摘　　要：根据鄂尔多斯市东胜区某矿地质地形特征,分析了该区域的采空区地球物理特征:不积水采空区一般表现为高阻异常,顶板富水及积水采空区则表现为低阻异常,对该矿1134、1136、1138工作面采用瞬变电磁法与高密度电法综合勘探方法,发现1处高阻异常区、2处低阻异常区,基本查明了采空区的位置、分布范围和顶板富水情况。According to the geological and topographic characteristics of Erdos Dongsheng District, geophysical characteristics of this area were analysed ： anhydrous goaf is generally performed for high resistivity,roof water rich and mined-out area with accumulated water show low resistance anomaly. 1134,1136,1138 working face in coal mine were explored by combined utilization of transient electromagnetic method and the high density resistivity method, one high resistivity anomaly area and two low resistivity anomaly areas were found, the location and range of underlying mined-out area and the roof water conditions were also identified.
