Underground mining is conducted through adits or shafts by a variety of methods that include roomandpillar, block caving, timberedstope, openstope, shrinkagestope, sublevelstope, and others. Waste removal is proportionately much less in underground than in surface mining, but it still requires surface waste disposal areas.
