areas. The main features of functioning of endowment insurance companies, as well as the factors that guarantee the sustainable development of insurance companies in both the global and Ukrainian markets, were considered. The principles of management of financial resources of insurance companies were studied. An elaborated model of management of current and reserve capital has been provided, the mechanism for establishing and operating the insurance company’s current capital, taking into account the process of income of insurance premiums and the payment of dividends on poles, has been described. An analysis of the largest endowment insurance companies in the Ukrainian market was carried out. Based on the analysis, the recommended discount rate has been calculated for the model proposed in the article.

    Petra F. A. Dilling

    2016-09-01

    Full Text Available This study empirically analyzes reporting on long-term value creation for Canadian public mining and energy companies. It represents an important first step in determining the quality of reporting and its determinants for large public companies. In this exploratory empirical study, a reporting quality scoring index was developed to measure disclosure quality of long-term value creation reporting. Content analysis was used to examine financial and sustainability reports for a sample of twenty Canadian public mining and energy companies. Corporate disclosure quality scores were then calculated by assessing the quality of reporting in four main categories. The findings suggest that overall disclosure quality on long-term value creation is still low. Companies disclosing higher quality information on long-term value creation are of bigger size, operate in the basic materials sector, have an independent board, are listed in the Dow Jones Sustainability Index, experience higher stock volatility and use more words related to long-term value creation in their annual financial and non-financial reports. In order to increase and restore stakeholder trust and credibility as well as a tool to maintain stability, it is strongly recommended to introduce adequate mandatory standardization resulting in a set of internationally recognized reporting standards as well as a requirement for external assurance of reports.

  19. Estimation of the Cost of Equity for Mining Companies Using the P-Lefac Method

    Science.gov (United States)

    Ranosz, Robert

    2014-03-01

    This article describes one of the methods of estimating the cost of equity, namely the LEFAC method. The name of the method is an acronym of the names of individual financial categories: L - Liquidity, E - Earnings, F - Franchise, A - Assets, C - Capital. It is a scoring method similar to the way used by ING Financial Markets to estimate share prices. A review of literature shows that this method is not widely known and used by enterprises, but it has certain advantages which justify its use. Its main advantages include its easy use and the stability of the results obtained: the calculated cost of equity is never lower than the adopted risk-free rate. The method is particularly useful for companies (enterprises) not listed on stock exchanges. This article is divided into five parts: an introduction, the LEFAC method, the parameterization of the LEFAC method (P-LEFAC), an example calculation and a summary. The second part of this article characterises the LEFAC method. In the third part, the method is parameterized to obtain a function described by formula 22. The following section contains an example calculation for KGHM S.A. and also presents results which mining companies would achieve if they used the discussed method to calculate the cost of their equity. The calculations were performed for mining companies listed on the Warsaw Stocks Exchange and unlisted ones. This part of the article also contains a short comparison of results obtained using the CAPM method and the discussed model. The last section consists of a summary presenting final conclusions. The article ends in a list of the literature referred to. Niniejszy artykuł został poświęcony jednej z metod szacowania kosztu kapitału własnego, a mianowicie metodzie LEFAC. Nazwa metody pochodzi od pierwszych liter wyrazów z języka angielskiego, które określają poszczególne kategorie finansowe: L - Liquidity (płynność), E - Earnings (zyski), F - Franchise (strategia), A - Assets (aktywa), C

  20. An empirical study on the critical success factors of small to medium sized projects in a South African mining company

    Directory of Open Access Journals (Sweden)

    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.

    Full Text Available Currently, strongly increasing globalization forces companies around the world to search new ways to build competitive advantage and achieving goals. Society having wider access to information and products, began to pay attention not only to the attractiveness of the goods, but also to the credibility of the environmental and social of functioning companies. This makes, that the concept of corporate social responsibility and the green revolution, which are strongly associated with innovations, in last years become widely discussed in the literature, as well as popular in the activities of enterprises. This article is an attempt to answer the question, whether the combination of these three elements is a guarantee for the creations of a positive image, and thus the value of a modern and strong company. The research literature aims to identify the current approach to these three factors and their characteristics. In contrast, the analysis of Polish hard coal mining sector indicates the role of innovation, environmental protection and CSR in the industry - whether the actions in this area are present and to what extent. In addition, it will be presented to outline the current state of Polish hard coal mining sector

    The article specifies measuring data of air parameters and its volume flow in the shafts and on the surface, collected in BKPRU-2 (Berezniki potash plant and mine 2) («Uralkali» PJSC) in normal operation mode, after shutdown of the main mine fan (GVU) and within several hours. As a result of the test it has been established that thermal pressure between the mine shafts is active continuously regardless of the GVU operation mode or other draught sources. Also it has been discovered that depth of the mine shafts has no impact on thermal pressure value. By the same difference of shaft elevation marks and parameters of outer air between the shafts, by their different depth, thermal pressure of the same value will be active. Value of the general mine natural draught defined as an algebraic sum of thermal pressure values between the shafts depends only on the difference of temperature and pressure of outer air and air in the shaft bottoms on condition of shutdown of the air handling system (unit-heaters, air conditioning systems).

    Emerson, L.D.

    1999-01-01

    Mountaintop Mining has been practiced in West Virginia and surrounding Central Appalachian states for over twenty years. In recent months, however, media coverage and other events have increased public and regulatory scrutiny of the practice, which has led to mine permitting delays and employee layoffs. A law suit was filed in federal court alleging, among other things, that the construction of valley fills for excess spoil disposal is a violation of the Clean Water Act. West Virginia's Governor appointed a Task Force to study the issue and has made recommendations for further regulations. Arch Coal, Inc., operates four large surface mines in West Virginia, and many of it's mining subsidiaries have won federal and state honors for excellence in reclamation. Arch has also funded several studies that address many of the issues that have been at the core of the public debate. One study involves the assessment of the long term impact of large scale mining and valley fills on downstream water quality and aquatic life. Another evaluates the rate of forest plant invasion onto reclaimed lands. A third study compares the value of the wildlife habitats created on reclaimed lands relative to undisturbed ridge top and stream side habitats. The results of these studies show that mountaintop removal mining, when done responsibly, has minimal impacts on the environment, and can in fact provide valuable lands for future development. Arch Coal, Inc., has taken a leading role in addressing the scientific and public policy aspects of this controversial issue

    Aeromagnetic data belonging to the State Company of Geology and Mining of Iraq (GEOSURV) have been recovered from magnetic tapes and early paper maps. In 1974 a national airborne survey was flown by the French firm Compagnie General de Geophysique (CGG). Following the survey the magnetic data were stored on magnetic tapes within an air conditioned archive run by GEOSURV. In 1990, the power supply to the archive was cut resulting in the present-day poor condition of the tapes. Frontier Processing Company and the U.S. Geological Survey (USGS) have been able to recover over 99 percent of the original digital data from the CGG tapes. Preliminary reprocessing of the data yielded a total magnetic field anomaly map that reveals fine structures not evident in available published maps. Successful restoration of these comprehensive, high quality digital datasets obviates the need to resurvey the entire country, thereby saving considerable time and money. These data were delivered to GEOSURV in a standard format for further analysis and interpretation. A parallel effort by GETECH concentrated on recovering the legacy gravity data from the original field data sheets archived by IPC (Iraq Petroleum Company). These data have been compiled with more recent GEOSURV sponsored surveys thus allowing for the first time a comprehensive digital and unified national gravity database to be constructed with full principal facts. Figure 1 shows the final aeromagnetic and gravity data coverage of Iraq. The only part of Iraq lacking gravity and aeromagnetic data coverage is the mountainous areas of the Kurdish region of northeastern Iraq. Joint interpretation of the magnetic and gravity data will help guide future geophysical investigations by GEOSURV, whose ultimate aim is to discover economical mineral and energy resources. ?? 2011 Society of Exploration Geophysicists.

    The present work is to show the application and implementation of the algorithms and models proposed in part I. It also represents the simulation results of (a) extracting a lumped financial model (the aggregated model) of the distribution system with distributed generations (DGs) and interruptible loads (ILs), (b) distribution company's (DISCO's) process of decision-making, based on the created financial model, on allocating its generating capability for internal usage and proposing to the hourly-ahead energy and reserve markets, and (c) a profit-based network reconfiguration methodology that increases the DISCO's technical ability and directs its financial affairs towards more profitable transactions in the upcoming markets. The function of the algorithms used for detecting unfeasible configurations, namely loop path and/or isolated part in the network are shown and well exemplified. Influential factors in DISCO's generating capability and in the coefficients of DISCO's internal cost function (ICF) are investigated. The present study substantiates the ICF-based optimization method by comparing the relevant results with the results obtained based on the use of total cost function (TCF). Several scenarios on market prices of energy and reserve and on the contingency probability factor pertaining to the real-time generation in reserve market are considered. Simulation results indicate that getting more economical benefits, DISCO may necessarily play different roles in the market and change the network configuration, at different hours.

    This work presents a novel hourly-ahead profit model for an active distribution company (DISCO), a DISCO with high capacity level of connected DGs that can make selling proposals for the markets, in a pool-based system. The presented model engages DSICO in both energy producing and reserve providing activities. DISCO's earnings from reserve market include the remuneration both for real-time generation and ready-for-service capacity. To achieve the optimal decisions for an active DISCO in the energy and reserve markets, a two-stage optimization model and associated mathematical formulations have been developed. The first subproblem extracts a single operating profile (a lumped financial model) of the whole distribution system, including DGs and ILs, at the connecting point to the upstream network. The second one determines the optimal values of decision variables (power and reserve commodities) to maximize the DISCO's profit, in case such variables are accepted in the markets. In other words, it aims to optimally allocate the DISCO's generating capability for proposing into the energy and reserve markets, from the DISCO's perspective. It also proposes a profit-based network reconfiguration methodology for a multi-substation multi-feeder DISCO to increase DISCO's ability to gain more benefits from the market activities. It conducts DISCO's generating capabilities towards the proper substations to reap more probable benefits. It also introduces fast, simple, and straightforward algorithms for recognition and removal of configurations having loop and/or islanding parts in. Simulation results are given at the second part of the present work.

    The Compagnie Generale des Matieres Nucleaires is currently exploiting several steep vein uranium deposits in France. The upper parts are exploited using the open-cast method, in the lower parts underground mining is used. The veins with a thickness of several meters fill faults caused by tectonic activity. With regard to the low strength of the rocks, wooden supports are used or fills. In the course of the past 25 years several mining methods have been tried of which overhand stoping was selected with an oblique ramp driven in the ore, this mainly for securing operating safety and the profitability of selective exploitation. In overburdens with a low bearing capacity the method of underhand benching in slices was used with a concrete fill and later underhand benching in slices with concrete reinforcing plates. Overhand stoping is being tried with fill and electric self-propelled machines left in the stope and mechanized driving of raises by full profile drilling. (B.S.)

    Sieg, Tobias; Kreibich, Heidi; Vogel, Kristin; Merz, Bruno

    2017-04-01

    The assessment of vulnerability gained more and more attention in flood risk research during the recent years. However, there is still not much knowledge available about flood vulnerability of companies and its influencing factors. This study follows the natural sciences concept which defines vulnerability as the degree of loss to a given element at risk resulting from flooding of a given magnitude. Machine learning algorithms like Random Forests (RFs) are promising approaches, since they consider many influencing variables and as such allow for a detailed assessment of flood vulnerability. Only these variables which are meaningful for the differentiation of a certain target variable are used by the derived models. This allows for an identification of relevant damage influencing variables and hence for a more detailed picture of flood vulnerability of companies. This study aims to identify relevant damage influencing variables by means of the variable importance provided by Random Forests. The data sets used are taken from two surveys conducted after the floods in the Elbe and Danube catchments in the years 2002 and 2013 in Germany. Damage to buildings (n = 430), equipment (n = 651) as well as goods and stock (n = 530) are taken into account. The analysis is done for the entire data set as well as for four groups of different company sectors and the corresponding data subsets. Relevant damage influencing variables separated by sector and assets are identified as, for example, the degree of contamination or precautionary measures undertaken before the flood event. The results provide insight into the damage processes and improve data-acquisition in future surveys by, for instance, asking specific questions for company sectors and assets.

    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.

    Full Text Available HIV impacts heavily on the operating costs of companies in sub-Saharan Africa, with many companies now providing antiretroviral therapy (ART programmes in the workplace. A full cost-benefit analysis of workplace ART provision has not been conducted using primary data. We developed a dynamic health-state transition model to estimate the economic impact of HIV and the cost-benefit of ART provision in a mining company in South Africa between 2003 and 2022.A dynamic health-state transition model, called the Workplace Impact Model (WIM, was parameterised with workplace data on workforce size, composition, turnover, HIV incidence, and CD4 cell count development. Bottom-up cost analyses from the employer perspective supplied data on inpatient and outpatient resource utilisation and the costs of absenteeism and replacement of sick workers. The model was fitted to workforce HIV prevalence and separation data while incorporating parameter uncertainty; univariate sensitivity analyses were used to assess the robustness of the model findings. As ART coverage increases from 10% to 97% of eligible employees, increases in survival and retention of HIV-positive employees and associated reductions in absenteeism and benefit payments lead to cost savings compared to a scenario of no treatment provision, with the annual cost of HIV to the company decreasing by 5% (90% credibility interval [CrI] 2%-8% and the mean cost per HIV-positive employee decreasing by 14% (90% CrI 7%-19% by 2022. This translates into an average saving of US$950,215 (90% CrI US$220,879-US$1.6 million per year; 80% of these cost savings are due to reductions in benefit payments and inpatient care costs.

    Full Text Available Orientation: Human resource practices influence the psychological contract between employee and employer and, ultimately, organisational performance. Research purpose: The objective of this study was to examine the effect of human resource practices on the types of psychological contracts in an iron ore mining company in South Africa empirically. Motivation for the study: Although there have been a number of conceptual studies on the effect of human resource practices on psychological contracts, there has been no effort to synthesise the links between these contracts and various human resource practices systematically. This study endeavoured to provide quantitative evidence to verify or refute conceptual studies on this relationship. Its findings could inform human resource strategies and, ultimately, the prioritisation of human resource practices to improve the cost-effective allocation of resources. Research design, approach and method: The researchers administered two questionnaires. These were Rousseau’s Psychological Contract Inventory (2000 and the Human Resource Practices Scale of Geringer, Colette and Milliman (2002. The researchers conducted the study with 936 knowledge workers at an iron ore mining company in South Africa. They achieved a 32% response rate. Main findings: The findings showed that most participants have relational contracts with the organisation. Another 22% have balanced contracts, 8% have transitional contracts whilst only 1% have transactional contracts. The study suggests that there are relationships between these psychological contracts and specific human resource practices. The study found that training and development was the most important human resource practice for developing relational and balanced contracts. Employees thought that they contributed more than their employer did to the relationship. The researchers developed a model to illustrate the influence of the various human resource practices on

    In oil sands production, abrasive sands and gases such as hydrogen sulfide (H{sub 2}S) can cause corrosion and equipment failure. This article presented details of Hardide, an ultra-hard coating technology that is well-suited to the harsh operating environments of Alberta's heavy oil and oilsands projects. The Hardide manufacturing process involves the application of a thin surface coating of tungsten carbide by chemical vapour deposition to customer-supplied components that are then heated to between 500 degrees C and 600 degrees C, depending on the substrate and the application. Once at the desired temperature, a mixture of gases is pumped into the furnace, where a chemical reaction takes place which then crystallizes on the components to produce a layer of binder-free tungsten carbine coating with abrasion, erosion and chemical resistant characteristics. The coating can be applied to steel, alloys and other materials and has a coating capacity that ranges from 5 to 100 microns. Research on the coating started at the University of Moscow and the Russian Academy of Science Institute but was halted due to the financial problems which followed Perestroika. The coating is now used in the aerospace, power, chemical and food manufacturing industries. It was concluded that the technology is being considered by a number of Canadian oil and gas companies. 2 figs.

    Full Text Available This paper seeks to establish the relationships between three job characteristics constructs, namely work engagement, intrinsic motivation and job satisfaction in a workplace notorious for discord and conflict between workers and employers. A quantitative methodology was adopted using a cross-sectional survey. Respondents were selected from the workers at a mining company, with a final sample of 156 employees participating in the study. The Utrecht Work Engagement Scale, Intrinsic Motivation Inventory and the Minnesota Job Satisfaction Questionnaire were used to collect data. The results of the study indicate positive relationships between job satisfaction, work engagement and intrinsic motivation among the workers. Age and marital status were found to be significant contributors to workers’ job satisfaction, intrinsic motivation and work engagement. Implications of these results are that human resource interventions are required in order to deal with enhancing work engagement, intrinsic motivation and job satisfaction. Furthermore, the results indicate that intrinsic motivation and work engagement can enhance job satisfaction. The current study adds to the research pointing at job satisfaction as a promising underlying mechanism for employees’ to be internally motivated and engaged at work.

