Description
Summary:The purpose of this paper is to discuss the feasibility of utilizing the non-explosive source green seismic exploration technology to detect mineral resources in the deep of complex mountainous areas of western and southern China as well as to provide a feasible detection scheme. Based on seismic illumination analysis and prestack depth-domain migration experiments, a viable active-source seismic detection system was designed for the Zhuxi mining area of Jingdezhen. Geophysical models were established according to the combined drilling profile of L42 and the corresponding petrophysical measurements of rocks based on geological findings, drilling results, and site investigations. Since the single-component p-wave seismometers would be primarily utilized for the subsequent seismic data acquisition, the viscous-acoustic wave equation was selected to simulate the propagation of the seismic wave. Meanwhile, the acoustic-elastic boundary approach (AEA) was used to solve the irregular free-surface problem caused by the rugged Earth’s surface. Seismic source-receivers bidirectional illumination analysis and prestack depth-domain reverse time migration experiments were performed on simulated seismic data with 20 dB high SNR (signal-to-noise ratio) and 6 dB low SNR, respectively. The results of this study showed that by adopting a dense exciting-receiving seismic detection system, the eco-friendly non-explosive seismic source technology could reveal the spatial distribution of the main strata underneath the target area and the ore-controlling structures like faults and overthrust nappes. Based on this study, the next step of seismic data acquisition was implemented. The first-hand non-explosive source seismic profiles of the Zhuxi mining area demonstrated that the detection scheme designed was feasible and effective. By constantly improving the technical system, the eco-friendly non-explosive active-source technology would provide a safe and efficient approach, which could be used in the research fields of deep mineral resource prospection, buried faults exploration, urban underground space detection, etc. Finally, the proposed design and demonstration of an active-source seismic detection system based on illumination analysis and migration experiments merits further study and applications.
