基于FTA-AHP的矿山爆破飞石伤人事故风险分析

Risk Analysis on the Mine Blasting Fly-rock Injury Accidents Based on FTA-AHP

应用FTA-AHP分析法对矿山爆破飞石伤人事故进行风险分析,通过建立爆破飞石伤人事故树,根据FTA构建递阶层次结构模型,引入事故树分析中的基本事件结构重要度的大小比值来构造判断矩阵,计算得出各基本事件的重要度排序。对比FTA分析法,此方法可以将各基本事件对顶上事件的影响程度更好的区分,以便有效地预防和控制该类事故的发生。

The FTA-AHP method is used to analyze the mine blasting fly-rock injury accidents, the blasting fly-rock injury accident tree is built, according to the FTA method, the hierarchical model is con- strueted, the judgment matrix is obtained by introducting the ratio of structure importance of basic events in FTA method, so, the order of each basic events is caeulated. Compared with the FTA method, the FTA-AHP method is capable of distinguishing the influence degree of each basic event to the top event so as to prevent and control the occurrence of the accidents more effectively.
