  1. Privatisation: saving the British coal industry?

    Energy Technology Data Exchange (ETDEWEB)

    Robinson, C.

    1995-11-01

    Britain`s coal industry was privatised at the end of 1994, after about forty eight years of state ownership. This paper beings with a very brief sketch of the history of coal mining in Britain, including the events which led up to privatisation. It then explains the privatisation scheme and assesses its implications. 21 refs., 3 figs., 1 tab.

  2. British Coal Corporation Medical Service annual report 1988-89

    Energy Technology Data Exchange (ETDEWEB)

    1992-01-01

    This annual report reviews the work of British Coal's Medical Service over the period 1988-89. Recruitment was at a lower level resulting in a reduction in the number of pre-employment medical examinations. Statistics are given for these, and for consultations during the year. The work of the rescue service is described. Results of surveys on the prevalence of pneumoconiosis in coal miners from 1961 to 1988 are presented in detail. The fall in prevalence continued. Continued attention has been paid to compliance with COSHH regulations, to encouraging the use of physiotherapy and to educating workers in lifting and handling methods. Following an incidence of Legionnaires Disease an investigation was carried out to identify the source of infection in an underground refrigeration plant. Studies on the mortality of coke workers have progressed. Reports are given on first aid and nursing services and on the administration of pethridine to injured miners.

    Harvie, D.

    1996-02-01

    An economic model, using OLS regression, of aggregate productivity in the post-war British coal industry is presented. Some of the methods used by Weisskopf, Bowles and Gordon (1983) in their `social model` of aggregate productivity in the US economy are drawn upon; however, all `social` variables included in this coal productivity model are found not to be significant. The results suggest that pit closures have been an important source of aggregate productivity growth throughout the period; this does not imply, however, that `unproductive`, or `uneconomic`, pits are intrinsically so, rather their status as such may be the result of a political process. Average colliery size and the industry`s capital stock were also found to be important explanatory variables. Attention was paid to the effects of the national miners` strikes during the period; these were found to be structurally insignificant. 45 refs., 10 figs., 5 tabs.

  4. British Coal Medical Service annual report 1989-90

    Energy Technology Data Exchange (ETDEWEB)

    1990-01-01

    The report contains detailed results of surveys on the prevalence of pneumoconiosis in coal miners of various age groups from 1962 to 1989. Only 0.6% of 14,300 men X-rayed in 1989 showed any sign of the disease and the overall figure for the 112 collieries surveyed after the completed seventh round of surveys was 0.7%. Emphasis has continued on dust control measures on coal faces and in drivages - dust concentration of 3.1 mg/m {sup 3} in 1989-90 was in keeping with the trend since 1970. A 'cohort' of young miners is being monitored to develop an early warning system to identify changes in the incidence of pneumoconiosis. The role of Medical Service in treating injuries, skin diseases, back pain etc. and problems caused by noise and chemicals is explained. Continued attention has been paid to implication of the COSHH regulations and audiometry has been introduced to all British Coal's employees. Services are now provided to workers of Coal Products Ltd. Reports of first aid and nursing services are included. Use of pethidine for relieving pain is now being advocated. 6 figs., 20 tabs.

    The Pneumoconiosis Field Research (PFR) programme was established in the 1950s, to evaluate effects of coal mining exposures on the health and mortality of British coal workers. Surveys of working miners were carried out at 5-yearly intervals, initially in 24 collieries but later concentrating on 10, collecting detailed work histories and health information for each recruit. Here we report on cause-specific mortality in a cohort of almost 18,000 men from 10 British collieries, followed up for periods up to 47 years, yielding over 516,000 life-years of follow-up. External analyses compared cause-specific death rates in the cohort to those of the population of the regions in which the collieries were situated, using Standardised Mortality Ratios (SMRs). The causes investigated included lung cancer, stomach cancer, non-malignant respiratory disorders and cardiovascular disorders. SMRs showed evidence of an initial healthy worker effect diminishing over time. Several causes, including non-malignant respiratory disease and lung cancer, showed a significant deficit of mortality at the start of the study period with an excess in the latter part of the follow-up period. In these results, effects of working conditions are likely to be confounded with smoking habits. Overall, we believe our results may be generalised to the British coal industry since nationalisation.

    2010-04-15

    In the 1950s the Pneumoconiosis Field Research (PFR) programme was set up to study the health of British coal workers. Studies included regular health surveys, an intensive characterisation of workers' individual exposures, and entry to a cohort followed up to the present for cause-specific mortality. This study reports on analyses of cause-specific mortality in a cohort of almost 18 000 men from 10 British collieries. External analyses used standardised mortality ratios (SMRs), comparing observed mortality with reference rates from the regions in which the collieries were situated. Causes investigated include lung and stomach cancers, chronic obstructive pulmonary disease and cardiovascular endpoints. Internal analyses used Cox regression models with time-dependent exposures adjusting for the confounding effects of age, smoking, cohort entry date and regional differences in population mortality rates. Several causes showed evidence of a healthy worker effect early in the follow-up, with a deficit in the SMR diminishing over time. For most of the causes there was a significant excess in the latter part of follow-up. Internal analyses found evidence of an association between increased risks of lung cancer and increased quartz exposure, particularly at a lag of 15 years. Risks of mortality from non-malignant respiratory disease showed increases with increased exposure to respirable dust. This paper adds to the evidence on the long-term effects of exposure to coalmine dust on mortality from respiratory diseases.

    Transport of coal by train through residential neighborhoods in Metro Vancouver, British Columbia, Canada may increase the possibility of exposure to particulate matter at different size ranges, with concomitant potential negative health impacts. This pilot study identifies and quantifies train impacts on particulate matter (PM) concentrations at a single location. Field work was conducted during August and September 2014, with the attributes of a subset of passing trains confirmed visually, and the majority of passages identified with audio data. In addition to fixed ground based monitors at distances 15 and 50 m from the train tracks, an horizontally pointing mini-micropulse lidar system was deployed on three days to make backscatter and depolarization measurements in an attempt to identify the zone of influence, and sources, of train-generated PM. Ancillary wind and dust fall data were also utilized. Trains carrying coal are associated with a 5.3 (54%), 4.1 (33%), and 2.6 (17%) μgm(-3) average increase in concentration over a 14 min period compared to the average concentrations over the 10 min prior to and after a train passage ("control" or "background" conditions), for PM3, PM10, and PM20, respectively. In addition, for PM10 and PM20, concentrations during train passages of non-coal-carrying trains were not found to be significantly different from PM concentrations during control conditions. Presence of coal dust particles at the site was confirmed by dust fall measurements. Although enhancements of PM concentrations during 14 min train passages were generally modest, passing coal trains occasionally enhanced concentrations at 50 m from the tracks by ∼100 μgm(-3). Results showed that not every train passage increased PM concentrations, and the effect appears to be highly dependent on wind direction, local meteorology and load related factors. LiDAR imagery suggests that re-mobilization of track-side PM by train-induced turbulence may be a significant

  11. A very British phenomenon? Industrial politics and the decline of the Japanese coal mining industry since the 1950s

    This paper describes how the Japanese government gradually abandoned its support for coal mining after 1945. Drawing parallels with the British experience during the 1930s, this article shows how coal miners and owners in Japan were able to slow the pace of economic adjustment from the 1950s. The government's initial reluctance to act reflected its willingness to put industrial politics to the fore, preferring to avoid alienating political support and aggravating a vocal unionised sector of the labour force. It eventually accepted and acted upon the need for draconian retrenchment.

    Selenium (Se) concentrations in surface water downstream of surface mining operations have been reported at levels in excess of water quality guidelines for the protection of wildlife. Previous research in surface mining environments has focused on downstream water quality impacts, yet little is known about the fundamental controls on Se loading. This study investigated the relationship between mining practices, stream flows and Se concentrations using a SPAtially Referenced Regression On Watershed attributes (SPARROW) model. This work is part of a R&D program examining the influence of surface coal mining on hydrological and water quality responses in the Elk Valley, British Columbia, Canada, aimed at informing effective management responses. Results indicate that waste rock volume, a product of mining activity, accounted for roughly 80% of the Se load from the Elk Valley, while background sources accounted for roughly 13%. Wet years were characterized by more than twice the Se load of dry years. A number of variables regarding placement of waste rock within the catchments, length of buried streams, and the construction of rock drains did not significantly influence the Se load. The age of the waste rock, the proportion of waste rock surface reclaimed, and the ratio of waste rock pile side area to top area all varied inversely with the Se load from watersheds containing waste rock. These results suggest operational practices that are likely to reduce the release of Se to surface waters.

    Surface mining is a common method of accessing coal. In high-elevation environments, vegetation and soils are typically removed prior to the blasting of overburden rock, thereby allowing access to mineable ore. Following this, the removed overburden rock is deposited in adjacent valleys as waste rock spoils. Previous research has identified that areas downstream of surface coal mining have impaired water quality, yet there is limited information about the interaction of hydrology and geochemistry across a range of mining conditions, particularly at the headwater scale. Here, we provide an analysis of an extensive long-term data set of geochemistry and flows across a gradient of coal mining in the Elk Valley, British Columbia, Canada. This work is part of a broader R&D program examining the influence of surface coal mining on hydrological and water quality responses in the Elk Valley aimed at informing effective management responses. Results indicate that water from waste rock piles has an ionic profile distinct from unimpacted catchments. While the concentration of geochemicals increased with the degree of mine impact, the control of hydrological transport capacity over geochemical export did not vary with degree of mine impact. Geochemical export in mine-influenced catchments was limited more strongly by transport capacity than supply, implying that more water moving through the waste rock mobilized more geochemicals. Placement of waste rock within the catchment (headwaters or outlet) did not affect chemical concentrations but did alter the timing with which chemically distinct water mixed. This work advances on results reported earlier using empirical models of selenium loading and further highlights the importance of limiting water inputs into waste rock piles.

    Two new species of euthycarcinoids (Arthropoda), Kottixerxes anglicus sp. nov. and Smithixerxes pustulosus sp. nov., are described from the Coal Measures of Westhoughton, Lancashire and Coseley, West Midlands (Westphalian A and B respectively). Both genera are previously known from Mazon Creek, USA (Westphalian D). An additional, enigmatic arthropod with possible euthycarcinoid affinities, Arthrogyrinus platyurus gen. et sp. nov., is described from Coseley. Hypotheses concerning the phylogenetic position of euthycarcinoids are critically reviewed.

    Exposure of coal waste rock to atmospheric oxygen can result in the oxidation of sulfide minerals and the release of sulfate (SO4(2-)) and associated trace elements (e.g., Se, As, Cd, and Zn) to groundwaters and surface waters. Similarly, reduced iron minerals such as siderite, ankerite, and the sulfide, pyrite, present in the waste rock can also undergo oxidation, resulting in the formation of iron oxyhydroxides that can adsorb trace elements released from the oxidation of the sulfide minerals. Characterization and quantification of the distribution of sulfide and iron minerals, their oxidation products, as well as leaching rates are critical to assessing present-day and future impacts of SO4(2-) and associated trace elements on receiving waters. Synchrotron-based X-ray absorption near edge spectroscopic analysis of coal waste rock samples from the Elk Valley, British Columbia showed Fe present as pyrite (mean 6.0%), siderite (mean 44.3%), goethite (mean 35.4%), and lepidocrocite (mean 14.3%) with S present as sulfide (mean 26.9%), organic S (mean 58.7%), and SO4(2-) (mean 14.4%). Squeezed porewater samples from dump solids yielded mean concentrations of 0.28mg/L Fe and 1246mg/L SO4(2-). Geochemical modeling showed the porewaters in the dumps to be supersaturated with respect to Fe oxyhydroxides and undersaturated with respect to gypsum, consistent with solids analyses. Coupling Fe and S mineralogical data with long-term water quality and quantity measurements from the base of one dump suggest about 10% of the sulfides (which represent 2% of total S) in the dump were oxidized over the past 30years. The S from these oxidized sulfides was released to the receiving surface water as SO4(2-) and the majority of the Fe precipitated as secondary Fe oxyhydroxides (only 3.0×10(-5)% of the Fe was released to the receiving waters over the past 30years). Although the data suggest that the leaching of SO4(2-) from the waste rock dump could continue for about 300years

    This study investigated the geochemistry of arsenic (As) in low sulfide-high carbonate coal waste rock of the Elk Valley, British Columbia, Canada. Its abundance and mineralogical associations in waste rock of different placement periods were determined in addition to its mobilization into porewater and rock-drain effluent. The mean (5.34mg/kg; 95% confidence interval: 4.95-5.73mg/kg) As concentration in the waste rock was typical of sedimentary rock. Electron microprobe and As K-edge X-ray absorption near-edge spectroscopic analyses showed the As is predominantly associated with primary pyrites in both source and freshly blasted waste rock. However, in aged waste rock the As is associated with both primary pyrites and secondary Fe oxyhydroxides. Oxidation of pyrite in waste rock dumps was reflected by the presence of high concentrations of SO4(2-) in porewater and oxidation rims of Fe oxyhydroxides around pyrite grains. Acid released from pyrite oxidation to Fe oxyhydroxides is neutralized by carbonate mineral dissolution that buffers the pH in the waste rock to circumneutral values. Adsorption of As onto secondary Fe oxyhydroxides provides an internal geochemical control on As release during pyrite oxidation and porewater flushing from the dump, resulting in the low As concentrations observed in porewater (median: 9.91μg/L) and rock-drain effluent (median: 0.31μg/L). Secondary Fe oxyhydroxides act as a long-term sink for As under present day hydrologic settings in waste rock dumps in the Elk Valley.

    This annual conference fostered the exchange of information on mine reclamation and related issues affecting coal mining in British Columbia and oil sand mining in Alberta. The Technical and Research Committee on Reclamation (TRCR) was launched in the early 1970 to address the need for greater communication between industry and government regarding environmental protection and mine reclamation in order to minimize the environmental damages and impacts to wildlife posed by resource development. The Acid Mine Drainage Task Force was recently amalgamated with the TRCR to ensure that acid rock drainage issues are fully addressed. The conference was attended by members of the mining industry, consultants, students, all levels of government, non government organizations, and other interested parties from within British Columbia and around the world. The environmental impacts of mine development and land rehabilitation were discussed along with new remedial methods for soil conservation, water protection and carbon sequestration. The conference featured 22 presentations, of which 12 have been catalogued separately for inclusion in this database. refs., tabs., figs.

    The applicability of the reflectance micro-Fourier Transform infra-red spectroscopy (FTIR) technique for analyzing the distribution of functional groups in coal macerals is discussed. High quality of spectra, comparable to those obtained using other FTIR techniques (KBr pellet and transmission micro-FTIR), indicate this technique can be applied to characterizing functional groups under most conditions. The ease of sample preparation, the potential to analyze large intact samples, and ability to characterize organic matter in areas as small as 20 ??m are the main advantages of reflectance micro-FTIR. The quantitative aspects of reflectance micro-FTIR require further study. The examples from the coal seams of the Mist Mountain Formation, British Columbia show that at high volatile bituminous rank, reflectance micro-FTIR provides valuable information on the character of aliphatic chains of vitrinite and liptinite macerals. Because the character of aliphatic chains influences bond disassociation energies, such information is useful from a hydrocarbon generation viewpoint. In medium volatile bituminous coal liptinite macerals are usually not detectable but this technique can be used to study the degree of oxidation and reactivity of vitrinite and semifusinite.

    The novel system of EBA (based on external circulation anaerobic (EC) process-biological enhanced (BE) process-anoxic/oxic (A/O) process) was applied to treat the British Gas/Lurgi coal gasification wastewater in Erdos, China. After a long time of commissioning, the EBA system represented a stable and highly efficient performance, particularly, the concentrations of COD, NH4(+)-N, total organic carbon, total nitrogen and volatile phenols in the final effluent reached 53, 0.3, 18, 106mg/L and not detected, respectively. Both the GC-MS and fluorescence excitation-emission matrix analyses revealed significant variations of organic compositions in the effluent of different process. The results of high-throughput sequencing represented the EBA system composed 34 main bacteria which were affiliated to 7 phyla. In addition, the canonical correspondence analysis indicated high coherence among community composition, wastewater characteristics and environmental variables, in which the pH, mixed liquid suspended solids and total phenols loading were the most three significant variables.

    The present study is a compilation of published data on coal facies studies in Canada based on coal petrological and other methods. The geological age of the coals range from the Devonian coal deposits in Arctic Canada to coals of Tertiary age in the Western Canada Sedimentary Basin, intermontane British Columbia and Arctic Canada. In terms of rank, the coal deposits studied range from lignite to low volatile bituminous. Coal petrological methods include maceral and microlithotype analyses, frequently integrated with data from palynological and geochemical analyses. Most recently, a number of studies have applied sequence stratigraphic concepts to the coal-bearing strata including the interpretation of coal petrological data in the context of this concept.

    Energy Technology Data Exchange (ETDEWEB)

    Walker, S. [Independent Editorial and Technical Services, Oxford (United Kingdom)

    1998-04-01

    A recent British court case awarded retired coal miners compensation for asthma, chronic bronchitis and emphysema. Although the sums involved were small, large numbers of retired coal miners are likely to be eligible for such awards, as British safety in mines was not substantially worse than most other producers at the time, and was better than many. In some parts of the world safety standards are still poor. Dust suppression should be used on coal cutting machines, and dust controlled in transit. This may prove less expensive than it initially appears since the coal dust can be used instead of lost. This particularly important for transport in open trucks. Employers must also ensure that the safety equipment supplied is both comfortable and used. 3 refs., 5 photos.

  9. Thatcherism and the fall of coal

    Energy Technology Data Exchange (ETDEWEB)

    Parker, M.J.

    2000-07-01

    When Margaret Thatcher was elected Prime Minister in 1979, British coal mines employed over 200,000 people and produced over 100 million tonnes of coal a year. By the end of the 1990s, more than 95% of these jobs and 80% of coal production no longer existed. The author, a member of the British Government's Energy Advisory Panel, describes the industry's decline, attributing it to a combination of the Thatcherite political agenda, economic forces and the industry's own actions.

  10. An evaluation of microwave-driven stannylation followed by in situ {sup 119}Sn MAS n.m.r. spectroscopy as a probe for hydroxyl functionality in medium-rank British coals and macerals

    The paper describes the derivatization of hydroxyl groups in coals and coal macerals by stannylation. Stannylation of a range of phenolic compounds with Me{sub 3}SnCl, Bu{sub 3}SnCl and (Bu{sub 3}Sn){sub 2}O (TMTO) was carried out under both microwave-driven and conventional conditions. The degree of Stannylation was influenced by the steric environment of the OH group, implying that stannylation in comparison with, say trimethylsilylation of OH groups could help to map the steric environments of phenolic groups in coals. Good maceral separations of Creswell coal and acceptable separation of Cottonwood coal were achieved. The whole coals and the macerals were stannylated with TBTO under microwave-enhanced conditions and the products were examined by {sup 119}Sn MAS n.m.r. and X-ray photoelectron spectroscopy. The reaction was confined to surface regions. Differences were found in the behaviour of the macerals. The crystal and molecular structures of the trimethylstannyl derivative of 2,6-diphenylphenol were determined, to establish the validity of the claim to have stannylated model compounds. Molecular parameters were compared with related systems. 18 refs., 3 figs., 5 tabs.

  16. Coal in Canada : production staying strong in the west

    Energy Technology Data Exchange (ETDEWEB)

    Zlotnikov, D.

    2007-09-15

    Most coal operations in Canada are in Saskatchewan, Alberta and British Columbia, with some ongoing coal production in Nova Scotia and New Brunswick. This article discussed the factors that influence the growth distribution of coal. While metallurgical coal produced in British Columbia is primarily exported, Canada's thermal coal production is largely consumed internally, nearly exclusively for power generation purposes. Thermal coal in the provinces of Nova Scotia, New Brunswick, Saskatchewan and Alberta has increased steadily. Although Ontario is a big coal consumer, it has seen a reduced consumption in recent years due to a higher output from its nuclear fleet. Coal is evaluated by a set of properties, including its thermal content and the nature of impurities in the coal such as ash, moisture and sulphur. Quality and heating value are important because each power plant is designed for certain coal characteristics. Most of Canada's thermal coal production is directed to mine-mouth operations, notably power plants that were built in the immediate vicinity of a mine in order to keep transportation costs as low as possible. The single largest driver for the revival of seaborne thermal and metallurgical coal markets is the pronounced growth in China and the associated demand for raw materials to fuel the growth. This article listed the major coal producers in Canada along with their production capacity. 3 figs.

  1. The strongest links : the Canadian coal chain

    Energy Technology Data Exchange (ETDEWEB)

    Moore, E.

    2008-09-15

    Issues related to the transportation of coal in Canada were discussed. Coal mines in Alberta and British Columbia are often required to transport their products over 1000 km for export at Pacific ports to countries in Asia or power plants in Ontario. The effectiveness of the supply chain is dependent on the inter-relationships between mine, rail, terminals, and ship transport. Coal customers are typically required to hire shipping companies and nominate vessels for terminals that have contracts with coal suppliers. Mines typically inform railway lines of the amounts of coal that will need to be transported each month. Many railways have increased the amounts of coal they are transporting by using lighter-weight aluminum train cars. Further efficiencies have been realized due to new braking and power distribution technologies in trains. Multiple locomotives are now also being used to provide improved control over the cars that carry the coal. Despite advances in rail technologies, coal deliveries are often delayed by harsh weather conditions and rain. It was concluded that the Canadian coal industry's success relies on its ability to transport large amounts of coal across long distances. 2 figs.

Over the course of cohort members lives, the BCS70 has collected information on health, physical, educational and social development, and economic circumstances among other factors. Since the birth survey in 1970, there have been nine ‘sweeps’ of all cohort members at ages 5, 10, 16, 26, 30, 34, 38 and most recently at 42. Data has been collected from a number of different sources (the midwife present at birth, parents of the cohort members, head and class teachers, school health service personnel and the cohort members themselves. The data has been collected in a variety of ways including via paper and electronic questionnaires, clinical records, medical examinations, physical measurements, tests of ability, educational assessments and diaries. The majority of BCS70 survey data can be accessed by bona fide researchers through the UK Data Service at the University of Essex.

