焦作矿区地下水水化学特征及涌水水源判别的FDA模型

运用统计学Fisher判别分析(FDA)理论，根据含水层涌水水样的水化学分析结果，建立焦作矿区涌水水源的数学识别模型，分析了矿区地下水水化学特征及形成机制，确定了含水层涌水的补给来源，并对它们进行判别分析及结果验证。结果表明:FDA模型预测涌水水源与常规水化学方法分析结果基本一致；矿区奥灰水补给太灰水特征明显，煤层顶板砂岩水与深部岩溶水联系较弱。FDA模型利用回代估计法所得到的误判率小，适用性强，简易方便，具有较强的涌水水源判别能力。 

The chemical features of ground water and FDA model used to distinguish source of water burst in Jiaozuo mine area

Using the Fisher Discrimination Analysis Theory(FDA),and according to the analysis results of the water sample,the authors establish the mathematical recognition model of the source of water burst in the Jiaozuo mining area and do its discriminatory analysis and result verification.Using synthetic water chemical analytical method and the FDA model discriminatory analytical method of the source of water,and analyzing chemical char-acteristic of groundwater and forming mechanism in the mining area,the authors...
