Thrust Bolting: Roof Bolt Support Apparatus
The invention relates to a method for installing a roof bolt in a borehole of a rock formation and more specifically to tensioning the unit without the aid of a mechanical anchoring device or threaded tensioning threads. The bolt is capable of being placed into tension along the length and the levels of active support can be controlled by varying the length of the grouted portion and the level of thrust applied to the bolt during installation.
