摘　　要：槽波地震勘探技术可以有效探查煤层中小断层、陷落柱等地质异常体,在探测精度和距离上明显优于其他煤矿井下勘探方法。透射法作为基本的槽波地震探测方法,具有简单灵活、探测范围大、准确率高等优势。采用透射槽波方法对实际煤矿工作面内断层构造进行探测研究,通过滤波、频散分析、波场及速度分析、能量分析以及透射CT成像等关键技术对实际透射槽波数据进行精细处理,获得准确的透射槽波成像剖面。根据槽波在煤层中受到断层阻断或遇到煤层破碎时其能量将急剧降低的特征,利用透射槽波能量CT剖面,并结合实际揭露情况,解释出12条可靠断层。通过实际煤层工作面透射槽波勘探方法测试,验证了透射槽波方法的有效性以及在煤田断层等构造探测中的实用价值。The technology of in-seam seismic exploration can effectively detect small faults,collapse columns and other geological anomalies in coal seam,and is obviously superior to other underground exploration methods in detection accuracy and distance.As a basic in-seam seismic detection method,transmission method has the advantages of simple and flexible,large detection range and high accuracy.In this paper,the transmission in-seam wave method is used to detect the fault structure in the actual coal mine working face,and the transmission in-seam wave data are carefully processed through the key technologies such as filtering,dispersion analysis,wave field and velocity analysis,energy analysis and transmission CT imaging,so as to obtain the accurate transmission in-seam wave imaging profile.According to the characteristics that the energy of the in-seam wave will decrease sharply when it is blocked by faults in coal seam or when the coal seam is broken,12 reliable faults are explained by using the energy CT profile of the transmission in-seam wave and combining with the actual disclosure.Through the test of the transmission in-seam wave exploration method in coal seam face,the validity of the transmission in-seam wave method and its practical value in the detection of coal faults and other structures are verified.
