SPLIT SET
Split Set Rock Bolts for Mining and Tunnelling
Split Set rock bolts are friction-based rock reinforcement systems widely used for underground mining, tunnelling and ground stabilization.
Their simple construction and efficient installation make Split Sets a practical solution for systematic reinforcement of underground excavations, particularly where fast mechanical rock support is required.
How Split Set Bolts Work
A Split Set consists of a slotted steel tube installed into a drilled borehole.
During installation, the steel tube is forced into the borehole. The resulting radial pressure creates friction between the tube and the surrounding rock. This friction provides anchorage along the length of the reinforcement and enables load transfer between the rock mass and the bolt.
Applications
Split Set rock bolts are suitable for:
- Underground mining
- Mine development
- Tunnelling
- Underground infrastructure
- Rock reinforcement
- Ground stabilization
- Roof and wall support
- Fractured rock formations
- Systematic ground support
Advantages
- Fast installation
- Simple mechanical design
- Friction-based anchorage
- Efficient systematic reinforcement
- Suitable for underground mining and tunnelling
- Compatible with plates and mesh
- Suitable for a wide range of underground support applications
Split Sets can be integrated into complete rock support systems with bearing plates, mesh, shotcrete and other ground reinforcement products.
Correct selection and installation should be based on the rock mass characteristics, excavation geometry, expected ground behaviour and project- specific geotechnical requirements.
