煤矿综放工作面地面注浆堵水工程实践

Ground Grouting Water Blocking Practice in Coal Mine Fully Mechanized Caving Face

针对某煤矿综放工作面突水严重,采用地面注浆堵水法进行工作面突水治理,通过选择合理的注浆工艺和注浆材料实施注浆工程施工,然后观测注浆后井上、下水文的变化情况,结果表明利用注浆堵水法可成功实现井下综放工作面突水灾害的治理,为其他类似矿井的突水灾害治理提供了技术指导。

Aiming at the serious water bursting in a fully mechanized top coal caving lace m a coal mine, the ground watering method is used to control the water inrush. By selecting reasonable grouting technology and grouting material, the grouting construction is carried out, and then the change of hydrological up and down after grouting is observed. The results show that the use of grouting water shutoff can successfully realize the treatment of water inrush from the fully mechanized top coal caving mining face, and provide technical guidance for the management of watedogging in other similar mines.
