Other articles where Shearer is discussed: coal mining: Origins of longwall mining: .simple continuous machine called the shearer was introduced. Pulled along the face astride the conveyor, the shearer bore a series of disks fitted with picks on their perimeters and mounted on a shaft perpendicular to the face. The revolving disks cut a slice from the coal face as the machine.
Longwall mining has traditionally been a manual process in which alignment of the face equipment was done with string lines. Technologies have been developed which automates several aspects of the longwall mining operation, including a system that aligns the face of the retreating longwall panel perpendicularly to the gateroads.
to a longwall shearer has increased from 333 hp in 1977 to 403 hp in 1984 (12).5 In this study shearer motor en;rgy is defined as the kilowatthours of energy used by the shearer to cut 1 st of coal crete. The shearer motor energy is used as a measure of shearer cutting efficien cy.

developments since 1990 have once again established plowing as the preferred longwall mining method for seams below m (71 in). Cat plows offer worldleading features that other manufacturers cannot and a cost of ownership that far outstrips the shearer when mining thin and medium seams. Their reliability, highproductivity and ability to
The unique mainframe of the Cat shearer is one of its key features. The fabricated structure of the mainframe with cast rangingarm hinge points results in an extremely robust design not only to meet the toughest mining conditions and ensure reliability and long service life, but also to handle even higher cutting and haulage forces in the future.
