machine required for coal mining

Machines Used in Coal Mining Career Trend

The panel being worked on may be up to 800 feet in width and 7,000 feet in length. Mined coal is deposited onto a conveyor that moves the coal to a collection area. Hydraulically powered shields over the machine provide ceiling support. Longwall mining is more efficient than room and pillar mining, but the equipment is more expensive.

Opencast Mining - an overview ScienceDirect Topics

Coal is mined either by surface methods (open-cut or open-cast mining) or by underground techniques. In surface mining, all of the rock from the ground surface to the top of the seam (material referred to as overburden) is removed and set aside to expose the coal, which is then taken out and transported from the mine for preparation and use ...

The plough height is the working height in the seam being mined (possibly a bit lower if the coal tops can be guaranteed to fall once the coal below is cut. These "picks" act in a fashion similar to chisels and break a narrow web of coal off the face (of the order of 300-400mm thick). In most cases there are no moving parts on a coal plough.
