| 摘 要： | 采集了潞安矿区中部煤矿5类80份已知水源水样,利用PIPER三线图对不同来源水样水文地球化学特征进行了分析;利用聚类分析方法(Ward法)对三线图上存在重叠的砂岩水、太灰水与奥灰水进行分类,显示奥灰水与太灰水明显聚类,局部存在两者混合,砂岩水则与上述两者难以区分;最后利用Bayes模型建立了不同水源判别函数(自我检验准...

| Abstract: | This study collected and analyzed 5 types of 80 water samples from central Lu'an coal deposit to identify the hydrogeochemical characteristics by Piper Plots.The Cluster analysis method(Ward method)showed the obvious clustering and the partial mixing of ordovician limestone water and limestone water,while sandstone water was hard to separate from the other two.Bayes model was used to construct the discriminant functions of different water sources(self-test accuracy 91.5%)and to test the 19 samples of mine water inrush.12 samples from roof sandstone,4 samples from ground water and pore water and 3 samples from limestone water was then recognized.Water samples with low posterior probability(less than 80%)could indicate the mixing of the water sources. |