    2016-12-01

    Full Text Available There have been a significant number of published studies in recent years on the British media representation of Muslims. These studies have tended to focus only on the British mainstream media, and to my knowledge, there is no significant research on the discursive construction of British Muslims in alternative media outlets. This paper attempts to fill this gap, focusing on the representations of British Muslims in the British Christian print media. Drawing on empirical data relating to four British Christian print media, Church Times, The Tablet, Evangelicals Now and Evangelical Times, this paper investigates how the questions of being Muslim and being British are dealt with in the British Christian print media, and the extent to which the politics of being Muslim and being British inform us about identity formation and affirmation.

    The proximate analysis has been useful in finding out the percentage of ash in coal, which is the threshold requirement by which the commercial value of coal is adjudged. In the present study, a rapid method for determination of ash percentage in coal has been discussed. Rapid method is always warranted to release more quality parameters within scheduled time. The results obtained by this method were found to be satisfactory and comparable with the results obtained by the British Standard specifications. It is concluded that this method can be effectively adopted where sulphur, carbonates and alkalis are present in low amounts. 4 refs., 3 tabs.

    The article, based on a Science Policy and Research Unit report entitled 'Unequal treatment: British policies for coal and nuclear power 1979-92', examines the objectives and results of UK government policies for coal and nuclear power since Margaret Thatcher entered office. During this period there was a sharp transition from high to low energy prices in the mid-1980s, with a decline of traditional concerns over the security of energy supply. Towards the end of the period environmental concerns gained importance, and the electricity industry was privatised, with, according to the authors, adverse consequences for both coal and nuclear power. Throughout, there was no formal framework of energy policy. 4 refs., 1 fig., 2 photos.

    2008-01-01

    Three coal samples of different ranks were used to study the effect of coal blending on the preparation of Coal Water Slurry (CWS). The results show that by taking advantage of two kinds of coal, the coal concentration in slurry made from hard-to-pulp coal can be effectively improved and increased by 3%-5% generally. DLT coal (DaLiuTa coal mine) is very poor in slurryability and the stability and rheology of the resulting slurry are not very good. When the amount of easily slurried coal is more than 30%, all properties of the CWS improve and the CWS meets the requirements for use as fuel. Coalification, porosity, surface oxygenic functional groups, zeta potential and grindability have a great effect on the performance of blended coal CWS. This leads to some differences in performance between the slurry made from a single coal and slurry made from blended coal.

    In the nineteenth century coal-miners imported from Europe, Asia, and eastern North America burrowed beneath the Vancouver Island towns of Nanaimo, Wellington, and Cumberland. The book looks at British Columbia's first working class, the men, women, and children beneath and beyond the pit-head. Beginning with an exploration of emigrant expectations and ambitions, it investigates working conditions, household wages, racism, industrial organization, gender, schooling, leisure, community building, and the fluid identity of the British mining colony, the archetypal west coast proletariat. By connecting the story of Vancouver Island to the larger story of Victorian industrialization, the author delineates what was distinctive and what was common about the lot of the settler society.

    Discussion is presented of the use of the Leco Mac-400 Proximate Analyser at the Ravenscraig Steel Works, UK. It is used for the analysis of in-plant coals and the determination of ash in coke. The instrument does not meet the British Standard requirement for repeatability, so is not used for 'value in use' coal analysis. It has recently been overhauled, however, and will be re-evaluated to see if the overhaul has brought an improvement in performance. 6 figs., 7 tabs.

  19. Supply constraints : Australia and Canada coal industry face logistics and capacity challenges

    Borsato, J.

    2010-09-15

    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.

  20. Dust concentrations and respiratory risks in coalminers: key risk estimates from the British Pneumoconiosis Field Research

    Soutar, C.A.; Hurley, J.F.; Miller, B.G.; Cowie, H.A.; Buchanan, D. [Inst. of Occupational Medicine, Edinburgh (United Kingdom)

    2004-06-01

    To help inform the setting of dust control standards in coal mines, this brief review summarises the most recent and reliable exposure-response relations, for damaging respiratory effects, derived from the Pneumoconiosis Field Research (PFR). Collecting data over 38 years in the British coal industry, this was a programme of prospective research on the respiratory health of coal miners, characterised by regular health surveys and detailed measurements of dust and silica concentrations in the workplace. Exposure-response relations are presented for coal workers' simple pneumoconiosis category II, progressive massive fibrosis, defined deficits of lung function (FEV1), and category II silicosis. This simplified overview provides a guide to the most recent and most reliable estimates from the PFR of dust-related risks of substantial pulmonary disease, and to the magnitude of the effects. Control of dust sufficient to prevent category II simple pneumoconiosis should prevent most cases of progressive massive fibrosis and most dust related large lung function deficits. Where the dust contains high proportions of silica, control to low levels is essential, and even quite brief excursions of silica to high levels must be avoided.

  1. Convergence, divergence and realignment in British macroeconomics

    Directory of Open Access Journals (Sweden)

    D. COBHAM

    2013-12-01

    Full Text Available In this paper the author argues that the still frequent and simplistic distinction between Keynesians and monetarists that makes up a large part of the British popular economic debate has become seriously misleading. Changes that have taken place in British macroeconomics since the early 1970s are thus indicated and some of the theoretical and empirical factors responsible for these changes are suggested. The author presents a brief characterisation of British Keynesianism and monetarism as of late 1960s/early 1970s, arguing that there have been important elements of convergence. He proceeds to discuss some of the theoretical developments and some of the experiences of UK macroeconomic policy which have contributed to this convergence. Finally, he considers whether the labels “Keynesian” and “monetarist” continue to be relevant.

    Full Text Available Four overlapping analytical frameworks focusing upon domestic British politics are applied to explain the detailed development of the policy on the euro maintained by the Conservative Government then Party in opposition and the Labour Party opposition and then Government: intra-party politics; inter-party politics; public opinion and the nature of British democracy; and neo-pluralism (competing economic and other interests. This article posits that British government - and in particular Labour Government - reluctance to hold a referendum on euro membership and actively push a pro-euro policy can be best explained in terms of ideologically infused intra- (rather than inter- party politics and the realities of pluralist politics, while explanations rooted in an analysis of public opinion are less helpful.

    Full Text Available This essay explores the ways in which the exhibition Real/Life: New British Art was conceived and received in Japan, where contemporary British art has been shown since the 1960s. Taking place at five museums in the country between 1998 and 1999, the exhibition aimed to showhow British artists in the 1990s struggled with realities, internal and external, but its response was not as satisfactory as was expected. The essay examines the exhibition as a turning point for the transformation of exhibition culture in Japan from nationally themed exhibitions to showcases of contemporary art in the global context.

  6. Revision of the Xenacanthida (Chondrichthyes : Elasmobranchii) from the Carboniferous of the British Isles

    Energy Technology Data Exchange (ETDEWEB)

    Hampe, O. [Humboldt University, Berlin (Germany)

    2003-07-01

    Xenacanthids were a very successful group of elasmobranchs that ranged from the Lower Carboniferous to the Upper Triassic. The history of discovery of the xenacanthids, which is closely connected with the history of coal prospecting in England, began with the finding of the type specimen of Xenacanthus laevissimus in the Westphalian B of the West Midlands. In this first review of British Carboniferous xenacanthids, the number of taxa, mainly erected during Victorian times, is reduced to 14 species distributed among six genera. Determinable remains are recorded from at least 96 localities in the British Isles. Unique characteristics of the Dinantian Diplodoselache suggest that the lineage to which this taxon belongs marks a dead end in xenacanthid evolution. This investigation also shows that the Pendleian Dicentrodus, formerly described as Cladodus, belongs to the xenacanthids. The occurrence of Orthacanthus cf. kounoviensis in the Pennines, also known from the German Saar-Nahe basin, the Saale depression and from Bohemia, indicates a faunal exchange between these intramontainous basins during the Carboniferous. The genus Triodus is identified from British deposits for the first time. A cladistic analysis of the xenacanthids suggests that they evolved from phoebodontid elasmobranchs. This analysis also confirms separation of the Middle Devonian Antarctilamna from a relationship with xenacanthid sharks.

    Kenny, D. A.

    2010-12-01

    The 1952 “Killer Smog” left over 4000 citizens of Greater London dead in a single week. It was a highly visible environmental disaster, which pinned the British government with responsibility over factory and domestic coal smoke pollution. Within four years of the Smog, the British parliament passed the 1956 Clean Air Act, which was designed primarily to prevent the release of dark smoke from the chimneys of private dwellings and factories. This act is considered a significant turning point in the history of environmental regulation. Through the analysis of confidential documents from government ministries and Members of Parliament, my research has focused on how decisions were made following this man-made environmental catastrophe. The primary focus of this presentation will be to explore why the British government appeared lethargic in the face of its long-standing coal pollution problem and why it finally passed the first clean air act in the world. In this case, establishing responsibility and organizing research were the major time constraints on policy action. In the months following the 1952 Smog, government departments passed off responsibility and quarreled over jurisdiction in the smog matter. Ministries held responsible for air pollution jointly established the Committee on Air Pollution to find a solution to urban smog. In the years following, the Committee on Air Pollution compiled research on the health effects and economic impact of air pollution, deriving its information from a variety of sources. In its 1954 final report, the committee named smoke and sulfur dioxide the most likely culprits of the 1952 deaths, and it recommended the elimination of smoke-producing coal from the British market, a major change to how the British fueled their homes and factories. The resulting 1956 Clean Air Act was the product of numerous compromises over the economic, political, and social issues present in Great Britain at the time. The British government

    The paper discusses the demonstration of the British Steel/CPC-Macawber Blast Furnace Granular Coal Injection (BFGCI) technology that was installed on the blast furnaces at Bethlehem Steel's Burns Harbor Plant in Indiana as a highly successful Clean Coal Technology project, cofunded by the U.S. Department of Energy. In the BFGCI process, granular coal (10%-30% through a 200-mesh screen) is injected into a blast furnace as a fuel supplement to decrease coke requirements, thus reducing costs. Tests run to determine the effect of process variables on furnace operations showed that granular coal works as well as pulverized coal and is easier to handle and cheaper to produce because of reduced grinding costs.

  12. Coal char fragmentation during pulverized coal combustion

    Energy Technology Data Exchange (ETDEWEB)

    Baxter, L.L.

    1995-07-01

    A series of investigations of coal and char fragmentation during pulverized coal combustion is reported for a suite of coals ranging in rank from lignite to low-volatile (lv) bituminous coal under combustion conditions similar to those found in commercial-scale boilers. Experimental measurements are described that utilize identical particle sizing characteristics to determine initial and final size distributions. Mechanistic interpretation of the data suggest that coal fragmentation is an insignificant event and that char fragmentation is controlled by char structure. Chars forming cenospheres fragment more extensively than solid chars. Among the chars that fragment, large particles produce more fine material than small particles. In all cases, coal and char fragmentation are seen to be sufficiently minor as to be relatively insignificant factors influencing fly ash size distribution, particle loading, and char burnout.

    The Upgraded Coal Interest Group (UCIG) is an EPRI 'users group' that focuses on clean, low-cost options for coal-based power generation. The UCIG covers topics that involve (1) pre-combustion processes, (2) co-firing systems and fuels, and (3) reburn using coal-derived or biomass-derived fuels. The UCIG mission is to preserve and expand the economic use of coal for energy. By reducing the fuel costs and environmental impacts of coal-fired power generation, existing units become more cost effective and thus new units utilizing advanced combustion technologies are more likely to be coal-fired.

    Coal fires have a very long history in China; the oldest coal fires have being burning for many million years. Up to now more than 56 coal fires spots were distinguished. They mainly locate in West-North of China, North of China and East-North of China. About millions of tons of coal have been burned in fires every year. Xinjiang Autonomy is the most serious region in coal fires as it has 38 coal fires spots and about 6.85 million tons of coal was burned every year. Coal fires in China ignited by wildfires, spontaneous combustion and human being during mining activities. These fires have released about 0.9 million tons of gasses (including CO, CO2, SO2, NO2 CH4, CO2, H2S etc.) into the atmosphere every year, most of which are brought to the east by wind and resulting more heavier air pollution in northern China.

  19. Continuous coal processing method

    Ryason, P. R.

    1980-06-01

    A coal pump is provided in which solid coal is heated in the barrel of an extruder under pressure to a temperature at which the coal assumes plastic properties. The coal is continuously extruded, without static zones, using, for example, screw extrusion preferably without venting through a reduced diameter die to form a dispersed spray. As a result, the dispersed coal may be continuously injected into vessels or combustors at any pressure up to the maximum pressure developed in the extrusion device. The coal may be premixed with other materials such as desulfurization aids or reducible metal ores so that reactions occur, during or after conversion to its plastic state. Alternatively, the coal may be processed and caused to react after extrusion, through the die, with, for example, liquid oxidizers, whereby a coal reactor is provided.

    Three hundred and six coal samples were taken from main coal mines of twenty-six provinces, autonomous regions, and municipalities in China, according to the resource distribution and coal-forming periods as well as the coal ranks and coal yields. Nitrogen was determined by using the Kjeldahl method at U. S. Geological Survey (USGS), which exhibit a normal frequency distribution. The nitrogen contents of over 90% Chinese coal vary from 0.52% to 1.41% and the average nitrogen content is recommended to be 0.98%. Nitrogen in coal exists primarily in organic form. There is a slight positive relationship between nitrogen content and coal ranking. ?? 2011 Science Press, Institute of Geochemistry, CAS and Springer Berlin Heidelberg.

  2. Thermoluminescence dating of the british coversand deposits

    Science.gov (United States)

    Bateman, M. D.

    Coversand deposits, thought to be of Lateglacial age are found in Britain in North Lincolnshire, South-West Lancashire and Central East Anglia. A comprehensive dating study of them, using thermoluminescence (TL) techniques, is currently underway in an attempt to link the British coversand deposits to the European coversand chronology. Initial results from four of the British coversand sites sampled are presented. The 26 TL dates from 14 samples show that in Lincolnshire aeolian deposition took place from 12.5 ka to I1 ka. Cessation of the initial sand deposition was synchronous with this in Lancashire, but sand deposition occurred significantly earlier in East Anglia. The upper layers of aeolian sand in Lancashire are much younger and are attributed to Holocene reworking. On the basis of these dates, Lincolnshire and Lancashire coversand deposition occurred at a similar time to the Younger Coversand II, whilst East Anglian coversand deposition coincided with the Younger Coversand I phase in the European coversand chronology.

    2007-06-01

    Although globalization has highlighted the danger of conflating state, society and nation, sociologists remain insufficiently alert to such banal nationalism. Newspapers offer a strong test case of the extent of diversity in the construction of state, national and social boundaries, since Billig and Anderson have argued they comprise a special case where their orientation to an audience simultaneously located in a state, society and nation allows them to reproduce a sense of national identity. However, despite the commonsense obviousness of the term, it proves remarkably difficult to define what the 'British national press' might comprise. Circulation density of titles varies substantially across different parts of the UK and editorial copy is altered to address diverse 'national' readerships. 'British' newspapers also circulate in other states, especially the Republic of Ireland. After reviewing how newspapers might be defined as 'national' and/or 'British', we conclude that both Anderson and Billig over-estimate the congruence, relevance and obviousness of state, society and national boundaries. If the conceptualization of such boundaries is problematic in the case of the press, it follows that it must be still more so for most other objects of sociological analysis, including that of 'society' itself.

    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).

    This report describes the technical progress made on the Advanced Coal Conversion Process (ACCP) Demonstration Project from January 1, 1995 through December 31, 1995. This project demonstrates an advanced, thermal, coal upgrading process, coupled with physical cleaning techniques, that is designed to upgrade high-moisture, low-rank coals to a high-quality, low-sulfur fuel, registered as the SynCoal Process. The coal is processed through three stages (two heating stages followed by an inert cooling stage) of vibrating fluidized bed reactors that remove chemically bound water, carboxyl groups, and volatile sulfur compounds. After thermal upgrading, the coal is put through a deep-bed stratifier cleaning process to separate the pyrite-rich ash from the coal. The SynCoal Process enhances low-rank, western coals, usually with a moisture content of 25 to 55 percent, sulfur content of 0.5 to 1.5 percent, and heating value of 5,5000 to 9,000 British thermal units per pound (Btu/lb), by producing a stable, upgraded, coal product with a moisture content as low as 1 percent, sulfur content as low as 0.3 percent, and heating value up to 12,000 Btu/lb. During this reporting period, the primary focus for the ACCP Demonstration Project team was to expand SynCoal market awareness and acceptability for both the products and the technology. The ACCP Project team continued to focus on improving the operation, developing commercial markets, and improving the SynCoal products as well as the product`s acceptance.

    Biagioni, K. [Victoria Univ., BC (Canada)

    2005-07-01

    Abandoned coal mine groundwater frequently contains depressed pH levels and elevated levels of hydrogen sulphide, iron, aluminium and nitrates. Abandoned coal mine groundwater is also usually high in copper, zinc, mercury, and lead. Groundwater from abandoned mines can seriously affect public health through the discharge of non-point source pollution. This paper presents information on a research project regarding the possible impacts of abandoned coal mines and its effects on groundwater as it relates to the health of residents in South Wellington, Nanaimo, British Columbia. The purpose of the project is to determine which illnesses are more common in South Wellington, Nanaimo and in the control area. The paper provides a discussion of the Nanaimo coal field and three major seams; the Wellington, Newcastle and Douglas which are most likely to have a significant impact on groundwater in South Wellington. 27 refs.

    It is highly important to investigate relationship between coal characteristics and methane adsorption on coal in the fields of coalbed methane recovery. Based on data examination of coal quality indexes collected from the literatures, regression equations for Langmuir adsorption constants, VL or VL/PL, and coal quality indexes for selected coal samples were developed with multiple linear regression of SPSS software according to the degree of coal metamorphosis. The regression equations built were tested with data collected from some literatures, and the influences of coal quality indexes on CH4 adsorption on coals were studied with investigation of regression equations, and the reasons of low accuracy to Langmuir constants calculated with regression equation for a few coal samples were investigated. The results show that the regression equations can be employed to predict Langmuir constants for methane adsorption isotherms on coals obtained using volumetric gas adsorption experiments, which are conducted at 30 ℃ on a wet or dried coal samples with less than 30% ash content in coal. The influence of same coal quality index with various coal rank or influence of various coal quality indexes for same coal rank on CH4 adsorption is not consistent. The regression equations have different accuracy to different coal rank, in which the VL equations supply better prediction accuracy for anthracite and higher prediction error for lower metamorphosis coal, and the PL prediction error with VL and VL/PL equations is lower to bituminous coal and higher to anthracite.

    Coal tar is one of the oldest treatments for psoriasis and eczema. It has anti-inflammatory, antibacterial, antipruritic and antimitotic effects. The short-term side effects are folliculitis, irritation and contact allergy. Coal tar contains carcinogens. The carcinogenicity of coal tar has been shown in animal studies and studies in occupational settings. There is no clear evidence of an increased risk of skin tumors or internal tumors. Until now, most studies have been fairly small and they did not investigate the risk of coal tar alone, but the risk of coal tar combined with other therapies. New, well-designed, epidemiological studies are necessary to assess the risk of skin tumors and other malignancies after dermatological use of coal tar.

    Full Text Available This work evaluated the char morphology of beneficiated and original coal (without beneficiation from four Colombian coalmines: Cerrejón (La Guajira, La Jagua (Cesar, Guachinte (Valle del Cauca and Nechí (Antioquia. Column flotation was used to obtain beneficiated coal, whereas a drop tube reactor at 1,000°C, 104 °C/s heating rate and 100 ms residence time was used to obtain char. The chars were analysed by image analysis which determined their shape, size, porosity and wall thickness. It was found that char morphology depended on coal rank and maceral composition. Morphological characteristics like high porosity, thinner walls and network-like morphology which are beneficial in improving combustion were present in vitrinite- and liptinite-rich lowest-ranking coals. Beneficiated coals showed that their chars had better performance regarding their morphological characteristics than their original coal chars.

    Full Text Available The subjects of Owen Hatherley’s A Guide to the New Ruins of Great Britain are architecture and urban development. The book addresses also some broader cultural, political and economic references, as well as personal anecdotes and memories. It includes many encounters with the remnants of the British welfare state.As an extension to his blog postings and a sequel of sorts to his previous Militant Modernism, Hatherley’s antagonist here is the semi-official architecture of New Labour, which he terms ‘pseudomodernism’: an unimaginative, inferior, and, in its own specific way, also tacky architecture of white stucco, steel and glass. He attacks the Faustian bargain of Richard Rogers and his allies with neoliberalism, a pact that produces a modernism devoid of social content, reflected by the unimaginative, speculation-driven architectural design. While Hatherley produces the promised indictment of recent British architecture, the book is, at the end of the day, primarily a eulogy to the disappearing postwar architecture he so evidently loves.

Some considerations will be made upon the chart so as to understand it, such as an analysis of irony and native speakers’ perspectives on it. In addition to that, we will take into account the opinion of some native speakers of English to unveil some details and clarify how meaningful some sentences may be and if the researched chart is actually accurate

    Full Text Available The paper presents a review of relevant literature on coal pyrolysis.Pyrolysis, as a process technology, has received considerable attention from many researchers because it is an important intermediate stage in coal conversion.Reactions parameters as the temperature, pressure, coal particle size, heating rate, soak time, type of reactor, etc. determine the total carbon conversion and the transport of volatiles and therebythe product distribution. Part of the possible environmental pollutants could be removed by optimising the pyrolysis conditions. Therefore, this process will be subsequently interesting for coal utilization in the future

    2003-11-01

    This study explores the dynamics of racism, specifically its generation and reproduction as an ideology, and its role in affecting the reception and occupational location of migrant medical labour in Britain. It is argued that the treatment of 'overseas doctors' in Britain draws on a complex interplay between racism and nationalism underpinned by the historical construction of 'welfarism' as a moral legitimator of 'Britishness'. Through an exploration of internal and external immigration controls introduced with the aim of regulating migrant labour, we demonstrate how British social policy and elite discourses of 'race' combine to construct moral prescriptions of threat such that migrants and British-born 'non-whites' entering the British medical profession are forced to negotiate 'saviour/pariah' ascriptions indicative of discriminatory but contradictory processes specific to the operation of the British National Health Service as a normative institution.

