Underground mining: room-and-pillar mining of thick seams –“Benching” Different approaches allow either the top or bottom part of the seam to be mined out first.
In 2005, only 17% of metal mines were underground operations (Raw Materials Data, Stockholm 2010) but there are many instances where underground extraction of minerals is more cost-effective than surface mining, typically when the given ore body is high grade or very deep.
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
