摘　　要：矿井水害严重制约着矿井的生产,确定涌水来源对矿井安全生产具有重要的现实意义。以水银洞金矿斜井近地表井壁为研究对象,在分析涌水机理的基础上,采用模糊综合判别法和灰色关联度理论,结合6项水化学指标进行矿井涌水来源识别。利用判别模型对各水样数据进行分析处理,通过隶属关系及关联度分析判断,得出涌水水源为大气降水。涌水机理分析结果表明,斜井近地表井壁导水通道主要为裂隙带,主要涌水水源为大气降水;水银洞金矿水文地质条件较为复杂,采用常规水化学特征结合判别模型判别涌水来源,有效避免了判断结果不准确甚至误判的情况发生,有利于快速、经济、准确地判别出涌水水源。研究成果可为类似条件下矿井井筒涌水水源判别与矿井水害防治提供理论依据。The mine water disaster seriously restricts the production of the mine.It is of great practical significance to determine the source of the water inrush for the safe production of the mine.Taking the near-surface wall of inclined shaft in Shuiyindong Gold Mine as the research object,on the basis of analyzing the mechanism of water inrush,the fuzzy comprehensive discriminant method and grey correlation degree theory were used to identify the source of mine water inrush combined with six hydrochemical indexes.The discriminant model was used to analyze and process the data of each water sample.Through the analysis and judgment of membership relationship and correlation degree,it is concluded that the source of the inrush water is atmospheric precipitation.By analyzing the mechanism of water inrush,it is found that the water channel of the near-surface wall in inclined shaft is mainly the fracture zone,and the main source of water inrush is atmospheric precipitation.The hydrogeological conditions of this mine are relatively complex.The method using conventional hydrochemical characteristics combined with the discriminant model to identify the source of the water inrush can effectively avoid the occurrence of inaccurate or even misjudgment of the judgment results,and is conducive to the rapid,economic and accurate identification for the source of the water inrush.The research results provide a theoretical basis for the source identification of water inrush in mine shaft as well as the prevention and control of mine water disaster under similar conditions.
