What is an auxiliary fan?

Explanation:
An auxiliary fan is a supplementary underground fan used to direct ventilation to a particular part of the mine. It’s not the main surface or underground fan that handles bulk air movement, and it isn’t a fan dedicated to cooling or to a gas scrubber. Instead, its job is to boost or redirect airflow to a specific section—such as a long heading, working face, or an area with poor ventilation—by overcoming resistance in the airway and ensuring that portion receives adequate air changes. This targeted support helps dilute and remove contaminants where the main flow doesn’t reach effectively.
