摘　　要：为了解淮北煤田中层水化学演化过程,选择淮北煤田较具代表性的宿临矿区为研究基地,以历史监测水质数据为基础,采用离子组合比以及主成分分析等方法,分时段开展中层水水文地球化学时空演化特征分析。研究结果表明,宿临矿区中层水水化学类型主要是HCO_(3)·SO_(4)—Na·Mg型和HCO_(3)—Na·Mg型,短期内无明显变化。离子组合比和主成分分析结果显示,中层水常规离子组分主要受硅酸盐风化作用的影响,也伴有离子交换作用。主成分得分等值线图显示整个研究区中层水浓缩作用和阳离子交替吸附作用较稳定。中层水TDS等值线分析表明西部中层水相对东部而言,水流速度较快,滞留时间长。研究结果为矿区水源地实现科学管理提供一定的参考。In order to understand the chemical evolution process of mid-layer water in Huaibei coalfield,the representative mining area,namely Sulin mining area,was selected as the research base.Based on the historical monitoring water quality data,the ion combination ratio method and principal component analysis method and so on were used to analyze the temporal and spatial evolution characteristics of mid-layer water in four time periods,so as to explore the water-rock interaction types and the temporal and spatial evolution of mid-layer water flow field in the study area.The results showed that the hydrochemical types of mid-layer water were mainly HCO_(3)·SO_(4)—Na·Mg and HCO_(3)—Na·Mg,and there was no significant change in the short term.The ion combination ratio and principal component analysis suggested that the conventional ion components of mid-layer water were mainly affected by silicate weathering,and also accompanied by ion exchange.Contour map of principal component scores showed that the concentration and cation alternating adsorption of mid-layer water were stable in the whole study area.The TDS isoline analysis of the mid-layer water suggested that water flow velocity in the west was faster than that in the east,and detention time in the west was longer than that in the east.The research results will provide some references for scientific management of water source in the mining area.
