Abstract

<p>Mine ventilation is a critical component of underground coal mining operations, ensuring the supply of fresh air and the removal of hazardous gases, dust, and heat. This study focuses on the performance analysis of an auxiliary mine fan in a duct system to understand the relationship between airflow, pressure, and system resistance. Key performance parameters, including static pressure, velocity pressure, and air velocity, were evaluated through experimental data collected from multiple mine scenarios. The study reveals that Mine B achieved the highest airflow of 5.03 m&sup3;/s and velocity of 10.0 m/s due to optimal duct diameter and pressure. The findings emphasise that controlling airflow by adjusting fan speed is significantly more energy-efficient than traditional throttling methods.</p>