    British cognitive developmental psychology is characterized by its interest in philosophical questions, its preference for linking basic research to applied issues in education and cognitive disorders, and its willingness to learn both methodologically and theoretically from work in animal psychology and in physiology more generally. It has also been influenced profoundly by Jean Piaget's cognitive stage theory although in general British work has focused on demonstrating early strengths, rather than early deficits, in infant and child cognition. Following an overview of British work that encompasses past and present interests, issues and challenges for the future are highlighted. While the perspectives of the founding members of the British Psychological Society (BPS), as outlined by Edgell (1947), are still apparent in British research in cognitive developmental psychology today, it is argued that future cognitive work must become even more interdisciplinary and that the symbiotic relationship between research in adult cognition and in cognitive development needs greater recognition.

    Energy Technology Data Exchange (ETDEWEB)

    1994-02-02

    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.

It not only includes the history and cultural background of a nation, but also fosters the nation ’s attitudes towards life, and ways of living and thinking of the nation. Therefore, to my point of view, the cause of language differences is basically the differences between cultures.

  6. Population Ecology of Caribou in British Columbia

    1996-01-01

    Full Text Available The abundance and geographic range of woodland caribou (Rangifer tarandus caribou decreased in many areas of British Columbia during the 1900's. Recent studies have found that predation during the summer is the major cause of mortality and current population declines. Increased moose {Alecs alces populations may be related to past and current caribou declines by sustaining greater numbers of wolves (Canis lupus. Mortality rates were greater in areas where caribou calved in forested habitats, in close proximity to predators and moose. Caribou populations which had calving sites in alpine areas, islands, and rugged mountains experienced lower mortality and were generally stable or increasing. A predator-induced population decline in one area appeared to stabilize at low caribou densities, suggesting that the wolf predation rate may be density dependent.

    Metaphyseal osteopathy, otherwise known as hypertrophic osteodystrophy, is a disease that causes pyrexia and lethargy accompanied by pain in the thoracic and pelvic limbs of rapidly growing large-breed dogs. While metaphyseal osteopathy has been descibed in association with slipped capital femoral epiphysis in cats, it has not previously been reported as a cause of limb pain and pyrexia in this species. A 7-month-old British Shorthair cat presented with a 1 month history of pyrexia, lethargy and pain in all limbs. Investigation included radiographs of the limbs and chest, abdominal ultrasound, serum biochemical analysis, haematology, bone biopsy, joint fluid aspiration and cytology. Findings were consistent with a diagnosis of metaphyseal osteopathy. The cat's clinical signs resolved following the administration of prednisolone. Symptoms recurred 1 month after the cessation of prednisolone therapy, but resolved when administration was resumed.

    It is an important issue to expand stable coal supply areas for Japan, especially to assure stable supply of overseas coals. The investigations on geological structures in foreign countries perform surveys on geological structures in overseas coal producing countries and basic feasibility studies. The investigations select areas with greater business risks in coal producing countries and among private business entities. The geological structure investigations were carried out on China, Indonesia and Malaysia and the basic feasibility studies on Indonesia during fiscal 1994. The basic coal resource development investigations refer to the results of previous physical explorations and drilling tests to develop practical exploration technologies for coal resources in foreign countries. The development feasibility studies on overseas coals conduct technological consultation, surface surveys, physical explorations, and trial drilling operations, and provide fund assistance to activities related thereto. Fiscal 1994 has provided fund assistance to two projects in Indonesia and America. Fund loans are provided on investigations for development and import of overseas coals and other related activities.

    Bishop, B.; Goldsmith, R. [CeraMem Corp., Waltham, MA (United States)

    1995-12-31

    Removal of mineral matter from liquid hydrocarbons derived from the direct liquefaction of coal is required for product acceptability. Current methods include critical solvent deashing (Rose{sup {reg_sign}} process from Kerr-McGee) and filtration (U.S. Filter leaf filter as used by British Coal). These methods produce ash reject streams containing up to 15% of the liquid hydrocarbon product. Consequently, CeraMem proposed the use of low cost, ceramic crossflow membranes for the filtration of coal liquids bottoms to remove mineral matter and subsequent diafiltration (analogous to cake washing in dead-ended filtration) for the removal of coal liquid from the solids stream. The use of these ceramic crossflow membranes overcomes the limitations of traditional polymeric crossflow membranes by having the ability to operate at elevated temperature and to withstand prolonged exposure to hydrocarbon and solvent media. In addition, CeraMem`s membrane filters are significantly less expensive than competitive ceramic membranes due to their unique construction. With these ceramic membrane filters, it may be possible to reduce the product losses associated with traditional deashing processes at an economically attractive cost. The performance of these ceramic membrane microfilters is discussed.

    The long-term objective of this work is to develop a transformational energy production technology by insitu thermal treatment of a coal seam for the production of substitute natural gas (SNG) while leaving much of the coal's carbon in the ground. This process converts coal to a high-efficiency, low-GHG emitting gas fuel. It holds the potential of providing environmentally acceptable access to previously unusable coal resources. This topical report discusses the development of experimental capabilities, the collection of available data, and the development of simulation tools to obtain process thermo-chemical and geo-thermal parameters in preparation for the eventual demonstration in a coal seam. It also includes experimental and modeling studies of CO2 sequestration.

    It has been estimated that there is 36 billion tons of coal resource potential in Indonesia. Over 21.4 billion tons is classified as low rank (lignitic) coal. The coal deposits are located mainly in Sumatra and Kalimantan. As an energy source, low rank coals are not widely used, because of their high moisture content, low calorific value and variable ash content. One of the key questions for utilizing low rank coal is whether lignite can be upgraded into another form which is more economically viable. In this study tests were carried out in a pilot plant fixed bed pyrolysis reactor unit provided with hopper, electric heater, coolers and product receivers. The yield of char, tar and gases was found to depend on temperature which also affected the composition of gas produced. Results also indicated the temperature and particle size giving maximum tar yield, gas concentration, and the atmosphere of inert nitrogen. 1 tab., 2 figs., 10 refs.

    Formation of coal seam and coal-rich zone is an integrated result of a series of factors in coal accumulation process. The coal accumulation system is an architectural aggregation of coal accumulation factors. It can be classified into 4 levels: the global coal accumulation super-system, the coal accumulation domain mega.system, the coal accumulation basin system, and the coal seam or coal seam set sub-system. The coal accumulation process is an open, dynamic, and grey system, and is meanwhile a system with such natures as aggregation, relevance, entirety, purpose-orientated, hierarchy, and environment adaptability. In this paper, we take coal accumulation process as a system to study origin of coal seam and coal-rich zone; and we will discuss a methodology of the systematic analysis of coal accumulation process. As an example, the Ordos coal basin was investigated to elucidate the application of the method of the coal accumulation system analysis.

    1994-01-01

    The Clean Coal Technology Program is a government and industry cofunded effort to demonstrate a new generation of innovative coal processes in a series of full-scale showcase`` facilities built across the country. Begun in 1986 and expanded in 1987, the program is expected to finance more than $6.8 billion of projects. Nearly two-thirds of the funding will come from the private sector, well above the 50 percent industry co-funding expected when the program began. The original recommendation for a multi-billion dollar clean coal demonstration program came from the US and Canadian Special Envoys on Acid Rain. In January 1986, Special Envoys Lewis and Davis presented their recommendations. Included was the call for a 5-year, $5-billion program in the US to demonstrate, at commercial scale, innovative clean coal technologies that were beginning to emerge from research programs both in the US and elsewhere in the world. As the Envoys said: if the menu of control options was expanded, and if the new options were significantly cheaper, yet highly efficient, it would be easier to formulate an acid rain control plan that would have broader public appeal.

    Purpose - Indiana is listed among the top ten coal states in the USA and annually mines about 35 million short tons (million tons) of coal from the vast reserves of the US Midwest Illinois Coal Basin. The implementation and commercialization of clean coal technologies is important to the economy of the state and has a significant role in the state's energy plan for increasing the use of the state's natural resources. Coal is a substantial Indiana energy resource and also has stable and relatively low costs, compared with the increasing costs of other major fuels. This indigenous energy source enables the promotion of energy independence. The purpose of this paper is to outline the significance of clean coal projects for achieving this objective. Design/methodology/approach - The paper outlines the clean coal initiatives being taken in Indiana and the research carried out at the Indiana Center for Coal Technology Research. Findings - Clean coal power generation and coal for transportation fuels (coal-to-liquids - CTL) are two major topics being investigated in Indiana. Coking coal, data compilation of the bituminous coal qualities within the Indiana coal beds, reducing dependence on coal imports, and provision of an emissions free environment are important topics to state legislators. Originality/value - Lessons learnt from these projects will be of value to other states and countries.

    Technological and economic aspects are examined for processing coal-containing waste water from brown coal preparation plants in the German Democratic Republic. In 1979, 106.8 Mm/sup 3/ of coal slurry were produced by the GDR brown coal industry, with a coal fine content ranging between 7.8 g/l and 20.4 g/l. This amounts to 2.6 Mt/y of coal which is 1% of the annual brown coal production. Technological variants of processing and utilizing coal slurry are discussed. At a number of major coal preparation plants, coal slurry is flushed into sedimentation lakes. After a 2 to 3 year drying period, a 6 to 10 m thick layer of coal is recovered. Technologies of coal slurry processing with the aim of recovering coal fines are enumerated. Equipment for these processes include, filters, centrifuges, dryers, etc. Recovered coal can be used as fuel or processed into fertilizer in combination with fly ash and other waste products. 12 references.

    Full Text Available The issues of British national identity and social cohesion have become pressing concerns within the multicultural fabric of contemporary British society. The increasing number of immigrants and their offspring, along with the maintenance of their cultural roots, seem to represent a serious defiance to social cohesion and the alleged “purity” of Britishness. A number of race related reports were produced by the official authorities to churn out the necessary steps to be followed by the British (immigrants and host community in order to keep social stability and community cohesion. Thus, the politics of community cohesion came to the fore as the neologism of contemporary British political discourse. Such new discourse of governance has been digested and processed differently by different mass media. It has been decoded, for instance, preferably by mainstream news agencies like BBC News Online. However, arguably, it is read appositionally or at best negotiatedly by ethnicity-related news agencies such as Muslim News Online. In this article, attempt has been made to adopt media discourse analysis tools to decipher the ways Muslim News Online decoded and then encoded the hegemonic official discourses of Britishness and community cohesion. A critical and interpretative approach is used to accomplish such study. The corpus of this study is primarily extracted from the website of the Muslim News Online.

    2003-12-01

    Full Text Available The essence of the British military and security formula in Palestine was the smooth establishment of the Jewish national home with minimum costs of lives and money. However, this British pro-Zionist policy created a continuous security problem, and opened the door to all possibilities of Palestinian revolts and uprisings of both national and religious nature. The British were very active in disarming the Arabs and adopted stringent measures to crush their uprisings and revolts. But, they turned a blind eye to the Jewish arms smuggling and Jewish military organizations, especially, the Hagana, which later became the backbone of the Israeli Army. During Palestinian uprisings of 1920, 1921 and 1929 against the Zionists, most of the Palestinian casualties were inflicted by the British forces despite the fact that the Palestinians avoided attacking the British. The British-Zionist cooperation reached its peak during the Palestinian revolt of 1936-1939, and took different forms, including allowing the Jews to establish a military force of twenty two thousand men under the pretext of protecting the Jewish community.

    The outcome of the British General Election to be held in just over one week's time is widely regarded as the most difficult in living memory to predict. Current polls suggest that the two main parties are neck and neck but that there will be a landslide to the Scottish Nationalist Party with that party taking most of the constituencies in Scotland. The Liberal Democrats are forecast to loose more than half their seats and the fringe parties of whom the UK Independence Party is the biggest are simply unknown quantities. Much of this volatility relates to long-standing and deeply rooted cultural and nationalist attitudes that relate to geographical fault lines that have been present for 500 years or more but occasionally reveal themselves, at times like this. In this paper our purpose is to raise the notion that these fault lines are critical to thinking about regionalism, nationalism and the hierarchy of cities in Great Britain (excluding Northern Ireland).

  7. Utopianism in the British evolutionary synthesis.

    Science.gov (United States)

    Esposito, Maurizio

    2011-03-01

    In this paper I propose a new interpretation of the British evolutionary synthesis. The synthetic work of J. B. S. Haldane, R. A. Fisher and J. S. Huxley was characterized by both an integration of Mendelism and Darwinism and the unification of different biological subdisciplines within a coherent framework. But it must also be seen as a bold and synthetic Darwinian program in which the biosciences served as a utopian blueprint for the progress of civilization. Describing the futuristic visions of these three scientists in their synthetic heydays, I show that, despite a number of important divergences, their biopolitical ideals could be biased toward a controlled and regimented utopian society. Their common ideals entailed a social order where liberal and democratic principles were partially or totally suspended in favor of bioscientific control and planning for the future. Finally, I will argue that the original redefinition of Darwinism that modern synthesizers proposed is a significant historical example of how Darwinism has been used and adapted in different contexts. The lesson I draw from this account is a venerable one: that, whenever we wish to define Darwinism, we need to recognize not only its scientific content and achievements but expose the other traditions and ideologies it may have supported.

  8. The Planetary Consciousness of British Travel Writers

    Henry, H.

    2013-04-01

    Global travel, advanced in the early 20th century by trains, automobiles, and airplanes, transformed modernist thought and experience. Stephen Kern has commented that in the modern period “a series of sweeping changes in technology and culture created distinctive new modes of thinking about and experiencing of time and space. Technological innovations including the telephone, wireless telegraph, x-ray, cinema, bicycle, automobile, and airplane established the material foundation for this reorientation.” (1983, pp. 1-2). Emerging travel technologies not only hurled passengers through multiple time zones in a day but also brought to the fore a global awareness regarding Earth as a globe in space and one's position on it. As early as 1909, while traveling in Florence, Virginia Woolf had noted in her diary, “It is strange how one begins to hold a globe in one's head: I can travel from Florence to Fitzroy Square on solid land all the time” (1984, p. 399). This paper traces the ways modernist British travel writers challenged England's geographical and geopolitical imagination at the turn of the 20th century through their travel narratives.

    This lab experiment illustrates the use of thermogravimetric analysis (TGA) to perform proximate analysis on a series of coal samples of different rank. Peat and coke are also examined. A total of four exercises are described. These are dry exercises as students interpret previously recorded scans. The weight percent moisture, volatile matter, fixed carbon, and ash content are determined for each sample and comparisons are made. Proximate analysis is performed on a coal sample from a local electric utility. From the weight percent sulfur found in the coal (determined by a separate procedure the Eschka method) and the ash content, students calculate the quantity of sulfur dioxide emissions and ash produced annually by a large coal-fired electric power plant.

The project was, however, aborted in October 1996 because Tianjin had been allocated a connection to domestic natural gas fields. The project did identify the suitability of coals from the Shanxi coalfields for the Coalite process and the likely market acceptability of the product. It demonstrated the necessity of establishing good contacts in the relevant industries and Ministries in China - and highlighted the benefits of an effective collaboration between three types of organisation - an investment and consultancy company with expertise in China, a UK clean coal technology company, and a local consultant. 4 apps.

    2003-07-01

    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.

    1999-01-01

    Bulgaria`s national energy strategy includes plans to restructure the energy sector by introducing competition and privatisation, to promote energy efficiency and environmental protection and to prepare the country for integration into the EU energy market. Energy prices are still under government control and coal mining is heavily subsidised. Bulgaria is a major producer of coal, all of which is consumed locally. Most of the domestic production is low quality lignite used for electricity generation. Demand for hard coal is met by imports, mainly from the former USSR and the USA. Bulgaria generates almost half of its electricity needs from coal. Total reserves of lignite are estimated at 2.5 Gt. Coal production declined between 1987 and 1991 reflecting the economic disturbance following the break up of the USSR. In 1996, production was 32 Mt. The mining industry is being restructured as Bulgaria is slowly moving from a centrally-controlled economy to a market-based economy. Environmental damage as a result of coal production has been serious in Bulgaria, due to the use of low grade high sulphur content lignite. 84 refs., 10 figs., 9 tabs.

  19. Indicators of coal metamorphism

    Energy Technology Data Exchange (ETDEWEB)

    Proskuryakov, A.E.

    1982-06-01

    Important in determining metamorphism of coal is the reliability of indicators of coalification. Both the reflection of vitrinite and emission of volatile matter have been used for this purpose. To determine which indicator more accurately characterizes metamorphism of coal, their conformity to the following demands was established: 1. uniformity in direction of change of parameters with degree of metamorphism; 2. independence of the indicator of the genetic characteristics of coal (petrographic composition, reduction and oxidation of coal); 3. sensitivity of indicator. Both indicators conform to the first requirement. Emission of volatile substance decreases and reflective capacity of vitrinite increases uniformly with degree of metamorphism. However, the reflectivity of vitrinite is not influenced by petrographic composition of coals and is less dependent on the oxidation and reduction of coal than emission of volatile matter. It is also a more sensitive indicator distinguishing more degrees of metamorphism than emission of volatile matter. Reflectivity of vitrinite is a more reliable indicator of metamorphism than emission of volatile matter. However, in many laboratories this indicator is not measured with sufficient accuracy. To correct this, measuring equipment must be standardized.

    The following report deals with the use of coal and coke during 1998. 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 Statistics Sweden have also been used. The use of steam coal for heating purposes during 1998 was 680 000 tons and somewhat lower than in 1997. The extremely high figures of 1996 were due to twice the production of electricity because of lack of waterpower. 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. During the top year 1987 coal was used in 18 hot water plants and 11 co-generation plants. During 1998 these figures are 1 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. Steel-works, however, increase their use of steam coal in order to replace the more expensive coke. The import of metallurgical coal in 1998 was 1.6 mill tons like the year before. 1.1 mill tons of coke were produced. The coke consumption in the industry was 1.4 mill tons from which 0.3 mill tons were imported. Several other plants have plans to replace the coal with forest fuels, waste fuels and NG.

    The lungs of 450 coal miners who had been studied previously in a long-term epidemiologic project at 24 British mines have been examined post-mortem for signs of dust-related fibrosis and emphysema. Reliable estimates of cumulative (working-life) exposures to respirable mine dust were available for 342 of the men. The relative frequency of emphysema increased with age at death, and both panacinar and centriacinar emphysema occurred more frequently in smokers than in nonsmokers. The proportion of subjects with any emphysema was 47% in 92 men with no palpable dust lesions, 65% in 183 with small, simple pneumoconiotic lesions, and 83% in 175 miners with massive fibrosis (PMF). The chance of finding centriacinar emphysema in those with PMF increased significantly with increasing exposure to coal dust in life (p less than 0.025). A similar but less convincing relationship was found in those with simple pneumoconiosis (p less than 0.11), but in both groups, increasing amounts of ash with a given exposure to coal reduced the probability of finding centriacinar emphysema. The occurrence of centriacinar emphysema was associated also with increasing amounts of dust retained in the lungs. A preliminary exploration of this association did not support the hypothesis that emphysematous lungs clear dust less efficiently. We conclude that the association observed between exposure to respirable coal dust and emphysema in coal miners indicates a causal relationship. However, because it can be demonstrated only for men whose lungs show some dust-related fibrosis, it is suggested that the extent and nature of such fibrosis may be a crucial factor in determining the presence of centriacinar emphysema.

    A method of extracting coal from a coal refuse pile comprises soaking the coal refuse pile with an aqueous alkali solution and distributing an oxygen-containing gas throughout the coal refuse pile for a time period sufficient to effect oxidation of coal contained in the coal refuse pile. The method further comprises leaching the coal refuse pile with an aqueous alkali solution to solubilize and extract the oxidized coal as alkali salts of humic acids and collecting the resulting solution containing the alkali salts of humic acids. Calcium hydroxide may be added to the solution of alkali salts of humic acid to form precipitated humates useable as a low-ash, low-sulfur solid fuel.

    Indonesia's fire and haze problem is increasingly being ascribed to large-scale forest conversion and land clearing activities making way for pulpwood, rubber and oil palm plantations. Fire is the cheapest tool available to small holders and plantation owners to reduce vegetation cover and prepare and fertilize extremely poor soils. Fires that escaped from agricultural burns have ravaged East Kalimantan forests on the island of Borneo during extreme drought periods in 1982-1983, 1987, 1991, 1994 and 1997-1998. Estimates based on satellite data and ground observations are that more than five million hectares were burned in East Kalimantan during the 1997/1998 dry season. Not only were the economic losses and ecological damage from these surface fires enormous, they ignited coal seams exposed at the ground surface along their outcrops.Coal fires now threaten Indonesia's shrinking ecological resources in Kutai National Park and Sungai Wain Nature Reserve. Sungai Wain has one of the last areas of unburned primary rainforest in the Balikpapan-Samarinda area with an extremely rich biodiversity. Although fires in 1997/1998 damaged nearly 50% of this Reserve and ignited 76 coal fires, it remains the most valuable water catchment area in the region and it has been used as a reintroduction site for the endangered orangutan. The Office of Surface Mining provided Indonesia with the capability to take quick action on coal fires that presented threats to public health and safety, infrastructure or the environment. The US Department of State's Southeast Asia Environmental Protection Initiative through the US Agency for International Development funded the project. Technical assistance and training transferred skills in coal fire management through the Ministry of Energy and Mineral Resource's Training Agency to the regional offices; giving the regions the long-term capability to manage coal fires. Funding was also included to extinguish coal fires as

    This conference provided an opportunity to exchange information on mine reclamation and related issues affecting coal mining in British Columbia and oil sand mining in Alberta. The reclamation of lands disturbed by mineral extraction and processing or by other industrial activity is aimed at returning the land to a level that is equivalent to its pre-industrial activity. The environmental impacts of mine development were discussed along with opportunities to rehabilitate disturbed lands using new remedial methods for soil conservation, water protection and carbon sequestration. A broad range of reclamation, restoration and remediation methods for oil sand mining, coal mining and metals in soils were also discussed. The conference featured 30 presentations, including posters, of which 9 have been catalogued separately for inclusion in this database. refs., tabs., figs.

    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{sub 2} and NO{sub x} as given by county administrations or concession boards. The cogeneration plants all have some SO{sub 2} removal system. The biggest cogeneration plant (Vaesteraas) has recently invested in a SCR NO{sub x} cleaning system. Most other plants use low NO{sub x} burners or SNR injection systems based on ammonia or urea. 2 figs, 13 tabs.

