Goals

Numerical modelling rock breakage and granular flow on all scales relevant to the minerals Industry, to provide the fundamental underpinning for development of frontier mass-mining and sustainable minerals processing operations.

Virtual Rock Laboratory

Global demands for minerals resources are driving the minerals Industry to develop underground mass-mining operations at greater depths and increasingly challenging geotechnical environments for which traditional mining methods would be unsuitable, unsafe or uneconomical. Key to the success of current and planned mass-mining operations is characterising rock mass response and fragmentation induced by caving operations. High performance numerical modelling is considered the way of the future for quantitative prediction of rock mass response and operational design decisions. Downstream, minerals processing operations are experiencing increasing pressure to reduce the energy consumed in comminution (the fragmentation of ore into powder suitable for processing). The AuScope S.A.M. and AuScope Interoperability components are building a Virtual Rock Laboratory to support fundamental research on rock mass response and fragmentation on all scales relevant to the minerals Industry. Leveraging world-class supercomputing hardware and the ESyS-Particle discrete element software, the Virtual Rock Laboratory provides a simple, intuitive framework for Computational Engineering Analysis involving large deformations (granular media flow) and fragmentation.
