Machines Used in Coal Mining - Career Trend

More than two-thirds of coal extracted underground is done by a "continuous miner," a tractor with a mounted cylindrical grinder that breaks coal away from the seam. The continuous miner deliberately leaves undisturbed pillars of rock and coal in the mining area to create natural supports for the ceiling. This is known as "room and pillar" mining.
