摘要
在前人研究的基础上,应用数理统计原理对矿井瓦斯浓度进行了分析,提出了"矿井稀释瓦斯能力合理度","采掘面稀释瓦斯能力合理度",采用隶属函数确定评价指标值,运用改进的层次法确定评价指标的权重,建立了通风系统合理性评价模型。通过对实际矿井通风系统的合理性评价,取得了良好的应用效果。
Based on the previous work,analysis is done on mine gas concentration by using the theory of mathematical statistics,the rationality of the capacity of mine diluting gas and working face diluting gas are put forward.And also,evaluation indicator values is confirmed by adopt membership function and the weights of evaluation indicator is confirmed by applying the improved analytic hierarchical method,model of the reasonable assessment of mine ventilation system is build.Through the reasonable assessment of actual mine ventilation system,a good apply effect is obtained.
