A Mohr-Coulomb material model was used for host rock to allow for plastic failure calculations. The conducted numerical study describes the role of dynamic stresses in blasting in a qualitative manner. On the other hand, a free face boundary was considered as a common blast operation which is conducted in surface mining.

Calibration of a numerical model for bore-and-fill mining by D. Roberts Bore-and-fill mining was implemented at a pilot site in Tau Tona mine's shaft pillar on 97 level. Observations, scan data, and measurements from this site were used to calibrate an inelastic numerical model of bore-and-fill mining within the Carbon Leader Reef (CLR).

The numerical modelling results also highlighted that fluids were being channelled through open fractures, resulting in preferred fluid-flow orientations following the overall fracture-network geometry (Fig. 10; Table 2). In addition, these numerical results indicated that the chosen aperture model has a great impact on the fracture-controlled
