Application of Water Based Fractionation in the Assessment of Metallurgical Coal. The metallurgical coal market (13% of coal market) is highly specialized, and competitive. The coal, which is utilized as a reducing agent in iron making, represents more than 52% of Australian coal exports. This study addresses growing evidence that organic liquids used to fractionate and in turn assess metallurgical coals lead to negative assessments, hence loss of markets, and lost opportunities.

The coal, which is utilized as a reducing agent in iron making, represents more than 52% of Australian coal exports. This study addresses growing evidence that organic liquids used to fractionate and in turn assess metallurgical coals lead to negative assessments, hence loss of markets, and lost opportunities. A new water based fractionation method will be established, and a systematic investigation into the effects of the organic liquids will be undertaken. These results will be used to build a case for replacing the organic liquids used in the industry, which are known to have negative health and environmental impacts. Read moreRead less

In situ microbial conversion of coal to methane: Biotechnology development for clean use of Australian coal. We will develop a biotechnology that uses native microorganisms to accelerate the underground conversion of coal to methane. Approximately 90% of Australia’s coal resources cannot be accessed economically using traditional mining technologies.

We will develop a biotechnology that uses native microorganisms to accelerate the underground conversion of coal to methane. Approximately 90% of Australia’s coal resources cannot be accessed economically using traditional mining technologies. A technology that converts coal to methane could generate an energy supply worth an estimated $60 billion, foster the development of an energy industry now in its infancy, and generate numerous new employment opportunities. Environmentally, methane is a cleaner burning fuel than coal, uses much less water for processing and generates the same quantity of electricity with lower CO2 emissions. This project highlights the fact that Australia’s microbial diversity is a resource we cannot afford to ignore.Read moreRead less
Model studies of the flow and thermal behaviour of non-spherical particles in fluid bed reactors. The Australian steel industry has a turnover of around $11 billion (5% of total manufacturing), being a largest manufacturing sector in Australia.

During heating, solid fuel particles undergo complex physical changes resulting in sophisticated structures in the residual material (coke and char) which influence the operational performance of these materials in ironmaking and power generation processes. The mechanistic understanding of the evolution of physical structure and the coupled role of gas evolution has not been well established. An interpretive and predictive mechanism to describe the process will be developed through experimental observations and mathematical modelling. The project will provide fundamental new insights and understanding of operational issues concerning the complex behaviour of solid fuel residues in coal based industrial processes.Read moreRead less
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
