| 摘 要： | 根据煤矿开采岩层移动与覆岩破坏理论,运用地下水动力学基本原理,阐述了采动裂隙导水与采动变形压力作用使采动承压含水层水位变化的力学机制,并依此建立了采动承压含水层水位变化数学模型。结合铁煤(集团)公司大平矿三台子水库下N1S2综放开采工作面水文地质条件,通过编程计算得出工作面回采过程中白垩系下部承压含水层水位变化曲线,经与矿井水文监测系统实测数据对比,结果较为理想。

| Abstract: | According to strata movement and overlying strata failure theory of coal mining,discussed the mechanical mechanism of the water level change in confined aquifer formed by the function of crack leak water and deformation compressive stress using groundwater dynamics principle.Based on this,the mathematical model of water level change was established.Combining hydrology condition of N1S2 mind working under SANTAIZI reservoir in DAPING MINING,the changing curve of water level of confined aquifer under cretaceous during face mining was observed through programming calculation.The results are coincidence compared with the actual observation data. |
