    1989-06-01

    Within Germany, subsidies to the domestic coal industry are raising taxes, increasing electricity prices, constraining industry competitiveness and causing distortions to resource allocation decisions. Coal assistance policies raise the costs of German industry, particularly those which use coal and electricity. In the case of assistance to steaming coal production, subsidies are less explicit, making the direct cost of continued support to the industry less obvious. If Germany deregulated its coal industry, it would become a major coal importer, conceivably importing as much as 60 Mt a year. Such an increase in import demand would raise world coal trade volume significantly. The impact of liberalisation on world coal prices would depend on the extent and timing of liberalisation and the responsiveness of suppliers to the increased import demand. 13 refs., 5 figs., 2 tabs.

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

  4. 'Heat Market Campaign' of the German coal mining industry

    Dach, G.

    1983-12-22

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

  5. Methane in German hard coal mining

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

    1995-01-01

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

  14. Future prospects of the brown coal of central and east Germany in the all-German energy industry. Perspektive der mittel- und ostdeutschen Braunkohle in der gesamtdeutschen Energiewirtschaft

    Energy Technology Data Exchange (ETDEWEB)

    Milojcic, G

    1991-04-01

    Against a background of different basic conditions the energy industry in the former German Democratic Republic during the last 30 years underwent an entirely different development to that which occurred in the former Federal Republic of Germany. In the Federal Republic, oriented to a free market system, a structural change took place from the 1960s onwards, that is to say, away from solid fuels and towards a mixed energy utilization, in which mineral oil and natural gas in particular play a significant part. The principal market for coal, especially brown coal, is the important power generation sector. The German Democratic Republik, on the other hand, in keeping with its autarchic energy policy relied on the only source of energy available in large quantities, namely brown coal. The reason for this lay in the fact that the system made it impossible to participate in an international exchange of commidities. As a result of the ton-quota ideology and inefficiency in all sectors of energy winning, conversion and utilization the consumption both of primary energy and also of electricity in the former German Democratic Republic was high compared to that in the Federal Republic, and this in spite of the fact that the per capita economic strength was less than half that of the Federal Republic. Two changes are likely to occur in future. On the one hand, a medium-term mixed energy utilization will develop in the primary energy sector, as has been the case in the Federal Republic. On the other hand, it can be assumed that simultaneously with this development consumption will tend to decrease. As in the Federal Republic, the future prospect to brown coal, which has hitherto played a dominating role, will in the first place lie in its utilization in conjunction with the power industry and only secondarily on the thermal energy market.

    1979-01-01

    The effects of the National Energy Act on the use of coal in US industrial and utility power plants are considered. Innovative methods of using coal in an environmentally acceptable way are discussed: furnace types, fluidized-bed combustion, coal-oil-mixtures, coal firing in kilns and combustion of synthetic gas and liquid fuels. Fuel use in various industries is discussed with trends brought about by uncertain availability and price of natural gas and fuel oils: steel, chemical, cement, pulp and paper, glass and bricks. The symposium on Industrial Coal Utilization was sponsored by the US DOE, Pittsburgh Energy Technology Center, April 3 to 4, 1979. Twenty-one papers have been entered individually into the EDB.

  16. The Indonesian coal industry

    International Nuclear Information System (INIS)

    Cook, A.; Daulay, B.

    2000-01-01

    In this comprehensive article the authors describe the origins and progress of the Indonesian coal industry and the role it plays, and will play, in the domestic energy scene and world coal trade. In the '80s, the Indonesian coal industry laid the basis for major expansion such that coal production rose from under a million tonnes in 1983 to 10.6 million tonnes in 1990, 50.9 million tonnes by 1996 and 61.2 million tonnes in 1992. At the same time, exports have increased from 0.4 million tonnes to 44.8 million tonnes. Current export levels are higher than originally expected, due in part to a slow down in the construction of electric power stations and a partial switch to natural gas. This has slowed the rate at which domestic coal demand has built up. The majority of coals currently exported are low rank steam coals, but some of the higher rank and very low ash coals are used for blast furnace injection, and a very small proportion may even be used within coking blends, even though they have poor coking properties. The Indonesian coal industry has developed very rapidly over the last six years to become a significant exporter, especially within the ASEAN context. The resources base appears to be large enough to support further increases in production above those already planned. It is probable that resources and reserves can be increased above the current levels. It is likely that some reserves of high value coals can be found, but it is also probable that the majority of additions to reserves will be lower in rank (and therefore quality) compared with the average of coals currently being mined. Reserves of qualities suitable for export will support that industry for a considerable period of time. However, in the longer term, the emphasis of production will increasingly swing to the domestic market

    Presents data on China's coal industry. China's coal reserves are estimated to be 4,000 million Mt; annual production is over 800 Mt. Eleven new mining projects have been recently completed. They were financed with participation of foreign capital (US$ 1,400 million). Twenty-five new mines with 32.27 Mt production capacity were planned to be put into operation in 1988. Annual coal production is expected to increase to 870 Mt in 1990 at a cost of US$ 8,500 million. Numerical data on China's individual coal basins, new schemes, capital outlay and foreign capital participation are given. The dynamic development of China's coal industry since 1949 is briefly reviewed and management methods are explained.

    UK industrial coal sales were down 400,000t to 7.1mt in 1991. This was largely due to fall in cement purchases as the construction industry was badly hit in the recession. Increased competition from petroleum coke also had an effect. A brief roundup is presented of sales to the UK's major coal buyers: Alcan, ICI, Blue Circle, Castle Cement, Rugby Cement, British Steel, UK Paper, Courtaulds, Unilever, AHS Emstar, Tate Lyle, and British Sugar. 1 tab.

    In the German hard coal mining industry approximately since the 1970ies, automatically releasing stationary powder snow based fire fighting systems are built on diesel vehicles due to reasons of fire protection. These fire fighting systems are to recognize a developing fire by sensors and to extinguish the fire by an automatic output of a fire fighting agent with high rate (HRD = High Rate Discharge) into a closed engine compartment or within the range of hydraulics. Simultaneously with the releasing of the fire extinguishing system the engine of the vehicle is stop automatically. Due to the stationary fire fighting systems diesel vehicles are not classified with views of risk as fire load.

  2. Indian coal industry: Growth perspective

    International Nuclear Information System (INIS)

    Sachdev, R.K.

    1993-01-01

    Growth perspective of Indian coal industry and their environmental aspects, are discussed. The complete coal chain comprises of mining including preparation and processing, transport, usage and disposal of solid, liquid and gaseous wastes. Proper environmental protection measures are therefore, required to be integrated at every stage. At mining stage, land reclamation, restoration of surface damaged by subsidence and proper treatment of effluents are the minimum requirement for effective environmental protection. Since coal will continue to be the major source of commercial energy in coming decades initiative will have to be taken in making coal a clean fuel from the point of view of its usage in different industries. Washing of high ash coals for reducing the ash content will go a long way in reducing the atmospheric pollution through better plant performance and reduced environmental pollution at the power plants.

  5. German coal and the Ruhrkohle AG in an energy policy context

    International Nuclear Information System (INIS)

    Hessling, M.

    1993-01-01

    German coal output has fallen since 1957. The Ruhrkohle AG was established in 1968 to reorganise the mining industry in the Ruhr district. It comprised 52 collieries with 186000 employees. The number of collieries was reduced to 15 and the number of employees to 79000 by 1992. Output fell from 91 to 46 mill. t/a. A time frame was created by Coal Concept 2005. The contribution of German coal to energy supply has been reduced for financial policy reasons, but the mining industry has acquired long-term prospects. The required retrenchment is already extremely difficult to implement and handle according to the agreements of November 1991, but the current steel crisis has necessitated that the measures be brought forward.

    The United Mine Workers' Union claims that Australia is not getting enough for its coal. Moreover, coal company executives argue that the open market policy was failing the industry and that the export customers were manipulating Australian producers. Consequently, the unions are calling for Federal Government intervention and support the establishment of a national coal authority to co-ordinate the marketing of coal and investment in the industry. ills

    1998-01-01

    The Australian coal industry is actively involved in greenhouse gas emission management and abatement issues. An Australian Coal Association (ACA) position paper on greenhouse in November 1989, recommended a number of strategies to minimise the greenhouse effect, including the enhancement of energy utilisation efficiency, improved energy conversion efficiency at coal-fired power stations, expanded use of solar heating, and improved recycling. All of the strategies have been implemented to various degrees. The management and abatement of greenhouse gas emissions within the coal industry has been approached from an individual operational level, and a 'higher' industry level

    1988-09-01

    In the run up to the privatisation of the electricity supply industry in Scotland, the South of Scotland Electricity Board (SSEB) is involved in a battle for power with British Coal's Scottish area over the price of its coal, the bulk of which has been purchased by the SSEB in recent years. The SSEB has been trying to persuade British Coal to bring its prices down to those currently available on the world market. This would require a reduction of some 30%. The SSEB has backed up its requests by threatening to import more foreign coal if British Coal refuses to comply.

    1992-01-01

    Corporate ownership within the German nuclear industry has evolved constantly during the last decade, and recent acquisitions and mergers, reunification of the country, as well as preparation for a unified European power market, have led to many significant changes during the past two years. The country's nuclear industry continues to struggle under an increasingly anti-nuclear political environment, yet nuclear power provided more than one-third of Germany's total electricity generation in 1991. As in many countries, particularly in western Europe, many German companies involved in different facets of the nuclear industry are interrelated. Usually as a means of horizontal or vertical integration, the country's nuclear utilities own, directly or indirectly, shares in uranium mining projects; conversion, enrichment, and fabrication companies; or other utilities' nuclear power plants. The utilities own partial interests in companies in supporting industries as well, including transportation firms, waste management companies, uranium broker/traders, and nuclear equipment manufacturers. While the majority of the companies owned are German, numerous investments are made in non-German firms also

  12. Coal industry statistics for 1977

    1978-01-01

    In 1977 Belgian coal production reached 7,068,000 t, a drop of 170,000 t (2.3%) on the previous year. Production from the Campine coalfield had risen by 160,000 t while in the South, where two pits had been shut down during the year, there was a fall in output of 330,000 t. On 31st December 1977 the number of underground personnel totalled 17,681 as against 19,154 at the same time in 1976. Underground output continued to decline in the South while in the Campine there was an increase of 7.6%. Pit-head stocks fell by 400,000 t, to 721,000 t, 658,000 t of this being held in the Campine collieries. As regards Belgian coal disposals, the only increase (+52.0%) was in coal sent to power stations. Import figures stood at 6,592,000 t, a drop of 10.5% over the previous year. Includes figures for apparent coal consumption, a com parison of coal figures for 1976 and 1977 and the mined-coal production. Shows how coal production has evolved in the various coalfields and the number of pits in operation. Production is classified into coal types. Also covers the shutting-down of production capacities; manpower and OMS; coal briquette production; briquette output and disposals; end-of-year pit-head stocks according to coalfields, grades and types of coal.

  13. Environmental problems in Russian coal industry

    International Nuclear Information System (INIS)

    Kharchenko, V.; Oumnov, V.

    1996-01-01

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

    1984-01-01

    Presidential Address by Sir Norman Siddall is presented which considers the problems and prospects facing the UK coal industry. The range of changes which business management is subject to are outlined together with the coal industry's response to these changes. Fluctuations in the energy market and the economy have resulted in a customer orientated approach to marketing, and improved efficiency throughout the industry. New technology has increased the efficiency of some aspects of operations but at the some time developments in the areas of industrial relations and public accountability have limited management's ability to respond to changes in the commercial environment.

  15. Coal: the metamorphosis of an industry

    Jean-Marie Martin-Amouroux

    2008-07-01

    Coal, a fuel that once dominated the global energy scene, is staging a come-back despite being environmentally dirty. The purpose of the paper is to analyse the return of King Coal to find out whether it is likely to be regain its dominance in the global energy in the future. In analysing the metamorphosis of the coal industry, the paper looks at the historical evolution of the industry and analyses the factors behind the change. The deficiencies of coal's competitors are also analysed. Using a scenario analysis, the future role of coal in the global energy mix is estimated as well. The paper finds that despite the domination of hydrocarbons in the global energy mix, coal has maintained a steady share and in some countries, it remained the main fuel. With the concerns of high-oil prices and peak oil, coal is regaining its domination in the power sector around the world. The industry has reformed and restructured itself to remain competitive. Consequently, it has the possibility of staging a come back as a dominant fuel.

  16. The restructuring of the international coal industry

    The international coal industry is now becoming a global industry emerging from a history of production for national purposes and isolated regional markets. The participants in the market are also changing; the oil companies have come and gone and production is now in the hands of specialist mining companies. This has implications for the way the industry is organized. Deregulation in the electricity market means that coal mining companies face the challenge of entering into the new millennium in a more competitive market but companies may also have the opportunity to differentiate their product through risk management.

    Problems encountered in the expansion of the USA export market for coal are discussed, including: lack of port facilities to handle bulk coal shipments; inadequate rail facilities and the already high costs; and delays caused by complex legislation. Solutions to the problem of ports are suggested, and also the advantages of coal export expansion with respect to industry as a whole and unemployment. Details of projects on the Canton Railroad and the terminal in Baltimore are given. Views of the American Association of Port Authorities on navigation are expressed.

  18. Accelerated adjustment in the German hardcoal industry

    1994-01-01

    The worsening overall economic situation and the steel crisis necessitate an accelerated adjustment of the production capacity and the output. In 1993 hardcoal production was reduced by almost 8 Mtce or 12% to some 59 Mtce. The coke production of the colliery-owned coke oven plants was even reduced by 27%. Following the strong decline of deliveries in 1992 (-6 Mt), the sale of hardcoal and coke fell by another 4 Mt to about 60 Mtce in 1993. The high sales losses resulted in a further increase in stock. At the end of 1993 23 Mt coal had been stockpiled and burdened the results and liquidity of the hardcoal mining companies. The loss of jobs is aggravating. At the end of 1993 the hardcoal industry employed a workforce of 113500, of those 106300 own employees and 7300 workers form contractors. In the course of the year 10600 jobs were lost totaling up to about 55000 since the 1987 coal round. With an underground OMS of 5267 kg the hardcoal industry has reached the highest productivity level so far. In 1994 the hardcoal industry will continue to contract. The hardcoal output is to be reduced to less than 53 Mtce to achieve a reduction of stock in the mining companies. (orig.)

    The Green Paper, 'Energy Policy - a Consultative Document' (HC-Cmnd--7101) affords a valuable insight into official attitudes towards the future of the British energy market. The present author challenges some of the energy supply and demand forecasts that are presented in the Working Document; in particular, he questions the optimistic market forecasts that continue to dominate official thinking about the coal industry; and he proposes that an alternative strategy is required for the British coal industry, one that involves quite painful choices of an economic, geographical, social and environmental nature.

    The use of nuclear techniques for the determination of important parameters in industrial installations is exemplified; advantages of these techniques over other methods conventionally used are pointed out. The use of radiotracers in the study of physical and chemical phenomena occurring in the chemical industry is discussed. It is also shown that, using certain radioisotopes, it is possible to construct devices which enable, for example, the determination of the ash content in coal samples. These devices are economical and easy to be installed for the on-line control during coal transportation. (C.L.B.) [pt

    The difficulties of the reconstruction era, following World War I had been increased by the cessation of some activities in the industrial centres of the Banat Highland. For instance, the copper mines were closed in 1921, the Romanian state forbidding the extraction of this ore. Only in Ocna de Fier a special dispensation had been given. The copper mines from Moldova Nouă, Sasca Montană, Ciclova, Dognecea had also been shut down. This fact caused the acid reaction of some writers. We recall that one of the main ways for improving the material condition, embraced by the ethnic Germans, was working abroad. Many German workers of the Banat Highland had emigrated, taking up an offer of well-paid work during the crisis years: 1929-1933. The miners of the Banat Highland, especially those of German origin, travelled to the areas rich in iron ore and coal of France, namely Alsace and Loraine. Considering that German was spoken there by a significant percentage of the population, the integration into the new working environment did not represent a problem.

    If the sustained growth in world demand for solid fuel continued, will offer follow? The new coal geography map that is in place since the 1973-1979 oil crises prompts one to answer in the affirmative. In the United States, China, Australia, South Africa, Columbia, Indonesia or Russia alike, the use of capital from steel, oil, electrical and other industries (via the banking system) has cause deep reorganizations. Forced to adjust to the price decrease on highly competitive markets, companies have changed their production methods (opencast, big size) to increase work productivity and reduce production costs. To do so, they banked on industrial concentration and caused a new coal industry to emerge. The latter seems prepared, through its direct investments or those that it raises (rail and maritime industry) to meet demands. (author)

  4. Privatisation of the British coal industry

    Cowles, R.V. (Norton Rose, London (UK))

    1991-01-01

    The article discusses the possible consequences of the impending privatisation of British Coal. It seems likely that deep mine operations will probably be divided up geographically but opencast mines may be left in single ownership. Freehold ownership of coal is likely to be transferred to the Crown and British Coal's powers to license small mines and opencast sites are likely to be absorbed into a general licensing system under control of the Department of Energy. Possible difficulties of public share issues are discussed - subsidence, environmental problems and also the uncertainty of the future market for British coal are mentioned. As an alternative, a series of contract sales of groups of mine properties could be made. Issues of common concern to future owners of the coal industry may lead to the creation of a new mineowner's trade association. Constraints in the areas of procurement and coal sales are discusssed briefly. Although a gloomy scenario is presented, it is suggested that some mines could become highly profitable. 1 ref.

    Full Text Available In march 1998 at the conference „Coal Utilization & Fuel Systems“ in Clearwater, USA representatives of U.S. Department of Energy presented the vision 21 focused on the electricity generation from coal for 21st century. The goal is a powerplant with the ability to produce the electricity from coal with the efficiency approaching 60% (higher heating value and emission levels of one-tenth of today´s technologies, The CO2 capture and permanent sequestration at the cost of $15/ton of CO2, and a cost of electricity of 3 cents per kilowatt-hour. The goal is believed to be achievable by the first quarter of the next century. The vision 21 is presented with several possible concepts. One of them is based on coal gasification with following hydrogen separation. The obtained hydrogen is used as a fuel for the cogeneration unit with fuel cells. The remaining gas can be liquefied and utilised as a fuel in the automotive industry or further chemically processed. The concept has several important features. Firstly, a very clean low cost electricity production. Secondly, it is comprised of fuel processing section and power processing section. The two sections need not to be co-located. In the world of the deregulated electricity generation this offers a major advantage. The technologies of fuel processing section – coal gasification and hydrogen separation have been successfully developed in the last two decades. A specificity of the fuel processing section of this concept is to obtain hydrogen rich gas with very low concentrations of substances, as CO, which cause a poisoning of electrodes of fuel cells leading to the decreasing fuel cells efficiency. Fuel cells, specially highly efficient coal-gas SOFC and MCFC, are expected to be commercially available by 2020. The natural-gas MCFC and SOFC plants should enter the commercial marketplace by the year 2002.

    Although China owns large coal reserves, it now faces the problem of depletion of its coal resources in advance. The coal-based energy mix in China will not change in the short term, and a means of delaying the coal resources depletion is therefore urgently required. The residual coal was exploited first with a lower recovery percentage and was evaluated as commercially valuable damaged coal. This approach is in comparison to past evaluations when the residual coal was allocated as exploitation losses. Coal recovery rates, the calculation method of residual coal reserves and statistics of its mines in China were given. On this basis, a discussion concerning the impacts on the delay of China's coal depletion, development of coal exploitation and sustainable developments, as well as technologies and relevant policies, were presented. It is considered that the exploitation of residual coal can effectively delay China's coal depletion, inhibit the construction of new mines, redress the imbalance between supply and demand of coal in eastern China, improve the mining area environment and guarantee social stability. The Chinese government supports the exploitation technologies of residual coal. Hence, exploiting residual coal is of considerable importance in sustainable development of the coal industry in China. - Highlights: •Pay attention to residual coal under changing energy-mix environment in China. •Estimate residual coal reserves and investigate its exploitation mines. •Discuss impacts of residual coal exploitation on delay of coal depletion in China. •Discuss impacts on coal mining industry and residual coal exploitation technology. •Give corresponding policy prescriptions.

    Minister of the Soviet coal industry evaluates social and economic development plan of the Soviet coal industry from 1981 to 1985. Planned coal production should increase to 770-800 Mt, exceeding coal production in 1980 by 53 to 83 Mt. Proportion of coal mined by surface methods will further increase. Investment program concentrates on: construction of the Kansk-Achinsk fuel and energy basin, construction of the South Yakut coal basin and further development of surface mines in the Ehkibastuz basin. Proportion of coal mined in the Kuzbass will increase to 45% of the total coal output. Construction of the Kansk-Achinsk basin has the highest priority among the investment projects. Investment projects (construction of new coal mines and modernization of existing mines) in major coal basins in 1981 are analyzed. Mining machines and equipment for underground and surface black and brown coal mining are evaluated. Plans for developing new mining systems are described (e.g. narrow web coal cutter with chainless haulage system for thin and medium coal seams with drive system with power ranging from 110 to 315 kW). The following types of machines are discussed: coal cutters, shearer loaders, heading machines, belt conveyors, loaders. Selected social problems associated with manpower shortages for underground mining and for coal mines operating under extreme climatic conditions are also discussed.

    Industry observers currently peg the share of 'spot' contracts in Australia's black coal export market (valued at $9 billion a year) at 15%, compared with only 5% of market share four years ago. This quantum shift in purchasing habits is being driven largely by abundant coal supplies, a multi-source availability of coal, and falling prices - a scenario that is expected to remain unchanged for at least the next three to five years. Contracts are not only becoming shorter, they are also dealing with lower tonnages. And, unlike under older long term contracts, where prices are reset every one to two years, under the modern versions prices are being reset every three to six months. As buyers push to achieve more competitive pricing outcomes and maximise the supply of competitively priced fuel, this forces everyone associated with operating power plants to look for ways to reduce costs and implement higher levels of efficiency, by saving time and paperwork. Net-based trading in coal is happening. The major buyers and sellers operate most of the existing sites. Buyers see the Net as a means of reducing the cost of their fuel; sellers see it as a means of better displaying the product they offer. The use of the Net is seen as providing improved market intelligence, greater transparency, better marketing and service levels and enhanced efficiencies. The one-to-one approach remains a fixture and its future is assured. However, whether the Net will ultimately support independent trading sites similar to those whose income will come from brokering deals is hard to judge.

    2017-01-01

    Contributing to approximately two-thirds of primary energy consumption, coal usage is the focus of China's energy policies. To regulate the resource taxation system and reduce the burden of coal enterprises, the Chinese government launched a reform of its resource tax system in 2014 for coal, introducing the ad valorem system to replace the volume-based system that had been in place for the preceding thirty years. To assess the impact of the tax reform, this paper constructs two-stage dynamic game models by taking the coal and coal-fired power industries as the players. The market situations of shortage and oversupply are investigated separately. Empirical data are collected to estimate the model parameters for numerical simulations. The model results suggest that the tax reform will reduce both coal prices and the coal industry profitability if the tax levied on each ton of coal is maintained at the same level as before the reform, regardless of whether the market is in a shortage or an oversupply situation. However, the increased buyer's power will amplify the effect of the tax reform. The numerical simulations also provide an estimation of the tax rate of the ad valorem system that maintains the profit of the coal industry. Considering the demand and supply situations in China's coal market, policy recommendations are provided to guide further reform of China's resource tax system. - Highlights: • The paper examines the influence of resource tax reform on China's coal industry. • We construct two-stage game models between coal and coal-fired power industries. • Market situations of shortage and oversupply are studied in two taxation systems. • Coal price will decrease if maintaining the tax levied on each ton of coal the same. • To achieve the reform objective, the ad valorem tax rate should not be set too high.

    China's coal and electricity industries have a strong reliance on each other, however, because of excessive invasion of government, it is difficult for these two industries to form a stable, reasonable, and transaction cost-saving relationships, but long-run disputes and quarrels. This paper discusses the pricing policies and transaction relationship between these two industries from the historical perspective. It begins with the discussion of coal. Coal market has become competitive since 1980 due to the system of dual track approach, but coal sold to electricity was still tightly controlled by government-guided pricing. Then the paper examines electricity investment and tariff reform. Unlike coal, entry to electricity generation sector was gradually relaxed but generation and retailing tariffs are still strictly regulated. As energy demand and prices soared after 2002, coal and electricity enterprises are all unsatisfied with the rule of price setting of coal sold to electricity industry. This paper concludes that the deliberate low coal price policy does protect electricity industry from fuel cost fluctuation but harm coal industry. Allocative and productive efficiency are difficult to achieve in the long run

    Since energy has constituted itself a bottleneck in the economic development in China, the development of energy has long become an important element of the country's policies on the industry. Policies and credit operations of the state development bank in support of coal development in China are discussed. To support the coal industrial growth of the country, the State Development Bank has been engaging itself in the coal credit operations. At present in China, 90 % of the funds for the large and medium-sized coal projects are loans from the state banks with the rest 10 % being foreign investment. Actions to attract more foreign investment for China are discussed. (R.P.)

    The demand for energy has been increasing over the years especially with the country's accelerated economic growth as we move closer its vision of industrialization by the turn of the century. Pursuant to this, the Department of Energy (DOE) was mandated to ensure the country's energy supply availability at affordable costs with due consideration to environmental concerns. Likewise, our organization, the Philippine Chamber of Coal Mines, Inc. (PHILCOAL), an association of local coal producers has taken the role of continuing its task of promoting the development and growth of the coal industry and to cooperate with the governmental agencies in their program of accelerating the development; growth and stability of the energy's coal sector. This paper will present a brief overview of the current situation of the coal industry, citing among others the country's coal reserves, quality, the industry's performance and the coal supply and demand projected for a five-year period. This paper shall also briefly discuss the government's plan to intensify coal exploration efforts so as to ensure the expansion of the country's production capabilities, the establishment of more terminals and infrastructures and accelerate the implementation of mine-mouth power generation and co-regeneration projects in potential coal areas. The implementation of the government's plan for the coal sector will require substantial capital and this paper will cite the principal areas where local and foreign project can come in. Finally this paper conclusively state that the country will remain a net importer of coal on account of the inability of local coal producers to meet increasing rate and coal demand. (author)

    2012-07-01

    The author analyses the decision to abandon the co called ''review clause'' (which was the right to revisit the decision to close German hard coal mines in 2012), and thus management flexibility on the basis of the option price theory and use of hedging instruments (derivatives) in coal trading. Only the case of coal production without any subsidies will be taken into account. The original intention of the review clause to subsidise coal production for further years will be left aside. Abandonment of the review clause destroyed a value of the real option of approx. 819 Mio. EUR. It should be agreed with the politicians that the decision concerning potential extension of coal production without subsidies should be made at the end of 2015. At this point in time the coal price for 2019 to 2021 can be locked in by forward contracts. A prerequisite for coal mining without subsidies would be an increase in the coal price of 3.1% p.a., which is only slightly above the inflation rate and seems to be realistic against the background of rising oil prices and increased scarcity of natural resources.

    The author analyzes the decision to abandon the revision clause, i.e. to abandon entrepreneurial flexibility on the basis of the option price theory and the use of derivatives in coal trading. The focus is on subventionless continuation of coal mining. It is found that the abandoning of the revision clause will involve a loss of value of the real option of about 819 million Euros. Politicians and the coal industry are advised to revise the subventionless continuation of coal mining by the end of 2015.

    The U.S. coal industry is stable and efficient, and in good position to respond to any increase in export demand over the next ten years. After the 1973 and 1978--79 oil price increases and the resulting growth in world demand for coal, the industry responded with extensive investment in coal mines; the transportation industry similarly made large investments in coal handling equipment and port facilities. However, as a result of the expansion in world production facilities and the less than anticipated growth in coal demand, the United States now has excess capacity---in the mining, transport and port terminal industries. The coal industry's large capital investments, followed by cost cutting improvements in response to excess capacity, have paid off in greatly increased productivity. Between its low point in 1978, and 1985, average tons per miner-hour grew by 55 percent, or at an average annual rate of 6.4 percent. This gain has been passed on to coal customers in the form of lower prices. Between 1976 and 1985, FOB mine prices in constant dollars declined by 26.9 percent, or at a rate of 3.4 percent per year; the trend continued in 1986 with an additional 4.8 percent price decline

    China is rich in coal resource, which is vital for energy security in this country. In early 21st century, the coal chemical industry in China will be oriented to the development of high efficiency, safety, cleanliness, and optimum utilization. In this review, the authors present an introduction to the utilization status of primary energy production and consumption in China. Since 2005, fundamental research studies, supported by the Ministry of Science and Technology of Chinese National Basic Research Program, have been carried out at Taiyuan University of Technology. The Ministry stresses that the new coal chemical industry should be developed in a sustainable manner to realize effective utilization of energy. Moreover, upgrading the high technology to improve actively the recycling processes of coal chemical engineering is of strategic importance to realize the modern coal chemical engineering.

