Abstract:
A friction bolt assembly to frictionally engage a bore formed in rock strata includes an elongate tube and an expander mechanism acted on by an anchor mechanism via an elongate bar or cable. A retainer mechanism is mounted to act between the bar or cable and the tube to prevent ejection of the bar or cable from the assembly should the bar or cable break.

Claim (Index 1):
A friction bolt assembly arranged to frictionally engage an internal surface of a bore formed in rock strata, the assembly comprising:\n an elongate tube having a leading end and a trailing end; an expander mechanism located within the tube and towards or at the leading end and configured to apply a radial expansion force to the tube to secure the assembly to the rock strata; an elongate bar or cable extending longitudinally within the tube and connected at or towards a first end to the expander mechanism and at or towards a second end to an anchor mechanism positioned at or towards the trailing end of the tube; a retainer mechanism acting between the tube and the bar or cable such that at least a length portion of the bar or cable is prevented from the ejection from the assembly should the bar or cable break; and the anchor mechanism including a fixing mountable at or towards the second end of the bar or cable and configured to brace against the trailing end of the tube that by adjustment creates tension in the bar or cable to act on the expander mechanism and to create the radial expansion force, wherein at least a part of the fixing projects radially outward beyond the tube or a component attached to an external region of the tube arranged to be braced against the rock strata at a region around an external end of the bore.
