The arrangement parameters including the transmitting circle, the transnussion frequency, the transmitter current, the sampling delay and the high line interference，were determined basing on the pa- rametric tests in bore holes and high-field interference region; the data treatment and inversion were deal with the combination of the field actual data and the borehole logging references. The results indicate that there is notable electric anomaly between up surrounding bed and down surrounding bed in the target area; the aquosity is relatively rich in the north of Nanyi mining area and poor in the middle and the south; F₆₆ fault and X₂₆、X₃₅、X₇₉collapse columns are mainly vertical water conduc吨of the coal seams and Onlovi-cian limestone.
