摘　　要：针对矿山地下采空区形态、位置及分布等未知情况,结合矿山地质地形、岩层电性、开采资料,提出了一种综合探测技术,首先采用瞬变电磁法探测出采空区群分布情况,然后用三维激光扫描技术精确探测采空区形态,为矿山安全开采提供数据支撑。Combined with the geological topography and electrical properties of rock strata and mining data,a comprehensive detection technology is proposed for the unknown situation of the shape,location and distribution of the underground cavity.Firstly,the distribution of the mined out area group is detected by the transient electromagnetic method,and then the shape of the cavity is accurately detected by the three-dimensional laser scanning technology.The proposed detection technology can provide data support for safe mining.
