Rock reimforcement bolt

Installing long-term rock bolts in poor rock conditions

One of the more difficult rock reinforcement tasks in underground mining and tunnelling operations is how to install long-term rock bolts in poor rock conditions. Rock bolting, as a result, is often the bottleneck within the drill and blast cycle, leading to difficulties to predict work task scheduling。Blocky or friable ground often leaves drilled bolt holes blocked or partially blocked. This slows down, or in the worst case, prevents the introduction of bonding agents such as cement grout or resin cartridges into the bolt hole.
