Method and application of reflected in-seam wave enveloped superpositionimaging in coal mine

WANG Yi

摘要

摘要: 槽波在遇到断层等不连续断面时，会产生反射并被与炮点位于同一条巷道内的检波器接收到，据此可以探测巷道侧帮地质异常发育情况。通常情况下反射槽波能量较弱，信噪比较低。为提升反射槽波信噪比，以山西阳泉煤业集团某矿201工作面为例，将包络叠加方法应用于反射槽波探测，并通过断层模型三维槽波数值模拟以及实际探测资料的验证，证实了包络叠加成像方法的有效性。

Abstract: When in-seam wave encounters discontinuous section, such as fault, it will generate reflection and be received by geophone placed in the same tunnel with shot point, which can be used to detect the geological anomaly in the side of tunnel. In normal case, reflected in-seam wave has the disadvantage of weak energy and low signal-to-noise ratio. To raise the signal-to-noise ratio of reflected channel wave, this paper apply the enveloped superposition imaging method on the detection of reflected in-seam wave. Besides, the data of 3D numerical simulation and mining verified case also proves the effectiveness of reflected in-seam wave envelop superposition imaging.
