Abstract
Cable bolts have been used in overseas mines for the past 25 years making effective use of the flexibility. The purpose of this report is to numerically examine the support effect of cable bolts installed in fractured rock mass. The numerical experiments were carried out so as to compare the support effect between cable bolts and rock anchors in terms of the presence of pretension. This report will especially describe how to construct the fracture network model based on the observed fracture characteristics and evaluate the bond characteristics of cable bolts from in situ pull-out tests.
