Review of Cable bolting installation methodology in Australian underground coal mines and the associated risks.
Research output: Thesis › Master's Thesis (University Course)
Gable bolts are substantially easier to fit into a bore hole than the elongated rods of conventional rod bolt systems. Regardless of the height limitations in a mine, cable bolts may be adapted to bore holes of any length due to their flexibility. The strength capacity of cables exceeds that of conventional rod bolts and, therefore, cable is the preferred reinforcement for certain roof conditions. Gonventional cable roof bolts are installed by placing a resin cartridge including catalyst and adhesive material into the blind end of a drilled hole, inserting the cable bolt into the drilled hole so that the upper end of the cable bolt rips open the resin cartridge and the resin flows in the annulus between the bore hole and the cable bolt, rotating the cable bolt to mix the resin catalyst and adhesive and allowing the resin to set about the cable bolt. Gable bolts have been primarily used as secondary roof support structures with tensionable rock bolts serving as the primary anchorage mechanism.
