Product Features & Applications
It overcomes the limitations of traditional rock bolts in strength, toughness, and durability, notably enhancing support performance in deep coal mining and complex conditions.
Cost advantages: While achieving ultra-high strength at the 700 MPa level, it significantly enhances the impact resistance and fatigue resistance of the bolt body. Compared with conventional equal‑strength rock bolts, it can reduce the bolt installation density by more than 30%, directly lowering the procurement cost of support materials. Meanwhile, the high ductility of the bolt body effectively prevents brittle fracture, greatly reducing the frequency of roadway repair and secondary support, thus cutting long‑term operation and maintenance costs. It also significantly shortens the construction period of roadway support and reduces the overall costs of labor and equipment rental.
