研究开采影响下地下水动态特征是进行矿井水文地质条件实时研究、科学防治矿井水害及合理开采的重要基础。选取煤5顶板含水层为代表，分析1998~2009年以来24个水样的Na+、Ca2+、Mg2+、Cl-、SO42-、HCO3-、NO3-、矿化度及 pH 值大小变化，结果表明含水层水化学特征稳定，动态不明显。因此，选取1950-2009年各时段内不同含水层水样113个，进行水化学特征聚类分析，得出4组典型分类：第四系冲积层孔隙承压水及煤5顶板(A 段、B 段)水；煤5-煤7、煤12-1顶底板水；煤12-2、煤14、K3及G层水；奥陶系石灰岩岩溶水；分类与含水层水文地质循环特征相符。研究结果对整个东欢坨矿区的防治水工作具有一定意义。

During the long-term production of mine,a large number of water gushing and drainage lead to conspicuous change to groundwater dynamic.It's an important basis to study the characteristics of groundw-ater under the influence of rational exploitation and hydrogeological geology.Selecting the roof of the 5 th coal seam as the representative aquifer,analyzed the content of Na+,Ca2+,Mg2+,Cl-,SO4 2-,HCO3-,NO3-, salinity and pH value on 24 water samples since 1998 to 2009,the results show that the chemical character-istics of the aquifer water is stable,and the dynamic is not obvious.Therefore,1 1 3 chemical samples in dif-ferent aquifer water are used for water chemical cluster analysis.Obtained 4 typical classification groups:Water from quaternary alluvium pore confined aquifer and roof of coal 5 aquifer;Water from coal 5-7,coal 12-1 aquifer;Water from coal 12-2,coal 14,K3 and G aquifer;Water from ordovician limestone aquifer.The classification and characteristic of hydrological geology match well.
