Introduction to Split Set Bolts
In the field of underground mining and tunnel construction, safety and efficiency largely depend on the anchoring systems used for rock and ground support. Among these systems, Split Set bolts have stood out as an innovative and effective solution, widely adopted by leading mining companies in Peru and worldwide.
What is a Split Set Bolt?
A Split Set bolt is a tubular steel anchor designed to provide immediate support in underground excavations. It consists of a longitudinally slotted tube that, when inserted into a drilled hole, expands against the rock walls, generating radial pressure and a friction effect that quickly and securely stabilizes the ground.
Advantages of Split Set Bolts
- Immediate support after installation
One of the most important benefits of Split Set bolts is that they provide instant support to the ground. This means that once installed, the rock or soil is stabilized immediately, minimizing the risk of falls or detachments during excavation. - Speed and ease of installation
Split Set bolts can be installed quickly and easily, without the need for additional materials such as resins or cement grout. This efficiency reduces downtime, speeds up project progress, and helps optimize resources in mining projects. - Adaptability to different geological conditions
Thanks to their flexible design and the variety of available lengths and diameters, Split Set bolts can be used in a wide range of terrains and geomechanical conditions, from hard rock to more fractured or weak zones. - Simple monitoring and maintenance
Split Set bolts allow visual inspection of their condition, facilitating periodic checks and preventive maintenance. They can also be easily complemented with plates, mesh, or other reinforcement systems for added protection. - Compatibility with other support systems
This type of anchor is fully compatible with other support elements such as welded mesh and shotcrete, enabling comprehensive support systems tailored to each project’s needs. - Proven durability and strength
Made from high-strength steel, Split Set bolts offer outstanding durability against the harsh conditions of underground mining, withstanding dynamic and static loads over time. - Reduction of operational costs
The combination of quick installation, immediate support, and less need for auxiliary materials contributes to significant reductions in operational costs in mining and underground construction projects.
Comparison with Other Anchoring Systems
Unlike other anchoring systems such as resin bolts, mechanical anchors, or cement-grouted bolts, Split Set bolts stand out for:
- Shorter waiting time for curing or hardening
- Fewer steps in the installation process
- Lower logistical and storage complexity
- Greater flexibility against unexpected geological variations
This translates into a safer work environment, lower accident risks, and higher productivity for underground operations.
