摘　　要：为解决朱集东矿大采高工作面受大落差断层影响破碎围岩支护难题,结合矿井实际情况,采用"加强支护+超前两巷注浆+工作面动态注浆"的方式加固顶帮,并提出两种设计方案,采用数值模拟、监测分析验证效果。结果表明,方案二较方案一顶底、两帮移近量分别减少27%和54%,较原支护方式顶底、两帮移近量分别减少77%和85%,顶帮围岩明显改善。In order to solve the problem of broken surrounding rock support in large mining height working face of Zhujidong Coal Mine affected by large drop fault,combined with the actual situation of the mine,the method of"strengthening support+advance two roadway grouting+working face dynamic grouting"is adopted to strengthen the top wall,and two design schemes are put forward,and the effect is verified by numerical simulation and monitoring analysis.The results show that,compared with the first scheme,the approach amount of the second scheme decreases by 27%and 54%respectively,and the approach amount of the second scheme decreases by 77%and 85%respectively.The surrounding rock of the top wall is obviously improved.
