Rock bolting systems are used to stabilize excavated rock mass in underground mines and tunnelling. Rock bolts are systematically arranged to transfer the load from the unstable surface or exterior of the rock, to the much stronger interior part of the rock. The rock mass can be reinforced by different types of rock bolts.

As an efficient placing approach, self drilling rock bolt palys a significant role in supporting rock mass to prevent deformation and excavation,buildings,roadway,bridges,large equipment are all established on the rock, so the stabilization of rock layer will be extremely important. Self drilling rock bolt system is widely used in foundation reinforcement projects, such as railway, tunnel, mining, hydropower station, dam, bridge base, water bank, high building foundation etc., also widely applied in solving geological disaster, such as foundation subsidence, hole collapse, break, collapse, and landslip etc.
