Types Of Mining Equipment Use In Coal Mines

Products

  • Coal Surface Mining, Contour Mining

    Contour mining allows for the extraction of coal from mountainous areas, where it is not feasible to extract the entire seam, using mountain top removal mining. Contour mining allows for the partial removal of the coal seam at the elevation of the coal seam. Quite often, contour mining is utilized in more than one location on the same mountain.