    India is the third largest producer and consumer of coal in the world. Coal generally has a high ash content, thereby requiring that it be cleaned for proper use. Technological advances now make it possible to reduce pollution considerably, even as energy use increases. However, to reduce environmental impacts, technologies for cleaning coal before combustion need to be developed. The paper focuses on the need for clean coal production and the benefits associated with it. Although the country is rich in coal reserves, the generally inferior quality of coal will lead to its depletion if it is not used cleanly. Increasing the proportion of prepared coal from the current level of less than 5% (i.e. 10-11 million tonnes per annum) of all coal consumed will lead to a massive saving. This can be achieved if new washeries are set up, preferably near the coalfields. 2 figs.

    2008-12-01

    The United Nations Intergovernmental Panel on Climate Change (IPCC) makes projections in terms of scenarios that include estimates of oil, gas, and coal production. These scenarios are defined in the Special Report on Emissions Scenarios or SRES (Nakicenovic et al., 2000). It is striking how different these scenarios are. For example, total oil production from 2005 to 2100 in the scenarios varies by 5:1 (Appendix SRES Version 1.1). Because production in some of the scenarios has not peaked by 2100, this ratio would be comparable to 10:1 if the years after 2100 were considered. The IPCC says "... the resultant 40 SRES scenarios together encompass the current range of uncertainties of future GHG [greenhouse gas] emissions arising from different characteristics of these models ..." (Nakicenovic et al., 2000, Summary for Policy Makers). This uncertainty is important for climate modeling, because it is larger than the likely range for the temperature sensitivity, which the IPCC gives as 2.3:1 (Gerard Meehl et al., 2007, the Fourth Assessment Report, Chapter 10, Global Climate Projections, p. 799). The uncertainty indicates that we could improve climate modeling if we could make a better estimate of future oil, gas, and coal production. We start by considering the two major fossil-fuel regions with substantial exhaustion, US oil and British coal. It turns out that simple normal and logistic curve fits to the cumulative production for these regions give quite stable projections for the ultimate production. By ultimate production, we mean total production, past and future. For US oil, the range for the fits for the ultimate is 1.15:1 (225- 258 billion barrels) for the period starting in 1956, when King Hubbert made his prediction of the peak year of US oil production. For UK coal, the range is 1.26:1 for the period starting in 1905, at the time of a Royal Commission on coal supplies. We extend this approach to find fits for world oil and gas production, and by a regional

    Coal liquefaction is an emerging technology receiving great attention as a possible liquid fuel source. Currently, four general methods of converting coal to liquid fuel are under active development: direct hydrogenation; pyrolysis/hydrocarbonization; solvent extraction; and indirect liquefaction. This work is being conducted at the pilot plant stage, usually with a coal feed rate of several tons per day. Several conceptual design studies have been published recently for large (measured in tens of thousands of tons per day coal feed rate) commercial liquefaction plants, and these reports form the data base for this evaluation. Products from a liquefaction facility depend on the particular method and plant design selected, and these products range from synthetic crude oils up through the lighter hydrocarbon gases, and, in some cases, electricity. Various processes are evaluated with respect to product compositions, thermal efficiency, environmental effects, operating and maintenance requirements, and cost. Because of the large plant capacities of current conceptual designs, it is not clear as to how, and on what scale, coal liquefaction may be considered appropriate as an energy source for Integrated Community Energy Systems (CES). Development work, both currently under way and planned for the future, should help to clarify and quantify the question of applicability.

  20. British sociology and public intellectuals: consumer society and imperial decline.

    2006-06-01

    The following is the lecture given for the BJS 2005 Public Sociology Debate given at the London School of Economics and Political Science on ll October 2005. This lecture on the character of British sociology provides a pretext for a more general inquiry into public intellectual life in postwar Britain. The argument put forward falls into several distinctive sections. First, British social science has depended heavily on the migration of intellectuals, especially Jewish intellectuals who were refugees from fascism. Second, intellectual innovation requires massive, disruptive, violent change. Third, British sociology did nevertheless give rise to a distinctive tradition of social criticism in which one can argue there were (typically home-grown) public intellectuals. The main theme of their social criticism was to consider the constraining and divisive impact of social class, race and gender on the enjoyment of expanding social citizenship. Fourth, postwar British sociology came to be dominated by the analysis of an affluent consumer society. Finally, the main failure of British sociology in this postwar period was the absence of any sustained, macro-sociological analysis of the historical decline of Britain as a world power in the twentieth century.

    The growing interest in coal exploration and development in southeastern British Columbia can be attributed to the favourable price outlooks for metallurgical coal and coalbed methane (CBM). The East Kootenay contains 3 coalfields, namely the Crowsnest, Elk Valley and Flathead, which combined contain over 50 billion tonnes of coal and 19 trillion cubic feet of CBM resource. Cline Mining is in the pre-application phase of the development of a metallurgical coal mine, and BP Energy Canada plans to begin exploration of a $3 billion CBM project in the Crowsnest Coal field. However, future development may be affected by the breakdown of negotiations between Montana and British Columbia regarding a joint environmental framework for the Flathead River ecosystem, an area in southern East Kootenay that spans both Montana and British Columbia. Development may also be affected by a United States statute known as Pakootas v. Teck Cominco Metals, in which the United States Environmental Protection Agency had ordered Teck Cominco to carry out a remediation feasibility study on slag discharged from a Canadian smelter up the Columbia River that had leached heavy metals in U.S. waters. This article described the political pressure that coal and CBM companies will face from the various forces organized against Flathead development. Although Montana does not have any legal means by which it can stop coal and CBM projects in British Columbia on a case-by-case basis, Montana could request that the State Department refer a question to the International Joint Committee, which could lead to a report of recommendations. Such a report could act as a catalyst to various project opponents. 6 refs., 2 figs.

The last meeting of the French gas association (AFG) aimed at shading light and at supplying some elements of analysis necessary for the correct understanding of the British gas market problem. The volatility of the spot market, its capacity to adjust the supply and demand and the role of long-term contracts in ensuring the security of supplies were explained and debated by a various panel of high level orators: P.W. Wright (Sheffield univ.), J. Harvard (deputy director, Gas Markets, Dept. of trade and industry), S. Caudron (manager business development, Statoil) and P. Vedrenne (managing director, Gaselys).

    Decision Support Aids (DSAs) have been widely used throughout industry and one (known as Table 7) is available to support British Army Medical Officers (MOs) grade soldiers against the Joint Medical Employment Standards. It is unknown how useful this DSA is in practice. An electronic questionnaire was distributed to British Army MOs working within Defence Primary Care facilities enquiring about MOs views on the usefulness of the DSA. Although the response rate was low, informative data were obtained. Between a half and a third of respondents felt that their judgement was affected in the application of the grading system when there were career implications to the grading MOs felt that the DSA allowed subjectivity in the grading. The results of this research suggest that although minor changes to Table 7 may improve service provision, an improvement in training in the application of Table 7 would be of greater benefit to the quality of occupational health service provision in the British Army.

    2011-01-01

    A further understanding of the self-heating of coal was obtained by investigating the crossing point temperature (CPT) of different ranks of coal. The tests were carried out using a self-designed experimental system for coal self-heating. 50 g (±0.01 g) of coal particles ranging from 0.18 mm to 0.38 mm in size were put into a pure copper reaction vessel attached to the center of a temperature programmed enclosure. The temperature program increased the temperature at a rate of 0.8 ℃/min. Dry air was permitted to flow into the coal reaction vessel at different rates. The surrounding temperature and the coal temperature were monitored by a temperature logger. The results indicate that CPT is affected by coal rank, moisture, sulfur,and the experimental conditions. Higher ranked coals show higher CPT values. A high moisture content causes a delay phenomenon during the self-heating of the coal. Drying at 40 ℃ decreases the effects of moisture. The reactivity of sulfur components in the coal is low under dry and low-temperature conditions.These components form a film that covers the coal surface and slightly inhibits the self-heating of the coal.The flow rate of dry air, and the heating rate of the surroundings, also affect the self-heating of the coal. The most appropriate experimental conditions for coal samples of a given weight and particle size were determined through contrastive analysis. Based on this analysis we propose that CPTs be determined under the same, or nearly the same conditions, for evaluation of the spontaneous combustion of coal.

    It is established experimentally using 1H NMR wide line spectroscopy that methane can exist in coals not only in open or closed porosity and fracture systems but also in solid solutions in coal substance, in particular, under methane pressure 2 MPa or higher. Methane dissolved in coal minerals reversibly modifies their lattice parameters as determined from X-ray diffraction analysis. Co-existence of these methane forms in fossil coals causes multi-step desorption kinetics. It is shown experimentally that the long-term latent methane desorption is effected mainly by closed porosity, which in turn is determined by coal rank. 21 refs., 3 figs., 2 tabs.

    Despite the economic importance of coal to the Australian economy, detailed studies of controls on variation in coal type are remarkably few. However, important contributions have been made in the understanding of coal facies development. Tertiary lignite deposits of the Gippsland Basin provide key insights into the development of lithotype cyclicity and its relationship to relative sea-level changes, with individual paling-up cycles being correlated to parasequences. Studies of Permian hard coals have identified relationships between coal type and surrounding sediments. Unfortunately, these relationships have been widely over-interpreted in a manner that has diminished their real value.

In this regard, we present a brief analysis and display on historical view, as being emblematic of the issue exposed.Multiculturalism is considered as the only solution for the reconciliation of the two perspectives: Englishness andBritishness. Multiculturalism tries to solve the old syntagma of “us and the other ” by replacing it with a slightly different approach to this age old relationship. Contemporary multiculturalism appears as a form of cultural or rejuvenation, which is necessary for any given culture to continue existing.

This had a tremendous impact on the psyche of the colonized and was a determinant factor in shaping the nature of the relationship between the colonizers and colonized before and after independence. Therefore, this paper seeks to juxtapose the colonial behaviour of two colonial powers, French and British, in two major colonies, Algeria and India.

    The U.S. Geological Survey (USGS) conducted the National Coal Quality Inventory (NaCQI) between 1999 and 2005 to address a need for quality information on coals that will be mined during the next 20-30 years. Collaboration between the USGS, State geological surveys, universities, coal burning utilities, and the coal mining industry plus funding support from the Electric Power Research Institute (EPRI) and the U.S. Department of Energy (DOE) permitted collection and submittal of coal samples for analysis. The chemical data (proximate and ultimate analyses; major, minor and trace element concentrations) for 729 samples of raw or prepared coal, coal associated shale, and coal combustion products (fly ash, hopper ash, bottom ash and gypsum) from nine coal producing States are included. In addition, the project identified a new coal reference analytical standard, to be designated CWE-1 (West Elk Mine, Gunnison County, Colorado) that is a high-volatile-B or high-volatile-A bituminous coal with low contents of ash yield and sulfur, and very low, but detectable contents of chlorine, mercury and other trace elements.

    Future Integrated Coal Gasification Combined Cycle (ICGCC) power plants will have superior environmental performance and efficiency. The Shell Coal Gasification Process (SCGP) is a clean coal technology, which can convert a wide range of coals into clean syngas for high efficiency electricity generation in an ICGCC plant. SCGP flexibility has been demonstrated for high-rank bituminous coals to low rank lignites and petroleum coke, and the process is well suited for combined cycle power generation, resulting in efficiencies of 42 to 46% (LHV), depending on choice of coal and gas turbine efficiency. In the Netherlands, a 250 MWe coal gasification combined cycle plant based on Shell technology has been built by Demkolec, a development partnership of the Dutch Electricity Generating Board (N.V. Sep). The construction of the unit was completed end 1993 and is now followed by start-up and a 3 year demonstration period, after that the plant will be part of the Dutch electricity generating system.

    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.

    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.

    This report contains results of a coordinated, multi-laboratory investigation of coal devolatilization. Data is reported pertaining to the devolatilization for bituminous coals over three orders of magnitude in apparent heating rate (100 to 100,000 + {degree}C/sec), over two orders of magnitude in particle size (20 to 700 microns), final particle temperatures from 400 to 1600{degree}C, heat transfer modes ranging from convection to radiative, ambient pressure ranging from near vacuum to one atmosphere pressure. The heat transfer characteristics of the reactors are reported in detail. It is assumed the experimental results are to form the basis of a devolatilization data base. Empirical rate expressions are developed for each phase of devolatilization which, when coupled to an awareness of the heat transfer rate potential of a particular devolatilization reactor, indicate the kinetics emphasized by a particular system reactor plus coal sample. The analysis indicates the particular phase of devolatilization that will be emphasized by a particular reactor type and, thereby, the kinetic expressions appropriate to that devolatilization system. Engineering rate expressions are developed from the empirical rate expressions in the context of a fundamental understanding of coal devolatilization developed in the course of the investigation. 164 refs., 223 figs., 44 tabs.

    1992-01-01

    This final report presents the research work carried out on the Coal Surface Control for Advanced Physical Fine Coal Cleaning Technologies project, sponsored by the US Department of Energy, Pittsburgh Energy Technology Center (DOE/PETC). The project was to support the engineering development of the selective agglomeration technology in order to reduce the sulfur content of US coals for controlling SO[sub 2] emissions (i.e., acid rain precursors). The overall effort was a part of the DOE/PETCs Acid Rain Control Initiative (ARCI). The overall objective of the project is to develop techniques for coal surface control prior to the advanced physical fine coal cleaning process of selective agglomeration in order to achieve 85% pyrite sulfur rejection at an energy recovery greater than 85% based on run-of-mine coal. The surface control is meant to encompass surface modification during grinding and laboratory beneficiation testing. The project includes the following tasks: Project planning; methods for analysis of samples; development of standard beneficiation test; grinding studies; modification of particle surface; and exploratory R D and support. The coal samples used in this project include three base coals, Upper Freeport - Indiana County, PA, Pittsburgh NO. 8 - Belmont County, OH, and Illinois No. 6 - Randolph County, IL, and three additional coals, Upper Freeport - Grant County- WV, Kentucky No. 9 Hopkins County, KY, and Wyodak - Campbell County, WY. A total of 149 drums of coal were received.

  12. Hydrothermal pretreatment of coal

    Energy Technology Data Exchange (ETDEWEB)

    Ross, D.S.

    1989-12-21

    We have examined changes in Argonne Premium samples of Wyodak coal following 30 min treatment in liquid water at autogenous pressures at 150{degrees}, 250{degrees}, and 350{degrees}C. In most runs the coal was initially dried at 60{degrees}C/1 torr/20 hr. The changes were monitored by pyrolysis field ionization mass spectrometry (py-FIMS) operating at 2.5{degrees}C/min from ambient to 500{degrees}C. We recorded the volatility patterns of the coal tars evolved over that temperature range, and in all cases the tar yields were 25%--30% of the starting coal on mass basis. There was essentially no change after the 150{degrees}C treatment. Small increases in volatility were seen following the 250{degrees}C treatment, but major effects were seen in the 350{degrees} work. The tar quantity remained unchanged; however, the volatility increased so the temperature of half volatility for the as-received coal of 400{degrees}C was reduced to 340{degrees}C. Control runs with no water showed some thermal effect, but the net effect from the presence of liquid water was clearly evident. The composition was unchanged after the 150{degrees} and 250{degrees}C treatments, but the 350{degrees} treatment brought about a 30% loss of oxygen. The change corresponded to loss of the elements of water, although loss of OH'' seemed to fit the analysis data somewhat better. The water loss takes place both in the presence and in the absence of added water, but it is noteworthy that the loss in the hydrothermal runs occurs at p(H{sub 2}O) = 160 atm. We conclude that the process must involve the dehydration solely of chemically bound elements of water, the dehydration of catechol is a specific, likely candidate.

    Dux, C.D.; Kroh, G.C.; VanKuiken, J.C.

    1977-08-01

    The Argonne Coal Market Model was developed as part of the National Coal Utilization Assessment, a comprehensive study of coal-related environmental, health, and safety impacts. The model was used to generate long-term coal market scenarios that became the basis for comparing the impacts of coal-development options. The model has a relatively high degree of regional detail concerning both supply and demand. Coal demands are forecast by a combination of trend and econometric analysis and then input exogenously into the model. Coal supply in each region is characterized by a linearly increasing function relating increments of new mine capacity to the marginal cost of extraction. Rail-transportation costs are econometrically estimated for each supply-demand link. A quadratic programming algorithm is used to calculate flow patterns that minimize consumer costs for the system.

    Coal bed methane (CBM) is a relatively clean source of energy but current CBM production techniques have not sustained long-term production or produced enough methane to remain economically practical with lower natural gas prices. Enhancement of the in situ microbial community that actively generates CBM with the addition of specific nutrients could potentially sustain development. CBM production more than doubled from native microbial populations from Powder River Basin (PRB) coal beds, when yeast extract and several individual components of yeast extract (proteins and amino acids) were added to laboratory microcosms. Microbial populations capable of hydrogenotrophic (hydrogen production/utilization) methanogenesis were detected in situ and under non-stimulated conditions. Stimulation with yeast extract caused a shift in the community to microorganisms capable of acetoclastic (acetate production/utilization) methanogenesis. Previous isotope analysis from CBM production wells indicated a similar microbial community shift as observed in stimulation experiments: hydrogenotrophic methanogenesis was found throughout the PRB, but acetoclastic methanogenesis dominated major recharge areas. In conjunction, a high proportion of cyanobacterial and algal SSU rRNA gene sequences were detected in a CBM well within a major recharge area, suggesting that these phototrophic organisms naturally stimulate methane production. In laboratory studies, adding phototrophic (algal) biomass stimulated CBM production by PRB microorganisms similarly to yeast extract (~40μg methane increase per gram of coal). Analysis of the British thermal unit (BTU) content of coal from long-term incubations indicated >99.5% of BTU content remained after CBM stimulation with either algae or yeast extract. Biomimicry of in situ algal CBM stimulation could lead to technologies that utilize coupled biological systems (photosynthesis and methane production) that sustainably enhance CBM production and generate

    Coal fires occur in underground natural coal seams, in exposed surface seams, and in coal storage or waste piles. The fires ignite through spontaneous combustion or natural or anthropogenic causes. They are reported from China, India, USA, South Africa, Australia, and Russia, as well as many other countries. Coal fires lead to loss of a valuable resource (coal), the emission of greenhouse-relevant and toxic gases, and vegetation deterioration. A dangerous aspect of the fires is the threat to local mines, industries, and settlements through the volume loss underground. Surface collapse in coal fire areas is common. Thus, coal fires are significantly affecting the evolution of the landscape. Based on more than a decade of experience with in situ mapping of coal fire areas worldwide, a general classification system for coal fires is presented. Furthermore, coal seam fire geomorphology is explained in detail. The major landforms associated with, and induced by, these fires are presented. The landforms include manifestations resulting from bedrock surface fracturing, such as fissures, cracks, funnels, vents, and sponges. Further manifestations resulting from surface bedrock subsidence include sinkholes, trenches, depressions, partial surface subsidence, large surface subsidence, and slides. Additional geomorphologic coal fire manifestations include exposed ash layers, pyrometamorphic rocks, and fumarolic minerals. The origin, evolution, and possible future development of these features are explained, and examples from in situ surveys, as well as from high-resolution satellite data analyses, are presented. The geomorphology of coal fires has not been presented in a systematic manner. Knowledge of coal fire geomorphology enables the detection of underground coal fires based on distinct surface manifestations. Furthermore, it allows judgments about the safety of coal fire-affected terrain. Additionally, geomorphologic features are indicators of the burning stage of fires

  13. Role of coal water mixture in utility coal conversion

    1984-05-01

    To indicate the role of coal water mixtures (CWM) in utility coal conversions, the pertinent technical, economic, environmental, and regulatory factors involved in CWM conversion are reviewed. CWM technology provides an attractive option for utility companies to convert to coal. There appear to be no major technical problems in CWM production and use that cannot be overcome. Environmental considerations, however, play an important role in utilities' decisions to convert to coal. In general, coal conversions would be seriously impeded if the installation of flue gas desulfurization units cannot be avoided, as it now can because of the DOE program, and they are also inhibited by present uncertainties regarding impending acid rain regulations. Preliminary estimates of the economics of conversion seem attractive; however, site-specific evaluation is needed to justify conversion in a given situation. Although conversion to pulverized coal appears competitive with that to CWM, some non-economic factors tend to favor CWM over PC.

    1990-01-01

    The objective of this research project is to understand the fundamentals involved in the flotation and flocculation of coal and oxidized coals and elucidate mechanisms by which surface interactions between coal and various reagents enhance coal beneficiation. An understanding of the nature of the heterogeneity of coal surfaces arising from the intrinsic distribution of chemical moieties is fundamental to the elucidation of mechanism of coal surface modification and its role in interfacial processes such as flotation, flocculation and agglomeration. A new approach for determining the distribution in surface properties of coal particles was developed in this study and various techniques capable of providing such information were identified. Distributions in surface energy, contact angle and wettability were obtained using novel techniques such as centrifugal immersion and film flotation. Changes in these distributions upon oxidation and surface modifications were monitored and discussed. An approach to the modelling of coal surface site distributions based on thermodynamic information obtained from gas adsorption and immersion calorimetry is proposed. Polyacrylamide and dodecane was used to alter the coal surface. Methanol adsorption was also studied. 62 figs.

    Coal will be a dominant energy source in both developed and developing countries for at least the first half of the 21st century. Environmental problems associated with coal, before mining, during mining, in storage, during combustion, and postcombustion waste products are well known and are being addressed by ongoing research. The connection between potential environmental problems with human health is a fairly new field and requires the cooperation of both the geoscience and medical disciplines. Three research programs that illustrate this collaboration are described and used to present a range of human health problems that are potentially caused by coal. Domestic combustion of coal in China has, in some cases, severely affected human health. Both on a local and regional scale, human health has been adversely affected by coals containing arsenic, fluorine, selenium, and possibly, mercury. Balkan endemic nephropathy (BEN), an irreversible kidney disease of unknown origin, has been related to the proximity of Pliocene lignite deposits. The working hypothesis is that groundwater is leaching toxic organic compounds as it passes through the lignites and that these organics are then ingested by the local population contributing to this health problem. Human disease associated with coal mining mainly results from inhalation of particulate matter during the mining process. The disease is Coal Worker's Pneumoconiosis characterized by coal dust-induced lesions in the gas exchange regions of the lung; the coal worker's "black lung disease". ?? 2002 Elsevier Science B.V.

    Our current efforts to develop clean coal technology emphasize the advantages of enzymatic desulfurization techniques and have specifically addressed the potential of using partially-purified extracellular microbial enzymes or commercially available enzymes. Our work is focused on the treatment of model'' organic sulfur compounds such as dibenzothiophene (DBT) and ethylphenylsulfide (EPS). Furthermore, we are designing experiments to facilitate the enzymatic process by means of a hydrated organic solvent matrix.

