Project Overview

As Resolution Copper Mining (RCM) constructed the No. 10 Shaft, they encountered a unique condition over 7,000 feet underground. The air temperature exceeded MSHA safety standards for human occupation.  RCM had to move fast to provide a solution to cool the underground mine so that the team could continue the underground construction.  To meet the schedule and budget, RCM developed a plan for a fast track design-bid-build project. They needed a proven industrial contractor to take on the risks and complications of the schedule. Sundt was chosen to be the contractor to construct a state-of-the-art high-performance refrigeration system to meet the challenges of a 7,000-foot-deep shaft with rock temperatures reaching 170 degrees.

The project included installing three York refrigeration chillers, three banks of condensed cooling towers, 2,000 linear feet of four-part insulated 28-inch Victaulic pipeline, a full glycol cooling system and tank farm, a 72-inch bulk air cooling fan, a concrete portal shroud, four 750 horsepower in line cooling pumps, a complete upgrade to the electrical distribution system, and a complex instrumentation and controls system to run the plant. The work was completed on an active mining site without interrupting any mine site activities.

“What sets Sundt apart from their competition is that they are better at relationships with the owner than their competition.”
