 This study examined four different scenarios involving the placement of an auxiliary ventilation system in an underground mine. The results were validated using actual data collected from the mine. The study found that the optimal location for the auxiliary ventilation system was dependent upon the variables being measured, temperature, air velocity, or specific area. In general, placing the system closer to the phase resulted in better performance than placing it at the bottom of the drift. However, the exact location of the system should be determined based on the particular scenario being considered. This study provides valuable insight into how to optimize auxiliary ventilation systems in mines, which could lead to improved safety and efficiency.
