For the mining of ionic rare earth ore (IREO) by in-situ leaching, the fracture structure, underground river and karst cave developed beneath the ore body, will become leakage pathways for the leaching liquors to escape and seriously reduce the recovery rate of IREO, in addition, the leach liquor along leakage pathways will also cause environmental pollution. Therefore, it is of great significance to study the deep structures and identify the leakage pathways. Our study area situates in Chang Ting county of Fujian province, which is an important rare earth deposit of China, in order to obtain high resolution deep electrical model, the electrical resistivity tomography based on multi-electrode resistivity method was used in this paper. First, we carried out multi-electrode resistivity method parameter experiment and select appropriate exploration parameters; Then, the Multi-electrode resistivity method data acquisition of 11 lines is completed by using ws-2 device mode; After that, the deep electrical structure model of the study area is obtained by inversion calculation and the thickness of the granite weathering layer (the layer containing rare earth ore) and the spatial distribution characteristics of the deep fracture structure are delineated by the deep electrical structure model of the study area. The interpretation results are consistent with the drilling results laid out in the study area. The exploration results provide important reference for the reserve evaluation of ion type rare earth mine, the sealing of leakage pathways and the layout of recovery pathways.

An application of electrical resistivity tomography to investigate leakage pathways in the exploitation of IREO
