Abstract: In view of the existing multiple types of complex geological structural abnormal problems such as faults, collapse columns and others in the 30225 working face and its northern area of Sanyuan Nanyao Xiaochang Coal Mine in Changzhi, Shanxi Province, based on slot wave seismic exploration theory, this study conducts an organic combination of transmission-based energy attenuation CT imaging technology and reflection-based profile imaging technology to achieve precise detection and comprehensive identification of regional geological structures. The research results indicate that this collaborative technology effectively identifies four major geological anomaly areas (CT-1 to CT-4) in the working face and northern area. The geometric position and morphological characteristics of the detection results are highly consistent with the known geological structures and 3D seismic data of the mining area, providing significant information for more precise revelation of the geological structure of the 30225 working face, and providing key geological basis for safe and efficient mining of the working face, meanwhile, it also determines the accurate target areas for subsequent drilling verification.
