Solving the pumpable resin riddle, a new automated resin system should improve safety for hard-rock miners working in difficult geology

It’s no secret. Today’s miners are pursuing metals in deeper underground operations. In the western U.S., gold miners are encountering weak geological conditions. In Canada, some of the mines are so deep that the geology is becoming fluid. While the fluid description might be an exaggeration, what was needed in both cases was a rock bolting solution.

If the miners are going to win the battle in these extreme conditions, they will have to add some new tools to their arsenal. One of the leading ground control suppliers, Jennmar, has recently announced three big developments: the self-drilling, yieldable Multiple Point Anchor (MPA) bolt, an improved inflatable bolt with a corrosion-resistant coating, and a pumpable resin injection system, J-Lok P.
