Question

Explain why mining soil loss on sloping land is better achieved by measures that retain much of the original vegetation cover rather than extensive clearance followed by replanting

Answer 1

It is studied that replanting after extensive clearance does not reduce the mining soil loss. By keeping the original vegetation cover, the soil is not being exposed to erosion or is not being dug which avoids times of excessive water penetration and land sliding as well as normal erosion from the slop gradient.
