摘　　要：以某煤矿6-1采区为研究案例,根据采区地质水文及地球物理电性特征情况,合理在采取内容实施数据采集,对数据实施预处理后,从全域视电阻率断面图和全域视电阻率切面图2个角度实施煤矿老窑采空区积水探测分析。根据分析结果对采取1#和2#煤层采空区积水范围进行综合解释说明,最后采用钻孔探测法进行采取采空区积水情况验证分析,有效确认瞬变电磁法的应用价值。Taking the 6-1 mining area of a certain coal mine as a research case,based on the geological,hydrological,and geophysical electrical characteristics of the mining area,data collection is reasonably carried out through content selection.After preprocessing the data,water accumulation detection and analysis in the goaf of the old coal mine are carried out from two perspectives:the overall apparent resistivity cross-sectional map and the overall apparent resistivity cross-sectional map.Based on the analysis results,a comprehensive explanation of the water accumulation range in the goaf of the No.1 and No.2 coal seams was provided.Finally,the borehole detection method was used to verify and analyze the water accumulation situation in the goaf,effectively confirming the application value of the transient electromagnetic method.
