摘要
尾矿库作为矿山中最大的危险源之一,极易引发泥石流、滑坡和溃坝等地质灾害。造成尾矿库灾害的因素多样,针对尾矿库风险因素的不确定性等问题,本文采用因子分析方法对尾矿库风险指标进行评价。根据尾矿库灾难成因及特点,结合相关工程实际,确定库容、坝高等十项风险指标,建立因子分析风险评价模型,对各因子进行定量分析,确定主要风险成因,明确因子间的相互关系,为尾矿库风险控制提供参考。分析结果表明主矿种、附属矿种、库容和坝高是引起尾矿库风险的主要因素。
Tailings reservoir is one of the biggest hazard sources in mine,which can easily lead to geological disasters such as debris flow,landslide,dam-break and so on. The factors that caused the disaster of tailings reservoir were various,and aiming at the uncertainty of risk factors for the tailings reservoir,the article used the factor analysis method to evaluate risk for the tailings indicators. According to causes and characteristics of tailings dam disaster,the paper combined with engineering practice,determined the ten risk indicators such as reservoir storage and established the height of dam,factor analysis risk assessment model,for the quantitative analysis of each factor,determining the main causes of risk,clearing the relationship among the factors,and as the risk of the tailings control to provide a reference. The analysis results showed that the main minerals,minerals,reservoir storage and the height of dam were the main factors of causing the risk of tailings reservoir.
