Open-pit mining - Wikipedia

Open-pit mining, also known as 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-air pit, sometimes known as a 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. It is applied to ore or rocks found at the surface because the overburdenis relatively thin or the

Slope stability in opencast mines and quarries

potential ground failure. As quarries and opencast mines develop over time, they usually get deeper and the overall slope angle becomes steeper which can increase the risk of rockfalls. Regular inspections of faces, haul roads and working benches will identify small scale rockfalls and failures that may indicate larger scale ground instability.
