Abstract
A method of anchoring a spirally wound multi-strand cable in a borehole by using resinous material intermixed with the cable strands upon gripping the cable strands at one end to unwind the strands initially for forcing the cable into a borehole and for rewinding the strands to restore the cable to its spirally wound condition, and apparatus for applying cable rotating and thrusting reaction for securing retention of the cable in a borehole with a resinous anchor material.
