摘　　要：为保证燕子山煤矿东区4#层盘区主要进风路线上发生外因火灾时,能采取迅速有效的反风措施,保证作业人员生命安全。对假定东区4#层盘区主要进风路线上发生外因火灾时实施区域性反风的必要性进行分析,在矿井通风阻力测定的基础上,计算出发生火灾时,正、负压风流汇合点位置,并在上述位置构筑相应的通风设施。经区域性反风演习结果:反风率达到76.25%,按4#层盘区内1采2掘1备人员计算,可确保此区域现场200人以上作业人员安全。in order to ensure the safety of the working personnel, we can take quick and effective anti-wind measures when there is an external fire on the main incoming wind route in the 4 # laminar zone in the East area of yanzishan coal mine. Based on the determination of the ventilation resistance of the mine, the position of the confluence points of positive and negative pressure winds is calculated. And build corresponding ventilation facilities in the above locations. According to the results of the regional anti-wind exercise, the anti-wind rate reached76.25 %. According to the calculation of 1 mining, 2 excavation and 1 reserve personnel in the 4 # layer plate area, the safety of more than 200 operators in this area can be ensured.
