摘　　要：矿井突水严重威胁煤矿安全生产,因此快速准确地判别突水水源对防治矿井突水灾害具有重要意义。以淮南矿区朱集东煤矿及周边井田为例,通过对132个矿井水样水化学分析和聚类分析,得出Na++K+、Ca2+、Mg2+、Cl-、HCO-3、SO2-4、pH、TDS这8个评价因子在各含水层中的统计背景值。运用模糊综合评判,将统计背景值作为评判集标准值,构建矿井突水水源判别模型。通过研究发现,模型判别结果接近于实际情况,识别效果良好,具有一定实用性和时效性,可以为今后判别突水水源提供参考。Mine water inrush is a serious threat to coal mine safety production,so it is of great significance to distinguish water inrush source quickly and accurately to prevent mine water inrush disaster.Taking Zhujidong Coal Mine and its surrounding fields in Huainan mining area as an example,through hydrochemical analysis and cluster analysis of 132 mine water samples,the statistical background values of eight evaluation factors such as Na++K+,Ca2+,Mg2+,Cl-,HCO-3,SO2-4,pH,TDS in each aquifer were obtained.Based on fuzzy comprehensive evaluation and taking statistical background value as standard value of evaluation set,the discriminant model of mine water inrush source is constructed.It is found that the discriminant result of the model is close to the actual situation,the identification effect is good,and it has certain practicality and timeliness,which can provide reference for the discrimination of water inrush sources in the future.
