How Underground Mining Works HowStuffWorksIn 2010, people everywhere were riveted to the story of the 33 miners in Chile trapped 2,300 feet (700 meters) underground in a copper and gold mine. The miners spent more than two months there, getting food, air and letters from loved ones through bore hills drilled to their location in a protected workroom. Meanwhile, the largerscale drilling of an escape shaft made slow progress. Finally, on Day 69, rescuers lifted each of the miners out alive [source: Boston]. The saga reminded the nonmining world of a usually invisible truth. Deep beneath the surface of the Earth lie some of the most frightening factories in the world: underground mines.

Underground 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 extrememost top (or bottom) out at about 1,000 feet (300 meters) [sources: Times Wire, ARMZ, Illinois Coal Association].
