open pit method of mining bitumen

  • Extraction of Resources

    Open-Pit Mining 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 Mining Methods

    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 limits of the ore pit to provide a bench, and the pit.

  • The impact of oil sands on the environment and health

    There are two primary extraction methods for oil sands: open-pit mining and in-situ mining The technique used depends on the depth of the deposit For example, in-situ mining is used when bitumen lies too deep beneath the surface for open-pit mining Injection of steam is used in both methods to heat the bitumen, which serves to make it more.
