Rock bolt 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. Sinorock offers different types of rock bolt system,including self drilling rock bolt,Expansion Shell Rock Bolt,ect.

Due to special mechanical characteristics (i.e. very high elongation, very high ductility) Rock Bolts are essentially used in mining applications.Other geotechnical applications for Rock Bolts are stabilization of soil masses under load, cavern/tunnel walls, excavations or slopes.Other advantages are high loads which can be carried with small borehole diameters and high shear bonding between deformed bar and cement grout.
