摘　　要：为了研究朱仙庄煤矿五含水的水化学特征及离子来源,共收集了13个水样品的常规水化学组分资料。借助Aqua软件的Durov图划分出五含水的常规水化学类型,利用水化学三角图分析各常规离子的来源及水-岩相互作用,运用因子分析进一步对离子来源进行多元统计分析。研究结果表明:五含水的水化学类型以SO4-Na型为主,少数为SO4-Ca型。其化学组分主要与硫酸盐矿物溶解、碳酸盐矿物溶解、硅酸盐矿物风化以及阳离子交换作用等水文地球化学作用有关。目前,该含水层正发生以硫酸盐岩溶解为主,其他作用为辅的水-岩相互作用。In order to reveal the hydrochemical characteristics and ions source of the fifth aquifer in Zhuxianzhuang Coalmine, this paper collected 13 water samples to analyze the components of the major ions. Based on Durov diagram, the fifth aquifer were subdivided into five hydrochemistry type. Also, we analyzed the ternary diagram of hydro-chemistry to discuss the source and water-rock interaction of the major ions. Moreover, the factor analysis was carried out to confirm the ion source. The results are as follow： the main hydrochemistry type is SO4 -Na, with few of SO4 -Ca; the hydrochemical compositions are related to the effect of hydro-geochemistry, such as the dissolution of sulphate mineral, carbonate mineral, the weathering of silicate mineral and cations exchange. At present, the fifth aquifer is mainly under the dissolution of sulphate rock, along with other water-rock interaction.