  12. A newer concept of setting up coal refineries in coal utilising industries through environmentally sound clean coal technology of organosuper refining of coals

    1994-01-01

    In order to reduce the losses of premium organic matter of coal and its immense potential energy which is present in the form of stronger interatomic and intramolecular bonding energies, a newer and convenient technique of recovering the premium organic matter from low grade coals by organosuper-refining technique which operates under ambient pressure conditions has been developed. The residual coal obtained can be used as environmentally clean fuel or as a feedstock for the industries based on carbonization and gasification. It is suggested that a beginning be made by setting up coal refineries in coal utilizing industries on the basis of the presently developed new technology of organosuper-refining of coals to recover premium grade organic chemical feed stocks from coals before utilizing coal by techniques such as bubble bed or recirculatory fluidized bed or pulverized coal combustion in thermal power stations, carbonization in steel plants or other carbonization units, gasification in fertilizer industries or in integrated coal gasification combined cycle power generation. Thus, coal refineries may produce value added aromatic chemical feed stocks, formed coke or coke manufacturing; and carbon fillers for polymers. (author). 100 refs., 1 fig

    2016-01-01

    The German Energiewende, or energy transition, is an ambitious suite of policy measures which aim to decarbonize the German economy and achieve an almost complete transition to an energy system based on renewable energy by mid-century. This article contends that the energy transition is also a social process. We develop a provisional local ethnography of the Energiewende, an account of the lived experience of this social process from the perspective of villagers in Atterwasch, Kerkwitz and Grabko, in the region of Lusatia in Eastern Germany. Their experiences are particularly salient, since their villages are facing demolition to make way for the expansion of the nearby Jänschwalde coal mine. The villagers’ struggle to defend their homes highlights a fundamental contradiction in the energy transition, sometimes referred to as the “coal conundrum”. The contest over the future of coal in Lusatia can be seen as a struggle to control key cultural ‘scripts’ or narratives, of home, belonging, ecological modernization, climate change, and democratic deficit. Our research suggests that any resolution of the coal conundrum, and effective implementation of the Energiewende, must be informed by an understanding of these scripts, and how they underpin the motivations and mentalities of different social actors. - Highlights: • The German energy transition is a social process as well as a set of policy measures. • Lusatia, in Eastern Germany, is a social laboratory of the Energiewende. • The contestation of coal in Lusatia is a struggle to control cultural ‘scripts'. • Home and belonging, ecological modernization, and climate change are key scripts. • More “energy democracy” would bolster the legitimacy of the energy transition.

    The rapid development of coal industry in Shanxi province in China has important effects on its economic development. A large amount of money has been invested into the coal industry and other related industries during the recent years. However, research on the investment effect of Shanxi's coal industry was rare. In order to analyze the investment effect of coal industry, based on the crowding-out effect model, cointegration test, and the data available in Shanxi Statistical Yearbooks, this paper calculates the effect between coal industry investment and other 17 industry investment. The results show that the investment of coal industry produces crowding-out effect on food industry, building materials industry, and machinery industry. Increasing 1% of the coal industry investment can reduce 0.25% of the food industry investment, or 0.6% of building materials industry investment, or 0.52% of the machinery industry investment, which implies that Shanxi province should adjust coal industrial structure, promote the balance development of coal industry and other industries, so as to promote its economic growth.

    Poland's accession to the European Union has reduced the remnants of import barriers. Moreover, the consolidation and commercialization of the energy sector, the implementation of climate package elements and a whole host of other determinants have caused hard coal mining to begin functioning in a highly competitive market, and its negotiating position, as well as the possibility of survival, depends not only on the level of coal prices in international markets, but also on internal competition. This paper discusses the position of power coal on international markets and presents some current problems concerning the functioning of particular segments of the hard coal market in the European Union and Poland in terms of opportunities and threats that are a result of climate and energy policy.

    Coal world production represents 3.5 billions of tons, plus 900 millions of tons of lignite. 50% of coal is used for power generation, 16% by steel making industry, 5% by cement plants, and 29% for space heating and by other industries like carbo-chemistry. Coal reserves are enormous, about 1000 billions of tons (i.e. 250 years of consumption with the present day rate) but their exploitation will be in competition with less costly and less polluting energy sources. This documents treats of all aspects of coal: origin, composition, calorific value, classification, resources, reserves, production, international trade, sectoral consumption, cost, retail price, safety aspects of coal mining, environmental impacts (solid and gaseous effluents), different technologies of coal-fired power plants and their relative efficiency, alternative solutions for the recovery of coal energy (fuel cells, liquefaction).

    1985-04-25

    Efforts to keep China's coal industry financially healthy and to continue increasing production also created problems in terms of output, transport, environmental damage, accidents, and labor pressures. In addition to the historical and economic reasons for these pressures, inadequate leadership and policy errors made things worse. An analysis suggests three problems: (1) an inequitable division of duties between government and business, (2) a neglected marketplace, and (3) the dominance of egalitarianism. The report relates these problems to the production of coal and a package of reforms which restructured the economic system of the industry to give it more autonomy and economic responsibility. The reforms emphasize rational pricing and use of coal as well as management of the industry.

    The European Commission has told the German federal government to open the door for coal imports from other EC member countries. As an initial step, the Commission is suggesting that some of the power station coal which was to be sourced from German stockpiles under the November 1991 agreement between Rurhkohle AG, the state mining company and the generators, be supplied by other member states such as the UK. The implications of this move for the German coal industry are discussed. 2 tabs.

    South Africa is a significant contributor to southern Africa and Europe's coal needs and is expected to remain in this important position for the foreseeable future. This review paper of the South African coal mining industry highlights that, although abundant, the easily mineable reserves will become depleted within the next quarter century. Socio-economic issues of unique, local importance such as the HIV/AIDS pandemic as well as policies propagated by South Africa's post-apartheid government are detailed, as are programmes in research and development that will ensure that South Africa's long term coal industry is, at the every least, maintained. 11 refs., 9 figs., 7 tabs.

    Kobe Steel's (Kobelco) corporate strategy includes expanding from only-one product such as high tensile strength steel sheet, and enlarging overseas production capacity through joint ventures and technical alliances. A new steel making process from low quality iron ore and steaming coal called ITmk3 has been developed by Kobe Steel that does not require any coke, reduces carbon dioxide emissions by 20 per cent, and reduces the cost of transporting slag. This strategy and technology was presented along with the changes surrounding the Japanese steel industry and raw materials market. These changes include the rise of emerging oil-producing countries; world steel production and exports; the rise in prices of resources; and the slowdown of the United States economy. The current situation of Japanese crude steel production, pig-iron production, and coke expansion plans were also presented. The presentation also outlined expectation's of the Canadian coal industry with reference to Canadian coal imports to Japan. tabs., figs

    1998-07-01

    Industry pundits predict that coal by wire may some day replace much of the industry`s long-distance shipping requirements and their attendant costs, but data by wire, also known as electronic commerce (EC) can today offer coal producers and customers the means to gather and send large volumes of data cheaply and quickly. EC`s major components - electronic data interchange (EDI), bar-coding, smart codes, radio frequency `D`, and the internet - can reduce costs in equipment-intensive industries such as mining. The US National Mining Association sponsored a forum to discuss these alternatives at its 1998 Electronic Commerce Summit held in Tuscon, Arizona, 18-20 May. A report is given of discussions at the forum and contacts are given for sources of EDI information.

    Japan's crude steel production exceeded 100 million tons for the first time in fiscal 1972 and reached a peak of 120 million tons in fiscal 1973, as shown in this paper. The Japanese steel industry then switched from quantity to quality in line with production and market trends in the world. In fiscal 1987, all steelmakers announced future plans for reductions in steel production facilities on the assumption that Japan's crude steel production would hover around 90 million tons in response to the change in the country's production structure. Although steel production has held strong with the expansion in domestic steel demand triggered by the government's economic policy and the production plans that have eventually put their original production plans into practice. In its energy-saving activities prompted by 2 oil rises, the Japanese steel industry has dramatically improved its energy costs through energy conservation, waste heat recovery and process step consolidation, as represented by the reductions in blast furnace fuel rate and coke-oven heat consumption. During this period, the Japanese steel industry has won independence from oil and increased dependence on coal. This paper describes coal utilization technologies in coke ovens and blast furnaces, 2 major coal consuming processes in the steel industry. The environmental problems associated with the use of coal are discussed as well

    The use of coal, hard coal and lignite, is compatible with the targets of the German ''Energiewende''. This fact is often ignored. Due to the uncertain geopolitical situation, the domestic lignite is an important element for a reliable energy supply of Germany. In addition to the known factors secure availability, competitiveness and local economic importance, flexibility has become a characteristics of lignite. The change of the German energy supply is only possible with domestic lignite. This article points out the importance of lignite for this process.

    2013-01-01

    Based on China's basic national energy conditions of “abundant coal and scarce gas reserve”, the development of the coal based SNG industry is considered to be an effective way to solve the conflict between the supply and demand of natural gas and an important direction in the clean use of coal. Xinjiang is rich in coal resources and is listed by the central government as one of the main bases of the coal based SNG industry. Nearly 70% of the coal based SNG projects are being conducted in Xinjiang, with the goal to take advantage of the lower coal price in Xinjiang to promote the development of the coal based SNG industry. However, the coal based SNG industry is subject to the constraints of pollution, immature technology, poor economic returns, water resources and many other factors. Therefore, the development of the coal based SNG industry should be limited to industrial demonstration. Taking into account China's energy security and environmental governance, once the technology matures, the development prospect of the coal based SNG industry is broad. - Highlights: • Booming in the coal based SNG is not oriented to market, but investment-driven. • Coal based SNG is restricted by pollution, technology, economic and water resources. • The positioning of coal based SNG industry should be industrial demonstration. • The immature technique is the biggest obstacle

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

    The Ruhr coal industry will reduce its production capacity beyond the initial target due to the unexpected dramatic decline in coking coal sales. In a move of joint social responsibility the collective bargaining parties therefore entered their negotiations prematurily, in December 1993, in order to agree on additional - temporary - free shifts subject to salary deduction, in an attempt to master the added burden of adaptation and avoid dismissals. On December 20, 1993, then was concluded a collective agreement which takes due account of that target. (orig.)

    The historian Fernand Braudel considered that geography dictates history because a certain region or a certain state requires a characteristic of its economic life. Commerce was often called in mercantilist period the blood that provides life of the nation. These data imply progress in terms of demographic beyond doubt, especially in the employment of the German minority living in the urban communes of the Banat Mountain. We retain the dual nature of their occupations, with farm work kept in the background, but the main plane dominated the gradual effect of industrial labour and business activities. Along with farmers, most Germans residing in villages and hamlets in the mountains of Banat were devoted to jobs in the service sector and small crafts area. They worked both as employers and employees in the stores and workshops in rural and urban areas where they resided. Working as sellers, barbers, blacksmiths, carpenters, tailors, butchers, tanners, plumbers, painters or as doctors, dentists, teachers, lawyers, they have contributed to the development of material and spiritual not only their own minority but of communities within which they were born and prospered.

  15. Development trends in the Lusatian brown coal mining industry

    International Nuclear Information System (INIS)

    Schwirten, D.

    1994-01-01

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

  16. Industrial Pastoral: Lake Macquarie Coal Miners’ Holidays

    Russell McDougall

    2010-11-01

    Full Text Available As Stephen Page and Joanne Connell note in their mapping of the field, leisure studies is a largely post-war development, evolving internationally out of geography, economics, sociology and a range of other disciplines mostly in the social sciences rather than the humanities. Historians have not ignored the subject – there are plenty of historical studies of sports and recreation, the development of national parks, and so on. Yet, while leisure clearly has a vital and dynamic relation to work – culturally, politically, psychologically – labour historians in Australia appear to have been less interested in this area of research. We, the authors of this article, are primarily literary scholars rather than historians, but we have been puzzled by this apparent neglect. It is not our brief to examine the contemporary meanings of ‘leisure’ in relation to ‘work’ (or ‘forced labour,’ to adopt Guy Standing’s important twenty-first century distinction. Instead, our own study of coal miners’ holidays around Lake Macquarie from the late nineteenth and into the second half of the twentieth century considers the bygone rituals and activities of their holidaying from the vantage point of our own present location in an age where ‘simulation and nostalgia lie at the heart of everyday life.’ The article includes memoir and creative writing along with theory and analysis.

  17. The German model of capitalism and the persistence of outward foreign direct investment: evidence from German manufacturing industries

    Directory of Open Access Journals (Sweden)

    Martin T Bohl

    2011-06-01

    Full Text Available Against the backdrop of critique on the German model of capitalism in general, and German public policy in particular as to the ability to successfully adjust to rapid change and exogenous shocks in wake of economic globalisation, this paper investigates the degree of shock persistence in foreign direct investment (FDI of ten German manufacturing industries for the period 1976 to 2003. Theory on exports and non-FDI investment suggests that FDI should exhibit a considerable degree of shock persistence because they are subject to high sunk costs because of high entry and exit costs associated with the high level of asset specificity that is normally connected to FDI. Persistence in foreign direct investment time series data is established by applying various unit root tests. The results are robust to the potential presence of structural breaks in the data. The empirical analysis shows that German outward FDI in mature manufacturing industries, with one exception, exhibits a high degree of shock persistence. The results suggest, at least for mature German industries, that the sunk costs view on shock persistency is confirmed for outward FDI. The results furnish evidence for a tentative assessment of the relationship between German public policy and FDI strategies of multinational firms.

    In this paper, an outline of and the R & D agenda for the Indian coal industry, highlighting the national priorities, is suggested. To prepare a viable R & D activity for the coal industry it is necessary to examine, through a priority analysis, the attractiveness and feasibility of research areas which could make significant contributions to the future of Indian coal industry. While meaningful measures per se are difficult to identify, the following criteria may form the basis of such a screening procedure: (1)level of maturity of the existing technology; (2) cost-benefit ratio of R & D; (3) impact on productivity due to incremental changes arising from R & D efforts; and (4) technological maturity of the industry to apply, adopt or adapt the results of R & D. In assessing the overall objectives of any specific portfolio of R & D projects, the costs, time-frame, and benefits will be the prime determinants of the attractiveness. It is necessary to consider both the potential beneficial impacts of a successful R & D programme and also the probability of success within a reasonable time-frame.

    Bush, W. A.; Slade, E. C.

    1978-06-01

    A survey of the industrial capabilities of the valve and valve-actuator industry to supply large, high-pressure stop valves for the future coal conversion industry is presented in this report. Also discussed are development and testing capabilities of valve and valve-actuator manufacturers and anticipated lead times required to manufacture advanced design valves for the most stringent service applications. Results indicate that the valve and valve-actuator industry is capable of manufacturing in quantity equipment of the size and for the pressure and temperature ranges which would be required in the coal conversion industry. Valve manufacturers do not, however, have sufficient product application experience to predict the continuing functional ability of valves used for lock-hopper feeders, slurry feeders, and slag-char letdown service. Developmental and testing efforts to modify existing valve designs or to develop new valve concepts for these applications were estimated to range from 1 to 6 years. A testing facility to simulate actuation of critical valves under service conditions would be beneficial.

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

    The petrologic, chemical and technological features of low-rank coals from nineteen of the most important basins in Serbia have been studied as part of the research project of genetic-industrial classification of low-rank coals of Serbia. Most of these features have been included as parameters of the codification system for low-rank coals. The paper discusses the main genetic, technological and supplementary parameters of the Serbian brown coals such as rank, petrographic composition, gelification degree, total moisture, ash content, sulphur content, calorific value, tar yield, the chemical composition and the thermotechnical properties of ash. The rank of brown coals from Serbia has been defined on the basis of the following parameters: random reflectance of huminite/vitrinite (R{sub r}=0.26-0.50%), total moisture (W{sup ar}=13.18-49.11%), gross calorific value (Q{sup daf}=22.3-29.2MJ/kg, dry, ash-free basis), net calorific value (Q{sup daf}=21.2-28.1MJ/kg, dry, ash-free basis). The results from the maceral analysis confirm that the humic coals, in general, are characterized by high huminite content (76.0-97.9vol.%, mineral matter free), low inertinite amount (0.7-6.3vol.%, mineral matter free), and a variable amount of liptinite (0.8-15.5vol.%, mineral matter free). It is possible to define three groups of Serbian brown coals on the basis of the primary, or genetic parameters, technological, or chemical parameters, and supplementary parameters: soft (Low-Rank C; [Economic Commission for Europe, Committee on Sustainable Energy- United Nations (ECE-UN), 1998.

    Reduced operating costs, lower greenhouse gas emissions and security of supply are being cited by North Queensland industry leaders as the reasons for investing more than A$550 million to expand operations and convert to coal seam gas as their preferred fuel source. The article, by Enertrade, reports that just a few months after commissioning its North Queensland Gas Pipeline to transport coal seam gas from Moranbah to Townsville, Enertrade has signed contracts that will see combined cycle gas-fired baseload electricity generated in Townsville and the Queensland Nickel Refinery, and Xstrata Copper Refinery switch from liquid fuels to gas. The development has been driven by state government policy that 13% of Queensland's electricity be sourced from gas-fired power generation from 1 January 2005.

  11. Major energy users and reforms of the German energy industry

    Energy Technology Data Exchange (ETDEWEB)

    1994-06-01

    There is a historic tradition of industrial autoproduction of electricity in Germany. Major energy users in the past used to be and today often still are autoproducers of electric power. The public utility sector, according to present legal standards, operates in a framework that protects local and regional monopolies. The large consumers and autoproducers are an important countervailing power in the whole system of the electricity supply industry. Electric utilities (EU) in Germany are semi-public or private enterprises of a wide variety of size. The large producer utilities operate the high voltage grid on the basis of private contracts. Regional distribution companies mostly without a considerable share in production often in cooperation with local distributors deliver electricity (el) in the non-urban areas whereas mostly city owned EU supply the large cities often on the basis of considerable parts of autoproduction and often also with a considerable share of el produced in cogeneration plants. The equilibrium between the parts of this system in the past was ensured by a legal framework protecting local monopolies as well as long term contracts between producers and distributors. Deregulation trends inherent in European legislation on competition have threatened this stability. In the first phase resistance against a more competitive order seemed unanimous. In the meantime however the different actors had time to rethink their position: The European Council has now proposed a more moderate regulation. The German Government has made a proposal for some important changes in the Energy Law and connected passages in the Competition Law, which would introduce some more competitive elements into the system without anticipating the results of a competitive process.

    One major objective of the introduction of emissions trading in the European Union was to promote innovation towards mitigating climate change. Focusing on the German electricity industry, the extent to which this objective has been achieved up to now and how the design of the trading scheme could be improved towards achieving the intended objective shall be analyzed in this thesis. These questions are tackled in the thesis from a theoretical and an empirical perspective. The theoretical analysis was largely based on neoclassical environmental economics by using an algebraic model which allowed for comparison of the relevant companies' profits under various configurations of the analyzed design options. The empirical analysis was grounded on two surveys of the electricity industry - one before the start of emissions trading, the other after two and a half years of experience - which enabled identification of the concrete changes in the companies' perceptions and attitudes towards innovation due to the introduction of emissions trading. The analysis reveals some indications that the instrument has basically functioned as originally intended although it has certainly not yet developed its full potential in terms of promoting innovation towards a more climate friendly electricity system. From an environmental innovation perspective the following improvements are essential: (1) Closure provisions should be abolished as soon as possible because they basically extend the lifetime of old installations and thus rather delay innovation. (2) Fuel-specific allocation to new entrants should also be abandoned since it eliminates - at least partly - the incentives to shift investments towards technologies which use more carbon friendly fuels such as natural gas or biomass. (3) Introducing full auctioning for the electricity industry would remedy both of the above-mentioned weaknesses and at the same time eliminate the windfall profit generated by free allocation of allowances

    Government regulations on health, safety and environment have been poppular blamed for the declining productivity in U.S. coal mines since 1970. The stagnation in the coal industry east of the Mississippi is alleged to have been caused by this declining productivity and by the growth of cheaper and cleaner coal production west of the Mississippi. Economic evidence suggests, however, that productivity declines were more due to a relative lowering of labor costs in comparison with coal prices and due to work stoppages. The development of western coals fields was spurred by growth in local demand and had only a relatively small impact on coal production east of the Mississippi. Problems of the eastern coal industry are rooted mainly in slow economic growth in eastern U.S. which must be addressed in the long-term interests of the eastern coal industry. ?? 1987.

    Coal consumption is growing up so fast and coal reserves are so abundant that coal might overtake petroleum in the future. The worldwide environment will not gain anything in this evolution except if 'clean coal' technologies make a significant jump. What is the driving force of this coal development? The pitfall encountered by nuclear energy and the rise of natural gas prices have been favorable conditions for the development of coal but they cannot hide the worldwide metamorphosis of coal industry. From China, undisputed world leader, to the USA, without omitting India, Russia and the big exporting countries (Australia, Indonesia, South Africa, Colombia), a new map is drawing up. In all these countries, coal companies are concentrating and internationalizing, open new strip mines and new commercial paths. The understanding of this metamorphosis has become one of the keys of the energy prospective and geopolitics of the 21. century.

    This study explores crisis management/communication practices within the coal industry through the lens of high reliability organization (HRO) concepts and sensemaking theory. In-depth interviews with industry executives and an analysis of an emergency procedures manual were used to provide an exploratory examination of the status of crisis management within this industry, a context in which crisis management/communication may be viewed as an opportunity to improve existing negative perceptions or generate more favorable attitudes among stakeholders. Findings suggest that although companies place great emphasis on the technical response to a crisis, the lack of crisis communication components in overall planning strategies prevents some companies from being able to adequately respond to a crisis situation.

    Full Text Available In 1951, six European countries founded the European Coal and Steel Community (ECSC, which they hoped would be a first step towards more European integration and which they hoped would provide a common legal framework for their coal and steel industries. The main aim of the ECSC was to make sure that the German coal and steel industries would never again reach their prewar capacities, which according to many had played a part in the coming of World War II. Another important aim was to forestall any attempt of the USSR to conquer West Germany. This article constitutes a case study of the regional concentration of the coal and steel industries in the six ECSC countries, and it investigates whether the importance of certain coal and steel producing regions within the ECSC changed between 1952 and 1967. Furthermore, an analysis is conducted of how the concentration ratios of the ECSC's industries differed among the six countries, whether these differences changed over time, how this influenced the size and number of coal and steel firms and whether the ECSC succeeded in its initial aim of keeping West Germany small.

    From the industrial revolution to the 1960's, coal was massively consumed in Europe and its utilization was constantly raised. In the aftermath of World War II, coal had also an important part in reconstruction of Western Europe's economy. However, since the late 1960's, its demand has been declining. There is a (mis)conception from a number of policy makers that saying coal mining and utilizations in Europe is unnecessary. Therefore in the European Union (EU) Green Paper 2000, coal is described as an 'undesirable' fuel and the production of coal on the basis of economic criteria has no prospect. Furthermore, the commitment to the Kyoto Protocol in reducing greenhouse gases emission has aggravated this view. Faced with this situation, the quest for the future of coal industry (mining and utilization) in the lines of an energy policy is unavoidable. This dissertation did a profound inquiry trying to seek answers for several questions: Does the European Union still need coal? If coal is going to play a part in the EU, where should the EU get the coal from? What should be done to diminish negative environmental impacts of coal mining and utilization? and finally in regard to the CO 2 emission concerns, what will the state of the coal industry in the future in the EU? To enhance the analysis, a system dynamic model, called the Dynamics Coal for Europe (the DCE) was developed. The DCE is an Energy-Economy-Environment model. It synthesizes the perspectives of several disciplines, including geology, technology, economy and environment. It integrates several modules including exploration, production, pricing, demand, import and emission. Finally, the model emphasizes the impact of delays and feed-back in both the physical processes and the information and decision-making processes of the system. The calibration process for the DCE shows that the model reproduces past numbers on the scale well for several variables. Based on the results of this calibration process, it can

    This paper describes several packages of microcomputer programs developed for designing and managing the coal preparation plants. Three parts are included: Coal Cleaning Package (CCP), Coal Preparation Optimization Program (CPO) and Coal Preparation Computer Aided Design System (CPCAD). The function of CCP is: evaluating and predicting coal cleaning result. Coal presentation process modelling and optimization; coal preparation flowsheet design and optimization. The CPO is a nonlinear optimization program. It can simulate and optimize the profit for different flowsheet to get the best combination of the final products. The CPCAD was developed based upon AutoCAD and makes full use of AutoLISP, digitizer menus and AutoCAD commands, combining the functions provided by AutoCAD and the principle used in conventional coal preparation plant design, forming a designer-oriented CPCAD system. These packages have proved to be reliable, flexible and easy to learn and use. They are a powerful tool for coal preparation plant design and management. (orig.).

    Coal produces more carbon dioxide per unit of combustion energy than other fossil fuels. Therefore, reducing coal consumption is commonly advocated as one way to control greenhouse gas emissions and hence predicted global warming. Australia is highly dependent on coal, both as a primary energy source and as a major export commodity. Action to reduce carbon dioxide emissions by substantially decreasing coal consumption would have a very serious impact on the Australian coal industry and the Australian economy. Australia's dependence on coal and the potential conflict between the objective of further processing Australia's mineral exports and calls to limit carbon dioxide emissions is described. The effect on coal consumption of one scenario for reducing Australia's carbon dioxide emissions from electricity generation and possible effects of global carbon dioxide emission reductions on world coal trade are discussed. 24 refs., 2 tabs., 4 figs

    Within a framework that supports sustainable development, the issues of changing coal markets, environmental policy and climate change, and the positive marketing of coal as a solution to energy demand are discussed. Changes affect both domestic and international markets, and each subset of the market is different. In Europe, coal consumption is declining in contrast with expanding Asian energy markets. Clean coal technologies improve efficiency and make coal more acceptable. The greatest reductions in carbon dioxide emissions can be realized within the least efficient areas of coal consumption, in particular the domestic markets in Asia, eastern Europe, and Africa.

    China's modern coal chemical industry has grown into a certain scale after over a decade of development, and remarkable progress has been made in key technologies. But as oil price collapsed since 2015, the economic benefit of the industry also slumped, with loud controversies in China over the necessity of modern coal chemical industry. The research believes that the modern coal chemical industry plays a positive role in the clean and sustainable exploitation of coal in China. It makes profit when oil price is no lower than 60/bbl, and outperforms petrochemical in terms of cost effectiveness when the price is between 60/bbl and 80/bbl. Given the low oil price and challenges posed by environmental protection and water restraints, we suggest that the state announce a guideline quickly, with adjusted tax policies and an encouragement to technological innovation, so that the modern coal chemical industry in China can grow sound and stable.

    According to industrial organization theory, market structure is a crucial factor to market performance. Based on the VAR model and the data from 1994 to 2014, we revealed the dynamic response route of the market structure to these factors and the change process of contribution rate of these factors to the market structure. It shows that market structure is inertial adjustment; technology advance and industry policy have continuous effects on improvement of market concentration ratio; market size and production scale have sustained negative effects on market concentration ratio; fixed capital has barrier effect, which is mainly the entry barrier effect at the beginning, and then the exit barrier effect continues to play a leading role. Therefore, the government has no need to introduce special policies to encourage merger or expansion on the capacity as enterprises would do it spontaneously; it is necessary to make market access system stricter, to improve exit compensation mechanism and to promote technological innovation; all these policies need dynamic adjustment based on the stages of economic cycle. - Highlights: • The adjustment mechanism of China's coal market structure is revealed. • Technology and industry policy are significant factors to optimize the market structure. • The government need not introduce special policy to encourage merger. • The market access system should be stricter. • Policies strength should be dynamically adjusted based on the economic cycle.

    Full Text Available Purpose: Industry 4.0 represents a special challenge for businesses in general and for SMEs in particular. The study at hand will examine companies´ awareness, readiness and capability to meet this challenge taking into account the special role of SMEs. Methodology: The results of nine studies dealing with this range of topics are examined in the framework of a systematic review and compared with regard to the objective of the study at hand. Findings: The review showed that, as a rule, there is an awareness concerning the relevance of the topic. The readiness and the capability to meet this challenge exist in parts; however, they strongly depend on the enterprise size. The smaller SMEs are, the higher the risk that they will become victims instead of beneficiaries of this revolution.Originality/value: Considering different studies concerning Industry 4.0 the article gives an insight into the dependence of the Industry 4.0 readiness in reference to the company size. This deepens the knowledge in adaption deficits German SME still have and opens different approaches for further research and action plans.

    1995-01-01

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

    Global warming--real or imaginary, friend or foe, carbon dioxide emissions a threat to the planet, benign, or good for agriculture--while the debate rages on, the debaters occasionally seem to pause long enough to agree on one point: coal is the bad guy. There is little doubt that coal combustion must continue as a major contributor to the energy economy for the near to mid-term future. It is likely, though, those environmental pressures on conventional processes for coal utilization will only intensify. This factor alone makes questionable the long-term future. Environmental issues also severely impact the metallurgical coke industry. The traditional coal industry and coal markets of the 20th century are under increasingly intense assault. But why waste coal by burning it? Steady progress is being made in two directions for using coal as a valuable hydrocarbon resource. On the one hand, continuous improvements in computer-based structural modeling, which now include the ability to calculate not only a molecular structure that is consistent with chemical facts, but also some of the physical properties and even the incorporation of water. The increasing reasonableness of such structures places one on the verge of being able to do rational organic chemistry on coals, that is, deliberately to select coals as starting materials for certain desired chemical transformations that will produce high-value chemical products in good yields. This opens a route to chemicals from coal that does not rely on by-product coal tars as the feedstock. On the other hand, excellent opportunities also exist for coals as precursors to high-value carbon materials. Anthracites in particular represent an under-exploited, and as yet poorly explored, opportunity for conversion to graphitic materials. Taking coal in both directions high-value chemicals and premium carbon products represent profitable opportunities for innovation, leadership, and new directions for the coal industry in the 21st

  19. The nexus of the coal industry and the state in Australia: Historical dimensions and contemporary challenges

    Baer, Hans A.

