What is the difference between an open-pit mine and an underground mine? Open pit mining is a technique used to extract copper ore near the earth's surface. Underground mining is used when the copper ore is not near the earth's surface. Miners dig a shaft into the ore deposit vertically or a horizontal tunnel (or adit) in order to do this.

OPEN PIT MINING: A method of mining by removing the overlying materials to extract the minerals from shallow depths. A QUARRAY: A place from where stones, minerals etc are extracted. SHAFT MINING: A method of mining where vertical and horizontal shafts are made to extract the minerals from deep under the earth.
Open cast mining-Essentially, overburden is removed, the exposed ore is recovered, and the pit is filled, progressively, by the next tranche of overburden.The working footprint of an opencast mine like Macraes in Otago would typically be up to 300 ha although the total area mined over time would be much greater than that. Shaft mining -
What is the difference between an open pit mine and underground mine with shafts? Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface.
