Axisymmetric triaxial compression loading–unloading tests are conducted on twenty-seven marble specimens with initial confining pressures of 20, 30 and 40MPa and unloading rates of 0.1, 1.0 and 10MPa/s. It is found that magnitude of initial confining pressure and unloading rate significantly influence rock failure modes and strain energy conversion (accumulation, dissipation and release) during unloading...
A model of the Ventersdorp Contact Reef (VCR) orebody at Kloof Gold Mine was derived by integrating 3D reflection seismic data with information derived from underground mine mapping and exploration drilling. The study incorporated the depth-converted prestack time migrated (PSTM) seismic cube, the mine geomodel, faults and dikes mapped in excavations, mine development infrastructure, and intersections...
Fault slip bursts induced by mining activities could inflict severe damage to nearby mine developments. Considering a variety of factors that might exert an influence on the fault slip, dynamic numerical analyses are conducted for models having a fault parallel to a tabular ore deposit. The results obtained from the analyses show that the maximum dynamic shear displacement increment induced by stope...
