摘　　要：龟兹矿业A3煤层A303采煤工作面矿压作用时间集中、间隔时间长、周期性相对明显,极易发生顶板大面积冒落事故,对井下作业安全产生了严重影响,提出了一种新的水力致裂改造坚硬顶板缝网的技术,对其理论、参数设计、应用情况等进行了细致的分析,形成了完整的应用理论。实际应用表明,水力致裂改造坚硬顶板缝网技术能够有效解决井下顶板悬顶垮落的情况。The A303 coal mining working face of the A3 coal seam in Qiuci Mining Industry has a concentrated action time,long interval time,and relatively obvious periodicity of mining pressure,which is prone to large scale roof caving accidents and has a serious impact on the safety of underground operations.A new hydraulic fracturing technology for transforming the hard roof sewing net is proposed,and its theory,parameter design,and application situation are analyzed in detail,forming a complete application theory.The practical applications show that the hydraulic fracturing transformation of hard roof sewing net technology can effectively solve the situation of roof suspended roof collapse in underground mines.
