Mechanical Characterisation of Modified Cable Bolts Under Axial Loading: An Extensive Parametric Study

A wide range of modified cable bolts are currently used for ground support in different conditions in Australian underground coal mining operations. This is mainly based on the belief that the performance of modified cable bolts is better than conventional cable bolts. Despite this positive view, very few studies have characterised the performance of modified cable bolts in service. A new laboratory-based pull-out testing facility was employed...
