| 摘 要： | 在皖北矿区采取了2 2个深层地下水水样,测试Ag、Al、As、Ba等2 0种微量元素,建立了主成分分析模型。根据元素相关性、特征值与累计方差贡献率,进行了地下水的微量元素主成分分析和地下水主成分解释。在此基础上建立了皖北矿区主要突水水源4个主成分的判别表达式,从而得出结论:矿区地下水,特别是四含、太灰与奥灰3个突水含水层微量元素的质量浓度与4个主成分息息相关,可以简单地把第一、二、三、四主成分概括为地下水的溶滤作用、越流作用、河流补给作用、构造裂隙补给作用。

| Abstract: | Twenty-two water samples of deep-seated groundwater were taken in the mining area in northern Anhui to test twenty kinds of trace elements such as Ag、Al、As、Ba and so on. The major constituent analytical model was established, meanwhile the trace elements major constituent analysis and the major constituent interpretation for groundwater were performed according to the element correlation, the eigenvalue and the progressive total variance contributing rate. On the basis of this, four major constituents discriminants were developed for the main gushing water sources in the mining area in northern Anhui. It concluded that the groundwater in the mining area especially for the the content of the trace elements in the fourth aquifer, the Taiyuan limestone aquifer and the Ordovician limestone aquifer have related to the four major constituents. The first, the second, the third and the fourth major constituent can be simply generalized the lixiviation, the process of the leakage, the feeder action of river and the tectonic fracture respectively. |
