With technology rapidly advancing to meet evolving operational challenges, engineers do not often look backward for solutions. However, in examining options for supplying cooling and compressed air for ultra-deep mines, engineers may have found the answer in a technology that is more than 100 years old.
Soon, test results will reveal if resurrecting and refining Hydraulic Air Compressor (HAC) technology holds the key for affordable, resource-conscious cooling.
