The project aimed to develop a high resolution model to simulate the evolution of stress, strain and energy release between different structural and geotechnical domains in a complex mine geometry. The sufficiency requirement for the model was to match the measured seismicity well enough that the tool could be used to quantitatively differentiate potential levels […]

At the time of writing, the maturing Grasberg Block Cave (GBC) is producing an average of 14,500 tpd from three active mining fronts. The mine is currently comprised of approximately 250 km of development with 42,000 m2 of established undercut from two production blocks beneath the Grasberg open pit. The pit to underground transition is

Sublevel shrinkage (SLS) is a mining method primarily suited to thick, steeply-dipping or vertical orebodies within a strong and competent host rock of low caveability. Although relatively infrequently utilised, the SLS technique has been applied in Australia in the past (Mackay et al. 2014). SLS is also currently being implemented at a small number of

In late 2021, the potential to extend a very large open pit was investigated. The mine has a high-resolution structural and hydrogeological model, permitting construction of a large-strain, discontinuum, closely coupled hydromechanical finite element model with a much better than inter-ramp scale representative elementary volume. In models of this type, the hydrogeological parameters and constitutive

Emphases on displacement-based ground support design are increasing as more accurate and reliable ground deformation monitoring systems become available in mining operations (Lowther et al. 2022; Kaiser & Moss 2022). The key principle behind displacement-based design is to allow controlled deformation or displacement of the surrounding rock, ensuring that it remains within acceptable limits to

Mining within deep and high-stress conditions inherently involves risks both to the personnel and the mining operation. To operate safely and efficiently in such extreme environments, it is necessary to understand the behaviour of the rock mass in response to the continuously changing stress field. Mobile scanning data acquisition methods and interpretations have emerged since
