摘要: 为研究顾北矿区地下水水化学特征及其控制因素，快速准确判别矿区突水水源提供依据。采用常规数理统计、Piper三线图、相关性分析、TDS与各离子关系图、Gibbs图以及离子比例系数6种方法对研究区地下水22个水样进行系统的研究分析。结果表明：研究区内含水层总体上呈弱碱性；阳离子以K++Na+为主，阴离子以Cl-为主，HCO3-和SO42-次之；新生界下含和煤层顶板砂岩水质类型为Cl-Na+K型，底板砂岩水质类型为Cl·HCO3-Na+K型，太灰和奥灰含水层水质类型Cl·HCO3-Na+K·Ca型和SO4·HCO3-Ca型；地下水水化学性质受水岩相互作用的影响。Abstract: In order to study the hydrochemical characteristics and control factors of groundwater in Gubei Mining Area, to quickly and accurately provide basis for distinguishing mine water inrush sources, in this paper, the conventional mathematical statistics, Piper diagram, correlation analysis, TDS and diagram, Gibbs diagram and the ions ratio coefficient six kinds of methods of groundwater are used to systematically study and analyze 22 water samples from the study area. The results show that the aquifer is generally weakly alkaline; K+ and Na+ were the main cations in the groundwater with Cl- being occupied anionic, HCO3- and SO42- second; hydrochemistry type of Cenozoic group and roof sandstone of coal mine was Cl-Na+K, floor sandstone was Cl·HCO3-Na+K, the water chemistry types of Taiyuan and Ordovician limestone were Cl·HCO3-Na+K·Ca and SO4·HCO3-Ca. The water chemistry of groundwater was influenced by the interaction of water and rock.
