MINE WASTE MANAGEMENT
MINING AND ORE PROCESSING
Land Clearing Including
Removal of Topsoil and Subsoil
Each mining activity considered alone
is rather simple, but to optimize the
many contemporaneous activities
requires sophisticated planning and
scheduling.

Land Clearing
Land clearing is the i rst step in the physical preparation of the mine site. It leads to
the i rst signii cant visual impact, removes wildlife habitat, and predisposes the sur-
face to accelerated erosion by wind and water (discussed in detail in Chapter Twenty).
