目前采空区探测的技术手段主要有地质调查、地球物理探测和钻探。对于老采空区，往往无矿产勘查资料和历史矿产开采资料，地质调查远不能准确圈定采空区范围，只能依靠地球物理探测工作来确定采空区范围、深度和边界，之后用钻探验证。对于浅部小窑采空区，目前常用电磁类方法有高密度电阻率法和地质雷达。本文通过分析高密度电阻率法和地质雷达探测采空区的成果案例，总结了浅采空区电磁异常特征。通过对比分析自然条件下地层和采空区地层的电磁场特征，研究判定采空区边界和深度的方法。

the goaf explorating is a dififcult geological disaster exploration work, determining the mined out area is an important and necessary content of the goaf exploration. At present, the technologis of detecing goaf is including geological investigation, geophysical exploration and drilling. For the old goaf, often without mineral exploration data and historical data of mineral exploitation, only rely on geophysical work to determine the mined out area scope, depth and boundary, followed by drilling veriifcation. For shallow mined out area, the high density resistivity method and ground penetrating radar is current commonly used electromagnetic method. the paper through analyse examples of shallow goaf exploration in the high density resistivity method and ground penetrating radar, to sum up the electromagnetic anomaly characteristics of shallow goaf. Through comparative analyse the electromagnetic ifeld characteristics of natural formation and goaf, to rearch the method of determinating goaf boundary and depth.
