潞宁煤矿阀门井CO裂隙封堵紧急处理方法实践

Practice on Emergency Treatment for CO Fracture Sealing in Valve Well of Luning Colliery

针对潞宁煤矿正常生产过程中发现的阀门井内部两侧及迎头和底板出现塌陷裂隙并有CO进入管道沟的情况,采用"风筒布铺底+黄土装袋封堵+水泥抹面"的方法进行紧急处理,并通过注浆等方式完成后续处理,有效防止了高浓度CO向阀门井内涌出,避免了事故发生,处理过程迅速有效,为类似情况处理提供参考。

Aiming at the collapsing fracture on both sides of the valve well and at head and bottom and the entry of CO into pipe trench in normal production process in Luning Colliery,the author proposes the emergency treatment with cloth bedding in wind tube,bagged-loess plugging and cement plastering surface together with grouting,which can effectively prevent the emission of high concentration of CO in valve well to avoid accidents and provide a reference for similar cases.
