Abstract The Yaochong molybdenum deposit is a medium-sized deposit, in which hydrogeological work has been done. For the purpose of investigating the properties of the aquifer, especially the relationship of the "V"-shaped fracture to the weathering fissure aquifer and the fracture veined aquifer, the authors used EH-4 to conduct profile measurement of the "V"-shaped fracture. The results show that the four electromagnetic sounding profiles measured in the Yaochong mining area can clearly detect the distribution and influencing range of the "V"-shaped fracture zone, that the audio-frequency magnetotelluric sounding can better solve the problem of the unification between the weathering fissure aquifer and the fracture veined water, and that the essential factors of the aquifer such as its thickness and its geological boundary can be demonstrated quite audio-visually. The results obtained by the authors can play a considerable role in the prediction of the inflow of water in the mining area in the future.
