A rock bolting system comprises independently movable hydraulic stinger, drill feed and bolting feed. The stinger is hydraulically extended to sting or engage the face of the rock. With the stinger stinging the rock face, the drill feed drills a hole in the rock. With the stinger still stinging the rock face, the bolting feed is indexed into position and a rock bolt is installed in the hole. A flexible elastomeric bolt centralizer may be mounted to the bolting feed to guide the rock bolt into the hole drilled by the drill feed.

A foldable feed rail for a rock drill is composed of two segments, a first beam defining a first rail segment and a second beam defining a second rail segment. The second beam may be pivotally connected to the first beam with a hinge to enable the second beam to be folded relative to the first beam. Alternatively, the second beam can be detachably connected to the first beam so that the second beam can be removed altogether from the first beam. This invention enables the feed rail to be shortened, thereby making the feed rail much easier to maneuver in mines.
