Abstract
In order to study the mechanism of floor water outburst in deep mining,taking No.2129 Face of Xingdong Mine as the background,the relationship between the failure depth of floor strata and the hanging roof length of main roof of working face was established by theoretical calculation,and the idea of using hydraulic fracturing technology of main roof to reduce hanging roof length of roof and control floor water outburst was put forward.The UDEC was used to simulate the stress evolution law of the bottom plate under different fracturing intervals,which showed that the bottom plate control effect was the best when the fracturing interval was below 40 m.After the hydraulic fracturing of the roof,the mine pressure observation results showed that the periodic weighting step distance of No.2129 Face was significantly reduced,indicating that the technical means adopted were reasonable and effective.关键词
