Coal has been the worlds fastest growing energy source in recent yearsfaster than gas, oil, nuclear, hydro and renewable.101. What is coal? Coal is a fossil fuel, which is a combustible, s

12、edimentary, organic rock, and it is composed mainly of carbon, hydrogen and oxygen. It is formed from vegetation, which has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years to form coal seams. The build-up of silt and other s

13、ediments together with movements in the earths crust (known as tectonic movements) buried these swamps and peat bogs, often to great depths. 11 With burial, the plant material was subjected to high temperatures and pressures. This caused physical and chemical changes in the vegetation, transforming

14、it into peat and then into coal. Coal formation began during the Carboniferous Period(known as the first coal age), which spanned 360 million to 290 million years ago. 12 The quality of each coal deposit is determined by temperature and pressure and by the length of time in formation, which is refer

15、red to as its “organic maturity”. Initially the peat is converted into lignite or “brown coal”-these are coal-types with low organic maturity. In comparison to other coals, lignite is quite soft and its color can range from dark black to various shades of brown. 13 Over many more millions of years,

16、the continuing effects of temperature and pressure produces further change in the lignite, progressively increasing its organic maturity and transforming it into the range known as “sub-bituminous” coals. Further chemical and physical changes occur until these coals became harder and blacker , formi

17、ng the “bituminous” or “hard coals”. Under the right conditions, the progressive increase in the organic maturity can continue, finally forming anthracite. 142. Importance of Coal Due to its abundance , coal has been mined in various parts of the world throughout history and continues to be an impor

18、tant economic activity today. Compared to wood fuels, coal yields a higher amount of energy per mass and could be obtained in areas where wood is not readily available. Though historically used as a means of household heating, coal is now mostly used in industry, especially in smelting and alloy pro

19、duction, as well as electricity generation.15 Coal is one of the worlds most important sources of energy since the Industrial Revolution of the 1800s. As of 2010, coal is fuelling almost 40% of electricity worldwide. In many countries this figure is much higher: Poland relies on coal for over 94% of

20、 its electricity; South afric for 92%; China for 77%; and Australia for 76%. Coal has been the worlds fastest growing energy source in recent years-faster than gas, oil, nuclear, hydro and renewable.16 Over 6185 million tones (Mt) of hard coal is currently produced worldwide and 1042 Mt of brown coa

21、l/lignite. The largest coal producing countries are not confined to one region-the top five hard coal producers are China, the USA, India, Australia and South Africa. Much of global coal production is used in the country in which it was produced; only around 15% of hard coal production is destined f

22、or the international coal market.173. History of Coal Mining The Industrial Revolution, which began in Britain in the 18th century and later spread to continental Europe and North America, was based on the availability of coal to power steam engines. International trade expanded exponentially when c

23、oal-fed steam engines were built for the railway and steamships. The new mines that grew up in the 19th century depended on men and children to work long hours in often dangerous working conditions. There were many coalfields, but the oldest were in Newcastle and Durham, South Wales, Scotland and th

24、e Midlands, such as those at Coalbrookdale. 18 The oldest continuously worked deep-mine in the Unite Kingdom ia Tower Colliery in South Wales valleys in the heart of the South Wales coalfield. This colliery was developed in 1805, and its miners bought it out at the end of the 20th century, to preven

25、t it from being closed. Tower Colliery was finally closed on 25 January 2008, although production continues at the Aberpergwm drift mine owned by Walter Energy of the USA nearby. 19 Coal was mined in America in the early 18th century, and commercial mining started around 1730 in Midlothian, Virginia

26、. Coal-cutting machines were invented in the 1880s. Before this invention, coal was mined from underground with a pick and shovel. By 1912 surface mining was conducted with steam shovels designed for coal mining.4. Problems in Face of Coal Mining Despite the tremendous importance of coal, the indust

27、ry is faced with serious problems, such as:20 (1) Dust and noise pollution () Dust at mining operations can be caused by trucks being driven on unsealed roads, coal crushing operations, drilling operations and wind blowing over areas disturbed by mining. () Main sources of noise pollution are blasti

28、ng, movement of heavy earth moving machines, drilling and coal handling plants. (2) Mining subsidence Mine subsidence can be a problem with underground coal mining, whereby the ground level lowers as a result of coal having been mined beneath.21 The major factors affecting the extent of subsidence a

29、re seam thickness and its depth beneath the surface. Roof collapse will often start within 24 hours or coal extraction, but the full effects are transmitted rather slowly upwards, eventually resulting in subsidence at the surface. But it may be over 10 years before the surface is completely stable a

30、gain. (3) Water pollution Most underground and some surface mines lie well below the water table. 22 Both, therefore, have the potential to pollute any groundwater that flows through them. Waste water from coal preparation plant and mine water are other sources of water pollution. In addition to the

31、 obvious disturbance of the land surface, mining may affect to varying degrees, groundwater, surface water, aquatic and terrestrial vegetation, wildlife, soils, air, and cultural resources. Action based on environmental regulations may avoid, limit, control, or offset many of these potential impacts

32、, but mining will, to some degree, always alter landscape and environmental resources. 23 Regulations intended to control and manage these alterations of the landscape in an acceptable way are in place and are continually updated as new technologies are developed to improve mineral extraction, to re

33、claim mined lands, and to limit environmental impacts.24Unit 1 Coal Mine Geology and Exploration New words and expressions ancient einnt adj.古老的；远古的；古老的；远古的； 上古的；年老的上古的；年老的 microbial maikrobil adj.微生物微生物(细菌细菌)的的 reserve riz:v n.储量储量 extensive ikstensiv adj.延伸的，伸展的延伸的，伸展的 structure strkt n.构造构造,石理石理,
