Before any mining is begun, surface soil is stripped and stored for future use. The humus soil, which is 0.3–0.5 meters below the surface, is particularly important for supporting plant life. After mining at a particular location is complete, the stripped earth is stacked layer by layer and dumped into the open pits in a stepwise manner.

An Introduction To Surface Mining

Mining is merely defined as digging in the ground to find something of use. The process has been a part of life since antiquity, and is still the backbone of the world's commerce and production. Mining could be classified in two forms: mining at the earth's surface (surface mining) and mining underground (subsurface mining).
