Understanding material behaviour under dynamic loading is essential in dealing with many engineering problems as excavation, fragmentation, earthquake, blasting, and structure design. In geotechnical and structure projects, materials are often subjected to existing confining stresses. The full-field optical techniques, with an ultra-high speed and resolution camera in the system, aims to assist the quantitative measurement of deformation fields including small strain induced in brittle material's failure and identification of constitutive parameters.Read moreRead less

This proposed project combines the expertise and disciplines of residential construction, structural dynamics and blasting technology. The ultimate aim of the project is to develop a rational methodology for assessing the damage potential of ground vibration resulting from blasting on typical Australian residential structures. The project involves field blast vibration measurements, static and dynamic laboratory tests on structural sub-assemblages in a controlled environment, and comprehensive analytical modelling of both loading and response. The outcomes from this research will have direct application to the mining, insurance, construction and defence industries.Read moreRead less
Development of a New Generation Low Rolling Resistance Conveyor Belt. Belt conveying systems are employed extensively to transport bulk materials within Australia's mining and mineral processing industries. The energy consumption of belt conveyors are significant and dominated by the indentation rolling resistance of the idler rolls into the bottom cover of the belt. This project will develop technology to design more energy efficient conveyors by employing new laminated low energy loss belt cov ....Development of a New Generation Low Rolling Resistance Conveyor Belt. Belt conveying systems are employed extensively to transport bulk materials within Australia's mining and mineral processing industries. The energy consumption of belt conveyors are significant and dominated by the indentation rolling resistance of the idler rolls into the bottom cover of the belt. This project will develop technology to design more energy efficient conveyors by employing new laminated low energy loss belt covers. With Australian mineral exports exceeding $100 billion, coupled with the considerable transportation distances often necessary in Australian mining operations, the outcomes of this research will result in significant energy savings and economic benefits to these vital industries.Read moreRead less
Modelling and Optimisation of Belt Conveyor Systems. Belt conveyors are the arteries of Australia's heavy industries. Their efficiency and cost are critical to the productivity of our major export markets. A current trend in this area is the introduction of high-speed and long distance conveying. This has placed tremendous pressure on the current design standards which are in drastic need of re-evaluation. This project will address these deficiencies and build a strong foundation for future conv ....Modelling and Optimisation of Belt Conveyor Systems. Belt conveyors are the arteries of Australia's heavy industries. Their efficiency and cost are critical to the productivity of our major export markets. A current trend in this area is the introduction of high-speed and long distance conveying. This has placed tremendous pressure on the current design standards which are in drastic need of re-evaluation. This project will address these deficiencies and build a strong foundation for future conveyor design. This will be achieved by developing rigorous mechanical models for conveyor mechanics and the application of state-of-the-art optimisation methods based on Darwinian natural selection. This will lead to significant improvements in the efficiency and running costs of belt conveyor systems.Read moreRead less

Belt conveyor systems are employed extensively to transport bulk materials in a great many industries, particularly those associated with mining and mineral processing. Belt conveyor installations are becoming longer and belt speeds significantly faster, resulting in increased dust emissions.

Belt conveyor systems are employed extensively to transport bulk materials in a great many industries, particularly those associated with mining and mineral processing. Belt conveyor installations are becoming longer and belt speeds significantly faster, resulting in increased dust emissions. An estimated 16 billion litres of water per annum is used by the Australian Black Coal Industry alone on dust suppression. This project will develop passive dust control technology, requiring no external energy or suppressants. This will be achieved through the development of numerical methods verified by rigorous experimental work. This will lead to significant cost savings, improved employee health and safety and reduced environmental impact.Read moreRead less

Despite the global financial crisis, the Australian Bureau of Agriculture and Resources Economics (Australian Commodities, December Quarter 2008) has forecast that earnings from Australia's energy and minerals exports will increase by 37% during 2008-09 to A$160 billion. Bulk materials handling operations constitute a major component of the minerals production and transportation costs. Through the research conducted in this project, greater efficiencies with reduced operating costs will be achieved while, at the same time, meeting the stringent environmental controls in accordance with the National priority goal of 'An Environmentally Sustainable Australia'.Read moreRead less
A new damage model for rock burst in hard rocks during deep mining. This project seeks to develop a new model to predict incipient rock burst in deep mines. Violent sudden energy released during dynamic brittle failure of rocks can kill people and cause serious damages to mining infrastructures.

This project seeks to develop a new model to predict incipient rock burst in deep mines. Violent sudden energy released during dynamic brittle failure of rocks can kill people and cause serious damages to mining infrastructures. The project aims to investigate formation of micro-fractures on the brittle shear zones during dynamic brittle failure of pristine rocks with a unique experimental methodology under high-pressure-temperature condition. It is anticipated that a new micromechanics-based damage model for brittle rocks will be developed from this. Implementation of the new coupled thermo-mechanical damage model into a finite element should result in realistic simulation of deep mining operations to identify rock-burst prone areas and allow mining managers to avoid potential hazards.Read moreRead less
