The Actual Difference Between Surface and Underground Mining

In all methods of surface mining, first, the overburden is stripped off using earthmovers.Then, bucket-wheel excavators remove the ore, which is loaded into haul trucks with shovel loaders. When the deposit is exhausted, the overburden is refilled in the crater, and the land is restored with the local vegetation.
