摘　　要：焦作矿区蕴藏丰富矿产的同时伴有严重的矿井水害,进行水化学特征与演化机制的分析对于预防事故的发生、地下水的保护有着重要意义。根据焦作矿区的34组水样的水化学分析结果,运用图解法、离子相关性分析法、三元混合模型和水文地球化学模拟等方法,结合焦作矿区的水文地质条件,从垂直方向上模拟分析焦作矿区的水化学演化机制。揭示了焦作矿区地下水水化学演化机制主要有:Ca^(2+)-Na^(+)阳离子交换作用;硫酸岩盐、岩盐以及碳酸盐岩等风化溶滤作用和方解石与白云石的非全等溶解作用等。为改善焦作矿区地下水环境、水资源合理开发利用提供了理论依据。Jiaozuo mining area is rich in mineral resources and is accompanied by serious mine water damage. The analysis of hydrochemical characteristics and evolution mechanism is of great significance to prevent accidents and protect groundwater. Based on the hydrochemical analysis results of 34 groups of water samples in Jiaozuo mining area, this paper simulates and analyzes the hydrochemical evolution mechanism of jiaozuo mining area from the vertical direction by using graphic method, ion correlation analysis method, ternary mixed model and hydrogeochemical simulation, combined with the hydrogeologyical conditions of Jiaozuo mining area.The mechanism of groundwater hydration evolution in Jiaozuo mining area is revealed as follows: Ca^(2+)-Na^(+)cation exchange;The weathering solubilization of sulphate salt, rock salt and carbonate rock and the inhomogeneous dissolution of calcite and dolomite. It provides theoretical basis for improving groundwater environment and rational exploitation and utilization of water resources in Jiaozuo mining area.
