Abstract
A re-tensionable cable bolt and related methods are provided. In one aspect of the invention, the bolt includes a sleeve for connecting or securing to a cable. The sleeve includes a lower end having a bore adapted for receiving a threaded shank for associating with a tension nut. A plurality of facets along a peripheral portion of the sleeve create corners that prevent the cable from rotating within the borehole during installation. The sleeve may be secured to the cable using resin, which forms another aspect of the invention.
