Coal: Anthracite, Bituminous, Coke, Pictures, Formation,

Coal is an organic sedimentary rock that forms from the accumulation and preservation of plant materials, usually in a swamp environment Coal is a combustible rock and, along with oil and natural gas, it is one of the three most important fossil fuels Coal has a wide range of uses; the most important use is for the generation of electricity  During the mining process of the nearvertical seam, there will be movement and collapse of the “roof side” rock layer and the Roof Fractures of NearVertical and Extremely Thick Coal

Coal mining and transportation Energy Information

Mining coal Coal miners use large machines to remove coal from the earth Many US coal deposits, called coal beds or seams, are near the earth's surface, but others are deep undergroundModern mining methods allow US coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978Coal is a sedimentary deposit composed predominantly of carbon that is readily combustible Coal is black or brownishblack, and has a composition that (including inherent moisture) consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material It is formed from plant remains that have been compacted, What is coal?
