摘　　要：内蒙古赤峰地区广泛分布着铅锌矿资源,铅锌矿被大量开采后遗留的采空区,严重威胁着人民生命及财产安全,制约着当地社会经济发展。该文介绍了采用瞬变电磁法对采空区进行勘察,得到视电阻率反演拟断面图;利用金维软件将反演数据整合处理,绘制出不同标高的平面等值图,最后划分异常位置及分布范围。所圈定的平面异常进行了钻探验证,验证结果与瞬变电磁法推断解译结果吻合度较高。说明瞬变电磁法在该铅锌矿采空区探测具有实用性和可靠性,值得推广应用。Lead-zinc mine resources are widely distributed in Chifeng of Inner Mongolia.Goaf of lead-zinc mine which is being exploited in large quantities seriously threatens to the safety of people s lives and properties,and restricts the local social and economic development.In this paper,the transient electromagnetic method is used to explore the goaf mine area,and the inversion fitting profile of resistivity is obtained.The inversion data are integrated and processed by using Jinwei software,and the planar contour profile of different elevations are drawn.The anomaly locations and distribution ranges are delineated.The delineated plane anomalies are verified by drilling,and the verification results are in good agreement with the predicting interpretation results of transient electromagnetic method.It shows that transient electromagnetic method is practical and reliable in the goaf detection of lead-zinc mining area,which is worth popularizing and applying.
