Abstract：In order to study the influence of the support using bolt and wire mesh on the mine transient electromagnetic detection, physical simulation experiment and mine test were carried out according to the similarity criterion of physical simulation, the transient electromagnetic response characteristics and law under support using bolt and wire mesh were studied, and the correction method was proposed. The actual application results indicated that under the influence of the support using bolt and wire mesh, the measured secondary induction potential value increased obviously, the inverted apparent resistivity value decreased significantly, and its influence on the induction signal at the early stage was greater than that at the later stage. In addition, mathematical model for transient electromagnetic detection correction under support using bolt and wire mesh was built and a new data processing method was proposed, which can effectively remove the false anomalous and improve the accuracy of data inversion interpretation.