    Local exhaust ventilation (LEV) systems and integrated collectors were designed and implemented in a mining company in order to control emitted air pollutant from furnaces. The LEV was designed for capture and transition of air pollutants emitted from furnaces to the integrated collectors. The integrated collectors including four high efficiency Stairmand model cyclones for control of particulate matter, a venturi scrubber for control of the fine particles, SO(2) and a part of H(2)S to follow them, and a packed scrubber for treatment of the residual H(2)S and SO(2) were designed. Pollutants concentration were measured to determine system effectiveness. The results showed that the effectiveness of LEV for reducing workplace pollution is 91.83%, 96.32% and 83.67% for dust, SO(2) and H(2)S, respectively. Average removal efficiency of particles by combination of cyclone and venturi scrubber was 98.72%. Average removal efficiency of SO(2) and H(2)S were 95.85% and 47.13% for the venturi scrubber and 68.45% and 92.7% for the packed bed scrubber. The average removal efficiency of SO(2) and H(2)S were increased to 99.1% and 95.95% by the combination of venturi and packed bed scrubbers. According to the results, integrated collectors are a good air pollution control option for industries with economic constraints and ancient technologies.

    This paper examines conflicts that occur between mining companies and civil society organizations (CSOs) around the world and offers an innovative analysis of mining conflicts from a social network perspective. The analysis showed that, as the number of CSOs involved in a conflict increased, its outcome was more likely to be perceived as a success in terms of environmental justice (EJ); if a CSO was connected to other central CSOs, the average perception of EJ success was likely to increase; and as network distance between two conflicts increased (or decreased), they were more likely to lead to different (or similar) EJ outcomes. Such network effects in mining conflicts have policy implications for EJ movements. It would be a strategic move on the part of successful CSOs to become involved in other major conflicts and disseminate information about how they achieved greater EJ success.

    Some mistakes in the evaluation of the proven reserves of Royal Dutch Shell group, the second world petroleum leader, will oblige the other oil and gas companies to be more transparent and vigilant in the future. The proven reserves ('P90' in petroleum professionals' language) are the most important indicators of the mining patrimony of companies. These strategic data are reported each year in the annual reports of the companies and are examined by the security exchange commission. The evaluation of reserves is perfectly codified by the US energy policy and conservation act and its accountable translation using the FAS 69 standard allows to establish long-term cash-flow forecasts. The revision announced by Shell on January 9 leads to a 20% reduction of its proven reserves. Short paper. (J.S.)

    2017-01-01

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

    The global economic crisis that started in 2007 in the area of finance, expanded over the subsequent years to the business sphere, and resulted in a drop of demand and production almost in any field of business activity. Access to foreign sources of finance, especially to loans, has become more difficult and expensive. In such circumstances, enterprises have had to resort more often to their own capital generated by the issue of shares, and to retained profit. Banks have limited their loans for business entities, reduced credit periods, and raised credit margins as well as their levels of collaterals. The McKinsey research into the changes that occur in the structures of sources of finance confirms that the share of equity capital in the structure of financing of non-financial enterprises has visibly grown, and their crediting scopes have been limited all over the European Union as well as in the euro zone. The global tendencies as regards directions of changes in the structure of the sources of corporate financing have also been reflected in Poland. The economic slowdown has resulted in changes in the structures of corporate financing. Mining companies have risen the shares of their equity capital in their general sources of financing. This tendency corresponds to the changes of structure of corporate financing in Poland and Europe. Enterprises have resorted to bank loans to a lesser degree than in times of better market situation. In mining, public companies have increased their crediting, while in private sector the tendency has been reverse. Enterprises tend to use more flexible debiting forms as compared to credits by way of issue of long-term corporate bonds. Mining companies have developed issue programs that are to be implemented over three-year periods. Before, only Katowicki Holding Węglowy [Katowice Mining Holding] had issued bonds. The present publication is an attempt at assessing the changes in the structure of corporate financing within the mining

    A Canadian company has recently received approval to develop large oil sands mining operations in Utah. Earth Energy Resources is now raising the finances required to commercialize its operations in the state. Utah's oil sands reserves are currently estimated at between 20 to 32 billion barrels. However, the impacts of oil sands operations are of concern to some environmental groups, who worry that Utah will become a duplicate of Alberta's Athabasca region. The planned project is a 2000 barrel-per-day pilot project. Regulators in Utah have received negative responses from the public after advertising the potential project in local newspapers, and demonstrations have been held in the state's capital. Oil sands are already being developed at 2 installations in Utah, with the bitumen currently being sold as asphalt products. The state is also home to significant oil shale reserves. Operators in the region plan to design compact, well-contained mines in order to maintain transportability. 3 figs.

    This study examined the strategic implications of mentoring relationships perceived by company-grade U.S. Army Reserve nurses. The effects of mentorship on professional socialization, job satisfaction, and intent to stay were examined using the adapted framework of Hunt and Michael. The study population consisted of U.S. Army Reserve nurses from all three components of the ready reserve. One hundred nurses from each category were randomly selected and provided a questionnaire. The questionnaire combined Dreher's Mentoring Scale, Price's Intent-to-Stay Scale, and Hoppock's Job Satisfaction Scale. The overall response rate was 57%. Seventy-two of the 171 respondents reported at least one mentored experience. Findings indicate that mentored nurses report more satisfaction and have a higher intent to stay than nonmentored nurses. Continued research and encouragement of mentoring are recommended.

  4. The strategic interaction between the government and international oil companies in the UK: An example of a country with dwindling hydrocarbon reserves

    International Nuclear Information System (INIS)

    Willigers, Bart J.A.; Hausken, Kjell

    2013-01-01

    The 2011 UK tax rise on hydrocarbon exploitation activities obviously increases short term tax revenues however the longer term effects are less clear. The strategic interaction between the UK government, a producer and a shipper has been analyzed in a game theoretical model. A complex interaction between players is expected given (1) dwindling resources and large decommissioning liabilities and (2) the fact that much of the hydrocarbons produced in the North Sea are exported through an infrastructure with shared ownership. The 2011 UK tax adjustment will most likely result in value destruction for the government, producers and shippers. Our analysis suggests that governments are unlikely to ultimately benefit from reducing their decommission liabilities at the expense of International Oil Companies. In countries with unstable tax regimes, such as the UK, International Oil Companies will adopt their strategies in anticipation of future tax changes. Their adopted strategy is a function of decommissioning liabilities and remaining reserves as well as whether they are producers, shippers or producers and shippers. The ultimate payoff of a government is a function of the remaining reserves and total decommissioning liabilities, but also depends on the distribution of these value metrics between producers and shippers. - Highlights: ► The 2011 UK hydrocarbon tax increase is likely to cause overall value destruction. ► Governments are unlikely to benefit from reducing their decommission liabilities. ► Differences in payoff functions of producers and shippers control the game. ► The distribution of reserves and decommissioning cost is a key factor in the game

    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.

    The aim of the article was to check if mindfulness based stress reduction (MBSR) is an effective intervention in reducing work-related stress in the case of workers of a copper mine. 66 employees were randomized to the experimental group (32 participants) or to the control group (34 participants). Work-related stress was measured using Job Content Questionnaire (JCQ) (Karasek, 1979) and mental health was measured using General Health Questionnaire (GHQ-28) (Goldberg, 1990). Experimental manipulation was 40-hour-long MBSR training. MANOVA has revealed significant increase of JCQ decision latitude (F=17.36, p=.00) and social support (supervisor. F=9.00, p<.004; coworker. F=5.61, p<.02), a significant decrease in GHQ anxiety (F=5.28, p<.079) and depression (F=3.95, p<.048) due to the intervention. The study confirms that MBSR can also be effective in reducing stress resulting from the external risk (and/or imagined fear) of losing one's health or life. The use of MBSR could be recommended in health & safety activities in difficult and dangerous work conditions, such as mining, to promote workers' well-being.

  11. US uranium reserves

    1981-01-01

    The current low level of demand, compounded by rapidly rising costs and low prices, has caused a significant reduction in drilling for uranium in the United States, and the trend is likely to continue for a few more years. The effect on uranium reserves will be fewer additions to reserves because less exploration is being done. Further reductions will occur, especially in low-cost reserves, because of increasing costs, continuing depletion through production, and erosion through the high grading of deposits to fulfill previous contractual commitments. During the past several years, it has been necessary to increase the upper reserve cost level twice to compensate for rising costs. Rising costs are reducing the $15 reserves, the cost category corresponding most closely to the present market price, to an insignificant level. An encouraging factor related to US uranium reserves is that the US position internationally, as far as quantity is concerned, is not bad for the longer term. Also, there is a general opinion that US consumers would rather contract for domestic uranium than for foreign because of greater assurance of supply. Still another factor, nearly impossible to assess, is what effect rising costs in other countries will have on their uranium reserves. The annual conferences between the Grand Junction Area Office staff and major uranium companies provide a broad overview of the industry's perception of the future. It is not optimistic for the short term. Many companies are reducing their exploration and mining programs; some are switching to other more marketable mineral commodities, and a few are investing more heavily in foreign ventures. However, there is general optimism for the long term, and many predict a growth in demand in the mid-1980s. If the industry can survive the few lean years ahead, rising prices may restore its viability to former levels

    Full Text Available In this study, a horizontal flow constructed wetland (HFCW planted with Typha angustifolia, was tested to bioremediation potential for arsenic from mine effluent under the natural climatic conditions in largest boron mine reserve area over the world, Kırka (Eskişehir. Briefly, the objective of the present experiment was to investigate arsenic bioremediation capability of wetland system and asses the phytoremediation efficiency of T. angustifolia, selected as a donor plant in this study, with different initial arsenic concentrations. Our results indicated that HFCW has capability to decreased arsenic in mine effluent from 49 µg L-1 to 21.8 µg L-1 in a period of 84 days, suggesting that HFCW could be a reasonable bio-filter option to control arsenic pollution directly from mining effluent in largest borax reserve over the world. Furthermore, we found that arsenic concentration in outflow samples was stably below 10 µg L-1 (drinking water safety limit with an inflow range from 42.3 to 42.1 arsenic µg L-1 during the first 28 days. Our results also indicated that belowground parts of T.angustifolia accumulate more arsenic from mine effluent compared to aboveground parts during experiment period. Therefore, we suggested that belowground parts of the plants in HFCW play an important role for arsenic bioremediation from mine effluent which origin of Kırka Borax reserve area. In this respect, bioconcentration factor (BCF for the plants which grown in HFCW was found higher than those of control group. Moreover, results of the present experiment also showed that relatively high level of arsenic retained in the filtration media of HFCW during the experiment period, indicating that filtration media which was used in HFCW has potential to filter arsenic from mine effluent. Consequently, the scientific insight of the present study is to present an innovative, cost effective, and easy operating method for arsenic remediation from mine effluent.

  13. Uranium mining

    International Nuclear Information System (INIS)

    2008-01-01

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

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

    1994-01-01

    On the occasion of the 500th return of the birthday of Georgius Agricola (1494-1555) the author, drawing on his own experience from decades of work in bismuth/uranium mining, celebrates this great Saxonian humanist, whose achievements influence even modern-day mining. The book spans the period of history from silver mining in the Saxonian Ore Mountains during Agricola's time to the period more than 400 years later when uranium was extracted at an unparalleled scale. As substantiated by the historical comparison, Agricola's mining science, the mining technology for which he laid the basis, were still applied even centuries later in bismuth mining. At the same time the book offers a critical review of the last great mining activities in the area, so momentous to man and the environment. (orig./HP) [de

  4. Mining with communities

    Veiga, Marcello M.; Scoble, Malcolm; McAllister, Mary Louise

    2001-01-01

    To be considered as sustainable, a mining community needs to adhere to the principles of ecological sustainability, economic vitality and social equity. These principles apply over a long time span, covering both the life of the mine and post-mining closure. The legacy left by a mine to the community after its closure is emerging as a significant aspect of its planning. Progress towards sustainability is made when value is added to a community with respect to these principles by the mining operation during its life cycle. This article presents a series of cases to demonstrate the diverse potential challenges to achieving a sustainable mining community. These case studies of both new and old mining communities are drawn mainly from Canada and from locations abroad where Canadian companies are now building mines. The article concludes by considering various approaches that can foster sustainable mining communities and the role of community consultation and capacity building. (author)

    1994-09-01

    This booklet summarizes the history of the mining activity in the Lozere district (France) devoted to the extraction of uranium ores. This activity started in 1957 with the open cast exploitation of the Cellier deposit which lasted 35 years and produced 4200 t of uranium from 5800000 t of ore. The exploitation was performed by the French Company of Uranium Ores (CFMU). The uranium crisis started in 1962 and led to an increase of prospecting activities. The crisis ended with the first oil crack in 1973 and the uranium demand and prices grew up until 1979 when the Three Mile Island reactor accident occurred. The second crisis that followed led to the development of new recovery processes such as the heap lixiviation process. In 1980, the CFMU became the French Company of Mokta (CFM) and in 1986, the CFM became a 100% daughter company of the Cogema group. The exploitation of the Bondons mine ended in 1989 and the program of site rehabilitation started. The document focusses on the environmental aspects of this program, the reforestation, the drainage of surface waters and the control of water quality. (J.S.)

    1987-01-01

    The purpose of this study is to determine which of these alternative annual report disclosures of oil and gas reserves, namely historic capitalized costs, quantities, and discounted cash flows contributes the most information content. Information content is defined as the ability of a reserves disclosure to account for relative changes in common stock prices. Multiple correlation/regression analysis was used to evaluate the extent that each of the three alternative reserves disclosures account for common stock returns after first recognizing the information provided by an industry variable and by an earnings per share or cash flow per share variable. The results indicated that the earnings per share provides significant information content while the cash flow per share consistently provides no significant evidence of information content. The capitalized costs reserves disclosure did not provide consistent evidence of information content, while the quantities disclosure and the discounted cash flows disclosure do provide significant incremental information content. The study concludes that the alternative reserves disclosures of quantities and discounted cash flows are more informative to users when accounting for changes in a corporation's common stock prices than the disclosure of reserves in historic capitalized costs.

    This Power-Point presentation described an innovative mining and extraction technology developed by Calgary-based TSC Company Ltd. that has provided a major breakthrough in bitumen production from mineable oil sands. The presentation described the process and key mechanical components as demonstrated on oil sands leases. It also described the step change in cost structure and profitability. Oil sands mining provide a hugh resource base with no exploration costs and no decline in production. Despite these advantages, oil sands mining faces the challenge of high capital and operating costs and materials handling. Other challenges include the variability of the ore and environmental impacts. This paper described the fundamentals of the new technology called the Tar Sand Combine (TSC), a continuous mining machine, crusher, cyclone, tailings filter and stacker all in one mobile module. Several viewgraphs were included with the presentation to depict the recovery process as successfully demonstrated at a pilot project. Patent is pending on the process and components. The advantages of the TSC are reduced materials handling, and no tailings ponds are generated since tailings remain where they are mined. The final product is clean bitumen. The specifications of a commercial TSC are: 2000 ton/stream hour mining produce 25,000 bpsd bitumen at 12 per cent ore grade; mined ore bitumen recovery is greater than 95 per cent and the availability factor is 85 per cent. It was concluded that the TSC can maximize oil sands reserves, while providing significant cost savings and environmental benefits. 2 tabs., 24 figs.

    The newest Slovak brown coal mine - Bana Zahorie is in crisis. Despite the fact that experts believe that along with Bana Novaky, it has the most potential. The owners have started its liquidation. One of the walls has collapsed and another part flooded. Nobody was hurt, but some equipment is still underground. The mine had already lost equipment in the past. During an accident in 2000, equipment worth several tens of millions was destroyed. 'After the accident, mining had to be stopped and from a technical point of view that was the end of the joint stock company, Bana Zahorie Cary. The company could not raise the funds necessary to recover from the accident,' stated the Director of the mine, Jan Palkovic. But he stressed that only the joint stock company is in liquidation, the mine is still being ventilated and the water is being pumped out. But the company management still does not want to specify who will become the new owner of the lignite deposits in Zahorie. The Director promised to publish more details within several weeks. All competencies and mining rights of the former Bana Zahorie are being transferred to a new company - joint stock company Bana Cary. (author)

    The average molybdenum ore throughput at the Henderson Mine near Denver, Colorado increased significantly between 2003 and 2007. In response, the Climax Molybdenum Company updated the life-of-mine plan which resulted in significant changes to the ventilation requirements of the mine. This paper outlined the mine and ventilation planning efforts. The design options that were evaluated to upgrade the ventilation system were also described along with the final design that was chosen to support the updated mine plan. The mine uses an exhaust ventilation system in which ventilation is supplied through a service shaft, an intake shaft and a long ore haulage tunnel. Currently, air is exhausted through 2 exhaust shafts. The new reserve model that was completed in 2007 incorporated updated geologic information and mix/dilution models. An evaluation of the new life-of-mine plans and production sequences drove the development of a new ventilation plan that increased the airflow requirements of the mine. The primary design concerns were radon control; reduction of diesel particulate matter; silica dust; blasting and other gases; and climate control. Ventilation requirements were also updated based on the final exposure limits stipulated in the 2008 regulations of the Mine Safety and Health Administration. 4 refs., 11 tabs., 8 figs.

    The mining industry is a vital contributor to national and global economies and yet it is very different from other industries. It is based on depleting finite mineral resources, the knowledge of which is imperfect prior to the commencement of mining or extraction. It is an industry with a colourful history of success and failure, entrepreneurs and opportunists, visionaries and short sightedness. These aspect or traits were both positive, it fostered innovation, and negative for the industry. Negative in that the merit of certain projects or results was difficult to assess, it created a credibility issue and consequently investment in the industry was impacted. In 1989 the first JORC code was released (Joint Ore Reserves Committee) in Australia. It was incorporated into the Australian Stock Exchange (ASX) listing rules thereby becoming binding on companies listed on the ASX it was also adopted by the Australian Institute of Mining and Metallurgy (AusIMM) and became binding on its members. Essentially JORC was the pre-cursor or model for an international standard for the reporting of exploration results, mineral resources and ore reserves. A trend towards tighter corporate governance and regulation demanded an international standard to “good practice” in mineral reserve management as well as high standards of public reporting by responsible, experienced persons. In 2006 CRIRSCO (Committee for Mineral Reserves International Reporting Standards)released an International Reporting Template (the Template), the purpose of which is to assist with the dissemination and promotion of effective, well-tried, good practice for public reporting of Exploration Results, Mineral Resources and Ore Reserves already widely adopted through national reporting codes and standards.

