中文摘要： 确定突水水源是煤矿防治水的关键。相似矿区有相似的水文地质条件和水化学特征，可建立通用的突水水源识别模型。选取焦作、平顶山、郑州、潞安、鹤壁、永城、义马新安、晋城、峰峰矿区各10对矿井为研究对象，收集并检测各矿井煤层底板石炭系上段和下段薄层灰岩、奥陶系或寒武系灰岩含水层的水质资料，结合已探查的或矿井采掘过程中揭露的综合水文地质信息，分析典型矿井同一含水层在埋深、厚度、岩性、岩溶发育和构造展布等方面的相似性和差异性，研究底板灰岩含水层水化学时空变化规律。用主成分分析法分离出能代表底板灰岩含水层水化学特征的典型离子，用距离判别法建立相似矿井各含水层的识别模型，并用灰色关联度法验证模型的可靠性。比较其他华北型煤田的矿井在水文地质特征和水化学特征方面的相似性与差异性，将建立的识别模型修正后用于其他华北型煤田底板突水水源的识别中。成果可用于识别具有相似水文地质条件的华北型煤田底板的突水水源，意义重大。

英文摘要： Identifying of water inrush resource is the key of mine water preventing and controlling. Similar coalmines have similar hydrogeologic conditions and hydrogeochemical characters, so a universal identification model of floor water inrush resource can be established. Ten coal pits are chosen as objects of study from every mining area of Jiaozuo, Pingdingshan, Zhengzhou, Lu'an, Hebi, Yongcheng, Yima-Xin'an， Jincheng, and Fengfeng . Water quality of Carboniferous limestone, Ordovician and Cambrian are gathered and tested. The similitude and difference on burial depth, thickness, rock character, karst development, and structural distribution of the same water bearing layer are analysed to research the hydrogeochemical variation of floor limestone with the temporal-spatial change based on the hydrogeologic informations which are already mastered or gathered in the process of mining work. The components of ion which can represent the hydrochemical character of groundwater are extracted by use of principal component analysis. Identification model of floor water inrush resource can be established by use of distance discriminant analysis, and Grey Relevancy degree is used to test and verify the model.The similitude and difference on hydrogeologic character and hydrochemical character are researched by comparing other No
