    Jun 01 2020 Once the coal is removed the disturbed area may be covered with topsoil for planting grass and trees. About two-thirds of U.S. coal production is from surface mines because surface mining is less expensive than underground mining. Underground mining sometimes called deep mining is necessary when the coal is several hundred feet below the surface. Some underground mines are thousands of feet deep with tunnels that may extend out from the vertical mine

    Longwall mining extracts all machine-minable coal between the floor and ceiling within a contiguous block of coal known as a panel leaving no support pillars within the panel area. Panel dimensions vary over time and with mining conditions but currently average about 900 feet wide coal face width and more than 8000 feet long the minable extent of the panel measured in the direction of mining.

    Dec 22 2012 Surface Mining If coal is less than 61 meters 200 feet underground it can be extracted through surface mining. In surface mining workers simply remove any overlying sediment vegetation and rock called overburden. Economically surface mining is a cheaper option for extracting coal than underground mining. About two and a half times as much coal can be extracted per worker per hour than is possible with underground mining.

    Mine development. Coal can be extracted from the earth either by surface mining or underground mining. In open-pit coal mining a pit is dug in an area and this pit becomes the open-pit mine sometimes called a quarry.Open-pit mines can expand to huge dimensions until the coal deposit has been mined or the cost of transporting becomes too great.