    1996-01-01

    The public reclamation cost of reclaiming all of Pennsylvania's abandoned mine lands is estimated at $15 billion. Drainage from abandoned mines poses another $5 billion water pollution clean-up problem. Although it is unlikely that public reclamation alone could ever tackle these problems, much can be done to alleviate the nuisances through the remining of previously mined areas to recover remaining reserves, restore the land and improve water quality in the same process. Remining of priority areas is encouraged through a new Pennsylvania policy which provides incentives to mining companies. One incentive, initiated under Pennsylvania's comprehensive mine reclamation strategy, is to identify and geologically map reminable coal resources in selected watersheds, and then to expedite mine permitting in these watersheds. At present, two such priority watersheds, Little Toby Creek in Elk County and Tangascootak Creek in Clinton County, are the focus of geologic map compilation based on recent quadrangle mapping, or new, directed, geologic mapping, including new research core drilling to establish the geologic stratigraphic framework. In order to maximize environmental benefits the comprehensive mine reclamation strategy identifies watersheds which are affected by acid mine drainage (AMD), but that are reasonably capable of restoration, if sufficient coal reserves remain. Pennsylvania's geochemical quality database of rock overburden, in combination with detailed coal resource mapping by the Pennsylvania Geological Survey, and the cooperation of coal companies and leaseholders, is being used by the Department of Environmental Protection (DEP) to identify and design remining projects which will not only allow the recovery of coal resources, but will also improve the water quality through a variety of innovative mining techniques

    The decline of the German mining industry and the increasing industrialization of mining is forcing ever greater numbers of young German mining graduates to build their careers abroad. The requirements for this - apart from the technical qualifications are a good knowledge of foreign languages and a readiness to leave Germany for a long time, even for ever. If the young mining graduate accepts these conditions, numerous professional opportunities will open up for him, both with German mining companies with interests abroad, in mining supply companies and consultancy firms and with foreign companies. 6 references.

  5. Ecological, economical and social impact of uranium mining activity on local communities in the area of Banat-Oravita branch of National Uranium Company

    Cocar, D.; Grigorita, L.

    2000-01-01

    In this work, the ecological, economical and social effects of uranium mining activity on environment and local communities in Caras Severin county are considered. 4412 radiochemical analyses and about 6730 radiometric measurements were made. The waters of local rivers were found to be contaminated with natural uranium and 226 radium, but the biological risk is not significant. Their concentrations and effective doses are presented in 8 tables referring to the rivers Lisava, Jitin, Caras. Also, samples of water from springs and wells in the Banat mining area were analysed for natural uranium and 226 Ra, their concentrations being found under the maximum permissible level. The air quality was not affected by accidental radon emissions. In order to limit the ecological impact on the environment, remedial action measures are proposed. The economic and social impact on the local communities are due mainly to the decline of activity, the most important effect being the unemployment

  6. Mining of high utility itemsets of size-2 with pruning strategies and negative item values for B2C companies based on experiential marketing approach

    Directory of Open Access Journals (Sweden)

    2016-09-01

    Full Text Available Business to customer (B2C marketing for the retail organisations is the most rapid adoption made by the developed countries, while it has the pitfalls in the developing nations. B2C companies have been continually putting some or the other lucrative offers and schemes on their manufactured products. There happens to be no logical demand of clubbing the sale of two products. The only need of such clubbing is the financial crisis which the company wants to overcome. Information technology can renew and make the competitive advantage for B2C companies. In this paper, a novel way for finding the itemset clubs is proposed, hence extending Apriori algorithm. The proposed methodology aims at finding the combinations of the products which can be sold together with the high levels of utility. This allows for making good profits for the company. Unlike contemporary way of items bearing positive values, negative item values have been looked into. The MHUIS-2wPS algorithm utilises the transactional experiences of the retail stores and outputs the size-2 clubs. The MHUI-NIV algorithm caters for the items with negative item values. The dissertation applies various pruning strategies for the discovery of high utility itemsets. These prunings will help remove the unnecessary formation of the low utility extensions. Later, various datasets have been used to show the essence of the algorithms.

    2006-09-01

    This study examines the total Hg contamination in soil and sediments, and the correlation between the total Hg concentration in soil and vegetables in two small scale gold mining areas, São Chico and Creporizinho, in the State of Para, Brazilian Amazon. Total Hg values for soil samples for both study areas are higher than region background values (ca. 0.15 mg/kg). At São Chico, mean values in soils samples are higher than at Creporizinho, but without significant differences at alpha1 in all of São Chico's produce samples, soil-plant parts regression were not significant, and Hg uptake probably occurs through stomata by atmospheric mercury deposition. Wild plants aboveground:root ratios were <1 at both study areas, and soil-plant parts regressions were significant in samples of Creporizinho, suggesting that they function as an excluder. The average total contents of Hg in edible parts of produces were close to FAO/WHO/JECFA PTWI values in São Chico area, and much lower in Creporizinho. However, Hg inorganic small gastrointestinal absorption reduces its adverse health effects.

    In mining areas belonging to the Polish mining companies, there is a significant amount of coal, contained in remaining reserves, that have not been exploited so far. For years, the mines have been evaluating the possibility of its exploitation, since it would expand its resource base and would extend its useful life. In addition, exploitation of the remaining reserves can minimize stress concentration zones in the soil, the rebel y improving conditions for maintenance of excavations and limiting the risk of shock rock.

    The object of this study consists of an open mine from which Niobium ore (pyrochlore) is extracted and a metallurgy company, where Fe-Nb alloys are produced for export. For geological reasons, the main ore is associated to natural radionuclides U and Th, and its decay products. The concentration of 234 U, 238 U, 232 Th, 226 Ra and 228 Ra, 228 Th, including 210 Pb in fecal excretion of 12:0 am, 29 workers and 13 family members were determined. The technique employed for the determination of the elements was the sequential method of radiochemical separation, followed by alpha spectrometry and counting α and β in proportional detector. Statistically significant difference was observed in the concentration of 234 U and 238 U, in feces samples, among the group of mining workers and family members; as well as for 232 Th in the feces of workers of crushing and metallurgy groups when compared with the Family Group. No statistically significant difference was detected at a concentration of 226 Ra, 228 Ra and 210 Pb, in feces of any group of workers of the installation in relation to the family group

  13. Data mining, mining data : energy consumption modelling

    Energy Technology Data Exchange (ETDEWEB)

    Dessureault, S. [Arizona Univ., Tucson, AZ (United States)

    2007-09-15

    Most modern mining operations are accumulating large amounts of data on production and business processes. Data, however, provides value only if it can be translated into information that appropriate users can utilize. This paper emphasized that a new technological focus should emerge, notably how to concentrate data into information; analyze information sufficiently to become knowledge; and, act on that knowledge. Researchers at the Mining Information Systems and Operations Management (MISOM) laboratory at the University of Arizona have created a method to transform data into action. The data-to-action approach was exercised in the development of an energy consumption model (ECM), in partnership with a major US-based copper mining company, 2 software companies, and the MISOM laboratory. The approach begins by integrating several key data sources using data warehousing techniques, and increasing the existing level of integration and data cleaning. An online analytical processing (OLAP) cube was also created to investigate the data and identify a subset of several million records. Data mining algorithms were applied using the information that was isolated by the OLAP cube. The data mining results showed that traditional cost drivers of energy consumption are poor predictors. A comparison was made between traditional methods of predicting energy consumption and the prediction formed using data mining. Traditionally, in the mines for which data were available, monthly averages of tons and distance are used to predict diesel fuel consumption. However, this article showed that new information technology can be used to incorporate many more variables into the budgeting process, resulting in more accurate predictions. The ECM helped mine planners improve the prediction of energy use through more data integration, measure development, and workflow analysis. 5 refs., 11 figs.

    1994-01-01

    The Midnite Mine is an inactive, hardrock uranium mine on the Spokane Indian Reservation, Stevens County, WA. Oxidation of sulfide-containing minerals, primarily pyrite, in the ore body produces large quantities of acidic water. An interception system installed by the mining company limits the discharge of contaminated water from the mine. The Bureau of Indian Affairs and the Bureau of Land Management have been actively involved in planning remediation of the disturbed areas. To assist in remediation, the U.S. Bureau of Mines initiated research to determine water quality and define groundwater flow characteristics. Bureau personnel designed a monitoring network, supervised installation of sampling wells, and collected and analyzed water samples. This Report of Investigations describes interpretation of data collected between December 1989 to April 1992

  16. Modeling land use and cover change: Predicting re-enrollment in the Conservation Reserve Program using GIS and data mining procedures

    Science.gov (United States)

    Shcherbaniuk, Mykola Vasylyovych

    In this research, the concept of the CRP lands being re-enrolled or returned to crop production was considered as a part of a larger conceptual domain of land use and cover change (LUCC). The aim of the study was to develop models for predicting the probability of farmers' re-enrollment in the Conservation Reserve Program (CRP) in the Cache River Watershed, in Southern Illinois. The results of these analyses showed that the probability of the CRP re-enrollment is a function of a number of factors including both the economic incentives to farmers as well as the spatial and non-spatial characteristics of the farms and the CRP land parcels. Both logistical regressions and decision tree models confirmed the importance of seven individual variables. It was found that the probability of CRP re-enrollment was higher for parcels located closer to a stream, the national forest, a road and a town. Also higher re-enrollment was indicated for predominant farm location adjacent to the national forest and within a floodplain and on dry soils, higher proportion of farmland in pasture and higher elevation and population density. Alternatively, the probability of re-enrollment was found to be lower closer to an interstate highway, predominant farm location adjacent to the national refuge and higher proportion of farmland in row crops. The probability of CRP re-enrollment was found to be higher at higher CRP rental rates, lower commodity prices, lower cropland acreage, and lower proportion of farmland in cropland. For two additional important determinants, the probability of re-enrollment was found to be higher for lower proportion of cropland enrolled in CRP and in cases where the farmer was both the owner and operator. Overall, the results of this study indicate that the spatial heterogeneity of farms and land parcels (as accounted by spatial variables that were found to be relevant) should be taken into account while malting the plans for the CRP re-enrollment for the 2007 farm

  17. The Necessity of Public Relations for Sustainable Mining Activities

    2015-04-01

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

    Spatial planning is supposed to be applied in the use of space, so there will be no overlapping space utilization. In fact, there are still overlapping uses of land, between the area of mining and plantation, as well as with forest areas. The purpose of this study was to find out the conflicts that occured due to overlapping permits given to mining and plantation companies, and also to forest status. The method used was by overlaying the maps of Mining Business Permit with that of Plantation Business Permit, and also with Forest Area Map. In Tolitoli District there were 23 mining business permit holders with 7 types of mining commodities, covering total areaof 81,503.54 Hectare. In addition, there were 5 companies holding plantation business permits, mostly on palm oil, and only 2 companies with rubber and sengon wood business commodities, with a total area of 80,005.35 Hectare. From the result of spatial analysis, it was found that there was an overlapping area of 22,869.70 Hectare, while the area of 118,072.93 Hectare did not overlap. The Mining Business Permit overlapped with the Plantation Business Permit covering an area of 18,853.32 Hectare, and 4,301.77 Hectare were located in Forest Protected Area and Nature Reserve.

  20. Reserves reporting for decision-making planning and control

    International Nuclear Information System (INIS)

    Higgins, G.

    1992-01-01

    This paper shows how the established Monte Carlo simulation approach to estimating hydrocarbon reserves can be expanded to provide the basis of a comprehensive valuation, planning and control system meeting all the reserve reporting requirements of an oil exploration and production company. The approach presented is also appropriate for other mining and extractive industries. The paper demonstrates how individual expectation curves can be modified to reflect both technically and commercially recoverable reserves and how these are in turn combined into the economic valuation, planning and control processes of an enterprise. Estimates across the full range of risk and reserves can be aggregated to provide a powerful planning tool that can be used to set corporate, divisional and individual objectives

    The difficult economic circumstances with which almost the whole world had to contend, brought serious financial crisis in many countries. South Africa also had its own share of serious problems. Despite this situation, Transvaal Consolidated Land and Exploration Company, Limited, showed on increase in earnings of 24 per cent per share. The reason for this lies mainly in two areas. Firstly the company acquired the mining related business of Rand Mines, Limited. Included in the acquisition was a partfolio of shares mainly in the company's associated gold and uranium mining companies and additional shares in its listed coal mining subsidiaries. Secondly, the average gold price realised by producers in rand terms, was considerably higher than in the previous year. Consolidated profit attributable to members increased by 52 per cent to R82,6 million

    2014-07-01

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

    Mining plays a vital role in the economic development of many countries. The emerging economies are now major players in the production and availability of key commodities such as copper (70%), bauxite (40%), iron ore and precious metals. Mining also has a positive impact on the economy of many countries. Another impact of mining can be measured in terms of employment opportunities and income generation. Commercial scale mining provides employment and skills transfer to more than 2 million workers. The multiplier effect increases this benefit by a factor of between 2 and 5. The World Bank Mining Department has carried out an in-depth study on economic and social impact of mining at the community level in Chile, Peru, Bolivia, Papua New Guinea and Mali. This study demonstrates that there are substantial social and economic benefits to the community. The most positive cases are related to the growth of local small- and micro-enterprise activities. However, mining remains controversial, as true sustainable development is not only a matter of financial flows. Mining has also been associated with a number of economic and social problems. As a result there are questions about the sustainability of the economic outcome of mining. The contribution of mining to sustainable development needs to be considered in terms of economic and technical viability, ecological sustainability and social equity. To achieve this, governments, mining companies and local communities must work together to address these issues. (author)

    Full Text Available Tests for bioaccessibility are useful in human health risk assessment. No research data with the objective of determining bioaccessible arsenic (As in areas affected by gold mining and smelting activities have been published so far in Brazil. Samples were collected from four areas: a private natural land reserve of Cerrado; mine tailings; overburden; and refuse from gold smelting of a mining company in Paracatu, Minas Gerais. The total, bioaccessible and Mehlich-1-extractable As levels were determined. Based on the reproducibility and the accuracy/precision of the in vitro gastrointestinal (IVG determination method of bioaccessible As in the reference material NIST 2710, it was concluded that this procedure is adequate to determine bioaccessible As in soil and tailing samples from gold mining areas in Brazil. All samples from the studied mining area contained low percentages of bioaccessible As.

  15. Mega-mining in Mexico. Structural reforms and resistance

    Directory of Open Access Journals (Sweden)

    Darcy Tetreault

    2013-11-01

    Full Text Available This article analyzes the structural causes of social environmental conflicts around mega-mining in Mexico and describes the emergence and coordination of resistance movements. It argues that neoliberal reforms have facilitated ‘accumulation by dispossession’ on two levels: first, by transferring public resources in the form of mineral reserves and state-run mining companies to the private sector; and second, bydispossessing smallholder farmers and indigenous communities of their land, water and cultural landscapes, in order to allow mining companies to carry out their activities. Furthermore, it argues that some factions of the resistance movements reflect ‘the environmentalism of the poor’ insofar as they seek to maintain natural resources outside of the sphere of the capitalist mode of production. Through a systematic revision of newspaper articles, blogs and scholarly publications, 29 high-profile eco-territorial mining conflicts are identified and a preliminary analysis of these is provided.

  16. Sustainable mining management

    Mining activities are carried out by the older man and have provided resources, since ancient times, for their development and progress. With the discovery of fire will show the first metals that have marked the civilizations of copper, bronze and iron, and is the prehistory of the Stone Age tools that man has made from the exploitation of quarries first. The industrial revolution of the nineteenth century is linked to coal and steel, and could not conceiver of todays society without oil and gas, without silicon and coltan. But the mines are often aggressive and, despite their need and what they contribute to the development are answered by the societies where are made. during recent years there has been growing international efforts to try to make the minimum requirements of sustainable exploitation (European Directives, GMI, GRI, etc.) In AENOR, and within the Technical Committee of Standardization 22 Mining and Explosives, chaired by AITEMIN, was established the subcommittee 3, chaired by IGME, where, with the participation of all stake holders, have developed some standards on sustainable mining management sustainable mining that will be a tool available to mining companies to demonstrate their sustainable use to Society.

