<p>As the depth of mining increases, the occurrence of seismic events is becoming a more common phenomenon causing serious problems regarding to the stability and safety of mines. However, seismicity and the accompanying rockburst phenomena are not a well-defined ...

<p>Over the last 30 years, a transition away from end-anchored bolts to fully grouted rock bolt systems has occurred in many underground mines. It seems geomechanically intuitive that the success of such bolts, which interfere with rock movements around underground ...

<p>Understanding the interaction between rock bolts and underground rock movement is critical for safe and cost effective underground excavation design. Although early research on this subject involved a balance of theoretical analysis and field measurement, ...

A new dynamic test facility has been established by the Western Australian School of Mines in Kalgoorlie. The facility uses the principle of ‘momentum transfer’ to dynamically load rock reinforcement systems and assess their suitability for use in rock burst ...

The main objective of this Project was to develop further, where necessary, and apply systems for insitu integrity testing of reinforcement tendons and grout, improved instrumentation for Quality Management of rockbolting and practical risk assessment techniques ...

The performance of reinforcement systems when subjected to dynamic loading may be substantially different to the performance measured in quasi-static tests. In order to investigate the extent of the differences in behaviour, a new testing facility has been ...

<p>The analytical design of rock bolt and shotcrete support of roofs of wide span tunnels under moderate cover in Sydney&rsquo;s Hawkesbury Sandstone is described. The simple process allows rapid parametric studies to be carried out prior to detailed numerical ...
Reference: Australian Geomechanics – June 2002
The recent advances in ground anchor technology and the related techniques of cable bolting and rock bolting are reviewed. Collectively the technology associated with the three techniques enable design engineers to address stability problems over a range of ...

<p>A series of pull tests were performed using fully-grouted seven-wire strand cable, in which the confining pressure at the outside of the cement annulus was maintained constant using a modified Hoek cell. The bond strength was shown to increase with confining ...

<p>This paper reviews physical means of slope stabilization, particularly subsurface drainage and rock / soil control and retention systems, which have been improved and technically advamced in recent years because of innovative changes in design, analysis ...
