Measurement parameter extreme distance: AB=30m, BM0=20m, MN=10m

Compared with the actual relative distance, the groundwater concentration area of the spectrum induced polarization method is roughly the same as that of high density electric method, but the lateral resolution of the spectrum induced polarization method is high, while the high density resistivity method is poor in transverse resolution, shallow and less information, so the guidance hole position given by the spectrum induced polarization method is more suitable.
