This project contributes to an improvement in mining geomechanics through better understanding by geotechnical engineers of the behaviour of different types of cable bolts leading to more informed decision-making in the design of ground control systems leading to a safer working environment.

 

The aim of the project was to determine whether there are any differences in the performance characteristics of a number of cable bolts under varying geotechnical conditions for the benefit of the Australian underground coal mining industry and the people who work in the industry.

 

The specific objectives of this project were to:

· Validate and improve on, where required, the design of the test facility from the Stage 1 project;

· Compare the performance of five different types of cable bolts;

· Undertake a parametric study on the effects of grout strength, drill hole diameter and strength of confining medium; and

· Contribute to the decision-making process in the selection of appropriate cable bolts in different geotechnical conditions.
