HX-Bolt - Hollow hybrid dynamic bolt
Overview
HX‑Bolt is a hybrid dynamic rock bolt designed to deliver instant, high-performance ground support in weak, fractured, and high-stress underground conditions.
By combining mechanical anchorage with full-length frictional confinement, HX‑Bolt provides immediate load-bearing capacity and controlled energy absorption—ensuring stability in dynamic environments. The system is engineered for rapid installation using standard bolting equipment, helping improve safety, development speed, and operational efficiency.
With the option for post-installation grout injection, HX‑Bolt can also be adapted for enhaned anchorage, long-term reinforcement and corrosion resistance, making it suitable for both temporary and permanent support applications. The integrated friction anchor helps retain grout or resin within the borehole, reducing losses into fractures and voids while improving encapsulation effectiveness in weak and broken ground.
Delivers instant high performance ground support, that continues to perform long-term
