摘要: 本文综合水文地质和工程地质调查结果、室内岩石力学实验,应用地下水动力学理论,改进传统的“大井法”,对条带边界下采动过程中工作面涌水量进行预测;同时,针对石嘴山矿区西翼采区特殊的地质背景,建立三维数值模型,对工作面涌水量进行预测,并结合传统涌水量预测方法和现场抽水试验结果与改进大井法所得结果进行对比,证明改进大井法对预测特殊边界条件下矿井涌水量更为精确;以期丰富采动过程中矿井涌水量的预测方法,减少水害对煤矿安全生产的威胁。

Abstract: Base on the Hydro-geological and Engineering Geology Investigation , Rock Mechanical Test , the application of theory to improve the dynamics of groundwater traditional under the border of the strip mining process to predict water, At the same time, mining for Shizuishan of the geological background, the establishment of three-dimensional numerical model to predict Water-inflow. Results show that GWM is more precise, the method of water-inflow is studied under different mining condition, with a view to the process of mining the rich mine of forecasting methods, to reduce the water hazard on the threat of coal mine production safety.
