摘　　要：为了研究煤矿井下发生爆炸后因通风系统受损停风而造成的危害,分析了爆炸冲击波对井下巷道、电气设备、风门管道等通风系统的具体损毁情况,探讨了防爆井盖被冲开后导致风流短路的危害,研究了因停风而导致井下烟流紊乱、有害气体和瓦斯浓度升高、灾害区域扩散蔓延、氧气浓度下降、甚至引发二次爆炸等各种危险因素及灾害后果.结果表明:在煤矿发生爆炸后人员未全部安全升井前应保持持续通风,应开发出必要的设备防止井下风流短路,从而减少爆炸事故造成的伤亡人数,降低灾害后果.After explosion of the coal mine underground, the ventilation system will be damaged. In order to study the harm because of no wind, it is analyzed the specific damage situation of the ventilation system which involved the tunnel underground , electrical equipments , dampers and pipeline, studied the new risk factors and harmful consequences without wind. Causing no wind in the underground well, analyzed the risk factors include smoke flowing disorders, rising gas density, declining oxygen concentration, expanding the disaster area, and even lead to second explosion and other dangers. The result showed that the coal mine should be maintained continue to ventilate, develop necessary facility to avoid airflow short, which could decrease the casualties after an gas explosion, before the personnel inclined safely.
