A mine ventilation booster fan is a primary fan that is installed in series with another primary fan.
Without the booster fan operation, the total mine airflow will fall significantly. Booster fans are typically installed as mine develops and primary fan no longer has the pressure or flow capability to service increased resistance of operation.
In this sense, the booster fan operates as an integral and “symbiotic” unit with the original primary fan to provide sufficient total airflow for mine.
Mine booster fans are technically main fans that are installed underground to maintain required airflow by overcoming the mine resistance.
Booster mine ventilation fans can reduce the pressure of the main fan and decrease system leakage and the total required air power.
A mines booster fan is an underground ventilation device installed in the main airstream (intake or return) to handle the quantity of air circulated by one or more working districts. It is installed to operate in series with the main fan and boost the air pressure of ventilation air passing through it.
Provision of additional air quality at strategic locations within the mine and separate from longwall split.
Increased pressure to drive airflow into working splits-
Reduction of intake to return pressure differential, out bye of the booster fan location
Reduction in out bye leakage
Reduction of main fan airflow requirements for a given in bye performance
Optimization of power utilization
