呼吉尔特矿区葫芦素煤矿水文地球化学特征研究

Research on Hydrogeochemical Characteristics in Hulusu Coal Mine of Hujierte Coal Field

摘要: 为了弄清葫芦素煤矿各含水层的水文地球化学特征，特别是对主采煤层（2-1煤）存在水害影响的侏罗系含水层，利用各含水层中水化学数据开展了相关研究，结果表明：葫芦素井田内，各含水层可划分为第四系松散孔隙含水层、白垩系孔隙裂隙含水层和侏罗系砂岩裂隙含水层，水体中矿化度自上而下逐渐增加，从<500 mg/L逐渐增至5 700~7 800 mg/L，水化学类型变化过程为HCO₃-Ca·Mg型→HCO₃-Na型→SO₄-Na型→SO₄·Cl-Na型。

Abstract: In order to make clear the hydrogeochemical characteristics of each aquifer, especially for the main mining seam (2-1 coal) Jurassic aquifer influenced by water disasters in Hulusu Coal Mine, hydrogeochemical data of each aquifer was used to carry out reach. The results showed that the groundwater system of Hulusu Coal Mine could be divided into three main solid systems. These aquifer systems were as follows: Quaternary unconsolidated rock porous aquifer, Cretaceous porous-fractured aquifer and Jurassic sandstone fracture aquifer. There was a positive correlation between the concentration of total dissolved solid (TDS) and the depth of aquifer. The concentration of TDS increased from <500 mg/L to 5 700 to 7 800 mg/L gradually, and the processes of water chemistry type were as follows: HCO₃-Ca·Mg→HCO₃-Na→SO₄-Na→SO₄·Cl-Na.
