Application Study of Drift Seismic Prospecting for Faults Ahead of Tunnels
Abstract：In the construction of intelligent coal mines, the primary task is to achieve transparent geological conditions and accurately identify hidden geological anomalies ahead of excavation. One of the main geological problems during tunnel excavation is unclear structures. Drift seismic prospecting involves placing seismic sensors behind the tunnel and using the vibrations generated by the mining machine cutting coal and rock as a source for real-time data acquisition. By combining techniques such as interference stacking, drift seismic data are converted into active pulse signals. Then, through diffraction migration processing of the active pulse signals, analysis results are obtained. Finally, the method of verifying predicted anomalies by actual exposure is used to accurately locate hidden structures within 100 meters ahead of the tunnel, providing important technical support for safe face excavation.
