All threaded self-drilling rock bolt system

[henry007 0]

The self-drilling rock bolt system is comprised of a hollow threaded bar with an attached drill bit and a series of accessories that can perform drilling, anchoring and grouting in a single operation. Since its introduction 30 years ago the expandable rock bolting system has gained wide recognition in the mining and tunneling industry. The unique rock bolt is re-expanded using a high pressure water flow provided by a special pump and adapter. The bolt is expanded inside the borehole. The installation process is easy and very similar, making the rock bolts accessible to almost all operators. Self-drilling rock bolting is used to stabilize excavated rock mass in underground mines and tunneling. 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.
