OverviewMethods of extractionHistoryProductionModern miningSafetyEnvironmental impactsLegality of coal mining

Coal extraction methods vary depending on whether the mine is an underground mine or a surface (also called open cast) mine. Additionally coal seam thickness and geology are factors in selection of a mining method. The most economical method of coal extraction for surface mines is the electric shovel or drag line. The most economical form of underground mining is the long wall, which is a shear blade that runs along sections of the coal seam. Many coals extracted from both surface and underground mines requir

How Underground Mining Works HowStuffWorks

StoryExamplesComponentsCriticismsUnderground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers]. Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers. But those depths are extreme; most top (or bottom) out at about 1,000 feet (300 meters) [sources: Times Wire, ARMZ, Illi
