摘　　要：通过改善数据处理,可以有效提高瞬变电磁法在煤矿采空积水探测中的应用效果。以内蒙古某煤矿采空区积水探测项目为例,通过将采空塌陷区“三带”的空间展布及电性特征纳入到地电模型的构建、充分利用已有地质和测井资料构建层状地电模型、使用澳大利亚EMIT公司的Maxwell软件数据处理平台中的正、反演模块等方法,达到了改善数据处理、提高瞬变电磁法在煤矿采空积水探测中的应用效果,完成了层状介质条件下煤矿采空区积水范围的圈定工作。研究表明,在数据处理与解释中,具有基础资料分析全面、初始地电模型简单可靠、正反演计算准确、采空积水区低阻特征明显等优点。探测成果在煤矿生产工作中起到了一定的指引作用。In this paper, the water detection project of a coal mine in Inner Mongolia is taken as an example in order to improve the application effect of TEM in water accumulation area detection. The forward and inverse modules of the Maxwell data processing platform of Australia EMIT Company are used to delineate the water area of the stratified medium in the coal mine. In the data processing and interpretation, the basic data analysis is comprehensive, the initial geoelectric model is simple and reliable, the forward and inverse calculation is also accurate, and the low-resistivity characteristics of the mining water area are obvious. The detection result plays a certain guiding role in the coal mining production.