    2016-01-01

    Full Text Available Throughout this paper those technical and accounting concepts of the Law of mining privileges that generate ambiguity and incongruity for businesses has been analyzed and identified. For this reason, we have developed a proposal amending the calculation of mining privileges based on two main aspects: (i terminology used in the law and (ii establishment of income before retribution to stakholders and taxes as a basis for calculating privileges. As a result, it was established as an object of study for all mining companies paying privileges; however, for purposes of the investigation three representative mining companies of medium and large mining were selected. Later interviews were arranged with financial and tax managers of the companies mentioned above as well as experts in the field of mining privileges; it was concluded that the concepts of "cost" and "corresponding fiscal year" mentioned in the Law generated ambiguities, inconsistencies and accounting distortions. Also, mining companies and experts agreed that the current basis for the calculation of the privileges is not adequate for the mining sector since it does not reflect the financial situation of companies. Therefore, a proposal for reformulation of the applied priviously and a new basis for calculating the mining privileges based on the cost of sales is made; since, in the cost of sales is found what Kieso and Weygandt (1999 denominated as "the price paid for the right to seek and find a hidden Natural resources, or paid by a source already discovered"

  20. Mine drivage in hydraulic mines

    Energy Technology Data Exchange (ETDEWEB)

    Ehkber, B Ya

    1983-09-01

    From 20 to 25% of labor cost in hydraulic coal mines falls on mine drivage. Range of mine drivage is high due to the large number of shortwalls mined by hydraulic monitors. Reducing mining cost in hydraulic mines depends on lowering drivage cost by use of new drivage systems or by increasing efficiency of drivage systems used at present. The following drivage methods used in hydraulic mines are compared: heading machines with hydraulic haulage of cut rocks and coal, hydraulic monitors with hydraulic haulage, drilling and blasting with hydraulic haulage of blasted rocks. Mining and geologic conditions which influence selection of the optimum mine drivage system are analyzed. Standardized cross sections of mine roadways driven by the 3 methods are shown in schemes. Support systems used in mine roadways are compared: timber supports, roof bolts, roof bolts with steel elements, and roadways driven in rocks without a support system. Heading machines (K-56MG, GPKG, 4PU, PK-3M) and hydraulic monitors (GMDTs-3M, 12GD-2) used for mine drivage are described. Data on mine drivage in hydraulic coal mines in the Kuzbass are discussed. From 40 to 46% of roadways are driven by heading machines with hydraulic haulage and from 12 to 15% by hydraulic monitors with hydraulic haulage.

  1. Uranium - a challenging mining business

    International Nuclear Information System (INIS)

    Stadelhofer, J.W.; Wedig, M.J.

    2007-01-01

    The main application of uranium is its use as a fuel for the nuclear electricity generation. Presently about 68,000 t (177 mill. lbs) of uranium are annually required, of which 41,500 (108 mill. lbs) are provided from fresh mine production whereas 26,500 t (69 mill. lbs) are stock drawdown supplies from civil or military sources. Two-thirds of production are recovered by underground mining and about 75% (30,350 t) of the world's uranium mine production are extracted from top ten mines. All major uranium mining companies are making efforts to enlarge their production capacities: The paramount Cameco's Cigar Lake project has been delayed due to mine water inflow. Production is expected to commence by latest in 2010; the nameplate capacity of 6000 t/a should be reached in 2011. AREVA reported plans to invest about Euro 500 to 600 mill. to double its uranium production by 2010. In 2006 Denison Mines and International Uranium Corporation announced that they have entered into an agreement to merge the two companies in order to create a mid-tier, North American-focused uranium producer with the potential annual production of more than 5.5 mill. lbs of U 3 O 8 by 2010. The skyrocketing global electricity demand, growing public acceptance and more favourable policies have initiated a new round of global development of the nuclear industry. Against this backdrop, about 30,000 t/a to 40,000 t/a of additional mine production will be required within the upcoming 20 years to substitute secondary uranium supplies and to meet the expected increased demand; new start-up junior mining companies (e.g. Paladin) will contribute to this increased production.

    Davies, W.

    1997-01-01

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

    2011-11-01

    Full Text Available In 1996, a Canadian company started geological explorations in the Rosia Montana area in the Romanian Carpathians. Two years later it formed a joint-venture with a Romanian state company to exploit what is believed to be Europe´s largest gold reserves. However, as of June 2011 extraction has not started yet and it may never start due to the opposition of numerous NGO´s that have pointed out the environmental, social and economic unsustainability of this mining project. This situation is highly unusual for a country that is hungry for foreign investment especially since up until very recently the state had supported any project promising to revitalize its mining sector. This paper will investigate the changes in the discourses surrounding this mining project taking into consideration the effects of globalization and the effects of Romania´s EU membership after 2007.

  9. New approach for reduction of diesel consumption by comparing different mining haulage configurations.

    Science.gov (United States)

    Rodovalho, Edmo da Cunha; Lima, Hernani Mota; de Tomi, Giorgio

    2016-05-01

    The mining operations of loading and haulage have an energy source that is highly dependent on fossil fuels. In mining companies that select trucks for haulage, this input is the main component of mining costs. How can the impact of the operational aspects on the diesel consumption of haulage operations in surface mines be assessed? There are many studies relating the consumption of fuel trucks to several variables, but a methodology that prioritizes higher-impact variables under each specific condition is not available. Generic models may not apply to all operational settings presented in the mining industry. This study aims to create a method of analysis, identification, and prioritization of variables related to fuel consumption of haul trucks in open pit mines. For this purpose, statistical analysis techniques and mathematical modelling tools using multiple linear regressions will be applied. The model is shown to be suitable because the results generate a good description of the fuel consumption behaviour. In the practical application of the method, the reduction of diesel consumption reached 10%. The implementation requires no large-scale investments or very long deadlines and can be applied to mining haulage operations in other settings. Copyright © 2016 Elsevier Ltd. All rights reserved.

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.)

  12. Geochemical characterization of acid mine lakes in northwest Turkey and their effect on the environment.

    Science.gov (United States)

    Yucel, Deniz Sanliyuksel; Baba, Alper

    2013-04-01

    Mining activity generates a large quantity of mine waste. The potential hazard of mine waste depends on the host mineral. The tendency of mine waste to produce acid mine drainage (AMD) containing potentially toxic metals depends on the amounts of sulfide, carbonate minerals, and trace-element concentrations found in ore deposits. The acid mine process is one of the most significant environmental challenges and a major source of water pollution worldwide. AMD and its effects were studied in northwest Turkey where there are several sedimentary and hydrothermal mineral deposits that have been economically extracted. The study area is located in Can county of Canakkale province. Canakkale contains marine, lagoon, and lake sediments precipitated with volcanoclastics that occurred as a result of volcanism, which was active during various periods from the Upper Eocene to Plio-Quaternary. Can county is rich in coal with a total lignite reserve >100 million tons and contains numerous mines that were operated by private companies and later abandoned without any remediation. As a result, human intervention in the natural structure and topography has resulted in large open pits and deterioration in these areas. Abandoned open pit mines typically fill with water from runoff and groundwater discharge, producing artificial lakes. Acid drainage waters from these mines have resulted in the degradation of surface-water quality around Can County. The average pH and electrical conductivity of acid mine lakes (AMLs) in this study were found to be 3.03 and 3831.33 μS cm(-1), respectively. Total iron (Fe) and aluminum (Al) levels were also found to be high (329.77 and 360.67 mg L(-1), respectively). The results show that the concentration of most elements, such as Fe and Al in particular, exceed national and international water-quality standards.

    Full Text Available Coal and gas outbursts are one of risk factors accompanying the mining of coal in low seams in the Ostrava-Karviná Coalfield.At the use of the method of longwall mining, all coal reserves have not been mined out owing to tectonic faults. For mining outthe residual reserves, the application of a new mining method - drilling of a coal pillar was proposed.The method of mining of a coal seam utilizing long large diameter boreholes is verified in the Paskov Mine (company OKD, JSC –Czech Republic under conditions of rock mass with hazard of rock and gas outbursts in localities of residual pillars left in seams afterfinishing the mining operations performed with using the classical method of longwall working along the strike. [5]Forecast and preventive measures applied to the verification of the new method were based on previous experience withthe mining of seams with hazard of coal and gas outbursts. They accepted fully valid legislation, i.e. Ordinance of Ostrava RegionalMining Authority No. 3895/2002 and supplementary materials (Instructions and Guidelines. The proposed measures respectedthe character of the method being verified. [4]For all areas being mined, projects containing also chapters specifying the problems of ensuring the safety of mining worksand operation under conditions of hazard of coal and gas outbursts were prepared.In the contributions, basic proposals for the principles of coal and gas outburst forecast and prevention when applying the newmining method – drilling of a coal pillar are presented

  17. Lithium reserves and resources

    Evans, R.K.

    1978-01-01

    As a result of accelerating research efforts in the fields of secondary batteries and thermonuclear power generation, concern has been expressed in certain quarters regarding the availability, in sufficient quantities, of lithium. As part of a recent study by the National Research Council on behalf of the Energy Research and Development Administration, a subpanel was formed to consider the outlook for lithium. Principal areas of concern were reserves, resources and the 'surplus' available for energy applications after allowing for the growth in current lithium applications. Reserves and resources were categorized into four classes ranging from fully proved reserves to resources which are probably dependent upon the marketing of co-products to become economically attractive. Because of the proprietary nature of data on beneficiation and processing recoveries, the tonnages of available lithium are expressed in terms of plant feed. However, highly conservative assumptions have been made concerning mining recoveries and these go a considerable way to accounting for total losses. Western World reserves and resources of all classes are estimated at 10.6 million tonnes Li of which 3.5 million tonnes Li are located in the United States. Current United States capacity, virtually equivalent to Western World capacity, is 4700 tonnes Li and production in 1976 approximated to 3500 tonnes Li. Production for current applications is expected to grow to approx. 10,000 tonnes in year 2000 and 13,000 tonnes a decade later. The massive excess of reserves and resources over that necessary to support conventional requirements has limited the amount of justifiable exploration expenditures; on the last occasion, there was a a major increase in demand (by the USAEA) reserves and capacity were increased rapidly. There are no foreseeable reasons why this shouldn't happen again when the need is clear. (author)

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

    Directory of Open Access Journals (Sweden)

    Alvin A. Camba

    2016-06-01

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

  8. Appraisal of Hydrologic Information Needed in Anticipation of Lignite Mining in Lauderdale County, Tennessee

    Science.gov (United States)

    Parks, William Scott

    1981-01-01

    Lignite in western Tennessee occurs as lenses or beds at various stratigraphic horizons in the Coastal Plain sediments of Late Cretaceous and Tertiary age. The occurrence of this lignite has been known for many decades, but not until the energy crisis was it considered an important energy resource. In recent years, several energy companies have conducted extensive exploration programs in western Tennessee, and tremendous reserves of lignite have been found. From available information, Lauderdale County was selected as one of the counties where strip-mining of lignite will most likely occur. Lignite in this county occurs in the Jackson and Cockfield Formations, undivided, of Tertiary age. The hydrology of the county is known only from regional studies and the collection of some site-specific data. Therefore, in anticipation of the future mining of lignite, a plan is needed for obtaining hydrologic and geologic information to adequately define the hydrologic system before mining begins and to monitor the effects of strip-mining once it is begun. For this planning effort, available hydrologic, geologic, land use, and associated data were located and compiled; a summary description of the surface and shallow subsurface hydrologic system was prepared: the need for additional baseline hydrologic information was outlined; and plans to monitor the effects of strip-mining were proposed. This planning approach, although limited to a county area, has transferability to other Coastal Plain areas under consideration for strip-mining of lignite.

    2010-01-01

    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.

    2016-04-01

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

    Grancea, Luminita

    2015-01-01

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

    The decay of demand, the bad financial results of the first half of 2009 and the hypothetical depletion of reserves must not hide a reality: oil companies are passing through the economic crisis without much trouble. Even if profits have marked time in volume (-57% for BP, -65% for Shell..), the net margins have not significantly suffered and the available cash remains comfortable (14 billion euros for Total as an example). The perspectives offered by the new offshore sites (like Santos in Brazil) added to the fabulous promises of the Iraqi market where 'majors' can now make their come-back will be the key of success of oil companies. The overall exploration-production investments should start up again by the beginning of 2011. For the only offshore drilling domain, they should rise up by 32% during the 2009-2013 period which represents a sum of 367 billion dollars. (J.S.)

  5. Coal mine subsidence

    International Nuclear Information System (INIS)

    Darmody, R.G.; Hetzler, R.T.; Simmons, F.W.

    1992-01-01

    Longwall coal mining in southern Illinois occurs beneath some of the best agricultural land in the U.S. This region is characterized by highly productive, nearly level, and somewhat poorly drained soils. Subsidence from longwall mining causes changes in surface topography which alters surface and subsurface hydrology. These changes can adversely affect agricultural land by creating wet or ponded areas that can be deleterious to crop production. While most subsided areas show little impact from subsidence, some areas experience total crop failure. Coal companies are required by law to mitigate subsidence damage to cropland. The objective of this paper is to test the effectiveness of mitigation in restoring grain yields to their pre-mined levels. The research was conducted on sites selected to represent conventional mitigation techniques on the predominate soils in the area. Corn (Zea mays L.) and soybean [Glycine max.(L.) Merr] yields in 1988, 1989, 1990, and 1991 from mitigated areas were compared to yields from nearby undisturbed areas

  6. Mines in the Four Corners anticipate growth

    Energy Technology Data Exchange (ETDEWEB)

    Buchsbaum, L.

    2008-02-15

    Productive mines in the southwest deplete reserves, while the government drags its heels on new power projects. Production in Arizona and New Mexico has fallen 18% over the last four years to 34.1 million tons. With Chevron Mining's McKinley mine rapidly depleting its reserves the industry will continue to contract. In the last three years at least three large mines in the Four Corners have terminated operations. Three others remain captive operations: BHP Billiton's San Juan Underground and Navajo Surface operations and Peabody Energy's Kayenta surface mine. In 2006 the Black Mesa mine stopped producing coal. These four mines are isolated from the national railways. Peabody's new El Segundo surface mine near Grants, NM is increasing production. If the planned $3 billion Desert Rock coal-fired power plant is built this will present a new market for the Navajo mine. The article gives details about the state of the aforementioned mines and of the new King II coal mine on the northern periphery of the San Juan basin and discusses the state of plans for the Desert Rock Energy Project. 5 photos.

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

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

    This paper reports on state owned oil and gas companies which dominate the OGJ100 list of major non U.S. holders of petroleum reserves. Many state companies report only production and reserves information and do not report financial data. Therefore, the companies cannot be ranked by financial data, as they are in the OGJ300. They instead are listed by region, based on location of companies' corporate headquarters. The top 20 companies in crude oil production and reserves are shown. The leading nongovernment company in both reserves and production is Royal Dutch/Shell Group - No. 11 in worldwide liquids reserves and No. 6 in liquids production. Crude oil reserves of the top 20 companies moved up less than 1% last year, increasing 401.5 billion bbl. The year before, when there were substantial reserves adjustments, the top 20 posted an increase of 139.3 billion bbl

    Process mining includes the automated discovery of processes from event logs. Based on observed events (e.g., activities being executed or messages being exchanged) a process model is constructed. One of the essential problems in process mining is that one cannot assume to have seen all possible...... behavior. At best, one has seen a representative subset. Therefore, classical synthesis techniques are not suitable as they aim at finding a model that is able to exactly reproduce the log. Existing process mining techniques try to avoid such “overfitting” by generalizing the model to allow for more...... support for it). None of the existing techniques enables the user to control the balance between “overfitting” and “underfitting”. To address this, we propose a two-step approach.

    The oxidative dissolution of sulfidic minerals releases the extremely acidic leachate, sulfate and potentially toxic elements e.g., As, Ag, Cd, Cr, Cu, Hg, Ni, Pb, Sb, Th, U, Zn, etc. from different mine tailings and waste dumps. For the sustainable rehabilitation and disposal of mining waste, the sources and mechanisms of contaminant generation, fate and transport of contaminants should be clearly understood. Therefore, this study has provided a critical review on (1) recent insights in mechanisms of oxidation of sulfidic minerals, (2) environmental contamination by mining waste, and (3) remediation and rehabilitation techniques, and (4) then developed the GEMTEC conceptual model/guide [(bio)-geochemistry-mine type-mineralogy- geological texture-ore extraction process-climatic knowledge)] to provide the new scientific approach and knowledge for remediation of mining wastes and acid mine drainage. This study has suggested the pre-mining geological, geochemical, mineralogical and microtextural characterization of different mineral deposits, and post-mining studies of ore extraction processes, physical, geochemical, mineralogical and microbial reactions, natural attenuation and effect of climate change for sustainable rehabilitation of mining waste. All components of this model should be considered for effective and integrated management of mining waste and acid mine drainage. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The reducing coal market has been enforcing the coal industry to make exceptional rationalization and restructuring efforts since the end of the eighties. To the competition from crude oil and natural gas has been added the growing pressure from rising wages and rising production cost as the workings get deeper. To improve the competitive position of the coal mines against oil and gas through cost reduction, studies to improve mining system have been carried out. To find fields requiring improvements most, the technologies using in Tae Bak Colliery which was selected one of long running mines were investigated and analyzed. The mining method appeared the field needing improvements most to reduce the production cost. The present method, so-called inseam roadway caving method presently is using to extract the steep and thick seam. However, this method has several drawbacks. To solve the problems, two mining methods are suggested for a long term and short term method respectively. Inseam roadway caving method with long-hole blasting method is a variety of the present inseam roadway caving method modified by replacing timber sets with steel arch sets and the shovel loaders with chain conveyors. And long hole blasting is introduced to promote caving. And pillar caving method with chock supports method uses chock supports setting in the cross-cut from the hanging wall to the footwall. Two single chain conveyors are needed. One is installed in front of chock supports to clear coal from the cutting face. The other is installed behind the supports to transport caved coal from behind. This method is superior to the previous one in terms of safety from water-inrushes, production rate and productivity. The only drawback is that it needs more investment. (author). 14 tabs., 34 figs.

