中文摘要：

为了对未知采空区进行勘察,消除安全隐患,简要介绍了EH-4电磁成像系统的原理和工作方法,并利用EH-4电磁成像系统进行了舒兰市明珠佳苑二期采空区边界勘探。通过大地电阻率反演断面色谱图分析确定了该地区采空区的分布范围,为矿区地面建筑场地的稳定性和完整性评价提供参考。研究结果表明：EH-4技术在勘测煤矿采空区中取得了良好的效果,这也为以后的采空区探测提供了一种可靠手段。

英文摘要：

In order to make a survey in the unknown goaf of the mine to eliminate the safety hidden dangers.Principle and working method of EH-4 electron-agnetic imaging system were briefly introduced in the paper.And it was used in exploration of goal edge for Mingzhu park second stage.Then,goal distribution range was obtained by analysis of inversion section chromatogram of earth resistivity,provide evaluation of stability and integrity for the ground construction site of mine lot.The results shows that EH-4 system got good results in exploration of goal edge,and could provide a reliable means for the future survey in the goal.
