摘　　要：通过2种探测方法对某铁矿采空区进行勘探,分别对探地雷达和EH4大地电磁探测的数据收集和整理,通过对后期数据统计及图像处理分析,并结合现场中的实地情况,分析得出了本矿区地下采空区的范围分布情况和采空区的空间大小,但是EH4大地探测在本次铁矿探测中受到铁干扰的因素比较大,所以不是很准确,但经过2种探测方法的协同作用,得出了比较准确的分析结果。Exploration of the iron ore goaf through two kinds of detection methods respectively for GPR and EH4 magnetotelluric data collection and sorting, based on statistical data and image analysis, and combined with the actual situation in the field, analysis of the size distribution of the mine underground goaf and gob space, but EH4 detect the earth factors such as iron interference in the detection of iron ore is relatively large, so it is not very accurate, but the synergistic effect into two kinds of detection methods, the analysis results more accurate.
