摘要
本文以磁选铁矿尾砂为研究对象,通过分析水利行业关于各类泥石流的研究成果,结合尾砂粒径和尾砂堆放特点,提出一个专适用于矿山尾矿库的溃坝影响分析方法,可对尾矿库溃坝影响进行定量分析,并计算泄砂总量、溃口宽度、坝址处最大流量、洪水传播时间、流速、淤积厚度、冲击力等重要参数,为矿库溃坝影响分析及防治工作提供依据。结果表明提出的矿山尾矿库溃坝影响分析方法可以对尾矿库溃坝造成的泥石流影响进行评估,从而确定其影响范围,影响程度,预先做好防灾措施,并在工程中得到了有效应用。
In this paper,the tailings of magnetic separation iron ore is taken as the research object,through the analysis of the research results of various types of debris flow in the water conservancy industry,combined with the particle size of tailings and the characteristics of tailings stacking,a dam break impact analysis method is proposed,which is specially suitable for the mine tailings pond,and can quantitatively analyze the dam break impact of tailings pond,and calculate the total amount of sand discharge,the width of the dam break,the maximum flow at the dam site,the width of the dam break,the width of the dam break Flood propagation time,flow velocity,sedimentation thickness,impact force and other important parameters provide the basis for dam break impact analysis and prevention work.The results show that the proposed method can be used to evaluate the impact of debris flow caused by tailings dam break,so as to determine the scope and extent of the impact,take preventive measures in advance,and has been effectively applied in the project.
