subsurface mining vs surface mining

Surface mining

Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.. Surface mining began in the mid-16th century [dubious ...

The Difference Between Underground Mining And Surface Mining

 · 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.

Pros and Cons of Mining

 · Acid rock drainage: Sub-surface mining require water to be pumped out of the mine to avoid any flooding. If the water is not pumped out, it results in the creation of acid rock drainage issue. 6. Destruction of the ecosystem: Clearance of the mining area and destruction of large portions of the forests lead to soil erosion in the area. 7.

Basic Information about Surface Coal Mining in Appalachia ...

 · Surface coal mining involves: removing parts or all of mountaintops to expose buried seams of coal, and. "interburden" (rock between coal seams). Overburden and interburden are disposed of in adjacent valleys because the broken rock will not all fit back into the mining pit, and disposal alternatives are limited.

Ch 15. Mineral Resources Flashcards | Quizlet

SURFACE MINING is the extraction of mineral and energy resources near Earth''s surface by first removing the soil, subsoil, and overlying rock strata. In STRIP MINING, a type of surface mining, a trench is dug to extract the minerals. SUBSURFACE MINING is the extraction of mineral and energy resources from deep underground deposits.

What is subsurface mining?

Room-and-pillar mining is a common method of subsurface mining. This method is used to extract salt and coal. A network of entries, called rooms, are cut into a seam, a horizontal layer of coal. Between the rooms, pillars of coal are left standing...