    During the second half of the 1990's Coal Bed Methane (CBM) production increased dramatically nationwide to represent a significant new source of income and natural gas for many independent and established producers. Matching these soaring production rates during this period was a heightened public awareness of environmental concerns. These concerns left unexplained and under-addressed have created a significant growth in public involvement generating literally thousands of unfocused project comments for various regional NEPA efforts resulting in the delayed development of public and fee lands. The accelerating interest in CBM development coupled to the growth in public involvement has prompted the conceptualization of this project for the development of a CBM Primer. The Primer is designed to serve as a summary document, which introduces and encapsulates information pertinent to the development of Coal Bed Methane (CBM), including focused discussions of coal deposits, methane as a natural formed gas, split mineral estates, development techniques, operational issues, producing methods, applicable regulatory frameworks, land and resource management, mitigation measures, preparation of project plans, data availability, Indian Trust issues and relevant environmental technologies. An important aspect of gaining access to federal, state, tribal, or fee lands involves education of a broad array of stakeholders, including land and mineral owners, regulators, conservationists, tribal governments, special interest groups, and numerous others that could be impacted by the development of coal bed methane. Perhaps the most crucial aspect of successfully developing CBM resources is stakeholder education. Currently, an inconsistent picture of CBM exists. There is a significant lack of understanding on the parts of nearly all stakeholders, including industry, government, special interest groups, and land owners. It is envisioned the Primer would being used by a variety of

    This investigation was undertaken to determine the fracture toughness and tensile strength of coal and to correlate these with the grindability of the coals in order to understand the fracture mechanics behaviour of coal. Results showed statistical relationships for the dependence of fracture toughness on the tensile strength of coal and between the fracture toughness and the Hardgrove Grindability Index. Softer coals have a lower fracture toughness value as coal is a brittle material. 16 references.

    In 1999, the USGS initiated the National Coal Quality Inventory (NaCQI) project to address a need for quality information on coals that will be mined during the next 20-30 years. At the time this project was initiated, the publicly available USGS coal quality data was based on samples primarily collected and analyzed between 1973 and 1985. The primary objective of NaCQI was to create a database containing comprehensive, accurate and accessible chemical information on the quality of mined and prepared United States coals and their combustion byproducts. This objective was to be accomplished through maintaining the existing publicly available coal quality database, expanding the database through the acquisition of new samples from priority areas, and analysis of the samples using updated coal analytical chemistry procedures. Priorities for sampling include those areas where future sources of compliance coal are federally owned. This project was a cooperative effort between the U.S. Geological Survey (USGS), State geological surveys, universities, coal burning utilities, and the coal mining industry. Funding support came from the Electric Power Research Institute (EPRI) and the U.S. Department of Energy (DOE).

    Coal plays an essential role in our global energy mix, particularly for power generation; and through that to the alleviation of energy poverty. The use of coal continues to grow rapidly and will continue, together with other fuels, to support world economic and social development particularly in rapidly developing world economies such as China and India. The purpose of this paper is to highlight for policy makers the value of coal to world economic and social development and so encourage development of a policy environment that will allow the coal and electricity industries to make the necessary investments in production capacity and CO2 emissions reduction technologies.

    The Energy Information Administration (EIA) initiated the Coal Reserves Data Base (CRDB) Program in October, 1990 in order to update and improve the inherent applicability of EIA's national coal reserves database. Currently, EIA's database is derived from the demonstrated reserve base (DRB) of coal, a compilation of data from published sources, unified by adherence to standardized physical criteria of minability, but never intended for the detailed coal supply and policy analyses demanded today. The CRDB Program is designed to engage the expertise available at State geological surveys in compiling best current State-level estimates of both quantities and quality of available coal reserves through cooperative agreements with EIA. The CRDB emphasizes integration of more data on coal quality, use of data from unpublished sources, cooperation with industry and other government sources, and flexibility of criteria to take into account local accessibility and mining conditions and utilize computerized geographic information systems or coal resource software. The results of pilot projects in Ohio and Wyoming are summarized. Areas nominated for support in the program include 15 additional priority coal regions in 14 States, which comprise 95 percent of the current reserve estimates and most of the coal-bearing areas of low sulfur potential. 8 refs., 3 figs., 3 tabs.

    Full Text Available By 1960, Britain’s once-thriving Music Hall industry was virtually dead. Theatres with their faded notions of Empire gave way to Cinema and the threat of Television. Where thousands once linked arms singing popular songs, watch acrobatics, see feats of strength, and listen to risqué jokes, now the echoes of those acts lay as whispers amongst the stalls’ threadbare seats. The Halls flourished in the 19th Century, but had their origins in the taverns of the 16th and 17th Centuries. Minstrels plied their trade egged on by drunken crowds. As time passed, the notoriety of the Music Hall acts and camaraderie produced grew. Entrepreneurial businessman tapped into this commerciality and had purpose-built status symbol theatres to provide a ‘home’ for acts and punters. With names like The Apollo giving gravitas approaching Olympian ideals, so the owners basked in wealth and glory. The Music Hall became the mass populist entertainment for the population. Every town had one, where everyone could be entertained by variety acts showing off the performers’ skills. The acts varied from singers, joke-tellers, comics, acrobats, to dancers. They all aimed to entertain. They enabled audiences to share a symbiotic relationship with one another; became recruitment officers for the Army; inspired War Poets; showed short films; and they and the halls reflected both the ideals and foibles of their era. By using Raymond Williams’ structures of feeling as its cornerstone, the article will give a brief history of the halls, whilst providing analysis into how they grew into mass populist entertainment that represented British culture. Case studies of famous artistes are given, plus an insight into how Music Hall segued into radio, film and television.

    The Indiana coal field forms the eastern edge of the eastern interior coal basin, which is near some of the most densely populated and highly productive manufacturing areas of the United States. (See fig. 1. ) For this reason Indiana coal reserves are an important State and National asset. In dollar value the coal mining industry is the largest of Indiana's natural-resource-producing industries. The total value of coil production for the year 1950 was more than 100 million dollars, or more than that of all other natural-resource industries in the State combined. As estimated herein, the original coal reserves of Indiana total 37,293 million tons, of which 27,320 million tons is contained in beds more than 42 inches thick; 7,632 million tons in beds 28 to 49. inches thick; and 2,341 million tons in beds 14 to 28 inches thick. The remaining reserves as of January 1951, total 35,806 million tons, of which 18,779 million tons is believed to be recoverable. The distribution of the reserves in these several categories is summarized by counties in table 1. Of the total original reserves of 37,293 million tons, 6,355 million tons can be classified as measured; 8,657 million tons as indicated; and 22,281 million tons as inferred. Strippable reserves constitute 3,524 million tons, or 9.5 percent of the total original reserves. The distribution of the strippable and nonstrippable original reserves is summarized in tables 2 and 3 by counties and by several categories, according to the thickness of the beds and the relative abundance and reliability of the information available for preparing the estimates. The distribution of the estimated 18,779 million tons of recoverable strippable and nonstrippable reserves in Indiana is further summarized by counties in table 4, and the information is presented graphically in figures 2 and 3. The tables i to 4 and figures 2 and 3 include beds in the 14- to 28-inch category, because thin beds have been mined in many places. However, many

    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.

    Full Text Available Mycobacterium malmoense was first described in northern Europe and the United Kingdom in 1977. Since then, reports have appeared with increasing frequency. Cases have, however, rarely been reported from the United States, and, until now, none have been reported in Canada. This may reflect either true low prevalence of the disease or underdiagnosis by laboratories due to slow growth of the organism. This report describes a case of pulmonary disease caused by M malmoense in a 44-year-old man from British Columbia who was successfully treated with an 18-month course of conventional antituberculous drugs combined with a macrolide. This is the first report of this disease in British Columbia and, to our knowledge, in Canada.

    This presentation discussed wind energy developments in British Columbia (BC). There are currently more than 5000 MW of wind power development activities in British Columbia, but only 325 MW of wind power purchase agreements (PPAs). Various renewable portfolio standards and greenhouse gas (GHG) initiatives are now being use to create demand for additional renewable energy development in the northwestern United States. Studies have demonstrated that BC wind export initiatives have the potential to deliver wind power to markets in the Pacific northwest. Canadian transmission export proposals are now examining methods of bringing renewable energy to areas with high load demands. However, the United States has more than 240,000 MW of proposed wind projects for key markets in the northwestern region. It was concluded that activities in United States wind development are now posing a challenge to Canadian wind energy exporters. Various transmission projects in the United States are now looking at developing renewable energy sources close to BC. tabs., figs.

    Full Text Available This paper argues that rural regions of British Columbia, Canada, are currently the subject of a radical political-economic experiment dismantling traditional Fordist and Keynesian approaches to economic development and replacing them with neoliberal strategies. This experiment targets both corporate resource economies and local or community-based economies. The paper argues that current reforms aim to enhance flexibility in major resource sectors (particularly in forestry by "liberating" corporate actors from traditional obligations to environment, labour, and communities. This strategy is buttressed by concurrent reforms to community development policies to promote "entrepreneurial" forms of development that (it is assumed can be achieved independently of the dominant resource economy. Using field research from several case communities in coastal British Columbia, the paper argues that these developments are having a strong impact on traditional economic structures and practices, as neoliberal reforms seek to disaggregate corporate and community-level economies.

    2010-01-01

    CoalVal is a menu-driven Windows program that produces cost-of-mining analyses of mine-modeled coal resources. Geological modeling of the coal beds and some degree of mine planning, from basic prefeasibility to advanced, must already have been performed before this program can be used. United States Geological Survey mine planning is done from a very basic, prefeasibility standpoint, but the accuracy of CoalVal's output is a reflection of the accuracy of the data entered, both for mine costs and mine planning. The mining cost analysis is done by using mine cost models designed for the commonly employed, surface and underground mining methods utilized in the United States. CoalVal requires a Microsoft Windows? 98 or Windows? XP operating system and a minimum of 1 gigabyte of random access memory to perform operations. It will not operate on Microsoft Vista?, Windows? 7, or Macintosh? operating systems. The program will summarize the evaluation of an unlimited number of coal seams, haulage zones, tax entities, or other area delineations for a given coal property, coalfield, or basin. When the reader opens the CoalVal publication from the USGS website, options are provided to download the CoalVal publication manual and the CoalVal Program. The CoalVal report is divided into five specific areas relevant to the development and use of the CoalVal program: 1. Introduction to CoalVal Assumptions and Concepts. 2. Mine Model Assumption Details (appendix A). 3. CoalVal Project Tutorial (appendix B). 4. Program Description (appendix C). 5. Mine Model and Discounted Cash Flow Formulas (appendix D). The tutorial explains how to enter coal resource and quality data by mining method; program default values for production, operating, and cost variables; and ones own operating and cost variables into the program. Generated summary reports list the volume of resource in short tons available for mining, recoverable short tons by mining method; the seam or property being mined

    2004-11-01

    The recovery of fine clean coal from waste streams using column flotation is recognized as an efficient and economical technique. However, due to the low percent solids (around 3% by weight) found in these fine waste slurries, the flotation columns have low capacities and are, thus, underutilized. In this study, a 3% (by weight) solids suspension of Upper Freeport coal was flocculated with polymers and concentrated to 10% (by weight) solids. The flocculated slurry was then floated using 250 g/t No. 2 fuel oil and 250 g/t MIBC, which provided a clean coal with 12% ash at an 80% yield. The results showed that flocculated coal could be floated effectively. Zeta potential and contact-angle data showed that the presence of polymer on the surface of the coal did not affect its hydrophobicity, and in some cases it improved the hydrophobicity as indicated by larger contact angles.

    Coal bursts involve the sudden, violent ejection of coal or rock into the mine workings. They are almost always accompanied by a loud noise, like an explosion, and ground vibration. Bursts are a particular haz-ard for miners because they typically occur without warning. Despite decades of research, the sources and mechanics of these events are not well understood, and therefore they are difficult to predict and control. Experience has shown, however, that certain geologic and mining factors are associated with an increased likelihood of a coal burst. A coal burst risk assessment consists of evaluating the degree to which these risk factors are present, and then identifying appropriate control measures to mitigate the hazard. This paper summarizes the U.S. and international experience with coal bursts, and describes the known risk factors in detail. It includes a framework that can be used to guide the risk assessment process.

    Malaysia is a regular participant in world coal trade. Coal production is a modest 1 Mt/y but, as an importer, the country trades some 30 Mt/y. As one of ASEAN's most prosperous economies, the expected growth in electricity demand is inevitable. For many years the country has been dependent on gas-fired power, much of which is in the form of expensive single cycle gas turbines. However, coal-fired power has emerged as an important provider of power in a country desperate to improve its energy security. This report looks at how coal-fired power has developed, and examines the current technologies deployed in the country. It is the fourth in a series of reports by the lEA Clean Coal Centre on ASEAN countries, following Indonesia, Thailand and Vietnam. 35 refs., 14 figs., 4 tabs.

    China’s energy supply heavily relies on coal and China’s coal resource and water resource has a reverse distribution. The problem of water shortages restricts the applications of wet coal beneficiation technologies in drought regions. The present situation highlights the significance and urgency of developing dry beneficiation technologies of coal. Besides, other countries that produce large amounts of coal also encounter serious problem of lack of water for coal beneficiation, such as American, Australia, Canada, South Africa, Turkey and India. Thus, dry coal beneficiation becomes the research hot-points in the field of coal cleaning worldwide in recent years. This paper systematically reviewed the promising research efforts on dry coal beneficiation reported in literature in last 5 years and discussed the progress in developments of dry coal beneficiation worldwide. Finally, we also elaborated the prospects and the challenges of the development of dry coal beneficiation.

    Murray, J. W.

    2009-05-01

    Research on future climate change is driven by the family of scenarios developed for the IPCC assessment reports. These scenarios create projections of future energy demand using different story lines consisting of government policies, population projections, and economic models. None of these scenarios consider resources to be limiting. In many of these scenarios oil production is still increasing to 2100. Resource limitation (in a geological sense) is a real possibility that needs more serious consideration. The concept of 'Peak Oil' has been discussed since M. King Hubbert proposed in 1956 that US oil production would peak in 1970. His prediction was accurate. This concept is about production rate not reserves. For many oil producing countries (and all OPEC countries) reserves are closely guarded state secrets and appear to be overstated. Claims that the reserves are 'proven' cannot be independently verified. Hubbert's Linearization Model can be used to predict when half the ultimate oil will be produced and what the ultimate total cumulative production (Qt) will be. US oil production can be used as an example. This conceptual model shows that 90% of the ultimate US oil production (Qt = 225 billion barrels) will have occurred by 2011. This approach can then be used to suggest that total global production will be about 2200 billion barrels and that the half way point will be reached by about 2010. This amount is about 5 to 7 times less than assumed by the IPCC scenarios. The decline of Non-OPEC oil production appears to have started in 2004. Of the OPEC countries, only Saudi Arabia may have spare capacity, but even that is uncertain, because of lack of data transparency. The concept of 'Peak Coal' is more controversial, but even the US National Academy Report in 2007 concluded only a small fraction of previously estimated reserves in the US are actually minable reserves and that US reserves should be reassessed using modern methods. British coal production can be

    If travel has been one of the leitmotifs of Western imagination, Robinson Crusoe has certainly been one of its foremost incarnations. This British Ulysses foretold the global village, but also its problems. He predicted the end of distance, but also the triumph of isolation and anaesthetized loneliness. This paper provides an overview of the connections between Defoe's narrative and the new science and explores two versions of the story by two contemporary writers, Julio Cortazar and John Maxwell Coetzee.

    Homeopathy is being attacked by the British media. These attacks draw support from irresponsible and unjustified claims by certain teachers of homeopathy. Such claims include the use of 'dream' and 'imaginative' methods for provings. For prescribing some such teachers attempt to replace the laborious process of matching symptom picture and remedy with spurious theories based on 'signatures', sensations and other methods. Other irresponsible claims have also been made. These "new ideas" risk destroying the principles, theory, and practice of homeopathy.

    2016-01-01

    Seagrass ecosystems face widespread threat from reduced water quality, coastal development and poor land use. In recent decades, their distribution has declined rapidly, and in the British Isles, this loss is thought to have been extensive. Given increasing knowledge of how these ecosystems support fisheries production, the understanding of their potential rapid loss, and the difficulty in restoring them, it is vital we develop an understanding of the risks they are under, so that management actions can be developed accordingly. Developing an understanding of their environmental status and condition is therefore critical to their long-term management. This study provided, to our knowledge, the first examination of the environmental health of seagrass meadows around the British Isles. This study used a bioindicator approach and involved collecting data on seagrass density and morphology alongside analysis of leaf biochemistry. Our study provides, to the best of our knowledge, the first strong quantitative evidence that seagrass meadows of the British Isles are mostly in poor condition in comparison with global averages, with tissue nitrogen levels 75% higher than global values. Such poor status places their long-term resilience in doubt. Elemental nutrient concentrations and morphological change suggest conditions of excess nitrogen and probable low light, placing many of the meadows sampled in a perilous state, although others, situated away from human populations were perceived to be healthy. Although some sites were of a high environmental health, all sites were considered at risk from anthropogenic impacts, particularly poor water quality and boating-based disturbances. The findings of this study provide a warning of the need to take action, with respect to water quality and disturbance, to prevent the further loss and degradation of these systems across the British Isles.

    Pakistan is endued with 185 billion tons colossal reserves of coal, but only 7.89 % of the country total energy requirements are met by coal. Most of the Pakistani coal reserves are sub-bituminous or lignitic in nature and contain 3-12 % sulphur. Existence of sulphur compounds in coal limits its industrial application due to environmental as well as technical problems. However, coal biotechnology can emerge as panacea for upgrading the huge reserves of coal in Pakistan. In general, coal biotechnology refers to biodesulphurization, biosolubilization and biogasification of coal. NIBGE has long term interests in the field of coal bioprocessing for tapping prime resources of indigenous coal. In NIBGE, lab scale experiments for coal biodesulphurization led to 90% efficiency in sulphur removal. Heap leaching was also carried out at the level of 10 and 20 tons coal heaps with 60% sulphur removal efficiency. Furthermore, a prototype of 300 tons coal heap was set up with a local cement industry and 75% microbial desulphurization was achieved. The league of indigenously isolated chemolithotrophic bacteria was involved in coal desulphurization. On the other side, for making the best use of 175 billion tons of low rank coal reserves, coal biosolubilization and subsequent biogasification is being projected. Consequently, beneficiated coal through biotechnology is supposed to contribute in energy mix of Pakistan for providing electricity requirements of the country and saving huge oil import bills.

  16. Malaysia as the Archetypal Garden in the British Creative Imagination

    2014-04-01

    Full Text Available European travel writing (1512–1984 represented Malaysia as a tropical Garden of Eden, an image that has also percolated into literary texts concerning the region. This article examines spatial images in British fiction through the framework of archetypal literary criticism and theories of colonial representations of space to reveal the worlding (Spivak 1999 of Malaysia as a garden. In order to ascertain the ways in which the garden archetype has been deployed by the British creative imagination in the past and the present, novels from the colonial and postcolonial periods have been selected for analysis. Three dominant incarnations of the garden archetype can be discerned throughout novels by Joseph Conrad, W. Somerset Maugham, and Anthony Burgess: the lush, Romantic garden; the restrained, ­disciplined Victorian garden; and the barren, dried-up garden. The postcolonial British novel, for its part, deploys images of the barren garden revived (William Riviere’s Borneo Fire as well as a return to the earlier Conradian image of the Romantic locus amoenus (Frederick Lees’ Fool’s Gold. This article concludes that the representation of Malaysia in various guises of the archetypal garden negates the indigenous worldview concerning space and produces instead “knowledge” about Malaysia rooted in the white man’s perspective.

  17. Caribou in British Columbia: A 1996 status report

    1998-03-01

    Full Text Available Caribou (Rangifer tarandus in British Columbia are classified into mountain, northern and boreal ecotypes based on behavioural and ecological characteristics. We recognized 12 mountain caribou herds, 27 northern caribou herds, and an area occupied by low density boreal caribou dispersed in the boreal forests of the northeast portion of the province. Abundance estimates were usually based on attempts at total counts made from the air. Trends were based on repeated population estimates or the difference between recruitment and mortality rates for each herd. In 1996 there were approximately 18 000 caribou in British Columbia; 2300 mountain and 15 600 northern and boreal. These estimates suggest a slight increase in the numbers of both ecotypes over the last 18 years. Fifteen percent of the herds were reportedly increasing, 10% were decreasing, 31% were stable, but for 44% of the herds the trend was unknown. Historically caribou were found throughout 8 of the 14 biogeoclimatic zones in B.C. Caribou are now rarely found in the Sub-Boreal Spruce zone, likely due to increased predation from wolves that increased in response to increasing moose numbers. Ranges of several herds in the Engelmann Spruce — Subalpine Fir and Alpine Tundra zones of south-eastern British Columbia are also reduced relative to historic conditions, probably because of habitat loss, habitat fragmentation, predation and hunting. Forest harvesting represents the greatest threat to caribou habitat and current research focuses on the mitigation of forest harvesting impacts.

  18. British Energy - nuclear power in the private sector

    Hawley, R. [British Energy plc, Edinburgh (United Kingdom)

    1997-04-01

    The first four months of the operation of British Energy as a privatised nuclear utility are briefly reviewed. Operational and financial performance have been good as exemplified by the figures for power output and financial return. Freedom from government control means that the options open to the company are much wider but the need to meet the expectations of shareholders is a major consideration. Added to this, the competitive nature of the electricity industry means that the cost reduction is important, though this cannot be at the expense of safety. Shareholder expectations make the funding of new nuclear power stations unrealistic at present. Increasingly, however, markets are opening up in the maintenance of existing plant and the decommissioning of older plant. The British Energy Group also has considerable expertise in the design, operation and management of power stations and of acting in a competitive energy market that could be exported. British Energy`s International Division is in place to develop this potential. (UK).

