Coal mining

Longwall mining involves the full extraction of coal from a section of the seam, or 'face' using mechanical shearers. The coal 'face' can vary in length from 100-350m. Self-advancing, hydraulically-powered supports temporarily hold up the roof while coal is extracted. When coal has been extracted from the area, the roof is allowed to collapse.
