<p>The Western Australian School of Mines (WASM) has developed a facility for the static testing of full scale ground support elements. The test facility consists of several stiff steel frames used to support the sample and a screw feed jack is used to load ...

An extensive axial test program has been used to quantify the difference between the static and dynamic capacities (kN/m of embedment) for friction rock stabilisers once sliding starts. Rough simulated boreholes have been developed for the installation and ...

A systematic program of testing of different reinforcement systems has been undertaken since 2004. Potentiometers, load cells, accelerometers and high speed video are used to monitor the tests. Software has been developed to analyse the data. The results from ...

Wire mesh has been used for surface ground support in mining since the 1950s. Experimental studies have been conducted throughout the world. The response of the mesh is dependant on the sample size, the boundary restraint systems and the loading conditions. ...

A punch test method has been developed to assess the performance of shotcrete and membranes. Each sample is sprayed onto a rock substrate containing a loading disc. The sample is rotated 180 degrees, placed onto the sample frame and constrained on all sides. ...

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 ...

<p>A review of the most widely used global extraction sequences in sublevel is undertaken. The review includes techniques used to extract massive as well as single or multiple steeply dipping tabular orebodies. The paper also deals with thick flat lying orebodies ...
