Application of multi-method geophysical techniques in geological exploration of open-pit mine slope

In order to investigate the underground distribution and morphology of open pit mine geological bodies, multi-method geophysical methods (AGI high-density electrical method and EH4 electromagnetic surveying method) are used to conduct geological exploration on open pit mine slope, making full use of that the anti-interference ability is strong, and the shallow measurement accuracy is high of the AGI high-density electrical methods, and the EH4 electromagnetic surveying has the advantages of large depth of detection and wide coverage, and the geological structure of the mine slope is accurately detected.The results show that there are two large fault structures in the western slope of the mining area, and the structural belt is wide and the secondary structure is relatively developed.The water-rich area is large and deep, which has an adverse effect on the overall stability of the mine slope.The detection results can provide a strong guarantee for the subsequent mining design and safe production.
