Coal is a sedimentary rock, and bituminous coal frequently contains "bands," or strips, of different consistency that mark the layers of plant material that were compressed. Bituminous coal is divided into three major types: smithing coal, cannel coal, and coking coal.
In the most recent years for which production data from individual coal beds is available (1999-2003), production was recorded from 45 different coal beds. The Pocahontas No. 3 coal bed has been by far the most significant producer in recent years, followed by the Jawbone and Lower Banner coal beds. Total coal production by coal bed, 1999-2003

As the coal gangue is main solid waste for coal mining, one of the most common approaches to waste rock is to stack construction that encapsulate the most pyrite rich rocks in the core of a waste rock stack (Lottermoser, 2003, Williams et al., 2003).

Although the United States has the vast coal resource described in the previous chapter, perhaps as much as 4 trillion tons, the key issue for policy makers is the amount of coal that is economically recoverable. This is not a fixed quantity, but depends on the geological resource, the market price ...
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure.
Gray shale with plant fossils and carbonaceous (coaly) concentrations are common above many coal beds, especially in draw rock, or draw "slate." Draw rock or miner's "slate" is the rock immediately above coal beds which must be removed along with the coal bed during underground mining.
The Department of Mining Engineering, Center for Applied Energy Research, and Kentucky Geological Survey, all at the University of Kentucky, are testing Kentucky- mined coals and coal byproducts for their REE content and concentration, and testing the potential for commercial extraction of REEs from coal and coal byproducts.

Coal gangue is a rock included in the coal bed and a waste discharged during coal mining and transportation as well as the most industrial waste discharged in China. It is estimated [1, 2], that the amount of gangue calculated as 15% of the coal output, there would be 100 million ton increment annually. Most of the coal gangue is a clay
Coalbed methane (CBM or coal-bed methane), coalbed gas, coal seam gas (CSG), or coal-mine methane (CMM) is a form of natural gas extracted from coal beds. In recent decades it has become an important source of energy in United States, Canada, Australia, and other countries.
