Waste Rock Underground mining is conducted through adits or shafts by a variety of methods that include room-and-pillar, block caving, timbered-stope, open-stope, shrinkage-stope, sublevel-stope, and others. Waste removal is proportionately much less in underground than in surface mining, but it still requires surface waste disposal areas.
