An investigation into the relationships between geology, geometry and wind blast magnitude & intensity in underground coal mining. In some underground coal mines where the roof comprises massive rock, the roof strata do not cave regularly as extraction progresses but hang up, leading to extensive areas of unsupported roof. These areas can suddenly collapse, compressing the air beneath and forcing it out of the void through surrounding openings giving rise to a potentially hazardous phenomenon kn ....An investigation into the relationships between geology, geometry and wind blast magnitude & intensity in underground coal mining. In some underground coal mines where the roof comprises massive rock, the roof strata do not cave regularly as extraction progresses but hang up, leading to extensive areas of unsupported roof. These areas can suddenly collapse, compressing the air beneath and forcing it out of the void through surrounding openings giving rise to a potentially hazardous phenomenon known as wind blast. The aim is to develop a fundamental understanding of the phenomenon and thus provide a basis on which to develop strategies to mitigate the hazard. Outcomes are expected to be improved levels of mining safety, technical viability and economics.Read moreRead less
Fundamental theoretical investigation of the chemomechanical properties of clays. Australia faces significant environmental challenges, one of the most important being soil degradation. The aim of this project is to develop new and state-of-the art mathematical models describing the behaviour of clays in soils. This proposal addresses five fundamental problems in clay soil behaviour that have so far remained unanswered. The primary outcomes of this project will be new theoretical insights into t ....Fundamental theoretical investigation of the chemomechanical properties of clays. Australia faces significant environmental challenges, one of the most important being soil degradation. The aim of this project is to develop new and state-of-the art mathematical models describing the behaviour of clays in soils. This proposal addresses five fundamental problems in clay soil behaviour that have so far remained unanswered. The primary outcomes of this project will be new theoretical insights into the chemomechanical properties of clay soils, so providing the understanding required to intelligently engineer and manage our natural and built environments.Read moreRead less

Summary
Advanced Testing Facility for Geological Sequestration of Greenhouse Gases. Predicted climate changes can cause disastrous impacts on nation's human health, agriculture, infrastructure and natural ecosystems. The reduction of greenhouse emissions as required by Kyoto Protocol while protecting Australian industries and jobs is a massive challenge. The long-term sequestration of CO2 in deep geological formations is considered to be the most viable solution. This technology, however, is at its i ....Advanced Testing Facility for Geological Sequestration of Greenhouse Gases. Predicted climate changes can cause disastrous impacts on nation's human health, agriculture, infrastructure and natural ecosystems. The reduction of greenhouse emissions as required by Kyoto Protocol while protecting Australian industries and jobs is a massive challenge. The long-term sequestration of CO2 in deep geological formations is considered to be the most viable solution. This technology, however, is at its infancy and a concerted national research effort is urgently required. The multi-user Facility will enable closer collaboration with researchers in academia and industry, and will be integral in training the next generation of Australian scientists in the geological sequestration and wealth from the earth and the ocean.Read moreRead less
Microstructural Analysis and Modelling of Copper Ore Agglomerates for Heap Leaching. The efficient extraction of valuable metals from mined ore can be considered as a problem of global concern as the world's reserves of such metals quickly diminish. For low grade copper ore, heap leaching has long been recognized as the most efficient mineral recovery procedure. This project aims to apply X-ray microtomography and micromechanical modelling to quantify the critical leaching properties of ore aggl ....Microstructural Analysis and Modelling of Copper Ore Agglomerates for Heap Leaching. The efficient extraction of valuable metals from mined ore can be considered as a problem of global concern as the world's reserves of such metals quickly diminish. For low grade copper ore, heap leaching has long been recognized as the most efficient mineral recovery procedure. This project aims to apply X-ray microtomography and micromechanical modelling to quantify the critical leaching properties of ore agglomerates and to formulate optimal heap leaching strategies. This will allow for better utilization of the Australia's low grade ore reserves. The procedures and methodologies to be developed will be applicable to other types of ore including gold, uranium and nickel.Read moreRead less
