Also see . . .  JOY Roof Supports, Giants of Longwall Mining. In longwall mining, powerful shearing machines drive back and forth across coalfaces of up to 400 metres (1300 feet) in length, producing coal at rates of up to one ton every second. What makes these impressive coal production rates possible are the massive hydraulic roof supports that shoulder the roof until the shearer has completed its pass.
