ABSTRACT:
A method of roof/side wall roof bolting in-situ includes the steps of drilling a bore hole, loading a rupturable resin cartridge into a lightweight, tubular wand through the delivery end, manually placing the wand with the delivery end adjacent the mouth of the bore hole, pushing the cartridge through the wand for transfer into the bore hole, and inserting the roof bolt to rupture the cartridge and for setting into place in the rock. The related apparatus includes a tubular wand, a flexible pusher that is extensible through the wand and into the bore hole for transfer of the cartridge and a driver in the form of a flexible snake assembly from a reel to push the cartridge. The snake assembly includes a cylindrical head on the end and a plastic retainer fits over the trailing end of the cartridge to prevent retro movement and to provide protection from premature rupture. A handle at the proximate end of the wand provides for easy manipulation of the wand.
