CABLE BOLTS
Cable Bolts for Underground Mining and Rock Reinforcement
Cable Bolts are high-strength reinforcement elements used to stabilize rock masses in underground mining, tunnelling and large underground excavations.
They are particularly suitable for applications requiring long reinforcement lengths and the stabilization of large or structurally controlled rock blocks.
What Are Cable Bolts?
Cable Bolts consist of high-strength steel cables installed into drilled boreholes and bonded to the surrounding rock using an appropriate grouting system.
Once installed and properly bonded, the cable transfers loads from potentially unstable rock structures into the surrounding rock mass.
Cable Bolts are particularly valuable in large excavations where longer reinforcement elements are required to improve structural stability.
Applications
Cable Bolts can be used in:
- Underground mining
- Stoping operations
- Large underground chambers
- Tunnelling
- Rock reinforcement
- Crown stabilization
- Hanging-wall stabilization
- Large-span excavations
- Fractured rock masses
- Underground infrastructure
Advantages
- Long reinforcement lengths
- High-strength reinforcement
- Suitable for large rock blocks
- Suitable for large underground excavations
- Adaptable to different underground geometries
- Suitable for demanding mining applications
- Can form part of systematic ground support systems
Installation and Performance
Cable Bolt performance depends on correct drilling, cable placement, grouting, encapsulation and installation procedures. Pull testing can be used to verify anchorage capacity and installation performance. SUCFOR provides on-site pull testing services for rock bolts and cable bolts, providing objective data for quality control and installation verification.
