Open-cut mining is used when the minerals are found over a large area and relatively close to the surface. The open cut mine is dug downwards in benches or steps which slope towards the centre of the pit.Open-cut mining is when layers of earth are stripped away to reveal mineral deposits that are close to the surface. Mines are excavated over time in levels or benches. Benches are usually dug on four to sixty metre intervals and at an angle to reduce the risk of rock slides.

Open Cut Mining. There are many differences between open cut and underground mining. When minerals and deposits are found close to the surface and spread across a large distance, the best way to mine is to use the open cut mining method. In this process, the area is cleared of all topsoil and vegetation, this material is stockpiled and used later when rehabilitating the area once mining is finished.Open Cut Mining.
