What are the advantages of strip mining? What problems will there be in restoration of the mined lands?

Solution

Advantages of strip mining:-

1. It is more efficient compared to underground mining

2. The cost of strip mining is pretty low. Although powerful machines are used to uncover the overburden, this method of mining only touches the surface.

3. It is safer than underground mining.

4.Strip mining is also considered a much quicker procedure as tunnels don’t need to be dug and supported.

problems occur in restoration of the mined lands:-

Mining causes soil damage and destruction. In the process of removing the desired mineral material, original soils

become lost, or buried by wastes. in many countries legislation now requires that surface soils be conserved and

replaced, but there is a vast heritage of degraded land left by past mining that requires restoration.

Since the industry that created this heritage has often gone and there is no money left, the restoration needs to be

achieved as cheaply and yet as effectively as possible. The processes of natural succession demonstrate that

nature can achieve restoration unaided, and develop fully functioning soils
