Technical Characteristics of the Expanding Bolt
Introduction: The Evolution of Mine Reinforcement
In the dynamic world of underground mining, the safety, efficiency, and sustainability of operations depend largely on mining support systems. The constant evolution of technology, geological challenges, and productivity needs have driven the development of innovations in mining support, allowing companies like FORMIN to offer customized solutions tailored to each project and type of terrain.
Why is it important to innovate in mining support?
Every mine is unique. Geomechanical conditions, rock types, tunnel depths, and seismic activity vary in each mining operation, making it essential to adopt flexible and personalized approaches to mine support. Innovating in support not only improves safety but also increases productivity and reduces costs, optimizing the lifespan of excavations.
Main innovations in mining support
1. New generation Split Set bolts
The evolution of Split Set bolts includes improvements in steel alloys, anti-corrosion treatments, and optimized designs for greater strength and ease of installation. Some models include integrated monitoring systems to measure applied load, allowing more precise real-time support control.
2. High-strength welded wire mesh
Next-generation meshes offer greater energy absorption capacity and flexibility, better adapting to ground movements and more efficiently protecting against falling rocks and fragments.
3. Custom modular formwork and systems
The use of modular metal formwork with custom designs allows adapting structural support to the specific dimensions and requirements of each gallery, tunnel, or drift, ensuring a perfect fit and faster installation.
4. Fiber-reinforced shotcrete with additives
The use of shotcrete with synthetic or metallic fibers and special additives has increased the strength, durability, and flexibility of sprayed concrete, making it a key ally for the support of tunnels and underground chambers.
5. Monitoring and digitization technologies
The incorporation of smart sensors and remote monitoring systems allows evaluating the state of support in real time and detecting movements or changes in the ground, facilitating a rapid response to potential risks.
6. Sustainable materials and ecological processes
Innovation in mining support also aims at sustainability, with the development of recyclable materials, low environmental impact processes, and technologies that minimize resource use and waste.
