摘　　要：为了解决青岗坪煤矿主井风流紊乱的问题,利用风压平衡定律对其通风系统进行分析,推导了风流紊乱的判别式;在通风阻力和自然风压测定的基础上,利用实测数据对判别式进行验证;结合判别式和现场实际情况,提出防治风流紊乱措施。结果表明措施的实施,使得主井风流在自然风压最大时依然正常,既增强了矿井通风系统稳定性,又提高了其抗灾性。In order to solve the air disorder in main shaft of Qinggangping coal mine,the law of air pressure balance was used to analyze the ventilation system,and derived discriminant of the air disorder.The real data is used to verify the discriminant which was measured in mine ventilation resistance and natural ventilating pressure.Combining the discriminant and the practical situation,the measure was provided to prevent the air disorder.After applying the method,the airflow direction was normal when the natural ventilating pressure reached a maximum,which enhanced stability of the mine ventilation system and improved its ability of fighting against disaster.
