【摘要】：槽波在遇到斷層等不連續(xù)斷面時(shí),會(huì)產(chǎn)生反射并被與炮點(diǎn)位于同一條巷道內(nèi)的檢波器接收到,據(jù)此可以探測(cè)巷道側(cè)幫地質(zhì)異常發(fā)育情況。通常情況下反射槽波能量較弱,信噪比較低。為提升反射槽波信噪比,以山西陽(yáng)泉煤業(yè)集團(tuán)某礦201工作面為例,將包絡(luò)疊加方法應(yīng)用于反射槽波探測(cè),并通過(guò)斷層模型三維槽波數(shù)值模擬以及實(shí)際探測(cè)資料的驗(yàn)證,證實(shí)了包絡(luò)疊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.
