Numerous instances of the word "efficiency" in fan system evaluation contribute to unclear application of efficiencies in simulations and for power estimation. Ventilation simulations using "fixed flows" and software default fan efficiency values to specify fan duties may result in omission of fan s...

A fan's operational reliability is a critical factor in ensuring that an underground mine's primary ventilation system enables and sustains the mine's continuous operation. At a time when underground mining operations are required to access ore bodies located at ever greater depths, primary ventilat...
