Analysis of connecting a forcing fan to a multiple fan ventilation network of a real-life mine

The results of the analysis let us draw a conclusion that a significant increase in the total air supplied to the mine with a complex structure of the ventilation network is difficult to obtain using underground forcing fans. The only tangible benefit of the presented solution is a change in air distribution in excavations located a short distance from the downcast shaft at which a forcing fan could be installed. An increase in airflow rates in mining districts located near this shaft is possible. However, it must be remembered that connecting the forcing fan in one downcast shaft of the multi-shaft network decreases airflow into other downcast shafts.
