高密度电阻率法在邢台某采空区沉降评价中的应用

在前人利用高密度电阻率法探测地下采空区工作的基础上,基于采空区在沉降作用下形成的破坏＂三带＂的结构特点,依据其导电性差异,分析了利用高密度电阻率法查明采空区＂三带＂分布的可行性,并提出,利用该方法不仅可圈定出地下采空区的位置,又能查明采空区沉降评价所需＂三带＂的分布特征。实践表明,高密度电阻率法是采空区沉降评价中低耗高效,信息丰富,探测精度高的行之有效的探测技术。

Application of High Density Resistivity Method in Assessment to Settlement of Mined-Out Areas

Based on the three-zones' structural features caused by subsidence damage and their conductive differences,this paper analyzes the feasibility of high density resistivity method to detect three-zones,and proposes that the application of this method can not only delineate the location of underground mined-out areas,but also find out the distribution characteristics of three-zones.It is proved that the high density resistivity method is highly effective and low cost in assessment to settlement of mined-out ar...
