Optimization of Cable Bolting Installation for the HW of an Open Stope
Cable bolting the HW of relatively shallow dipping open stopes is a common practice for the support of underground openings. This helps control dilution (thus reducing cost) and increases stopes turnover. The purpose of this example is to demonstrate the effect of cable bolting on the stability of an open stope’s hanging-wall (HW) in a blocky ground and how to improve a given cable bolting pattern.
Behavior of a Shear Zone (fault) Adjacent to UG Mining Excavations and its Implication on Mine Planning
Most of underground or open pit mines have geological discontinuities including major faults and shear zones that could impact the mining sequence, recovery and ground control designs. This example shows that fault-slip analysis is sensitive to the orientation and magnitude of far field stresses, as well as the geometry and the geotechnical properties of the shear zone.
