摘　　要：采空区严重威胁着地面建筑物和矿山的安全,对采空区探测方法的研究有着重大的现实意义.本文探讨了探地雷达及EH-4电导率成像法对某露天钼矿采空区探测的方法技术及其应用效果.探地雷达对浅层地段不仅有很高的探测精度和高分辨率,能达到对浅部采空区的精确定位.EH-4电导率成像系统的探测深度大,通过电阻率断面图的局部异常体,可以直观的来判断采空区的位置从而查明深部采空区,结合二者对采空区进行综合探测.Goafs, the waste part after mining, seriously threaten the building and mining area, so it has a real meaning to research the measures for exploration of goafs. The paper introduces the application of ground penetrating radar and EH-4 to the exploration of goaf. The ground penetrating radar has accurate detective precision and high distinguishability, and then, could determine the exact position of superficial goafs. EH-4 could explore deep part and identify the deep collecting space area. Combining the two techniques we can make comprehensive exploration to goafs.
