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
Energy dissipation characterisation in dynamic brittle fracture. Energy dissipation in dynamic fracture of brittle materials is pivotal in mining, civil engineering and defence. The project aims to develop a novel experimentally-validated multiscale theory, with associated models, for characterising and predicting the complete dynamic fracture process of brittle materials. This theory is expected to generate close-to-reality simulations critical for understanding fundamental aspects of energy di ....Energy dissipation characterisation in dynamic brittle fracture. Energy dissipation in dynamic fracture of brittle materials is pivotal in mining, civil engineering and defence. The project aims to develop a novel experimentally-validated multiscale theory, with associated models, for characterising and predicting the complete dynamic fracture process of brittle materials. This theory is expected to generate close-to-reality simulations critical for understanding fundamental aspects of energy dissipation in dynamic fracture. The outcomes will enable an optimised control of the fragment size in block cave mining and mineral processing, forecast and prevent fatal rock bursts in underground mines, and minimise catastrophic failures in critical infrastructures challenged by extreme loading, e.g. explosions.Read moreRead less

Summary
ARC Training Centre for Integrated Operations for Complex Resources. This Training Centre aims to increase value in mining through clever applications of ‘lean processing’ and train the next generation of scientists and engineers in advanced sensors and data analytics in complex resources; knowledge priorities for the mining industry. Sensor information will be linked to the resource’s in-place knowledge to enable data analytics of all embedded knowledge.

This Training Centre aims to increase value in mining through clever applications of ‘lean processing’ and train the next generation of scientists and engineers in advanced sensors and data analytics in complex resources; knowledge priorities for the mining industry. Sensor information will be linked to the resource’s in-place knowledge to enable data analytics of all embedded knowledge. Processing can then be tuned to resource attributes, maximising value ‘on the fly’. Benefits will include increasing certainty on product quality and maximising throughput and recovery. Outcomes will include new tools to rapidly model geological and geometallurgical uncertainty with sensor inputs, to track the resource to product and enhance interpretation.Read moreRead less
