Coal mining extraction of coal deposits from the surface of Earth and from underground Coal is the most abundant fossil fuel on Earth Its predominant use has always been for producing heat energy It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th

coal in the Powder River basin and the very large inexpensively minable surface deposits in the basin are economic barriers to under-ground mining in this region at least through-out this decade A potential method for recovering energy from coal is through in situ gasification of deep coal seams that cannot be mined by sur-face mining methods

The 4# Coal Seam of this coal mine is the thick coal seam with shallow buried depth which has the thickness of 12 m and the depth of 180 m in average This paper focuses on predicting the distribution of ground fissures and water-conducted fissures induced by the exploiting of the 4# Coal Seam

Coal Production Coal production is the amount of coal mined and taken to market Where does mining take place in the United States? Although coal is mined in 27 states more coal is mined in eastern states especially coal that is taken from underground mines than in western states

Strip mining of coal began around 1910 with the introduction of the steam shovel for removing the overburden By the 1960's more than half of the coal mined was by stripping From a record level of 1350 mines in 1935 the number of active coal mines has declined precipitously to about 20 today
