When using auxiliary fans, what should be minimized?

Minimizing recirculation of air is crucial when using auxiliary fans in mining operations. Effective ventilation is essential in underground environments to ensure that fresh air reaches workers and dilutes hazardous gases or dust. Recirculated air can lead to an accumulation of contaminants, reducing air quality and posing health risks to miners. By ensuring that these fans minimize recirculation, you enhance the overall effectiveness of the ventilation system and maintain a safer working environment.

While noise pollution, power consumption, and heat generation are also important factors to consider in the operation of auxiliary fans, the primary goal should be to provide a constant flow of fresh air. Thus, minimizing recirculation directly impacts the health and safety of personnel working underground.
