Application of collapse column identification using 5-dimensional high-density seismic data in OVT domain
The collapse column water damage poses a threat to coal mine safety production,focusing on the unique issues associated with collapse column,it utilized all-digital high-density three-dimensional seismic exploration technology,chiefly applying five-dimensional seismic interpretation techniques based on the OVT domain.By analyzing the differences in seismic data in the OVT domain,stacking was carried out according to different azimuth angles and offsets,and in-depth analysis of seismic reflection characteristics in the stacked profile was conducted to explore the advantageous orientation where the response characteristics of collapse columns were more sensi-tive.The study confirmed that profiles of the dominant azimuth angle more effectively reflected the anisotropic properties of geological tar-gets linked to collapse columns compared to traditional stacking profiles.Profiles from shorter offsets displayed a higher and wider frequen-cy band,enabling a more precise identification of collapse column distributions,thus increasing the success rate of drilling of collapse col-umns.This study provides a guide for studying seismic reflection characteristics of collapse columns from various perspectives and offset distances,breaking through the limitations of original single-profile analysis,enhancing the reliability of seismic reflection features of col-lapse columns,significantly improving the accuracy and reliability of subsidence column identification.The research demonstrates the supe-riority of this technique in detecting geological anomalies in regions suspected of containing collapse columns.
