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
Minimization of emissions from dimethyl ether (DME) combustion in a diesel engine. The project works on the utilization of dimethyl ether, an innovative clean fuel produced from coal or natural gas, as a diesel substitute. The utilization of DME in diesel engines can potentially reduce the emissions by 90%, making it possible to meet the strictest engine standard. In the meantime the engine efficiency can be improved. The outcomes of the project will help accelarate the maturity of the DME mark ....Minimization of emissions from dimethyl ether (DME) combustion in a diesel engine.

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. 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-tempera ....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. 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

This project aims to selectively extract base and precious metals from their ores in saline and non-saline environments, building upon a patented process utilising edible glycine under oxidising and mildly alkaline solutions. Extraction processes of metals from primary resources mostly use harsh, toxic and/or non-recyclable reagents. Exploratory research has already indicated the potential for easy metal recovery from their alkaline glycinate solutions and recycling of the lixiviant (glycine). Anticipated outcomes are a safe, non-toxic process for extracting metals from primary resources.Read moreRead less

The work is of high importance since failure of cable bolts is now being reported in several mines across Australia and is expected to become a problem world-wide. The work is novel as it intends to be the very first study of catastrophic cable bolt failure. The expected outcome is the development of economically viable solutions for avoiding catastrophic cable bolt failure. It is anticipated that the findings will also be relevant to the civil engineering sector.Read moreRead less
Controlling density, viscosity and crystallisation in emulsion explosives to enhance safety and efficiency of blasting operations. The performance of emulsion explosives used throughout the mining industry can be severely compromised by the effects of shear arising from pumping and detonation shock waves. Understanding how shear affects droplet coalescence and crystallisation is critical in differential energy blasting, where emulsion density and composition vary widely along the bore hole.

The performance of emulsion explosives used throughout the mining industry can be severely compromised by the effects of shear arising from pumping and detonation shock waves. Understanding how shear affects droplet coalescence and crystallisation is critical in differential energy blasting, where emulsion density and composition vary widely along the bore hole. This project aims to contribute to the understanding of the effects of shear, and develop new methods and additives to stabilise droplets and bubbles over a wide range of compositions and conditions. The goal of this project is to improve the efficiency and safety of rock-blasting operations, reduce environmental impact, and reduce operating costs, giving the Australian mining industry a competitive edge.Read moreRead less

This project represents a major advance in the problem of optimising the mine value associated with the access infrastructure of underground mines and providing powerful planning tools for management. The usefulness to the mining industry of the methods and algorithms the project is pioneering lies in their accuracy, flexibility and generality. Not only can they be used for benchmarking value in the design of specific mines, but they can also determine the profitability or viability of mines under the use of new technologies. This is an important project for ensuring that Australia's mining industry remains efficient and internationally competitive. Given Australia’s economic dependence on mineral resources, it will also benefit the country as a whole.Read moreRead less
Presumed Guilty: An Economics Analysis of the Efficiency of Environmental Bonds for the WA Mining Sector. Environmental bonds have two important economic effects. First they give an incentive for mining firms to manage environmental damage and second they prevent excessive costs falling on the regulator in the case of bankruptcy. The aim of this project is to assess if this policy can be redesigned to increase its economic efficiency.
