    Mar 25, 2018 · They are two most basic methods that miners use to quarry coal. While surface mining is used for coal that can be found anywhere from the surface to 200 feet below, underground mining is used for coal that is loed lower. In surface mining, the top layer is removed which may include plants, soil rocks. This exposes the coal below the top layer.

    Methods in Surface Mining When the coal seams occur near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Open cast coal mining recovers a greater proportion of the coal deposit than underground methods.

    Sep 18, 2019 · Surface Mining. Surfacemining methods include area, contour, mountaintop removal, and auger. Area mines are surface mines that remove shallow coal over a broad area of fairly flat land. Huge dragline shovels remove rocks overlying the coal (called overburden). After the coal has been removed, the rock is placed back into the pit.
