simple coal production process

Many U.S.coalbeds are very near the ground’s surface, and about two-thirds ofcoal productioncomes from surface mines. Modern mining methods allow us to easily reach most of ourcoalreserves. Due to growth in surface mining and improved mining technology, the amount ofcoalproduced by one miner in one hour has more than tripled since 1978.

In surface mining, the ground covering thecoalseam (the overburden) is first removed to expose thecoalseam 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 thecoalseam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the ...