    This report was prepared in response to a request by the US Department of energy (DOE). The principal objectives of the study were to assess the current DOE coal program vis-a-vis the provisions of the Energy Policy Act of 1992 (EPACT), and to recommend the emphasis and priorities that DOE should consider in updating its strategic plan for coal. A strategic plan for research, development, demonstration, and commercialization (RDD and C) activities for coal should be based on assumptions regarding the future supply and price of competing energy sources, the demand for products manufactured from these sources, technological opportunities, and the need to control the environmental impact of waste streams. These factors change with time. Accordingly, the committee generated strategic planning scenarios for three time periods: near-term, 1995--2005; mid-term, 2006--2020; and, long-term, 2021--2040. The report is divided into the following chapters: executive summary; introduction and scope of the study; overview of US DOE programs and planning; trends and issues for future coal use; the strategic planning framework; coal preparation, coal liquid mixtures, and coal bed methane recovery; clean fuels and specialty products from coal; electric power generation; technology demonstration and commercialization; advanced research programs; conclusions and recommendations; appendices; and glossary. 174 refs.

    This report focuses mainly on developments to improve the performance of coal-based power generation technologies, which should be a priority -- particularly if carbon capture and storage takes longer to become established than currently projected. A close look is taken of the major ongoing developments in process technology, plant equipment, instrumentation and control. Coal is an important source of energy for the world, particularly for power generation. To meet the growth in demand for energy over the past decade, the contribution from coal has exceeded that of any other energy source. Additionally, coal has contributed almost half of total growth in electricity over the past decade. As a result, CO2 emissions from coal-fired power generation have increased markedly and continue to rise. More than 70% of CO2 emissions that arise from power generation are attributed to coal. To play its role in a sustainable energy future, its environmental footprint must be reduced; using coal more efficiently is an important first step. Beyond efficiency improvement, carbon capture and storage (CCS) must be deployed to make deep cuts in CO2 emissions. The need for energy and the economics of producing and supplying it to the end-user are central considerations in power plant construction and operation. Economic and regulatory conditions must be made consistent with the ambition to achieve higher efficiencies and lower emissions. In essence, clean coal technologies must be more widely deployed.

    Post, D. A.

    2013-12-01

    Mining of coal bed methane deposits (termed ';coal seam gas' in Australia) is a rapidly growing source of natural gas in Australia. Indeed, expansion of the industry is occurring so quickly that in some cases, legislation is struggling to keep up with this expansion. Perhaps because of this, community concern about the impacts of coal seam gas development is very strong. Responding to these concerns, the Australian Government has recently established an Independent Expert Scientific Committee (IESC) to provide advice to the Commonwealth and state regulators on potential water-related impacts of coal seam gas and large coal mining developments. In order to provide the underlying science to the IESC, a program of ';bioregional assessments' has been implemented. One aim of these bioregional assessments is to improve our understanding of the connectivity between the impacts of coal seam gas extraction and groundwater aquifers, as well as their connection to surface water. A bioregional assessment can be defined as a scientific analysis of the ecology, hydrology, geology and hydrogeology of a bioregion, with explicit assessment of the potential direct, indirect and cumulative impacts of coal seam gas and large coal mining development on water resources. These bioregional assessments are now being carried out across large portions of eastern Australia which are underlain by coal reserves. This presentation will provide an overview of the issues related to the impacts of coal seam gas and coal mining on water resources in Australia. The methodology of undertaking bioregional assessments will be described, and the application of this methodology to six priority bioregions in eastern Australia will be detailed. Preliminary results of the program of research to date will be assessed in light of the requirements of the IESC to provide independent advice to the Commonwealth and State governments.

  6. The new face of coal

    2007-09-15

    Coal is particularly abundant in western Canada. The expected increase in coal consumption is at variance with the worldwide demand to reduce greenhouse gas (GHG) emissions. At the current global consumption of 5 billion tonnes per year, 10 billion tonnes of carbon dioxide (CO{sub 2}) are emitted per year from coal alone. Almost none of this coal is captured and ultimately ends up in the earth's atmosphere. Much of the world's coal is used directly for electricity production. This article presented solutions to reduce the CO{sub 2} footprint of coal while expanding consumption at a rate of 74 per cent over 25 years. Nearly every coal-fired power plant in the world is becoming more efficient. Less fuel is being burned to make the same amount of energy, resulting in fewer CO{sub 2} emissions. The newest plants can be as much as 90 per cent more efficient than the oldest. In Canada, many coal-fired plants have heat rate efficiencies of 10,200 KJ/kWh, each producing 0.90 tonnes of CO{sub 2} per kWh. A potential 20 per cent reduction in CO{sub 2} emissions will result if Canada's oldest plants are replaced with best available new coal combustion technology. It is expected that within the next 30 years, almost all of Canada's aging coal-fired plants will require replacement. Interest in the coal gasification process is growing worldwide. Rather than converting coal-fired electricity production to gas, the coal can be converted to form synthesis gas that can readily be used in natural gas-fired power plants to make electricity. The coal gasification process also produces a pure stream of CO{sub 2}, which can be captured as a by-product and sequestered in the earth. CO{sub 2} sequestration is a proven technology and is currently being done with large quantities of CO{sub 2} from an operating gasification plant in North Dakota. The CO{sub 2} is being piped from North Dakota to the Weyburn oil field in Saskatchewan where it is being stored and used to

    Obtaining liquid fuels from coal which are economically competitive with those obtained from petroleum based sources is a significant challenge for the researcher as well as the chemical industry. Presently, the economics of coal liquefaction are not favorable because of relatively intense processing conditions (temperatures of 430 degrees C and pressures of 2200 psig), use of a costly catalyst, and a low quality product slate of relatively high boiling fractions. The economics could be made more favorable by achieving adequate coal conversions at less intense processing conditions and improving the product slate. A study has been carried out to examine the effect of a surfactant in reducing particle agglomeration and improving hydrodynamics in the coal liquefaction reactor to increase coal conversions...

    The author believes contaminants in our external environment play a significant role in causing cancer in humans and the cumulative impact of exposure to chemical carcinogens over a lifetime has also to be considered. An efficient method to prevent cancer is to restrict the presence of chemical carcinogens not only indoor, but also in outdoor, environments. Due to collective efforts to reduce tobacco use, lung cancer rates are falling in the USA. Most chemical carcinogens are derived from coal and petroleum, so finding substitutes for these two substances is the right way to proceed in cancer prevention efforts, the author states.

    The Eastern Kentucky coal field, along with adjacent portions of Virginia and southern West Virginia, is part of the greatest production concentration of high-heating-value, low-sulfur coal in the United States, accounting for over 27% of the 1993 U.S. production of coal of all ranks. Eastern Kentucky's production is spread among many coal beds but is particularly concentrated in a limited number of highquality coals, notably the Pond Creek coal bed and its correlatives, and the Fire Clay coal bed and its correlatives. Both coals are relatively low ash and low sulfur through the areas of the heaviest concentration of mining activity. We discuss production trends, resources, and the quality of in-place and clean coal for those and other major coals in the region. ?? 1994 Oxford University Press.

    Day, Jason

    This study examines the wind energy planning frameworks from ten North American jurisdictions, drawing important lessons that British Columbia could use to build on its current model which has been criticized for its limited scope and restriction of local government powers. This study contributes to similar studies conducted by Kimrey (2006), Longston (2006), and Eriksen (2009). This study concludes that inclusion of wind resource zones delineated through strategic environmental assessment, programme assessment, and conducting research-oriented studies could improve the current British Columbia planning framework. The framework should also strengthen its bat impact assessment practices and incorporate habitat compensation. This research also builds upon Rosenberg's (2008) wind energy planning framework typologies. I conclude that the typology utilized in Texas should be employed in British Columbia in order to facilitate utilizing wind power. The only adaptation needed is the establishment of a cross-jurisdictional review committee for project assessment to address concerns about local involvement and site-specific environmental and social concerns.

    2013-04-01

    Research with South Asian families of individuals with intellectual disabilities (ID) suggests an increased fear of stigma and isolation from the community. Evidence on attitudes towards ID among the wider community is very limited and was the focus of the present study. Responses were collected from 737 college students aged 16-19 using the Community Living Attitudes Scale-ID version. Results indicated that British South Asians (n=355) were less in favour of the social inclusion of people with ID than White British young people (n=382). British South Asian adolescents were more likely to hold the view that people with ID should be sheltered and not empowered. It is proposed that future inclusion policies integrate ethnic minority views whose religious and cultural values do not always conform to the core values of social inclusion policies. It is also proposed that culturally specific school based interventions could be introduced with the aims of decreasing stigma and fostering attitudes in line with the aims of normalisation.

    The primary objective of this research project is to develop advanced flotation methods for coal cleaning in order to achieve near total pyritic-sulfur removal at 90% Btu recovery, using coal samples procured from six major US coal seams. Concomitantly, the ash content of these coals is to be reduced to 6% or less. Work this quarter concentrated on the following: washability studies, which included particle size distribution of the washability samples, and chemical analysis of washability test samples; characterization studies of induction time measurements, correlation between yield, combustible-material recovery (CMR), and heating-value recovery (HVR), and QA/QC for standard flotation tests and coal analyses; surface modification and control including testing of surface-modifying reagents, restoration of hydrophobicity to lab-oxidized coals, pH effects on coal flotation, and depression of pyritic sulfur in which pyrite depression with calcium cyanide and pyrite depression with xanthated reagents was investigated; flotation optimization and circuitry included staged reagent addition, cleaning and scavenging, and scavenging and middling recycling. Weathering studies are also discussed. 19 figs., 28 tabs.

    Powder River Basin (PRB) coal, which accounts for over 40% of the coal consumed for power generation in the United States, was investigated for preparation of coal water slurry ( CWS). The static stability and rheology of the CWS were characterized as a function of loading. The coal loading was varied from 30% to 50% and both ionic ( sodium polystyrene sulphonate (PSS)) and nonionic (Triton X-100) surfactants were employed as additives. The addition of PSS to PRB slurries was found to yield poor static stability. On the other hand, Triton X-100 was found to be an effective surfactant, reducing the sedimentation by more than 50% compared to the one without surfactant in 45% CWS. Adding Triton X-100 reduces the viscosity of the CWS for coal loadings of 30% and 40% . Although the viscosities for coal loading of 42. 5% and 45% are higher when Triton X-100 is added, the static stability is significantly better than for samples without surfactant. The highest coal loading for PRB slurry with acceptable viscosity for pumping is 42. 5% .

    1992-05-15

    The formation and retention of methane in coalbeds was studied for ten Utah coal samples, one Colorado coal sample and eight coal samples from the Argonne Premium Coal Sample Bank.Methane gas content of the Utah and Colorado coals varied from zero to 9 cm{sup 3}/g. The Utah coals were all high volatile bituminous coals. The Colorado coal was a gassy medium volatile bituminous coal. The Argonne coals cover a range or rank from lignite to low volatile bituminous coal and were used to determine the effect of rank in laboratory studies. The methane content of six selected Utah coal seams and the Colorado coal seam was measured in situ using a special sample collection device and a bubble desorbometer. Coal samples were collected at each measurement site for laboratory analysis. The cleat and joint system was evaluated for the coal and surrounding rocks and geological conditions were noted. Permeability measurements were performed on selected samples and all samples were analyzed for proximate and ultimate analysis, petrographic analysis, {sup 13}C NMR dipolar-dephasing spectroscopy, and density analysis. The observed methane adsorption behavior was correlated with the chemical structure and physical properties of the coals.

    Vanadium in coals may have potential environmental and economic impacts. However, comprehensive knowledge of the geochemistry of V in coals is lacking. In this study, abundances, distribution and modes of occurrence of V are reviewed by compiling >2900 reported Chinese coal samples. With coal reserves in individual provinces as the weighting factors, V in Chinese coals is estimated to have an average abundance of 35.81 μg/g. Large variation of V concentration is observed in Chinese coals of different regions, coal-forming periods, and maturation ranks. According to the concentration coefficient of V in coals from individual provinces, three regions are divided across Chinese coal deposits. Vanadium in Chinese coals is probably influenced by sediment source and sedimentary environment, supplemented by late-stage hydrothermal fluids. Specifically, hydrothermal fluids have relatively more significant effect on the enrichment of V in local coal seams. Vanadium in coals is commonly associated with aluminosilicate minerals and organic matter, and the modes of V occurrence in coal depend on coal-forming environment and coal rank. The Chinese V emission inventory during coal combustion is estimated to be 4906 mt in 2014, accounting for 50.55 % of global emission. Vanadium emissions by electric power plants are the largest contributor.

    Full Text Available The enrichment of coalbed methane (CBM and the outburst of gas in a coal mine are closely related to the nanopore structure of coal. The evolutionary characteristics of 12 coal nanopore structures under different natural deformational mechanisms (brittle and ductile deformation are studied using a scanning electron microscope (SEM and low-temperature nitrogen adsorption. The results indicate that there are mainly submicropores (2~5 nm and supermicropores (4 m2/g, with pore sizes <5 nm in ductile deformed coal. The nanopore structure (<100 nm and its distribution could be affected by macromolecular structure in two ways. Interconversion will occur among the different size nanopores especially in ductile deformed coal.

    Power plants in China have to burn blended coal instead of one specific coal for a variety of reasons. So it is of great necessity to investigate the combustion of blended coals. Using a test rig with a capacity of 640 MJ/h with an absolute milling system and flue gas online analysis system, characteristics such as burnout, slag, and pollution of some blended coals were investigated. The ratio of coke and slag as a method of distinguishing coal slagging characteristic was introduced. The results show that the blending of coal has some effect on NOx but there is no obvious rule. SOx emission can be reduced by blending low sulfur coal.

    1992-03-29

    In order to convert lignite coals into liquid fuels, gases or chemical feedstock, the macromolecular structure of the coal must be broken down into low molecular weight fractions prior to further modification. Our research focused on this aspect of coal bioprocessing. We isolated, characterized and studied the lignite coal-depolymerizing organisms Streptomyces viridosporus T7A, Pseudomonas sp. DLC-62, unidentified bacterial strain DLC-BB2 and Gram-positive Bacillus megaterium strain DLC-21. In this research we showed that these bacteria are able to solubilize and depolymerize lignite coals using a combination of biological mechanisms including the excretion of coal solublizing basic chemical metabolites and extracellular coal depolymerizing enzymes.

    The initial goal of the research project was to develop methods of coal surface control in advanced froth flotation to achieve 90% pyritic sulfur rejection, while operating at Btu recoveries above 90% based on run-of-mine quality coal. Moreover, the technology is to concomitantly reduce the ash content significantly (to six percent or less) to provide a high-quality fuel to the boiler (ash removal also increases Btu content, which in turn decreases a coal's emission potential in terms of lbs SO{sub 2}/million Btu).

    The Appalachian Clean Coal Technology Consortium (ACCTC) has been established to help U.S. coal producers, particularly those in the Appalachian region, increase the production of lower-sulfur coal. The cooperative research conducted as part of the consortium activities will help utilities meet the emissions standards established by the 1990 Clean Air Act Amendments, enhance the competitiveness of U.S. coals in the world market, create jobs in economically-depressed coal producing regions, and reduce U.S. dependence on foreign energy supplies. The research activities will be conducted in cooperation with coal companies, equipment manufacturers, and A&E firms working in the Appalachian coal fields. This approach is consistent with President Clinton`s initiative in establishing Regional Technology Alliances to meet regional needs through technology development in cooperation with industry. The consortium activities are complementary to the High-Efficiency Preparation program of the Pittsburgh Energy Technology Center, but are broader in scope as they are inclusive of technology developments for both near-term and long-term applications, technology transfer, and training a highly-skilled work force.

    Full Text Available Availability of, and access to, coal is a crucial element of modern economies and it helps pave the way for human development. Accordingly, the thermal power sector and steel industries have been given a high priority in the national planning processes in India and a concerted focus on enhancing these sectors have resulted in significant gain in generation and availability of electricity and steel in the years since independence. To meet the need of huge demand of power coal is excavated. The process of excavation to the use of coal is potential enough to degrade the environment. Coal Mining is a development activity, which is bound to damage the natural ecosystem by all its activities directly and ancillary, starting from land acquisition to coal beneficiation and use of the products. Huge areas in the Raniganj and Jharia coal field in India have become derelict due to abandoned and active opencast and underground mines. The study is pursued to illustrate the facts which show the urgent need to clean coal mining in India.

    1992-05-07

    In this report, we present an improved, feasible and potentially cost effective method of cleaning and beneficiating ultrafine coal. Increased mechanization of mining methods and the need towards depyritization, and demineralization have led to an increase in the quantity of coal fines generated in recent times. For example, the amount of {minus}100 mesh coal occurring in coal preparation plant feeds now typically varies from 5 to 25% of the total feed. Environmental constraints coupled with the greatly increased cost of coal have made it increasingly important to recover more of these fines. Our method chemically modifies the surface of such coals by a series of gaseous phase treatments employing Friedel-Crafts reactions. By using olefins (ethene, propene and butene) and hydrogen chloride catalyst at elevated temperature, the surface hydrophobicity of coal is enhanced. This increased hydrophobicity is manifest in surface phenomena which reflect conditions at the solid/liquid interphase (zeta potential) and those which reflect conditions at the solid/liquid/gas interphases (contact angle, wettability and floatability).

The railways' monopoly on transporting coal and its poor capability to do so are the two main reasons for the high cost of coal. Foreign investment is nos seen as having prompted improvements in China's ports and its coal mining sector; China is promoting development of a large coal-to-liquids industry.

    By testing the temperature of the coal and the stress of the working surface,we got the variation law of coal temperature and coal stress during the excavation.The result shows that the activities of mining affect the coal temperature,the fluctuation of coal temperature and the coal stress is synchronous.During the smooth change of crustal stress,the coal temperature basically keeps unchanged,when the dynamic phenomenon appears,the coal temperature changes,as well the coal stress.Therefore,we can use the online coal temperature monitoring system to test the coal temperature of the working surface continuously,and it can provide basic information for forecasting coal mine power disaster before it happens.

    2011-12-15

    The coal sector in Kazakhstan is said to have enough reserves to last over 100 years, but the forecasted reserves are expected to last several hundreds of years. This makes investing in the fuel and energy sector of the country an attractive option for many international and private organisations. The proven on-shore reserves will ensure extraction for over 30 years for oil and 75 years for gas. The future development of the domestic oil sector depends mainly on developing the Kazakh sector of the Caspian Sea. The coal sector, while not a top priority for the Kazakh government, puts the country among the world's top ten coal-rich countries. Kazakhstan contains Central Asia's largest recoverable coal reserves. In future, the development of the raw materials base will be achieved through enriching and improving the quality of the coal and the deep processing of coal to obtain fluid fuel and synthetic substances. Developing shale is also topical. The high concentration of methane in coal layers makes it possible to extract it and utilise it on a large scale. However, today the country's energy sector, which was largely established in the Soviet times, has reached its potential. Kazakhstan has about 18 GW of installed electricity capacity, of which about 80% is coal fired, most of it built before 1990. Being alert to the impending problems, the government is planning to undertake large-scale modernisation of the existing facilities and construct new ones during 2015-30. The project to modernise the national electricity grid aims to upgrade the power substations to ensure energy efficiency and security of operation. The project will result in installation of modern high-voltage equipment, automation and relay protection facilities, a dispatch control system, monitoring and data processing and energy management systems, automated electricity metering system, as well as a digital corporate telecommunication network.

    2010-02-15

    Vietnam's energy economy is largely served by traditional biofuels and oil products. Within the power generating sector, hydropower and gas-fired power dominate. However, Vietnam still maintains a 40 Mt/y coal industry, parts of which have recently undergone a long overdue programme of renovation and expansion. Vietnam has been a successful exporter of anthracite, with more than half of the country's production being shipped or barged to steel mills in Japan or power stations in southern China, as well as most other Far Eastern coal importers. The industry is due to take a different form. Opencast mining has recently accounted for around 60% of production but this mining method could be phased out as reserves become more difficult and costly to extract. A shift to underground mining is expected, with a greater emphasis on more modern and mechanised production techniques. Coal is located mainly in the coalfields in Quang Ninh in the north easternmost province of Vietnam. The lower rank reserves located within the Red River coalfields, close to the existing anthracite operations, may yield many more millions of tonnes of coal for exploitation. Underground coal gasification could possibly be exploited in the deeper reserves of the Red River Basin. While coal production could rapidly change in future years, the power generation sector is also transforming with the country's 12,000 MWe development programme for new coal-fired power capacity. The economy suffers from a threat of power shortages due to a lack of generating and transmission capacity, while inefficiencies blight both energy production and end-users. Delivering power to the regions of growth remains difficult as the economy and the demand for power outpaces power generation. While hydroelectric power is being pursued, coal is therefore becoming a growing factor in the future prosperity of the Vietnamese economy. 111 refs., 33 figs., 11 tabs.

    Ocean Networks Canada (ONC), a not-for-profit initiative by the University of Victoria that operates several cabled ocean observatories, is developing a new generation of ocean observing systems (referred to as Smart Ocean Systems™), involving advanced undersea observation technologies, data networks and analytics. The ONC Tsunami project is a Smart Ocean Systems™ project that addresses the need for a near-field tsunami detection system for the coastal areas of British Columbia. Recent studies indicate that there is a 40-80% probability over the next 50 for a significant tsunami impacting the British Columbia (BC) coast with runups higher than 1.5 m. The NEPTUNE cabled ocean observatory, operated by ONC off of the west coast of British Columbia, could be used to detect near-field tsunami events with existing instrumentation, including seismometers and bottom pressure recorders. As part of this project, new tsunami simulations are underway for the BC coast. Tsunami propagation is being simulated with the FUNWAVE-TVD model, for a suite of new source models representing Cascadia megathrust rupture scenarios. Simulations are performed by one-way coupling in a series of nested model grids (from the source to the BC coast), whose bathymetry was developed based on digital elevation maps (DEMs) of the area, to estimate both tsunami arrival time and coastal runup/inundation for different locations. Besides inundation, maps of additional parameters such as maximum current are being developed, that will aid in tsunami hazard assessment and risk mitigation, as well as developing evacuation plans. We will present initial results of this work for the Port Alberni inlet, in particular Ucluelet, based on new source models developed using the best available data. We will also present a model validation using measurements of the 2011 transpacific Tohoku-oki tsunami recorded in coastal BC by several instruments from various US and Canadian agencies.