    Background Every year, many mining accidents occur in underground mines all over the world resulting in the death and maiming of many miners and heavy financial losses to mining companies. Underground mining accounts for an increasing share of these events due to their special circumstances and the risks of working therein. Thus, the optimal location of emergency stations within the network of an underground mine in order to provide medical first aid and transport injured people at the right time, plays an essential role in reducing deaths and disabilities caused by accidents Objective The main objective of this study is to determine the location of emergency stations (ES) within the network of an underground coal mine in order to minimize the outreach time for the injured. Methods A three-objective mathematical model is presented for placement of ES facility location selection and allocation of facilities to the injured in various stopes. Results Taking into account the radius of influence for each ES, the proposed model is capable to reduce the maximum time for provision of emergency services in the event of accident for each stope. In addition, the coverage or lack of coverage of each stope by any of the emergency facility is determined by means of Floyd-Warshall algorithm and graph. To solve the problem, a global criterion method using GAMS software is used to evaluate the accuracy and efficiency of the model. Conclusions 7 locations were selected from among 46 candidates for the establishment of emergency facilities in Tabas underground coal mine. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  10. Trust and safety in the coal mining sector

    Neil Gunningham; Darren Sinclair [Gunningham and Associates (Australia)

    2008-08-15

    This report examines the relationship between trust (and mistrust) and occupational health and safety (OHS) in the Australian coal mining sector. Previous research in Australian coal mining companies indicated that mistrust is deep-seated at a number of mines, and that these mines are usually the worst performers in terms of OHS. Mistrust also handicaps the ability of inspectors to worker together with mines sites to improve OHS outcomes. Given this, there is a compelling need to understand how mistrust comes about, and to identify practical steps that can be adopted by companies, mines sites and the inspectorate to foster the development of trust. The report builds on these earlier findings by investigating trust in a much more detailed and sophisticated fashion, drawing on an in-depth analysis at mines, across a number of coal mining companies, and in two state jurisdictions. Research revealed that a 'cluster of characteristics' are associated with the formation and maintenance of mistrust at mines with a lower OHS track-record. These findings, together with an analysis of the characteristics of mines with better OHS outcomes, enabled the report to outline a variety of ways in which mines may build trust within and between management and the workforce. It also considers the at times fractious relationship between trade unions and management, and flags some of the challenges confronting these two groups in working together to improve OHS performance in the coal mining sector. Finally, the report examines the rise and impact of mistrust on the operations of the New South Wales and Queensland inspectorates, and suggests ways in which a fairer and more just enforcement policy may help foster greater trust between inspectors and mines.

  11. Data mining goes multidimensional.

    The success of a healthcare organization depends on its ability to acquire, store, analyze and compare data across many parts of the enterprise, by many individuals. While relational databases have been around since the 1970s, their two-dimensional structure has limited--or made impossible--the kind of cross-dimensional trend analysis so necessary to healthcare today. Enter online analytical processing (OLAP), in which servers store data in multiple dimensions, opening a world of opportunity for data-mining across the enterprise. In this issue of HEALTHCARE INFORMATICS, we feature our first report from the National Software Testing Laboratories (NSTL) about technologies that will change the way healthcare does business. A division of The McGraw-Hill Companies, NSTL is an independent software and hardware testing lab offering services that include compatibility testing, bug testing, comparison testing, documentation evaluation and usability.

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

    IFP and the OAPEC jointly organize a regular international seminar dealing with world oil-related problems appearing in the news. For the first time, this seminar has been opened to oil and gas company specialists, service companies, research centers and independents. This year's theme concerns oil and gas reserves: are they abundant or are we headed towards the shortages announced by some experts? This theme is especially topical in that: oil and gas currently meet two thirds of world energy needs and almost completely dominate the transport sector; the reserves declared by the OAPEC countries account for nearly half of world reserves; the price of a barrel of oil went through the roof in 2004; world energy demand is growing fast and alternative sources of energy are far from ready to take over from oil and gas in the next few decades. Since the reserves correspond to the volume it is technically and economically viable to produce, the seminar has, of course, dealt with the technical and economic questions that arise in connection with exploration and production, but it has also considered changes in the geopolitical context. Presentations by the leading companies of the OAPEC countries and by the IFP group were completed by presentation from the International Energy Agency (IEA), the United States Geological Survey (USGS), the IHS Energy Group, Total and Gaz de France. This document gathers the transparencies of the following presentations: Hydrocarbon reserves in OAPEC members countries: current and future (M.

    The Ruhr is a German region undergoing a reconversion. In recent years, several thousand jobs have been lost in the coal, iron and steel industries, especially in coal mines. This trend is going to continue. Rehabilitating former industrial sites so that they can welcome new industries and businesses, is decisive for this region. A rapid and financially advantageous reconversion requires coherence and continuity in the rehabilitation measures undertaken by the companies that serve as receivers, by local authorities and by investors who want to launch new projects. All these parties must manage the various phases of this process in a spirit of coordination. Germany can boast of a series of successful reconversions into industrial areas, exhibition facilities, nature reserves, tourist centers and leisure and rest places

  12. Economics of mining law

    Science.gov (United States)

    Long, K.R.

    1995-01-01

    Modern mining law, by facilitating socially and environmentally acceptable exploration, development, and production of mineral materials, helps secure the benefits of mineral production while minimizing environmental harm and accounting for increasing land-use competition. Mining investments are sunk costs, irreversibly tied to a particular mineral site, and require many years to recoup. Providing security of tenure is the most critical element of a practical mining law. Governments owning mineral rights have a conflict of interest between their roles as a profit-maximizing landowner and as a guardian of public welfare. As a monopoly supplier, governments have considerable power to manipulate mineral-rights markets. To avoid monopoly rent-seeking by governments, a competitive market for government-owned mineral rights must be created by artifice. What mining firms will pay for mineral rights depends on expected exploration success and extraction costs. Landowners and mining firms will negotlate respective shares of anticipated differential rents, usually allowing for some form of risk sharing. Private landowners do not normally account for external benefits or costs of minerals use. Government ownership of mineral rights allows for direct accounting of social prices for mineral-bearing lands and external costs. An equitable and efficient method is to charge an appropriate reservation price for surface land use, net of the value of land after reclamation, and to recover all or part of differential rents through a flat income or resource-rent tax. The traditional royalty on gross value of production, essentially a regressive income tax, cannot recover as much rent as a flat income tax, causes arbitrary mineral-reserve sterilization, and creates a bias toward development on the extensive margin where marginal environmental costs are higher. Mitigating environmental costs and resolving land-use conflicts require local evaluation and planning. National oversight ensures

    Full Text Available Mineral resources are finite and nonrenewable in the sense that their extraction permanently depletes a country's resource inventory. The role of governments should be to manage the exploitation of these resources to maximize the economic benefits to their community, consistent with the need to attract and retain the exploration and development capital necessary to continue to realize these benefits for as long as possible. In designing mineral sector taxation systems, policy makers must carefully seek to balance tax types, rates, and incentives that satisfy the needs of both the nation and the mining investor.

  7. Trekkopje Mine. Stakeholder Report 2012-2013

    International Nuclear Information System (INIS)

    2014-01-01

    This document is Areva Namibia's stakeholder report for 2012-2013. During this time the company successfully completed pilot testing at the MIDI site, produced 440 tons of uranium and gained valuable experience that will help it optimise the process in the MAXI phase. The uranium was exported for further processing into nuclear fuel at the converter facility in France and royalties were paid to the Namibian government. The last two years were challenging for the uranium industry. There is currently an over-supply of uranium on the world market, partly due to Japan's nuclear reactors being stopped, and the spot market price dropping below US$40 per pound of uranium oxide in mid-2013. This has severely affected new developments in Namibia which generally need higher prices of around US$60-80 per pound to be viable. Taking into account the current economic conditions and the substantial investments yet to be made at the Trekkopje MAXI plant, it was decided to put the project on hold. The Trekkopje project went into a 'Care and Maintenance' phase from 1 July 2013. The mine is merely in a holding phase with every intention to start up as soon as the economic conditions become more favourable. The company is actively supporting local economic development through the Erongo Development Foundation's SME micro-finance scheme. On 14 August 2013, Areva signed an initial water supply agreement with NamWater. This agreement is a prelude to a medium-term contract to distribute up to 10 million cubic meters per annum. Areva's Erongo Desalination Plant will contribute to water supply security and help preserve the water reserves of the Erongo region.

    Directory of Open Access Journals (Sweden)

    SUCIU GHEORGHE

    2014-05-01

    Full Text Available Companies, especially nowadays, are characterized through great mobility, fast circulation of capital, occurring in their chase for profit. In this context, companies look for alliances, economical and political assistance. These objectives can materialize through merging of companies. The merger can be internal (between Romanian companies or transboundary, which includes foreign companies. In order to correctly reflect these events, the merger operations must be regulated and must respect national and international regulations. One important request concerning the merger operations is that the accounting values of the assets, debts and ownership equity must be brought to the present financial value.

  9. Uranium mining

    International Nuclear Information System (INIS)

    Cheeseman, E.W.

    1980-01-01

    The international uranium market appears to be currently over-supplied with a resultant softening in prices. Buyers on the international market are unhappy about some of the restrictions placed on sales by the government, and Canadian sales may suffer as a result. About 64 percent of Canada's shipments come from five operating Ontario mines, with the balance from Saskatchewan. Several other properties will be producing within the next few years. In spite of the adverse effects of the Three Mile Island incident and the default by the T.V.A. of their contract, some 3 600 tonnes of new uranium sales were completed during the year. The price for uranium had stabilized at US $42 - $44 by mid 1979, but by early 1980 had softened somewhat. The year 1979 saw the completion of major environmental hearings in Ontario and Newfoundland and the start of the B.C. inquiry. Two more hearings are scheduled for Saskatchewan in 1980. The Elliot Lake uranium mining expansion hearings are reviewed, as are other recent hearings. In the production of uranium for nuclear fuel cycle, environmental matters are of major concern to the industry, the public and to governments. Research is being conducted to determine the most effective method for removing radium from tailings area effluents. Very stringent criteria are being drawn up by the regulatory agencies that must be met by the industry in order to obtain an operating licence from the AECB. These criteria cover seepages from the tailings basin and through the tailings retention dam, seismic stability, and both short and long term management of the tailings waste management area. (auth)

  15. Siemens' innovative role in mining technology

    Energy Technology Data Exchange (ETDEWEB)

    1990-07-01

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

    Under the background of persistent slowdown in mining market at present, improving the management level in mining group has become the key link to improve the economic benefit of the mine. According to the practical material management in mining group, three core components of Hadoop are applied: distributed file system HDFS, distributed computing framework Map/Reduce and distributed database HBase. Material management system of mining group based on Hadoop is constructed with the three core components of Hadoop and SSH framework technology. This system was found to strengthen collaboration between mining group and affiliated companies, and then the problems such as inefficient management, server pressure, hardware equipment performance deficiencies that exist in traditional mining material-management system are solved, and then mining group materials management is optimized, the cost of mining management is saved, the enterprise profit is increased.

  17. Stop dust : a communication support for mining permit application at Bilina opencast mine

    International Nuclear Information System (INIS)

    Budinsky, V.; Paroha, L.

    2010-01-01

    This paper reported on a problem solving process called stop dust that has been launched by a brown coal mining company to improve ambient air quality and to reduce health risks for the population living in the area close to the Bilina opencast mine in the Czech Republic. The initiative also involved the efforts of local stakeholders and an independent expert team. The concept for stop dust reflected the fact that particles emitted by households through burning fossil fuels, wood, and litter in old stoves and by road transportation were much smaller and with higher health impacts, than than those emitted by coal mining activity. The paper described the Severoceske doly Company and Bilina Mine. The primary goal of stop dust was also outlined. The goal was to decrease particulate matter levels and related health risks in the communities surrounding Bilina opencast mine through feasible cost-effective measures aimed at background pollution sources. Specific topics that were addressed in the paper included particulate matter and limit values for the protection of human health; comparison of particulate matter to a hair; particulate matter dispersion modelling as part of the Bilina Mine environmental impact assessment process; and the various phases of stop dust. 3 refs., 2 tabs., 5 figs.

    1991-01-01

    This paper reports on Airlie Island which is a small (26 hectare) sand cay, located 35km north of Onslow in Western Australia. In common with other islands in the region, Airlie is a nesting site for seabirds and turtles, but its two primary conservation resources are the large Wedge-tailed Shearwater rookery which covers 64% of the island and an endemic skink species. Its conservation values have prompted the Western Australian State Government to declare the entire island a nature reserve set apart for the preservation of flora and fauna. In 1987 Western Mining Corporation Pty Ltd. developed the South Pepper and North herald oilfields and part of this development included the siting of an oil terminal on Airlie Island. It may be expected that the conservation resources of the island and the Company's requirements for land would be incompatible. However, a careful study of the local environment and the creation of a detailed plan to manage this environment resulted in an acceptable compromise

    1998-01-01

    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)

    1976-07-01

    Salient problems encountered in coal mine reclamation include land use and environmental protection values, license applications and subsequent reports, and the development of sound reclamation planning programs. The facts of life to be dealt with in reclamation and reclamation planning include encounters with negative attitudes toward reclamation, basic physics, chemistry, biology and geology, and the ability or inability to respond properly. The cooperative approach to reclamation includes interfacing with mining company personnel, government agencies, public-interest groups and consultants. Some promising solutions to reclamation, especially in alpine and subalpine regions, include handling of materials and organic test plot research.

  2. Open Source Telecommunication Companies

    2007-08-01

    Full Text Available Little is known about companies whose core business is selling telecommunications products that lever open source projects. Open source telecommunications (OST companies operate in markets that are very different from typical software product markets. The telecommunications market is regulated, vertically integrated, and proprietary designs and special chips are widely used. For a telecommunications product to be useful, it must interact with both access network products and core network products. Due to specifications in Service Agreements Levels, penalties for failures of telecommunications products are very high. This article shares information that is not widely known, including a list of OST companies and the open source projects on which they depend, the size and diversity of venture capital investment in OST companies, the nature of the commercial product-open source software and company-project relationships, ways in which OST companies make money, benefits and risks of OST companies, and competition between OST companies. Analysis of this information provides insights into the ways in which companies can build business models around open source software. These findings will be of interest to entrepreneurs, top management teams of incumbent companies that sell telecommunications products, and those who care about Ontario's ability to compete globally.

    Thallium (Tl) is an extremely toxic but little-studied element in the marine environment and practically no information has been reported on the levels of Tl in marine organisms. After the Aznalcollar mining Spill (April 1998), high levels of metals were put into the environment. This acud-contaminated medium was responsible for the initial pollution effects measured in the Guadiamar River, which is an affluent of the Guadalquivir River and very close to the biggest natural reserve in Europe (Donana). Four different species were used in the monitoring from April to September 1998 and a sediment field bioassay to check bioacumulation was performed. We present the first ecotoxicological evaluation of the mining spill in the Guadalquivir River, with reference to Tl, a little-known metal. Also, Pb and Cd data were compared to Tl during field sediment testing. Results show low levels of this metal in all of the organisms studied and they do not show any increase in the level of this metal, ranging from 40 to 90 ng g{sup -}1, 80 to 210 ng g{sup -}1, 15 to 98 ng g{sup -}1 and 75 to 125 whole body dry weight for Scrobicularia plana, Liza ramada (muscle), Crassostrea angulata and Uca Tangeri, respectively. These are the first field data of Tl concentration measured using estuarine organisms. Field sediment toxicity test results confirm those obtained during the monitoring: Tl is not bioaccumulated by the organisms (C. angulata) used in the test. The sequence in bioaccumulation of metals was Cd > Pb > Tl. Both studies, bioaccumulation and sediment toxicity, should be maintained during the next few years to really evaluate the potential effect of the mining spill on the ecosystem and society.

    1985-01-01

    The paper describes the different types of uranium deposits and their importance. It is shown that during the present depressed uranium market situation, mainly high grade deposits such as unconformity-related deposits can be mined economically. The different successive exploration steps are outlined including methods used for uranium. Uranium mining does not greatly differ from normal mining, but the uranium metallurgy needs its own specialized but already classic technology. Only a relative small amount of uranium can be expected from projects where uranium is produced by in situ leach methods or by extraction from phosphoric acid. A short summary of investment costs and operating costs is given for an average uranium mine. The last chapter deals with the definition of different reserve categories and outlines the uranium reserves of the western world including the uranium production (1983) and the expected uranium production capacity for 1985 and 1990.

    1977-07-01

    One of the most important factors in isolating the demonstration waste storage site is an adequate number of shafts to insure proper ventilation. Proper ventilation will require that the air exhausted from the storage area pass directly to the upcast air shaft. Those mines reported by this scoping contract generally conform with the two shafts per mine requirement of MESA. Three of the mines reported on have more than two shafts. Several of the mines can have additional shafts drilled in time to meet ERDA's schedule. Rough drilling costs have been cited in the report. From an economic standpoint, it is probable that the larger the mine, the greater the economic impact with regard to any dislocation of production that may be required. In some cases, such as the Retsof Mine and the Cayuga Mine, multiple shafts eliminate the probability of dislocation. Those small tonnage mines such as the Kleer at Grand Saline, Texas; the Hockley Mine near Houston and the Lyons Mine of the American Salt Company might be leased or purchased in their entirety

    The decay of demand, the bad financial results of the first half of 2009 and the hypothetical depletion of reserves must not hide a reality: oil companies are passing through the economic crisis without much trouble. Even if profits have marked time in volume (-57% for BP, -65% for Shell..), the net margins have not significantly suffered and the available cash remains comfortable (14 billion euros for Total as an example). The perspectives offered by the new offshore sites (like Santos in Brazil) added to the fabulous promises of the Iraqi market where 'majors' can now make their come-back will be the key of success of oil companies. The overall exploration-production investments should start up again by the beginning of 2011. For the only offshore drilling domain, they should rise up by 32% during the 2009-2013 period which represents a sum of 367 billion dollars. (J.S.)

