Phase 1: Crusher assembly
The first phase took us underground to the crusher assembly at the Gordonsville site, where we performed a complete re-skin using AR-500 wear plate. Years of rock impact had thinned critical areas around the chutes and grizzly bars, so every plate was custom-cut, mitered, and fit to reinforce the weak spots. These new skins were designed to extend service life until permanent replacements were fabricated.
Phase 2: New chutes
The second phase moved topside for the Room-and-Pillar shaft supports and the fabrication of new chutes to replace aging ones. This phase involved heavy-gauge steel components and precise fit-up to ensure long-term performance. Even while managing equipment repairs for the mine during this phase, our two-man crew out-produced larger teams—delivering early and to spec.
Phase 3: Chute repairs & heavy equipment
The final phase brought us to Nyrstar’s Cumberland Mine, where we performed critical repairs on a butterfly/separator chute for the conveyor system. We stabilized and reinforced the existing chute to keep production running until a new one could be installed—another on-time solution that kept operations moving without disruption.
