三维高密度电法在尾矿库隐患检测中的应用

Application of three dimensional high-density resistivity method in hidden danger detection of tailings

三维高密度电阻率法是在二维的基础上发展起来的,克服了二维高密度电法不能直观地展示目标异常区域的走向、空间位置与形态的不足。将三维高密度电法应用于尾矿库隐患检测中,可得到丰富的地电数据,利用三维电阻率处理软件对地电数据进行反演,实现了尾矿坝三维地质数据的可视化。通过三维电阻率等值面图和三维电阻率动态截面图,可以直观、可靠的了解到尾矿坝浸润线的分布规律和坝体异常地质情况,为尾矿库的风险评估工作提供科学依据。

Three dimensional high-density resistivity method is developed on the basis of two dimensional high-den- sity resistivity method, overcoming the defect of two dimensional high-density resistivity method that can not vividly reveals the trend, spatial location and shape of target abnormal regions. Three dimensional high-density resistivity method was applied to hidden danger detection of tailings, which can get rich land resistivity data. Three dimen- sional resistivity processing software was applied to process the land resistivity data, realizing three dimensional geo- logical data of tailings dam visualization. By three dimensional resistivity iso-surface figure and three dimensional resistivity dynamic sectional figure, we can realize the distribution of saturation and the abnormal geological condi- tion of tailings dam, and provide scientific basis for the risk assessment of tailings.