    Mining activities are carried out by the older man and have provided resources, since ancient times, for their development and progress. With the discovery of fire will show the first metals that have marked the civilizations of copper, bronze and iron, and is the prehistory of the Stone Age tools that man has made from the exploitation of quarries first. The industrial revolution of the nineteenth century is linked to coal and steel, and could not conceiver of todays society without oil and gas, without silicon and coltan. But the mines are often aggressive and, despite their need and what they contribute to the development are answered by the societies where are made. during recent years there has been growing international efforts to try to make the minimum requirements of sustainable exploitation (European Directives, GMI, GRI, etc.) In AENOR, and within the Technical Committee of Standardization 22 Mining and Explosives, chaired by AITEMIN, was established the subcommittee 3, chaired by IGME, where, with the participation of all stake holders, have developed some standards on sustainable mining management sustainable mining that will be a tool available to mining companies to demonstrate their sustainable use to Society.

  13. Coal mining in Australia

    Mills, L J

    1981-12-01

    In 1959 black coal production in Australia totalled some 21.9 million tonnes per annum, 70% of this being produced from underground mines in the coalfields of New South Wales. By 1980 output levels had increased by nearly 350% to 75.4 million tonnes per annum (54% of which was exported) compared with 5% some 20 years earlier. Because it is blessed with large reserves of coal and other forms of energy, it is inevitable that the Australian coal mining industry will be required to play a major role in the development of the international coal market through to the end of the present century. Experts now predict a need for the black coal output in Australia to be developed from its present level to a minimum of 293 million tonnes per annum by the year 2000. This paper examines the present circumstances in the Australian coal industry and attempts to outline the development which has to be undertaken in order to meet the needs of an energy hungry world.

    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.

    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.

    The liberalization of the natural gas market in Europe has all kinds of juridical aspects. Not only with respect to new legislation (Natural Gas Law and Mining Law), but also changes in juridical structures of natural gas companies, caused by privatization or splitting up in a mains management company and a distribution company. In a series of articles lawyers of the Energy Working Group of Houthoff Buruma in The Hague, Netherlands, discuss the developments at the natural gas market. In this third part, attention will be paid to how authorities involved (municipalities, provinces) can prepare themselves properly with respect to selling the gas company and how they can retain their influence on the future activities of the gas company using legal and contractual agreements. In the article also attention is paid to the various stages of a sale

    Knowing what the customer thinks of a particular product/service helps top management to introduce improvements in processes and products, thus differentiating the company from their competitors and gain competitive advantages. The customers, with their preferences, determine the success or failure of a company. In order to know opinions of the customers we can use technologies available from the web 2.0 (blog, wiki, forums, chat, social networking, social commerce). From these web sites, useful information must be extracted, for strategic purposes, using techniques of sentiment analysis or opinion mining.

  1. Innovations in petroleum and mining licensing?

    Waelde, T.W.

    1992-01-01

    Issues are presented which could be regarded as recent innovations, relatively speaking, in petroleum and mining operations licensing practice. Six examples of such innovations are given. They are: the encouragement rather than restriction of private investment reflected in policies, legislation and the details of foreign investment arrangements; de-bureaucratisation and a declining emphasis on the role of the state in resource development; the gradual transition towards the role model of international resource companies which is damaging the nature of state owned petroleum and mining companies; greater flexibility in fiscal regimes; the introduction of and much greater emphasis upon, environment protection provisions; and finally, a possible change towards standardized bidding and bid evaluation in negotiations.

    , has kept attention away from the fact that as a nation Australians live beyond their means (just as the rest of the West), and they do so in one of the most catastrophically unsustainable societies in the world. In my paper I wish to look at how mining companies operating in Australia and beyond...... construct story-telling of what they are, and what they do. I want to relate this story-telling to broader issues, or let’s say competing narratives about corporate achievement, such as CSR, environmental protection and the effect on local communities where they operate. I am particularly interested...... on – in this case - an indigenous community. I also wish to look at the presence in Greenland of a large Australian owned and managed mining company involved in the exploration of ‘specialty metals’ in an area that also contains deposits of uranium. In this paper I wish to position myself between the two ways...

    During the boom years of the 2000s, the global mining industry expanded quickly, with many countries and companies investing large amounts of money in efforts to increase production and satisfy a rapidly growing global economy hungry for natural resources. Now, with lower commodity prices, decreasing ore quality and higher production costs, keeping these mines open means streamlining operations and improving productivity. Radiotracers and nucleonic gauges are among the techniques that enable the industry to achieve this increased efficiency.

  7. Ore reserve estimation of uranium deposit Zirovski vrh

    International Nuclear Information System (INIS)

    Lukacs, E.

    1979-01-01

    The uranium ore deposit Zirovski vrh is in the Permian sediments of Northwest Yugoslavia. Lenticular bodies occur at several stratiform levels in grey, medium-grained sandstone. The ore deposit will be mined entirely by underground methods. It is possible to define three stages of deposit evaluation requiring different densities of exploration effort: preliminary evaluation of in situ ore reserves; evaluation of mineable ore reserves; evaluation of production capability and mine planning. The drilling density increases markedly with each succeeding stage. The optimal drilling density for all three stages of evaluation should be determined, but there is some concern that too close spaced drilling would considerably increase the exploration costs without a corresponding increase in effectiveness. On the other hand, too sparsely spaced drilling may result in some difficulties in following the ore in mining. The paper treats the problem of the density of drilling for evaluation of mineable ore reserves compared to that required for mine planning and mine production capability. The purpose of investigation of mineral raw materials is to define economic deposits (ore bodies). To evaluate the deposit economically an accurate reserve estimate is required. If it is accordingly established that such an estimate is within the degree of admissible error, the purpose of the exploration is satisfied. However, the problem as to whether the drilling grid is sufficiently dense remains, because the majority of estimates of ore reserves do not provide a measure of the reliability of the estimate.

  8. Development of world coal reserves, their registration and their utilization

    Energy Technology Data Exchange (ETDEWEB)

    Bachmann, H

    1979-10-01

    This paper examines statistics on world coal production and world coal reserves with figures from 1860 to 1974 provided in tables and graphs. Eighty percent of the total world coal reserves (92% of world brown coal reserves) lie in the USA and USSR. The recent increase in total coal reserve estimates is due to exploration in western USA and in the USSR east of the Urals. Depth and thickness of the world's coal seams are shown in graphs and variations in coal quality are discussed. Problems associated with the anticipated substantial increase in coal production up to the year 2000 are considered. Encouraging higher coal production is the successful development of highly mechanized underground mining techniques and highly productive heavy surface mining equipment which allows excavation at increased depths. Surface mining is expected to make up 50% of total world mining operations in the near future. More complete deposit exploitation also contributes to higher coal production. Low international ship freight rates would facilitate future world coal trade. Obstacles are seen as: high, long term investments due to the fact that coal reserves lie far from populated and industrialized areas; opening new mines; transportation costs and infrastructure development.

    Throughout most of human history, environmental stewardship during mining has not been a priority partly because of the lack of applicable laws and regulations and partly because of ignorance about the effects that mining can have on the environment. In the United States, the National Environmental Policy Act of 1969, in conjunction with related laws, codified a more modern approach to mining, including the responsibility for environmental stewardship, and provided a framework for incorporating environmental protection into mine planning. Today, similar frameworks are in place in the other developed countries of the world, and international mining companies generally follow similar procedures wherever they work in the world. The regulatory guidance has fostered an international effort among all stakeholders to identify best practices for environmental stewardship.The modern approach to mining using best practices involves the following: (a) establishment of a pre-mining baseline from which to monitor environmental effects during mining and help establish geologically reasonable closure goals; (b) identification of environmental risks related to mining through standardized approaches; and (c) formulation of an environmental closure plan before the start of mining. A key aspect of identifying the environmental risks and mitigating those risks is understanding how the risks vary from one deposit type to another—a concept that forms the basis for geoenvironmental mineral-deposit models.Accompanying the quest for best practices is the goal of making mining sustainable into the future. Sustainable mine development is generally considered to be development that meets the needs of the present generation without compromising the ability of future generations to meet their own needs. The concept extends beyond the availability of nonrenewable mineral commodities and includes the environmental and social effects of mine development.Global population growth, meanwhile, has

    2016-04-01

    Located in the Iberian Pyrite Belt (IPB) northern sector, near the Portuguese/Spanish border, the outcropping São Domingos deposit was mined since Roman time. Between 1854 and 1966 the Mason & Barry Company developed open pit excavation until 120 m depth and underground mining until 420 m depth. The São Domingos subvertical deposit is associated with felsic volcanics and black shales of the IPB Volcano-Sedimentary Complex and is represented by massive sulphide and stockwork ore (py, cpy, sph, ga, tt, aspy) and related supergene enrichment ore (hematite gossan and covellite/chalcocite). Different mine waste classes were mapped around the old open pit: gossan (W1), felsic volcanic and shales (W2), shales (W3) and mining waste landfill (W4). Using the LNEG (Portuguese Geological Survey) CONASA database (company historical mining waste characterization based on 162 shafts and 160 reverse circulation boreholes), a methodology for tridimensional modelling mining waste pile was followed, and a new mining waste resource is presented. Considering some constraints to waste removal, such as the Mina de São Domingos village proximity of the wastes, the industrial and archaeological patrimony (e.g., mining infrastructures, roman galleries), different resource scenarios were considered: unconditioned resources (total estimates) and conditioned resources (only the volumes without removal constraints considered). Using block modelling (SURPAC software) a mineral inferred resource of 2.38 Mt @ 0.77 g/t Au and 8.26 g/t Ag is estimated in unconditioned volumes of waste. Considering all evaluated wastes, including village areas, an inferred resource of 4.0 Mt @ 0.64 g/t Au and 7.30 g/t Ag is presented, corresponding to a total metal content of 82,878 oz t Au and 955,753 oz t Ag.

    2011-01-01

    Deilmann-Haniel Shaft Sinking GmbH and its predecessor and associate companies have been involved in projects for underground ultimate storage in Germany, Europe and America for over 45 years. The field of activities previously comprised surveying, planning and sinking of shafts, repair and conversion work, design of underground sealing structures, planning of conveyors and support of the BfS in planning approval procedures. Following discontinuation of activities in the German coal mining industry the use of mines for ultimate storage is an important support for German specialist mining companies. The use of mines for ultimate storage ensures that the existing mining know how in Germany is maintained, because training of the younger generation on the commercial and engineering side of the companies is made possible by the imminent major projects.

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

    The Canadian Nuclear Safety Commission (CNSC) contracted an independent verification of an intensive gamma radiation survey conducted by a mining company to demonstrate that remediation of disturbed areas was complete. This site was the first of the recent mines being decommissioned in Canada and experience gained here may be applied to other mines being decommissioned in the future. The review included examination of the site-specific basis for clean-up criteria and ALARA as required by CNSC guidance. A paper review of the company report was conducted to determine if protocols were followed and that the summarized results could be independently reproduced. An independent verification survey was conducted on parts of the site and comparisons were made between gamma radiation measurements from the verification survey and the original company survey. Some aspects of data collection using rate meters linked to GPS data loggers are discussed as are aspects for data management and analyses methods required for the large amount of data collected during these surveys. Recommendations were made for implementation of future surveys and reporting the data from those surveys in order to ensure that remediation was complete. (authors)

In particular, there is the rich archival material (papers and books concerning the work of the one-time Imperial and Royal Mining Captaincies in Zagreb, Zadar, Klagenfurt and Split, A minor part of the documentation has not yet been transferred to Croatia. From mining handbooks and books we can also find out about mining in Croatia. In the context of Austro-Hungary. For example, we can find out that the first governorships in Zagreb and Zadar headed the Ban, Count Jelacic and Baron Mamula were also the top mining authorities, though this, probably from political motives, was suppressed in the guides and inventories or the Mining Captaincies. At the end of the 1850s, Croatia produced 92-94% of sea salt, up to 8.5% of sulphur, 19.5% of asphalt and 100% of oil for the Austro-Hungarian empire. From data about mining in the Split Mining Captaincy, prepared for the Philadephia Exhibition, it can be seen that in the exploratory mining operations in which there were 33,372 independent mines declared in 1925 they were looking mainly for bauxite (60,0%, then dark coal (19,0%, asphalts (10.3% and lignites (62%. In 1931, within the area covered by the same captaincy, of 74 declared mines, only 9 were working. There were five coal mines, three bauxite mines and one for asphalt. I suggest that within state institution, the Mining Captaincy or Authority be renewed, or that a Mining and Geological Authority be set ap, which would lead to the more complete affirmation of Croatian mining (the paper is published in Croatian.

    2018-06-01

    Truck crashes contribute to a large number of injuries and fatalities. This study seeks to identify the contributing factors affecting truck crash severity using 2010 to 2016 North Dakota and Colorado crash data provided by the Federal Motor Carrier Safety Administration. To fulfill a gap of previous studies, broad considerations of company and driver characteristics, such as company size and driver's license class, along with vehicle types and crash characteristics are researched. Gradient boosting, a data mining technique, is applied to comprehensively analyze the relationship between crash severities and a set of heterogeneous risk factors. Twenty five variables were tested and 22 of them are identified as significant variables contributing to injury severities, however, top 11 variables account for more than 80% of injury forecasting. The relative variable importance analysis is conducted and furthermore marginal effects of all contributing factors are also illustrated in this research. Several factors such as trucking company attributes (e.g., company size), safety inspection values, trucking company commerce status (e.g., interstate or intrastate), time of day, driver's age, first harmful events, and registration condition are found to be significantly associated with crash injury severity. Even though most of the identified contributing factors are significant for all four levels of crash severity, their relative importance and marginal effect are all different. For the first time, trucking company and driver characteristics are proved to have significant impact on truck crash injury severity. Some of the results in this study reinforce previous studies' conclusions. Findings in this study can be helpful for transportation agencies to reduce injury severity, and develop efficient strategies to improve safety.

    The Fraisse mine is one of the four underground mines of the La Crouzille mining divisions of Cogema. Faced with the necessity to mechanize its workings, this mine also had to satisfy a certain number of stringent demands. This has led to concept of four different mining methods for the four workings at present in active operation at this pit, which nevertheless preserve the basic ideas of the methods of top slicing under concrete slabs (TSS) or horizontal cut-and-fill stopes (CFS). An electric scooptram is utilized. With this type of vehicle the stringent demands for the introduction of means for fire fighting and prevention are reduced to a minimum. Finally, the dimensions of the vehicles and the operation of these methods result in a net-to-gross tonnages of close to 1, i.e. a maximum output, combined with a minimum of contamination [fr

    Estonian mineral resources are deposited in low depth and mining fields are large, therefore vast areas are affected by mining. There are at least 800 deposits with total area of 6,000 km 2 and about the same number of underground mines, surface mines, peat fields, quarries, and sand and gravel pits. The deposits cover more than 10% of Estonian mainland. The total area of operating mine claims exceeds 150 km 2 that makes 0.3 % of Estonian area. The book is written mainly for the people who are living or acting in the area influenced by mining. The observations and research could benefit those who are interested in geography and environment, who follow formation and look of mined-out landscapes. The book contains also warnings for careless people on and under the surface of the mined-out land. Part of the book contains results of the research made in 1968-1993 by the first two authors working at the Estonian branch of A.Skochinsky Institute of Mining. Since 1990, Arvi Toomik continued this study at the Northeastern section of the Institute of Ecology of Tallinn Pedagogical University. Enno Reinsalu studied aftereffects of mining at the Mining Department of Tallinn Technical University from 1998 to 2000. Geographical Information System for Mining was studied by Ingo Valgma within his doctoral dissertation, and this book is one of the applications of his study

  17. Mine water treatment

    Energy Technology Data Exchange (ETDEWEB)

    Komissarov, S V

    1980-10-01

    This article discusses composition of chemical compounds dissolved or suspended in mine waters in various coal basins of the USSR: Moscow basin, Kuzbass, Pechora, Kizelovsk, Karaganda, Donetsk and Chelyabinsk basins. Percentage of suspended materials in water depending on water source (water from water drainage system of dust suppression system) is evaluated. Pollution of mine waters with oils and coli bacteria is also described. Recommendations on construction, capacity of water settling tanks, and methods of mine water treatment are presented. In mines where coal seams 2 m or thicker are mined a system of two settling tanks should be used: in the upper one large grains are settled, in the lower one finer grains. The upper tank should be large enough to store mine water discharged during one month, and the lower one to store water discharged over two months. Salty waters from coal mines mining thin coal seams should be treated in a system of water reservoirs from which water evaporates (if climatic conditions permit). Mine waters from mines with thin coal seams but without high salt content can be treated in a system of long channels with water plants, which increase amount of oxygen in treated water. System of biological treatment of waste waters from mine wash-houses and baths is also described. Influence of temperature, sunshine and season of the year on efficiency of mine water treatment is also assessed. (In Russian)

  20. Electric shovels meet the demands for mining operations

    Energy Technology Data Exchange (ETDEWEB)

    Fiscor, S.

