Shear characterisation of various cable bolts using single and double shear techniques

The application of cable bolts in Australian coal mines has been increasingly widespread over the past few decades. Cable bolts initially are installed as a secondary means of support systems in underground coal mines to complete the action of primary supports, rock bolts. Over the years, several investigations have been undertaken in order to better understand the mechanisms of rock and strata control to be able to more appropriately manage the environment of the ground. One of the most concerns amongst all researchers, which have been on increase, is to understand better the mechanism of load transferring systems in cable bolts. As a matter of fact, several investigations have been performed through utilizing Single and Double shear load test methodology to address the deficiency of previous studies and provide more credible and accurate database to be utilized by engineers and designers in order to create safer and more reliant environment in underground mining industry. The University of Wollongong in this regard has been playing a pivotal role to deal with the shortage of previous research studies in the field of Double and Single shear load tests and this thesis study continues the research work currently is going on at the research and development section of the University of Wollongong to enhance the scope of the previous studies.
