Machines Used in Coal Mining Career Trend

2018-11-28  Twenty percent to 30 percent of mined coal underground is from longwall mining. This is performed by a mechanical cutter that shears coal off from a panel on the seam. 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.

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 ...

Longwall mining - Wikipedia

The only other machinery used was an electric cutter to undercut the coal face and electric drills for blasting to drop the face. Once dropped, manual labor was used to load coal on to the conveyor parallel to the face and to place wooden roof props to control the fall of the roof. Such low-technology longwall mines continued in operation into the 1970s. The best known example was the New ...
