Numerical Modeling Methodology for Weak Rock Masses in Nevada gold mines
… for excavation span and support design. MPBX arrays were installed in underground excavations and the displacements at MPBX nodes were observed for previous numerical model calibration. Time dependent numerical models were designed to take into consideration the effect of jointing using …

Investigation of the Pre to Post Peak Strength State and Behaviour of Confined Rock Masses Using Mine Induced Microseismicity
As hard rock mining progresses into higher stress mining conditions through either late stage extraction or mining at depth, the rock mass is driven not just to the peak strength, but often well into the post-peak until complete ‘failure’ occurs and easier mining conditions become evident. Limited …
