【摘要】：在研究煤矿区地质、水文地质及采矿条件等的基础上,采用Visual MODFLOW进行煤层开采弱透水层厚度变化对上覆松散含水层影响的数值模拟研究。结果表明:在模拟期间,松散含水层地下水位下降幅度随着弱透水层厚度增大逐渐减小。研究成果为煤矿区松散含水层地下水保护提供了依据。
[Abstract]:On the basis of studying the geology, hydrogeology and mining conditions of coal mining area, Visual MODFLOW is used to simulate the influence of the thickness of weak permeable layer in coal seam mining on the overlying loose aquifer. The results show that the decrease of groundwater level in the loose aquifer decreases with the increase of the thickness of the weak permeable layer during the simulation period. The research results provide the basis for groundwater protection of loose aquifer in coal mine area.