    2008-03-15

    Rugged, intelligent shovels offer better productivity and help mine operators avoid costly downtime in a very tight market. In 2007 P & H Mining Equipment began to produce a new breed of electric mining shovels designed to help reduce operating cost in coal and other mining operations. These were designated the P & H C-Series. All have an advanced communication, command and control system called the Centurion system. Coal mining applications for this series include 4100XPCs in Australia, China and Wyoming, USA. The Centurion system provides information on shovel performance and systems health which is communicated via graphic user interface terminals to the operators cab. Bucyrus International is developing a hydraulic crowd mechanism for its electric shovels and is now field testing one for its 495 series shovel. The company has also added greater capability in the primary software in the drive system for troubleshooting and fault identification to quickly diagnose problems onboard or remotely. 4 photos.

    As mining fields in Canada are various and numerous, the author proposes a presentation of the Canadian mining law. He first presents the administrative and legal organization of the Canadian territory with its Provinces, Territories, and sea beds. He briefly describes the distribution of constitutional competencies, outlines some geopolitical peculiarities (notably with respect to land tenure). He addressed the situation of the Quebec Province as far as the mining law is concerned. He notably comments cases which are a matter of public discussion: the acquisition of a mining permit (a claim) by a mining company in a residential area, the search for shale gas in the Saint-Laurent valley, the exploitation of oil sands, a project of pipeline. He comments the legal framework for a claim acquisition, the case of surface mineral substances, and the case of hydrocarbons. He presents and comments the legal regime of environmental authorizations in Quebec

  2. Peabody Western brings its old mines into new competitive era

    Energy Technology Data Exchange (ETDEWEB)

    Sprouls, M.W.

    1994-10-01

    Peabody Western Coal Co., manages four surface mines that mark Peabody's expansion from the Midwest to the West. The mines began operating between 1964 and 1973, before the surge of western coal mine start-ups brought about by the oil price shock of 1973 and 1974 and the subsequent investments in coal by American oil companies. Despite good demand for western low-sulfur coals, the prices are low due to production overcapacity that was built in the 1970s. The result is that older mines have had to be creative to reduce costs and retain customers amid stiff competition. The mining units - Black Mesa and Kayenta in Arizona, Big Sky in Montana and Seneca in Colorado - now must handle coal supply administration, financial analysis, engineering, environmental compliance, labor relations and community relations at their sites. Peabody Western's Flagstaff, Ariz., headquarters staff will be reduced by about 30 people, although many of them will be assigned to mining units. All four surface mines use draglines, and each supplies a primary customer, but the mines have as many differences as similarities. Altogether, the mines produce about 17 million tons annually and employ 1,100 people.

  3. Protecting reliability of mining at individual levels against phase conflict at the Belchatow mine and power plant

    Energy Technology Data Exchange (ETDEWEB)

    Sztandera, T [Akademia Gorniczo-Hutnicza, Cracow (Poland)

    1988-01-01

    Discusses problems of overburden removal and mining at the Belchatow brown coal surface mine in Poland. The analysis is based on the results of the statistical data on surface mining in Belchatow from 1985 to 1987. Information on number of benches, their dimensions (height, width), slope inclination and volume of overburden is evaluated. The analysis showed that time delay from overburden removal to coal mining is excessively low; reserves of coal ready for mining are too low, especially in winter. This phenomenon is illustrated by the increasing slope inclinations of the whole cut in winter as the mine yields coal reserves made ready for excavation. In summer the rate of overburden removal increases. Such seasonal fluctuations negatively affect safety conditions in winter and especially in spring when increased content of moisture in sedimentary rocks reduce their resistance to landslide. 5 refs.

The differences in the interpretation of economic, market and marketing potential of the company are identified, although they are related to the subject of entrepreneurship, but they differ in their essence. The substantiation of the essence of marketing potential of the company, the development of an effective mechanism of its management with the possibility of evaluation will contribute to the maximum satisfaction of interests of information consumers’ groups, the formation of strategic directions of the activity, making management decisions at the micro level, the effective functioning in the internal and external markets.

  19. HYDROCARBONS RESERVES IN VENEZUELA

    Energy Technology Data Exchange (ETDEWEB)

    Gonzalez Cruz, D.J.

    2007-07-01

    Venezuela is an important player in the energy world, because of its hydrocarbons reserves. The process for calculating oil and associated gas reserves is described bearing in mind that 90% of the gas reserves of Venezuela are associated to oil. Likewise, an analysis is made of the oil reserves figures from 1975 to 2003. Reference is also made to inconsistencies found by international experts and the explanations offered in this respect by the Ministry of Energy and Petroleum (MENPET) and Petroleos de Venezuela (PDVSA) regarding the changes that took place in the 1980s. In turn, Hubbert's Law is explained to determine peak production of conventional oil that a reservoir or field will reach, as well as its relationship with remaining reserves. Emphasis is placed on the interest of the United Nations on this topic. The reserves of associated gas are presented along with their relationship with the different crude oils that are produced and with injected gas, as well as with respect to the possible changes that would take place in the latter if oil reserves are revised. Some recommendations are submitted so that the MENPET starts preparing the pertinent policies ruling reserves. (auth)

  2. Elliot Lake uranium mine reclamation, the first ten years

    International Nuclear Information System (INIS)

    Payne, R.A.

    2000-01-01

    In 1989, Rio Algom Limited finalized its plans for the closure and subsequent decommissioning of two of its then three operating mines in Elliot Lake as a result of market conditions. These two mines closed in August 1990. These mine closures had significant impacts. The principal mining operations of Rio Algom at that time were still in Elliot Lake and had been the very foundation of the company for about 40 years. The business impact on the Corporation was regarded as possibly severe. The resultant layoff of over 1,500 long-term, highly qualified, skilled and well-paid employees, a devastating blow to the affected employees and their families, would have a significant financial impact on the municipal economy, particularly as this announcement was seen as the first step in the early closure of all four operating mines in the region. At that time there was little precedence for such a high profile mine closure program and consequently the many unknowns relating to the mine decommissioning process, legislative requirements and society's expectations resulted in a perception of a significant yet ill-defined liability. In this atmosphere of understandable company, stakeholder and public concern, Rio Algom Limited embarked on what has turned out to be a long, rigorous, challenging yet ultimately reasonable and rewarding process of progressive reclamation of all its Elliot Lake mines, some ten in total (nine uranium, one copper). Over the past ten years, reclamation of all ten mines has been successfully completed, some $70 m plus has been expended in direct site reclamation works and the workforce has been reduced from over 2,500 to just 4. After ten years, the focus of attention is now on the long-term care, maintenance, monitoring and reporting required for the decommissioned mine sites, and the accomplishment of this in the best interests of all the stakeholders.

  3. Women in mining still exploited and sexually harassed

    Directory of Open Access Journals (Sweden)

    Doret Botha

    2016-11-01

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

    Although mining companies have long been conscious of water related risks they still face environmental management problems. These problems mainly emerge because mine sites' water balances have not been adequately assessed in the stage of the planning of mines. More consistent approach is required to help mining companies identify risks and opportunities related to the management of water resources in all stages of mining. This approach requires that the water cycle of a mine site is interconnected with the general hydrologic water cycle. In addition to knowledge on hydrological conditions, the control of the water balance in the mining processes require knowledge of mining processes, the ability to adjust process parameters to variable hydrological conditions, adaptation of suitable water management tools and systems, systematic monitoring of amounts and quality of water, adequate capacity in water management infrastructure to handle the variable water flows, best practices to assess the dispersion, mixing and dilution of mine water and pollutant loading to receiving water bodies, and dewatering and separation of water from tailing and precipitates. WaterSmart project aims to improve the awareness of actual quantities of water, and water balances in mine areas to improve the forecasting and the management of the water volumes. The study is executed through hydrogeological and hydrological surveys and online monitoring procedures. One of the aims is to exploit on-line water quantity and quality monitoring for the better management of the water balances. The target is to develop a practical and end-user-specific on-line input and output procedures. The second objective is to develop mathematical models to calculate combined water balances including the surface, ground and process waters. WSFS, the Hydrological Modeling and Forecasting System of SYKE is being modified for mining areas. New modelling tools are developed on spreadsheet and system dynamics platforms to

    2017-12-01

    Full Text Available The key processes in the business of insurance companies which define the financial viability of their business activities, as the most important element, are the adequate amount of technical reserves. A qualitative assessment of the technical reserves level is the basic support to the management of the key business processes and proper strategic and financial decision-making in order to maximize the viability, profitability, competitiveness, and further development of the company. Based on the data on the operations of an insurance company, within a single line of insurance, different, in practice, most frequently used methods were applied in order to determine the deviation amplitude of the projected amounts from the actual claims. Another direction of research focuses on actuarial practice in non-life insurance companies operating in the territory of the Republic of Serbia. The comparative analysis of the obtained projection points to the fact that the chosen methods, commonly used in actuarial practice in the Republic of Serbia, should be monitored and reviewed. The results of the multidirectional research and detection of the existing problems provide a useful framework and a stimulating mechanism, as well as the guidelines to improve the operations and better positioning of insurance in the commercial and economic environment of the Republic of Serbia.

    Environmental communication is becoming a sine qua non for companies which are more and more pressed by the need to reinforce communication with interested parties: environmental groups, local communities, local and national authorities, employees, share-holders, banks, insurance companies, customers and consumers. Reliable environmental information, just like economical and property data, is now required during both company take-over and financing, and in some cases it can affect insurance premiums. In fact, environmental guarantees are more and more often required because breaching environmental regulations can entail legal sanctions going as far as suspension of business. There now also Green investment funds that engage their resources only against specific environmental guarantees on the part of the companies that, before being selected for the investment, are submitted to rather accurate questionnaires by the investment manager [it

    1997-12-31

    Historic mining created new roosting habitat for many bat species. Now the same industry has the potential to adversely impact bats. Contemporary mining operations usually occur in historic districts; consequently the old workings are destroyed by open pit operations. Occasionally, underground techniques are employed, resulting in the enlargement or destruction of the original workings. Even during exploratory operations, historic mine openings can be covered as drill roads are bulldozed, or drills can penetrate and collapse underground workings. Nearby blasting associated with mine construction and operation can disrupt roosting bats. Bats can also be disturbed by the entry of mine personnel to collect ore samples or by recreational mine explorers, since the creation of roads often results in easier access. In addition to roost disturbance, other aspects of renewed mining can have adverse impacts on bat populations, and affect even those bats that do not live in mines. Open cyanide ponds, or other water in which toxic chemicals accumulate, can poison bats and other wildlife. The creation of the pits, roads and processing areas often destroys critical foraging habitat, or change drainage patterns. Finally, at the completion of mining, any historic mines still open may be sealed as part of closure and reclamation activities. The net result can be a loss of bats and bat habitat. Conversely, in some contemporary underground operations, future roosting habitat for bats can be fabricated. An experimental approach to the creation of new roosting habitat is to bury culverts or old tires beneath waste rock. Mining companies can mitigate for impacts to bats by surveying to identify bat-roosting habitat, removing bats prior to renewed mining or closure, protecting non-impacted roost sites with gates and fences, researching to identify habitat requirements and creating new artificial roosts.

    The author relates his experience in the development of a spinal implant development company (K2M) that is significantly advised by physicians. To provide information about the development of a spinal implant company (K2M) advised by a group of professional spinal surgeons. To relate the federal laws (STARK and anti-kickback) as they pertain to surgeon-influenced companies. To discuss the role of a scientific advisory board. A self-developed company was developed together with significant, but minority physician financial input and majority scientific advice. A privately owned spinal implant development corporation (K2M) was developed 3 years ago. Physician financial participation was less than 20% (Stark laws state no more than 40%). Users of product are greater than 60% non-investor physicians. The development of a large scientific advisory board has been very influential in product development. A privately owned spinal implant company (K2M) has been developed strictly within Federal laws. Its board of scientific advisors that receives recompense commissurate only with effort significantly impacts the company policy.

    Data mining facilitates the study of radiology data in various dimensions. It converts large patient image and text datasets into useful information that helps in improving patient care and provides informative reports. Data mining technology analyzes data within the Radiology Information System and Hospital Information System using specialized software which assesses relationships and agreement in available information. By using similar data analysis tools, radiologists can make informed decisions and predict the future outcome of a particular imaging finding. Data, information and knowledge are the components of data mining. Classes, Clusters, Associations, Sequential patterns, Classification, Prediction and Decision tree are the various types of data mining. Data mining has the potential to make delivery of health care affordable and ensure that the best imaging practices are followed. It is a tool for academic research. Data mining is considered to be ethically neutral, however concerns regarding privacy and legality exists which need to be addressed to ensure success of data mining

  20. Petroleum reserves in West Africa: an overview

    International Nuclear Information System (INIS)

    Copinschi, Ph.; Favennec, J.P.

    1999-01-01

    The Gulf of Guinea region in West Africa is one in which production and reserves have increased the most during the last few years, essentially due to offshore operation. It is also there that the most spectacular discoveries have been made in recent years, particularly with deep-sea drilling. The low production costs and enthusiastic welcome for foreign investors make the region a favoured destination for large international companies, even if uncertainties and political tensions remain to make the situation delicate. In these conditions, the relationship between the host State and the foreign petrol companies are changing. Beyond the purely formal aspects of these new contacts, the whole former system of 'reserved markets' is being threatened by the increasing tendency to open the sector to competition. Eight countries are examined in detail: Nigeria, Angola, Gabon, Congo, Cameroon, Equatorial Guinea, the Ivory Coast and Chad. (authors)

  3. Injection of alkaline ashes into underground coal mines for acid mine drainage abatement

    Aljoe, W.W.

    1996-01-01

    The injection of alkaline coal combustion waste products into abandoned underground coal mines for acid mine drainage (AMD) abatement has obvious conceptual appeal. This paper summarizes the findings of the baseline hydrogeologic and water quality evaluations at two sites--one in West Virginia and one in Maryland--where field demonstrations of the technique are being pursued in cooperative efforts among State and Federal agencies and/or private companies. The West Virginia site produces severe AMD from three to seven AMD sources that are spaced over about a 1.2 km stretch of the down-dip side of the mine workings. By completely filling the most problematic portion of the mine workings with coal combustion ashes, the State expects that the costs and problems associated with AMD treatment will be greatly reduced. At the Maryland site, it is expected that the AMD from a relatively small target mine will be eliminated completely by filling the entire mine void with a grout composed of a mixture of fly ash, fluidized-bed combustion ash, and flue gas desulfurization sludge. This project will also demonstrate the potential cost-effectiveness of the technique at other sites, both for the purpose of AMD remediation and control of land subsidence

    This project evolved from a 1995, DOE-NETL competitive solicitation for practical CMM capture and utilization concepts. Appalachian Pacific was one of three companies selected to proceed with the construction and operation of a cost-shared demonstration plant. In the course of trying to proceed with this demonstration plant, AP examined several liquefaction technologies, discussed obtaining rights to coal mine methane with a number of coal companies, explored marketing potential with a wide variety of customers in many sections of the United States, studied in great detail the impact of a carbon credit exchange, and developed a suite of analytical tools with which to evaluate possible project options. In the end, the newness of the product, reluctance on the part of the coal companies to venture away from time tested practices, difficulty with obtaining financing, the failure of a carbon credit market to develop and the emergence of shale derived gas production prevented a demonstration plant from being built.

    Problems in the post-mining regions of Eastern Europe range from degraded land and landscapes, huge insecure dumps, surface cracks, soil pollution, lowering groundwater table, deforestation, and damaged cultural potentials to socio economic problems like unemployment or population decline. There is no common prescription for tackling the development of post-mining regions after mine closure nor is there a common definition of good practices or policy in this field. Key words : waste management, legislation, EU Directive, post mining Rosia Montana is a common oh 16 villages; one of them is also called Rosia Montana, a traditional mining Community, located in the Apuseni Mountains in the North-Western Romania. Beneath part of the village area lays one of the largest gold and silver deposits in Europe. In the Rosia Montana area mining had begun ever since the height of the Roman Empire. While the modern approach to mining demands careful remediation of environmental impacts, historically disused mines in this region have been abandoned, leaving widespread environmental damage. General legislative framework Strict regulations and procedures govern modern mining activity, including mitigation of all environmental impacts. Precious metals exploitation is put under GO no. 190/2000 re-published in 2004. The institutional framework was established and organized based on specific regulations, being represented by the following bodies: • The Ministry of Economy and Commerce (MEC), a public institution which develops the Government policy in the mining area, also provides the management of the public property in the mineral resources area; • The National Agency for the development and implementation of the mining Regions Reconstruction Programs (NAD), responsible with promotion of social mitigation measures and actions; • The Office for Industry Privatization, within the Education Ministry, responsible with privatization of companies under the CEM; • The National

    2016-04-01

    The implementation of novel systems and adoption of improvised equipment in mines help mining companies in two important ways: enhanced mine productivity and improved worker safety. There is a substantial need for adoption of state-of-the-art automation technologies in the mines to ensure the safety and to protect health of mine workers. With the advent of new autonomous equipment used in the mine, the inefficiencies are reduced by limiting human inconsistencies and error. The desired increase in productivity at a mine can sometimes be achieved by changing only a few simple variables. Significant developments have been made in the areas of surface and underground communication, robotics, smart sensors, tracking systems, mine gas monitoring systems and ground movements etc. Advancement in information technology in the form of internet, GIS, remote sensing, satellite communication, etc. have proved to be important tools for hazard reduction and disaster management. This paper is mainly focused on issues pertaining to mine safety and disaster management and some of the recent innovations in the mine automations that could be deployed in mines for safe mining operations and for avoiding any unforeseen mine disaster.

