is the deepest form of underground mining It involves excavating a tunnel from the top to the bottom area of the mine From this tunnel, the miners then dig long horizontal tunnels to get to the coal or other mineral ore The tunnels are dug deeper and longer until all the ore is extracted or it becomes too deep to worry about it.

Underground mines are the alternative to surface min 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.

Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels Surface mining is basically employed when deposits of commercially viable minerals or rock are found closer to the surface.
