Open Pit Coal Mining Equipment

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 …

Open pit mining equipment Open pit mining is an industrial activity that involves the removal of large quantities of soil and subsoil, which is then processed to extract the mineral. This mineral may be present in very low concentrations, in relation to the amount of material removed.
