This project will improve our understanding of non-linear flow and fracture phenomena in porous media which is prerequisite for the development of new emerging technologies targeting the reduction of the greenhouse gas emission and development of effective waste and water management solutions including coal gasification, in-situ storage of natural and non-hydrocarbon gases, underground disposal of hazardous wastes and vadose zone remediation. The project will result in a dramatic improvement of the predictive tools for traditional ground water management, irrigation and petroleum recovery applications. It has the strength to place Australia in the forefront of these technologies. Read moreRead less

Summary
Deep Earth Resource Characterisation and Extraction - An Integrated Geoscience Approach. Sustainability, economy and safety in resource recovery require a high level of understanding of the mechanics of geomaterials in their natural conditions and a multidisciplinary approach to the geotechnical issues involved. This initiative aims to bridge gaps between geotechnical disciplines, to combine the testing, analytical skills and experience of the research groups and to incorporate expertise and ide ....Deep Earth Resource Characterisation and Extraction - An Integrated Geoscience Approach. Sustainability, economy and safety in resource recovery require a high level of understanding of the mechanics of geomaterials in their natural conditions and a multidisciplinary approach to the geotechnical issues involved. This initiative aims to bridge gaps between geotechnical disciplines, to combine the testing, analytical skills and experience of the research groups and to incorporate expertise and ideas from the cognate disciplines of geology and geophysics so that innovative engineering practice will develop. This approach should achieve breakthroughs in understanding the behaviour of, and the safe economic extraction from deep resources including minerals, coal, gas drainage, petroleum and geothermal energy.Read moreRead less

Continuum Damage Mechanics in Geotechnical Engineering. Mining and oil exploration are amongst the major industries in Australia and must address geotechnical problems in which growth in damage plays a central role. For example, failure of an offshore platform can occur under cyclic environmental loading, due to accumulated damage to the seabed soils. Design tools are therefore needed that incorporate continuum damage mechanics in modelling the response of geomaterials. The project will place Au ....Continuum Damage Mechanics in Geotechnical Engineering. Mining and oil exploration are amongst the major industries in Australia and must address geotechnical problems in which growth in damage plays a central role. For example, failure of an offshore platform can occur under cyclic environmental loading, due to accumulated damage to the seabed soils. Design tools are therefore needed that incorporate continuum damage mechanics in modelling the response of geomaterials. The project will place Australia at the forefront in this field through the development of rigorous yet simple numerical models that achieve this, and thus underpin safe but economic geotechnical engineering solutions in the mineral resource industries.Read moreRead less
The micro-thermo-mechanics of sand crushing in geotechnical collapse problems. Oil and gas exploration is a major industry in Australia. Collapse problems in the soil to which structures such as oil rigs are anchored are a major challenge, involving issues of safety, longevity and maintenance. Research on this topic has been devoted to non-crushable sands, but Australia's offshore seabed is rich in breakable calcareous sediments. We will create a novel theory and visualisation techniques that wi ....The micro-thermo-mechanics of sand crushing in geotechnical collapse problems. Oil and gas exploration is a major industry in Australia. Collapse problems in the soil to which structures such as oil rigs are anchored are a major challenge, involving issues of safety, longevity and maintenance. Research on this topic has been devoted to non-crushable sands, but Australia's offshore seabed is rich in breakable calcareous sediments. We will create a novel theory and visualisation techniques that will allow us to gain a deep understanding of sand crushing and will be a major step towards minimising the occurrence of catastrophic failures in the offshore oil and gas industry.

This will directly benefit Australians. The development of the smart structure technology will also give domestic consultants the ability to compete internationally, resulting in obvious economic dividends and advantages benefiting Australia. Moreover, a successful effort leading to a major breakthrough of the important area of seismic protection research will have a significant impact far beyond the border of this country.Read moreRead less
Mechanisms of Ammonium Nitrate Decomposition and Stability of Industrial Explosives in Reactive Mining Grounds. This project is designed to probe reaction mechanisms of ammonium nitrate based explosives with pyritic shales commonly found in overburdens of mineral deposits, and to study the influence of various factors, such as mineralogical characteristics, carbonaceous materials, weathering, pH values and application of various inhibition agents, on the decomposition and stability of ammonium n ....Mechanisms of Ammonium Nitrate Decomposition and Stability of Industrial Explosives in Reactive Mining Grounds. This project is designed to probe reaction mechanisms of ammonium nitrate based explosives with pyritic shales commonly found in overburdens of mineral deposits, and to study the influence of various factors, such as mineralogical characteristics, carbonaceous materials, weathering, pH values and application of various inhibition agents, on the decomposition and stability of ammonium nitrate. Ammonium nitrate crystallisation, which significantly reduces the stability of emulsion explosives, will be examined using both chemical and microscopic tools. The outcomes of this research will provide a scientific basis that underpins the development of safe and cost-effective explosives for applications in dangerous reactive mining grounds.Read moreRead less

An innovative structural system utilising sandwich panel technology and shell action has recently emerged. These aesthetically pleasing curved structures are durable and spacious with fast construction time. They have residential and commercial applications and have attracted considerable local and overseas interest.
