Abstract

The advanced seismic detection technology with tunneling based on TBM rock-breaking source is an important guarantee for the application of TBM in underground mine. In order to solve the problems in the observation method and data processing of this technology, an observation system based on MSP mine seismic wave advanced detection was designed. The seismic record reconstruction technology based on cross-correlation and deconvolution composite interference was applied and verified, and the reflection wave field extraction technology based on F-K domain and τ-p domain joint filtering was proposed and verified. The research showed that the observation system could realize separation and utilization by means of the negative apparent velocity characteristics of the reflected wave in front of the roadway. The composite interference effectively suppressed the long-continuation peak pulse interference and the high-recovery wave group information. The joint filtering could suppressed the spatial aliasing caused by the small number of sampling channels in the F-K domain filtering, and the τ-p domain filtering was easy to produce the phenomenon of aliasing or low frequency, which could provide technical support for TBM advanced seismic detection technology with tunneling.
