• Open Pit Mining an overview ScienceDirect Topics

    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.

    Justification of Open Pit Mining Technology for Flat Coal

    The article describes a problem of considering the coal strata bedding for the scheming of dragline mining technology for open pits developing flat seams. For three flat coal seams strata processing the main criterion defining the choice of technology of their processing is the stratigraphic positioning rate for the middle coal seam. It is the ratio of the upper and lower interbeds height.

    The Thin Coal Seam (TCS) Mining Technology for Open

    Coal seam that is thinner than a certain value is defined as thin coal seams (TCS). It commonly occurs in China as it covers 84.2% of the mining area. This situation is even severe in China’s large surface coal mines, in which TCS accounts for 10–50% of the total reserve. Most TCS cannot be feasibly mined due to the working conditions of commonly used mining equipment.
