国内很多大型露天煤矿面临着先前存留的小煤矿采空区的困扰，给露天矿带来了很严重的安全隐患。首次采用瞬变电磁法、钻探和三维激光扫描相结合的综合探测技术对平朔东露天矿群采空区进行了探测研究，提高了综合探测精度，查明了该矿内群采空区的分布范围、埋深、空腔形状、大小、走向等。为平朔东露天矿填补了关于地下采空区的详细资料，也为矿山正常生产提供了安全保障。

Many large-scale open-pit coal mines are faced with the puzzle of small mine goafs retained previously,it brings very serious potential safety hazard for open-pit coal mines. For the first time,the composite detection technology by combining transient electromagnetic method, drilling and three-dimensional laser scanner was applied to detect and research the group goafs in east Pingshuo open-pit mine,the composite technology improved the detecting precision,and found out the distribution range,burial depth,cavity shape,size and strike direction of group goafs. This research supplemented many details to group goafs in east Pingshuo open-pit mine, and provided safety guarantee for regular mining production.
