Roof Rebar Rock Bolts Mining Bolting Industry Rock Bolt Self Drilling Tunnel Full Threaded Mine Steel Bar Forged Hollow Grouting Anchor RodAnchor Tool Self Drilling Anchor Bolt Threraded Bar Anchor Rods Introduction

Concrete Anchor Bolts for Coal Mining 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.
