【摘要】 为进一步探测陕西水帘洞煤矿ZF3806工作面回采巷道顶板围岩的破裂状态，指导回采期间巷道加强支护，对工作面煤层及其顶底板岩石进行超声波波速测定，并采用槽波地震勘探技术对该工作面进行透射槽波探测.研究结果表明，4号煤层与其顶底板岩层的波速存在明显差异，为槽波勘探提供了物理基础；透射槽波CT成像解释槽波能量异常区域6个，判定异常区域破碎度大，裂隙较发育，建议在工作面回采过程中对异常区域的巷道顶板进行加强支护，保证工作面的安全回采.更多还原

【Abstract】 In order to further explore the fractured state of the roof rock of the ZF3806 working face in Shuiliandong Coal Mine, Shaanxi Province, and guide the strengthening of support during the mining period, ultrasonic wave velocity measurement is carried out on the coal seam and its roof and floor rocks of the working face. Slot wave seismic exploration technology is used to conduct transmission slot wave detection on the working face. The research results indicate that there is a significant difference in wave velocity between the 4th coal seam and its roof and floor rock layers, providing a physical basis for trough wave exploration. Transmission slot wave CT imaging interprets 6 abnormal areas of slot wave energy. It is speculated that these abnormal areas have high fragmentation and well-developed fractures. It is recommended to strengthen support for the roof of the abnormal areas during the mining process of the working face to ensure safe mining.更多还原
