Introduction

Rockbolting, which is widely used in geotechnical and mining engineering, is a reinforcement technique to stabilize rock masses through high-strength members such as cablebolts, rebars and steel pipes (Graham 1996). Rock reinforcement improves the load-bearing capacity of rock masses by increasing the strength of the rock masses (Hoek and Brown 1980).

Rockbolts can be divided into three types based on the anchorage mechanism—mechanical bolts, bonded bolts and friction bolts (Hoek et al. 2000). Mechanical bolts are normally used as temporary supports because of its immediate support ability and low cost. The disadvantages of mechanical bolts include strict requirement for borehole drilling and high dependence of the mechanical grip on borehole diameter (Cai and Champaigne 2012).

The strengthening effect of bonded bolts depends on the adhesion of bonding materials grouted into the space between the rockbolt and the borehole wall. Bonded rockbolts include epoxy resin...
