ABSTRACT:
A tensionable mine roof cable bolt having a resin grouted upper portion and a mechanically anchored lower portion. The lower portion includes a shaft which is swaged to the cable and accepts a mechanical anchor. The cable bolt is rotated during installation in a mine roof to mix resin and simultaneously engage the mechanical anchor with the rock. A drivehead attached to the lower end of the cable fails upon tensioning of the bolt to a predetermined load.
