ABSTRACT:
A gooseneck interposed between a rock drill and supporting jack leg includes an offset pivot bearing for the rock drill and an adjacent pin to facilitate initial insertion of a friction rock stabilizer into a receiving hole. Use of the gooseneck involves alignment of the jack leg and stabilizer, followed by simultaneous operation of the rock drill and jack leg to force the stabilizer into the hole while vibrating it.
