高密度电法和等值反磁通瞬变电磁法在临武县矿区采空区勘查中的应用

Application of High Density Electricity Method and Equivalent Reverse Flux Transient Electromagnetic Method in Exploration of Mined-out Areas in Linwu County

在修建临武县工业大道过程中,遇到采矿巷道口,为查明工业大道下采空区的分布,本文采用高密度电法和等值反磁通瞬变电磁法对采空区分布范围及埋深进行了勘查,最终确定公路下矿层采空区的空间展布,为公路前期设计、治理提供了依据.

In the process of building Linwu Industrial Avenue,the mining roadway entrance is encountered.In order to find out the distribution of goaf under the industrial Avenue,high density electrical method and equivalent inverse magnetic flux transient electromagnetic method are used to survey the distribution range and buried depth of goaf,and finally the spatial distribution of goaf under the highway is determined,which is in front of the highway.The period design and management provide the basis.
