process of coal mining and machineries

To remove coal in these underground mines, miners ride elevators down deep mine shafts where they run machines that dig out the coal. 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 toremove dirt,rock,ash,sulfur,and other unwanted materials,increasing the heating…

    Coal has a variable chemical content. As for mining processes, they are quite variable. The most productive underground method is known aslongwall. A block of coal 200 to 300 meters wide and up to 10 kilometers long is defined by a set of tunnels. A cutting machine is then employed to cut the coal which is removed by conveyers.

    Coal mining by open-cut methods. A dragline is used to remove overburden from a gently dipping coal seam, placing it in spoil piles on the up-dip side (left). A pattern of blast holes has been drilled into the overburden on the right of the image. The coal is removed by apower shovel and placed into trucks for haulage from the mine.
