平顶山矿区矿井突(涌)水水源判别模式

IDENTIFICATION MODEL OF GUSHING WATER SOURCES IN PINGDINGSHAN COAL MINES

摘要: 对在平顶山矿区所采集的地下水样品进行了多元统计分析,以识别一些来源不清的样品归属,建立该区突(涌)水水源判别模型。选择水中6大离子为变量,对37个水样进行了Q型聚类分析和阳离子三角形分析;以聚类分析所得的结果为基础,应用判别分析方法建立了该矿区寒武系灰岩水、薄层灰岩水(L₂)和砂岩水3类判别模型,并应用马氏距离作F检验和归属概率"检验",结果表明所建立的判别模型是有效的。

Abstract: The samples of groundwater chemistry collected at Pingdingshan Coal Mine were analyzed geostatistically to identify from which apuifer(s) the water originate(s),and to set up an identification model of gushing water sources.Taking six major ions of groundwater as variables,the cluster analysis and Piper diagram analysis were done for 37 water samples.Based on the results of the two methods above mentioned,the discriminative analysis was used to obtain the identification model of gushing water sources,and the model is proved to be effective through F test and "attribution probability" test.
