Application of natural-source surface wave exploration in Xiaobaozhuang iron deposit of Anhui Province

In order to study the application effect of the natural-source surface wave exploration method in solid mineral exploration, especially in deep mineral exploration, the authors in this paper carried out study on the known exploration line of Xiaobaozhuang iron mine. The natural-source surface wave survey points were deployed in the linear way based on previous research, and a total of 32 survey points with a total length of 3 100 m were completed. The extended space autocorrelation method was used to obtain the dispersion curve of each measurement point, and shear wave velocity structure of the whole section was obtained by the inversion of dispersion curve and interpolation calculation. The stratigraphic structure and faults were divided according to the geological and borehole data. These exploration results were proven to be good, compared with the known data, indicating that the natural-source surface wave exploration method has a good application prospect, and the deep part of the study area has great prospecting potential.
