Application of AGI and EH4 in geological exploration of open pit slope

Both AGI high-density electrical method and EH4 magnetotelluric method are currently used in the field of engineering geophysical exploration with relatively satisfactory results. By combining AGI and EH4 detection methods and co-applying them in the geological exploration of the open pit slope of metal mine, the advantages of high-density electrical method such as strong anti-interference ability, high precision of shallow survey, large depth of EH4 detection and wide coverage can be effectively combined. In this way, the abnormal geological structure of the mine slope site is detected more accurately, and it is concluded that there are two groups of large fault structures in the western slope of this mining area. And the structural belt is wide, the water-rich area is large and the depth is deep, which has adverse effects on the overall stability of the mine slope, and also provides guarantee for the follow-up mining design and safety production.
