Out of sight, and out of mind: at many mines, fans run at maximum capacity around the clock, regardless of demand. The consequences of this approach are costly: excessive energy consumption, equipment wear, and dust generation complicate an already complex underground environment.
In contrast, ventilation-on-demand (VOD) systems automatically adjust airflow based on real-time conditions, such as personnel location, equipment activity, and air quality data.
Learn more about ventilation systems at mine sites in this North American Mining Magazine article, featuring commentary from Paul Aho.
