Machines Used in Coal Mining Career Trend

Surface Mining. For extracting coal which lies close the surface, huge drag-line shovel machines remove the topmost layers of soil and rock, exposing the coal, which is then removed by smaller machines. Surface mining may involve removing sections of hills or top layers of a flat surface area. The layers of rock and dirt covering the coal are

Mining Coal Coal Education

Continuous-mining machines are used to remove the coal. As the machine breaks the coal, large arms gather the coal on a conveyor belt. The conveyor belt then carries the coal away from the seam, and it is loaded into shuttle cars. The mining machine is then moved to the next area to be mined. This method of mining leaves almost half of the coal
