Aug 26, 2021 The surface deformation caused by underground ore mining is a complex and changeable process, which is related to many factors. No matter what mining method is used and what the geological conditions are, the collapse and movement of rock strata are directly related to the surface deformation (Brown 2003; Charlie 2006).Therefore, it is of great significance to master the laws of rock collapse ...

Digging deeper Mining methods explained Anglo American

Large scale mechanised mining methods we use include: long-wall mining, where a long wall of coal is mined in a single slice, usually by a large machine. sub-level-caving, where levels of the ore are blasted by explosives; and ; block caving, where large areas of the ore body are blasted and then extracted with the assistance of gravity. We use these three different types of underground mining techniques for coal, diamonds and copper. 3. Underwater mining

The principal means of access to an underground ore body is a vertical opening called a shaft. The shaft is excavated, or sunk, from the surface downward to a depth somewhat below the deepest planned mining horizon. At regular intervals along the shaft, horizontal openings called drifts are driven toward the ore body.

How Are Diamonds Mined And Extracted From the Ground

This type of mining is usually performed in areas of secondary deposits like riverbanks, beaches or even off-shore locations. Alluvial mining involves the building of walls and the diversion of rivers. Once the water is emptied out and prevented from flowing into the area of interest, bulldozers are then used to exploit the ground of the riverbank.

Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.
