Mark C, Tuchman RJ, Repsher RC, Simon CL, eds. Pittsburgh, PA: U.S. Department of the Interior, Bureau of Mines, SP-01-94, 1994 Aug; :1-145
This proceedings volume contains papers presented at the U.S. Bureau of Mines (USBM) technology transfer seminars on New Technology for Longwall Ground Control. These seminars were conducted in Washington, PA, on April 12, 1994, and Denver, CO, on May 10, 1994. The papers herein describe several new, highly practical USBM technologies now available for ground control in longwall mines, including the Coal Mine Roof Rating (CMRR), cable bolts, the MULSIM/NL numerical model, and the Wood Crib Performance Model. Other significant topics addressed include longwall panel layout, coal pillar design, horizontal stress in longwall mines, roof support selection for gate entries, and ground control monitoring.
