Water disaster is one of the most important factor affecting coal mine safety production,which affect not only regular production but also cause casualties often occurs in mine excavation.So conducting the study on the distribution of the water in front of the roadway in mine excavation has important significance for mine driving and production safely.The TEM is an important geophysical prospecting method in the exploration of the tunnel because of its sensitivity to the change of the resistivity,and it is more sensitive than other methods.First of all,based on the whole space below Fuxin mine geological strata background noise simulation calculation,get the whole space below Fuxin mine background response curve.After the Shanxi city of Linfen province China Fuxin coal mine 10201 working face with auxiliary transport crossheading of three groups of transient electromagnetic detection,with Fuxin mine background response curve correction of the measured data,and use the corrected result of advance detection of geological prediction of the transient electromagnetic,on this basis,through the actual results revealed to verify the detection results,prediction results after calibration data obtained proved more accurate.Therefore,the transient electromagnetic exploration as an important geophysical method in advanced detection,using geophysical data after correction can be more accurate inversion analysis of water distribution,through the verification accuracy analysis of this method can be verified,the mine safety production provides a powerful guarantee.
