灰色关联度在矿井突水水源判别中的应用

Application of grey correlation degree in the identification of sources of mine water bursting

以灰色理论为基础,利用灰色关联度方法对矿井潜在突水水源的水质情况与突水水样进行多变量关联分析与计算,并通过工程实例进行取样验证,计算结果表明,该矿大青灰岩含水层的3个取样点关联度最高,说明大青灰岩水与矿井突水水样的关系密切,由此可以判定突水水源是大青灰岩含水层,通过进一步的分析与验证,突水水样为大青水的判断是可靠的。

Based on the grey theory and with the application of the method of grey correlation degree,a multi-variant correlation analysis and computation are carried out on water samples to probe the water quality of potential bursting water in coal mines.Sampling and verification are carried out through a certain project as an actual case.Results of the computation show that the three water sampling points in the mine located in Daqing limestone aquifer strata have the highest correlation degrees,indicating water from Daqing limestone is closely related with the water sampled from the bursting water.Thus it is proved that the bursting water does come from Daqing limestone aquifer.Further analysis and verification indicates the determination is reliable that the bursting water samples do come from Daqing limestone aquifer.
