摘　　要：针对晋城矿区超长工作面无法有效探测隐伏构造的难题,对采用槽波探测技术进行了探测研究。结果表明,槽波探测技术可有效探测出超长工作面内陷落柱、破碎区、应力增高区等地质异常区。以某矿5308工作面为研究对象,通过对槽波透射法的观测系统、槽波主频、频散曲线及速度分析,推断出该工作面存在6处异常,包括2处应力增高区,1处陷落柱,1处瓦斯富集区,2处煤层破碎带或断层。随后与已有物探资料、钻探资料及揭露资料进行对比分析,得出槽波探测技术可以有效地解决超长工作面隐伏构造探测难题。In view of the problem that Jincheng mining area can not effectively detect concealed structures on long working face,the authors made an exploration study on in-seam seismic wave detection technology. The results show that,in-seam wave surveying technology can effectively detect the collapse pillar,crushing zone,stress concentrated areas and other geological anomalies in long working face. In this paper,the 5308 working face of a mine was taken as the research object,6 anomalies were found from the observation system,frequency,dispersion curve and velocity analysis of in-seam seismic wave,including 2 stress concentration areas,1 collapse column,1 gas enrichment zone,2 coal seam fracture zone or fault. And then compared with the existing geophysical data,drilling data and revealing data,it is concluded that the in-seam seismic wave detection technology can effectively solve the problem of concealed structure detection on super-long working face.
