Coal is an essential input in the production of steel. Steel is a man-made alloy of iron and carbon – and that carbon usually comes from coal. Almost 70% of the steel produced today relies directly on metallurgical coal, also referred to as coking coal. The remainder is produced by recycling scrap steel (itself originally produced directly ...

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 ...
