What Is Surface Mining? | Convergence Training

These mining categories are: strip mining, open-pit mining, mountaintop removal, dredging and high wall mining. All methods of surface mining will remove the waste material, or overburden, above the desired resource. Surface mining is often preferred to sub-surface (underground mining) by mining companies for several reasons.

Mining - Wikipedia

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Mining - Marspedia

Strip Mining. When resources are available close to the surface, a strip mine is the most efficient method of extraction. The layers of regolith covering the resource are taken away, and the exposed ore is mined. This method is also called open-pit mining, or regolith harvesting, depending on the depth of the work. Subsurface Mining Methods

What is the Difference between Strip mining and

3/12/2009· "Strip mining" is the practice of mining a seam of mineral by first removing a long strip of overlying soil and rock (the overburden). It is most commonly used to mine coal or tar sand. Strip mining is only practical when the ore body to be excavated is relatively near the surface.

Strip Mining - an overview | ScienceDirect Topics

Surface mining of coal is an alternative to underground mining, and it is practiced as strip mining, the most common form, and auger mining. Some coal is also produced through dredging and culm bank (i.e., anthracite waste piles) recovery, but these quantities tend to be relatively small compared to underground, strip, and auger mining.

5 Pros and Cons of Strip Mining Materials such as coal and tar sand are located relatively near the surface of the earth. The method to recover such materials is called strip mining, a form of surface mining where surface vegetation, soil and rocks are removed in strips and often times together with controlled explosions in order to make the removal process more efficient.
