Coal production using mountaintop removal mining

Types of surface mining techniques include contour strip, area, open pit, and mountaintop removal. In mountaintop removal, entire coal seams running through the upper portion of a mountain are mined by removing all of the overburden (rock or soil overlying a mineral

Top-producing Central Appalachia coal mines

The 25 highest-producing coal mines in Central Appalachia increased their output by 5.1% in 2018 compared to 2017. Total coal production at the mines increased to 33.4 tons, compared to 31.8 million tons in the year-ago period, according to an S&P Global Market Intelligence analysis of federal data.

Surface mining strip, open pit, mountaintop removal

Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed. It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels.. Surface mining is basically employed when deposits of commercially viable minerals or rock are found closer to the surface
