利用渗透试验浅谈尾矿坝稳定性

Discussion the stability of the tailings dam using the permeability test

随着国内矿产资源大量开采和利用,在堆积尾矿废弃物时,尾矿库坝体的容积和高度在不断增加,对尾矿坝的稳定性有着很高的要求。因此,通过对矿区土样进行渗透试验,测定了不同干密度下的渗透系数,并探讨渗透试验在各种影响因素下对土体的渗透性的影响,以此判断其对坝体的稳定性。

With the abundance exploitation and utilization of domestic mineral resources when stacked tailings waste, the tailings dam in volume and height increasing,it has high requirements to the stability of the tailing dam. Therefore through the permeability test of mining area soil sample, the permeability coefficient under different dry density of soil samples are determined and penetration test are discussed in the influence of various factors on the permeability of the soil, to judge the stability of the dam.
