摘要：为有效探测煤层厚度、构造、采空区等,科学指导矿井安全、高效生产,使用德国SUMMIT-ⅡEX槽波地震仪,采用透射法,在选定适宜频率进行波速成像后,根据波速与煤层厚度的负相关关系,实现了煤层厚度的定量化解译,准确率达86%。采用反射法,利用槽波沿煤层传播时遇到断层等波阻抗界面产生反射的现象,根据槽波传播速度及反射波到达检波器的时间,计算并预测了走向断层位置,偏差小于5 m。另外,在探测采空区、地应力集中区、瓦斯富集区、突水风险区等方面开展探测试验,取得了有价值的成果。槽波具有只在煤层中传播、携带信息多、探测距离远等优点,槽波地震勘探技术是一种有效的矿井物探手段,具有良好的应用前景。

Abstract：In order to effectively detect coal thickness, structure, goaf, and then guide the coalmine safety with high-efficient production, SUMMIT-ⅡEX channel wave seismograph is used in Yima Coal Group.Transmission method is applied to detect the coal thickness.Based on the negative relations between the wave velocity and the coal seam thickness, the quantitative interpretation of the coal thickness is realized and the prediction accuracy reaching 86%.Reflection method is applied to detect the strike fault with the reflect of channel wave when it meet wave impedance interface such as fault during traveling along the coal seam.According to the channel wave propagation velocity and the reflection time of arrival in detector, the fault location is calculated and predicted.The actual deviation is less than 5 m.Meanwhile, the seismograph has been tentatively applied to detect gas zone, the risk area of rock burst and water inrush.The preliminary valuable results are achieved.The channel wave detection technology is an effective method of mine geophysical exploration and has a good prospect.
