摘　　要：快速准确的判别矿井突水水源对煤矿安全开采而言是至关重要的。通过对张集矿水文地质资料的研究,并在此基础上根据不同含水层中水化学离子成分不同的特性,选用Ca^2+、Mg^2+、K^++Na^+、HCO^-3、SO4^2-、Cl^-六大常规离子,且增加pH和总溶解固体(total dissolved solids,TDS)共8个因素作为判别因子,基于Fisher判别法和质心距分析理论,利用SPSS软件,建立对张集矿突水水源判别的函数模型,并对随机抽取的8个水样进行判别分析。结果表明:因子分析对模型训练样本的建立具有一定的有效性;增加判别因子后,样本误判率降低,准确率从90.625%提高到96.875%;由于构造条件等因素的影响,待判水样存在一定的误差。因建立函数模型方法简单,且准确率较高,对突水水源类型的判别具有可行性。It is very important for safe mining to distinguish the water source of mine water inrush quickly and accurately. Based on the study of hydrogeological data of the Zhangji Coal Mine in Huainan, East China, and according to the different characteristics of hydrochemical ions in different aquifers, ions Ca^2+, Mg^2+, K^++Na^+, HCO3^-, SO4^2-, and Cl^-, plus pH value and TDS(total dissolved solids) were used as the discriminant factors. Using the Fisher discriminant method and centroid distance analysis, the discrimination model of the water inrush source in the Zhangji Mine was established with SPSS software. Eight water samples were randomly collected for analysis. Results show that the factor analysis was effective for the establishment of model training samples. Increasing the number of discriminant factors could reduce the rate of wrong discrimination of samples, and the rate of correct discrimination was boosted from 90.625% to 96.875%. However, due to the influence of local structural conditions and other factors, certain errors was inevitable in the discrimination. The function model is easy to establish with accurate results, and is practical to distinguish the type of water inrush source.
