In underground mines, it is common for duct-fan auxiliary ventilation to extend over hundreds, in some cases thousands of metres. Typically, they are push systems made of either a single or twin vent line with one or two head fans in series, while some systems also use Booster Fans to supply the additional pressure to maintain the airflow.
The main objective of an underground ventilation system is clear: provide air flows in sufficient quantity and quality to dilute contaminants to a safe amount. Ventilation …
