The Taiyuan formation limestone water in the Huaibei coalfield is not only the water source for coal mining, but also the water source for industry and agriculture in mining areas. Its hydrogeochemical characteristics and water quality are generally concerning. In this paper, conventional ion tests were carried out on the Taiyuan formation limestone water of 16 coal mines in the Sunan and Linhuan mining areas of the Huaibei coalfield. Piper trigram, Gibbs diagram and an ion scale coefficient map were used to analyze the hydrogeochemical characteristics of the Taiyuan formation limestone water. The water quality was evaluated in a fuzzy comprehensive manner. The results show that the main cation and anion contents in the Taiyuan formation limestone water were Na > Mg > Ca > K, SO > HCO > Cl. There were differences in the hydrogeochemical types of the Taiyuan formation limestone water in the two mining areas; HCO-Na type water was dominant in the Sunan mining area and SO·Cl-Na type water was dominant in the Linhuan mining area. The chemical composition of the Taiyuan formation limestone water is mainly affected by the weathering of the rock and is related to the dissolution of the evaporated salt and the weathering of the silicate. The fuzzy comprehensive evaluation results show that the V-type water accounts for a large proportion of the Taiyuan formation limestone water in the study area and the water quality is poor. This study provides a basis for the development and utilization of the Taiyuan formation limestone water and water environmental protection in the future.
淮北煤田太原组灰岩水不仅是采煤的水源，也是矿区工业和农业的水源。其水文地球化学特征和水质普遍令人关注。本文对淮北煤田孙疃、临涣矿区 16 对矿井太原组灰岩水进行了常规离子测试，采用 Piper 三角图、Gibbs 图和离子标度系数图分析了太原组灰岩水的水文地球化学特征，并采用模糊综合评判法对水质进行了评价。结果表明，太原组灰岩水中主要阳离子和阴离子含量为 Na > Mg > Ca > K，SO > HCO > Cl。两个矿区太原组灰岩水的水化学类型存在差异，孙疃矿区以 HCO-Na 型水为主，临涣矿区以 SO·Cl-Na 型水为主。太原组灰岩水的化学成分主要受岩石风化的影响，与蒸发盐的溶解和硅酸盐的风化有关。模糊综合评价结果表明，研究区太原组灰岩水以 V 型水为主，水质较差。本研究为太原组灰岩水的开发利用和未来水环境保护提供了依据。
