Open Pit Mining

Open Pit Mining

Surface mining is a process whereby soil and rock overlying the mineral deposit are removed. There are two principle types of surface mining, strip mining and open-pit mining (see Fig. 8.8). Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock.

There are two ways to mine a deposit. Some mines are open pit and others are underground. Choosing the mine type depends on a variety of factors such as deposit depth, deposit footprint, and extraction costs. Deposit depth: If the deposit is closer to the surface, an open pit mine is the preferred option.

Open-pit mining

Open-pit mining

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..
