摘要
论述了邢台煤矿放水试验中的水质变化特征，并根据地球化学原理，利用指标组合、水质图像分析方法，把试验区水质分为典型奥灰水和大青水，大青水又分为三种情形，而且计算出各混合水中奥灰水的比例，从而得出该矿三个水文地质单元的富水地段及其补给源和补给强度。
This paper deals with the water quality change during dewatering test in Xingtai Coal Mine. According to geochemical theory, the mine water is divided into two types of water quality which one is ordivician karst water and another is Daqing karst water, by using index composition, water quality map analysis method. Daqing karst water can be divided intothree types according to water quality too. The paper also calculates the proportion of Ordivician karst water in mixed one,therefore, points out the water rich areas in the mine and it's recharge source and quantity.
