Self-Drilling Anchor Bolts
Different from ordinary anchor bolts, self-drilling anchor bolts are a main bolting solution for weak rock and unstable environment like the fracture zone and crustal deformation, especially when borehole caving-in occurs or extended anchor bolts are needed.
Maxdrill has developed its friction bolts which are mainly used as the simple and cost-effective form of ground support. Friction bolts have become available in mining and tunneling for decades.
