摘要
根据煤矿事故的特点,在对多种风险评价方法优缺点分析的基础上,重点对概率风险评价方法进行了研究,充实、完善并规范了概率风险评价方法的评价内容、计算公式和评价过程,在某煤矿1371工作面进行了实践,结果表明,煤矿瓦斯概率风险评价能使管理者对危险状况有较为直观的了解,从而及时构建出各工作面的危险评估计划表,对矿井瓦斯危险情况进行科学预测和控制。
According to the characteristics of coal mine accidents,the probabilistic risk assessment was studied,based on the analysis of merits and faults of different risk assessment methods.The assessment content,computational formulas and assessment process were enriched,improved and standardized.The probabilistic risk assessment was applied to No.1371 working face in a coal mine.The results showed that this assessment method could help the managers to judge the hazard level and build the risk assessment charts for different working faces in time so as to scientifically forecast and control the gas risk in coal mines.
