Excavation Design and Sequencing in Highly Stressed Rock Masses. An increasingly large number of Australian underground mines are being operated in highly stressed rock mass conditions, where safe and economic mining is a real challenge due to rock mass instability. In the future, this problem will become more significant as extraction gets deeper with the discoveries of new deeper orebodies or the extension of current operations at depth. The aim of this research project is to provide the Austr ....Excavation Design and Sequencing in Highly Stressed Rock Masses. An increasingly large number of Australian underground mines are being operated in highly stressed rock mass conditions, where safe and economic mining is a real challenge due to rock mass instability. In the future, this problem will become more significant as extraction gets deeper with the discoveries of new deeper orebodies or the extension of current operations at depth. The aim of this research project is to provide the Australian mining industry with effective design tools to engineer the largest, most economical, yet stable excavations in rock. The research project will use a generalised framework for design where rock mass characterisation, excavation design, behaviour and dilution control will be studied in detail.Read moreRead less
Deep Coal Mining. The occurrence of progressively larger gas outbursts, coal bumps, and the potential for the catastrophic collapse of coal pillars is of increasing importance as mining drives deeper in seams rich in methane and other hydrocarbons. This study will address this issue by examining the roles of stress level, strain-rate, gas desorption rate, and drained and undrained gas and liquid pressures in the dynamic failure of coal, while simultaneously evaluating the promise and fidelity of ....Deep Coal Mining. The occurrence of progressively larger gas outbursts, coal bumps, and the potential for the catastrophic collapse of coal pillars is of increasing importance as mining drives deeper in seams rich in methane and other hydrocarbons. This study will address this issue by examining the roles of stress level, strain-rate, gas desorption rate, and drained and undrained gas and liquid pressures in the dynamic failure of coal, while simultaneously evaluating the promise and fidelity of a variety of hazard indices and precursive signals.Read moreRead less
The Influence of particle shape fragmentation and compaction on 3D hopper flow. According to world-leading material scientist Patrick Richard, "Granular materials are ubiquitous in nature and are the second-most manipulated material in industry (the first one is water)". Our research will produce massive three dimensional computer simulations predicting and analysing the influence of particle size and shape on the morphology of industrial and natural granular flows. The results will have directl ....The Influence of particle shape fragmentation and compaction on 3D hopper flow. According to world-leading material scientist Patrick Richard, "Granular materials are ubiquitous in nature and are the second-most manipulated material in industry (the first one is water)". Our research will produce massive three dimensional computer simulations predicting and analysing the influence of particle size and shape on the morphology of industrial and natural granular flows. The results will have directly and immediately relevant applications in a range of Australian industries, including mass mining and minerals processing and will further make a major contribution to understanding and modelling a variety of geo-hazards.
