    2018-8-5 · The depth thickness and configuration of the coal seams determine the mode of extraction. Shallow flat coal deposits are mined by surface processes which are generally less costly (per ton of coal) than underground mines of similar capacity. Strip mining is one of the most economical surface processes. Here removal of overburden and coal extraction proceed in parallel strips along the face of the coal deposit with the spoil being deposited behind the operation in the previously mined areas. In open pit mining thick seams (tens of meters) are mined by traditional quarrying techniques. Underground mining is used for deep seams. Underground mining
