Mining Rock prestress Anchor Bolts

Brief introduction

Self drilling rock anchor bolt is a bolting solution for unstable ground conditions such as sand, gravel, silt, and clays, and in soft to medium fractured rock formations.

For projects facing above geo-conditions, hollow bar self-drilling anchor should be considered as the main solution cuz it's designed for optimized installation, tailored to the project's needs.

By drilling a hole in collapsing soil or loose lock, with a sacrificial drill bit an a hollow bar, and after the drilling operation injecting cementitious grout or resin into the hollow bar and surrounding cavity, it's a top solution choice.
