Fabric-guided micro-fracturing phenomenon in brittle rock and its effect on crack damage thresholds remains a subject that challenges researchers. Anisotropy...
Compression and micro-fracking hydraulic tests were carried out at the CanmetMINING Rock Mechanics Laboratory in Ottawa, Ontario, to determine the mechanical...
Brittle spalling is the failure mechanism that is commonly observed in the walls of underground excavations in rocks with high ratio of compressive to tensile...
The crack damage progression in crystalline rocks is approximated in laboratory by means of rigorous strain measurement and/or monitoring of Acoustic Emission...
Trials were undertaken in a narrow-vein mine of Northern Quebec, Canada, to monitor stress changes in sill pillars due to mining. Trials were carried out in...
The prediction of failure conditions has always been a critical issue in rock engineering. One of the factors that makes this a complex problem is the...
In 2005, Dyno Nobel Canada Inc, DynoConsult and CANMET-MMSL used their pool of expertise in blasting, ground control, open pit and underground mining, mineral...
