基于灰色关联法的上隅角瓦斯积聚因素主次性分析

On the primary and secondary degrees of gas collection of top corner: Based on gray integrated assessment method

采煤工作面上隅角瓦斯积聚因素控制是一个复杂的灰色系统工程,其影响因素、关联变量和约束条件复杂.应用灰色关联分析方法,对影响上隅角瓦斯积聚的关键因素进行归一化处理,通过建立灰色综合评价模型,得出影响上隅角瓦斯积聚的因素关联序.经实例分析表明:用灰色关联综合方法评价上隅角瓦斯积聚各控制因素的主次性更加有效、合理.

The gas collection factors control of coal mining top corner is a complex gray system engineering due to influential factors, on relation variables and constraining conditions. This paper has united the key factors of impacting top corner gas collection by using the gray relation analysis method, and arranged the influential factors of gas collection of top corner in order by estimating gray integrated assessment method. It is shown that the method of integrated analysis of gray collection is an effective and objective method in estimating the primary and secondary degrees of the controlled factors of top corner＇s gas collection.
