Surface mining. Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.

ICMM & Where and how does mining take place?

open-pit mining and quarrying – the recovery of materials from an open pit in the ground; strip mining – the targeted removal of surface layers to reveal the useful ore/seams underneath. By contrast, sub-surface mining consists of digging tunnels or shafts into the ground to reach deeply buried ore deposits.
