Description of case study mine For the present study various failure and maintenance information of a longwall shearer were collected from the maintenance records of an underground coal mine located in Southern India. Longwall technology was introduced in this mine in early 1990s and Þve panels have been extracted by retreat longwall mining.
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.
developments since 1990 have once again established plowing as the preferred longwall mining method for seams below 1.8 m (71 in). plows offer world-leading features that other manufacturers cannot and a cost of ownership that far outstrips the shearer when mining thin and medium seams. Their reliability, high-productivity and ability to
