摘要(Abstract)：

工作面内隐伏断层不仅严重影响煤炭资源的高效回采,而且给煤矿安全生产带来了潜在威胁。通过对工作面内隐伏断层的槽波地震数值模拟,证实了槽波透射法探测隐伏断层的可行性。采用全息观测方式对45301工作面进行了透射槽波探测,通过频散分析及CT成像,查明了工作面隐伏断层分布情况。探采对比表明,透射槽波探测技术能够有效探查工作面内部的隐伏断层,为煤矿安全开采提供有效技术支撑。
The concealed fault influences not only the highly efficient extraction of coal resources, but also brings potential threat for safe production in coal mine. The paper conducted in-seam seismic numeric simulation for the concealed fault in a working face, verified the feasibility of the detection of the consealed fault by transmission method. Then the holographic observation was used to conduct transmission in-seam wave detection in working face 45301, through analysis of frequence dispersion and CT imaging, the distribution of the conceraled faults in working face was found out. The comparison of the detection and the mining show that the transmission in-seam detection tehnique can efficiently detect the consealed faults in working face, provide efficient technical support for safe mining in coal mine.
