EXPANDABLE BOLTS
Expandable Bolts for Underground Mining and Tunnelling
Expandable Bolts are mechanical rock reinforcement systems designed to provide
reliable ground support in underground mining, tunnelling and underground
infrastructure projects.
SUCFOR Expandable Bolts are designed for applications where effective rock
reinforcement, controlled load transfer and efficient installation are essential.
Their mechanical expansion creates contact with the surrounding rock along the
anchorage zone, providing a practical solution for reinforcing underground
excavations.
How Expandable Bolts Work
Expandable Bolts are installed inside a drilled borehole and mechanically
expanded against the surrounding rock. The expansion creates friction and contact
between the bolt and the borehole wall, allowing loads to be transferred between
the rock mass and the reinforcement.
This principle makes expandable rock bolts suitable for a variety of underground
conditions, including fractured and variable rock masses where efficient
mechanical anchorage is required.
Applications
Expandable Bolts can be used for:
- Underground mining
- Mining drifts and development headings
- Tunnelling
- Highway and railway tunnels
- Underground infrastructure
- Galleries and hydraulic infrastructure
- Rock reinforcement
- Ground stabilization
- Temporary and permanent ground support systems
Advantages
- Mechanical anchorage
- Efficient installation
- Suitable for fractured rock
- Immediate mechanical interaction with the surrounding rock
- Suitable for systematic rock reinforcement
- Compatible with rock support plates and other ground support components
- Suitable for demanding underground environments
Expandable Bolts can form part of a complete ground support system together
with plates, mesh, shotcrete and other reinforcement technologies.
The appropriate bolt type, length, installation pattern and support configuration
should always be determined according to the geological conditions, excavation
geometry and geotechnical design.
SUCFOR supplies technical ground support solutions for mining, tunnelling and
underground construction projects.
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
How Split Set Bolts Work
- 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.
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

- 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

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.
REBAR BOLTS
Rebar Rock Bolts for Ground Reinforcement
Rebar Bolts are steel reinforcement bars used to stabilize rock masses in
underground mining, tunnelling, civil engineering and underground infrastructure
projects.
They provide a versatile solution for transferring loads between the surrounding
rock mass and the reinforcement and can be used in both systematic and
localized rock reinforcement applications.
How Rebar Bolts Work
Rebar Bolts are installed into drilled boreholes and bonded to the surrounding rock
using suitable anchoring materials such as cementitious grout or resin systems.
Once bonded, the reinforcement helps control movement and transfer loads from
potentially unstable areas of the rock mass into the surrounding ground.
Applications
Rebar Bolts are used for:
- Underground mining
- Tunnelling
- Mining galleries
- Underground infrastructure
- Rock reinforcement
- Ground stabilization
- Roof and wall reinforcement

support products to create integrated rock reinforcement systems.
SELF-DRILLING ANCHORS
Self-Drilling Anchors for Ground Stabilization
Self-Drilling Anchors are ground reinforcement systems designed for applications
where conventional drilling and anchoring methods may be difficult to install.
They are particularly useful in weak, fractured or unstable ground, where borehole
collapse can make conventional anchor installation challenging.
How Self-Drilling Anchors Work
A Self-Drilling Anchor uses a hollow steel bar that acts both as a drilling rod and as
the permanent reinforcement element.
The drill bit creates the borehole while the hollow bar remains installed in the
ground. Grout can then be injected through the hollow bar, filling the space around
the anchor and creating the bond between the reinforcement and the surrounding
ground.
This drilling-and-anchoring principle can simplify installation in difficult geological
conditions.
Applications
Self-Drilling Anchors are suitable for:
- Weak rock
- Fractured rock
- Loose ground
- Underground mining
- Tunnelling
- Ground stabilization
- Slope stabilization
- Geotechnical works
- Temporary reinforcement
- Permanent reinforcement
- Difficult drilling conditions
Advantages
- Drilling and reinforcement in one system
- Suitable for unstable ground
- Suitable where boreholes may collapse
- Grout injection through the hollow bar
- Efficient installation in difficult geological conditions
- Suitable for mining, tunnelling and geotechnical applications
Self-Drilling Anchors can provide an effective solution where conventional drilling,
hole cleaning and subsequent reinforcement installation are difficult to control.
