Large-scale panel destressing is a rockburst control technique that is used to create a stress shadow in the ore pillar to be mined. The technique aims to reduce the pillar burst proneness by deviating the major induced principal stresses away from t

Destress blasting is a rockburst control technique where highly stressed rock is blasted to reduce the local stress and stiffness of the rock, thereby reducing its burst proneness. The technique is commonly practiced in deep hard rock mines in burst

To elucidate the mechanism of seismic activity taking place away from extracted stopes in underground mines, this study focuses on the influence of a fracture network on the intensity of seismic activity from an energy point of view. Four seismically

Seismic moment is a predominantly utilized parameter for assessing fault-slip potential when the numerical modelling of fault-slip is carried out. However, relying on seismic moment as an indicator for fault-slip might lead to incorrect conclusions,

Rockbursts in underground mines can cause devastating damage to mine workings; hence, it is important to be able to assess the potential for their occurrence. The present study focuses on a large seismic event that took place at an underground base m

There is variability in the geometry of the ore outline, particularly between the footwall (FW) and hanging wall (HW), across the strike length of the various orebodies at Copper Cliff Mine. This geometry creates a requirement to plan transverse sill

The assessment of the performance of ground support systems under dynamic loading is typically subjected to qualitative and subjective interpretations. As a result, it is difficult to develop an explicit knowledge of the mechanisms of action and inte

Mining in the 100/900 orebodies (OB) at Copper Cliff Mine in the Sudbury Basin has been associated with significant seismic activity. In September 2008, a 3.8 magnitude event occurred in the middle 100/900 OB and caused considerable damage to various
