摘　　要：为了解决6306综采面巷道顶板易破碎、煤壁易片帮的问题,提出采用“注浆加固+棕绳加固”的控制方案,利用FLAC仿真分析软件对该方案的有效性进行了仿真验证,确定了加固工作方案的技术参数,并对在井下注浆加固和棕绳加固的应用情况进行了论述,根据实际应用表明,该控制方案能够彻底解决井下煤壁片帮问题。In order to solve the problems of easy fragmentation of the roof and coal wall fragmentation in the 6306 fully mechanized mining face roadway,a control scheme of"grouting reinforcement+brown rope reinforcement"is proposed.The effectiveness of this scheme is simulated and verified using FLAC simulation analysis software.The technical parameters of the reinforcement work scheme are determined,and the application of grouting reinforcement and brown rope reinforcement in the underground is discussed.According to practical applications,it is shown that this control scheme can completely solve the problem of coal wall fragmentation underground.
