煤矿井下顶板水力压裂技术应用研究

Application Research on Hydraulic Fracturing Technology of Underground Roof in Coal Mines

针对赵庄矿井下顶板厚度大,难以自行垮落的不足,提出了一种井下顶板水力压裂方案,对该方案的原理和方案设计过程进行了分析。实际应用表明,采用井下顶板水力压裂技术能够有效控制顶板的垮落范围,对提升井下作业安全具有十分重要的意义。

In view of the deficiency that the underground roof of Zhaozhuang Coal Mine is thick and difficult to collapse by itself,this paper put forward a underground roof hydraulic fracturing scheme,and analyzed the principle and design process of the scheme.The practical application shows that the underground roof hydraulic fracturing technology can effectively control the roof collapse range,which is of great significance to improve the safety of underground operation.
