摘　　要：文章以淮南市顾北矿及其周边煤矿的地下水水质资料为基础,采用改进的地理信息系统(geographic information system,GIS)三维空间插值方法构建顾北矿新生界下部含水层的真三维地下水水化学场,并利用Tecplot可视化软件实现其三维可视化。研究结果表明,该方法可以有效描述地下水水化学场的三维空间分布规律并成功实现其三维可视化,特别对于水质空间分布连续性较好的含水层,描述准确性较高,对具有统一地下水位的地下水含水层具有较好普适性,可为矿井地下水水质真三维空间分布规律研究和矿井水害防治等提供重要辅助决策支持。Based on hydrogeological data of Gubei coal mine in Huainan City and its neighbor coal mines,real 3D groundwater chemical field of the Cenozoic underpart aquifers in Gubei coal mine was built with improved geographic information system(GIS)3D spatial interpolation,and 3D visualization of the field was realized by using Tecplot software.The result shows that the presented method can effectively represent the 3D spatial distribution of groundwater chemical field and realize its 3D visualization.The chemical field model has high accuracy for the spatial distribution of water quality of the aquifers with good spatial continuity and is applicable to groundwater aquifer with a unified water table.The model can provide significant decision support for the study of 3D spatial distribution of groundwater quality and the prevention and treatment of groundwater in mines.
