摘要
基于三类危险源理论,对导致煤矿瓦斯爆炸事故发生的危险源进行分析,构建了该类事故危险源风险评价指标体系。通过四种常用标度的比较分析,最终采用一致性较好的9/9-9/1标度,运用层次分析法(AHP)构造判断矩阵,并采用Matlab数值计算准确确定各指标权值。根据各层次指标权重比较,得出导致瓦斯爆炸事故发生的重要因素及其相互关系,为矿井生产过程中该类事故的防治提供了可靠的理论依据。
Based on the 3- type hazard theory,the hazards of coal mine gas explosion were analyzed and the index system of risk evaluation was established. Through comparison of four common scales,the 9 /9- 9 /1 scale was selected for better consistency,the judgment matrix was structured using AHP,and each index weight value was determined accurately with MATLAB. And according to the comparison of the weight values,the key factors of gas explosion accidents and their mutual relations were concluded.
