Abstract

A yielding spiral bolt appendage for attachment to a rock bolt has a cylindrical shank portion for attachment to the insertion end of the rock and a helical flute portion having a tip for rupturing a resin cartridge and achieving mixing when rotated. The shank has a first tapered portion and a second tapered portion for resisting movement of the appendage once the resin has set.
