Abstract: The addition or removal of individual drill rods from the drill column of a raise drilling system is facilitated by a drill rod handling apparatus. The drill rod handling apparatus is attached to the support frame of the raise drill and includes arm means for moving individual drill rods into and out of the uppermost position in the drill column. Gripping elements are connected to the arm means for grasping and retaining an individual drill rod as it is being moved into and out of the drill column. The gripping elements include mechanical locking means for locking the gripping elements when the gripping elements are grasping and retaining an individual drill rod. A shock absorber means is connected to the arm means for absorbing the shock produced by vertical movement of an individual drill rod when the drill rod is contacted and engaged by the drill head of the raise drill.