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

  8. The economic efficiency of investment in the development of reserves of small groups of geographically contiguous gold deposits

    Directory of Open Access Journals (Sweden)

    Evdokimov S.I.

    2017-01-01

    Full Text Available The object of the research is a group of geographically contiguous low volume gold deposits. The subject of the study is an economic justification for a way to involve economic turnover to get a positive commercial result on a specially formed group of gold deposits, in which individual field development is unprofitable. A small production volume, combined with high capital and operating costs are objective reasons for the reduction in investment attractiveness of the deposits which have reserves of gold of 50%, equipped with a mobile processing complex with deep processing technology on highly liquid commodity products on site. An economic-mathematical model was devised to determine the rational placement of the processing capacity of the group.A simulation was conducted and an economic evaluation was performed on the effectiveness of investments in individual and group mining projects. The simulation results show that the joint exploitation of the reserves of the group of deposits, the internal rate of return on investments exceed the rate of return of funds to the bank deposit, the return on investment is above the level of inflation. The group project complies with the strategic line of small mining companies in terms of cost recovery terms, availability of financial sources to cover expenses, provision of stable means of income and obtaining competitive advantage.

    Rogowitz, Bernice E.; Rabenhorst, David A.; Gerth, John A.; Kalin, Edward B.

    1996-04-01

    This paper describes a set of visual techniques, based on principles of human perception and cognition, which can help users analyze and develop intuitions about tabular data. Collections of tabular data are widely available, including, for example, multivariate time series data, customer satisfaction data, stock market performance data, multivariate profiles of companies and individuals, and scientific measurements. In our approach, we show how visual cues can help users perform a number of data mining tasks, including identifying correlations and interaction effects, finding clusters and understanding the semantics of cluster membership, identifying anomalies and outliers, and discovering multivariate relationships among variables. These cues are derived from psychological studies on perceptual organization, visual search, perceptual scaling, and color perception. These visual techniques are presented as a complement to the statistical and algorithmic methods more commonly associated with these tasks, and provide an interactive interface for the human analyst.

    The trends and factors currently emerging are likely to have significant influence on the way the upstream oil and gas industry evolves in the coming decade. This paper discusses how these trends might influence events in the 1990s, particularly how they might influence relationships between host countries and companies in the oil industry. State owned companies will dominate the industry in resource terms. These statcos fall into three groups: a small group of technically able, financially sound, well-managed companies; a group of consumer statcos that have limited domestic production but significant domestic demand; a large group that are finding it difficult to maintain their production facilities in good standing to maximize recovery from their resources. This paper describes the future private sector as consisting of the Surviving Sisters and smaller, private companies very active in the upstream. How will these various players behave in the years to come? Conventional activity in the upstream will continue as companies seek to optimize their upstream portfolios

  17. The role of public consultation in leading practice uranium mining

    International Nuclear Information System (INIS)

    Vance, R.

    2014-01-01

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

    2016-01-01

    This handbook presents the basic aspects of actuarial loss reserving. Besides the traditional methods, it also includes a description of more recent ones and a discussion of certain problems occurring in actuarial practice, like inflation, scarce data, large claims, slow loss development, the use of market statistics, the need for simulation techniques and the task of calculating best estimates and ranges of future losses. In property and casualty insurance the provisions for payment obligations from losses that have occurred but have not yet been settled usually constitute the largest item on the liabilities side of an insurer's balance sheet. For this reason, the determination and evaluation of these loss reserves is of considerable economic importance for every property and casualty insurer. Actuarial students, academics as well as practicing actuaries will benefit from this overview of the most important actuarial methods of loss reserving by developing an understanding of the underlying stochastic models...

  9. Panorama of mining activities in France during 1995

    International Nuclear Information System (INIS)

    Michel, J.C.; Bornuat, M.; Mouron, R.

    1996-01-01

    The French mining industry in 1995 continued to follow the overall trend of the past 5 to 10 years characterized mainly by: 1)a decline in the production of most energy materials: oil, coal, uranium. This decline will probably be further accentuated over the next two years with the planned closure of Lodeve (U), Forbach, La Mure and Carmaux (coal). Gas production, however, has remained relatively stable at 4.7 to 5 billion m''3 per year. 2)a scarcity of metal ore mines in Metropolitan France 3)an increase in the production of gold that, in 1995, came close to 6 tonnes in Metropolitan France and reached 8.4 tonnes with French Guiana. 4)the development of metal ore mining in the DOM-TOM 5) divergent developments in the industrial mineral sector: downward trends for sulfur, talc, andalusite, diatomite and silica; upward trends for kaolin, mica, feldspar and salt. Although overall the decline in mine production continued, the panorama does include some positive aspects: 1)France's independence in the energy sector exceeded the half-way mark two years ago and 1995 saw an appreciable decrease in the nation's energy bill compared to 1994. 2)French companies involved in metal mining have adapted themselves to world trends: Cogema has diversified its uranium sources mainly through its mining interests in Canada; Eramet has strengthened its activities by becoming the majority shareholder of Comilog, a manganese producer in Gabon. France also has mining interests in Africa, South America and Europe through LaSource Compagnie Miniere (BRGM and Normandy) created in 1995 3) France's position and production in the industrial mineral sector are significant at European scale, if not at world scale, as regards andalusite, diatomite, kaolin, mica, feldspar, sulfur, potassium, salt and industrial silica. Finally, mention must be made of the increasing environmental awareness by the French authorities and mining companies. This has resulted in a major rehabilitation of mine sites by

  10. Standardized emissions inventory methodology for open-pit mining areas.

    Huertas, Jose I; Camacho, Dumar A; Huertas, Maria E

    2011-08-01

    There is still interest in a unified methodology to quantify the mass of particulate material emitted into the atmosphere by activities inherent to open-pit mining. For the case of total suspended particles (TSP), the current practice is to estimate such emissions by developing inventories based on the emission factors recommended by the USEPA for this purpose. However, there are disputes over the specific emission factors that must be used for each activity and the applicability of such factors to cases quite different to the ones under which they were obtained. There is also a need for particulate matter with an aerodynamic diameter less than 10 μm (PM(10)) emission inventories and for metrics to evaluate the emission control programs implemented by open-pit mines. To address these needs, work was carried out to establish a standardized TSP and PM(10) emission inventory methodology for open-pit mining areas. The proposed methodology was applied to seven of the eight mining companies operating in the northern part of Colombia, home to the one of the world's largest open-pit coal mining operations (∼70 Mt/year). The results obtained show that transport on unpaved roads is the mining activity that generates most of the emissions and that the total emissions may be reduced up to 72% by spraying water on the unpaved roads. Performance metrics were defined for the emission control programs implemented by mining companies. It was found that coal open-pit mines are emitting 0.726 and 0.180 kg of TSP and PM(10), respectively, per ton of coal produced. It was also found that these mines are using on average 1.148 m(2) of land per ton of coal produced per year.

It concentrates upon legal personhood and relates this particular feature to the issue of corporate citizenship. In turn...... corporate citizenship provides a link to considering the political role of companies, since in claiming citizenship they are implicitly at least claiming a particular set of political rights consequent upon that status, and announcing a particular politically constrained context associated...... with their operational characteristics. But what would be involved in granting companies full citizenship rights in the image of natural person citizenship?

The goal of this paper is to contribute to the existing literature by examining Chinese enterprises expanding into Switzerland. The study also allows some conclusions for Chinese companies entering Central and Eastern Europe. We analyze via interviews the motivations of Chinese companies to expand into Switzerland as well as their behavior and the impediments in their internationalization process. Our findings show that Chinese companies fail to take advantage of certain benefits of western economies (such as open information and stable rule of law. To move forward efficiently, they should develop competence in dealing systematically with readily available market information, building professional networks that recognize a separation between business life and personal life, and managing their Chinese and foreign employees in the foreign cultural environment.

  14. data mining in distributed database

    as we march into the age of digital information, the collection and the storage of large quantities of data is increased, and the problem of data overload looms ominously ahead. it is estimated today that the volume of data stored by a company doubles every year but the amount of meaningful information is decreases rapidly. the ability to analyze and understand massive datasets lags far behind the ability to gather and store the data. the unbridled growth of data will inevitably lead to a situation in which it is increasingly difficult to access the desired information; it will always be like looking for a needle in a haystack, and where only the amount of hay will be growing all the time . so, a new generation of computational techniques and tools is required to analyze and understand the rapidly growing volumes of data . and, because the information technology (it) has become a strategic weapon in the modern life, it is needed to use a new decision support tools to be an international powerful competitor.data mining is one of these tools and its methods make it possible to extract decisive knowledge needed by an enterprise and it means that it concerned with inferring models from data , including statistical pattern recognition, applied statistics, machine learning , and neural networks. data mining is a tool for increasing productivity of people trying to build predictive models. data mining techniques have been applied successfully to several real world problem domains; but the application in the nuclear reactors field has only little attention . one of the main reasons, is the difficulty in obtaining the data sets

  15. Collaborative Data Mining

    Moyle, Steve

    Collaborative Data Mining is a setting where the Data Mining effort is distributed to multiple collaborating agents - human or software. The objective of the collaborative Data Mining effort is to produce solutions to the tackled Data Mining problem which are considered better by some metric, with respect to those solutions that would have been achieved by individual, non-collaborating agents. The solutions require evaluation, comparison, and approaches for combination. Collaboration requires communication, and implies some form of community. The human form of collaboration is a social task. Organizing communities in an effective manner is non-trivial and often requires well defined roles and processes. Data Mining, too, benefits from a standard process. This chapter explores the standard Data Mining process CRISP-DM utilized in a collaborative setting.

  16. Coal mine site reclamation

    Coal mine sites can have significant effects on local environments. In addition to the physical disruption of land forms and ecosystems, mining can also leave behind a legacy of secondary detrimental effects due to leaching of acid and trace elements from discarded materials. This report looks at the remediation of both deep mine and opencast mine sites, covering reclamation methods, back-filling issues, drainage and restoration. Examples of national variations in the applicable legislation and in the definition of rehabilitation are compared. Ultimately, mine site rehabilitation should return sites to conditions where land forms, soils, hydrology, and flora and fauna are self-sustaining and compatible with surrounding land uses. Case studies are given to show what can be achieved and how some landscapes can actually be improved as a result of mining activity.

  17. Treating mine water

    Energy Technology Data Exchange (ETDEWEB)

    1980-10-01

    Taking into account the negative influence of mine waters with suspended matter on the natural environment on the surface, the maximum treatment of mine water underground, is proposed. It is noted that full treatment of mine water, using conventional filtration methods, would be rather expensive, but a limited treatment of mine water is possible. Such treated mine water can be used in dust suppression and fire fighting systems. Mine water treated underground should be free of any odor, with pH level ranging from 6 to 9.5, with suspended matter content not exceeding 50 mg/l and coli-titre not less than 300 cm$SUP$3. It is suggested that water treatment to produce water characterized by these parameters is possible and economical. Recommendations on construction of underground sedimentation tanks and channels, and a hydraulic system of cleaning sedimentation tanks are proposed. The settling would be stored underground in abandoned workings. (2 refs.) (In Russian)

  18. RESTRUCTURING COMPANIES UNDER CRISIS

    Full Text Available Nobody is planning to fail, but many companies are failing because of lack of planning. Real business experience showed during the years that crisis can be prevented, avoided or limited. If detected in time, the risks associated with the crisis can be mitigated and the effects can be diminished, with the condition that the actions required are done fast, in a sharp and accurate manner. When it comes, a crisis brings an intense level of pressure and under these conditions there is no time or room for mistakes. Delays, losing focus and lack of planning will bring a company one step away from failure. The right way to deal with crisis, if required measures are not done in time, is to minimize the losses and reposition in the best way possible. Analysing the success stories of some of the biggest and strongest companies in the world, led to an important conclusion: the majority of these companies were in the situation to face huge crises which threatened their ability to survive in certain moments, on their way to success. With the right planning and by setting a proper organisational structure, the negative aspects of the crisis can be turned into benefits and opportunities for the company. The most critical challenge for management is to assess the level of exposure to risk of the company and identify the key points to focus on in order to overcome the crisis and create value. In order to set up a strong plan in dealing with crisis, a business organisation needs reliable, efficient and effective tools and this is what this article is all about.

    The Genesee Mine produces 5.5 million tonnes of coal annually for the Genesee Power Plant run by Capital Power. The mine operators place much emphasis on safety and have achieved 22 consecutive years without a lost time accident, which is as long as the mine has been in operation. After recently accepting its tenth safety award, the company recognizes that it must avoid complacency. Employees were asked their opinions regarding the company's safety record. The employee response was that positive attitudes contribute to the safe work environment, together with competent trainers, employee interest in the condition of equipment, good communication, and good leadership. The on-site workforce now encompasses over 160 employees. The ISO 9000 and 14001 and other standards and policies have not only driven the safety program, but the safety performance to date has set the bar high. A hazard assessment program requires that crew be responsive to safety indicators every day. 1 fig.

  1. Planning outstanding reserves in general insurance

    2017-10-01

    Each insurance company have to ensure its solvency through presentation of accounts for its own reserves in the start of the year. Usually the task of the actuary is to estimate the state of the company on an annual basis and the expectation of the status of the company for a future period. One of the major problem when calculating the liabilities of the incurred claims, is related to the delay of payments. Object of consideration in the present note are the outstanding claim reserves, which are set aside to cover claims, occurred before the date of the annual account, but still not paid, and related with them expenses. There may be different reasons for the delay of claims settlement. For example, continuation the process of the liquidation of the damage waiting for necessary documents or the presence of controversial cases whose permission takes time, etc. Thus the claims, which determine the outstanding reserves could be divided in the following types: claims, which are reported, but not settled (RBNS); claims, which are incurred but not reported (IBNR); claims, whose case is finished, but it is possible to be reopened. When calculating the reserves for IBNR claims, most widely used is the Chain-ladder method and its modification presented by the Bornhuetter - Ferguson method. For modeling the outstanding claims, the available data should be presented in so called run-off triangle, which underlies in the basis of such methods. The present work provides a review of the algorithm for calculating insurance outstanding claim reserves according to the Chain-ladder method. Using available data for claims related to liability of drivers, registered in Bulgaria an example is constructed to illustrate the methodology of the Chain-Ladder method. Back-testing approach is used for validating the results.

    Full Text Available A company’s manager has to create and maintain a healthy internal control system. An efficient internal control system implies the implementation in the company of risk management. Each company, but also each individual, who tries to attain certain objectives, establishes the activities which lead to the achievement of goals and, at the same time, tries to identify as many “threats” as possible, in order to take the necessary measures to eliminate them. Thus, even if one is not familiar with the concepts of risk and risk management, one acts, consciously or not, for that purpose.

    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.

    Four coal seams, with a total thickness of 16 m, are in production at this opencast mine in the Transvaal; the first coal was mined in 1978. The overburden is stripped by three draglines, and the coal is worked with one shovel and three front-end loaders. Daily production capacity is 28 000 t of coal. The preparation plant has a rated throughput of 1750 t of run-of-mine coal per hour. 5 mt of coal were mined in 1981 and dispatched to Richards Bay, from where the coal is shipped to Western industrial nations. Some 200 million R were invested in the opencast mine, the preparation plant and the infrastructure. Company policy is much concerned with the training and education of the people on the mine; 25% of the personnel attended training courses last year. Pay categories are established in relation to the Peterson evaluation plan; jobs are graded from Group 1 (the lowest) to Group 15 (the grade of the General Manager). The current minimum wage is 214 to 231 R and is well above the living level and the cost of living. The employees live in Company one-family houses, or in bachelor accommodation in the case of unmarried employees. The quality of housing is exactly the same for Blacks and Whites. The housing estates include recreational facilities, sportsfields, a primary school, a clinic, a central restaurant and shops. The present article also gives details of leave entitlements and pensions.

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

    Full Text Available When we think about promotion in financial investment services companies, we have to consider, not only the offline or traditional type of promotion (personal communication, advertising, sales promotion, public relations and organization identity but online promotion as well. Due to the fact that for more and more people, Internet represents the most important mean of communication, financial investment services companies marketing specialists have a variety of tools at hand. In this study we will describe the most important online promotion tools, like: E-mail Marketing, advertising, search engines, networks socialization, M-Marketing and promotion through web pages. Specific methods of online promotion enable real-time knowledge of the investor’s behavior and can also address to them most effectively. The purpose of this theoretical study is to increase the rate of knowledge and usage of online marketing, in a very conservatory sector of the financial market: Financial Investment Services Companies Marketing. By promoting online a company, a product or a service the marketing specialists can target specific customer, segments and quantify results, which is almost impossible on such a scale and with such precision by traditional methods of promotion. Based on the literature and our own experience, methods were taken up and adapted in financial investment services companies. We show the present state of online marketing, make proposals and describe difficulties which can be encountered when an e-marketing strategy is made. The conclusion of our study is that more and more companies use online tools in their marketing strategies. There is a change in attitude by the Financial Investment Services Companies web pages: from a reserved one in 2010 to one open to innovation in 2015; we believe that SSIF Broker is an illustrative example in this regard. Instead, our opinion is that Search Engine Optimization should be used more by SSIF Broker

    2013-05-01

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