Open-pit mining - Wikipedia
Open-pit, open-cast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface.
Open Pit Mining Pros & Cons | Sciencing
Open pit mining is also called strip mining because the extraction process destroys vegetation, reduces habitats and pollutes the environment. Mining proponents argue that the process is more efficient, cost effective and safer than shaft mining. Environmental regulations help mitigate damage.

1.1 PHASES OF A MINING PROJECT - ELAW
1.1.3.1 Open-pit mining Open-pit 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 clear-cutting or burning of vegetation above the ore deposit may precede removal of the overburden. The
Effects of Gold Mining on the Environment | …
Two open-pit gold mines in Montana closed in 1998 but continue to cost the states taxpayers millions of dollars in reclamation and water-treatment efforts. Cyanide used at these mines to leach gold from ore resulted in such high levels of pollution that people cannot use nearby water resources until they have been subjected to extensive and expensive treatment and purification.
