矿井反射槽波包络叠加成像方法及其应用
发布时间：2018-08-09 15:53
【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 the slot wave encounters discontinuous section such as fault, it will produce reflection and be received by the geophone located in the same tunnel as the shot point, so that the geological anomaly of the side of the tunnel can be detected. In general, the energy of reflected grooves is weak and the signal-to-noise ratio is low. In order to improve the signal-to-noise ratio (SNR) of reflected grooves, the envelope superposition method is applied to the detection of reflected grooves in a coal mine of Yangquan Coal Group, Shanxi Province, as an example, and the numerical simulation of 3-D grooves in fault models and the verification of actual detection data are carried out. The effectiveness of the envelope superposition imaging method is verified.
