Open pit mining, also called surface mining, involves excavating minerals or rock that are close to the surface. There are two main types of mining methods: underground mining, which excavates deeper deposits; and surface mining, where the deposits are closer to the surface. Open pit mining involves digging a pit on the surface to extract near ...

Open-pit mines are dug on benches that are between four and sixty-meters in size, depending on the size of machinery used to excavate. The walls of most open-pit mines are dug at an angle and include steps to prevent avalanches from occurring inside the build site. The incline section of the wall is called the 'batter,' and the flat part of ...
