结合炭煤矿水文地质特征,分析了主要含水层和隔水层对突水的影响,研究了炭煤矿突水防治问题.结果表明,巷道底板灰岩裂隙发育,水压较高,加之矿压影响是造成奥陶系灰岩寒武系灰岩突水的主要原因.采用先封堵巷道截流再钻探延伸封堵奥陶纪灰岩裂隙治源的综合注浆堵水方案,并在较大面积内加固顶底板,堵水率可达到90%.此方法为解决炭煤矿动水注浆堵水问题提供了参考.

On the basis of the hydrogeology features of Tanmei Coal Mine area and the effect of the main aquifers and aquifuges, the reason why the Tanmei Coal Mine water bursting occures is pointed out after the analysis and research of the water bursting in the coal mine. As the roadway is excavated, the fracture of limestone develops in the floor, leading to water-dripping serious and water pressure higher, which is the main reason of water bursting under additional underground pressure. In order to prevent water outburst, the construction scheme of surface grouting through a drilling hole is adopted and the roof is reinforced in some bigger areas. After these manipulations, the plugging rate is more than 90% , and the task of dynamic water grouting is successfully fulfilled. What is more, all of these could be a good example of preventing water outburst for some similar mines.
