ENGINEERING EXPLORATION AND STABILITY ANALYSIS OF THE TAILINGS DAM OF A LEAD-ZINC MINE

本文以某铅锌矿尾矿坝工程勘察与稳定性分析为实例,系统地介绍了以探明尾矿坝坝体及坝体周围工程地质、水文地质条件为目的的工程勘探手段和分析研究方法。在揭示了尾矿坝坝体材料空间分布状态及其力学特性的基础上,利用自动搜索的电算程序,分析计算了尾矿坝浸润线的情况和尾矿坝的整体与局部稳定性,分析计算结果与现场勘测结果基本吻合。

Taking the engineering exploration and stability analysis of the tailings dam of a lead-zinc mine as an example, this paper presents systematically the means of engineering exploration and methods used for the purpose of disclosing the geological, engineering geological and hydrogeological conditions of the dam body of a tailings dam and in its surrounding arcas. Having revealed the spatial distribution and physico-mechanical properties of the dam body materials in the railings dam ,the paper calculates and analyses the line of saturation as well as the integral and local stability of the tailings dam. The results of calculation and field exploration are essentially in agreement with each other.