    1999-01-01

    Through site observation and indoor measurements in XieJiaji No.2 Coal Mine in Huainen and Luling Coal Mine in Huaibei, it is discovered that the fragmentation degree are different in different coal seams in same mining district and even in sublevels of the same coal seam, the coal mass structures exist much difference. By analyzing the relationship between the constitution of coal matters and the epigenesis breakage of coal. This paper points out that the internal factor which causes the diversity of the coal mass structure comes from the diversity in the contents of telocollinite and desmocollinite in the vitrinite. The contenet of desmocollinite is higher than that of telocollinite in intact coal seam (sublevel) but the former is less than the later in breaking sublevel, the diversity of constituent content more affects the epigenetic fragmentation degree of coal seam. The content of desrnocollinite proves lower than that of telocollinite in the broken coal seam. The new understanding has directing, and reference for the study of coal petrology, coal mine gas geology and coal methane.

    The aim of this research project is to develop a methodology to predict, from a knowledge of feed and catalyst properties, effectiveness factors for catalytic hydroprocessing of coal and coal liquids. To achieve this aim, it is necessary to account for restrictive diffusion, which has not hitherto been done from a fundamental approach under reaction conditions. The research proposed here entails a study of hydrodenitrogenation of model compounds and coal-derived liquids using three NiMo/alumina catalysts of different pore size to develop, for restrictive diffusion, a relationship that can be used for estimating reliable effectiveness factors. The program is divided into four parts: measurements of pertinent properties of the catalysts and of a coal liquid and its derived boiling-point cuts; determination of effective diffusivities and tortuosities of the catalysts; development of restrictive diffusion correlations from data on model N-compounds at reaction conditions; and testing of correlations with coal-liquid cuts and whole coal-liquid feed, modifying correlations as necessary.

    to the standard method of Kohlbeck and Scheidegger. If the bisectrices
    of the preferred joint orientations are interpreted as principal directions
    of the neotectonic stress field, the maximum compression in the latter
    is found to be from NE-SW (in the South to NNE-SSW (in the North.
    This agrees well with data regarding the neotectonic intraplate stresses

    Despite social inequality in health being well documented, it is still debated which causal mechanism best explains the negative association between socioeconomic position (SEP) and health. This paper is concerned with testing the explanatory power of three widely proposed causal explanations...... of the British Household Panel Survey. Household income and location on the Cambridge Scale is included as measures of different dimensions of SEP and health is measured as a latent factor score. The causal hypotheses are tested using a time-based Granger approach by estimating dynamic fixed effects panel...

    1986-11-01

    A brief history is given of research in Czechoslovakia, which took 3 main factors into account: environmental protection, geological situation and need to produce gas for use both within the plant and elsewhere. In order to assess economic viability, model studies were performed on following mines: Podlesice (North Bohemia), Vatovce (South Slovakia), Syrenov (East Moravia), Zukovsky Hrbet (Ostrava-Karvina), Stonovska (Ostrava-Karvina) and Merkur (North Bohemia). Figures given in tabular form show that underground gasification at these sites would be cheaper than importing natural gas. Problems are discussed associated with underground gasification and it is concluded that research must be conducted into drilling techniques, drill design, methods of cutting through coal seam between shafts, underground generator design, methods of gasifying several seams with one shaft and methods of dealing with residual pillars.

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

  10. Progress in Coal Liquefaction Technologies

    2006-01-01

    Worldwide primary energy consumption is entering an era of pluralism and high quality under the influence of rapid economic development, increasing energy shortage and strict environmental policies. Although renewable energy technology is developing rapidly, fossil fuels (coal, oil and gas) are still the dominant energy sources in the world. As a country rich in coal but short ofoil and gas, China's oil imports have soared in the past few years. Government, research organizations and enterprises in China are paying more and more attention to the processes of converting coal into clean liquid fuels. Direct and indirect coal liquefaction technologies are compared in this paper based on China's current energy status and technological progress not only in China itself but also in the world.

    Energy Technology Data Exchange (ETDEWEB)

    1992-01-01

    Culture screening and performance studies were performed with a variety of cultures in removing nitrogen compounds from coal liquid. Two cultures were shown to be effective in removing 17 and 26 percent of the nitrogen in coal liquid as determined by elemental analysis. Experiments will continue in an effort to find additional cultures and isolates able to degrade nitrogen, as well as oxygen and sulfur as heteroatom compounds, from coal liquids. A biological process for upgrading of coal liquids would offer significant advantages, such as operation at ordinary temperature and pressure with better energy efficiency. Of greater importance is the fact that microorganisms do not require an external supply of hydrogen for heteroatom removal, obtaining required hydrogen from water. Furthermore, the biocatalysts are continuously regenerated by growth on the heteroatom compounds. Ring structures are degraded as the heteroatoms are removed. The heteroatoms are in an inocuous form, such as NH[sub 3], SO[sub 4][sup 2[minus

  14. Coal Beneficiation by Gas Agglomeration

    2000-03-15

    Coal beneficiation is achieved by suspending coal fines in a colloidal suspension of microscopic gas bubbles in water under atmospheric conditions to form small agglomerates of the fines adhered by the gas bubbles. The agglomerates are separated, recovered and resuspended in water. Thereafter, the pressure on the suspension is increased above atmospheric to deagglomerate, since the gas bubbles are then re-dissolved in the water. During the deagglomeration step, the mineral matter is dispersed, and when the pressure is released, the coal portion of the deagglomerated gas-saturated water mixture reagglomerates, with the small bubbles now coming out of the solution. The reagglomerate can then be separated to provide purified coal fines without the mineral matter.

    A Clean Coal Diesel project was undertaken to demonstrate a new Clean Coal Technology that offers technical, economic and environmental advantages over conventional power generating methods. This innovative technology (developed to the prototype stage in an earlier DOE project completed in 1992) enables utilization of pre-processed clean coal fuel in large-bore, medium-speed, diesel engines. The diesel engines are conventional modern engines in many respects, except they are specially fitted with hardened parts to be compatible with the traces of abrasive ash in the coal-slurry fuel. Industrial and Municipal power generating applications in the 10 to 100 megawatt size range are the target applications. There are hundreds of such reciprocating engine power-plants operating throughout the world today on natural gas and/or heavy fuel oil.

    The objective of this project is to move toward the development of a predictive capability with quantified uncertainty bounds for pilot-scale, single-burner, oxy-coal operation. This validation research brings together multi-scale experimental measurements and computer simulations. The combination of simulation development and validation experiments is designed to lead to predictive tools for the performance of existing air fired pulverized coal boilers that have been retrofitted to various oxy-firing configurations. In addition, this report also describes novel research results related to oxy-combustion in circulating fluidized beds. For pulverized coal combustion configurations, particular attention is focused on the effect of oxy-firing on ignition and coal-flame stability, and on the subsequent partitioning mechanisms of the ash aerosol.

    The recent progress of non-covalent associative structure of coal, and the mechanisms of the CS2/NMP (1:1 by volume) mixed solvent and the additive addition enhancing the extraction yield of coals were reviewed, and the aggregation behavior of coal in solid and solution states were presented, and the aggregation behavior of coal in solid and solution states were introduced in this paper. Coal extraction and swelling in organic solvents at room temperature were the most useful methods to understand the associative structure of coal. CS2/NMP (1:1 by volume) is a unique solvent to give high extraction yields for some bituminous coals. Some additives can dissociate the stronger interactions among coal molecules and enhance the extraction yields of coal in the mixed solvent.

    The paper discusses Ukraine's coal mining industry. Ukraine has the 8th place in the world's coal reserves and 10th by volume of production. The industry has declined in recent years - production fell from 135.6 million tons in 1991 to 80.151 million tons in 2004. The Donetsk coal basin is the main producer of Ukraine's power station coal, coking coal and anthracite, mostly of high sulphur content. Coal exports in 2004 amounted to 420 thousand tons. Coal is imported mainly from Russia and Kazakhistan. Ukraine has 13 by-product coke plants, utilizing damp coke quenching technology. The article gives figures for coal transshipment of coal and coke through its ports in 2004. The text of the presentation is accompanied by a file of 34 slides/overviews. 13 figs., 2 tabs.

    Polish bituminous coal basins are associated exclusively with Carboniferous deposits, differing in origin and geological structure. This paper presents only short review of papers of Polish authors on coal facies studies of Carboniferous coals occurring in the Lower Silesian Coal Basin (LSCB), Upper Silesian Coal Basin (USCB) and Lublin Coal Basin (LCB) of Poland. Facies investigations of Carboniferous coals of Poland have been in progress over 20 years. The results of these studies have provided new information on such subjects as: (1) recognition of main depositional conditions in paleomires, (2) determine prevailing paleoplant communities, (3) appraisal of peat-forming environment reconstruction-types and characteristics of paleomires. These facies analyses are connected to results of such studies as: pure coal petrology, using maceral and microlithotype composition as parameters of the environment of coal deposition, combined results of petrological, palynological and sedimentological studies.

    Coal of Jurassic age occurs onshore Denmark and in the Danish North Sea, whereas coal of Carboniferous and Miocene age only occurs in the Danish North Sea and onshore Denmark, respectively. The Lower-Middle Jurassic coals are the most widespread and best documented. Onshore Denmark the coals are of low rank while the Jurassic coals in the North Sea are thermally mature and hydrocarbon generating in the Soegne Basin. The Jurassic coals have a maximum thickness of similar2 m and were formed in coastal plain mires and in inland fresh water mires. The Miocene brown coals, up to similar2 m thick, were formed in an overall deltaic setting. Lower Carboniferous and Palaeogene coals occur in northern Greenland, Middle Jurassic coals in northeast Greenland, and Cretaceous coals in western Greenland. The Middle Jurassic low rank coals have been investigated in detail. The up to similar3.5-m-thick coal seams accumulated in coastal mires and they may have an extraordinary resinite-enriched composition. Only a single Cretaceous coal seam has been investigated with regard to the depositional environment; the seam records drowning of a peat mire. The Lower Carboniferous and Palaeogene coals have not been investigated.

    Coal is the biggest single source of energy for electricity production and its share is growing. The efficiency of converting coal into electricity matters: more efficient power plants use less fuel and emit less climate-damaging carbon dioxide. This book explores how efficiency is measured and reported at coal-fired power plants. With many different methods used to express efficiency performance, it is often difficult to compare plants, even before accounting for any fixed constraints such as coal quality and cooling-water temperature. Practical guidelines are presented that allow the efficiency and emissions of any plant to be reported on a common basis and compared against best practice. A global database of plant performance is proposed that would allow under-performing plants to be identified for improvement. Armed with this information, policy makers would be in a better position to monitor and, if necessary, regulate how coal is used for power generation. The tools and techniques described will be of value to anyone with an interest in the more sustainable use of coal.

    Novel chemicals that can be used for increasing the efficiency of fine coal dewatering was developed at Virginia Tech. During the past quarter, Reagent A was tested on three different coal samples in laboratory vacuum filtration tests. these included flotation products from Middle Fork plant, Elkview Mining Company, and CONSOL, Inc. the tests conducted with the Middle Fork coal sample (100 mesh x 0) showed that cake moisture can be reduced by more than 10% beyond what can be achieved without using dewatering aid. This improvement was achieved at 1 lb/ton of Reagent A and 0.1 inch cake thickness. At 0. 5 inches of cake thickness, this improvement was limited to 8% at the same reagent dosage. the results obtained with the Elkview coal (28 mesh x 0) showed similar advantages in using the novel dewatering aid. Depending on the reagent dosage, cake thickness, drying cycle time and temperature, it was possible to reduce the cake moisture to 12 to 14% rage. In addition to achieving lower cake moisture, the use of Reagent A substantially decreased the cake formation time, indicating that the reagent improves the kinetics of dewatering, The test results obtained with CONSOL coal were not as good as with the other coals tested in the present work, which may be attributed to possible oxidation and/or contamination.

  5. Geological classification of coal deposits

    Bretsnaidr, P.

    1985-02-01

    A new classification of coal deposits developed by the author is evaluated. The classification considers only selected factors which characterize a coal deposit. Each factor is described by a number of points ranging from 0 to 10. Geologic structure (deposits with one or more seams or with seam groups) is described using from 1 to 10 points. Secondary deformation of a coal deposit (e.g. tectonics) and hydrogeology (aquifers, filtration properties, etc.) are described using a 10 point scale. Coal seam structure (with or without partings) is characterized using 1 to 5 points. Coal seam thickness and its stability (4 thickness classes from 0.4 to 1.0 m, 1 to 3 m, 3 to 10 m and above 10 m) is described using 0 to 5 points. Coal seam quality (ash content, calorific value and coking properties) is described using 0 to 5 points. Other factors are characterized using a 10 point scale. Use of this deposit classification is explained using four examples: the Merkur surface mine (uncomplicated conditions), the Nosek surface mine (relatively complicated conditions), the Slany deposit (with complicated conditions) and the Jan Sverma deposit (with extremely complicated conditions).

  6. Norms of care in British and American neurologic practice.

    1988-01-01

    At a Consensus Development Conference on the Scope of Neurological Practice in the United Kingdom, 26 British specialists in the field of neurology constructed norms of care for patients with 11 neurologic disorders. For each disorder, these specialists specified the percentage of all patients who should see a physician, as well as the percentage who should see a consultant neurologist, the appropriate duration of the initial patient encounter, and the appropriate frequency of follow-up visits per annum. When compared with American estimates used in health manpower planning, British neurologists generally make a far greater allowance for patient self-care, as well as care by nonphysician health care providers, allow less time for patient encounters, and see a need for follow-up care less frequently. These marked differences in the perceptions of specialists of a normative character may determine, in part, the different "practice styles" of physicians in different regions that cannot be explained in economic terms. Results suggest that the practice style concept should be broadened to include the use of health personnel of many types, the scope of specialty medicine, and the role definition of primary care.

    Full Text Available Polyploidization plays an important role in species formation as chromosome doubling results in strong reproductive isolation between derivative and parental taxa. In this note I describe a new species, Mimulus peregrinus (Phrymaceae, which represents the first recorded instance of a new British polyploid species of Mimulus (2n = 6x = 92 that has arisen since the introduction of this genus into the United Kingdom in the 1800’s. M. peregrinus presents floral and vegetative characteristics intermediate between M. guttatus and M. luteus, but can be distinguished from all naturalized British Mimulus species and hybrids based on a combination of reproductive and vegetative traits. M. peregrinus displays high pollen and seed fertility as well as traits usually associated with genome doubling such as increased pollen and stomata size. The intermediate characteristics of M. peregrinus between M. guttatus (2n = 2x = 28 and M. luteus (2n = 4x = 60-62, and its close affinity with the highly sterile, triploid (2n = 3x = 44-45 hybrid taxon M. × robertsii (M. guttatus × M. luteus, suggests that M. peregrinus may constitute an example of recent allopolyploid speciation.

  9. Where are we now in British health economics?

    Science.gov (United States)

    Blaug, M

    1998-08-01

    Health economics took off in 1970 or thereabouts, just after the take-off date for the economics of education. Although early health economics made use of human capital theory as did the economics of education, it soon took a different route inspired by Arrow's work on medical insurance. The economics of education failed to live up to its promising start in the 1960s and gradually ran out of steam. The economics of health, however, has made steady theoretical and empirical progress since 1970, principally in coming to grips with the implications of supplier-induced demand and the difficulties of evaluating health care outcomes. Some of the best work on British health economics has been in the area of normative welfare economics, defining more precisely what is meant by equity in the delivery of health care and measuring the degree of success in achieving equity. Recent efforts to reform the NHS by the introduction of 'quasi markets' have improved the quantity and quality of health care in Britain. In short, British health economics has been characterised by the use of Pigovian piecemeal rather than Paretian global welfare economics, retaining a distinctive style that sets it apart from American health economics.

  10. Subtitle Translation of Humour in British TV Sitcoms

    2014-01-01

    This thesis explores the translation of three categories of British humour-universal, cultural and linguistic humour in the light of GTVH(General Theory of Verbal Humour) and Relevance Theory. GTVH benefits the study of humour translation by providing an analytical framework of six Knowledge Resources which include Language (LA), Narrative Strategy(NS), Target (TA), Situation(SI), Logical Mechanism(LM) and Script Opposition (SO). The hierarchy of Knowledge Resources is used to make an analysis of the internal structure of humour and Relevance theory functions as a translation theory to check whether the translation is appropriate to achieve optimal relevance. Taking the translation examples from British TV sitcoms“Yes, Prime Minis-ter”and“Little Britain”,the thesis probes into the most important Knowledge Resources in these three kinds of humour respec-tively, analyzes the loss and gain of humour reproduction in fansubbers’translation and makes a few adjustments to some inappro-priate translation versions to“achieve the maximization of relevance”.

    A. L. Berridge

    2015-05-01

    Full Text Available The Crimean War revealed in this issue of '19' is of such rich and varied historical interest as to make a mystery of its relative obscurity with the general public in the UK. My own article adopts a novelist’s perspective to chart some aspects of this popular decline, exploring the treatment of the Siege of Sebastopol through the media of painting, literature, and cinema, and considering whether those aspects of the war that have made the greatest impression on the public mind are also those that make it least commercially attractive. It also examines the more official legacy, from the treatment of war dead to the changing face of sculpted memorials, and by comparing British commemoration with that of Russians in Crimea, discusses the possible role played in national memory by both shame and pride. In a final brief analysis of the 1968 film 'The Charge of the Light Brigade', I consider the extent to which modern rejection of Victorian values has created historical distortion, and whether a more truthful presentation might better serve the cause of preserving an important war in the British public consciousness.

  12. The French Army and British Army Crimean War Reforms

    Directory of Open Access Journals (Sweden)

    Anthony Dawson

    2015-05-01

    Full Text Available French army logistics of the Crimean War are generally considered to have been better organized than their British counterpart. This sometimes erroneous belief was fuelled by letters home (from officers and men as well as by the reporting of various ‘special correspondents’ in the Crimea, and created an emotional response favourable to the ordinary soldier and, in particular, towards the French. This then became the basis for arguments for reform of the British army in the military and domestic press and in Parliament. Clamour for reform on French lines led to official studies being made of the French army, especially of logistics, officer education, and even uniforms. The French army, however, was little understood and the resulting ephemeral corps-style units (such as Land Transport Corps, Army Work Corps, and Mounted Staff Corps were quickly found faulty. In fact, official study of the French army often had little or no effect on the major reforms of the war. Emulation of the French was ultimately short-lived and of little effect; the favourable perception of the French was based on short-term emotional response and, indeed, the desire for army reform had its sting drawn with the establishment of the Roebuck Committee. Post-war retrenchment and success in the Indian Mutiny would stifle what was left of the reform debate.

  13. The Role of Capital Productivity in British Airways' Financial Recovery

    Science.gov (United States)

    Morrell, Peter

    1999-01-01

    British Airways (BA) was privatised in 1987, but its financial recovery occurred a number of years earlier. This recovery was sustained throughout the early 1990s economic recession, a period when few major airlines were operating profitably. This paper examines the role of productivity developments at British Airways from the early 1980s through 1996. The emphasis is on capital productivity and investment, but changes in capital intensity and labour productivity are also evaluated. Various measures are considered for both capital and labour productivity: outputs are measured in available tonne-kms (ATKS) and revenue tonne-kms (RTKs), with the former preferred over the latter two measures, after adjustment for work performed by BA for others. Capital inputs are measured in equivalent lease costs adjusted to constant prices with a different treatment of flight and ground equipment or assets. Labour inputs are derived from total payroll costs deflated by a UK wage price index. The airline made considerable capital investments over the period and at the same time went through two major processes of labour restructuring. This resulted in a gradual increase in capital intensity, relative high labour productivity growth, but poor capital productivity performance. However, capital investment played an important role in the airline's sustained labour and total factor productivity over the whole period.

  14. The Role of the British Crown on Security Issues

    Directory of Open Access Journals (Sweden)

    Behar Selimi

    2016-07-01

    Full Text Available United Kingdom is a limited parliamentary monarchy, in which state sovereignty is exercised jointly by two basic political institutions: Royal Crown and Parliament. The credit for a successful political co-governance of these institutions, which are simultaneously bearers of popular sovereignty, are usually addressed to the Queen's lack of executive power to exercise power alone and hence all the restraint in the race for primate of governance. It goes even further considering that the Queen is quite weak and has only ceremonial functions, which do not disturb the Parliament. However, a careful researcher may notice that the Queen continues to affect the British Government in general and in particular on defence issues. Declassification of communication between Prince Charles and the Government in 2013, pointed out a continuing impact of the Queen and her son on many political issues, including those of defence and security. Since Britain has no codified constitution in a single document, it is not easy to determine the real power and competences of the Queen. It is even more difficult, because customary law and precedent prevail. Therefore, the real definition of the role of the Queen in general in the British Government, can be done by studying the culture, structure and constitutional practice. On their basis I will try to determine the real impact of the Queen in matters of defence and security, whether through her prerogatives in relation to the Government and Parliament, or through moral and informal influence in relation to the Prime Minister and particular ministers.

    2014-02-01

    The problematic use of mobile phones among adolescents has not been widely studied. There are very few instruments for assessing potential technological addiction to mobile phones, or for categorizing different types of users or uses. The most widely used scale is the Mobile Phone Problem Use Scale (MPPUS), which is used to study adult populations, and has been applied in various forms in international contexts. The aims of this study were to adapt the Spanish version of this scale (MPPUSA) to British adolescents, and then to estimate the prevalence of possible problematic users. A questionnaire was administered to a sample of 1,529 secondary school pupils aged between 11 and 18 years, with 1,026 completed questionnaires being collected. The analysis showed that the factor and construct validity and reliability were comparable to those obtained in previous studies. The prevalence of problematic users among the students was 10%, and the typical problematic user tended to be an adolescent between 11 and 14 years old, studying in a public school, who considered themselves to be an expert user of this technology, who made extensive use of his/her mobile phone, and who attributed the same problem of use among their peers.

    Full Text Available The rapid industrialization and growing energy needs have put a great stress on the conventional energy resources. This is even more concerning for a country like India which is a net importer of oil. To meet the ever increasing need for energy, it is essential that the search for unconventional energy is intensified. This paper deals with the estimation of coal bed methane potential of the Margherita Coal Field of Assam, India. For this purpose, eight coal samples were collected from Tirap O.C.P., Ledo UG Incline and Tikak O.C.P collieries of the Margherita coal field. Proximate analysis, megascopic study and finally qualitative analysis of these eight samples was undertaken. After analysis, the inferred reserves of CBM at Margherita Coalfield, was found to be in the range of 42.5-49.04 Billion Cubic Meter.

