In ground support, resin mixing quality isn’t a detail—it’s fundamental to rock bolt performance underground. Resin that isn’t properly mixed can compromise bolt encapsulation, reduce load transfer, and introduce variability into what should be a controlled installation process. The Sandvik Mining APAC Ground Support Posimix resin mixing system is engineered to actively and consistently mix the resin capsule during installation—helping deliver: 🔹 Uniform resin activation from toe to collar 🔹 More predictable bolt performance 🔹 Reduced installation variability 🔹 Greater confidence in ground support outcomes Thanks to the team at Creative Pipeline for helping me develop a short video to demonstrate how the Posimix mixing spring really works. The video is designed to highlight how the Posimix bolt mixes through the resin capsule, enabling the mastic and catalyst from the resin capsule to combine to create a homogenous cured resin bond along the length of the rock bolt. Whilst the Posimix bolting system has been around for many years, it still remains the one of the most effective mixing systems for resin bolting in underground mines. #Mining #GroundSupport #ResinBolting #SafetyInMining #Engineering #Sandvik
