Coal is an abundant natural resource that can be used as a source of energy, as a chemical source from which numerous synthetic compounds (, dyes, oils, waxes, pharmaceuticals, and pesticides) can be derived, and in the production of coke for metallurgical processes.
Jun 07, 2017· An Overview Of Coal Production In The US. Over 40% of coal mining and production in the US is done on public lands; however, mining had reduced marginally from billion short tons in 2008 to 986 million short tons in 2015. Wyoming, West ia, Kentucky, Illinois and Pennsylvania account for over 70% of the total coal industry in the US.
In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the ...
