Research on three-dimensional imaging technology of underground ore body by magnetic method and seismic data joint inversion

The accurate detection of underground ore bodies is of great significance for the exploration and development of mineral resources. The traditional single exploration method has limitations, and it is difficult to meet the high-precision requirements for three-dimensional imaging of the ore body. In this paper, a three-dimensional imaging technology of underground ore body based on the joint inversion of magnetic method and seismic data is proposed. By integrating magnetic and seismic exploration data, the joint inversion algorithm is utilized to improve the inversion accuracy of the underground ore body model. The basic principles of magnetic and seismic data and the theoretical framework of their joint inversion are introduced; the joint inversion process based on data acquisition, preprocessing and inversion algorithms is designed, and the realization method of the 3D imaging technology is proposed and verified by combining with real mine data. The accuracy and reliability of the inversion results are evaluated, and it is proved that the application of this method in ore body imaging is better than the traditional single method. The study shows that the joint inversion of magnetic method and seismic data can significantly improve the accuracy and resolution of 3D imaging of underground ore bodies, and has a wide range of application prospects.
