本文以山东岱庄煤矿为研究对象，通过收集整理相关资料，采集矿区主要含水层35个水样，通过常规水质分析和同位素测试，分析矿井不同含水层地下水水化学特征，在此基础上利用数值法和解析法预测了矿井的涌水量。数值法应用有限元计算剖分法，将含水层分区参数带入有限元数值模型中，构成涌水量的计算模型，预测矿井涌水量；解析法分别以大井法、Q-S曲线法对涌水量进行计算。分析研究煤矿开采对地下水水质及水量的影响。研究表明：奥灰水水质类型均为SO4-Ca（Mg）型；太原统十三灰除8号水样外，大部分水质类型为SO4-Ca(Mg)型水；太原统十下灰含水层水质类型异常复杂，变化较大，水质类型由HCO3-Na向SO4-Ca(Mg)转变，其水质随地下水补给混合比例的不同，出现不同的过渡水质类型。矿井主要受直接顶板十下灰岩水和底板十三灰岩水、奥陶灰岩水突水的威胁，十下灰与十三灰、奥灰含水层有较大的差异，其SO42－、Ca2+、Mg2+较低，HCO3－、Na+较高，具有三个含水层中最低的矿化度。十下灰与十三灰、奥灰含水层有一定水力联系，但水力联系不强，而十三灰、奥灰含水层具有较强的水力联系。采用数值法、解析法对矿井涌水量进行计算，十下灰、十三灰水性极不均匀，且其导水性具各相异性，解析法无法模拟，涌水量计算结果取数值法计算结果，以此来研究煤矿开采对地下水水质及水量的影响。

This paper takes coal mining of Daizhuang in Shandong as an example, through collecting relevant information and taking 35 water samples from the main aquifer for general quality analysis and isotope test, groundwater hydrogeochemical characteristics of different aquifer were analyzed and aquifer quality distribution as well as migration patterns were summarized. Based on the database, mine hydraulic discharge are predicted using numerical method and analytical method, as well as the effect of groundwater quality and quantity in coal mining are studied. The study shows that the quality of Ordovician limestone are the type of SO4-Ca（Mg）, the quality of Taiyuan limestone of thirteen except the sample of the 8th are the type of SO4-Ca(Mg), and the quality of below Taiyuan limestone of ten extraordinarily complex and change more that the quality changes from the type of HCO3-Na to the type of SO4-Ca(Mg), and the water quality with the different of the groundwater recharge mixture ratio appear different type of transitional water quality. Mine is mainly affected by the direct roof of below limestone of ten and the bottom plate of limestone of thirteen as well as Ordovician limestone. There are large differences between the below limestone of ten and the limestone of Ordovician and thirteen, which have lower SO42－、Ca2+、Mg2+ and higher HCO3－、Na+ with minimum degree of mineralization in the three aquifers. The below limestone of ten and the limestone of Ordovician and thirteen have certain hydraulics connection, but the hydraulics connection is not strong, and that Ordovician limestone and the limestone of thirteen have a strong hydraulics connection. mine hydraulic discharge are used numerical method and analytical method to calculate, because the quality of the limestone of ten and thirteen are very uneven and the hydraulic conductivity is different, so analytical method can not simulate, calculations of mine hydraulic discharge only can take the calculation results of numerical method, in order to study on the effect of groundwater quality and quantity in coal mining
