Open-pit mining, or open-cast 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 tunneling into the earth, such as long wall mining.Open-pit mines are used when deposits of commercially useful minerals or rocks are found near the surface; that is.
