Fiscor discusses the potential impact of the new automated resin system developed by ground control supplier Jennmar to solve the pumpable resin and to improve safety for hard-rock miners working in difficult geologic conditions. The Jennmar's big developments include the self-drilling, yieldable Multiple Point Anchor (MPA) bolt, an improved inflatable bolt with a corrosion-resistant coating, and a pumpable resin in injection system. To develop this system, a major hurdle had to be cleared and a special manifold that allows the pump to push resin through a two-line system into the hole using an injection nozzle. Also noted the alternative rock bolting technologies such as a self-drilling, one-pass bolt that would yield and push the coarse threads on each end and on how to implement the system.
