Abstract

A method and apparatus for rock bolting. The method comprises inserting into a hole a rock bolt (5) such that it has a threaded end protruding from the hole and its other end is in contact with resin components. A nut (7) is engaged with the thread and a rotation tool (81) is engaged with the nut and with a drive means such as a notch (51) on the bolt. Both nut (7) and bolt (5) are rotated together in a first direction in order to mix the resin components in the hole and the resin is allowed to set. The direction of rotation of the tool is then reversed to cause disengagement of the tool (81) from the drive means (51) on the bolt and cause the nut (7) to spin along the thread towards the rock. A bolt carrying a notch at its threaded end is described.
