摘　　要：在地质勘探中,TEM法体积效应影响小,探测深度大,对低阻反映灵敏,因此,其作为一种物探手段,已被广泛应用于地球物理勘探的各个领域。TEM法在煤矿突水巷道勘探中,曲线形态为高电位单峰异常,这个特征用于煤矿充水巷道探测准确度高,效果明显。In the geological exploration,TEM method has properties:small influence of volume effect,and large depth of probe,and there is sensitive reaction for low impedance,so that it has already used widely into each field of geophysical prospecting,as one kind of geophysical prospecting means.TEM method used to search water bursting drift of coal mine,the shape of curve showing single peak abnormalism of high electric potential,thereby make accuracy of search much higher and there are clear effect.
