Dowty Mining Equipment manufactured and supplied thousands of power roof supports and other mining equipment to the Longwall Mining process worldwide
Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice. The longwall panel is typically 3 – 4 km long and 250 – 400 m wide
It is a highly productive underground coal mining technique.
Longwall mining machines consist of multiple coal shearers mounted on a series of self-advancing hydraulic ceiling supports.
The entire process is mechanized.
