Explanation:

"Land reclamation" is a very important process in mining after the land is used for mining the land should return to its original use after the excavation and this process could start after the few hours of excavation.

When the mining is complete all the machines and related equipment of mining should be removed from that land, after returning the outlined land the top-soil of land replace.

The natural grass and seedling should plant and make sure the forest become productive as it was before mining, natural habitat for the wildlife.

Reclamation is complete only when the land becomes the same as it was before the mining.