    2016-01-01

    This article presents a historical account of the close relationship between the coal mining industry and the federal and various state governments, thus over time building a state/coal industry nexus in Australia. It examines (1) an early colonial stage extending from the late 18th century to around the time of Federation in 1902 when the nexus emerged; (2) an intermediate stage from the early 20th century to the late 1970s when the nexus became solidified; and (3) a late stage from the early 1980s to the present day when the corporate sector came to dominate the nexus. Both Coalition and Australian Labor Party governments have consistently supported the exploitation of Australia's coal and natural gas, including recently coal seam gas, and supported the expansion of coal ports. An opposition movement has called for leaving coal and coal seam gas in the ground and shifting Australia’s energy production to renewable sources, particularly solar and wind energy. The article highlights how the nexus between coal mining and the state inhibits action on climate change. It argues this can be transcended by energy policy directed at socializing coal mining, wedded to a program of transitioning it to renewable energy production. - Highlights: • A close nexus exists between the coal industry and the state in Australia. • An anti-coal movement has developed in recent years in Australia. • Breaking the coal industry/state nexus requires socialization of energy production. • This would enable a shift from reliance on coal to renewable energy sources.

    Full Text Available Coal use is regarded as one of main sources of anthropogenic propagation of mercury in the environment. The coal cleaning is listed among methods of the mercury emission reduction. The article concerns the statistical assessment of mercury separation between coal cleaning products. Two industrial processes employed in the Polish coal preparation plants are analysed: coal cleaning in heavy media vessels and coal cleaning in jigs. It was found that the arithmetic mean mercury content in coarse and medium coal size fractions for clean coal from heavy media vessels, amounts 68.9 μg/kg, and most of the results lay below the mean value, while for rejects it amounts 95.5 μg/kg. It means that it is for around 25 μg/kg greater than in the clean coal. The arithmetic mean mercury content in raw coal smalls amounts around 118 mg/kg. The cleaning of smalls in jigs results in clean coal and steam coal blends characterized by mean mercury content 96.8 μg/kg and rejects with mean mercury content 184.5 μg/kg.

    Full Text Available As part of rental-resource model and access restrictions to capital and new technologies, the attempts to encourage import substitution made by the government do not generate innovative type of economic development and reconstruction of economy’s manufacturing industry competitive on the domestic market. In conditions of searching for a new model of Russian economy development the analysis of a number of problems such as industry degradation, reducing the competitiveness of Russian producers, the growth of structural imbalances and overcoming the negative macroeconomic trends becomes strategically important. This raises the value of neo-industrialization as the integrator of resource security, scientific and industrial potential of Russian economy and high capacity of the domestic market in the innovative development system. A special role neo-industrialization plays for the economic development of old industrial regions, which include Kuzbass (Western Siberia, Russia. Neo-industrial development of Kuzbass economy should be initiated by the technological modernization of mining machinery and innovative development of coal industry.

    Industry consumes about 40 percent of the total primary energy used in the United States. Natural gas and oil, the major industrial fuels, are becoming scarce and expensive; therefore, there is a critical national need to develop alternative sources of industrial energy based on the more plentiful domestic fuels--coal and nuclear. This report gives the results of a comparative assessment of nuclear- and coal-based industrial energy systems which includes technical, environmental, economic, and resource aspects of industrial energy supply. The nuclear options examined were large commercial nuclear power plants (light-water reactors or high-temperature gas-cooled reactors) and a small [approximately 300-MW(t)] special-purpose pressurized-water reactor for industrial applications. Coal-based systems selected for study were those that appear capable of meeting environmental standards, especially with respect to sulfur dioxide; these are (1) conventional firing using either low- or high-sulfur coal with stack-gas scrubbing equipment, (2) fluidized-bed combustion using high-sulfur coal, (3) low- and intermediate-Btu gas, (4) high-Btu pipeline-quality gas, (5) solvent-refined coal, (6) liquid boiler fuels, and (7) methanol from coal. Results of the study indicated that both nuclear and coal fuel can alleviate the industrial energy deficit resulting from the decline in availability of natural gas and oil. However, because of its broader range of application and relative ease of implementation, coal is expected to be the more important substitute industrial fuel over the next 15 years. In the longer term, nuclear fuels could assume a major role for supplying industrial steam. (U.S.)

    Full Text Available This article shows that since 1949 the extractive industry has undergone a strong process of restructuring when enterprises were nationalized and a strict control over all components of the economy was established. The new leadership of the country had the intention of developing the industrial sector as well, basically laying the foundations of the new Romanian economy where the industrial sector economy would bring considerable income. This program will lead to the development of the energy sector in Romania also, thus contributing to a great extent to the development and consolidation of coal and gas extraction. Despite of all the economic and social development achieved during the period 1950-1989, at the end of it, Romania ranked a marginal position in the European countries hierarchy since between its level of development and the market economy developed countries large gaps in respect to the main economic and social indicators occurred.

    The German coal mining industry is undergoing standard-setting radical changes. On the basis of political decisions in February 2007 the strategic management development was re-aligned. Increase in productivity to reduce costs remains the first aim. Over 50% of underground shifts are required in infrastructure areas, i.e. in coal production and material transport. Continuous work is being undertaken to improve transport technology with technical innovations such as the automated diesel trolley. In addition the entire logistics chain is being made increasingly transparent by the use of new information technology (e.g. PDAs in conjunction with WLAN) and can thus be controlled efficiently on the basis of this process data. Technical innovations are being introduced in the conveyance of bulk materials. The entire conveyance in a mine is always realistically simulated by measurement of the individual volumetric flows. Optimised process control is possible on this basis. (orig.)

    The coal industry has proved to be one of the most strategically important but also one of the most problematic industries in China. Closing small township and village owned (TVE) coalmines, declaring loss-making state-owned (SOE) mines bankrupt, and building up modern coal corporations are all causing huge difficulties for the government. The main reason for the problems now facing the industry is the fact that TVEs, SOEs and coal corporations were encouraged to meet different needs at different times and now all face different challenges from development, transition and globalization. This article uses research from the three major categories of coal companies in China to demonstrate that, while these three parallel challenges do necessitate reform in the industry, this reform must be handled cautiously, innovatively and in a balanced way.

    2011-11-01

    Full Text Available It is estimated that about two-thirds of global coal is used for power generation and that, in the next 20 years, over 70% of the demand for coal will come from China and India. Coal accounts for approximately 41% of the world's electricity generation. Demand for thermal coal is influenced by factors that include availability, prices of competing products such as oil, gas and nuclear power, and the demand for electricity. The aim of this article is to provide an exposition of supply chain dynamics within the South African coal mining industry and to argue for a more efficient and collaborative supply chain. The authors attempt to investigate at local and global level, the current trends pertaining to the level of reserves, production and consumption of coal. The article further demonstrates the shortcomings of current logistics in meeting the demand for coal in both domestic and export markets. The article draws from secondary data sourced from academic papers, government and agency documents in the exposition of the coal mining supply chain. The paper concludes by recommending the need for a scientific study on supply chain constraints facing the coal mining industry in South Africa.

    1982-01-01

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

  18. Reserve reporting in the United States coal industry

    2012-01-01

    United States energy policymaking can be better supported with accurate and consistent data on coal reserves, both in the public and private sectors. In particular, reserve data for coal and other energy resources should be directly comparable so that decision-makers can easily understand the relationship among available resources. Long-term policy and investment choices regarding energy security, the environment, and resource allocation depend on accurate information, but existing and easily available data on the magnitude of geologically, environmentally, economically, socially, and legally accessible coal reserves are of insufficient quality to guide such decisions. Even still, these data are often presented for use in policy and energy analysis. Currently, coal reserves are overstated relative to competitor energy resource reserves, in part because coal reporting standards have historically been more liberal and vague than standards for resources like natural gas. Overstating the marketable coal resource could lead to inefficient allocation of limited capital investment that can be difficult to reverse. US government bodies like the Energy Information Administration, United States Geological Survey, Securities and Exchange Commission, and Bureau of Land Management can help correct deficiencies by clarifying standards and collecting data that are relevant for decision-makers, such as energy-based reserve information. - Highlights: ► US Coal reserves are important to public and private policy and investment decisions. ► Poor quality data and coal reserve overreporting misrepresent reality. ► Choices made based on bad information can lead to long-term capital misallocation. ► Numerous government agencies are tasked with providing public data on coal reserves. ► Clearer, more restrictive reserves reporting standards can aid decision-makers.

    1989-01-01

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

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

    This research was aimed at estimating possible Coal workers’ pneumoconiosis (CWP) cases as of 2012, and predicting future CWP cases among redeployed coal workers from the Fuxin Mining Industry Group. This study provided the scientific basis for regulations on CWP screening and diagnosis and labor insurance policies for redeployed coal workers of resource-exhausted mines. The study cohort included 19,116 coal workers. The cumulative incidence of CWP was calculated by the life-table method. Possible CWP cases by occupational category were estimated through the average annual incidence rate of CWP and males’ life expectancy. It was estimated that 141 redeployed coal workers might have suffered from CWP as of 2012, and 221 redeployed coal workers could suffer from CWP in the future. It is crucial to establish a set of feasible and affordable regulations on CWP screening and diagnosis as well as labor insurance policies for redeployed coal workers of resource-exhausted coal mines in China.

    2001-01-01

    In Europe, the process of creating a single energy market is under way. The 1998 Gas Directive established an important date for the European gas industry. On 10 August 1998, ''Directive 98/30/EC of the European Parliament and of the Council of 22 June 1998 concerning common rules for the internal market in natural gas'' came into force. It had to be transposed into national law by the EU member states within two years, i.e. by 10 August 2000. The Directive is a cornerstone in establishing a competitive gas market in the European Union. It is the outcome of several years of negotiations and can be regarded as a compromise between the various interests. On the whole, it leaves EU member states with sufficient scope for adequately taking account of national characteristics in keeping with the principle of subsidiarity. The process of transposing the Gas Directive into the national law of individual EU member states is being closely followed by the European Commission. While acknowledging all the progress made in the single market process, the Commission still detects shortcomings in the implementation of the Gas Directive on the road to an actual single market. This is seen as a justification for new initiatives and intervention, even though the new political framework for the gas industry has not yet been tested in practice and been able to prove itself on a broad scale for any length of time. In the debate on liberalisation, tried-and-tested instruments of secure and market-oriented gas supply on the European continent long-term supply contracts with take-or-pay clauses and competitive oil-indexed gas prices have also come under scrutiny. However, even under the conditions of liberalisation, security of supply has to be achieved mainly by a balanced mix of supply sources and by long-term supply contracts, including competitive pricing as ensured by so-called oil indexing. In the further liberalisation of west European gas industries, it will be essential to ensure

    Poduction and industrial use of brown coal dust in the German Democratic Republic are reviewed. Dust production in 14 brown coal briquetting plants increased from 818.4 kt in 1980 to 2064 kt in 1984 and will exceed 4000 kt in 1990. Quality parameters of dusts according to the TGL 15380 industrial standard are listed. The railroad car loading and shipping technology is explained with the example of modern facilities of the Schwarze Pumpe briquetting plant: dust bunkers of 200 t storage capacity, pneumatic feeding and telescope discharge systems with nitrogen gas inertization, fire prevention, and railroad car cleaning equipment, rail track heating for improved winter loading conditions, etc. Since 1979 the Deuna, Karsdorf and Bernburg cement plants have been converted to brown coal dust combustion after installation of new fuel dust shipping, storage and combustion equipment. Substitution of heating oil and gas in metallurgical blast furnaces by brown coal dust is further described. Techogical advantages of the pneumatic KOSTE fuel feeding method are enumerated.

    It's not only its role as a coal producer which makes China to the subject of talks everywhere. China has a high economic growth despite of the global economical crisis and SARS. China shows highest scientific and technical performance, e.g. with the space flight of the first Chinese astronaut. The Transrapid is running in Shanghai, in 2003 Volkswagen has sold more cars in China than in Germany and, statistically, 2,5 Chinese share one cell phone, i.e. presently there are 500 million cell phones in China, tendency increasing. Observing the developments in Beijing or even better in Shanghai, Shenzen, Guoangou (Kanton) gives you a feeling for dynamics and economic growth which we have been missing in Germany for a long time. This national economy has been growing rapidly thus increasing also the hunger for energy. To feed this hunger is one of the main tasks of the Chinese central government; this is the only way to maintain the economic growth in the future. The economic growth is needed urgently if the changes in economy are to be implemented by the WTO and globalisation of the markets. China needs an economic growth rate of 8% in order to create new jobs needed to make for the ones breaking away in the old, government-controlled enterprises due to the new orientation in its industry. As mentioned before: energy and especially hard coal are key and engine of this development. [German] China ist nicht nur als Kohleproduzent derzeit in aller Munde.

  11. Birth and first steps of mineral coal industry in the USA

    Martin-Amouroux, Jean-Marie

    2015-10-01

    The author proposes a brief history of the emergence of a mineral coal industry in the USA. He notices that wood has been the first source of energy used by settlers for housing heating, and then in industry and transports for heat and steam production. As demand and supply conditions were bad, coal production, although mining sites had been quickly identified and used, only emerged from the 1840's. Different kinds of coal (anthracite, bitumen) have been extracted depending on the region. Then, urbanisation and industrialisation created new opportunities for coal, and the share of coal regularly increased. The author describes how the coal industry was organised: seven regions, central position of Pittsburgh. He outlines the tremendous growth of coal production between 1840 and 1913; comments the distribution of this production among the different states. He describes and comments how this production has been industrialised. This industrialisation resulted in a dramatic increase of productivity between 1890 and 1910. He finally evokes the rather late creation of federal bodies

    Coal consumption is growing up so fast and coal reserves are so abundant that coal might overtake petroleum in the future. The worldwide environment will not gain anything in this evolution except if 'clean coal' technologies make a significant jump. What is the driving force of this coal development? The pitfall encountered by nuclear energy and the rise of natural gas prices have been favorable conditions for the development of coal but they cannot hide the worldwide metamorphosis of coal industry. From China, undisputed world leader, to the USA, without omitting India, Russia and the big exporting countries (Australia, Indonesia, South Africa, Colombia), a new map is drawing up. In all these countries, coal companies are concentrating and internationalizing, open new strip mines and new commercial paths. The understanding of this metamorphosis has become one of the keys of the energy prospective and geopolitics of the 21. century. Content: 1 - entering the 21. century with the energy source of the 19. century?; 2 - consumption growth: new trends; 3 - the USA: the Saudi Arabia of coal; 4 - the unexpected rebirth of coal in Russia; 5 - China, world leader of coal industry; 6 - India and south-east Asia are entering the race; 7 - the rise of exporting industries; 8 - international markets and competitive dynamics of industries; 9 - advantage and drawbacks of coal during the coming decades; 10 - will clean coal technologies be ready on time?; 11 - technical appendix.

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

    Improved processes are available to give low-temperature distillation products economic importance. Low-temperature distillation is limited to the utilization of high-volatile nut coals and briquets. The coke formed can be used as a smokeless fuel, and the tar directly as a fuel oil. Phenols can be extracted, in order to work up the residue into fuel oil and motor fuel. Large deposits of coal in Upper Silesia and in the Saar District are suitable for low-temperature distillation.

    Cardiovascular disease (CVD) is likely to increase in incidence. Foods with cardioprotective functions, e.g. specific functional food, could reduce CVD risk factors and hence CVD incidence. Little is known about industrially modified foods with cardioprotective functions. In a large German sample (n = 1007), attitudes of consumers in Germany towards industrially produced cardioprotective food were assessed using Cluster analyses. Consumers were contacted via telephone and interviewed using questionnaires. Overall, about 25% knew about industrially produced food with cardioprotective function. Our analysis revealed a small but determined group of consumers who think very skeptical about cardioprotective products, but we also identified a favorable group. These two groups only differed in age, with the skeptical group being ten years older. The rising number of industrially modified products with potential cardioprotective benefit is met by skepticism and a lack of knowledge by German costumers. If large scale studies show health benefits of these products, these will need to be better communicated to German customers in order to address possible doubts or concerns and to encourage healthy eating habits in consumer eating behavior.

    2008-09-01

    Full Text Available Regional development within the Ruhr district – from the formally centre of the coal and steel industry to a centre of tertiary services. The Ruhrgebiet (Ruhr district is an urban agglomeration in the western part of Germany with a population of approximately 5.3 Million, covering an area of 4.435 km². It’s part of the metropolitan area of Rhine-Ruhr with more than 10 Million inhabitants living in an area of about 10.000 km².The black coal resources, deposited during the carboniferous area form the natural backbone for the development of the largest region of coal, iron, and steel industry in Europe. The economy of the Ruhrgebiet was unidirectional dominated for more than 150 years by four heavy industry sectors, black coal, steel, chemical industry and energy production. But later, when petroleum and natural gas and cheaper imported black coal conquered the German market and, as well, steel could be produced at a reduced rate elsewhere in the world the booming producing industry quasi collapsed. Thus, the Region is characterized by an above average unemployment since the mid 70ies. More than 50% of the 1 Million jobs in the region were lost, while only 300.000 new jobs could be added within the service sector between 1980 and 2002. The economic and social structural change within the Ruhr district is primarily based on the expansion of services like advertisement, science, development, transport logistics, consulting, and design. But also the cultural and tourist branches are characterized by growing figures. The BIP, produced within the Ruhrgebiet, is about 26% of the BIP of North-Rhine-Westphalia or 6% of Germany’s BIP. In comparison, the metropolitan area of São Paulo produces 17% of the national BIP of Brazil.

    Nowadays preserving nature, recycling or reusing materials are good policies. Around ten million tires are put out by year in Brazil, and it is not known for how long they will remain in environment till their complete degradation. This research used tires to replace coal in ceramic processing. In this way it helps to protect environment, to reduce the consumption of mineral deposits and to save money. Results show that tire powder can replace coal to obtain ceramic material, using one percent of tire. Experiments were carried out using TA instruments SDT 2960, in air or nitrogen atmospheres, at heating rate of 10 C/min., flow 120 ml/min. TG/DTA curves of tire and coal have exothermic events at close temperatures between 450-600 C. At range of temperatures clay have endothermic events. (orig.)

    1985-01-01

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

    2016-11-01

    Full Text Available Introduction: Senior managers’ attitudes towards safety are very important regarding the safety practices in an organization. The study is to describe the current situation of senior managers′ attitudes towards safety in the Chinese coal industry. Method: We evaluated the changing trends as well as the reasons for these changes in the Chinese coal industry in 2009 and in 2014 with 168 senior manager samples from large Chinese state-owned coal enterprises. Evaluations of 15 safety concepts were performed by means of a questionnaire. Results and Conclusions: Results indicate that, in 2014, three concepts were at a very high level (mean > 4.5, and six were at a relatively high level (4.5 > mean > 4.0. Analyses of changing trends revealed that nine concepts improved significantly, while four greatly declined in 2014 compared to those in 2009. The data reported here suggest that the reasons for the significant improvement with respect to the nine concepts include the improvement in social and legal environments, the improvement of the culture of social safety, workers′ safety demands being met, and scientific and technical advances in the coal industry. The decline of the four concepts seemed to be caused by a poor awareness of managers in the coal industry that safety creates economic benefits, insufficient information on safety, inadequate attention to the development of a safety culture and safety management methods, and safety organizations and workers′ unions not playing their role effectively. Practical Applications: We therefore recommend strengthening the evidence that safety creates economic benefits, providing incentives for employees to encourage their participation in safety management, and paying more attention to the prevention of accidents in coal mines via safety organizations and unions. These results can provide guidelines for workers, industrialists, and government regarding occupational safety in the whole coal industry.

After this period public companies in this sector will finance the costs of current production and investment entirely by their revenue. This article presents a short literature review regarding the subsidization of coal industry, shows the evolution of the mining industry in Romania so far, and identifies opportunities for continuing coal production after December 31, 2010 without state aid. The paper concludes that the abolition of subsides in is a positive measure but it must be taken gradually and responsibly, in order to ameliorate the negative effects on social end natural environment.

    The article is written based on some results of the long-term scientific research of the problem related to the urgent need to find the ways of training personnel for the innovative coal industry in the higher education system. This is due to the fundamental changes in the Russian social and economic conditions: the change in the social system and the owner of the coal industry, the emergence of new technologies in the field of coal mining and processing, and in the management of these processes. At the same time, the system of training specialists for the coal industry in the higher education institutions has largely remained unchanged: technologies and principles of training, scientific approaches and concepts take little account of the changed situation, traditional views of specialists work-ing in the university continue to dominate innovative ideas. Many innovations, especially related to technology and the principles of education, struggle to make their way into the higher education system. The article substantiates the urgency of the problem of training personnel for the innovative coal industry in the higher education system, as well as the importance of scientific analysis of the problem in order to find the ways to solve it.

  12. ECONOMIC AND THEORETICAL ASPECTS OF PLANNING EFFECTIVE ACTIVITY OF ENTERPRISES IN THE COAL INDUSTRIES

    Full Text Available Relevance and purpose of the study. Under modern conditions, the share of loss-making enterprises of the coal industry is still high. This brings the solution of the problem of improving the efficiency of their activities up to date. It also determines the purpose of this research. Research methods: scientific generalization, system and factor analysis, and statistical modeling are used in the present work. Results. The article discusses the economic and theoretical aspects of planning the effective activities in the coal industry. The paper analyzes the elasticity of the unit cost price in terms of its labor productivity. It also deals with the elasticity of the volume of output in terms of labor productivity. This indicates that the existing coal mining technologies have, to some extent, exhausted their advantages in the coal industry. They require a change on the achieved level of the capital-labor ratio. It is recommended to strive to ensure advanced ratio of growth of labor productivity of workers compared to the growth rate of unit costs. This should be done at the introduction of a new technology at the enterprises of the coal industry. The advanced ratio of growth in output compared to the growth rate of labor productivity of workers should also be guaranteed. The early growth rate of revenue from sales compared to the growth rate in total costs of production should be provided. The advanced ratio of profit growth compared to the growth rate of revenue from sales has to be provided as well. It is proven that for coal industry enterprises the type of competitive advantages called “the lowest costs” can be the only acceptable one in comparison with other types. We have considered the requirements to the new developed technologies for coal mining. They are as follows: the value of marginal profit in the planned period should be more than the fixed costs of the enterprise; the value of marginal profit in the planned period should be more

    A comparison was made between two belt blending methods; using either a compartment hopper or feeder belts. The results indicated that in this case the system with feeder belts gave a more consistent proportioning of materials. Coal when formed into a heap was shown to segregate dependent on size fraction. The level of segregation for each size fraction was quantified using ANOVA statistics. Any measure taken to mitigate this segregation could then be properly assessed. Some aspects of the segregation evident in the heap arose in previous handling steps showing that such effects are transmittable along a process stream. Singles coal when pneumatically conveyed in dilute phase will segregate in the conveying pipeline. Segregation in the direction of travel was minimal in dense phase conveying although the materials tested separated through the depth of the pipe. A full scale experimental programme investigating segregation in both dense and dilute phase is currently underway. 7 refs., 2 figs., 4 tabs.

    Heading machines have assumed a very important place in underground roadway drivage. They are not only a compromise between ''drill-and-blast'' technique and full-face machines, but are also an economic and versatile form of mechanised roadway drivage. Since the advantages gained by heading machines are considerable, the use of these machines is becoming popular in underground roadway drivage. Experience with continuous miner and heading machines in Indian coal mines is very limited compared to that of Western countries. In 1964-65, for the first time, two units of Lee Norse Miner were used at Kunostoria Colliery of Bengal Coal Company. In 1966, two units of Joy Continuous Miner were introduced at Chalkari Colliery of National Coal Development Corporation, but had to be adandoned because of heavy make of water at the installation site. A Russian PK-3 heading machine was used limitedly during the development of Banki Colliery, Madhya Pradesh. A Demag Unicorn VS-1 machine operated for the development of roadways at Jitpur and Chasnala Collieries of IISCO between 1967-70. With this machine, progress of 7 m per day was attained in level roadways and of about 2 m per day in steep raises.

    Organizational models are analyzed for underground black coal mining in Poland from 1945 to 1984. From 1945 to 1949 organizational model of coal mining was based on selected solutions successfully tested in pre-war Poland. Coal mining was supervised by the Central Board of the Coal Industry. Coal mines were grouped in 8 and later in 10 mine associations. In 1949 the Central Board was dissolved and replaced by the Ministry of Mining and Power Generation. Role of Mine Associations was modified. Further changes were introduced in 1957. Power of Mine Associations in relation to individual coal mines increased. From 1972 to 1975 plans for a structural reform in the coal industry were developed but never realized. From 1980 to 1981 a program of structural changes in management of coal industry (in particular, underground coal mining) was developed. From 1982 to 1984 provisions of the economic reform in relation to coal mines were temporarily suspended. In 1984 a new organizational structure of the coal industry was introduced. The structure is similar to traditional structures used in previous decades (stronger position of mine associations, which since 1984 have been called Mine Unions, etc.). 9 references.

Considerable attention is given to the organization of bookkeeping in production associations, and computer-mechanized bookkeeping. The textbook is intended for students at mining schools and may serve as a practical aid to bookkeepers, economists, and finance personnel at enterprises and associations of the coal industry. 40 tables.

  17. Restructuring and privatising the coal industries in Central and Eastern Europe and the CIS

    International Nuclear Information System (INIS)

    Brendow, K.

    1999-01-01

    This paper reviews coal industry reforms in central and Eastern Europe (CEE), including the former GDR and Estonia (oil shale), and the Commonwealth of Independent States (CIS). It describes achievements and failures during the last ten years on the road to an efficient, viable and environmentally acceptable coal industry playing the various roles assigned to it by governments as part of their energy policies. Obeying to conflicting objectives, coal-restructuring policies can best be described as stop-go policies. As a result, between 1990 and 1998, production declined by 41%, the number of pits by 26% and the number of employees by 45%. Productivity rose by only 8% in the region as a whole. At present, 80 to 90% of coal production is actually or virtually profitable under local or national circumstances. Turning virtual into actual profitability depends as much on continued reforms (unbundling of profitable from unprofitable mines, customerization of mines, equity privatisation) as on a fresh assessment, by investors, of two major opportunities: mine-utility partnerships and untapped productivity gains. These opportunities are growingly recognised by the business community: by 1998, 20% of coal production in the region are owned by equity investors, domestic and foreign. With, these opportunities in mind and assuming economic recovery, WEC, IIASA, IEA, DOE* (*World Energy Council, International Institute for Applied Systems Analysis, International Energy Agency, US Department of Energy) and national governments project a medium-term (2010,2020) increase of coal production against 1998 of about 20%, mostly in the CIS.

  18. Analysis of antitrust activity in the coal industry: 1964--1974

    Energy Technology Data Exchange (ETDEWEB)

    Hinson, W.R.

    1974-01-01

    During this period antitrust activity by the government in the coal industry was of a token nature and did not prevent (1) large investments in coal and uranium by large oil companies, nor (2) concentration with industry by large companies buying out small companies. A major result was the buying up of coal reserves, which were thus unavailable to small companies and hindered them from competing. Neither the government nor public utility companies did much to deter these developments and the results of the few court suits that were brought were not effective in discouraging the process. In fact, the widespread acceptance of nolo contendere pleas by the judicial system could make it profitable for a coal company to violate the antitrust laws. Several recommendations are made: (1) for more vigorous antitrust activity (with nonacceptance of nolo contendere pleas); (2) nationalisation of coal reserves (with bidding for reserves to be mined by competing companies); (3) a reporting system for ownership of coal reserves; and (4) encouragement of electric utilities to file private suit when anticompetitive behavior is suspected.

    1979-01-01

    After recalling the importance of coal in the cement industry up until the end of the 1950s, and the regeneration of interest in this fuel, the author presents some views on the stocking of coal, on its preparation and on its application for firing. The advantages of linear stocking and of de-stocking by the 'front slice' method to ensure good homogenization are described. The precautions to be taken during the fine-grinding process and the transport of the pulverized coal in order to prevent coal-dust explosions are discussed. The main firing systems (direct, semi-direct and indirect) are discussed and their respective advantages and drawbacks examined. (In French)

    Energy Technology Data Exchange (ETDEWEB)

    1953-01-01

    Research into low-temperature carbonization has recently been stimulated because this process can be applied to coals that are not suitable for treatment by the usual high-temperature method. However, in spite of the value of the coke produced by low-temperature carbonization as a smokeless fuel, this process has not proved economical in Germany. Research has therefore been directed towards a more profitable utilization of the tar, and this government publication reports experiments on its detailed analysis by distillation and other methods. The book also includes descriptions of the various types of plant used for low-temperature carbonization and presents a brief history of the process.

