The aim of this project is to develop a robust optimisation technique for identifying geomechanical parameters for subsequent stability analysis of rock structures in particular open pits. The development involves a novel solution method based on current work in finite element method and large-scale optimisation with partial differential equation constraints. The outcomes of the project will provide a sophisticated numerical technique for geotechnical engineers/scientists to determine geomechanical parameters accurately from in-situ observation and displacement measurements, leading to the optimal design of rock structures in subsequent analysis.Read moreRead less
Excavation Design and Sequencing in Highly Stressed Rock Masses. An increasingly large number of Australian underground mines are being operated in highly stressed rock mass conditions, where safe and economic mining is a real challenge due to rock mass instability. In the future, this problem will become more significant as extraction gets deeper with the discoveries of new deeper orebodies or the extension of current operations at depth. The aim of this research project is to provide the Austr ....Excavation Design and Sequencing in Highly Stressed Rock Masses. An increasingly large number of Australian underground mines are being operated in highly stressed rock mass conditions, where safe and economic mining is a real challenge due to rock mass instability. In the future, this problem will become more significant as extraction gets deeper with the discoveries of new deeper orebodies or the extension of current operations at depth. The aim of this research project is to provide the Australian mining industry with effective design tools to engineer the largest, most economical, yet stable excavations in rock. The research project will use a generalised framework for design where rock mass characterisation, excavation design, behaviour and dilution control will be studied in detail.Read moreRead less
