descriptions of the most common methods. Openpit mining Openpit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clearcutting or burning of vegetation above the ore deposit

Underground mining (hard rock) Wikipedia

Selective mining methods. Cut and fill mining is a method of shorthole mining used in steeply dipping or irregular ore zones, in particular where the hanging wall limits the use of longhole methods. The ore is mined in horizontal or slightly inclined slices, and then filled with waste rock, sand or tailings.
