基于正态模糊数的矿井煤尘爆炸危险度分析

摘要

利用事故树分析法对矿井煤尘爆炸事故进行分析,采用3σ表征法对事故基本事件的发生概率进行处理,同时应用正态模糊数对确定基本事件的重要度进行排序,把导致矿井煤尘爆炸的因素进行分级,找出发生概率比较大的基本事件,从而找到预防煤尘爆炸事故发生的途径.%The fault tree analysis method was applied to analyze the mine coal dust explosion.The 3σ expression method was applied to handle the occurrence probability of the accident.Meanwhile the normal fuzzy function was applied to set up the sequence of the important degree for the basic events.The factors to cause the mine coal dust explosion were classified.The basic events with a high occurrence probability were sought.Therefore the access to prevent and control the mine coal dust explosion accidents was sought.
