摘要
运用灰色系统理论对牛西矿多个出水点的水样中主要离子含量的数据进行多变量关联分析,得到透水点水样与桑干河水样的关联度值较大。而地面直流电测深探测结果显示,桑干河地下150m处有一由南向北的水流运移通道。因此判定南翼9370地区顶板含水层水源来自地表桑干河,桑干河河水通过补给髫髻山组安山岩二段含水层,水经采空后形成的顶板冒裂带透入到工作面。
The multivariate correlative analysis of the grey system theory was applied to deal with the data of the main ion contents of the multivariate water outlets in the Niuxi mine.The result shows that the correlation degree is relatively high between the permeable water sample and the river water sample of Sanggan river.And according to the consequence of the geophysical prospecting,there is a flow migration channel from the south to the north,which is about 150 meters under the ground of the north bank of Sanggan river.It is almost certain that the water source of roof aquifer in 9370 working face in Southwing is from the river of Sanggan,which supplies the andesite aquifer of Tiaoji Mountain Group,and penetrates into the working face along the roof fracture zone after the mining.
