摘　　要：利用峰峰五矿的突水资料进行了矿区地下水数值模拟和矿井涌水量预测。首先,根据水文地质条件,建立矿区地下水渗流的数学模型。然后,运用突水资料对模型进行检验,模型检验中各观测孔的实测水位与模拟水位拟合较好。最后,利用所建模型进行矿坑涌水量预测,结果表明,-100m水平以下煤层的开采,矿坑涌水量大,开采成本较高。Numerical simulation of groundwater flow and prediction of drainage in the No. 5 mine of the Fengfeng coal mine area are presented in this paper, using the data from a water invasion. A mathematical model of groundwater flow is built on the basis of the analyses of the hydrogeological conditions. The model is verified with the water invasion data. The measured and simulated water levels fit well during the model verification. The mine drainage is predicted using the established model. The results indicate that the coal mining below - 100 m will result in a large amount of drainage and relative high cost.
