    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

    Open-pit mining occurs on surface and is generally the cheapest way to extract ore. This is because rock doesn’t have to be moved far up hill against gravity, equipment used can be larger than underground, and it doesn’t require more expensive features like ventilation, communications, etc. that underground does

    Apr 09, 2017 Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping. The stripping-pit limits must be extended beyond the
