Because of the high costs associated with supported and unsupported mining methods, open stoping with caving methods is used whenever feasible. Underground coal mining today is basically done by two methods room-and-pillar mining with continuous miners, and longwall mining with shearers.
In continuous mining, a machine known as a continuous miner cuts the coal from the mining face and deposits it directly into a haulage vehicle an efficient technique that obviates the need for drilling and blasting. Room-and-pillar mining in low seams is generally less efficient than longwall mining because as much as 50 of coal is lost.
