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 mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals.

The practice includes some of the largest machines on earth, removing long strips of overlying soil and rock and then removing coal deposits. Open-pit mining utilizes blasting and mineral removing, digger deeper into the earth causing a crater-like result.
The type of surface mining used depends on two factors: the resource being sought and the local topography. In open-pit mining machines dig holes and remove ores (of metals such as iron, copper, and gold), sand, gravel, and stone (such as limestone and marble).
