Overview

DSI Fibreglass Cuttable OneStep self-drilling bolt has revolutionised rock bolting. It integrates the currently-used bolt installation components into one self-contained product, providing a robust system for fast, easy, safe, and reliable ground control.

The Fibreglass Cuttable OneStep rock bolt system consists of three major components: the drilling system, the resin encapsulation system, and the dispensing pressure system.
The inherent safety and technical benefits have made OneStep bolts a logical choice for hazardous mining scenarios such as longwall shield recovery, as well as difficult development conditions where drill hole collapse is common.
The inherent productivity benefits are yet to be fully realised, but offer great potential for current mining systems, and especially in the path to automation.
