Cable Bolts for Longwall Gate Entry Support

• Description:
  Cable supports offer several advantages over traditional secondary support methods. Cable supports enhance stress redistribution to pillars and gob areas, minimize or eliminate timbers and cribs that reduce ventilation capabilities, eradicate material-handling injuries related to the placement of crib supports, and provide a cost-effective alternative to secondary support. The U.S. Bureau of Mines (USBM) has designed and installed cable supports to improve the stability of tailgate and bleeder entries in a western U.S. underground longwall mine. Design and installation techniques are presented for both cement and resin-grouted cable bolt systems. Three cable studies discuss the design philosophy, describe measurement instrumentation, and present the quantifiable results to date. [Description provided by NIOSH]
