尾矿库溃坝事故风险因素分析

Analysis on Risk Factors of Tailings Dam Failures

针对尾矿库溃坝事故,选用国内外历史尾矿库溃坝事故数据,利用非线性回归分析方法,通过建立一系列的关系函数,对影响尾矿库溃坝后果的主要因素进行分析,确定了尾矿库溃坝事故的风险因素为尾矿库的坝高和容积.在尾矿库的建设、运行过程中,要重点加强对尾矿库的坝高和容积的限制,减少尾矿库潜在溃坝风险.

The accidents of tailings dam failures are one of the most serious abrupt environmental pollution accidents in the world.This paper chose worldwide historical data on tailings dam failures as analysis data,and by developing a series of relational functions,the main factors influencing the results of tailings dam failures were analyzed based on nonlinear regress analysis.Research result found that,the key risk factors influencing tailings dam failures are the height of tailings dam and the volume of the tailings reservoir.When designing,building or operating a tailings reservoir,the height of tailings dam and the volume of the tailings reservoir must be limited,so as to reduce the potential risk of tailings dam failure.
