摘　　要：为解决岳城煤矿5307工作面过构造影响区域冒顶漏矸、推进困难的问题,采用槽波地震勘察技术对工作面内煤层发育及隐伏构造赋存情况进行探查,提出在顺槽巷道进行深孔预注浆加固破碎煤岩体。现场应用结果表明:通过槽波地震勘探与深孔预注浆加固联合技术的成功应用,液压支架与顶板接触状态得到明显改善,支架稳定性明显增强,构造影响区域工作面推进度明显提升。In order to solve the problems of roof fall,gangue leakage and difficult advancing in crossing the structure zone at 5307 working face of Yuecheng Colliery,the author proposes the deep hole pre-grouting reinforcement of fractured coal rock bodies in the roadway by exploring the development of coal seams and the hidden structures occurrence through channel wave seismic survey technology,whose on-site application results show that the combined technology has significantly improved the contact state between the hydraulic support and the roof with significant reinforcement of the support stability.
