| 摘 要： | 本文以丹江口水源区某磁铁矿尾矿库为例,采用高密度电法对尾矿库进行了三维电阻率结构探测,圈定了尾矿砂分布范围,实现了尾矿体三维地球物理建模,查明了尾矿库内部结构特征,通过电阻率差异圈定了4处重金属元素聚集区。验证了拟三维高密度电法在尾矿库三维结构探测中的可行性,为研究尾矿库内部污染物运移机理和污染防治提供了一种有效的技术手段。

| Abstract: | We take an iron ore tailing pond in Danjiangkou Water Source Area as an example to use high-density electrical method to detect the three-dimensional resistivity structure of tailing pond.As a result,we delineate the distribution range of tailing sand,realize the three-dimensional geophysical modeling of tailing ore body,find out the internal structure characteristics of tailing pond,and delineate four heavy metal element accumulation areas through the resistivity difference.The feasibility of quasi three-dimensional high-density electrical method in the three-dimensional structure detection of tailings pond is verified,which provides an effective technical means for the study of the mechanism of pollutant transport and pollution prevention in tailings pond. |
