Appendix E: Coal Mining and Processing Methods | Coal ...

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 ...

Coke Manufacturing - IFC

In the coke-making process, bituminous coal is fed (usually after processing operations to con-trol the size and quality of the feed) into a series of ovens, which are sealed and heated at high temperatures in the absence of oxygen, typically in cycles lasting 14 to 36 hours. Volatile com-pounds that are driven off the coal are collected
