en.Wedoany.com Reported - Swedish engineering group Sandvik Group announced on April 14, 2026, the addition of a fully integrated, end-to-end resin bolting solution to its underground ground support portfolio. This solution integrates Sandvik's underground drill rigs, pumpable resin systems, resin cartridge injection technology, chemical products, and bolt product portfolio, aiming to enhance the safety, quality, and productivity of global mining operations.
As a fully integrated engineered package, the solution ensures the coordinated operation of its components under various geological conditions. The single-supplier model improves installation efficiency and safety, and provides a ground support system validated by Sandvik's testing regime. Sandvik's resin bolting portfolio includes: a pumpable resin system for the DD422i/iE dual-control development drill rig, a pumpable resin system for the DS412i/iE and DS512i i-series rock bolting drill rigs, and an Automatic Resin Cartridge Injection System (ARI) for i-series bolting rigs. Among these, the DD422i is an intelligent development drill rig used for underground mine development and small cross-section tunnel driving; the DS512i is an automated rock bolting drill rig capable of installing bolts ranging from 1.5 meters to 6 meters in length.
The sealed pumpable resin system eliminates the need for manual handling of chemicals and is directly integrated into the equipment's control interface. Operators can safely complete the entire process from resin mixing and injection to curing from within the cabin, enhancing operational control and process consistency. The ARI system supports surface charging and automatic cartridge injection, allowing operators to perform other tasks while the system automatically inserts resin cartridges, reducing cycle times and minimizing personnel exposure to hazardous environments. Sandvik states that these technologies are redefining the standards for efficiency and safety in resin bolting operations.
The complete picture of the solution also includes various chemical products and bolt products. Mineral Bolt is a two-component urea-silicate resin, offering multiple formulations and adjustable curing times, enabling mines to match resin performance to ground conditions. Fasloc resin cartridges are available in multiple types and are produced in several locations worldwide. The DSI hollow bar system, along with solid rebar bolts and yielding bolts, further enhances the completeness of the solution, ensuring customers can match bolt types with resin technology.
Founded in 1862 and headquartered in Sandviken, Sweden, Sandvik's business spans mining machinery, metal cutting tools, materials technology, and other fields, employing approximately 50,000 people in over 130 countries and regions worldwide. The company stated that the new end-to-end resin bolting solution represents a significant advancement in modern automated ground support, providing the safety, reliability, and performance required in today's underground mining environments.
