    Open cut mining is the most economical means of mining; it removes the minerals closest to the surface which are easiest to extract, but also exposes the largest area of the underlying soil to erosion. The dumping of 'overburden' can form unvegetated hills that are a source of leachate and sediment, which may end up in waterways.How does mining affect erosion? Socratic,Aug 16, 2016· If you remove forest or green cover for mining, erosion will increase If you cut down trees, bushes, etc. to mine the area (as strip mining), the open area will be subject to erosion. Furthermore, the useless material that will be left without any cover will be subject to wind or water type erosion.
