摘要
为了减少突出煤矿的安全隐患,提出了智能防爆应急风门系统的慨念;介绍了设备安设地点和工作原理;分析了矿井全风压E点的通风变化情况,风路BE的判别式,不设应急风门系统的安全隐患;通过案例分析,得出了发生小型突出时,应急风门系统不仅能有效的利用矿井主风机风压,还能阻止突出瓦斯逆向,也能安全调控瓦斯浓度在爆炸界限之外经回风巷安全的排出至地面,还能防止瓦斯燃烧时火焰在巷道中蔓延,有利于节约排瓦斯的时间,更有利于安全救灾避灾,以减少突出后的次生灾害发生,智能防爆应急风门系统设计具有可行性。
To reduce potential safety hazard of coal mine, we proposed the concept of intelligent explosion-proof emergency air door system and introduced installed location and principle of the equipment, analyzed ventilation changes of mine total wind pressure point E, and the discriminant of air duct BE, safety hazard without emergency air door system. Through the case analysis, we obtained that the emergency air door system can not only effectively uses mine main fan pressure, but also can prevent gas reverse and safely control the gas concentration discharge to the ground by return air lane outside the explosion limit and can prevent gas burning flame spread in the roadway when the small outburst occurred, which saves gas drainage time, more conducive to safety, and reduces secondary disasters after outburst. The design of intelligent explosion-proof emergency damper system is feasible.