  1. Parameters of Regional Cooperative Behavior in the German Biotech Industry – A Quantitative Social Network Analysis

    DEFF Research Database (Denmark)

    Mitze, Timo; Strotebeck, Falk

    We analyse the determinants of network formation in Germany’s biotechnology industry using social network analysis combined with a regression approach for count data. Outcome variable of interest is the degree centrality of German regions, which is specified as a function of the region’s innovative...... and economic performance as well as biotech-related policy variables. The inclusion of the latter allows us to shed new light on the question to what extent R&D-based cluster policies are able to impact on the formation of the German biotech network. Our results show that policy indicators such as the volume...... of public funding for collaborative R&D activity are positively correlated with the region’s overall and interregional degree centrality. However, besides this direct funding effect, we do not observe any further (non-pecuniary) advantages such as prestige or image effects. Regarding the role played...

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

  3. Energy rent and public policy: an analysis of the Canadian coal industry

    International Nuclear Information System (INIS)

    Gunton, Thomas

    2004-01-01

    This paper analyses issues in resource rent through a case study of the Canadian coal industry. A model of the coal industry is constructed to estimate the magnitude of rent and distribution of coal rent between government and industry over the 30-year period from 1970 to 2000. Disaggregation of results by coal sector shows that rent varied widely, with one sector generating substantial rent and other sectors incurring large losses. The pattern of development of the coal sector followed what can be termed a 'rent dissipation cycle' in which the generation of rent in the profitable sector created excessively optimistic expectations that encouraged new entrants to dissipate rent by developing uneconomic capacity. The analysis also shows that the system used to collect rent was ineffective. The public owner collected only one-third of the rent on the profitable mines and collected royalty revenue from the unprofitable mines even though no rent was generated. The case study illustrates that improvements in private sector planning based on a better appreciation of resource market fundamentals, elimination of government subsidies that encourage uneconomic expansion and more effective rent collection are all needed to avoid rent dissipation and increase the benefits of energy development in producing jurisdictions. The study also illustrates that estimates of rent in the resource sector should disaggregate results by sector and make adjustments for market imperfections to accurately assess the magnitude of potential rent

    A promising solution to many problems that thermal power industry is facing today would be switching from conventional coal dust combustion to coal-water slurries containing petrochemicals (CWSP). Here, we perform an experimental study of the most hazardous anthropogenic emissions (sulfur and nitrogen oxides) from the combustion of high-potential CWSP. We identify the main benefits and potential drawbacks of using CWSP in thermal power industry. A set of components and additives to CWSP are explored that significantly affect the environmental and energy performance of fuels. The anthropogenic emissions from the combustion of CWSP made of widespread coal and oil processing wastes are no higher than those from coal dust combustion. Using specialized additives to CWSP, we can change the concentrations of NO x and SO x several times. The most appealing additives to CWSP are sawdust, straw, charcoal, limestone, and glycerol. They provide better environmental, economic, and energy performance and improve the rheological properties of CWSP. Waste oils and oil sludge added to CWSP may impair the environmental performance but boost the cost and energy efficiency. Using coal-water slurries containing petrochemicals as a fuel at thermal power plants is an environmentally friendly as well as cost- and energy-efficient way to recover industrial wastes.

    2016-02-01

    In the food industry the subject of food losses is of great importance due to economic balance and an efficient application of resources as well as the development of an efficient food chain system. This paper presents the explorative results of a quantitative survey of leading companies of the German food industry to evaluate the relevance and handling of this issue. The investigation reveals that the topic food losses have a high significance in the food industry which will probably increase in future. A sample breakdown by branches indicates that the issue has the highest relevance for companies in the confectionery industry. These companies as well as those in the meat and fish industry want to consider the subject prospectively more powerful in their companies. Across the food industry, there is no communication to consumers of the efforts concerning food losses. And companies in the confectionery industry and in the fruit and vegetable industry rather want to engage more powerful in this topic if consumers' interest increases. But in order to minimize food losses at all stages along the supply chain, communication and collaboration at all stages is essential, especially the communication to consumers. Thus, it has to be verified whether a suitable communication can lead to advantages in competition and become an important issue for companies to differentiate from competitors.

    This paper uses an oligopoly model with heterogeneous firms to examine how an industry adjusts to rising import competition. The model predicts that in the short run the least efficient firms in the industry become inactive, surviving firms face a fall in output, mark-ups and profits, and the average productivity of survivors increases. These pro-competitive effects of import penetration on the domestic industry disappear in the long run. The predictions for the short run are confirmed in an ...

  16. Analysis of antitrust activity in the coal industry: 1964-1974

    Energy Technology Data Exchange (ETDEWEB)

    Hinson, W.R.

    1975-01-01

    Antitrust activity in the coal industry from 1964 to 1974 is studied for two major areas: 1) acquisitions and mergers, which involve the structure of the industry; and 2) price fixing, bid rigging, and customer allocations, which deal with the behavior of the industry. The government is criticized for the lack of antitrust activity during this time period. Offences of the antitrust laws by suppliers of fuel could have a chain-reaction effect on all commodity prices, because artificially high fuel prices could force other industries to increase their prices. Several recommendations are made: 1) a special section in both the Justice Department and the Federal Trade Commission should be established to handle violations of the antitrust laws occurring in the ''energy market''; 2) nolo contendere pleas and other forms of a consent settlement should be denied as an option for any energy concern accused of transgressing the antitrust laws; 3) all known coal reserves in the U.S. should be rationalized and placed under the supervision of the Federal Energy Administration; 4) a National reporting system for the ownership of coal reserves should be established; and 5) public regulatory commissions should be encouraged to order electric utilities to file private suits when anti-competitive conduct is suspected by coal suppliers.

    The decision to phase out nuclear energy and gradually realign the electricity system towards more renewables in the future required some extensive changes to electricity generation transmission. One of the issues to be considered is what role lignite can play in the transformation of the electricity system and what application is offered to Germany and its regions. However, lignite has some stable factors and their development is fairly predictable. Domestic lignite is one such example. Beyond its familiar attributes, 'secure, competitive and economically important for the regions', 'flexibility' is a key word that indicates a new dimension for the German lignite industry.

  20. Analysis of the holistic impact of the Hydrogen Economy on the coal industry

    Science.gov (United States)

    Lusk, Shannon Perry

    As gas prices soar and energy demand continues to grow amidst increasingly stringent environmental regulations and an assortment of global pressures, implementing alternative energy sources while considering their linked economic, environmental and societal impacts becomes a more pressing matter. The Hydrogen Economy has been proposed as an answer to meeting the increasing energy demand for electric power generation and transportation in an environmentally benign way. Based on current hydrogen technology development, the most practical feedstock to fuel the Hydrogen Economy may prove to be coal via hydrogen production at FutureGen plants. The planned growth of the currently conceived Hydrogen Economy will cause dramatic impacts, some good and some bad, on the economy, the environment, and society, which are interlinked. The goal of this research is to provide tools to inform public policy makers in sorting out policy options related to coal and the Hydrogen Economy. This study examines the impact of a transition to a Hydrogen Economy on the coal industry by creating FutureGen penetration models, forecasting coal MFA's which clearly provide the impact on coal production and associated environmental impacts, and finally formulating a goal programming model that seeks the maximum benefit to society while analyzing the trade-offs between environmental, social, and economical concerns related to coal and the Hydrogen Economy.

    Having crossed the threshold into the new millennium the power utilities business finds itself confronted by new challenges. In worldwide terms the uppermost objective is, while taking due account of climatic factors and of the obligations resulting from the various World Climate Conferences held so far, to ensure a sufficient and reliable supply of energy for the world's growing population. The gap between the supply of energy and the demand for energy must be closed. In European terms the situation looks a little different. The supply structure is excellent - characterized more by over-capacity than energy shortage. As a result of the liberalization process that has started, the European power utilities have undergone vital changes. Market influences on the power utilities corporations are massive. Fusions and takeovers are the order of the day. The German power business, like others in Europe, is feeling the effects of these two aspects. Also, at national level in Germany, there is the attempt to reach a new energy consensus. An agreement was reached on the 14. of June 2000 between the German federal government and the power utilities. This laid down regulations on the future operation of German nuclear power plants and the disposal of spent fuel elements - to apply up until the government's planned withdrawal from nuclear power. However, the politicians have yet to answer the question of how, in the long term, a sensibly balanced German energy mix might look. There is not as yet - nor in the foreseeable future is there likely to be - an energy consensus in Germany supported by all social and political groups. The respective approaches and ideas differ too widely. The failure, in the so-called 'Energy dialog 2000', of political parties, environmental organizations, and representatives from industry to achieve any results that might point the way forward and tell us where we are heading shows this all too clearly.

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

    Coal combustion products (CCPs) are formed with the production of electricity in coal-fired power plants. The production of these CCPs has been increased by the years due to legal requirements for flue gas cleaning. The utilisation of CCPS is well is established in some European countries, based on long term experience and technical as well as environmental benefits. As CCPs are defined as waste materials by existing legislation the power industry has to handle the stigma put on the products and hamper the beneficial use. (orig.)

    Results of experimental studies of composite fuel thermal decomposition processes based on T grade coal (Alardinskoe deposit) and timber industry wastes (fine wood) are presented. C, H, N, S weight percentage of each component of composite fuel was determined experimentally. It has been established that with an increase in wood concentration up to 50% in composite fuel, its energy characteristics decrease by less than 3.6%, while the yield of fly ash is 39.7%. An effective composite fuel composition has been defined as 50%/50%. Results of performed experimental studies suggest that it is possible to use composite fuels based on coal and wood at thermal power plants.

    This volume presents a theory of capitalist collective action and a case study of the pre-World War II American coal industry to which the theory is applied. The author examines the irony of capitalist firms that do not want to compete with each other, but often cannot avoid doing so. He then explains under what conditions businesses would be able to organize their competition and identifies the economic and political factors that facilitate or inhibit this organization. The case study not only illustrates the theory, but demonstrates how the competitive relations of capitalist firms are critically important determinants of their political behavior. The author argues that the traditional Marxist concern with conflict between workers and capitalists should be supplemented with a concern for the competitive conflicts among capitalists. Contents are: 1: 1. Economic competition and market organization: the logic of capitalist collective action; 2. Forms of capitalist collective action; Part II: 3. Price and wage games in the bituminous coal industry; 4. Workers organize capitalists: collective bargaining and market organization, 1880-1914; 5. The coal industry on the defensive, 1916-1922; 6. Labor-capital conflict and the disorganization of the coal market, 1921-1928; 7. From free competition to state intervention; Part III: 8. Capitalists, workers, and the state; Bibliography; Indexes.

    The two most common methods of 'blending' industrial coals is either by use of feeder belts discharging onto a central conveyor belt, or by a compartment hopper discharging onto a common belt. These two methodologies were shown to give very similar levels of variance in the proportioning of component coals, over a wide range of discharge conditions. Limited work suggested that belt sampling from the end of the belt gave similar results to the stopped belt and frame technique. The segregation found in heaps formed from binary mixtures of coals was quantified by various statistical methods. These results demonstrated that very high levels of segregation can be expected in almost any heap formed when material is discharged from the belt in either of the two 'blending' methods described above. This can reasonably be expected to be a major factor in the inconsistent supply of a specified blend to a consumer. (orig.)

    Full Text Available This research was aimed at estimating possible Coal workers' pneumoconiosis (CWP cases as of 2012, and predicting future CWP cases among redeployed coal workers from the Fuxin Mining Industry Group. This study provided the scientific basis for regulations on CWP screening and diagnosis and labor insurance policies for redeployed coal workers of resource-exhausted mines. The study cohort included 19,116 coal workers. The cumulative incidence of CWP was calculated by the life-table method. Possible CWP cases by occupational category were estimated through the average annual incidence rate of CWP and males' life expectancy. It was estimated that 141 redeployed coal workers might have suffered from CWP as of 2012, and 221 redeployed coal workers could suffer from CWP in the future. It is crucial to establish a set of feasible and affordable regulations on CWP screening and diagnosis as well as labor insurance policies for redeployed coal workers of resource-exhausted coal mines in China.

    A colliery manager gives his opinions on the requirements of the industry from young graduates of the Technical College of Mining in the Federal Republic of Germany. He suggests that there is a need for young, well educated graduates from colleges and universities; that all young engineers should start their careers in line management; and that technical college education should be operationally relevant. Suggestions are given for improving the current trainee programme at Minster Achenbach colliery.

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

    Through ELPI (electrical low-pressure impactor) based dilution sampling system, the emission characteristics of PM10 and PM2.5 was studied experimentally at the inlet and outlet of dust catchers at eight different coal-fired industrial boilers. Results showed that a peak existed at around 0.12-0.20 microm of particle size for both number size distribution and mass size distribution of PM10 emitted from most of the boilers. Chemical composition analysis indicated that PM2.5 was largely composed of organic carbon, elementary carbon, and sulfate, with mass fraction of 3.7%-21.4%, 4.2%-24.6%, and 1.5%-55.2% respectively. Emission factors of PM10 and PM2.5 measured were 0.13-0.65 kg x t(-1) and 0.08-0.49 kg x t(-1) respectively for grate boiler using raw coal, and 0.24 kg x t(-1) and 0.22 kg x t(-1) for chain-grate boiler using briquette. In comparison, the PM2.5 emission factor of fluidized bed boiler is 1.14 kg x t(-1), much her than that of grate boiler. Due to high coal consumption and low efficiency of dust separator, coal-fired industrial boiler may become the most important source of PM10, and should be preferentially controlled in China.

    The article considers the evolution of the concept of "management". The Internet analysis of the concept of "viral management" was conducted, the results of which testify to the positive trend, the growing interest in scientific circles, the relevance of the chosen direction for further research and the increasing popularity of the viral management among business leaders. The indices of coal and brown coal extraction in Ukraine and Russia for 2010-2016 are analyzed. Among the problems that exist in the coal industry are the following: mine assets have a high degree of deterioration; the equipment is rather obsolete and does not correspond to the world level; among the existing face equipment, the specific weight of longwall mining equipment, road headers, loading machines, and belt conveyors of the new generation is only several percent. Five steps of introduction of the virus management at the enterprise are identified: opening, development, participation, diffusion, sustainability. The principles of introduction of the viral management in the enterprises of the coal industry are offered. It is established that the main idea of the viral management is to "infect" the organization and, mainly, employees with one or another "virus" in the form of a common idea or goal. It is indicated that the viral management assumes a certain automaticity of changes, internal "obsession" with this or other innovation, involvement of an informal personal factor.

  14. Analysis of industrial markets for low and medium Btu coal gasification. [Forecasting

    Energy Technology Data Exchange (ETDEWEB)

    1979-07-30

    Low- and medium-Btu gases (LBG and MBG) can be produced from coal with a variety of 13 existing and 25 emerging processes. Historical experience and previous studies indicate a large potential market for LBG and MBG coal gasification in the manufacturing industries for fuel and feedstocks. However, present use in the US is limited, and industry has not been making substantial moves to invest in the technology. Near-term (1979-1985) market activity for LBG and MBG is highly uncertain and is complicated by a myriad of pressures on industry for energy-related investments. To assist in planning its program to accelerate the commercialization of LBG and MBG, the Department of Energy (DOE) contracted with Booz, Allen and Hamilton to characterize and forecast the 1985 industrial market for LBG and MBG coal gasification. The study draws five major conclusions: (1) There is a large technically feasible market potential in industry for commercially available equipment - exceeding 3 quadrillion Btu per year. (2) Early adopters will be principally steel, chemical, and brick companies in described areas. (3) With no additional Federal initiatives, industry commitments to LBG and MBG will increase only moderately. (4) The major barriers to further market penetration are lack of economic advantage, absence of significant operating experience in the US, uncertainty on government environmental policy, and limited credible engineering data for retrofitting industrial plants. (5) Within the context of generally accepted energy supply and price forecasts, selected government action can be a principal factor in accelerating market penetration. Each major conclusion is discussed briefly and key implications for DOE planning are identified.

    1999-01-01

    The environmental effects of electricity production from different biofuels by means of co-combustion with hard coal in existing coal fired power plants are analysed and compared to electricity production from hard coal alone based on Life Cycle Analysis (LCA). The use of straw and residual wood at a 10% blend with coal in an existing power plant in the southern part of Germany shows that all investigated environmental effects are significantly lower if biomass is used instead of coal. Thus based on the available and proven technology of co-combustion of hard coal and biomass in existing power plants a significant contribution could be made to a more environmentally sound energy system compared to using coal alone.

    The mid-sized embossed German textile industry must face social challenges e.g. demographic change or technical changing processes. Interaction with intelligent systems (on machines) and increasing automation changes processes, working structures and employees’ tasks on all levels. Work contents are getting more complex, resulting in the necessity for diversified and enhanced competencies. Mobile devices like tablets or smartphones are increasingly finding their way into the workplace. Employees who grew up with new forms of media have certain advantages regarding the usage of modern technologies compared to older employees. Therefore, it is necessary to design new systems which help to adapt the competencies of both younger and older employees to new automated production processes in the digital work environment. The key to successful integration of technical assistance systems is user-orientated design and development that includes concepts for competency development under consideration of, e.g., ethical and legal aspects.

  17. The energy demand in the British and German industrial sectors. Heterogeneity and common factors

    This paper estimates energy demands for the German and British industrial sectors over the 1978-2004 and the 1991-2004 samples. From time series models we can conclude that there is a considerable variation in the value of the coefficients across sectors, even though energy demands with sensible parameters can rarely be estimated. When using a panel approach, the ability of some estimators to allow for diversity across subsectors was an important factor in explaining the estimates for price elasticity. On the other hand, correlation across panel members or common factors did not markedly influence our results. With regard to the estimated parameters, our preferred choice for elasticity of economic activity and price in the longer sample is 0.52 and - 0.64. Similar values are found in the case of the shorter samples. Bearing in mind the high price elasticity, energy taxes can be considered an effective strategy for reducing energy consumption. (author)

    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.

  19. Coal utilization in industrial boilers in China - a prospect for mitigating CO2 emissions

    It is estimated from GEF statistical data for 1991 that more than 500,000 industrial boilers (mostly stoker-fired) in China consume over 400 million tons of coal per year. Each year, because of low boiler efficiency, 75 million tons of coal is wasted and 130 million tons of excess CO 2 are emitted. An analysis of 250 boiler thermal-balance test certificates and 6 field visits in three provinces have shown that: (1) boilers with efficiencies of less than 70% account for 75% of the total boiler-population; (2) the main causes of the low efficiencies are high excess air and unburned carbon in the slag and fly ash. The effect of unburned carbon on CO 2 emission is a balance of positive and negative contributions: while the unburned carbon does not produce CO 2 emissions, its replacement carbon, burned at a low efficiency, contributes to a net increase in CO 2 emissions. It seems from the analysis that the average boiler efficiency can be raised to 73% by relatively simple means, such as the size grading of the coal, improved boiler operating practice and some inexpensive equipment modifications. This could then result in savings each year of 34 million tons of coal and a reduction in CO 2 emissions of 63 million tons at an estimated cost of $10 per ton of CO 2 .

    Full Text Available Corporate social responsibility (CSR is built on interaction between companies and the society which is especially important for major companies that exploit natural resources and play the role of city-forming socially significant entities. Various interpretations of the notion of social responsibility define the varying levels of influence companies have on the society, different levels of contribution of companies in the said process and the degree and level of implementation of CSR. The relations between social responsibility and economic results and the effects of implementing CSR policies are often not obvious.This study offers an assessment of present-day state of corporate social responsibility policies in coal companies of Russia and Poland and formulates proposals on implementing social responsibility projects with consideration of state-of-the-art CSR concepts.The results of the study are as follows: the achieved level of social responsibility in coal companies of Russia and Poland has been assessed; it is proven that most companies in the coal industry are at the level of fragmentary application of CSR concepts; an analysis has been carried out of tools available in the area of social responsibility of coal companies.

    Independent power producers will build a substantial fraction of expected new coal-fired power generation in developing countries over the coming decades. To reduce perceived risk and obtain financing for their projects, they are currently building and plan to continue to build subcritical coal-fired plants with generating efficiency below 40%. Up-to-date engineering assessment leads to the conclusion that supercritical generating technology, capable of efficiencies of up to 45%, can produce electricity at a lower total cost than conventional plants. If such plants were built in Asia over the coming decades, the savings in carbon dioxide emissions over their lifetime would be measured in billions of tons. IPPs perceive supercritical technology as riskier and higher cost than conventional technology. The truth needs to be confirmed by discussions with additional experienced power engineering companies. Better communication among the interested parties could help to overcome the IPP perception issue. Governments working together with industry might be able to identify creative financing arrangements which can encourage the use of more efficient pulverized clean coal technologies, while awaiting the commercialization of advanced clean coal technologies like gasification combined cycle and pressurized fluidized bed combustion.

    The fast depletion of fuel oil and the continuous increase in the demand for power is a global issue. In the Philippines, the demand for diesel oil is expected to increase significantly in a 20-year period as projected by the Department of Energy. In line with the Philippine Government's thrust to lessen the dependence on imported energy, the agenda for the search for alternative fuel is highly prioritized. Thus, this paper presents the results of the study on performance analysis and efficiency test of a diesel oil fired industrial steam generator using Philippine Calatrava coal-diesel oil mixture (CDOM) as alternative fuel. A computer program was developed in HyperText Markup Language (HTML{copyright}) and JavaScript{copyright} to aid the computation of the adiabatic flame temperature from the governing system of equations based on the heat interaction between CDOM fuel, combustion air and products of combustion to determine the most desirable alternative fuel. Actual experimentation for the determination of CDOM fuel properties was also conducted to verify the alternative fuel selected through theoretical calculations. Results showed that the CDOM fuel with a particle size passing 75 {mu}m (-200 mesh) sieve having a proportion of 5% pulverized coal-95% diesel oil and 10% pulverized coal-90% diesel oil could be handled throughout the test with no degradation of the industrial steam generator. The steam generator efficiency using diesel oil is close to the steam generator efficiency using both CDOM fuels. 20 refs., 5 figs., 4 tabs.

    Coal-fired combustion is recognized as a significant anthropogenic source of atmospheric compounds in Beijing, causing heavy air pollution events and associated deterioration in visibility. Obtaining an accurate understanding of the temporal trends and spatial variation characteristics of emissions from coal-fired industrial combustion is essential for predicting air quality changes and evaluating the effectiveness of current control measures. In this study, an integrated emission inventory of primary air pollutants emitted from coal-fired industrial boilers in Beijing is developed for the period of 2007–2013 using a technology-based approach. Future emission trends are projected through 2030 based on current energy-related and emission control policies. Our analysis shows that there is a general downward trend in primary air pollutants emissions because of the implementation of stricter local emission standards and the promotion by the Beijing municipal government of converting from coal-fired industrial boilers to gas-fired boilers. However, the ratio of coal consumed by industrial boilers to total coal consumption has been increasing, raising concerns about the further improvement of air quality in Beijing. Our estimates indicate that the total emissions of PM 10 , PM 2.5 , SO 2 , NO x , CO and VOCs from coal-fired industrial boilers in Beijing in 2013 are approximately 19,242 t, 13,345 t, 26,615 t, 22,965 t, 63,779 t and 1406 t, respectively. Under the current environmental policies and relevant energy savings and emission control plans, it may be possible to reduce NO x and other air pollutant emissions by 94% and 90% by 2030, respectively, if advanced flue gas purification technologies are implemented and coal is replaced with natural gas in the majority of existing boilers. - Highlights: • A unit-based emission inventory of coal-fired industrial boilers is developed. • Temporal trend of historical period 2007–2013 and the future till 2030 is

    The construction of an irradiation plant for calibration measurement by means of prompt neutron activation analysis is described. A 5.84 μg and 16.3 μg Cf-252 source serve as neutron sources. Tests have shown an inner centred arrangement to offer the best solution for sources of this strength. The use of the PNAA method for determining sulphur, iron and chloride content in brown coal was tested and calibration curves drawn. The sulphur content of the coal briquettes tested was found to be 0.27% S, the iron content amounting to 0.21% Fe and chloride to 0.06%. These values correlate closely with values obtained from wet chemical industrial analysis. (WI)

Those potential compliance costs in Pennsylvania may exceed $3 billion by the end of the decade. This does not include worst case estimates of over $750 million per year in added operations and maintenance costs. In the face of these expenses, concerns such as jobs and the health of Pennsylvania's coal industry may carry little weight. The Commission cannot relieve companies of their responsibility for complying. Thus, in order to maintain its market among electric companies, coal will have to be competitive both in offering solutions to the emissions requirements of the CAA and in providing acceptable alternatives for future, new generating plants

    A conceptual design study was conducted to assess technical feasibility, environmental characteristics, and economics of coal gasification. The feasibility of a coal gasification combined cycle cogeneration powerplant was examined in response to energy needs and to national policy aimed at decreasing dependence on oil and natural gas. The powerplant provides the steam heating and baseload electrical requirements while serving as a prototype for industrial cogeneration and a modular building block for utility applications. The following topics are discussed: (1) screening of candidate gasification, sulfur removal and power conversion components; (2) definition of a reference system; (3) quantification of plant emissions and waste streams; (4) estimates of capital and operating costs; and (5) a procurement and construction schedule. It is concluded that the proposed powerplant is technically feasible and environmentally superior.

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

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

    1987-03-01

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

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

  13. The German lignite industry. Historical development, resources, technology, economic structures and environmental impact. Study

    International Nuclear Information System (INIS)

    2017-05-01

    Lignite has a key role to play in the transformation of the energy system due to its specific structural features in terms of industry, company history, policy, economics, the environment and regional structures. Understanding these structural features of the German lignite industry is an important requirement for classifying the significance of the lignite industry up to now and for the redesigning of this industrial sector. From these environmental, economic and regulatory structural characteristics, which are interwoven in a variety of ways, the incentives arise for the mining and power plant operators to react to energy price signals or energy policy steering. The aim of this research study is to define these structural features, to compile comprehensively the basic data and information that is not always transparently available, to understand the interactions, to enable the navigation of issues that are partly very complex, and to classify into the long-term developments that are especially important for political and social processes. In 2016 approx. 12 percent of German primary energy consumption was met using lignite. At the same time, lignite has the highest carbon dioxide (CO2) emissions of the fossil fuels; it currently accounts for approx. 19 percent of Germany's total greenhouse gas emissions as well as approx. 46 percent of the total CO2 emissions of the electricity sector. As a result of the mining of lignite and its conversion into electricity, substantial adverse impacts beyond the entry of greenhouse gases into the Earth's atmosphere arise for other environmental media. These impacts include half of Germany's mercury emissions, approx. a third of its sulfur dioxide emissions and approx. a tenth of its nitrogen oxide emissions. Lignite mining in open-cast mines takes up a substantial amount of landscape and soil and requires huge interventions in the water balance. Relatively high costs arise for the recultivation and rehabilitation of the open

    In this study, an integrated water and waste load allocation model is proposed to assist decision makers in better understanding the trade-offs between economic growth, resource utilization, and environmental protection of coal chemical industries which characteristically have high water consumption and pollution. In the decision framework, decision makers in a same park, each of whom have different goals and preferences, work together to seek a collective benefit. Similar to a Stackelberg-Nash game, the proposed approach illuminates the decision making interrelationships and involves in the conflict coordination between the park authority and the individual coal chemical company stockholders. In the proposed method, to response to climate change and other uncertainties, a risk assessment tool, Conditional Value-at-Risk (CVaR) and uncertainties through reflecting parameters and coefficients using probability and fuzzy set theory are integrated in the modeling process. Then a case study from Yuheng coal chemical park is presented to demonstrate the practicality and efficiency of the optimization model. To reasonable search the potential consequences of different responses to water and waste load allocation strategies, a number of scenario results considering environmental uncertainty and decision maker' attitudes are examined to explore the tradeoffs between economic development and environmental protection and decision makers' objectives. The results are helpful for decision/police makers to adjust current strategies adapting for current changes. Based on the scenario analyses and discussion, some propositions and operational policies are given and sensitive adaptation strategies are presented to support the efficient, balanced and sustainable development of coal chemical industrial parks.

  20. Managing produced water from coal seam gas projects: implications for an emerging industry in Australia.

    Science.gov (United States)

    Davies, Peter J; Gore, Damian B; Khan, Stuart J

    2015-07-01

    This paper reviews the environmental problems, impacts and risks associated with the generation and disposal of produced water by the emerging coal seam gas (CSG) industry and how it may be relevant to Australia and similar physical settings. With only limited independent research on the potential environmental impacts of produced water, is it necessary for industry and government policy makers and regulators to draw upon the experiences of related endeavours such as mining and groundwater extraction accepting that the conclusions may not always be directly transferrable. CSG is widely touted in Australia as having the potential to provide significant economic and energy security benefits, yet the environmental and health policies and the planning and regulatory setting are yet to mature and are continuing to evolve amidst ongoing social and environmental concerns and political indecision. In this review, produced water has been defined as water that is brought to the land surface during the process of recovering methane gas from coal seams and includes water sourced from CSG wells as well as flowback water associated with drilling, hydraulic fracturing and gas extraction. A brief overview of produced water generation, its characteristics and environmental issues is provided. A review of past lessons and identification of potential risks, including disposal options, is included to assist in planning and management of this industry.

