摘要
为快速有效评价矿井瓦斯的危险程度,准确鉴别预防煤矿瓦斯事故的相对薄弱环节,以引发煤矿瓦斯事故的众多因素为基础,构建了煤矿瓦斯危险性的灰熵综合评价模型;以均衡接近度为主要评价指标,利用宁夏某煤矿瓦斯事故各影响因素原始数据进行分析。评价结果表明,该模型能够合理客观地对煤矿瓦斯危险性进行评价。
In order to evaluate the danger degree of mine gas rapidly and effectively,differentiate the relative weak link of prevention of coal mine gas accident accurately, the grey entropy comprehensive evaluation model of mine gas hazard was constructed based on the numerous factors of gas accidents in Coal Mine. With the balanced adjacent degree as the main evaluation index, raw data of gas acci- dent affecting factors were analysed by the example of a coal mine in Ningxia province. The evaluation results indicate that,this model can evaluate coal gas risk reasonably and objectively.
