在系统分析煤矿瓦斯爆炸灾害影响因素的基础上,针对影响因素的复杂性及其之间存在相互作用的特点,提出了煤矿瓦斯爆炸灾害态势评估的GRA-ANP-FCE模型。该模型采用灰色关联分析方法计算影响因素的灰色关联度并进行排序,以获得煤矿瓦斯爆炸灾害的主控因素,构建了由主控因素组成的煤矿瓦斯爆炸灾害态势评估指标体系,采用网络分析法建立了多准则、多层次的评估指标体系网络模型并计算了各评估指标权重,结合评估指标的权重分布,采用多级模糊综合评判法对煤矿瓦斯爆炸灾害的态势进行了评估。通过实例验证了该方法的合理性。
Based on the systematic analysis of the influencing factors of gas explosion in coal mine, a GRA-ANP-FCE model for gas explosion hazard assessment of coal mine is put forward in view of the complexity of the influencing factors and the interaction between them. The model uses gray relational analysis method to calculate and rank the gray relational degree of influencing factors to get the main control factors of gas explosion disaster in coal mine and construct the evaluation index system of gas explosion disaster in coal mine which is composed of main controlling factors. A multi-criteria and multi-level evaluation index system network model is established and the weight of each evaluation index is calculated. Based on the weight distribution of evaluation indexes, multi-level fuzzy comprehensive evaluation method is used to evaluate the situation of gas explosion disaster in coal mine. The rationality of this method is verified by an example.