    Swedish consumption of coal and coke during 1991 and trends in technology, environment and market aspects of coal use are reported. Steam coal use in the heating sector was unchanged from 1991, 1.2 Mtons. Reduced consumption in smaller district heating units (due to conversion to biofuels and gas) was compensated by increased use for power generation in cogeneration plants. Coal consumption in industry fell 0.10 Mton to 0.84 Mton due to lower production in one industry branch. Import of steam coal was 1.1 Mton (down 0.5 Mton from 1990) since new rules for strategic reserves allowed a reduction of stocks. During the last five years stocks have been reduced by 2 Mtons. Import of metallurgical coal was 1.6 Mton, unchanged from 1990. The report also gives statistics for the coal using plants in Sweden, on coal R and D, and on emission laws for coal firing.

    As China continues its double-digit economic growth, coal remains the principal fuel for the country’s primary energy consumption and electricity generation. China’s dependence on coal in coming years makes its carbon emission intensity reduction targets more difficult to achieve, particularly given rising electricity demand from a growing number of Chinese cities. This paradox has led the government to pursue cleaner and more efficient development of the coal industry on the supply side and “low carbon” development of cities on the demand side. To understand and assess how China may be able to meet its energy and carbon intensity reduction targets, this report looks at the recent development of low carbon cities as well as new developments and trends in the coal industry. Specifically, we review low-carbon city and related eco-city development in China before delving into a comparison of eight pilot lowcarbon city plans to highlight their strengths and weaknesses in helping achieve national energy and carbon targets. We then provide insights into the future outlook for China’s coal industry by evaluating new and emerging trends in coal production, consumption, transport, trade and economic performance.

    International the coal market in 2014 was the first time in a long time in a period of stagnation. In Germany, the coal consumption decreased even significantly, mainly due to the decrease in power generation. Here the national energy transition has now been noticable affected negative for coal use. The political guidances can expect a further significant downward movement for the future. In the present phase-out process of the German hard coal industry with still three active mines there was in 2014 no decommissioning. But the next is at the end of 2015, and the plans for the time after mining have been continued. [German] International war der Markt fuer Steinkohle 2014 erstmals seit langem wieder von einer Stagnation gekennzeichnet. In Deutschland ging der Steinkohlenverbrauch sogar deutlich zurueck, vor allem wegen des Rueckgangs in der Stromerzeugung. Hier hat sich die nationale Energiewende nun spuerbar und fuer die Steinkohlennutzung negativ ausgewirkt. Die politischen Weichenstellungen lassen fuer die Zukunft eine weitere erhebliche Abwaertsbewegung erwarten. Bei dem im Auslaufprozess befindlichen deutschen Steinkohlenbergbau mit noch drei aktiven Bergwerken gab es 2014 keine Stilllegung. Doch die naechste steht zum Jahresende 2015 an, und die Planungen fuer die Zeit nach dem Bergbau sind fortgefuehrt worden.

    Full Text Available Noise influence takes one of the leading roles in the development of sensorineural hearing loss (SHL. At the same time professional deafness steadily occupies the 5th place in the structure of occupational diseases in Ukraine over the past few years. Of special importance is the problem of pre-clinical and early diagnosis of occupational hearing deterioration, in sense of timely prophylactic and rehabilitation measures in “risk group” workers. The objective research methods play an important role in the diagnosis of auditory analyzer state. Many scientific studies have shown the diagnostic effectiveness of method of otoacoustic emissions recording in the early diagnosis of lesions of receptor part of auditory analyzer. It is known that SHL of noise genesis largely affects the receptor part of the auditory analyzer, for which the OAE method has great practical diagnostic significance. Objective: to study informativity indicators of otoacoustic emission for the diagnosis of sensorineural hearing loss in various occupational groups of coal workers in Ukrainian mines. Materials and Methods: Auditory function of 87 workers of the coal industry (drifters, miners and longwall miners with different levels of industrial noise and hygienic conditions in their workplaces was: 28 studied drifters (group 1, 25 miners (group 2 and 34 longwall miners (group 3. Work experience in noise in these groups was 17,9±1,0; 23,1±1,0 and 22,2±2,0 accordingly. Noise ratio in drifters was 93,6±4,9 dBA, in miners – 92,9±5,5 dBA and in longwall miners – 86,5±6,04 dBA accordingly, while the maximum permitted level is 80 dBA.

    In this paper, we have developed a model that integrates system dynamics with fuzzy multiple objective programming (SD-FMOP). This model can be used to study the complex interactions in a industry system. In the process of confirming sensitive parameters and fuzzy variables of the SD model, we made use of fuzzy multi-objective programming to help yield the solution. We adopted the chance-constraint programming model to convert the fuzzy variables into precise values. We use genetic algorithm to solve FMOP model, and obtain the Pareto solution through the programming models. It is evident that FMOP is effective in optimizing the given system to obtain the decision objectives of the SD model. The results recorded from the SD model are in our option, reasonable and credible. These results may help governments to establish more effective policy related to the coal industry development.

    2018-01-01

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

    2001-07-01

    The importance of coal for energy and economic security in Russia is being reconsidered. Following revival of the world coal market, Russian coal exports reached a peak of 42 mt in the year 2000. However, coal demand by the national market is low as the economy is oriented towards natural gas. The poor condition of mine transport and mining machinery hampers coal exports. 70% of the country's coal output is from private companies which currently have insufficient funds for investment needed. Rises in railway rates for coal have affected the competitiveness of coal both at home and abroad. However, these problems are not unsurmountable and the market for Russian coal is predicted to grow up to 2005, mainly with coal from the Kuznetsk Basin. From 2005-2010 exports will depend on commissioning of new export-oriented capacity and completion of a railway line and coal terminal.

    Some recent developments in industrial nuclear gauging in Australia are briefly reviewed. Quality control, process control and automation in the mineral and coal industries are based on measurements of the composition and flows of critical process stream. Australia's vast mineral wealth and its importance to the national economy has resulted in CSIRO (Commonwealth Scientific and Industrial Research Organisation) successfully developing and commercializing a variety of nucleonic gauges to meet the needs of the mineral and coal industries. These include gauges for on-line determination of the ash content of coal on conveyor belts, the ash content of solids of weight fraction of coal in slurries, on-stream determination of iron, alumina and manganese in iron ore, bulk analysis of raw feed limestone in the cement industry, and gauges for the measurement of level, moisture, and interfaces. A variety of gauges based on natural radioactivity have also been developed. Instruments based on natural gamma radiation are relatively inexpensive, and free of artificial radiation sources. An on-stream analyser based on natural gamma ray activity has been developed for monitoring the soil content of sugar cane. Significant benefits accrued to industry in using nucleonic gauges are briefly discussed. (author). 18 refs., 8 figs

    This paper discusses the occurrence of silicified tree trunks and stumps in the Boehlen brown coal field. The trees, mainly Taxodium and Sequoia 25 million years old, are located within the top brown coal seam of the deposit and present a major obstacle to excavator operation, together with other forms of so-called 'brown coal quartzite'. The quartz of the silicified trees occurs as opal, cryptocrystalline quartz and low temperature quartz. The separate removal and disposal of this wood as well as efforts made to use selected wood as raw material are briefly summarized. Various products for interior house decoration have been manufactured from the wood. (4 refs.)

    2006-06-15

    This paper examines the geographical transfer of economic knowledge and practices from centres of neoliberalism in North America and Western Europe to post-soviet Ukraine. The paper argues that a 'transition industry' emerged in the wake of the disintegration of the soviet system whose purpose was to realize economic transition in central and eastern Europe. The paper discusses the emergence of a community of academic and professional economists affiliated to international financial institutions and academic and professional economic research organizations in Kyiv engaged in promoting the Washington consensus. This community identified the coal industry, located in the Ukrainian Donbas, as a barrier to structural economic reform and the political re-alignment of the country. The paper then examines the way the World Bank unsuccessfully attempted to force the coal industry to conform to its own policy prescriptions. The example points to the articulation not only of extra-local and internal processes of neoliberalization, but also with indigenous informal marketization. In this instance the World Bank's vision failed to materialize because state power could not be allied to its neoliberal project.

    Coal tar was detected in the 17th century in laboratory experiments based on empirical knowledge. In the 18th century industrial revolution, coal tar was an undesired by-product of iron production and coking plants. It was first used in the 19th century for impregnating railway sleepers. Later developments in atomic theory, new chemical symbols and organic element analysis provided the basis for discovering and chemical characterisation of coal tar constituents. Laboratory experiments with these tar constituents resulted in the first synthetic dyes, the postulation of tetravalent carbon and the resulting structural theory in organic chemistry for systematic synthesis of many tar dyes to substitute natural dyes in the textile industry. The technical application of these syntheses was part 2 of the industrial revolution and the foundation of the chemical industry in Germany, which developed rapidly in the 2nd half of the 19th century. Tar dye chemistry has made a significant contribution to Germany's economic growth and the change from an agricultural to an industrialized country.

    It is shown, that the effective method in analyzing capital expenditure is the use of the economic statistical method. It is a result of the fact that capital expenditure is formed under the influence of a number of factors. On the basis of the coal industry, a model of capital expenditure, in which we found reflection of mining geological, technical, and technical conditions of production, was constructed. A level of capital expenditure is analyzed for various groups of mines and recommendations of a better use of basic industrial capital at coal enterprises is analyzed.

    Coal, as one of the most economic and abundant energy sources, remains the leading fuel for producing electricity worldwide. Yet, burning coal produces more global warming CO 2 relative to all other fossil fuels, and it is a major contributor to atmospheric particulate matter known to have a deleterious respiratory and cardiovascular impact in humans, especially in China and India. Here we have discovered that burning coal also produces large quantities of otherwise rare Magnéli phases (Ti x O 2x-1 with 4 ≤ x ≤ 9) from TiO 2 minerals naturally present in coal. This provides a new tracer for tracking solid-state emissions worldwide from industrial coal-burning. In its first toxicity testing, we have also shown that nanoscale Magnéli phases have potential toxicity pathways that are not photoactive like TiO 2 phases, but instead seem to be biologically active without photostimulation. In the future, these phases should be thoroughly tested for their toxicity in the human lung.Solid-state emissions from coal burning remain an environmental concern. Here, the authors have found that TiO2 minerals present in coal are converted into titanium suboxides during burning, and initial biotoxicity screening suggests that further testing is needed to look into human lung consequences.

    When comparing the West German gas industry to the United States one finds some striking differences in their structure and organisation. The German industry is small but growing, vertically integrated, efficient and scarcely regulated. The US-industry is big, hardly integrated and just recovering from years of frictions caused by successive waves of misguided regulations which were interrupted only by short periods of deregulation. Violation of contracts, price rises, price dumps, 'evasions', law suits are characteristic of today's American gas industry. The history of regulations in the U.S. gas industry is a nightmare other countries have fortunately been able to avoid. (orig.).

    Since 1998, The Pennsylvania State University successfully managed the Consortium for Premium Carbon Products from Coal (CPCPC), which was a vehicle for industry-driven research on the promotion, development, and transfer of innovative technologies on premium carbon products from coal to the U.S. industry. The CPCPC was an initiative led by Penn State, its cocharter member West Virginia University (WVU), and the U.S. Department of Energy's (DOE) National Energy Technology Laboratory (NETL), who also provided the base funding for the program, with Penn State responsible for consortium management. CPCPC began in 1998 under DOE Cooperative Agreement No. DE-FC26-98FT40350. This agreement ended November 2004 but the CPCPC activity continued under cooperative agreement No. DE-FC26-03NT41874, which started October 1, 2003 and ended December 31, 2010. The objective of the second agreement was to continue the successful operation of the CPCPC. The CPCPC enjoyed tremendous success with its organizational structure, which included Penn State and WVU as charter members, numerous industrial affiliate members, and strategic university affiliate members together with NETL, forming a vibrant and creative team for innovative research in the area of transforming coal to carbon products. The key aspect of CPCPC was its industry-led council that selected proposals submitted by CPCPC members to ensure CPCPC target areas had strong industrial support. CPCPC had 58 member companies and universities engaged over the 7-year period of this contract. Members were from 17 states and five countries outside of the U.S. During this period, the CPCPC Executive Council selected 46 projects for funding. DOE/CPCPC provided $3.9 million in funding or an average of $564,000 per year. The total project costs were $5.45 million with $1.5 million, or ~28% of the total, provided by the members as cost share. Total average project size was $118,000 with $85,900 provided by DOE/CPCPC.

    During the Industrial Revolution, class relations were defined largely through the struggle to control the terms of exchange in the market. Integrating aspects of economic and social history as well as industrial sociology, this book examines the sources of the perception of the market on the part of both capital and labour and the elaboration of their alternative market ideologies. Of particular import is the argument that working-class culture expressed a fundamental acceptance of the utility of the market, a point that is supported by a detailed analysis of the labour process, workplace bargaining, and early-nineteenth-century trade unionism. Nonetheless, the working class's definition of 'proper' market relations differed substantially from that of capitalists. Contents: Introduction; 1. Capital and credit; 2. The perception of the market and industrial policy; 3. Managerial capitalism; 4. Family, community, and the labor market; 5. Work and the ideology of the market; 6.

    Poland is rich in deposits of brown coal applicable for large-scale industry. These deposits are estimated at about 13.5.10 9 tons. In the near future, one-half of the electric power produced in Poland will be generated by power plants using brown coal. As a result, the yearly burden of the environment in Poland will amount to about 15.10 6 tons of ashes and slag, and about 0.79.10 6 tons of fly ash emitted into the atmosphere. Concentrations of radioactive elements in wastes following from the use of brown coal may in some cases be as much as 12 times higher that occuring from combustion products of lignite coal. Distribution of these wastes to the environment affects the population, through inhalation of fly-ashes, consumption of radioactively contaminated products and through living in dwellings constructed of building materials produced using industrial wastes. In order to determine the concentrations of 226 Ra, 232 Th and 40 K in brown coal and in products of its combustion, the method of identifying these elements through gamma-spectrometry has been prepared. Concentrations of 210 Pb and 210 Po will be determined using the method of electrodeposition on metallic silver, which has been tested in the laboratory. (author)

    This report examines current technologies and those likely to be used to produce cleaner coal and coal products, principally for use in power generation and metallurgical applications. Consideration is also given to coal production in the leading coal producing countries, both with developed and developing industries. A range of technologies are considered. These include the coal-based liquid fuel called coal water mixture (CWM) that may compete with diesel, the production of ultra-clean coal (UCC) and coal liquefaction which competes with oil and its products. Technologies for upgrading coal are considered, especially for low rank coals (LRC), since these have the potential to fill the gap generated by the increasing demand for coal that cannot be met by higher quality coals. Potential advantages and downsides of coal upgrading are outlined. Taking into account the environmental benefits of reduced pollution achieved through cleaner coal and reduced transport costs, as well as other positive aspects such as a predictable product leading to better boiler design, the advantages appear to be significant. The drying of low rank coals improves the energy productively released during combustion and may also be used as an adjunct or as part of other coal processing procedures. Coal washing technologies vary in different countries and the implications of this are outlined. Dry separation technologies, such as dry jigging and electrostatic separation, are also described. The demonstration of new technologies is key to their further development and demonstrations of various clean coal technologies are considered. A number of approaches to briquetting and pelletising are available and their use varies from country to country. Finally, developments in upgrading low rank coals are described in the leading coal producing countries. This is an area that is developing rapidly and in which there are significant corporate and state players. 81 refs., 32 figs., 3 tabs.

    Surveys were conducted of the trends of coal companies in the U.S. and Australia and of the lookout for new coal field development in Australia for the purpose of contributing to the stable supply of coal in the future. In the U.S., the coal industry has experienced serious changes in these ten years, and various corporations, such as Peabody, Arch Coal, CONSOL, and Kennecott have come to resort to drastic measures for their survival. In Australia, coal price is lower and contract terms are shorter with less demand for coal supply thanks to the economic crisis in Asia. As for demand for coal in Asia, on the other hand, it is deemed that in 2010 there will be a 41% increase over the 1995 level and that, therefore, coal field preservation and new field exploitation are necessary. Since production by strip mining in New South Wales State is to decrease in 2012 and after, it is expected that new projects will start only after 2012. Comprehensive development projects are going to be launched in the areas surrounding the Surat district, Queensland State, and therefore new projects will be easier to start in this region. Since the Surat coal is to be collected after a little stripping, it is expected that it will be able to compete with the Indonesian coal. (NEDO)

    Full Text Available DOI: 10.17014/ijog.v6i4.130Activated carbon made from Tanjung Tabalong coal was investigated its absorption capability to organic and inorganic elements in industrial waste. Coal was carbonized at low temperature of 600C to produce semicoke, and then was activated at temperature of 700C with activation time of 120 minutes with water steam flow. The absorption capability of activated carbon to chemical oxygen demand (COD was performed using 2.5 and 9.0 g activated carbon for 250 ml and 300 ml COD waste respectively. The agitation time of each experiment were 30, 60, and 90 minutes. Atomic absorption spectrophotometer (AAS was used to analyze the COD waste. The result shows that 2.5 g activated carbon could absorb COD waste ranging from 6.9-67.5 %, while the utilization of 9 g could absorb COD waste ranging from 88.9 - 100 %. The more activated carbon and the longer time of agitation used in this experiment, the more the absorption of COD waste.

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

    This study was initiated to provide information on the future potential industrial market for a cogeneration system consisting of a fluidized-bed coal combustor coupled to a gas-turbine (Brayton cycle) power system that uses air as the working fluid. In assessing the potential applications for the system, the process heat energy consumption by industry is identified, with special detail included on the six most energy-intensive industries. The potential impact on the nation's oil and natural gas consumption that would result from wide-spread utilization of coal for process heat is also estimated. The fraction of industrial process heat that the system could feasibly satisfy from a thermodynamic viewpoint is estimated, and the performance (potential fuel efficiency and heat/power ratio) of the atmospheric fluidized-bed gas-turbine system is calculated. Also treated are several specific case studies of industries in which the system could be incorporated. Major parameters are specified, and flow sheets are derived for systems that would satisfy the heat and power requirements of the process or industry. The overall fuel utilization efficiency, thermal power rating, and potential number of installations are specified for these case studies. The findings of the study indicate that there is a sizable potential market for the system, with over 1000 possible installations disclosed after reviewing only 8 specific industries from 6 major Standard Industrial Classification (SIC) groups. The potential displacement of oil and gas by coal in process heating is shown to be about 1.60 m/sup 3//sec (870,000 bbl/d) of oil and 4590 m/sup 3//sec (14.0 billion ft/sup 3//d) of natural gas for all industries combined. Continued development of the fluidized-bed coal combustor and power system is recommended so that this potential may be at least partially realized.

    We employ system dynamics method towards a coal-chemical industry district economy evolution model, using coal industry, the coal-chemical industry, their downstream industries, and the manufacture-related service industry. Moreover, we construct energy price and policy response scenarios based on Ordos’ management experience. The results show that the energy price slump had a negative impact on the overall economic development of the coal-chemical industry district, despite promoting non-resource industries. Furthermore, policies had different effects on the industry's output value and profit. In the long-term, developing alternative industries (AI) helps increase the industrial output value and profit. Decreasing value added tax (VAT) has immediate results and a distinctive effect on industrial short-term production value and profit, its long-term effect being limited. The effect of production limit (PL) on industrial profit is stronger than output value, and financial support (FS) is more conducive to improve the latter. However, coal mining and coal-chemical loan increases decrease the gross industrial profit level. Technology innovation (TI) has the best individual policy overall effect on production value and profits. Furthermore, the simultaneous implementation of PL, TI and AI can generate the synergy effect for each of them. And the simultaneous implementation of VAT and one or couple of other policies will generate the crowding-out effect both for VAT and other policies. - Highlights: • A system dynamics model of the coal-chemical industry district economy evolution in Ordos is constructed. • The impact of coal and oil prices slump on the output value and profit of each industry is revealed. • The differences in the effects especially cumulative effects of different response policies are clarified. • The crowding-out and synergy effects of policy implementation are analyzed.

    Full Text Available The coal measure gas sources of coal-derived gas fields in the Late Paleozoic China are the Lower Carboniferous Dishuiquan Formation, the Upper Carboniferous Batamayineishan Formation and Benxi Formation, the Lower Permian Taiyuan Formation and Shanxi Formation, and the Upper Permian Longtan Formation. The coal-derived gas accumulates in Ordovician, Carboniferous, Permian, and Paleocene reservoirs and are distributed in Ordos Basin, Bohai Bay Basin, Junggar Basin, and Sichuan Basin. There are 16 gas fields and 12 of them are large gas fields such as the Sulige large gas field which is China's largest reserve with the highest annual output. According to component and alkane carbon isotope data of 99 gas samples, they are distinguished to be coal-derived gas from coal-derived gas with δ13C2 > −28.5‰ and δ13C1 -δ13C2 -δ13C3 identification chart. The Late Paleozoic relative gas fields of coal measure are significant for the Chinese natural gas industry: proven natural gas geological reserves and annual output of them account for 1/3 in China, and the gas source of three significant large gas fields is coal-derived, which of five significant large gas fields supporting China to be a great gas producing country. The average reserves of the gas fields and the large gas fields formed from the late Paleozoic coal measure are 5.3 and 1.7 times that of the gas fields and the large gas fields in China.

    Full Text Available The article deals with the policies of EU countries towards coal power plants as well as practical steps taken by their governments. Coal power plants are widely considered to be environmentally harmful which confronts with environmental policies of the EU suggesting Europe-wide cuts of greenhouse gas emissions. Based on that assumption a number of EU countries such asBelgium,Austria,Portugal,Dania,Finland,SwedenandUKare striving to phase out coal power plants and achieved significant progress on this path replacing coal with other generation sources. On the other hand, other EU members are lagging behind as coal phase-out is not an urgent item of their political agenda. This situation is typical forIreland,Netherlands,Italy,Croatia,SloveniaandSlovakia. Domestic coal extracting industry can pose a significant hindering factor for a coal power plants phase-out and can effectively block the process. This is the case inBulgaria,Romania,Hungary,CzechRepublic,GreeceandPoland. ButGermany, which also has a well-developed coal industry, transforms its energy sector towards a green one cutting the share of coal in the generation mix. If this effort of the German government proves successful it will deliver a positive transformation model for other EU countries with a large share of coal in generation-mix due to domestic coal extraction industry. The analysis of the political and economic (both macro and micro processes leads to conclusion that there is no unity among EU member states in their approach towards coal fired power plants phase-out. This will allow for coal power plants to retain their market share in a short to medium term. But in the longer run one can expect a significant decrease of coal fired generation inEurope, even in the countries traditionally dependent on coal.

    Coal Tech Corp's mission is to develop, license & sell innovative, lowest cost, solid fuel fired power systems & total emission control processes using proprietary and patented technology for domestic and international markets. The present project 'DEVELOPMENT & TESTING OF INDUSTRIAL SCALE, COAL FIRED COMBUSTION SYSTEM, PHASE 3' on DOE Contract DE-AC22-91PC91162 was a key element in achieving this objective. The project consisted of five tasks that were divided into three phases. The first phase, 'Optimization of First Generation 20 MMBtu/hr Air-Cooled Slagging Coal Tech Combustor', consisted of three tasks, which are detailed in Appendix 'A' of this report. They were implemented in 1992 and 1993 at the first generation, 20 MMBtu/hour, combustor-boiler test site in Williamsport, PA. It consisted of substantial combustor modifications and coal-fired tests designed to improve the combustor's wall cooling, slag and ash management, automating of its operation, and correcting severe deficiencies in the coal feeding to the combustor. The need for these changes was indicated during the prior 900-hour test effort on this combustor that was conducted as part of the DOE Clean Coal Program. A combination of combustor changes, auxiliary equipment changes, sophisticated multi-dimensional combustion analysis, computer controlled automation, and series of single and double day shift tests totaling about 300 hours, either resolved these operational issues or indicated that further corrective changes were needed in the combustor design. The key result from both analyses and tests was that the combustor must be substantially lengthened to maximize combustion efficiency and sharply increase slag retention in the combustor. A measure of the success of these modifications was realized in the third phase of this project, consisting of task 5 entitled: 'Site Demonstration with the Second Generation 20 MMBtu/hr Air-Cooled Slagging Coal Tech

    Agnieszka Sorokowska

    Full Text Available Olfactory sensitivity varies between individuals. However, data regarding cross-cultural and inter-group differences are scarce. We compared the thresholds of odor detection of the traditional society of Tsimane' (native Amazonians of the Bolivian rainforest; n = 151 and people living in Dresden (Germany; n = 286 using "Sniffin' Sticks" threshold subtest. Tsimane' detected n-butanol at significantly lower concentrations than the German subjects. The distribution of thresholds of the Tsimane' was very specific, with 25% of Tsimane' obtaining better results in the olfactory test than any member of the German group. These data suggest that differences in olfactory sensitivity seem to be especially salient between industrialized and non-industrialized populations inhabiting different environmental conditions. We hypothesize that the possible sources of such differences are: (i the impact of pollution which impairs the olfactory abilities of people from industrialized countries; (ii better training of olfaction because of the higher importance of smell in traditional populations; (iii environmental pressures shaping olfactory abilities in these populations.

    Full Text Available This research aims to explore correlations between consumer-generated social media activity and the level of sales of German brands from the fast moving consumer goods industry. In particular, the objective was to examine whether there is a correlation between the number of brand mentions in social media and the sales of these products. The results indicate that the number of brand mentions and sales correlate positively in relation to products from the food and beverages category while this is not the case with respect to the non-food product category. Hence, marketers need to promote consumer-generated social media activity particularly for food and beverages.

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

    Full Text Available In the last century, the world has seen an acceleration of technological development in almost all the fields related to human life, leading to rapid improvement of living standards in most countries. Electricity industry is a basic economic branch, and is also a branch with high importance to the economy and social life of any country. This branch, which currently is the base of industrial, agricultural, transportation and telecommunications activities, and which characterizes the entire modern world civilization, began to develop only towards the late of the XXth century. Electricity is an energy form easily usable in production, household consumption, transport, telecommunications etc. It was the one that revolutionized manufacturing resources and equipment used in all fields. Electricity production worldwide has increased about 30 times since 1938. Coal maintained a vital role in the total energy sources, especially by ensuring price stability which is a major and indispensable factor for stability and further economic growth, and also by its distribution around the globe.

    The liquidation of waste dumps on the surface of mining enterprises and realization of measures by environment protection of air and aquatic basins are connected to the complex processing of mining mass. The main directions of utilization of mining rocks and coal wastes realized in Ukraine industry are: - filling of mines worked-out area by grouting solutions; - ceramic brick, porous filling materials and binding materials production; - road-making, construction of hydrostructures and industrial objects; - output of concrete items predominantly for using in mining conditions. The peculiarity of wastes using in above-mentioned fields is the possibility of their mass application in quantities commensurable with valumes of their yields. The experience of enterprises work which process mining rocks into building materials by burning method (ceramic brick, porous aggregates of concretes as aggloporite, expanded clay aggregate) has shown that unconstant and, as the rule, exceeding norms content of carbon and sulphur in the rock results to deterioration of products quality and technological factors of production. Unstability of carbon content in raw material makes the burning process hardly operated. Obtained products having residual carbon in the view of coke residue are often characterized by lower physical-mechanical characteristics. (orig./SR)

    Analyzing the chemical industry’s energy use is challenging because of the sector’s complexity and the prevailing uncertainty in energy use and production data. We develop an advanced bottom-up model (PIE-Plus) which encompasses the energy use of the 139 most important chemical processes. We apply this model in a case study to analyze the German basic chemical industry’s energy use and energy efficiency improvements in the period between 1995 and 2008. We compare our results with data from the German Energy Balances and with data published by the International Energy Agency (IEA). We find that our model covers 88% of the basic chemical industry’s total final energy use (including non-energy use) as reported in the German Energy Balances. The observed energy efficiency improvements range between 2.2 and 3.5% per year, i.e., they are on the higher side of the values typically reported in literature. Our results point to uncertainties in the basic chemical industry’s final energy use as reported in the energy statistics and the specific energy consumption values. More efforts are required to improve the quality of the national and international energy statistics to make them useable for reliable monitoring of energy efficiency improvements of the chemical industry. -- Highlights: ► An advanced model was developed to estimate German chemical industry’s energy use. ► For the base year (2000), model covers 88% of the sector’s total final energy use. ► Sector’s energy efficiency improved between 2.2 and 3.5%/yr between 1995 and 2008. ► Improved energy statistics are required for accurate monitoring of improvements.

    Australia and Canada are benefiting from a global increase in coal consumption, but face challenges regarding coal and coal export capacity. Coal is Australia's biggest export commodity, accounting for over 50 percent of world coking coal exports, with almost 75 percent of those exports destined for Asian markets, primarily Japan. However, the number of ships delayed at Australian ports hit a record of 223 bulk carriers in early 2010. Compared to Canada, Australia faces greater logistical issues getting coal into port and onto ships at its 9 loading terminals. Two of Canada's 3 major shipping terminals, Westshore and Neptune, have some additional capacity. Its third terminal, Ridley Island, has considerable potential to carry more coal. With 98 percent of all coal moved by rail in Australia, rail issues also hinder growth. A national approach to planning freight transport on both roads and rail is being developed. While infrastructure issues remain the single greatest barrier to export growth for Australia's coal sector, Canada's most immediate issues pertain to mine permitting and mine-site expansion. In 2009, Canada exported 28 million tonnes of coal, 90 percent of it metallurgical. With approximately 70 million tonnes of annual production, mostly in British Columbia and Alberta, coal remains the number one commodity in Canada carried by rails and shipped from ports. 1 fig.

