Coal Mining. Health effects from coal mining include: the release of methane (CH 4), a potent greenhouse gas estimated to account for 18% of the overall global warming effect triggered by human activities (CO 2 is estimated to contribute 50%).; the release of carbon monoxide (CO) from explosives, which pollutes the air and poses a health risk for mine workers.
Natural Resources Severance Processing Tax E ffective June 1, 1980, the General Assembly levied a percent tax on the gross value of all minerals severed in Kentucky, including natural gas and natural gas liquids. Coal and oil were specifically excluded due to taxation under other statutes. The legislation imposed no minimum rate of tax per

Through coal handling preparation the optimal product mix can be developed Coal Low SG Rock High SG Middlings • Each pile of raw coal can be separated into groups according to density • As these groups are added together, an "YieldAsh" curve is formed • Every coal has a unique YieldAsh curve
Bituminous coal contains 45%–86% carbon and has two to three times the heating value of lignite. Bituminous coal was formed under high heat and pressure. Bituminous is the most abundant rank of coal found in the United States. Bituminous coal accounted for about 46% of coal production in 2017.
Preparation generally includes crushing the coal and removing heavy, extraneous noncoal materials. If coal is high in sulfur or other impurities, it is washed with a water or chemical bath, removing up to 40 percent of inorganic sulfur in the coal. Not all coal is prepared using the same process.

outside the mining area for placement and storage. In the Midwest, where the surface topography and coal seams are generally flat, it is common to employ area strip mining in which the fragmented overburden is placed directly by large draglines in the space created where coal has been mined ().In some situations in the eastern United States, a coal seam occurring near the top of mountains is ...
Global steel production is dependent on coal. Over 71% of the steel produced today uses coal. Metallurgical coal – or coking coal – is a vital ingredient in the steel making process. World crude steel production was billion tonnes in 2017.
coal preparation. The coal industry has grown at a phenomenal rate over the last 35 years, with saleable coal production increasing from 50 million tonnes (Mt) in 1968 to 227 Mt in 2001 (295 Mt Run of Mine) at an average compound growth rate of 5% per annum or an increase of Mt/annum. This growth, coupled with changes in both local and export
