self drilling rock bolt

rock bolt are used for rock bolting and grouting in softer rocks, especially the loose ground and sections prone to collapse. rock bolt stabilises the slopes which are highly weathered or broken. rock bolt can also be used for rock pinning and rock dowel applications where localized reinforcing of the rock face is required. rock bolts are typically regarded as lightly loaded, full bonded installations, for low risk applications.

Stabilisation of tunneling
rock bolt is usually used in mining, hydroelectric, and tunneling projects.
Sinorock rock bolt is used extensively for the stabilization of tunnel portals. The ability of rock bolt accommodate a range of different ground conditions make them a popular choice for tunneling works. Spiles are used to form a protective canopy for tunneling in areas of loose ground. When rock bolt is used as spiles, the bolt can be drilled into place using rotary percussion and then grouted through the hollow core to consolidate the heading.

rock bolt can also be used in mining applications. In mining applications, rock bolt is used for the bolting of pillars, the injections of resins or waterproofing agents as well as for general reinforcement applications.
