摘要
顾桥煤矿二叠系砂岩裂隙水是煤层开采的直接充水水源,为了对其进行科学防治,文章收集130个水样分析资料,利用Piper三线图、Gibbs图、离子比值法、因子分析与聚类分析方法,对其水化学特征及形成作用进行系统分析。统计分析与相关分析结果表明,顾桥煤矿二叠系砂岩裂隙含水层主要水化学类型为HCO_(3)·Cl-Na+K型。离子比值法和Gibbs图分析结果显示:砂岩裂隙水中Na^(+)主要来源于岩盐和其他钠盐的溶解;Cl^(-)主要来源于岩盐的溶解,且在地下水长期演化过程中,发生了阳离子交替吸附作用及脱硫酸作用,使得Ca^(2+)、Mg^(2+)、SO_(4)^(2-)含量减少,Na^(+)和HCO_(3)^(-)含量增加。因子分析结果与离子比值法分析结果一致,聚类分析结果进一步证实上述形成作用。
The Permian sandstone fissure water in Guqiao Coal Mine is the direct water filling source for coal seam mining.In order to carry out scientific prevention,this paper collected 130 water sample analysis data,and systematically analyzed its hydrochemical characteristics and formation by using Piper diagram,Gibbs diagram,ion ratio method,factor analysis and cluster analysis.The results of statistical analysis and correlation analysis show that the main hydrochemistry type of the Permian sandstone fissure aquifer in Guqiao Coal Mine is HCO_(3)·Cl-Na+K.The results of ion ratio method and Gibbs diagram analysis show that Na^(+)in the sandstone fissure aquifer mainly comes from the dissolution of rock salt and other sodium salts;Cl^(-)mainly originates from the dissolution of rock salt,and during the long-term evolution of groundwater,cation exchange and adsorption and desulfurization occurred,resulting in a decrease in Ca^(2+),Mg^(2+),SO_(4)^(2-)content,and an increase in Na^(+)and HCO_(3)^(-)content.The results of factor analysis are consistent with those of ion ratio analysis,and the results of cluster analysis further confirm the formation.
