摘要
根据灾害系统理论和风险理论,结合煤矿瓦斯爆炸特点,构建了由孕险环境、致险因子、承险体3个子系统组成的煤矿瓦斯爆炸灾害风险指标体系,通过分析2002-2012年我国瓦斯事故统计数据,采用粗糙集属性约简方法进行筛选,确定了煤矿瓦斯爆炸灾害风险评价指标体系。
According to the disaster system theory and risk theory, combined with the characteristics of coal mine gas explosion, the disaster risk assessment index system about coal mine gas explosion which is composed of the hazard - formative environment, hazard - caused factor and hazard - bearing bodies three subsystems is established. By analyzing the data of gas explosion accidents from 2002 to 2012, rough set attribute reduction method is used to determine coal mine gas explosion hazard risk index system.
