There are three basic types of surface mining: open pit mining, strip mining, and quarry mining.These methods are much more economical than underground mining, yet they can have a more significant impact on the surrounding environment unless efforts are taken to reclaim the land.

What are the pros and cons of strip mining?

Strip mining, removal of soil and rock (overburden) above a layer or seam (particularly coal), followed by the removal of the exposed mineral. The common strip-mining techniques are classified as area mining or contour mining on the basis of the deposit geometry and type.

A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

Jan 17, 2021 · What is Strip Mining? Surface mining, counting strip mining, mountaintop removal mining and open-pit mining, is a wide classification of mining where soil and rock covering the mineral source (the ‘overburden’) are gotten rid of, unlike underground mining (or deep mining) where the overlying rock is kept in place, and the mineral is taken out through shafts or tunnels.

Mar 15, 2012 · However, unless you're limited to mining certain chunks, you'll get better results by staying at layer 8-12 and just spreading out horizontally. The only purpose to strip mining is if you want to excavate a large area. Even if you want huge quantities of cobblestone, branch mining will generate plenty, and some good stuff to go with it.

Explanation: In strip mining, the ore is extracted from the surface in layers resulting in a deepening artificial valley. This is done when the ore is relatively near the surface. In underground mining, mine shafts are bored or dug from the surface to the underground layers where the ore is located, and ore extraction takes place from those layers, and the ore is transported through the tunnels and shafts back to the surface.
