How Underground Mining Works HowStuffWorks

Longwall mining is extraordinarily efficient. Rather than drilling through the ore deposit, a longwall machine cuts across it, shaving off slices up to 600 feet (182 meters) long. Those slices drop directly onto a continuously moving conveyor, which carries it to a haulage shaft that lifts it out of the mine.
