摘　　要：通过对范各庄矿的水文地质概况进行前期调研和勘查,结合水质化验数据,总结其矿井水化学特征。范各庄矿水文地质条件复杂,突水水源主要分为6类。从数据库中选取30个典型的代表水样作为水化学样本,绘制出各主要含水层的常规离子浓度对比图和各主要含水层的特征离子饼状图。结合两图分析得出范各庄矿主要含水层的化学性质和特征离子,最后通过Piper三线图验证其结论的正确性。为范各庄矿突水水源准确、高效判别提供了依据。Through the preliminary investigation and exploration of the hydrogeological situation of Fangezhuang Mine,the chemical characteristics of mine water were summarized by combining with the water quality test data.The hydrogeological conditions of Fangezhuang Mine were complex,and the water inrush sources were mainly divided into six categories.Thirty typical representative water samples were selected from the database as the hydrochemical samples of this study,and the conventional ion concentration comparison diagram of each main aquifer and the characteristic ion pie chart of each main aquifer were drawn.The chemical properties and characteristic ions of the main aquifers in Fangezhuang Mine were obtained by combining with the analysis of the two diagrams.Finally,the correctness of the conclusion was verified by the Piper three-line diagram.A basis for accurate and efficient identification of water inrush sources in Fangezhuang Mine were provided.
