In the process of coal mining,it is necessary to realize the importance of ventilation management,constantly pay attention to the measurement of actual ventilation resistance underground,optimize the ventilation system in a timely manner,and ensure ventilation effectiveness.A detailed analysis was conducted on the framework of the coal mine ventilation system,and the resistance of the ventilation system was measured using a barometer method.The results showed that there were significant air resistance in the inlet,outlet,and return sections.Therefore,based on the later mining situation,detailed ventilation system optimization measures were formulated,which not only reduced the wind resistance of the roadway,but also improved the stability of underground air supply.
