桃园煤矿Ⅱ1042工作面主要含水层的水力联系分析

Taoyuan Coal CineⅡ1042 Face the Main Aquifer Hydraulic Connection Analysis

为了查明各含水层对桃园煤矿Ⅱ1042工作面生产的影响,对工作面各充水含水层之间的潜在水力联系进行了研究。选取工作面不同含水层共13组水样,采用水化学方法分析了各水样之间离子指标的差异,并且运用系统聚类分析对各含水层水样之间的亲密程度进行聚类。结果表明:新生界松散第四含水层和10煤顶底板砂岩裂隙水与其他含水层之间无明显的水力联系;而工作面太灰水与奥灰水的水质相似,聚类结果表明两者之间的欧氏距离最小,可归为一类,说明工作面太灰水与奥灰水具有潜在的水力联系。

In order to find out each aquifer Taoyuan Coal MineⅡ1042 working face production,the influence of the working face potential hydraulic connection between the water filling aquifers were studied.A total of 13 groups of water samples were selected from different aquifers in the working face,and the differences of ionic index among wa⁃ter samples were analyzed by hydrochemistry method,and the degree of intimacy among water samples of each aqui⁃fer was clustered by systematic clustering analysis.The results show that there is no obvious hydraulic relationship between the loose fourth aquifer in the cenozoic and the sandstone fissure water in the bottom floor of the coal roof and other aquifers.The result of clustering shows that the Euclidean distance between the two is the smallest,which can be classified into one category.It shows that the working face groundwater in the carbonic limestone and Ordovi⁃cian limestone water have potential hydraulic relations.
