To enrich the effective interpretation parameters of mine transient electromagnetic method (MTEM) and improve the accuracy of detection results, based on calculating the apparent resistivity and its depth of the whole period at each moment by dichotomy, combined with induced electromotive force, advanced detection fan diagrams of the apparent resistivity and the slope of the two parameters along depth direction are drawn respectively, and the imaging results of different parameters are compared and analyzed. It is found that there is an abnormal area with good roof and floor connectivity on the left side in the front of the roadway, and the four parameters have different degrees of abnormal reflection at this position. The later advanced drilling revealed that the water inflow was 12 m3/h, which verified that the multi-parameter interpretation results of the mine transient electromagnetic method were right. The above multi-parameter interpretation method for advanced exploration of the roadway not only enriches the interpretation way of the geological body but improves the accuracy of judgment of the geological anomaly body in front of the roadway.
