高密度电阻率法在某采空区勘查中的应用

Application of High-Density Resistivity Method in a Goaf Survey

摘要: 采空区的出现常常会存在一些潜在的危险，可能造成地面沉降、裂缝、建筑物基础设施等破坏。因此，为了避免采空区对地上的危害，需要进行采空区的探测工作。根据采空区与围岩层之间存在的电性差异，利用高密度电阻率法基本查明了采空区的位置、埋深及分布范围。结果表明，高密度电阻率法是采空区调查评价中的一种行之有效的探测方法。

Abstract: The emergence of goafs often has some potential hazards, which may cause ground subsidence, cracks, and damage to buildings and infrastructure. Therefore, in order to avoid the hazards of the goaf to the ground, it is necessary to carry out the detection of the goaf. According to the electrical difference between the goaf area and the surrounding rock, the location, buried depth and distribution range of the goaf area were basically found out using the high-density electrical method. The results show that the high-density resistivity method is an effective detection method in the survey and evaluation of goafs.
