When mining operations are complete, the overburden material is reapplied and leveled and then the topsoil is reapplied and spread over the overburden material to provide a planting medium (USDA Forest Service RM447). Both removal and replacement of the soil layers involves the use of heavy equipment.
The first step for any construction or mine site should be to identify and preserve natural vegetation to the greatest extent practicable.
