  Coal - Wikipedia, the free encyclopedia
Coal (previously referred to as pitcoal or seacoal) is a fossil fuel extracted from the ground by underground mining or open-pit mining (surface mining).
Coal composition is determined by specific coal assay techniques, and is performed to quantify the physical, chemical and mechanical behaviour of the coal, including whether it is a good candidate for coking coal.
Coal liquefaction is one of the backstop technologies that will limit escalation of oil prices and mitigate the alleged effects of peak oil, provided that the extra carbon dioxide released in the process does not catastrophically accelerate global warming/adverse climate effects.

 EPA - Clean Energy - Electricity from Coal
Coal is a fossil fuel formed from the decomposition of organic materials that have been subjected to geologic heat and pressure over millions of years.
The coal is often cleaned or washed at the coal mine to remove impurities before it is transported to the power plant—usually by train, barge, or truck.
Coal mining can also contaminate bodies of water with heavy metals when the water used to clean the coal is discharged back into the environment.

 Coal Information
Coal is a fossil fuel and is classified into four types--anthracite, bituminous, sub-bituminous, and lignite.
And the thickness of a coal seam is not always consistent; many a mine has failed because the coal "pinched out." Over time, with the thrust of the Earth's plates, fault lines develop in coal seams, allowing for intrusions of mud and sediment--another hurdle for miners.
Coals that have been through a prep plant will serve you even better as they will have fewer impurities and be uniformly sized.
