Shearer mining Britannica
In 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 machineJoy introduced the first allelectric shearer in 1976 Since then, Joy shearers have been working in the world’s most productive longwall mines and in the most demanding conditions Models are available for seam ranges from 13 to 90 meters (43 to 30 ft)Joy Longwall Shearers Underground Mining Komatsu A shearer consists of a machine body containing electric motors, hydraulic equipment and controls which is mounted over the AFC Horizontal cutting drums are mounted on the face side of the machine, laced with cutting picks and rotating in a plane parallel to the faceEquipment underground COAL
