摘　　要：使用PROTEM67D瞬变电磁勘探系统,在山西临汾西部某煤矿采空区探测工作中,选择合适的工作装置,通过科学的试验,确定合适的工作参数。依据对局部已知采空区的瞬变电磁的电性特征的分析,建立适合划分本区采空区的视电阻率数值变化范围的解释方法,对整个勘探区的电性断面图进行分析解释,从而圈定了全区的采空区和采空积水区的范围,并且取得了良好的地质效果。In the detection of the mined-out area in a coal mine of western Linfen, the author used the PROTEM67D transient electro-magnetic exploration system, selected suitable work facilities and, through scientific experiment, determined the appropriate work pa-rameters. According to an analysis of the transient electromagnetic electric characteristics of the local known mined-out area, the inter-pretation method was established for the apparent resistivity variation range suitable for the division of the mined-out area, the analysis and interpretation of the electric character sectional drawing for the whole exploration area were conducted and, on such a basis, the limits of the mined-out area and the mined-out waterlogged area were delineated. It is proved that the geological effects are satisfactory.
