Abstract: In order to eliminate the effect of metal facilities in the roadway on mine transient electromagnetic surveying，take trail interference sources for example，the transient electromagnetic response characteristics were analyzed by method of field experiment，with different distance，direction and modes between the wire-frame and tracks.It showed that the induction electromotive force amplitude increased under the influence of the tracks，and there was great difference of the response characteristics obtained in different condition.By calculating the induction electromotive force ratio of different time windows in interference and non-interference environment，the correction method of fitting function was proposed，and was used to correct the disturbed data of practical engineering.The results show that the fitting function correcting method can remove the abnormal interference in disturbed data，and better reflect the feature of abnormalities in coal seam roof，improving the detection accuracy of water anomaly by method of mine transient electromagnetic survey.
