ABSTRACT:
A resin embedded rock bolt dimensioned to be inserted into a hole drilled in a rock body with a clearance fit between the bolt and hole, the bolt having a shank which is plastically deformed by the application of an eccentric shear force to form a paddle protruding beyond the undeformed exterior of the shank prior to deformation, the paddle being shaped to mix the resin.