    2017-06-01

    Full Text Available Acid mine drainage (AMD and mine tailing environments are well-characterized ecosystems known to be dominated by organisms involved in iron- and sulfur-cycling. Here we examined the microbiology of industrial soft coal slags that originate from alum leaching, an ecosystem distantly related to AMD environments. Our study involved geochemical analyses, bacterial community profiling, and shotgun metagenomics. The slags still contained high amounts of alum constituents (aluminum, sulfur, which mediated direct and indirect effects on bacterial community structure. Bacterial groups typically found in AMD systems and mine tailings were not present. Instead, the soft coal slags were dominated by uncharacterized groups of Acidobacteria (DA052 [subdivision 2], KF-JG30-18 [subdivision 13], Actinobacteria (TM214, Alphaproteobacteria (DA111, and Chloroflexi (JG37-AG-4, which have previously been detected primarily in peatlands and uranium waste piles. Shotgun metagenomics allowed us to reconstruct 13 high-quality Acidobacteria draft genomes, of which two genomes could be directly linked to dominating groups (DA052, KF-JG30-18 by recovered 16S rRNA gene sequences. Comparative genomics revealed broad carbon utilization capabilities for these two groups of elusive Acidobacteria, including polysaccharide breakdown (cellulose, xylan and the competence to metabolize C1 compounds (ribulose monophosphate pathway and lignin derivatives (dye-decolorizing peroxidases. Equipped with a broad range of efflux systems for metal cations and xenobiotics, DA052 and KF-JG30-18 may have a competitive advantage over other bacterial groups in this unique habitat.

  16. Influence of Environmentally Friendly and High-Efficiency Composite Additives on Pulverized Coal Combustion in Cement Industry

    Zhiyong Wang

    2016-01-01

    Full Text Available 4 kinds of chemical reagents and 3 kinds of industrial wastes were selected as burning additives for 2 kinds of coals in cement industry. The work focused on the replacement of partial chemical reagents by industrial wastes, which not only reduced the cost and took full advantage of industrial wastes, but also guaranteed the high combustion efficiency and removed the NOX and SO2 simultaneously. The experiments were carried out in DTF. The combustion residues were analyzed by SEM and XRD. The results showed that the burnout rate was increased after adding the additives; meanwhile, the NOX and SO2 release concentration were reduced, but the degree of action varied for different additives and coals. The substitute of chemical reagents by industrial wastes was very effective; overall, the cold-rolled iron oxide worked better than others; the particles surface was tougher and the peaks of crystalline phase were lower than raw coal, which indicated that the additives played good roles in combustion process.

    2014-01-01

    There are extensive governmental rent-seeking activities in safety supervision of the Chinese coal industry. The rents come from industry safety barriers, low resource taxes, and privilege policies for coalmining enterprises. The rent-seeking mechanism was analyzed using a model comprising dynamic games with incomplete information. The equilibrium results indicate that the probability of national supervision is influenced by penalties and bribery: there is negative correlation with penalties and positive correlation with bribery. The rent-seeking probability of a governmental safety supervision department is influenced by several factors, and positively correlates with the cost of national supervision. The probability of bribery of coalmining enterprises is influenced by several factors, and positively correlates with wages of governmental departments and a reasonable rent-seeking range. Reversed rent-seeking reduces the probability of bribery, but it's not worth recommending. Some recommendations are proposed. - Highlights: • We analyze rent-seeking mechanism for safety supervision in the coal industry. • A dynamic game with incomplete information for Chinese coal industry is built. • Reversed rent-seeking is proposed as a new rent-seeking form. • We analyze the selection probability of the three participants. • We give some policies about how to enhance safety supervision

    2012-11-01

    This study examines the lobbying strategies employed by the interest organizations of Germany's energy industries in the process leading up to the EU's Renewable Energy Directive. How did they lobby, and what does this reveal about their perceptions of power relations in the EU? This report focuses on the most controversial part of the Directive: legal prescriptions for support mechanisms to increase the production of renewable energy in Europe. The utilities and the renewables industries disagreed deeply, with the utilities industry favouring an EU-wide green certificate scheme, while the renewables industry pressed for national feed-in tariffs. Nine interest organizations representing these sectors, five German and four at the EU level, serve as cases in this study. Expectations as to lobbying behaviour based on the two theories/theory perspectives of liberal intergovernmentalism (LI) and multi-level governance (MLG) are formulated and tested in a most-likely case design. Result: observations are better described by the MLG perspective than by LI.(auth)

    Full Text Available According to the official data, Romania has more than 600 companies involved in the automotive industry, with more than 203,600 employees. However the automotive industry is facing a real problem when it comes to finding skilled work force. In the west part of the country, the unemployment rate is negative and companies are forced to find solutions for their lack of personnel. This study presents the solutions that were taken by Germany in order to solve the matter. A dual education system was implemented which combines trainings in a company with vocational education. This kind of system is practiced in countries such as: Germany, Austria, Switzerland and South Korea. As of 2005 young German people can learn one of 356 apprenticeship occupations through this program. In France, dual education has gained a lot of popularity since the 1990s. In order to gain more experience and have multilateral development, in Germany the students are also send to workshops run by guilds or chamber of commerce. The advantages of the dual training system are numerous and this program can help the industry by providing skilled workers with flexible qualifications, solution which may as well be suitable for the Romanian Automotive Industry.

  10. The effects of the German renewable energy sources Act (EEG) on market, technical and industrial development

    Since 1999, the German photovoltaic market has been growing rapidly. In 2003, more than 130 MWp PV systems were installed in Germany; in 2004, more than 200 MWp are expected to be installed additionally. The main reason for this impressive market success has been the market stimulation policy of the German government. In January 1999, the 100.000 Roofs Programme for photovoltaic systems had started, offering interest-reduced loans for PV systems. In April 2000, it was backed by the Renewable Energy Sources Act (EEG), which considerably increased the feed-in tariff to 99 Pfennig (0.51 euros) per kWh. Since then, the PV market has boomed. In 2003, the 100,000 Roofs Programme (HTRP) ended successfully, after loans for more than 300 MWp PV systems had been granted. In order to fill the gap created by the termination of the programme, the government decided to increase the feed-in tariff provided by the EEG. Since January 2004, grid-connected PV systems on roofs and facades receive a tariff between 0,540 euros and 0,624 euros per kWh over 20 years. This improvement of the EEG further increased the interest in photovoltaics. The growth rate of the photovoltaic market, exceeding 50% in 2004, has led to the demand being higher than the available supply of PV systems. (author)

  11. The economic case for industrial application of low-rank coal technology

    Irwin, W.

    1991-01-01

    The World Coal Institute estimates coal should overtake oil as the world's largest source of primary energy by the turn of the century. Current world coal production of 3.6 billion tons in 1990 is predicted to rise to 4 billion tons by the year 2000. It is conceded that a major environmental problem with burning coal is the so-called greenhouse effect. The question is how do you use the new technologies that have been developed which now allow coal to be burned with minimum damage to the environment. Despite their technical merits, acceptance of these new technologies is slow because they appear uncompetitive when compared with historic energy costs. Unless economic comparisons include some form of environmental evaluation, this issue will continue to be a barrier to progress. To avoid stagnation and provide the necessary incentive for implementing badly needed change, structural changes in energy economics need to be made which take into account the environmental cost element of these emerging new technologies. The paper discusses coal trade and quality and then describes the three main areas of development of clean coal technologies: coal preparation, combustion, and flue gas treatment

    In Europe, international division is in progress as the result of market internationalization, and the coal market is experiencing an increasingly intensive competition in the storm of deregulation. The coal industry of Britain is away from a crisis for the time being, thanks to a new 5-year contract concluded with the electric utilities who are the primary purchasers, but it has to compete with imported coal and natural gas. The industry is also hit by the control imposed on the development of new opencast coal mines. Production is on the decline in the German coal market, which is one the largest in Western Europe, due to reduced subsidies, unfavorable geological conditions, lowered price, etc. The German coal industry is positively striving to exploit coal mines overseas and to export coal mining technologies. In Spain and France, the coal industry is forced to shrink and, in France, there is a plan to terminate coal mining completely in 2005. In Poland, the introduction of market economy has resulted in the influx of low-price coal from Russia etc., and all the Polish mines are now in the red. Its joining the European Union in the near future will further increase the pressure from other nations. It is learned that in Britain, Germany, etc., coal businesses are accelerating their transfer of technology to developing countries and are positively strengthening their presence abroad. (NEDO)

    The DKVG (German nuclear power plant insurance association), founded in 1957, has 104 member insurance companies, all registered in the Federal Repbulic of Germany. At present property insurance amounts to 1.5 billion DM, and liability insurance to 200 million DM. The overall damage ratio was 15.4 (1988: 5.9) percent, whereby home business remained claim-free in 1989. The relatively low damage ratio of 15 percent should not deviate from the fact that nuclear insurers always have to reckon with large damage. At the moment it would cost them a maximum gross sum of 1.7 billion DM (property and liability insurance); on account of DKVG 685 million DM. (orig./HP) [de

    Turnheim, Bruno; Geels, Frank W.

    2012-01-01

    This paper investigates a neglected aspect of the transitions literature: the destabilisation of existing regimes and industries. It presents an analytical perspective that integrates four existing views on destabilisation and conceptualizes the process as a multi-dimensional and enacted phenomenon involving technical, economic, political, and cultural processes. This perspective is illustrated with two historical cases of the British coal industry (1913–1967, 1967–1997). These cases are also used to articulate five lessons regarding the overall destabilisation process and five lessons regarding the economic and socio-political environments of industries. The conclusion section translates the historical lessons into insights with relevance for the contemporary challenge of climate change and transitions to low-carbon energy systems. - Highlights: ► We investigate the destabilisation of existing regimes and industries. ► We conceptualise destabilisation as a multi-dimensional and enacted phenomenon. ► We mobilise two historical cases of the British coal industry. ► We develop ten original lessons on destabilisation. ► We provide insights of relevance to transitions to low-carbon energy systems.

    A system of optimization computations of five year plans is set forth which was developed over a number of years at the Central Scientific Research Institute of Economics and Scientific-Technical Information of the Coal Industry. Basic principles of design and methodological approaches are given which were used in development of the systemas well as levels of administration and information links between them. The report analyzes the characteristics of problems of planning which arise at different stages of formation of the five year plans and discusses possibilities of taking into account these characteristics in optimized models. Economic formulations of problems of optimization of five year plans are given as applied to two levels of administration: at the branch level and at the level of production associations. Economic-mathematical models of optimization of five year plans are developed for each of the levels and their characteristic features described. The primary methodological principles, on the basis of which optimization models were developed are examined. An economic-mathematical model with continuous variables was developed for the branch level of planning. Volumes of recovery according to a group of shafts in the stage of normal operation (stable group) of each production enterprise are adopted as model variables. A system of limitations which includes limitations on volumes and distinguishable resources is formulated. The minimum of operating expenses, minimum of capital investments and maximum of recovery volumes for the planned period can be used as the optimization criteria. An economic-mathematical model which uses integral variable was developed for the production association level.

    The Canadian coal and oil sands industries operate in one of the most stringent environmental regulatory frameworks found in the world. The purpose of the strict regulations is to ensure that Canadian energy resources are developed safely, responsibly and efficiently. Their primary objectives involve the protection of water supplies and aquatic life. This article discussed how suppliers are helping the coal and oil sands industries address environmental concerns. Several examples were provided. In terms of water protection and management, EBA Engineering Consultants has helped mining companies comply with strict environmental regulations and has assisted them in obtaining the necessary permits and establishing monitoring programs. In terms of containment, the Layfield Group's silt and sediment control products has helped prevent fine soil particles from running off into and clouding local water courses. In terms of land reclamation and remediation, IW Kuhn Environmental Ltd., has provided soil remediation services, including re-vegetation using hydroseeding which involves the sowing of seeds with a hosed jet of water. This article also discussed the many green technology products that have been developed and commercialized by EarthRenew for application in coal and oil sands projects. Their patented waste renew facilities can process and cook manures, biosolids or green wastes into organic fertilizers that could be used in land repair applications. 5 figs.

    The formula - stability through diversity - stands for a promising approach to energy policy. Germany will be phasing out nuclear energy by 2022 and giving a big push to renewables as a substitute. That changes the electricity mix. In this setting, lignite becomes more valuable as base load energy. Any look at the history of technology shows that, in the competition to find good solutions, experience proves that diversity is generated, and that means stability. In the energy sector, no one solution will determine the future, but many different technologies will co-exist in a pattern that is increasingly networked and integrated. The background here is a combination of nature circumstances, the wishes of consumers and, of course, the technical potential and availability of raw materials. There is no sign that coal, which is so abundantly available and competitive worldwide, will be excluded from the energy mix any time soon. The figures prove the contrary. The dynamism of world coal consumption speaks an unequivocal language. Germany, with its lignite, has a valuable natural resource which will be available for a long time to come. Germany's energy-policy aim should be to make use of the strengths of domestic lignite, strengths like security of supply and affordability, while working on minimising CO{sub 2} emissions, in particular through increases in efficiency and, in the long run, through CCS. Indispensable for this are the underlying production conditions. At the start, I had a word of thanks for our many partners for their good cooperation. We go on relying on your support. Specifically, we hope that the lignite industry, like other sectors will go on being appreciated for the benefits that it brings, and that no additional burdens are envisaged that might impair its competitiveness. It is our task in the lignite industry to further develop the potential of lignite with our wealth of ideas and fact-driven work. The good of today thus make a better

    Environmental protection policies in the automobile market were not implemented until the motorisation of the masses in the 1960s caused an increasing environmental burden. The rising air pollution was considered a latent danger for humans, animals and plants. In the years up to 1985 the EU passed several regulations to limit the mass pollutants CO, CxHy and NOx. Germany was the first EU-member nation to also be concerned with lead in gasoline, passing reduction regulations as early as in 1971. In 1986, several EU-member nations implemented the supply of unleaded gasoline. This decision was predominantly based on information about widespread forest damage. The reduction of lead emissions due to these regulations could be verified in different environmental systems. An example of this was the decline of atmospheric lead concentrations and human blood lead levels in Germany. The German mineral oil and automobile markets were also affected. The price trend of unleaded fuel was heavily influenced by tax incentives which benefited not only the gasoline traders but also the consumers. With regard to the distribution system, the market positions particularly of the medium-sized traders and the independent importers were weakened. In the automobile market, favourable terms of competition were experienced by producers who had already gained experience with catalyst systems in the U.S.-market. The gasoline lead content regulations had no effects on further economic indicators, except for competition. (orig.)

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

    Information and communication technologies (ICT) lay the basis for the information society and have therefore a daily influence on almost everybody. This involves certain requirements regarding the purpose of a sustainable development as for example energy use, careful use of resources, and global compliance with social standards. However, ICT applications and their integration into business processes as well as daily private life also offer enormous potential for shaping sustainable development. Based on this realization, active companies and their associations are to play an important role in promoting new approaches for Sustainability. To this reason the German ICT-Association BITKOM together with some of the most active players in this field founded a new workgroup for International Environmental Policy and Sustainability. Main targets are the communication of an orientation towards sustainability within the own branch as well as the usage of ICT-products and services to enable sustainable development on a society basis. This covers political activities, publication of guidelines and brochures as well as the discussion of new approaches with scientists and NGOs. By critically questioning the approach within the own branch the process of a transparent communication shall be initiated, by which everybody will be able to contribute his specific part to the whole ''sustainability-puzzle''.

    1996-01-01

    Reasons to look for an alternative crosslinking system avoiding sulphur curing was the restrictive policy of the German Health Authorities concerning nitrosamines. It was concluded that radiation curing offers further advantages . By avoiding the accelerators, type IV allergy is excluded, cytotoxicity is minimised to a very low level, films have better clarity and when thoroughly leached higher electrical resistance. Treatment of waste give no SO sub 2 emissions by burning, no Zinc in the ashes and possibly better microbial degradation. A development was carried out to irradiate natural latex by electron beam with a Dynamitron equipment. It was found trimethylolpropanetrimethacrylate to be a suitable sensitizer. Because of to high prices this development was interrupted. For future application trials and efforts to introduce RVNRL in the market gamma ray radiated natural latex either from Batan, Indonesia or MINT, Malaysia are used. Mainly dipped goods were produce, but radiated natural latex has shown good results in other processes. During discussions with customers it has proved necessary to establish specifications for RVNRL. A serious problem using natural latex for the production of medical devices is the type I allergy. Attempts are made to dip surgical gloves, leach them thoroughly and control extractable proteins were reduced to the very low level of 6.5 μg/g. Out of 18 patients sensitive to natural latex protein wearing gloves made from RVNRL only six have shown a positive response. That means RVNRL could help to solve the protein allergy problem. Further developments on this line are scheduled

  12. Economic and technical facts and developments in the field of energy in German industry

    Rolshoven, H.

    1979-07-01

    A review of the energy situation with regard to energy management and technological developments in Germany is presented. It is observed that the industrial consumption of energy is considerably lower than that of households and authorities of all kinds, leading to the conclusion that the greatest scope for saving on energy raw materials, particularly oil, lies in the area of households and small consumption areas. Some data and measures for conservation in the five most energy-intensive industries are briefly discussed. Examples of the national use of energy are given. (MCW)

  14. Quantitative applications of gamma densitometry in the coal industry: a critique

    International Nuclear Information System (INIS)

    Shea, P.; Sher, R.; Gozani, T.

    1982-01-01

    This paper discusses the use of gamma densitometry to quantitatively assay bulk samples of coal on a continuous basis. Devices using these principles to determine mass flows are on the market, and work is progressing in several countries on instruments to determine ash content. The theoretical limits of applicability and inherent assumptions of these techniques are discussed, primarily as applied to dry bulk coal, but with some discussion of the more complicated problems of slurried coal. Gamma rays are generated by sources, usually a single radioactive element. These have several advantages over XRF, the main one being that no power is required to generate gammas. However, there are a limited number of gamma sources with useful energies, long enough half-lives to be economically useful, and clean spectra (that is, relatively few energies emitted by the source in question). Gamma densitometry measurements by single and multiple-energy transmission and backscatter measurements are discussed. A general formalism for analyzing multiple-energy systems is presented. While multi-energy systems can, in principle, pick out as many groups of elements as energies used, the matrices involved are ill-conditioned and thus require accurate measures of count rate (i.e., long counting times or high source intensities) to achieve acceptable errors. Changes in coal composition and profile of coal on a belt were also seen to be important sources of error. Transmission measurements are more amenable to analysis than backscatter, which are essentially transmission measurements made on a distributed source. In addition, transmission measurements are not restricted to low energy gamma sources, and can survey the entire bulk of coal rather than just the upper portion. The special problems of slurried coal measurements are briefly discussed

  15. Engineering Philosophy: Theories of Technology, German Idealism, and Social Order in High-Industrial Germany.

    Science.gov (United States)

    Voskuhl, Adelheid

    During the so-called "Second Industrial Revolution," engineers were constituting themselves as a new social and professional group, and found themselves in often fierce competition with existing elites-the military, the nobility, and educated bourgeois mandarins-whose roots went back to medieval and early modern pre-industrial social orders. During that same time, engineers also discovered the discipline of philosophy: as a means to express their intellectual and social agendas, and to theorize technology and its relationship to art, history, culture, philosophy, and the state. This article analyzes engineers' own philosophical writings about technology as well as the institutions in which they composed them in 1910s and 1920s Germany. It emphasizes engineers' contributions to well-known discourses founded by canonical philosophers, the role of preindustrial economies and their imagination in such philosophies, and the role of both the history and the philosophy of technology in engineers' desire for upward social mobility.

  16. Aromatic raw materials from coal

    Energy Technology Data Exchange (ETDEWEB)

    Collin, G

    1982-06-01

    Liquid byproducts of coal carbonization meet some 25% of the world demand for aromatic chemicals, currently at approx. 30 million t/a, in particular 15% of the demand for benzene and over 95% of the demand for condensed aromatics and heteroaromatics. Industrial processing of the aromatic byproducts of coal pressure gasification is carried out to only a minor extent. Other methods that may be employed in future to obtain carbochemical aromatic compounds are solvolysis and supercritical gas extraction, the catalytic liquid-phase hydrogenation and hydropyrolysis of coal, which also permit recovery of benzene and homologues, phenols, and condensed and partially hydrogenated aromatics, and the synthesis of aromatics using methanol as the key compound. As with the present means of obtaining aromatic chemicals from coal, the processes that may in future be applied on an industrial scale to obtain pure aromatics will only be economically feasible if linked with the manufacture of other mass products and combined with the present production of carbochemical aromatics.

    2013-01-01

    The last major advance in gas content measurement for coal seams was the introduction of the quick crush technique in the early 1990s. This is a laboratory test method that has proven very reliable over the years. Recent laboratory testing using a portable quick crushing device, known as the portable gas content analyser, has produced consistent gas content results for a set of core samples obtained from a single borehole that intersected four coal seams. The retained gas content values obtained for the seams show the same increasing gas content pattern and gas composition change with depth as the standard quick crush technique. Use of the portable gas content analyser provides the opportunity to produce rapid, reliable gas content measurement of coal that could be developed for assessing gas compliance cores and outburst-prone conditions at a mine site.

    The report deals mainly with coal consumption, but also gives some information about technology, environmental aspects and markets. Data have been collected by questionnaires or via telephone. The use of steam coal for heating was 0.8 Mtons (down 20% from 1994). Cogeneration plants were the main users. Taxes and environmental reasons cause a reduction of the coal use that will probably continue the next years. Use of steam coal in industry has been constant at a level of 0.7 Mtons. The import of metallurgical coal rests constant at a level of 1.6 Mtons. 1.2 Mtons of coke was produced, and 0.3 Mtons imported. The PFBC-plant at Vaertan, Stockholm used 0.13 Mtons of coal, while some coal fired power plants have been converted to peat and wood fuels. The average price of steam coal imported to Sweden in 1995 was 333 SEK/ton, 6% higher than in 1994. The contract prices for delivery 1996 are about the same as at the end of 1995. All cogeneration plants have some sort of SO 2 removal system, mostly wet-dry. The largest plant, at Vaesteraas, has recently invested in a SCR system for NO x removal. Most other plants are using low NO x burners or SNCR systems, based on ammonia or urea, which reduce the emissions 50 - 70%. Some statistic about the world coal market is also given in the report

    2017-09-01

    Full Text Available The urgency of the issue of reclamation of disturbed lands is due to the fact that coal mining by both open and underground methods is inevitably accompanied by exclusion from economic circulation and violation of lands for various purposes, by changing the terrain and forming an industrial landscape. The article contains information on the volumes of disturbance and reclamation of lands in the coal industry In the article the directions of reclamation and applied technologies, domestic developments and foreign experience are considered. It was noted that the priority areas for reclamation of disturbed lands in the coal industry are: agricultural, forestry and sanitary-hygienic. It is noted that the quality of the recultivated areas is not always at the proper level, which creates dif culties in their subsequent use. The main reasons for the low quality of reclamation are the lack of the necessary amount of initial data on the composition and properties of soil and rock mass of the dumps at the development stage of the reclamation projects, the lack of special technical means for performing remediation works at a high level, the lack of a landscape approach to the restoration of disturbed areas. Measures to prevent spontaneous combustion of rock dumps are laid in projects and are not implemented in practice in full, which leads to the occurrence of res. Two new developments in the eld of reclamation are presented: the microbiological method developed by MNIIECO TEK JSC, and the method for restoring the biological productivity of disturbed lands, proposed by the Scienti c Research Institute of Agricultural Problems of Khakassia SB RAAS. Identi ed problem issues in the eld of reclamation and a list of measures to improve the state of protection of land resources. In the article it is shown that in order to improve the state in the sphere of land resources protection in the coal industry, it is necessary to improve the applied mining technologies

  4. Environmental impact of coal industry and thermal power plants in India.

    Science.gov (United States)

    Mishra, U C

    2004-01-01

    Coal is the only natural resource and fossil fuel available in abundance in India. Consequently, it is used widely as a thermal energy source and also as fuel for thermal power plants producing electricity. India has about 90,000 MW installed capacity for electricity generation, of which more than 70% is produced by coal-based thermal power plants. Hydro-electricity contributes about 25%, and the remaining is mostly from nuclear power plants (NPPs). The problems associated with the use of coal are low calorific value and very high ash content. The ash content is as high as 55-60%, with an average value of about 35-40%. Further, most of the coal is located in the eastern parts of the country and requires transportation over long distances, mostly by trains, which run on diesel. About 70% oil is imported and is a big drain on India's hard currency. In the foreseeable future, there is no other option likely to be available, as the nuclear power programme envisages installing 20,000 MWe by the year 2020, when it will still be around 5% of the installed capacity. Hence, attempts are being made to reduce the adverse environmental and ecological impact of coal-fired power plants. The installed electricity generating capacity has to increase very rapidly (at present around 8-10% per annum), as India has one of the lowest per capita electricity consumptions. Therefore, the problems for the future are formidable from ecological, radio-ecological and pollution viewpoints. A similar situation exists in many developing countries of the region, including the People's Republic of China, where coal is used extensively. The paper highlights some of these problems with the data generated in the author's laboratory and gives a brief description of the solutions being attempted. The extent of global warming in this century will be determined by how developing countries like India manage their energy generation plans. Some of the recommendations have been implemented for new plants

    This study was performed to investigate the frequency of bladder cancer in patients with an occupational history such as underground hard coal mining and/or painting after the structural change in the local industry. A total of 206 patients with bladder cancer and 207 controls were enlisted regarding occupational and nonoccupational bladder cancer risk factors by questionnaire. The phase II enzymes N-acetyltransferase 2 (NAT2), glutathione S-transferases M1 (GSTM1), and T1 (GSTT1) and the single nucleotide polymorphism (SNP) rs11892031[A/C] reported to be associated with bladder cancer in genome-wide association studies were genotyped. The bladder cancer risk in varnishers and underground hard coal miners was increased as previously shown in a study in this area performed in the 1980s. The occupation of a car mechanic was associated with a significantly elevated bladder cancer risk and higher in the case of underground hard coal miners even though the mine was closed in 1987. The frequency of GSTM1 negative genotype was comparable in cases and controls (53% versus 54%). In the case of NAT2, the slow NAT2 genotype was more frequent (62% versus 58%) and ultra-slow NAT2 genotype (NAT2*6A and/or *7B alleles only) was 23% versus 15%. An occupational history of a varnisher or an underground hard coal miner remains a risk factor for bladder cancer occurrence. Data indicate that in the case of bladder cancer, GSTM1 is a susceptibility factor related to environmental and/or occupational exposure.

    Chemical and petrographic analysis was conducted on coals from the Anadyrya and Bukhti Ugol'noi deposits. Characteristics of the most prevalent type of vitrinite coals in both regions are presented here. Anadyrya coals belong to a transitional phase between brown coal and long flame. Ultravitrinite coals predominate. Gas coals from Bukti Ugol'noi have a higher carbon content than Anadyrya coals. They also have a higher hydrogen content and yield of initial resin. In several cases there was also a higher yield of volatile substances. Chukotka coals are characterized by a 10 percent higher initial resin yield than equally coalified Donetsk coals, other indicators were equal to those of Donetsk coals. Because of this, Chukotka coals are suitable for fuel in power plants and as raw materials in the chemical industry. (15 refs.) (In Russian)

    The analysis on the economic factor environment and the German environmental industry on international competition is faced to methodological limits, since the environmental industry does not present itself as an homogeneous sector. The study is organized in the following chapters: introduction - the importance of environmental industry; classification of environmental and climate protection industry; productivity volume and production structure; international competition for potential environmental protection products; environmental protection industry and innovative performance. Integrated environmental solutions are of increasing significance, avoiding emissions and products and production process from beginning on. All known forecast indicate an expansive market development. In addition the rising prices for crude oil may push the search for innovative solutions to substitute fossil energy sources. The environmental industry should look for globally transferable solutions in order to promote global sustainable growth.

    For the purpose of working out a comprehensive master plan for application of the coal utilization system, the paper surveyed and studied the coal utilization system in terms of environmental measures and efficiency improvement in the utilization of coal. As a result of the discussion with NEDO and the National Planning Committee of China, Liaoning Province (the whole China) and Shenyang City were selected as a model area and a model city for the survey and study. As energy conservation measures taken in the former, desirable are intensifying/capacity-increase of boilers, kilns, etc. and adoption of new-type/high-efficient equipment. Also expected are reinforcement of combustion control and improvement of efficiency by using coal preparation, industrial use coal briquette, etc. Measures taken in the latter are the same as those taken in the whole China. As SOx reduction measures for Liaoning Province, desirable is installation of dry-type desulfurization equipment and simple desulfurization equipment. As dust prevention measures for it, desirable is installation of electrostatic precipitators or high-functional bag filters. SOx reduction measures for Shenyang City are the same as those taken in the whole China. SOx can be reduced by using coal-prepared low-sulfur coal and industrial use coal briquette added with desulfurizing agent. 88 figs., 163 tabs.