  17. Relationship Between Coal Powder and Its Combustibility

    Coal's volatile component,ash and fixed carbon content have different functions in different stages of a combustion process, but the traditional coal classification can precisely show its combustion property.In this experiment coal's evaluation indexes (ignition index Di),(burn off index Df) were used to qualitatively show the ignition property and combustion ending property of coal samples.Meanwhile,considering actual heating circumstances in calciner (in cement plants),this thesis established the relationship among the ignition index,burn off index and coal's industrial analysis value, which makes it possible for the user to predict the quality of coal before using it and is very valuable in practice.

    The focus of this research is on coal quality enhancement, which includes reduction in the sulfur content and increase in heating value through simple, innovative, and commercially viable coal cleaning strategies. These strategies involve fine coal cleaning, plant optimization, partial coarse coal liberation, and multiple product generation. Evaluations on five mines in Illinois have indicated a potential to reduce the sulfur dioxide emission potential of these coals by up to 20%, while increasing the product heating value by up to 250 kcal/kg (450 BTU/lb). In addition, increases in coal yield by 2-6% are predicted depending on the specific conditions at the evaluated mine.

    Full Text Available Notwithstanding the absence of bulldogs, Britfest with its re-creation and representation of Britishness provides an entry point for investigating the complex meanings within the transitional narratives of migrancy, ethnicity and ‘belonging’ among British migrants in modern Australia. The identification and promotion of Britishness at this event reflects recent trends in the re-imagining of that Britishness, which has also become the focus of popular and scholarly debate. In much of this debate, events such as Britfest are seen as representative of a newly emergent sense of identity among British migrants—as an organic reawakening of community pride, nationhood and sense of (an often privileged place in Australia.

  19. Drivers for the renaissance of coal.

    Science.gov (United States)

    Steckel, Jan Christoph; Edenhofer, Ottmar; Jakob, Michael

    2015-07-21

    Coal was central to the industrial revolution, but in the 20th century it increasingly was superseded by oil and gas. However, in recent years coal again has become the predominant source of global carbon emissions. We show that this trend of rapidly increasing coal-based emissions is not restricted to a few individual countries such as China. Rather, we are witnessing a global renaissance of coal majorly driven by poor, fast-growing countries that increasingly rely on coal to satisfy their growing energy demand. The low price of coal relative to gas and oil has played an important role in accelerating coal consumption since the end of the 1990s. In this article, we show that in the increasingly integrated global coal market the availability of a domestic coal resource does not have a statistically significant impact on the use of coal and related emissions. These findings have important implications for climate change mitigation: If future economic growth of poor countries is fueled mainly by coal, ambitious mitigation targets very likely will become infeasible. Building new coal power plant capacities will lead to lock-in effects for the next few decades. If that lock-in is to be avoided, international climate policy must find ways to offer viable alternatives to coal for developing countries.

  20. Short description of the Peruvian coal basins

    2004-04-23

    This work synthesizes the main general characteristics of the Peruvian Coal Basins in relation to age, coal facies and coal rank. Peruvian coals are located in a series of coal basins from the Paleozoic to the Cenozoic age. Paleozoic coal seams are mainly of Mississippian age (Carboniferous). They are of continental origin and their reduced thickness and ash content are their main characteristics. Mesozoic coal seams (Upper Jurassic-Lower Cretaceous) are located in the so-called Peruvian Western Basin and in the depressions close to the 'Maranon Geoanticline'. They were originated in deltaic facies under the influence of brackish and fresh waters. Some of these coal basins (those distributed in the central and northern parts of Peru) are relatively well known because they are of economic importance. Finally, Cenozoic coal seams (Tertiary) are found in both paralic and limnic basins and their reserves are limited. All the Peruvian coals are of humic character and are vitrinite-rich. Their rank is highly variable and normally related with the different orogenic events which strongly affected this region. Thus, Paleozoic and Mesozoic coals are of bituminous to anthracite/meta-anthracite coal rank while peats, lignite and subbituminous coals are found in Cenozoic basins.

  1. Gold, coal and oil.

    Science.gov (United States)

    Dani, Sergio U

    2010-03-01

    Jared Diamond has hypothesized that guns, germs and steel account for the fate of human societies. Here I propose an extension of Diamond's hypothesis and put it in other terms and dimensions: gold, coal and oil account not only for the fate of human societies but also for the fate of mankind through the bodily accumulation of anthropogenic arsenic, an invisible weapon of mass extinction and evolutionary change. The background is clear; arsenic species fulfill seven criteria for a weapon of mass extinction and evolutionary change: (i) bioavailability to all living organisms; (ii) imperceptibility; (iii) acute toxicity; (iv) bioaccumulation and chronic toxicity; (v) adverse impact on reproductive fitness and reproductive outcomes and early-age development and growth in a wide range of microbial, plant and animal species including man; (vi) widespread geographical distribution, mobility and ecological persistence on a centennial to millennial basis and (vii) availability in necessary and sufficient amounts to exert evolutionarily meaningful effects. The proof is becoming increasingly feasible as human exploitation of gold, coal and oil deposits cause sustainable rises of arsenic concentrations in the biosphere. Paradoxically, humans are among the least arsenic-resistant organisms because humans are long-lived, encephalized and complex social metazoans. An arsenic accumulation model is presented here to describe how arsenic accumulates in the human body with increasing age and at different provisionally safe exposure levels. Arsenic accumulates in the human body even at daily exposure levels which are within the lowest possible WHO provisional tolerance limits, yielding bodily arsenic concentrations which are above WHO provisional limits. Ongoing consequences of global scale arsenic poisoning of mankind include age-specific rises in morbidity and mortality followed by adaptive changes. The potential rise of successful forms of inborn resistance to arsenic in humans

  3. Nitrogen release during coal combustion

    Energy Technology Data Exchange (ETDEWEB)

    1995-02-01

    Experiments in entrained flow reactors at combustion temperatures are performed to resolve the rank dependence of nitrogen release on an elemental basis for a suite of 15 U.S. coals ranging from lignite to low-volatile bituminous. Data were obtained as a function of particle conversion, with overall mass loss up to 99% on a dry, ash-free basis. Nitrogen release rates are presented relative to both carbon loss and overall mass loss. During devolatilization, fractional nitrogen release from low-rank coals is much slower than fractional mass release and noticeably slower than fractional carbon release. As coal rank increases, fractional nitrogen release rate relative to that of carbon and mass increases, with fractional nitrogen release rates exceeding fractional mass and fractional carbon release rates during devolatilization for high-rank (low-volatile bituminous) coals. At the onset of combustion, nitrogen release rates increase significantly. For all coals investigated, cumulative fractional nitrogen loss rates relative to those of mass and carbon passes through a maximum during the earliest stages of oxidation. The mechanism for generating this maximum is postulated to involve nascent thermal rupture of nitrogen-containing compounds and possible preferential oxidation of nitrogen sites. During later stages of oxidation, the cumulative fractional loss of nitrogen approaches that of carbon for all coals. Changes in the relative release rates of nitrogen compared to those of both overall mass and carbon during all stages of combustion are attributed to a combination of the chemical structure of coals, temperature histories during combustion, and char chemistry.

    2013-12-01

    Results of many years of investigations of plasma-chemical technologies for pyrolysis, hydrogenation, thermochemical preparation for combustion, gasification, and complex reprocessing of solid fuels and hydrocarbon gas cracking are represented. Application of these technologies for obtaining the desired products (hydrogen, industrial carbon, synthesis gas, valuable components of the mineral mass of coal) corresponds to modern ecological and economical requirements to the power engineering, metallurgy, and chemical industry. Plasma fuel utilization technologies are characterized by the short-term residence of reagents within a reactor and the high degree of the conversion of source substances into the desired products without catalyst application. The thermochemical preparation of the fuel to combustion is realized in a plasma-fuel system presenting a reaction chamber with a plasmatron; and the remaining plasma fuel utilization technologies, in a combined plasma-chemical reactor with a nominal power of 100 kW, whose zone of the heat release from an electric arc is joined with the chemical reaction zone.

    The burner for combustion of coal dust fuel, primarily, in rotating furnaces, contains coaxially disposed pipes, a branch pipe for feeding in the air mixture and a rotating mechanism. The first two pipes are switched in to an air source. The third pipe on the input end has an oblique section and the pipe may be rotated around an axis by a mechanism. The first pipe has ports and it may be moved in an axial direction. By installing the third pipe in the first and second positions, it is possible to direct the dust coming from the branch pipe along the central (the larger part of the dust) or the central pipe, respectively, which makes it possible to regulate the configuration of the torch and its temperature. Hot air is sucked from the furnace through the ports in the perforated first pipe to the mouth of the burner, which makes it possible to intensify combustion. By moving the fifitpipe to the right it is possible to overlap the ports with the projections and to rule out suction of the air. The possibility of regulating combustion in wide ranges makes it possible to reduce the expenditure of fuel by 2 to 3 percent.

    The Ceshui Formation coal is mostly anthracite and its metamorphism has been less documented.By analyzing systematically the reflectance of vitrinite and the results of X-ray diffraction of the Ceshui Formation cola in the Lianyuan coal basin,the spatial variation characteristics of coal ranks,coal metamorphic regions,the extension of coal metamorphic belts.coal metamorphic gradients,coal chemical structure and the effect on the degree of metamorphism of heat-production and -storge conditions,buried depth of the Indosinian-Yenshanian granites at the margins of the Lianyuan coal basin are discussed.The research results in conjunction of the features of regional hydrothermal alterations,endogenetic deposits with the Ceshui Formation coal measures,and the development of secondary vesicles indicate that the telemagmatic metamorphism is the main factor leading to the metamorphism of the Ceshui Formation coal in the region studied.

  12. Carbon dioxide from coal combustion: Variation with rank of US coal

    Science.gov (United States)

    Quick, J.C.; Glick, D.C.

    2000-01-01

    Carbon dioxide from combustion of US coal systematically varies with ASTM rank indices, allowing the amount of CO2 produced per net unit of energy to be predicted for individual coals. No single predictive equation is applicable to all coals. Accordingly, we provide one equation for coals above high volatile bituminous rank and another for lower rank coals. When applied to public data for commercial coals from western US mines these equations show a 15% variation of kg CO2 (net GJ)-1. This range of variation suggests reduction of US CO2 emissions is possible by prudent selection of coal for combustion. Maceral and mineral content are shown to slightly affect CO2 emissions from US coal. We also suggest that CO2 emissions increased between 6 and 8% in instances where Midwestern US power plants stopped burning local, high-sulfur bituminous coal and started burning low-sulfur, subbituminous C rank coal from the western US.

    2008-06-15

    The Cline Mining Corporation has proposed an open-pit mine to extract 2 million tonnes of coal annually in the Flathead Valley of British Columbia (BC). The Flathead Valley is known internationally for the richness of its flora and fauna. After the Flathead River crosses the border into Montana, it is managed under the most restrictive environmental protection laws available in the United States. The project is expected to be the first in a series of energy projects that will ravage the valley in the near future. Major energy companies are planning to open mines at sites within the Flathead River flood plain. The low quality coal obtained from the valley will be used to supply the unregulated economies of China, India, and Brazil. The valley is situated at the convergence of several biogeoclimatic zones and is home to a rich mix of plants and animals, including the highest concentration of grizzly bears in North America. The BC government's regulatory mechanism is not able to prevent exploitation of the region. Scientists from around the world have unanimously agreed that the mine should not be opened. Tailings from other mines currently draining into the Flathead River are now beginning to alter the river's chemistry. The federal government has been unsuccessful in its bid to create a national park in the region. It was concluded that unless land use regulations for the area are changed, the valley will inevitably be developed. 13 figs.

    Although remarkable progress has been made in developing technologies for the clean and efficient utilization of coal, the biggest challenge in the utilization of coal is still the protection of the environment. Specifically, electric utilities face increasingly stringent restriction on the emissions of NO{sub x} and SO{sub x}, new mercury emission standards, and mounting pressure for the mitigation of CO{sub 2} emissions, an environmental challenge that is greater than any they have previously faced. The Utah Clean Coal Program addressed issues related to innovations for existing power plants including retrofit technologies for carbon capture and sequestration (CCS) or green field plants with CCS. The Program focused on the following areas: simulation, mercury control, oxycoal combustion, gasification, sequestration, chemical looping combustion, materials investigations and student research experiences. The goal of this program was to begin to integrate the experimental and simulation activities and to partner with NETL researchers to integrate the Program's results with those at NETL, using simulation as the vehicle for integration and innovation. The investigators also committed to training students in coal utilization technology tuned to the environmental constraints that we face in the future; to this end the Program supported approximately 12 graduate students toward the completion of their graduate degree in addition to numerous undergraduate students. With the increased importance of coal for energy independence, training of graduate and undergraduate students in the development of new technologies is critical.

    Full Text Available Due to the policy of the European Union, it is necessary to search for new sources of scarce raw materials. One of these materials is germanium, listed as a critical element. This semi-metal is widely used in the electronics industry, for example in the production of semiconductors, fibre optics and solar cells. Coal and fly ash from its combustion and gasification for a long time have been considered as a potential source of many critical elements, particularly germanium. The paper presents the results of germanium content determination in the Polish hard coal. 23 coal samples of various coal ranks were analysed. The samples were collected from 15 mines of the Upper Silesian Coal Basin and from one mine of the Lublin Coal Basin. The determination of germanium content was performed with the use of Atomic Absorption Spectrometry with Electrothermal Atomization (GFAAS. The investigation showed that germanium content in the analysed samples was at least twice lower than the average content of this element in the hard coals analysed so far and was in the range of 0.08 ÷ 1.28 mg/kg. Moreover, the content of Ge in the ashes from the studied coals does not exceed 15 mg/kg, which is lower than the average value of Ge content in the coal ashes. The highest content of this element characterizes coals of the Lublin Coal Basin and young coals type 31 from the Vistula region. The results indicate a low utility of the analysed coal ashes as a source of the recovery of germanium. On the basis of the analyses, the lack of the relationship between the content of the element and the ash content in the tested coals was noted. For coals of the Upper Silesian Coal Basin, the relationship between the content of germanium in the ashes and the depth of the seam was observed.

    The coal deposits of Mongolia tend to become younger from west to east and can be subdivided into two provinces, twelve basins, and three areas. Main controlling factor of coal rank is the age of coal bearing sequences. Western Mongolian coal-bearing province contains mostly high rank bituminous coal in strata from Late Carboniferous. The basins in southern Mongolia and the western part of central Mongolia have low rank bituminous coal in strata from the Permian. The northern and central Mongolian basins contain mainly Jurassic subbituminous coal, whereas the Eastern Mongolian province has Lower Cretaceous lignite. Mongolian known coking coal reserves are located in western, southern and northern Mongolia and related to Carboniferous, Permian and Jurassic sequences, respectively. Pennsylvanian Nuurstkhotgor coal deposit is located in northwestern Mongolia (in Western Mongolian coal-bearing province). The coals have 1-7.5 crucible swelling number (CSN) and 0-86 G-index. Vitrinite reflectance value (Rmax in oil) varies from 0.7% to 1.2% and sulfur content is low, ranging from 0.3% to 0.6% with an average of 0.4%. Coal reserve is estimated to be 1.0 billion ton, of which half is coking coal. Upper Permian Khurengol deposit is situated in western Mongolia (in Western Mongolian coal-bearing province). CSN and G-index of coal are 8-9 and 54-99, respectively. The coals have Rmax of 1.1 to 1.7% (average 1.4%) and sulfur content of 0.2 to 0.6% (average 0.4%). Coking coal reserve of the deposit is estimated to be 340 million ton. Upper Permian Tavantolgoi, the largest coking coal deposit, lies in southern Mongolia (in South Gobi coal-bearing basin). The coals have CSN of 1 to 7.5 and Rmax of 0.7% to 1.2%. Sulfur content is low, ranging from 0.5% to 0.9%. Coal reserve is estimated to be 6.0 billion ton, of which 2.0 billion ton is accounted as coking coal. Lower-Middle Jurassic Ovoot coal is located in northern Mongolia (in Orkhon-Selenge coal-bearing area). This is one of

    Carbon foams were obtained from several bituminous coals with different plasticity and volatile matter content by a two-stage thermal process. The first stage, a controlled carbonisation treatment under pressure at 450-500{sup o}C, is responsible for the final textural properties of the foam. In the second stage the carbonisation product was baked at 1100{sup o}C. The foams produced display a macroporous texture with plasticity, volatile matter content and maceral composition of the precursor coals having an influence on the apparent density and the pore size of the resultant porous products. 7 refs., 4 figs., 3 tabs.

    Enteric fever (typhoid and paratyphoid) remains a threat to British troops overseas and causes significant morbidity and mortality. We report the case of a soldier who developed typhoid despite appropriate vaccination and field hygiene measures, which began 23 days after returning from a deployment in Sierra Leone. The incubation period was longer than average, symptoms started 2 days after stopping doxycycline for malaria chemoprophylaxis and initial blood cultures were negative. The Salmonella enterica serovar Typhi eventually isolated was resistant to amoxicillin, co-amoxiclav, co-trimoxazole and nalidixic acid and had reduced susceptibility to ciprofloxacin. He was successfully treated with ceftriaxone followed by azithromycin, but 1 month later he remained fatigued and unable to work. The clinical and laboratory features of enteric fever are non-specific and the diagnosis should be considered in troops returning from an endemic area with a febrile illness. Multiple blood cultures and referral to a specialist unit may be required.

    Full Text Available Roman Vindolanda lies on the Stanegate Road to the south of Hadrian's Wall, on the northern frontier of the Romano-British province. It has complex stratigraphy with at least ten layers of occupation dating from around AD 85 to its abandonment in the 5th century, but it is the first five levels from AD 85 to AD 130-139 that have produced some of the most significant organic objects from the Empire, including the Vindolanda writing tablets (Birley 2009. One of the distinctive aspects of the Vindolanda collection is the large number of wooden hair combs found in these levels. Over 160 boxwood hair combs have been unearthed from the site. Resembling modern nit combs, these small objects had the primary function of cleaning and detangling hair, but further examination of the collection allows for the exploration of different aspects of style and function.

    Full Text Available The European Union project is strongly challenged today by the historical decision of United Kingdom’s citizens to exit from this structure, with all consequences assumed. United Kingdom will be the first nation that will quit this ambitious initiative and the decision is transmitted by the organized national referendum’s results in this respect. The population’s opinion expressed by a huge number of voting persons should be taken into consideration by British politicians and transposed very soon into political actions that could have a strong and clear economic impact on both sides. This paper will discuss the possible economic consequences of such historical decision, including potential effects on a small country like Romania.

    British missionary Timothy Richard came to China, actuated by preaching the Gospel andexpanding the sphere of Christian influence. Considering some complex reasons for history, civilization,ideology and custom etc, he paid attention to secular education as well as doing missionary work to attainhis Christian goal. He laid much stress on the function of education, so he proposed Chinese governmentshould set up Educational Department. In the late Qing Dynasty, he participated in the organization andmanagement of Shanxi Imperial University. Under the circumstances of modern times of China, when it wasin the grip of national crisis, and the contradictory between China and foreign countries was acute andcomplicated, all the work he had done exerted objective influences in many aspects. While it reflected thestrong semi-colonial character in modernization of Chinese education, it had some positive effect as well.

    Full Text Available Genetic testing in children raises many important ethical, legal, and social issues. One of the main concerns is the ethically inappropriate genetic testing of minors. Various European countries established professional guidelines which reflect the different countries perspectives regarding the main ethical issues involved. In this paper, we analyze the Italian and the British guidelines by highlighting differences and similarities. We discuss presymptomatic, predictive, and carrier testing because we consider them to be the more ethically problematic types of genetic testing in minors. In our opinion, national guidelines should take into account the different needs in clinical practice. At the same time, in the case of genetic testing the national and supranational protection of minors could be strengthened by approving guidelines based on a common framework of principles and values. We suggest that the Oviedo Convention could represent an example of such a common framework or, at least, it could lead to articulate it.

    Coal is one of the most abundant energy resources in the US with nearly 800 million tons of it being mined annually. Process and environmental demands for low-ash, low-sulfur coals and economic constraints for high productivity are leading the coal industry to use such modern mining methods as longwall mining and such newer coal processing techniques as froth flotation, oil agglomeration, chemical cleaning and synthetic fuel production. All these processes are faced with one common problem area--fine coals. Dealing effectively with these fine coals during handling, storage, transportation, and/or processing continues to be a challenge facing the industry. Agglomeration by the unit operation of pelletization consists of tumbling moist fines in drums or discs. Past experimental work and limited commercial practice have shown that pelletization can alleviate the problems associated with fine coals. However, it was recognized that there exists a serious need for delineating the fundamental principles of fine coal pelletization. Accordingly, a research program has been carried involving four specific topics: (i) experimental investigation of coal pelletization kinetics, (ii) understanding the surface principles of coal pelletization, (iii) modeling of coal pelletization processes, and (iv) simulation of fine coal pelletization circuits. This report summarizes the major findings and provides relevant details of the research effort.

    During the years 1980-1996 a series of investigations related to the applied and theoretical aspects of the coal oil agglomeration processing were carried out in the Ukraine at the Donetsk State Technical University and Coal Chemistry National Academy of Sciences (NAN) of Ukraine, institutes UralVTI, VNIIPIHidrotruboprovod, LenNIlkhimmash, Kharkiv polytechnical Institute, Institute of Biocolloide Chemistry NAN of Ukraine and also at coal preparation plants and thermoelectric power stations in the Donbas. Theoretical bases of the process of selective oil agglomeration are developed on the basis of modern physical chemistry, physical-chemical hydrodynamics, adhesion theory, and solid fuel chemistry. The necessary sufficient conditions for aggregate forming coal and oil components in water have been formulated. The central problem of `coal-reagent` interaction during coal aggregation has been solved, and a mathematical description of processes for forming coal-oil aggregates including kinetics has been made. Analysis of factors which influence the process and its mathematical models have been realized. Rational conditions of pelletising of energetic and coking coal, coal raw material and products of coal preparation plants, electric power stations, and hydrotransport systems have been determined. Results of the complex study of technological properties of coal aggregates as objects of dewatering, hydrotransportation, consumption, coking, pyrolysis and carriers at gold adhesive preparation are presented. The theoretical principles and experimental data served as a basis for creating about 40 new methods and devices for the process of coal selective oil agglomeration. 14 refs., 7 figs., 1 tab.
