摘要
先前存留的采空区给露天煤矿带来了巨大的安全隐患。为了查清某大型露天矿采空区赋存情况,首次采用瞬变电磁法对该矿进行了探测研究。结果表明,绝大部分揭露空区的钻孔均位于高阻异常区域;经矿方现场钻探验证,瞬变电磁法取得了比较理想的解译成果,具有较高的准确性,为露天矿安全生产提供了保障。
If a open-pit mine exists a lot of goafs, it will be a huge hidden danger. To survey accurrence state of goaf in a large open-pit mine, the transient electromagnetic method was used to detect the mine first. The detection indicated that most of drillings which expose the goaf were located in the area of high resistivity anomalies; The interpretation result of transient electromagnetic method applied in open-pit mine was reasonable and accurate after drilling to verify accuracy of the method by the mine. The transient electromagnetic method offered security for the open-pit mine during the mining process.
