Abstract

A strata support system that provides support and balance to a rock mass and reacts to movement of the rock mass. The strata support system includes a borehole that is drilled into a surface of the rock mass. A resin is disposed in the borehole to secure a cable within the borehole. An anchor cable bolt assembly having a plurality of strands that are twisted together to form the cable is inserted into the borehole. At least one of the plurality of strands includes an interrupted outer surface that is defined by a plurality of spaced indentations. The plurality of spaced indentations are formed along the length of the strand and provide for a plurality of surface contours to enhance engagement of the anchor cable bolt with the resin.
