摘　　要：根据火烧区煤岩层中富水岩性的不同地质特征,采用瞬变电磁法对火烧区煤岩回采工作面顶板进行探测,结合井下的地质资料判断是否出现富水区域。结果表明,矿井瞬变电磁法能有效圈定出火烧区下伏煤层工作面顶板富水性的位置和范围,探测结果与钻探验证结果基本吻合,为煤矿安全生产提供技术依据。According to different geological characteristics of water abundance in coal strata lithology, the transient electromagnetic method is adopted to advance on roof detection, combined with geological data to determine whether there is a rich underground water area,then take measures in advance to avoid the accident of the major water disasters. The results show that the mine transient electromagnetic method can effectively detect the location and range of the working face roof water content and scope, provide the basis for water drain.
