Abstract Pumpable, two-component resins for anchoring rock bolts provides significant advantages over traditional cartridge resin and cement grout systems where fast and easily adaptable support is required for difficult ground conditions.

Cartridge resin anchoring with rock bolts is often ineffective in oversized, fractured and washed-out holes. Cement grouting of cable bolts is frequently plagued with quality assurance and quality control issues related to the grouting process. Installation of cable bolts with resin injection techniques is routinely completed, in-cycle, allowing blasting immediately after bolting.

Xstrata Nickel has evaluated the Minova Resin Injection System since 2007. The Nickel Rim Mine and partner Minova have tested and validated the Resin Injection process for bolting procedures including Hollow Fiberglass Bolts, Rebar, Modified Cone Bolts and Cable Bolts. The resin injection process is adaptable to most bolting processes and equipment. Currently, Nickel Rim Mine use two types of resin injection products with different set times to grout deep cable bolts and development support in highly variable ground conditions. The product consistency, predictability and adaptability in application along with a high crew acceptance continue to make this support process part of an adaptable ground support system in highly variable ground conditions.
