摘要(Abstract)：

地下水形成、演化过程中控制因素不同所造成的水化学组分的差异性是矿井涌水水源识别的基础,为揭示矿井主要充水含水层水化学作用及控制因素,以位于太行山东麓的典型华北型煤矿区——鹤壁矿区为研究对象,采用统计分析、Piper三线图、Gibbs图、离子相关性分析与主成分分析法对矿区122个地下水水化学资料进行了分析研究。结果表明鹤壁矿区主要充水含水层中地下水的化学组分主要受岩石的风化作用控制。奥灰水主要水化学类型为HCO_3-Ca·Mg型,水中Ca~(2+)、Mg~(2+)主要来自碳酸盐岩(方解石和白云石)的溶解。二灰水主要水化学类型为HCO_3·SO_4-Ca·Mg型或SO_4·HCO_3-Ca·Mg型,其中Ca~(2+)、Mg~(2+)、HCO_3~-的主要来源于碳酸盐岩的溶解,SO_4~(2-)来自硫酸盐岩的溶解作用和黄铁矿的氧化作用。砂岩水主要水化学类型为HCO_3-Na型,Na~+、Cl~-与HCO_3~-主要来自盐岩的溶解和硅酸盐矿物的风化作用。八灰水既有HCO_3-Ca·Mg型和HCO_3·SO_4-Ca·Mg型,也有HCO_3-Na型,Ca~(2+)、Mg~(2+)、HCO_~3-和SO_4~(2-)的来源与二灰水一致,Na~+和Cl~-可能来自盐岩的溶解作用以及砂岩水与八灰水的混合作用。
