The cable bolt-grout displacement meter: An innovation in cable bolt monitoring

Cable bolting is a critical aspect of underground mining operation. While the cable bolt has effectively been used for many years now, still, failures occur in stopes which could have been limited with an alternate cable bolting design. The design of a cable bolt support system requires the understanding of the principles behind the cable bolting. This understanding comes both from experience and monitoring.;This report investigates the general principles and aspects of cable bolting and monitoring systems and further presents an innovation for cable bolt monitoring. The Cable Bolt Grout Displacement Meter or Cable-GDM is presented and laboratory testing confirms its effectiveness for the monitoring of the axially loaded cable bolts.
