内蒙古东胜煤田矿井水水质特征与水环境评价

以中国内蒙古东胜煤田的矿井水为研究对象,以地球化学、煤化学、矿井地质学、水文地质学等学科为理论指导,在现场地质调研的基础上针对性地采集水样,并通过仪器对矿井水的pH值、总硬度、SO42-、Cl-及HCO3-进行测试评价,对水质的化验结果进行了分析。结合矿井水评价方法,利用灰色聚类法,以总硬度、Cl-、SO42-三项因素作为评价指标,通过建立水质数学模型,进行统计计算,定量化的实现对东胜煤田矿井水环境的评价。结果表明：东胜煤田的矿井水水质属于中等-较好型,优良型地下水占39%,Ⅲ型地下水占44%,因此东胜煤田的矿井水为Ⅲ型地下水环境。

Mine water quality characteristics and water environment evaluation of Inner Mongolia Dongsheng coal field

Taking Inner Mongolia Dongsheng coal field as research object,guided by geochemistry,coal chemistry,mine geology,hydrogeology and so on,collect water samples pertinently,then test its pH value,total hardness,SO42-,Cl-and HCO3-concentration.Analyse the assay results of water quality on the basis of field geological investigations.Combining the evaluation methods for mine water with water quality mathematical models,made statistics and calculations with grey clustering method,through the evaluation index of three factors including total hardness,Cl-and SO42-.The results show that,the mine water quality of Dongsheng coal field is middle-better type,good underground water cover 39 percent and Ⅲ-type underground water cover 44 percent,it is Ⅲ-type underground water environment.
