Author: Brendan Crompton – BSc (Eng) (Mechanical), MBA
Date: 24 July 2018

This presentation considers the differences in performance of ground support under quasi-static and dynamic loading and the various types of dynamic testing currently available to the mining industry. Specific focus is given to the methodology and results achieved from the dynamic laboratory testing of rockbolts as well as the presentation and interpretation of test results. A practical approach to better utilise laboratory results for the monitoring of support performance underground is also proposed.
