摘　　要：瞬变电磁法是建立在电磁感应原理基础上的探测方法,通过激发、接收电磁探测信号,形成电场耦合圈,当电流发出后,遇到不同的导电介质会形成不同的涡流场,通过涡流场分析赋水情况。记录了铂龙煤矿0901采空区的探测过程、数据处理及结果解释,得出采空区冒落泥岩层赋水情况,为今后类似地质条件的水文地质勘探提供一定的指导意义。Transient electromagnetic method is a detection method based on the principle of electromagnetic induction.By stimulating and receiving electromagnetic detection signals,an electric field coupling loop is formed.When current is emitted,different conductive media will form different eddy current fields,and the water accumulation situation will be analyzed through the eddy current field.The exploration process,data processing,and interpretation of the results of the 0901 goaf in the Bailong Coal Mine are recorded,and the water occurrence of the caving mudstone layer in the goaf is obtained.This provides certain guidance for hydrogeological exploration under similar geological conditions in the future.
