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

Integrated processes for fine coal treatment. This project is concerned with new processes for the treatment of fine coal which forms an export market in excess of A$2 billion a year. The aim is to improve the separation of fine coal from silt and clay, and especially the recovery of larger particles in the flotation process. Further aims are to increase the ease of filtration and dewatering of fine coal, and to reduce the dust that is generated when fine coal is handled during transportation on ....Integrated processes for fine coal treatment. This project is concerned with new processes for the treatment of fine coal which forms an export market in excess of A$2 billion a year. The aim is to improve the separation of fine coal from silt and clay, and especially the recovery of larger particles in the flotation process. Further aims are to increase the ease of filtration and dewatering of fine coal, and to reduce the dust that is generated when fine coal is handled during transportation on land and sea. A laboratory-scale process will be developed and tested at a larger scale. The new knowledge that is gained will be essential for the successful introduction of the new technology into the Australian coal industry.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
