Mine Tailings Disposal Methods

Room-and-pillar mining may leave as much as 60 percent of the coal in supporting pillars after initial mining. Later, some of these pillars are removed as equipment retreats from the mined area. Long-wall mining permits increased recovery of coal by extracting coal along a single face which is much longer than used in room-and-pillar mining.
