This paper discusses the findings of a study focused on optimizing auxiliary fan locations to minimize air recirculation in dead-end crosscuts where diesel-powered vehicles operate in underground mining environments. The objective was to determine the most efficient placement of auxiliary fans to control diesel particulate matter (DPM) concentrations. A combination of field monitoring and computational fluid dynamics (CFD) simulation studies assessed various airflow rates—1.0, 1.5, and 2.0 times the capacities of twin fans—placed at distances ranging from 1 to 10 meters from the crosscut entrance. Results indicated that in an unventilated 70 m crosscut, a reduction of DPM concentration from 820 μg/m3 to 100 μg/m3 required 6 hours. It was observed that air recirculation occurred with airflow equal to fan capacity but decreased as the fan was positioned further from the entrance. Importantly, no recirculation was noted when intake air surpassed 150% of the fan capacity with specific fan positioning, providing key insights for effective ventilation strategies in underground mining operations.
