The Actual Difference Between Surface and Underground Mining

Surface mining can be accomplished by the following main methods: Open-pit Mining: Removing ore to leave a crater. Quarrying: An open-pit mine for construction materials. Strip Mining: Ore is removed in parallel strips. Mountaintop Removal: Top of a mountain is blasted to remove deep ore. Dredging: Ore is removed from a river bottom. The main methods of underground mining are:

Underground v.s. Surface Coal Mines: Is Mining Global

Underground mining. Underground or “deep” mining consist mostly of two methods room-and-pillar and longwall mining. In room-and-pillar, coal deposits are mined by cutting a network of “rooms” into the coal seam and leaving behind “pillars” of coal to support the roof of the mine.

Surface Mining, Industry of Metals, Minerals, Precious

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

Mining Underground mining | Britannica

Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on

The Difference Between Underground Mining And Surface Mining

Apr 21, 2014· Mining is conducted basically in two ways, either underground, or surface mining. Surface mines, or strip mines, are large pits where dirt and rock are removed to expose the minerals. 2. Underground mines are large tunnels that are dug deep into the ground to reach minerals that are too far underground to be reached from surface mines. Surface