    The challenge of sustainable development in the coal mining industry consists of continuous guarantee of the aims of economic viability, security of supply, compatibility with the environment and social interests. Sustainable development of the coal industry is thus a complex large system, which consists of four partial systems, viz. economy, society, environment and resources of the coal fields. It is based on the coordinated development of these four partial systems. To investigate quantitatively the state of the coal industry in China and the future trends for its sustainable development, an evaluation indicator system consisting of target, criterion and indicator level was formulated in this contribution. According to the structure of the indicator system two evaluation models were developed, viz. fuzzy model based on the AHP method (AHP = Analytical Hierarchy Process) and a model with the aid of main component analysis. With regard to the historical data of the indicators the sustainable development of the coal industry in China was evaluated with the aid of the development models. (orig.)

    2012-01-01

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

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

    1977-01-01

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

However the field of activity of such enterprises is a priority for national economy, and difficult interchangeability of energy raw material resources demands from the state and the coal enterprises of development within realization of complete branch ecological-economic policy of the economic mechanism of stimulation of ecologically sustainable development of the coal complex. In the conditions of an economic crisis, threat of world recession and external economic pressure upon the forefront there are two priority economic tasks: maintaining economic and social stability and promote economic growth of the Russian economy and its regions. Along with attempts to stabilize the preserved and newly opened businesses, and really putting their place in the market economy, it is necessary to overcome the whole complex of socio-economic and environmental impacts of restructuring. The neutralization of the negative environmental impact of the closure of coal enterprises, as well as warning of emerging environmental hazards require large material costs. To reduce costs requires a comprehensive, scientifically sound approach to solving this global problem. Significant reserve to reduce the negative impact of ecological consequences of liquidation of mines on the environment is the task of the use of related natural resources, which are currently the sources of pollution of the biosphere.

    Liquefaction of coal is not profitable in West Germany and will not be so far some time to coal. This is true for West German and imported coal. The result may be improved but not changed by combined conversion of coal and top residues of distilleries. These are the main statements of a study carried out by Messrs. Veba Oel AG, Gelsenkirchen, on behalf of the Federal Minister for Research and Technology. The results of the study are presented in 20 volumes.

    2018-01-01

    Full Text Available The removal of reactive dyes on modified coal fly ash has been investigated during a series of batch adsorption experiments. Physical characteristics of modified coal fly ash was characterized by Brunauer Emmett Teller (BET surface area analysis, X-ray powder diffraction (XRD, Fourier transform infrared spectrophotometer (FT-IR, and scanning electron microscope (SEM. The effects of operational parameters such as initial dye concentration (50–200 mg/L, solution pH (4–10 and adsorbent dosage (50–200 mg/L were studied. The adsorption experiments indicated that modified coal fly ash was effective in removing of Remazol Blue. The percentage removal of dyes increased while the modified fly ash dosage increased. The percentage removal of dyes increased with decreased initial concentration of the dye and also increased with amount of adsorbent used. The optimum of removal of dyes was found to be 94% at initial dye concentration 50 g/mL, modified fly ash dosage 250 g/mL, and pH of 2.0.

    The precautionary measures principle and the polluter pays principle in brown coal mining are discussed. Ground water subsidence and landscape destruction are local or regional problems and thus easily detectable. If damage cannot be avoided, its authors are known and will pay. In spite of all this, the German brown coal industry is well able to compete on the world market with others who don't care about the environmental damage they may cause. (orig./HS)) [de

    Spontaneous and industrially caused subsurface coal fires are worldwide disasters that destroy coal resources, cause air pollution and emit a large amount of green house gases. Especially in developing countries, such as China, India and Malaysia, this problem has intensified over the last 15 years. In China alone, 10 to 20 million tons of coal are believed to be lost in uncontrolled coal fires. The cooperation of developing countries and industrialized countries is needed to enforce internationally concerted approaches and political attention towards the problem. The Clean Development Mechanism (CDM) under the framework of the Kyoto Protocol may provide an international stage for financial investment needed to fight the disastrous situation. A Sino-German research project for coal fire exploration, monitoring and extinction applied several geophysical approaches in order to estimate the annual baseline especially of CO2 emissions from near subsurface coal fires. As a result of this project, we present verifiable methodologies that may be used in the CDM framework to estimate the amount of CO2 emissions from near subsurface coal fires. We developed three possibilities to approach the estimation based on (1) thermal energy release, (2) geological and geometrical determinations as well as (3) direct gas measurement. The studies involve the investigation of the physical property changes of the coal seam and bedrock during different burning stages of a underground coal fire. Various geophysical monitoring methods were applied from near surface to determine the coal volume, fire propagation, temperature anomalies, etc.

    The report deals with the use of coal and coke during 1996. Some information about techniques, environmental questions and markets are also given. Data have been collected by questionnaires to major users and by telephone to minor users. Preliminary statistical data from SCB have also been used. The use of steam coal for heating purposes during 1996 was 1,2 mill tons and 50% higher than in 1995. The increase is probably temporary and due to high prices of electricity because of lack of water power. The co-generation plants were the main users of coal. The minor plants have increased their use of forest fuels. Probably the use of steam coal will go down in the immediate years both in the heat generating and the co-generation plants. During the top year 1987 coal was used in 18 hotwater plants and 11 co-generation plants. 1996 these figures are 3 and 12. Taxes and environmental reasons explain this trend. The use of steam coal in the industry has been constant at the level 700 000 tons. This level is supposed to be constant or to vary with business cycles. The import of metallurgical coal in 1996 was 1,6 mill tons like the year before. 1,2 mill tons coke were produced. The coke consumption in the industry was 1,5 mill tons. 0,3 mill tons of coke were imported. The average price of steam coal imported in Sweden in 1996 was 340 SEK/ton or 2% higher than in 1995. For the world, the average import price was 51,5 USD/ton, nearly the same as the year before. The contract prices for delivery during 1997 are about equal as the end of 1996. All Swedish plants meet their emission limits of dust, SO 2 and NO x given by county administrations or concession boards

  18. Fuel oil from low-temperature carbonization of coal

    Energy Technology Data Exchange (ETDEWEB)

    Thau, A

    1941-01-01

    A review has been given of German developments during the last 20 years. Four methods for the low-temperature carbonization of coal have been developed to the industrial stage; two involving the use of externally heated, intermittent, metallic chamber ovens; and two employing the principle of internal heating by means of a current of gas. Tar from externally heated retorts can be used directly as fuel oil, but that from internally heated retorts requires further treatment. In order to extend the range of coals available for low-temperature carbonization, and to economize metals, an externally heated type of retort constructed of ceramic material has been developed to the industrial stage by T. An excellent coke and a tar that can be used directly as fuel oil are obtained. The properties of the tar obtained from Upper Silesian coal are briefly summarized.

    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

    The first industrial-scale CO 2 capture plant in China has been demonstrated at Huaneng Beijing power plant has shown that this technology is a good option for the capture of CO 2 produced by commercial coal-fired power plants. The commissioning and industrial tests are introduced in this paper. The tests show that in the early stages of the passivation phase, the concentration variations of amine, anti-oxidant and Fe 3+ are in the normal range, and the main parameters achieve the design value. The efficiency of the CO 2 capture was about 80-85%, and by the end of January 2009 about 900 tons of CO 2 (99.7%) have been captured. The equipment investment and consumptive costs, including steam, power, solution and others, have been analyzed. The results show: the cost of the absorber and the stripper account for about 50% of main equipment; the consumptive cost is about 25.3 US$ per metric tons of CO 2 , of which the steam requirement accounts for about 55%; the COE increased by 0.02 US$/kW h and the electricity purchase price increased by 29%.

    The report deals with the use of coal and coke in Sweden during 1994. Some information about technology, environmental questions and markets are also given. Data have been collected by questionnaires to major users and by telephone to minor users. Preliminary statistical data from Statistics Sweden have also been used.The use of steam coal for heating purposes has been unchanged during 1994 at a level of 1 Mtons. The production in the cogeneration plants has been constant, but has increased for electricity production. The minor plants have increased their use of forest fuels. The use of steam coal will probably go down in the next years both for heat and cogeneration plants. During the top year 1987 coal was used in 18 hot water and 11 cogeneration plants. 1994 these figures are 3 and 12. Taxes and environmental reasons explain this trend. The use of steam coal in industry has been constant at the level 0.7 Mtons. The import of metallurgical coal in 1993 was 1.6 Mtons, like 1992. Import of 0.3 Mtons of coke gives the total consumption of coke in industry as 1.5 Mtons. the average price of steam coal imported to Sweden was 317 SEK/ton, 3% higher than 1993. All Swedish plants meet their emission limit of dust, SO 2 and NO x as given by county administrations or concession boards. The cogeneration plants all have some SO 2 removal system. The biggest cogeneration plant (Vaesteraas) has recently invested in a SCR NO x cleaning system. Most other plants use low NO x burners or SNR injection systems based on ammonia or urea. 2 figs, 13 tabs

  6. Ventilation air methane destruction - the new challenge to the underground coal mining industry

    International Nuclear Information System (INIS)

    Clarke, Michael; Seddon, Duncan

    2012-01-01

    With the advent of 'Carbon Taxes' the carbon footprint of coal has become an economic as well as an environmental issue and the emission of methane in mine out- bye air as ventilation air methane (VAM) is a pending liability. As well as being economic and environmental concerns, VAM and VAM management have safety, social licence and operational factors that must also be addressed. The need to mitigate (oxidise) methane to produce carbon dioxide and water vapour (VAM destruction) and thus lower the Greenhouse footprint is coming to be seen as a necessary mining activity. However, there are several key issues to be addressed with present technology using high temperature (1000°C) thermal oxidisers. Emerging technology may involve a catalytic approach. This technology aims to lower the oxidation temperature and produce a more efficient combustion process. Several systems (based on both precious metals and transition metals) have been shown to operate below 400°C. An ultimate solution would be oxidation at ambient temperature, which is clearly demonstrated by the enzyme methane mono-oxygenase (MMO) which oxidises methane to methanol. However, the rate of oxidation at ambient temperature is too low and the structure of the bio-reactors required would be very large. The challenge is to marry the natural oxidation with modern catalytic approaches and achieve high rates of methane oxidation, in compact equipment, well below the methane auto-ignition temperature.

    Recent research has identified regional variation of personality traits within countries but we know little about the underlying drivers of this variation. We propose that the Industrial Revolution, as a key era in the history of industrialized nations, has led to a persistent clustering of well-being outcomes and personality traits associated with psychological adversity via processes of selective migration and socialization. Analyzing data from England and Wales, we examine relationships between the historical employment share in large-scale coal-based industries (coal mining and steam-powered manufacturing industries that used this coal as fuel for their steam engines) and today's regional variation in personality and well-being. Even after controlling for possible historical confounds (historical energy supply, education, wealth, geology, climate, population density), we find that the historical local dominance of large-scale coal-based industries predicts today's markers of psychological adversity (lower Conscientiousness [and order facet scores], higher Neuroticism [and anxiety and depression facet scores], lower activity [an Extraversion facet], and lower life satisfaction and life expectancy). An instrumental variable analysis, using the historical location of coalfields, supports the causal assumption behind these effects (with the exception of life satisfaction). Further analyses focusing on mechanisms hint at the roles of selective migration and persisting economic hardship. Finally, a robustness check in the U.S. replicates the effect of the historical concentration of large-scale industries on today's levels of psychological adversity. Taken together, the results show how today's regional patterns of personality and well-being (which shape the future trajectories of these regions) may have their roots in major societal changes underway decades or centuries earlier.

    Maertens, M.

    1995-01-01

    The horizontal agreements concluded between the various electric utilities within the framework of the ''Jahrhundertvertrag'', (JHV), are a violation both of section 1 GWB (act against restraints on competition) and Art. 85 of the EC Treaty, and thus are void. The same applies to the horizontal agreements concluded between the coal mining companies in Germany, representing a violation of Art. 65, section 1 of the ECSC Treaty. As a result, the various vertical contracts concluded by the electical utilities and the coal mining companies are likewise affected by the decisions declaring the above agreements to be void. None of the applicable cartel law regimes permits exemptions from prohibition of restrictive practices beyond those provided for by cartel law. The electric utilities might receive permission from the German Federal Minister of Economics under section 8, sub-sec. 2 GWB, legalizing their agreements, but this permission would give legal effect to the cartel agreements in terms of civil law only if the EC Commission would decide to exempt this cartel from prohibition of restrictive practices of the EC Treaty by a decision in compliance with Art. 85, section 3 of the EC Treaty. The horizontal agreements of the mining companies are subject to Art. 65, section 2 of the ECSC treaty, and these stringent provisions do not leave room for an exemption in this case [de

    1994-06-01

    This topical report summarizes the combustor development work accomplished under the subject contract. The objective was to develop a combustion system for the Solar 4MW Type H Centaur gas turbine generator set which was to be used to demonstrate the economic, technical and environmental feasibility of a direct coal-fueled gas turbine in a 100 hour proof-of-concept test. This program started with a design configuration derived during the CSC program. The design went through the following evolution: CSC design which had some known shortcomings, redesigned CSC now designated as the Two Stage Slagging Combustor (TSSC), improved TSSC with the PRIS evaluated in the IBSTF, and full scale design. Supporting and complimentary activities included computer modelling, flow visualization, slag removal, SO{sub x} removal, fuel injector development and fuel properties evaluation. Three combustor rigs were utilized: the TSSC, the IBSTF and the full scale rig at Peoria. The TSSC rig, which was 1/10th scale of the proposed system, consisted of a primary and secondary zone and was used to develop the primary zone performance and to evaluate SO{sub x} and slag removal and fuel properties variations. The IBSTF rig which included all the components of the proposed system was also 1/10th scale except for the particulate removal system which was about 1/30th scale. This rig was used to verify combustor performance data obtained on the TSSC and to develop the PRIS and the particulate removal system. The full scale rig initially included the primary and secondary zones and was later modified to incorporate the PRIS. The purpose of the full scale testing was to verify the scale up calculations and to provide a combustion system for the proof-of-concept engine test that was initially planned in the program.

    It is shown that innovation is regarded as a central success factor in tackling challenges of the future. Especially in high-wage regions such as Germany companies find themselves in a fierce innovation competition marked by growing challenges at the global level and the growing dynamism of innovation processes. Young industries are typically faced with much uncertainty in regard to strategy and technology, presenting their individual companies, most of them small and young themselves, with the challenge of having to rely on limited resources to develop innovative products, services and processes and launch them on the market. This provides the backdrop to the present dissertation, which inquires into the factors that determine the success of cooperative innovation projects in young branches of industry. Using the German photovoltaic industry as an example, the study empirically determines major determinants of success of joint innovation projects in young industries and derives recommendations for action for the management of companies and innovation networks.

    Coal world production represents 3.5 billions of tons, plus 900 millions of tons of lignite. 50% of coal is used for power generation, 16% by steel making industry, 5% by cement plants, and 29% for space heating and by other industries like carbo-chemistry. Coal reserves are enormous, about 1000 billions of tons (i.e. 250 years of consumption with the present day rate) but their exploitation will be in competition with less costly and less polluting energy sources. This documents treats of all aspects of coal: origin, composition, calorific value, classification, resources, reserves, production, international trade, sectoral consumption, cost, retail price, safety aspects of coal mining, environmental impacts (solid and gaseous effluents), different technologies of coal-fired power plants and their relative efficiency, alternative solutions for the recovery of coal energy (fuel cells, liquefaction).

  20. Coal information 1996

    International Nuclear Information System (INIS)

    1997-01-01

    Coal Information (1997 edition) is the latest edition of a publication that has been produced annually by the IEA since 1983. The report is intended to provide both Member countries of the OECD and those employed in all sectors of the coal industry with information on current world coal market trends and long-term prospects. It includes information on coal prices, demand, trade, supply, production capacity, transport, environmental issues (including emission standards for coal-fired boilers), coal ports, coal-fired power stations and coal used in non -OECD countries. Part I of the publication contains a wide ranging review of world coal market developments in 1996 and current prospects to 2010. The review is based on historical data of OECD energy supply and demand, data on other world regions, projections of OECD coal supply, demand and trade and information provided by the CIAB. Part II provides, in tabular and graphical form, a more detailed and comprehensive statistical picture of coal developments and future prospects for coal in the OECD, by region and for individual Member countries. Readers interested in projections are strongly advised to read the notes for individual countries in Principles and Definitions in Part II. Coal statistics for non-OECD countries are presented in Part III of the book. Summary data are available on hard coal supply and end-use statistics for about 40 countries and regions world-wide. Data are based on official national submissions to the United Nations in Geneva and New York, national energy publications, information provided to the IEA Secretariat by national statistical offices as well as other unofficial Secretariat sources. Further information on coal used in non-OECD countries is published annually by the IEA in Energy Statistics and Balances of Non-OECD Countries. Also included in Part III are the Survey of Coal Ports world-wide and the Survey of Coal-fired Power Stations in coal-importing countries

  1. Development of a software concept for computer-aided technical detail planning for machines in German hard coal mining; Entwicklung eines Softwarekonzeptes fuer rechnergestuetzte maschinentechnische Datailplanung im deutschen Steinkohlenbergbau

    1994-12-31

    CAD systems have long been an aid in German hard coal mining for reducing costs in all technical planning tasks. The use of computers will offer as yet unused possibilities for further cost savings in the future. For this purpose, this book introduces a new software concept for the technical planning for machines in the mines of the Ruhr. By the continued and thorough use of the potential of modern computer techniques, by the application of the knowledge of planning science orientated towards practice and by transferring computer-aided planning applications from other branches of industry, a further contribution is to be made to reducing costs in technical planning. The heart of the future technical planning workplace will be a graphically orientated surface with the three-dimensional representation of the pit structure on the screen. On this surface, after choosing the work area in the pit structure, there is access to the available software tools. These support the planning engineer in information and design work (connection to databank, 2D/3D-CAD, libraries of operating means and standard parts) and give support to the method of procedure (through expert systems, sample specifications, checklists). They will also offer help in inspection and decision-making (by simulation and calculation routines, expert systems) and in supporting publicity activities (text processing, desktop publishing). The computer-aided planning system of the future will develop from the two-dimensional design environment usual today into a comprehensive integrated 3D engineering system. (orig.)

  2. Price versus Non-price Incentives for Participation in Quality Labeling: The Case of the German Fruit Juice Industry

    2013-03-01

    Full Text Available Quality assurance and labeling play an important and increasing role in firms’ marketing strategies. In almost all cases, a price incentive has been stressed as the major incentive for firms to participate in such schemes. We argue here that important non-price incentives for participation in quality labeling may exist, too. In German retailing, it can be observed that discount retailers are listing more and more foods with quality labels. Processors may then participate in voluntary quality labeling in order to enter the large and growing market of discount retailers. The price-premium versus the market-entry hypothesis are analyzed theo-retically. We investigate then in an empirical hedonic pricing model for the German fruit juice market and for participation in the quality label of the Deutsche Landwirtschafts-Gesellschaft (DLG which of the two hypotheses is consistent with the data. There is strong support for the market-entry hypothesis

  4. Coal -98

    International Nuclear Information System (INIS)

    Sparre, C.

    1998-01-01

    The following report deals with the use of coal and coke during 1997. Some information about technic, environmental questions and markets are also given. Data have been collected by questionnaires to major users and by telephone to minor users. Preliminary statistical data from SCB have also been used. The use of steam coal for heating purposes during 1997 was 730 000 tons and about 500 000 tons lower than in 1996. The extremely high figures of 1996 were due to twice the production of electricity because of lack of hydro power. The co-generation plants were the main users of coal. The minor plants have increased their use of forest fuels. Probably the use of steam coal will go down in the immediate years both in the heat generating and the co-generating plants. Some foreign analysts, however, estimate a doubled use of coal for energy use after 2020 because of the plans to phase out the nuclear power. During the top year 1987 coal was used in 18 hot water plants and 11 co-generation plants. 1997 these figures are 2 and 8. Taxes and environmental reasons explain this trend. The use of steam coal in the industry has been constant at the level 700 000 tons. This level is supposed to be constant or to vary with business cycles. The import of metallurgical coal in 1997 was 1.6 mill tons like the year before. 1.2 mill tons coke were produced. The coke consumption in the industry was 1.5 Mill tons. 0.3 mill tons of coke were imported. Several other plants have plans to replace the coal with forest fuels, waste fuels and NG. Even the biggest plant, Vaesteraas, has plans to build a block for bio fuels. Helsingborg has started to use wood pellets. The pellets replace most of the coal for the heat production in the co-generation plant. Norrkoeping Kraft AB has taken a fluid bed boiler for different fuels in operation, leading to more than half the coal consumption compared with previous years. They have also rebuilt one of their travelling grates for bio fuels. Stockholm

  5. Risk management of energy efficiency projects in the industry - sample plant for injecting pulverized coal into the blast furnaces

    2016-01-01

    Full Text Available This paper analyses the applicability of well-known risk management methodologies in energy efficiency projects in the industry. The possibilities of application of the selected risk management methodology are demonstrated within the project of the plants for injecting pulverized coal into blast furnaces nos. 1 and 2, implemented by the company US STEEL SERBIA d.o.o. in Smederevo. The aim of the project was to increase energy efficiency through the reduction of the quantity of coke, whose production requires large amounts of energy, reduction of harmful exhaust emission and increase productivity of blast furnaces through the reduction of production costs. The project was complex and had high costs, so that it was necessary to predict risk events and plan responses to identified risks at an early stage of implementation, in the course of the project design, in order to minimise losses and implement the project in accordance with the defined time and cost limitations.

    This report presents a novel strategy for developing wind power on an industrial-scale in China. Oversized wind farms, large-scale electrical storage and long-distance transmission lines are integrated to deliver {open_quotes}baseload wind power{close_quotes} to distant electricity demand centers. The prospective costs for this approach to developing wind power are illustrated by modeling an oversized wind farm at Huitengxile, Inner Mongolia. Although storage adds to the total capital investment, it does not necessarily increase the cost of the delivered electricity. Storage makes it possible to increase the capacity factor of the electric transmission system, so that the unit cost for long-distance transmission is reduced. Moreover, baseload wind power is typically more valuable to the electric utility than intermittent wind power, so that storage can be economically attractive even in instances where the cost per kWh is somewhat higher than without storage. 9 refs., 3 figs., 2 tabs.

    Energy conservation technologies in the coal-fired power sector are important solutions for the environmental pollution and climate change issues. However, a unified framework for estimating their costs and potentials is still needed due to the wide technology choices, especially considering their economic feasibility under fuel and carbon price uncertainties. Therefore, this study has employed a bottom-up approach to analyze the costs and potentials of 32 key technologies’ new promotions during the 13th Five-Year Plan period (2016–2020), which combines the conservation supply curve (CSC) approach and break-even analysis. Findings show that (1) these 32 technologies have a total coal conservation potential of 275.77 Mt with a cost of 238.82 billion yuan, and their break-even coal price is 866 yuan/ton. (2) steam-water circulation system has the largest energy conservation potential in the coal-fired power industry. (3) considering the co-benefits will facilitate these technologies’ promotions, because their break-even coal prices will decrease by 2.35 yuan/ton when the carbon prices increase by 1 yuan/ton. (4) discount rates have the largest impacts on the technologies’ cost-effectiveness, while the future generation level affect their energy conservation potentials most. - Highlights: • The 32 technologies can save 275.77 Mt coal with a cost of 238.82 billion yuan. • The steam-water circulation system has the largest energy conservation potential. • Considering the co-benefits will facilitate the technology promotions • Discount rates have the largest impacts on the technologies’ cost-effectiveness.

  11. Analysis of thermal coal pricing and the coal price distortion in China from the perspective of market forces

    2017-01-01

    The price of thermal coal has always been the focus of the debate between coal mining industry and electric power industry. The thermal coal price is always lower than other same quality coal, and this phenomenon of thermal coal price distortion has been existing in China for a long time. The distortion coal price can not reflect the external cost and the resource scarcity of coal, which could result in environment deteriorating and inefficient resource allocation. This paper studied the phenomenon of thermal coal price distortion through economic theoretical modeling and empirical cointegration analysis from the perspective of market forces. The results show that thermal coal price is determined by electricity price, the prediction elasticity of a electricity enterprise, price elasticity of demand of electricity, the input prediction elasticity of a electricity enterprise and the price elasticity of supply of thermal coal. The main reason of coal price distortion is the unbalance market force of coal industry and thermal coal generation industry. The distortion rate of coal price is positively related to the market force of electric power industry and negatively related to the industrial concentration of coal industry. - Highlights: • This paper studied thermal coal pricing and the coal price distortion in China. • The main reason of coal price distortion is the unbalance market force. • Thermal coal price is also influenced by electricity price and price elasticity of demand of electricity. • The distortion rate of coal price is negatively related to the industrial concentration of coal industry.

    2013-04-01

    The year 2012 benefited from a growth of the consumption of hard coal at the national level as well as at the international level. Worldwide, the hard coal still is the number one energy source for power generation. This leads to an increasing demand for power plant coal. In this year, the conversion of hard coal into electricity also increases in this year. In contrast to this, the demand for coking coal as well as for coke of the steel industry is still declining depending on the market conditions. The enhanced utilization of coal for the domestic power generation is due to the reduction of the nuclear power from a relatively bad year for wind power as well as reduced import prices and low CO{sub 2} prices. Both justify a significant price advantage for coal in comparison to the utilisation of natural gas in power plants. This was mainly due to the price erosion of the inexpensive US coal which partly was replaced by the expansion of shale gas on the domestic market. As a result of this, the inexpensive US coal looked for an outlet for sales in Europe. The domestic hard coal has continued the process of adaptation and phase-out as scheduled. Two further hard coal mines were decommissioned in the year 2012. RAG Aktiengesellschaft (Herne, Federal Republic of Germany) running the hard coal mining in this country begins with the preparations for the activities after the time of mining.

    The purpose of State Coal Profiles is to provide basic information about the deposits, production, and use of coal in each of the 27 States with coal production in 1992. Although considerable information on coal has been published on a national level, there is a lack of a uniform overview for the individual States. This report is intended to help fill that gap and also to serve as a framework for more detailed studies. While focusing on coal output, State Coal Profiles shows that the coal-producing States are major users of coal, together accounting for about three-fourths of total US coal consumption in 1992. Each coal-producing State is profiled with a description of its coal deposits and a discussion of the development of its coal industry. Estimates of coal reserves in 1992 are categorized by mining method and sulfur content. Trends, patterns, and other information concerning production, number of mines, miners, productivity, mine price of coal, disposition, and consumption of coal are detailed in statistical tables for selected years from 1980 through 1992. In addition, coal`s contribution to the State`s estimated total energy consumption is given for 1991, the latest year for which data are available. A US summary of all data is provided for comparing individual States with the Nation as a whole. Sources of information are given at the end of the tables.

    This survey in Europe surveyed the current status of the coal industry, supporting directions and policies of governments on the coal industry, and summarized the information thereof. The survey included movements in policies and activities in transfer of technologies to overseas countries by governments and corporations of different countries, and the current status of the coal technology training project. The survey covered Britain and Germany. The British coal industry is facing a serious difficulty because the electric power industry being the major coal purchaser has changes its sourcing to natural gas. In addition, the open-cut mining which has been considered high in productivity has no further hope of big progress due to regulations in the environmental aspects. However, as a result of having performed positively research and development on production cost reduction, the production efficiency has grown excellently. Using this situation as the base, positive advancement into overseas countries is being carried out. The German coal industry has, in spite of having reduced the production size and the number of coal mines, shifted coal purchasers to electric power generation and steel making areas, and its quality and supply capability stand equivalent to those of imported coals.

    The report considers prescription for osteoarthritis of the knee in miners. Osteoarthritis of the knee, a common disorder in the general population, was last reviewed by the Council in May 1995 in its Command paper 'Disorders of the Knee' (Cm. 2842). This report follows a representation from an ex-Council member highlighting epidemiological evidence of an increased risk of this disorder in miners. The coal mining industry has undergone many changes which have decreased the extent to which miners have been exposed to such employment conditions, notably the closure of many mines by 1986. However, there is evidence that the relevant exposure circumstances will still have occurred after 1986 in certain categories of miner, such as faceworkers working nonmechanised coal faces.It is recommended that osteoarthritis of the knee should be prescribed in relation to work as an underground miner for ten years or more in aggregate; but that to be reckonable, any service from 1986 onwards should be in certain specific categories of coal mining occupation, as set out in the recommended prescription schedule. 2 apps.

  19. The need for sustainable technology diffusion in mining: Achieving the use of belt conveyor systems in the German hard-rock quarrying industry

    2017-01-01

    Full Text Available The movement of raw materials can be one of the most challenging tasks in open pit mining, with truck transportation representing the largest factor in mining costs and resulting in major greenhouse gas (GHG emissions. In this study, the transportation methods of bulk materials within German hard-rock open pit mines were investigated. Approximately 450 quarries were studied for their production tonnage, lease areas, mined rock type as well as mining methods and processing equipment. The results demonstrate that 90% of the operations use truck-based transportation methods, with the remainder relying partly or completely on continuous conveyor-based systems. The installation of continuous conveyors compared to trucks represents a real alternative because of reduced dead load, reduced GHG emissions and in many cases even reduced costs. Thus, for in-pit haulage in quarries sustainable technology substitutions exist that are yet to be adopted by the German quarrying industry. As this study shows, in the future the diffusion of sustainable technologies requires site champions and large-scale case studies that demonstrate their successful introduction in the mining value chain.

