<p>A numerical assessment of historical, caving induced subsidence at the Kiirunavaara Lake Orebody has been conducted. Established displacement and strain-based criteria have been used to accurately simulate the evolution of ground surface displacements during ...
Since 2001, the Hybrid Stress Blast Model (HSBM) project members have developed a software suite to model the complete blasting process from non-ideal detonation to muck pile formation. To preserve the physics and improve solution time, the breakage engine ...

This research project focuses on the application of numerical modelling methods to rock mechanics problems, combining theoretical, experimental and numerical modelling work. Specifically, practical finite difference modelling approach for analysing shaft lining ...
The accurate assessment of cave initiation and propagation is of critical importance to the planning of any new caving operation. For this reason, the use of numerical models for simulation of the undercutting, draw, propagation and surface subsidence processes ...

Two movements of particular interest are the creation of gaps above coal pillars and falling of standing support elements without apparent damage. A dynamic boundary element program was used to explore movements induced by slip on geologic features removed ...

A coupled hydromechanic analysis predicts a significant pore pressure drop due to the volumetric expansion associated with the excavation of the pit. This lower pore pressure distribution allows for a more aggressive and economical slope design.
