煤矿瓦斯爆炸危险因素定量评价方法研究及应用

Research and Application of Quantitative Evaluation Method of Coal Mine Gas Explosion Risk Factors

以苏北煤业为工程背景,采用事故树分析方法中的最小割集和最小径集定量分析法,对煤矿瓦斯爆炸危险因素进行定量分析,阐述了事故树定量分析的基本原理和主要分析步骤;构建了苏村煤业的矿井瓦斯爆炸事故树,事故树共包含130组最小割集和6组最小径集,依据最小割集和最小径集的概念,揭示了苏村煤业发生瓦斯爆炸的可能途径,并提出了相应的预防措施。

Taking the northern Jiangsu coal industry as the engineering background,the quantitative analysis method of minimum cut set and minimum path set offault tree analysis method is adopted to quantitatively analyze the risk factors of coal mine gas explosion,and the basic principle and main analysis steps offault tree quantitative analysis are expounded;The fault treeof gas explosion in Sucun coal mine is constructed.The fault tree includes 130 groups of minimum cut sets and 6 groups of minimum diameter sets.According to the concepts of minimum cut sets and minimum diameter sets,the possible ways of gas explosion in Sucun coal mine are revealed,and the corresponding preventive measures are put forward.