    A three phase research and development program has resulted in the development and commercialization of a Cyclone Melting System (CMS{trademark}), capable of being fueled by pulverized coal, natural gas, and other solid, gaseous, or liquid fuels, for the vitrification of industrial wastes. The Phase 3 research effort focused on the development of a process heater system to be used for producing value added glass products from the vitrification of boiler/incinerator ashes and industrial wastes. The primary objective of the Phase 3 project was to develop and integrate all the system components, from fuel through total system controls, and then test the complete system in order to evaluate its potential for successful commercialization. The demonstration test consisted of one test run with a duration of 105 hours, approximately one-half (46 hours) performed with coal as the primary fuel source (70% to 100%), the other half with natural gas. Approximately 50 hours of melting operation were performed vitrifying approximately 50,000 lbs of coal-fired utility boiler flyash/dolomite mixture, producing a fully-reacted vitrified product.

    The present book describes the development of reactor safety in German light-water nuclear power plants from the beginnings with its multifarious links to model solutions seen in other countries, national and international research projects and accidents in conventional and nuclear power plants. It contains detailed, richly illustrated articles on specific safety techniques such as rupture safety of the pressurised envelope, safeguarding of emergency cooling in the event of accidents involving coolant loss, control technology and protection of the surroundings through containment. The results of national and international risk studies are discussed. It is shown how efforts on the part of industry, government and science to enhance safety resources and improve safety culture have been driven by a civic environment in which the use of nuclear energy has become a central issue of political debate. The book is written in readily comprehensible language and offers a wealth of material for further study.

    To test the relationships among particular motives for smoking cessation, stage of readiness to quit (preparation or contemplation), and sociodemographic characteristics. A cross-sectional study to examine attitudes toward and use of health promotion at the worksite, using a self-administered questionnaire. Two German metal companies. Of 1641 responding employees (response rate 65% in company A and 44% in company B), 360 smokers who intended to quit immediately (n = 105) or in the near future (n = 255) were analyzed. The questionnaire comprised of sociodemographic characteristics, smoking behavior, smoking history, readiness to quit smoking, motives to quit, such as coworkers' complaints and health-related or financial concerns. Chi-squared tests and multiple logistic regression analyses were performed. Health-related reasons (94%) predominated financial (27%) or image-related (14%) reasons for smoking cessation. Participants in the cessation preparation group were more likely to report an awareness of being addicted (79.6% vs. 58.2%; p motives for smoking cessation, including reduced performance, family's and coworkers' complaints, pregnancy/children, and negative public image, but not health-related and financial concerns, differed significantly by gender, age, marital status, education, and occupational status. Motives for smoking cessation vary according to the individual's level of readiness to quit and sociodemographic background.

    Development of concepts and new technologies will have to pay more heed to the ecological balance of a product than in the past. The Umweltbundesamt (Federal Environmental Office) suggests to divide an ecological balance into a balance of facts, a balance of impact and include a balance sheet valuation. As there are no valid socio-political valuation criteria they suggest to use partial criteria as for instance the climate-relevant air pollution for the valuation of the refrigeration industry. This article attempts to forecast existing and foreseeable developments of the refrigeration industry under this particular aspect. (BWI) [de

    The Charbonnages de France group (French coal industry) presents several objections to the projected European Commission program concerning the reduction of air pollution emission and acidification: reaching so rapidly the projected reduction level means a drastic improvement to the large burning plants, regardless of the low operating duration of the coal plants in France, which are used for electric power production only at peak or semi-base periods or in industries (principally food industry) with low energy duration requirements, and regardless of the important emission reductions already achieved in France. The coal industry proposes to simply apply the present IPPC directive; already, turning to circulating fluidized bed units has allowed important SO{sub 2} and NO{sub x} emission reductions. The evolution of sulfur and nitrogen oxide emissions in France between 1990 and 1995 is detailed

    Full Text Available After World War I as a result of the process of "nationalization" of the existing mining companies, of the application of the Law on the commercialization of the economic enterprises of the State of 7 June 1925, of the general trend of creating new industrial companies, in the Jiu Valley will continue operation many mining companies, called upon to exploit the rich coal deposit existing in the basement of the region. To the recovery period and then to momentum of the world economy during the third decade of the twentieth century, follows, however in a specific economic cyclicity, the period of economic crisis of the years 1929-1933. By crisis is also struck still from years 1926-1927, mining and quarrying of coal, and consequently the coal mining from the Jiu Valley, and one of the levers by which those who have led the destinies of this economic complex tried to pull the region out of crisis was the policy of rationalization, through which was aimed, primarily, a decrease in material costs through a better organization of work and through a renewal of the fixed capital based on the new technique that allowed an increase in labor productivity. Not in the least, it is accented in this period the concentration process of production and capital, either through mergers or by seizing small mining companies or undertakings, whether by purchase of land in order to form large mining complexes.

    A survey was made in India which is a coal producing/consuming country following China in Asia and where coal is used for about 60% of the primary commercial energy. The survey was conducted on coal production/distribution/utilization and environmental issues, aiming at studying feasibility of introducing the environmentally friendly coal utilization system into every industry including the residential/commercial one, and at implementing a comprehensive master plan including Japan`s international cooperation. Total power source facilities in fiscal 1995 are 83.3 million kW, 64% of which are coal thermal power facilities and generated 260 TWh, 69% of the total output energy. Main commercial energy sources are coal, oil and natural gas, and oil is self-sufficient. The survey this time did not examine very well the actual state of the environmental pollution problem caused by the coal utilization. Indian coal is high in ash content but low in sulfur content, and therefore, SOx polluting air has not been a very important problem so far, but soot/smoke is almost the problem. Further, ash treatment after combustion at boilers, etc. is expected to be a big problem in the future. 49 figs., 88 tabs.

    Since 1998, The Pennsylvania State University has been successfully managing the Consortium for Premium Carbon Products from Coal (CPCPC), which is a vehicle for industry-driven research on the promotion, development, and transfer of innovative technology on premium carbon produces from coal to the U.S. industry. The CPCPC is an initiative being led by Penn State, its co-charter member West Virginia University (WVU), and the U.S. Department of Energy's (DOE) National Energy Technology Laboratory (NETL), who also provides the base funding for the program, with Penn State responsible for consortium management. CPCPC began in 1998 under DOE Cooperative Agreement No. DE-FC26-98FT40350. This agreement ended November 2004 but the CPCPC activity has continued under the present cooperative agreement, No. DE-FC26-03NT41874, which started October 1, 2003. The objective of the second agreement is to continue the successful operation of the CPCPC. The CPCPC has enjoyed tremendous success with its organizational structure, that includes Penn State and WVU as charter members, numerous industrial affiliate members, and strategic university affiliate members together with NETL, forming a vibrant and creative team for innovative research in the area of transforming coal to carbon products. The key aspect of CPCPC is its industry-led council that selects proposals submitted by CPCPC members to ensure CPCPC target areas have strong industrial support. Base funding for the selected projects is provided by NETL with matching funds from industry. At the annual funding meeting held in October 2003, ten projects were selected for funding. Subcontracts were let from Penn State to the subcontractors on March 1, 2004. Nine of the ten 2004 projects were completed during the previous annual reporting period and their final reports were submitted with the previous annual report (i.e., 10/01/04-09/30/05).

    1982-01-01

    Under the with-project scenario, WyCoalGas is projected to make a difference in the long-range future of Converse County. Because of the size of the proposed construction and operations work forces, the projected changes in employment, income, labor force, and population will alter Converse County's economic role in the region. Specifically, as growth occurs, Converse County will begin to satisfy a larger portion of its own higher-ordered demands, those that are currently being satisfied by the economy of Casper. Business-serving and household-serving activities, currently absent, will find the larger income and population base forecast to occur with the WyCoalGas project desirable. Converse County's economy will begin to mature, moving away from strict dependence on extractive industries to a more sophisticated structure that could eventually appeal to national, and certainly, regional markets. The technical demand of the WyCoalGas plant will mean a significant influx of varying occupations and skills. The creation of basic manufacturing, advanced trade and service sectors, and concomitant finance and transportation firms will make Converse County more economically autonomous. The county will also begin to serve market center functions for the smaller counties of eastern Wyoming that currently rely on Casper, Cheyenne or other distant market centers. The projected conditions expected to exist in the absence of the WyCoalGas project, the socioeconomic conditions that would accompany the project, and the differences between the two scenarios are considered. The analysis is keyed to the linkages between Converse County and Natrona County.

    Lignite has a key role to play in the transformation of the energy system due to its specific structural features in terms of industry, company history, policy, economics, the environment and regional structures. Understanding these structural features of the German lignite industry is an important requirement for classifying the significance of the lignite industry up to now and for the redesigning of this industrial sector. From these environmental, economic and regulatory structural characteristics, which are interwoven in a variety of ways, the incentives arise for the mining and power plant operators to react to energy price signals or energy policy steering. The aim of this research study is to define these structural features, to compile comprehensively the basic data and information that is not always transparently available, to understand the interactions, to enable the navigation of issues that are partly very complex, and to classify into the long-term developments that are especially important for political and social processes. In 2016 approx. 12 percent of German primary energy consumption was met using lignite. At the same time, lignite has the highest carbon dioxide (CO2) emissions of the fossil fuels; it currently accounts for approx. 19 percent of Germany's total greenhouse gas emissions as well as approx. 46 percent of the total CO2 emissions of the electricity sector. As a result of the mining of lignite and its conversion into electricity, substantial adverse impacts beyond the entry of greenhouse gases into the Earth's atmosphere arise for other environmental media. These impacts include half of Germany's mercury emissions, approx. a third of its sulfur dioxide emissions and approx. a tenth of its nitrogen oxide emissions. Lignite mining in open-cast mines takes up a substantial amount of landscape and soil and requires huge interventions in the water balance. Relatively high costs arise for the recultivation and rehabilitation

  7. Coal: Less than lackluster

    International Nuclear Information System (INIS)

    Doerell, P.

    1994-01-01

    Not many in the world coal industry will remember 1993 as a good year. The reasons for the poor state of affairs were first the weak economic climate, and second, the energy glut. For the first time after expanding steadily since the 70s, seaborne trade in hard coal fell by about 4% to 350M mt. Steam coal accounted for a good half of this volume. While demand continued to rise in the newly industrialized countries of the Pacific area, imports into Europe of both coking coal and steam coal fell sharply. The United States, CIS, and Canada had to accept substantial losses of export volume. Australia, as well as South Africa, Colombia, and Indonesia consolidated their market positions and Poland, too, recorded high volumes available for export. The positive news came from Australia, where in mid-December the New South Wales coal industry reported an increase in the net profit after tax from $A83M (about $55M) to $A98M (about $126M) in 1992/1993. This success was however ascribed less to an improvement in the fundamental mining indicators than to the fall in the Australian dollar and the lowering of corporate tax. The reduction in capital investment by 26% down to $A330M (after the previous year when it had also been cut by 25%) is seen by the chairman of the NSW Coal Assoc. as not auguring well for the industry's ability to meet the forecast growth in demand to the year 2000

  9. The role of multiple regression and exploratory data analysis in the development of leukemia incidence risk models for comparison of radionuclide air stack emissions from nuclear and coal power industries

    International Nuclear Information System (INIS)

    Prybutok, V.R.

    1995-01-01

    Risk associated with power generation must be identified to make intelligent choices between alternate power technologies. Radionuclide air stack emissions for a single coal plant and a single nuclear plant are used to compute the single plant leukemia incidence risk and total industry leukemia incidence risk. Leukemia incidence is the response variable as a function of radionuclide bone dose for the six proposed dose response curves considered. During normal operation a coal plant has higher radionuclide emissions than a nuclear plant and the coal industry has a higher leukaemia incidence risk than the nuclear industry, unless a nuclear accident occurs. Variation of nuclear accident size allows quantification of the impact of accidents on the total industry leukemia incidence risk comparison. The leukemia incidence risk is quantified as the number of accidents of a given size for the nuclear industry leukemia incidence risk to equal the coal industry leukemia incidence risk. The general linear model is used to develop equations that relate the accident frequency required for equal industry risks to the magnitude of the nuclear emission. Exploratory data analysis revealed that the relationship between the natural log of accident number versus the natural log of accident size is linear. (Author)

    Sparre, C.

    1994-05-01

    This report deals with use of coal and coke during 1993; information about techniques, environmental questions and markets are also given. Use of steamcoal for heating purposes has been reduced about 3 % during 1993 to 1,0 mill tons. This is the case especially for the heat generating boilers. Production in co-generation plants has been constant and has increased for electricity production. Minor plants have increased their use of forest fuels, LPG and NG. Use of steamcoal will probably go down in the immediate years both in heat generating and co-generating plants. Coal-based electricity has been imported from Denmark during 1993 corresponding to about 400 000 tons of coal, when several of our nuclear plants were stopped. Use of steamcoal in the industry has been constant at 700 000 tons. This level is supposed to be constant or to vary with business cycles. The import of metallurgical coal in 1993 was 1,6 mill tons like the year before. 1,2 mill tons coke were produced. Coke consumption in industry was 1,4 mill tons. 0,2 mill tons of coke were imported. Average price of steamcoal imported to Sweden in 1993 was 308 SEK/ton or 13 % higher than in 1992; this can be explained by the dollar price level increasing 34% in 1993. For the world, the average import price was 50,0 USD/ton, a decrease of 6 %. The coal market during 1993 was affected by less consumption in Europe, shut downs of European mines and decreasing prices. High freight price raises in Russia has affected the Russian export and the market in northern Europe. The prices have been stabilized recently. All Swedish plants meet emission limits of dust, SO 2 and NO x . Co-generation plants all have some sort of SO 2 -removal system; the wet-dry method is mostly used. A positive effect of the recently introduced NO x -duties is a 40% reduction

    , pressures, and volumetric flows practically identical. In POGT mode, the turbine specific power (turbine net power per lb mass flow from expander exhaust) is twice the value of the onventional turbine. POGT based IGCC plant conceptual design was developed and major components have been identified. Fuel flexible fluid bed gasifier, and novel POGT unit are the key components of the 100 MW IGCC plant for co producing electricity, hydrogen and/or yngas. Plant performances were calculated for bituminous coal and oxygen blown versions. Various POGT based, natural gas fueled systems for production of electricity only, coproduction of electricity and hydrogen, and co production of electricity and syngas for gas to liquid and hemical processes were developed and evaluated. Performance calculations for several versions of these systems were conducted. 64.6 % LHV efficiency for fuel to electricity in combined cycle was achieved. Such a high efficiency arise from using of syngas from POGT exhaust s a fuel that can provide required temperature level for superheated steam generation in HRSG, as well as combustion air preheating. Studies of POGT materials and combustion instabilities in POR were conducted and results reported. Preliminary market assessment was performed, and recommendations for POGT systems applications in oil industry were defined. POGT technology is ready to proceed to the engineering prototype stage, which is recommended.

  12. The Charfuel coal refining process

    Meyer, L.G.

    1991-01-01

    The patented Charfuel coal refining process employs fluidized hydrocracking to produce char and liquid products from virtually all types of volatile-containing coals, including low rank coal and lignite. It is not gasification or liquefaction which require the addition of expensive oxygen or hydrogen or the use of extreme heat or pressure. It is not the German pyrolysis process that merely 'cooks' the coal, producing coke and tar-like liquids. Rather, the Charfuel coal refining process involves thermal hydrocracking which results in the rearrangement of hydrogen within the coal molecule to produce a slate of co-products. In the Charfuel process, pulverized coal is rapidly heated in a reducing atmosphere in the presence of internally generated process hydrogen. This hydrogen rearrangement allows refinement of various ranks of coals to produce a pipeline transportable, slurry-type, environmentally clean boiler fuel and a slate of value-added traditional fuel and chemical feedstock co-products. Using coal and oxygen as the only feedstocks, the Charfuel hydrocracking technology economically removes much of the fuel nitrogen, sulfur, and potential air toxics (such as chlorine, mercury, beryllium, etc.) from the coal, resulting in a high heating value, clean burning fuel which can increase power plant efficiency while reducing operating costs. The paper describes the process, its thermal efficiency, its use in power plants, its pipeline transport, co-products, environmental and energy benefits, and economics

  13. The world behind electricity from coal. The dubious origin of coal for Dutch coal-fired power plants

    International Nuclear Information System (INIS)

    2008-01-01

    Five energy companies in the Netherlands want to build additional coal-fired power plants: Essent and Nuon, the German company RWE and E.ON and the Belgian company Electrabel. Coal-fired power plants emit 70 percent more CO2 than gas-fired power plants. Especially because of the threat to the climate Greenpeace believes that no more coal-fired power plants should be built. In this publication Greenpeace explores the pollution, the working conditions and human rights with regard to the exploitation of coal. That has been elaborated for the three countries from which Dutch energy companies import coal: South Africa, Colombia and Indonesia. In addition to information about the origin of coal also insight is given into the coal market (stocks and use), the enormous coal transport and the world trade [nl

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

    1997-12-31

    The role of state and class formation in Nova Scotia before Confederation is discussed. The farming and coal mining districts of northern Nova Scotia are described as opposing segments that together were central to the development of liberal capitalist government forms in the province. A range of economic circumstances is considered: squatters, estates, mixed farming, coal mining, trading, quarrying, and fraternal societies. The role of enterprises such as the General Mining Association, a British venture, in colonization and in constraint of local initiative and accumulation is considered. Rural liberals created a positive place in self-government, while colonial liberals constructed a liberalism that was centred around the state and economic progress. The poor and those without property were allotted marginal public roles.

    It is thought that environmental prevention technologies related to boilers which are the largest coal use field in China have been almost all made model projects till now. Further, coal or coke is used in various industrial furnaces except boilers in every industrial sector in China. The amount of coal use there is large next to that in boilers, which is a cause of the country`s serious air pollution. Accordingly, an investigation was commenced in fiscal 1997 aiming at grasping the actual state of environmental pollution caused by various coal related industrial furnaces in China and studying the environmental improvement. This time, various industrial furnaces were examined in chemical and iron/steel industries. It could be inferred that both industries made efforts to enhance and rationalize production activities and then give consideration also to the environmental prevention. Generally, however, most plants still have old-fashioned production facilities, while the facilities are being modernized little by little. It was found that in China productivity was lower than Japan and the environmental pollution was in a serious condition. 16 refs., 28 figs., 69 tabs.

  19. Competition through regulation - efforts aimed at reform in the European and German gas industries: Appropriate, feasible and consistent with the economic facts?

    International Nuclear Information System (INIS)

    Klaue, S.

    1994-01-01

    At the forefront of the ongoing debate in Europe on the political, economic and legal aspects of energy supplies are considerations for introducing a new regulatory framework, especially the general third-party access (TPA) regime for grid energies. Most advocates of such reform claim that it is needed for the sake of more competition in the energy sector. However, they do not set out from economic facts and seek a solution to the problems. Instead, the solution is laid down as the target, to which the economic facts are subordinated. Blind activism inspired by theoretical motives and without regard for the consequences must be avoided. Otherwise there is a danger of the new framework being unsuitable for really bringing about any movement, be it in the intended direction or towards the envisaged goal. The introduction of general TPA can only be successful if there are certain structures and market trends. Do such structures and market trends exist in the European and German gas industries? In answering this question, it is necessary to proceed from the economic conditions, on which both a general and an economical/legal assessment of reform efforts should actually be based. Reference is therefore made to Jonathan P. Stern, who gathered in facts and whose evaluations are taken into account here. (orig.)

    The present book provides an overview of the energy market of the German Federal Republic. Its main emphasis is on structures of demand and supply in the markets for crude oil, brown coal, hard coal, natural gas and electricity. A special chapter has been dedicated to renewable energy resources. Another focal area are the price formation mechanisms for oil, coal, natural gas and electricity. The development of energy demand is analysed, differentiating between the sectors industry, transport, households and trade/industry/services. The book addresses the international climate protection treaties, the legal framework for climate protection activities at the European level and the implementation of trade in greenhouse gas emission permits in Germany. It presents current forecasts and scenarios, thus pointing out possible perspectives in the German energy market. It also discusses the framework conditions for Germany's energy policy. The energy markets are portrayed through facts and figures compiled in a total of 125 tables and 148 diagrams. Details of ownership of more than 100 utility companies are made transparent. The chapter on energy in the coalition agreement of 27 November 2013 between the Christian Democratic Union, Christian Social Union and the Social Democratic Party is documented verbatim. Rounding off the publication is a detailed glossary that will facilitate the reader's understanding of complex matters in the field of energy economy.

    The focus is on the Central Appalachian coal industry. Alpha Natural Resources was formed in 2002 from Pittston Coal's Virginia and Coastal operations. AMCI's U.S. operations and Mears Enterprises in Pennsylvania were acquired later. The company produces 20-21 million tonnes per year and sells 20 million tonnes of steam coal and 10 million tonnes of exports, including some coal that is brokered. Foundry coke is a major product. Capital investment has resulted in increased productivity. Central Appalachia is expected to continue as a significant coal-producing region for supplying metallurgical coke. Production is expected to stabilize, but not increase; so the mines will have a longer life. 31 slides/overheads are included.

    This paper discusses figures and achievements of the brown coal and energy industry in the German Democratic Republic for the year 1980 along with projected figures for the planned period 1981 to 1985 and up to 1990. Brown coal production in 1980 amounted to 258 Mt and will be increased to 290 Mt in 1985. In order to achieve this goal 9 new brown coal surface mines will be opened, the technological basis of the mines will be computer controlled belt conveyor transportation, which has shown the highest work productivity. Efficiency and capacity of overburden removal equipment will be further increased, the utilization of mine drainage water will increase from 19% in 1980 to 32% in 1985. The carbochemical industry, producing at present a crude oil equivalent of 7 Mt, will raise production to 8 Mt in 1985 and 11 Mt in 1990. A prime focus of R and D has been the successfully concluded technology of producing high quality brown coal briquets and coke for the carbide industry and metallurgy, with which black coal coke can be substituted. Brown coal gasification in Winkler generators for production of synthesis gas will be doubled in the next years. The electric energy supply is planned to be increased by 3,000 to 3,600 MW, predominantly with brown coal fired 500 MW and 210 MW blocks. A method for substituting heating oil by brown coal dust during start-up and manoeuvering of 350t/h steam generators has also been successfully developed. Heating oil combustion will further be substituted by newly developed small brown coal dust fired 0.8 t/h and 6.5 t/h steam generators. Rational energy utilization, substitution of imported energy, increasing application of microelectronics and industrial roots in the coal industry are further broad goals for the near future.

    In recent years, studies have been initiated to explore the possibilities of the use of biological systems in coal technology. This chapter discusses the principles behind the bioprocessing of coal, the advantages and disadvantages, and the economic feasibility of the process. For large-scale, coal-using, energy-producing plants, stack gas cleaning should be the treatment of choice. Biodesulfurization is preferable with industrial, small-scale, energy-producing plants. Treatment of the stack gases of these plants is not advisable because of high investment costs. Finally, it should be realized that biodesulfurization produces a waste stream that needs further treatment. 91 refs

Its future will be shaped by its ability to meet expected international increases in demand for thermal coal, and by profitability and possible impact of greenhouse strategy decisions. By 2002 the demand for the State's coal is estimated at a total of 116 million tons and it expected to play an increased role in the fuel mix for electricity generation because of its competitive price, established technologies and abundant supply

  13. Re-Industrialisation and Low-Carbon Economy—Can They Go Together? Results from Stakeholder-Based Scenarios for Energy-Intensive Industries in the German State of North Rhine Westphalia

    Full Text Available The German federal state of North Rhine-Westphalia (NRW is home to one of the most important industrial regions in Europe, and is the first German state to have adopted its own Climate Protection Law (CPL. This paper describes the long-term (up to 2050 mitigation scenarios for NRW’s main energy-intensive industrial sub-sectors which served to support the implementation of the CPL. It also describes the process of scenario development, as these scenarios were developed through stakeholder participation. The scenarios considered three different pathways (best-available technologies, break-through technologies, and CO2 capture and storage. All pathways had optimistic assumptions on the rate of industrial growth and availability of low-carbon electricity. We find that a policy of “re-industrialisation” for NRW based on the current industrial structures (assumed here to represent an average growth of NRWs industrial gross value added (GVA of 1.6% per year until 2030 and 0.6% per year from 2030 to 2050, would pose a significant challenge for the achievement of overall energy demand and German greenhouse gas (GHG emission targets, in particular as remaining efficiency potentials in NRW are limited. In the best-available technology (BAT scenario CO2 emission reductions of only 16% are achieved, whereas the low carbon (LC and the carbon capture and storage (CCS scenario achieve 50% and 79% reduction respectively. Our results indicate the importance of successful development and implementation of a decarbonised electricity supply and breakthrough technologies in industry—such as electrification, hydrogen-based processes for steel, alternative cements or CCS—if significant growth is to be achieved in combination with climate mitigation. They, however, also show that technological solutions alone, together with unmitigated growth in consumption of material goods, could be insufficient to meet GHG reduction targets in industry.

  14. Review of a Proposed Quarterly Coal Publication

    1981-01-01

    This Review of a Proposed Quartery Coal Publication contains findings and recommendations regarding the content of a new summary Energy Information Administration (EIA) coal and coke publication entitled The Quarterly Coal Review (QCR). It is divided into five sections: results of interviews with selected EIA data users; identification of major functions of the coal and coke industries; analysis of coal and coke data collection activities; evaluation of issues conerning data presentation including recommendations for the content of the proposed QCR; and comparison of the proposed QCR with other EIA publications. Major findings and recommendations are as follows: (1) User interviews indicate a definite need for a compehensive publication that would support analyses and examine economic, supply and demand trends in the coal industry; (2) the organization of the publication should reflect the natural order of activities of the coal and coke industries. Based on an analysis of the industries, these functions are: production, stocks, imports, exports, distribution, and consumption; (3) current EIA coal and coke surveys collect sufficient data to provide a summary of the coal and coke industries on a quarterly basis; (4) coal and coke data should be presented separately. Coke data could be presented as an appendix; (5) three geographic aggregations are recommended in the QCR. These are: US total, coal producing districts, and state; (6) coal consumption data should be consolidated into four major consumer categories: electric utilities, coke plants, other industrial, and residential commercial; (7) several EIA publications could be eliminated by the proposed QCR.

    The environmental technology is one of the most important growth markets worldwide. In the light of the unique environmental political challenges predictions refer to an expansionary trend towards market development - especially in the international context, with particular emphasis on the climate protection. The companies of the German environmental industry increasingly operate in global markets. A major share of that growth has been developed there. Temporarily, only the foreign market offered expansion opportunities. Even if the companies are not active on the export markets, the companies in the domestic market compete with their international export markets. Insofar, the question of the international competitiveness of the environmental industry is a key issue.

  18. Mid-point review of the German energy transition

    Lauer, H.; Safa, H.; Guidez, J.

    2017-01-01

    The result of the 2015 review of the German energy transition is lukewarm. First: generating 20 % of the electricity production through wind power and solar energy appears to be very costly in Germany. Secondly there is practically no effect on the reduction of CO_2 releases as coal has been re-introduced to play the role of nuclear energy which was carbon-free to counter-balance the intermittency of renewable energies. Thirdly a necessity to keep all thermal plants ready to operate in order to cope with the intermittency of renewable energies as no adequate means of energy storage is available, appears to be a luxury that only Germany can afford. And fourthly, the cost of electric power for households and small enterprises is all the higher as the government economic policy is to spare German electro-intensive industry. One of the side effects of the German energy transition policy is to disturb the European market of electricity when favourable climate conditions make green electricity very abundant. In this situation electricity prices drop sharply and can even become negative while green electricity is always paid to the producer at a steady price guaranteed by the state. (A.C.)

    Three sediment cores were collected from a wharf near a coal-based steel refining industrial zone in Kaohsiung, Taiwan. Analyses for 16 polycyclic aromatic hydrocarbons (PAHs) of the US Environmental Protection Agency priority list in the core sediment samples were conducted using gas chromatography-mass spectrometry. The vertical profiles of PAHs in the core sediments were assessed, possible sources and apportionment were identified, and the toxicity risk of the core sediments was determined. The results from the sediment analyses showed that total concentrations of the 16 PAHs varied from 11774 ± 4244 to 16755 ± 4593 ng/g dry weight (dw). Generally, the vertical profiles of the PAHs in the sediment cores exhibited a decreasing trend from the top to the lower levels of the S1 core and an increasing trend of PAHs from the top to the lower levels of the S2 and S3 cores. Among the core sediment samples, the five- and six-ring PAHs were predominantly in the S1 core, ranging from 42 to 54 %, whereas the composition of the PAHs in the S2 and S3 cores were distributed equally across three groups: two- and three-ring, four-ring, and five- and six-ring PAHs. The results indicated that PAH contamination at the site of the S1 core had a different source. The molecular indices and principal component analyses with multivariate linear regression were used to determine the source contributions, with the results showing that the contributions of coal, oil-related, and vehicle sources were 38.6, 35.9, and 25.5 %, respectively. A PAH toxicity assessment using the mean effect range-median quotient (m-ERM-q, 0.59-0.79), benzo[a]pyrene toxicity equivalent (TEQ(carc), 1466-1954 ng TEQ/g dw), and dioxin toxicity equivalent (TEQ(fish), 3036-4174 pg TEQ/g dw) identified the wharf as the most affected area. The results can be used for regular monitoring, and future pollution prevention and management should target the coal-based industries in this region for pollution reduction.
