Strip Mining - an overview ScienceDirect Topics

In strip mining, the overburden is mined and moved by the same equipment: draglines or continuous excavators. The movement of overburden in strip mining is called the casting process. The operating sequence for each pit includes drilling and blasting, followed by overburden casting, then coal removal.

Strip Mining - an overview ScienceDirect Topics

Minerals are typically excavated by underground mining, strip mining, or open-pit mining. The selection of the mine design is dictated by the physical structure and value of the ore body and by the characteristics of the adjacent geological materials. Although open-pit mines and underground mines are the two most common mining strategies, placer mining and solution mining also have been used for mineral

Strip Mining: A Destructive Way of Coal Extraction ...

The process of strip mining also lowers groundwater levels around the mine. In order to remove the coal, vast quantities of groundwater are pumped out of the mine and as a result, surrounding ecosystems and farmland may become drier, and erosion may start to change the landscape. Strip mining also uses significant amount of water to suppress dust.

What is the difference between strip mining and ...

10.10.2016  Strip mining is done on the surface; underground mining is done below the surface. 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

underground pit mining in the philippines, why is it

Surface mining—including open pit or strip mining—is less dangerous than underground mining, but has a greater impact on surface landscapes. Surface mining requires the removal of massive amounts of top soil (or overburden) in order to gain access to the coal seams, which can cause erosion, loss of habitat, and dust pollution.
