高压注水在掘进工作面防突中的应用

Application of High-pressure Water injection for Coal and Gas Outburst Prevention in Driving Face

针对某矿高瓦斯煤层掘进工作面掘进速度慢,施工困难等问题,现场应用高压注水防突措施,不仅有效的防治了煤与瓦斯突出,而且使巷道掘进期间瓦斯涌出变得更加均匀,从而有效地保证了施工安全,改善了作业环境。

With consideration of the problems such as slow driving and difficult construction in a driving face of a colliery with high gassy seam,the measure of high-pressure water injection was used to control coal and gas outburst,which has not only made the gas emission more uniform during driving period but also effectively ensured the construction safety and improved the working environment.
