5203 |a“Rock anchors, i.e., tensioned cables or bars of much higher load capacity than conventional rock bolts, have been used for some time in civil engineering works and in some mining applications. It is expected that their use in mining will become more common. This report provides a summary of fabrication and installation procedures to guide engineers on mining properties"--Abstract, p. i.
