摘要
为了研究回坡底煤矿奥陶系灰岩含水层的水文地质特征,采用地下水化学动力学和水文地球化学基本理论,对奥陶系灰岩含水层的水文地质、水动力学和水化学特征进行定性分析和定量评价,为回坡底煤矿制定科学合理的防治水措施提供依据。研究表明,坡底煤矿奥陶系灰岩含水层由南向北水质类型变化依次为SO_(4)·HCO_(3)-Ca·Mg→HCO_(3)·SO_(4)-Na·Ca→HCO_(3)-Ca·Mg→SO_(4)·Cl-Ca·Mg;研究区南部及东部含水层埋藏较浅,透水性较强,地下水径流较快,岩溶较发育;中部波浪状条带范围内岩溶比较发育,形成一中等的地下水径流带;北部及西北部含水层埋藏较深,透水性较弱,地下水径流缓慢,岩溶不发育。
In order to study the hydrogeological characteristics of the Ordovician limestone aquifer in Huipodi Mine,the hydrogeological,hydrodynamic and hydrochemical characteristics of the Ordovician limestone aquifer were qualitatively analyzed and quantitatively evaluated by using the basic theories of underground water chemical kinetics and hydrogeochemistry,which provided a basis for the formulation of scientific and reasonable water prevention and control measures in Huipodi Mine.The research showed that the change of water quality type of Ordovician limestone aquifer in Podi Mine from south to north was SO_(4)·HCO_(3)-Ca·Mg→HCO_(3)·SO_(4)-Na·Ca→HCO_(3)-Ca·Mg→SO_(4)·Cl-Ca·Mg.The aquifers in the south and east of the study area were shallow,the permeability was strong,the underground water runoff was fast,and the karst was more developed.Karst was relatively developed in the middle wavy strip,forming a medium underground water runoff zone;the northern and northwestern aquifers were buried deep,the permeability was weak,the underground water runoff was slow,and the karst was not developed.
