Gassing Mechanism and Stability of Foamed Explosive Emulsions. Mining of minerals such as coal involves crushing the surrounding rock strata, or the mineral ore itself, with emulsion explosives. One of the most important properties determining suitability of an emulsion explosive to a particular mining operation is its velocity of detonation, which can be adjusted by varying the number and size of air bubbles distributed in the emulsion matrix. The present project aims to develop new ways of g ....Gassing Mechanism and Stability of Foamed Explosive Emulsions. Mining of minerals such as coal involves crushing the surrounding rock strata, or the mineral ore itself, with emulsion explosives. One of the most important properties determining suitability of an emulsion explosive to a particular mining operation is its velocity of detonation, which can be adjusted by varying the number and size of air bubbles distributed in the emulsion matrix. The present project aims to develop new ways of generating air bubbles, to gain fundamental understanding of the foaming mechanism in currently used gassing techniques, and to invent ways to stabilise large bubbles within the emulsion. The project will provide scientific underpinning for the development of a new range of emulsion explosives manufactured by Orica for Australian and international markets, maintaining the Orica's position as a leader in the field of emulsion explosives.Read moreRead less

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
Role of Reactive Particles in Explosive Emulsions. Concentrated water-in oil explosive emulsions are widely used in the minerals industry because they are cheap, easily detonated and relatively safe to handle. Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and ch ....Role of Reactive Particles in Explosive Emulsions. Concentrated water-in oil explosive emulsions are widely used in the minerals industry because they are cheap, easily detonated and relatively safe to handle. Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and chemical interactions that occur between the particle and the oil-water interface, and develop a more efficient explosive that can be produced continuously on a commercial scale.Read moreRead less
High Strength Steel Protection Bollards. Terrorist attacks cost Australians much human grief and millions of dollars. Prevention of an attack is paramount. Passive road bollards are commonly used to stop a vehicle approaching and/or entering security sensitive infrastructure. Thin-walled tubes are used to manufacture such bollards. However there is a lack of knowledge about their behaviour, and in particular high strength alloy steel bollards, when subjected to impact loads.

Passive road bollards are commonly used to stop a vehicle approaching and/or entering security sensitive infrastructure. Thin-walled tubes are used to manufacture such bollards. However there is a lack of knowledge about their behaviour, and in particular high strength alloy steel bollards, when subjected to impact loads. The investigators will apply their extensive knowledge in thin-walled tubular structures to establish the most economical means of designing high strength bollards. This knowledge will be transferred into design standards and Australia's limited defence resources.Read moreRead less

Around 50% of congestive heart failure sufferers have some form of sleep disordered breathing. However, little has been done so far to simultaneously monitor, analyse and treat the two conditions. Therefore, this project proposes to develop new technology incorporating mathematical models for heart rate variability, considering the links between sleep disordered breathing and cardiovascular disease. This innovation will enable, for the first time, a device capable of accurate and reliable diagnosis of various sleep disorders using only conventional ECG data. Such technology has the potential to produce significant community health benefits, and save several millions of lives worldwide.Read moreRead less
