The Four Main Methods of Mining OreFlow
Strip mining is done only when the ore body is in close proximity to the surface Openpit mining – Openpit mining is the method in which minerals or rocks are extracted from the Earth via an open pit or borrow Mountaintop removal mining – Mountaintop removal mining (MTR) is done by mining coal seams underneath mountaintopsbackfillstrip mining technology is composed of backfill mining technology and caving mining technology,and a conventional subsidence prediction method, which has been proposed based on the implementation process of backfillstrip mining technology, has been used to predict the surface subsidence in backfillstrip mining (wang et al 2015; zhangSurface subsidence prediction method of backfillstrip

Contour strip mining is a method of surface mining or in which bulldozers, power shovels, or stripping wheels are used to remov e largeStrip mining is ideally applied where the surface of the ground and the ore body itself are relatively horizontal and shallow and where a wide area is available to be mined in a series of strips (Westcott, 2004) Table 2 provides some examples of the Australian surface coal minesSurface Coal Mining Methods in Australia IntechOpen
Room and Pillar Mining an overview | ScienceDirect Topics
Strip mining technology is an effective measure to reduce the overburden strata and surface movement and deformation, and it is also one of the important measures in the system of “Green Mining” Compared with the underground longwall mining, the surface subsidence with strip mining is smaller such that it can protect the surface buildings2 天前Mountaintop removal coal mining, often described as "strip mining on steroids," is an extremely destructive form of mining that is devastating Appalachia In the past few decades, over 2,000 miles of streams and headwaters that provide drinking water for millions of Americans have been permanently buried and destroyedWhat Is Mountaintop Removal Mining?
