Summary:A multiple cable rock anchor comprising an assembly of a plurality of individual elongated cables having an attachment for joining a first end of each cable in association for common movement, or wrapped to loosely hold them together without restricting relative sliding movement in bending. The assembly of multiple cable rock anchor being manipulated by bending for installation in a borehole formed in a geologic structure where there is a drift dimension less than the desired length dimension of the elongated cables, thereby forcing the cables to be bent upon being inserted in the borehole. Further, the assembly of cables have different strengths, dimensions and lengths.
