摘要
针对宝日希勒露天矿开采境界内存在多个小煤窑采空区的问题,采用了以瞬变电磁为主,浅层高分辨率地震勘探为辅的综合地球物理探测方法对小窑采空区进行探测,查出采空区的位置,运用钻探手段进行验证,爆破手段进行处理,有效地查明了该矿采空区的分布,确定了采空区的大小、范围,保证安全生产。
Aiming at the problem of a number of small gob zones existing in Baorixile open-pit mining area,comprehensive geophysical method which took transient electromagnetic method as main and supplemented by shallow high-resolution seismic exploration was applied to find out the location of small gob zones.Furthermore,the drilling method and blasting method were employed to verify the detection results.Finally,the size and location of small gob zones in this open-pit mining area were accurately determined.The results are crucial importance in safe production of open-pit mining.
