Coal Mining –The 2 Most Basic Techniques Of Extraction ...

02/04/2021  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 located lower. In surface mining, the top layer is removed which may include plants, soil rocks. This exposes the coal below the top layer. It is then excavated out. Once all the coal has been removing, the top layer of soil and rock is returned to ...

advance mining, the coal closest to the shaft (excluding the shaft pillar) is removed first. As a mine is developed, the coal further from the shaft will be removed. Miners, equipment and coal are transported underground along horizontal tunnels called roadways. In retreat mining roadways are driven out to the furthest reach of the mine, and then coal is mined out on the return to the shaft. A ...
