| 摘 要： | 为研究采动影响下煤层覆岩承压含水层水位变化预测模型,根据采矿岩层移动与覆岩破坏理论,基于地下水动力学原理,建立了基于地下水稳定运动、非稳定运动两种井流方程的覆岩承压含水层水位采动变化数学模型。结合大平煤矿三台子水库下N1S2综放开采工作面水文地质条件及水文监测数据,对模型进行了验证,结果表明:采动影响下承压水的运动为非稳定运动,对应建立的数学模型能更好地拟合覆岩承压含水层水位变化。

| Abstract: | In order to predict water level change caused by mining in confined aquifer,according to the strata movement and the overlying strata failure theory of coal mining,based on the groundwater dynamics and the formulas for stable and unstable well flow of groundwater,a mathematical model to calculate the water level change was established.Combined with the measured data of hydrology condition of N1S2 coal face under Santaizi reservoir in Daping Coal Mine,the mathematical model was verified.The results showed that the mathematical model could well predict water level change caused by mining in confined aquifer. |
