In underground or deepshaft mining, minerals are extracted by making special underground workings. Depending on the working site, opencast mining of mineral deposits includes stripping (removal, haulage and removal of overburden), mining proper (extractions, haulage and storage or unloading of the mineral) and development work that consists in making permanent trenches and other workings, for instance, .

A combination of modern machines in Open Cast Mining like Walking Draglines, Shovels and High Capacity Dumpers were introduced in 1975. Inpit Crushing and Conveyor technology for Over Burden removal and coal extraction was commissioned for the first time in Ramagundam Open Cast Mine with German assistance in 1994.
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 may precede removal of the overburden.
