Method of application for FRP rock bolt
After the roofbolter finished drilling, remove the drill pipe, make the six-party of rock bolt installation machine insert jumbolter drill pipe connection, then make the lever genus part of compression nut insert the rock bolt installation machine, make anchoring agent into the rock bolt holes, then use the rock bolt bracing anchoring agent, at this time do propulsion leg movement, drilling machine motor not rotating, anchoring agent will be sent to the bottom of the hole, at this point to start drilling machine motor rotating, rotating rock bolt to stir anchoring agent, when the FRP rock bolt reached the bottom of the hole, stop the machine, drilling machine fast rotating to stirring anchoring agent, stirring time is set time of anchoring agent (usually 10 s ~ 15 s ), close the drilling machine, stop rotating, according to the anchoring agent curing time, general stop 30 s ~ 45 s, after anchoring agent curing, ant then make drilling machine to start rotating, screw up the nut for bottom of rock bolt, at this time drilling machine motor stop rotating, rock bolt install end
