摘要
针对尾矿库事故产生的复杂性、多样性及不确定性等特点,在众多尾矿库事故调查的基础上,分析得到主要危险源为塔管隧结构破坏,建立WBS-RBS与故障树耦合的风险评估方法。进一步将危险源引入到WBS-RBS结构中,构造工作分解结构(WBS)、风险分解结构(RBS)及二者耦合矩阵,综合分析各项事故风险因素。采用故障树分析法对塔管隧结构破坏事故进行敏感性分析,计算敏感系数和风险因素重要度排序,有针对性的提出风险应对建议与举措。
In view of the complexity,diversity and uncertainty of tailings reservoir accidents,this paper establishes a risk assessment method based on the coupling of WBS-RBS and fault tree.Based on the investigation of tailings reservoir accidents,the main hazard sources are analyzed and introduced into the WBS-RBS structure.Work breakdown structure(WBS),risk sub-structure(RBS)and their coupling moments are constructed to conduct comprehensive analysis of various accident risk factors.Fault tree analysis method is used to analyze the sensitivity of statistical tower-tube-tunnel mechanism damage accidents,calculate the sensitivity coefficient and risk factor importance ranking,and some risk response suggestions are put forward.
