In the demanding environment of underground coal mining, roof stability is paramount. The synergy between resin anchoring agents and rock bolts forms the first line of defense against roof falls and ground instability. ZHONGFU provides high-performance solutions in both categories, engineered to work seamlessly together and create a secure working environment.
Resin cartridges are the crucial component that activates the support system. ZHONGFU's fast-setting and full-column resin grouts are designed for rapid curing and high bond strength. Upon installation, the bolt ruptures the cartridge, mixing the resin and hardener to form a solid, high-strength grout that instantly locks the bolt into the borehole. This process creates a rigid connection that distributes load effectively into the rock mass.
ZHONGFU's range of rock bolts, including high-tensile rebar and specialty bolts, are the structural elements of this system. When combined with our resins, they transform a simple borehole into a reinforced structural member. The resin-to-bolt bond ensures full-column load transfer, preventing progressive failure and creating a stable, reinforced zone in the immediate roof.
The application process is efficient: drill the hole, insert the resin cartridge, and install the bolt using a roof bolter. The rapid setting of ZHONGFU resins allows for immediate tensioning, providing critical support right after installation. This integrated system is vital for securing development headings, longwall gate roads, and other high-stress areas.
