陕北煤炭基地萨拉乌苏组含水层的特征

Salawusu formation aquifer characteristics in the coal base of northern Shaanxi

萨拉乌苏组是陕北煤炭基地最主要的含水层。该含水层富水性不均匀,总体上富水性中等到强;地下水水质良好,循环途径短,受煤矿开采影响明显,采煤过程中应该做好含水层结构保护。

Sarawusu formation is the main aquifer in the coal base of northern Shaanxi. The water abundance of this aquifer is uneven,which is medium to strong. The groundwater quality is good and the water circulation route is short. In order to prevent the influence of coal mining,the aquifer structure should be well protected in the process of coal mining.
