  • What are the processes and machinery required to extract

    Coal mines generally extract coal which is classified as a rock rather than a mineral. A mineral is considered to be a naturally ocurring substance with a definite chemical content. Coal has a variable chemical content. As for mining processes, they are quite variable. The most productive underground method is known as longwall. A block of coal 200 to 300 meters wide and up to 10 kilometers long is

  • How is coal mined and extracted? Planète Énergies

    The longwall method involves using a machine called a shearer Mechanical cutting machine used to extract coal in underground mines. that looks like a huge plow. The shearer slowly pushes and cuts through the coalface. It recovers the loosened ore as it advances and lets the roof collapse behind it. This is called caving. Sometimes buildings or roads located above the mine can be damaged as a result.

  • Machines Used in Coal Mining Career Trend

    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 reserved for until the coal is removed, at which point the the dirt and rock is

  • Coal Mining and Processing Energy Trends Insider

    Processing the Coal. After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal. Source: Energy Information Administration.
