中文摘要：

建立高承压含水层数学模型，识别其参数特征，是预报不同开采方案下该含水层水量合理疏放大小的依据。在分析潘北煤矿地质及水文地质条件基础上，利用-490 m水平4个阶段放水试验成果资料，利用Modflow建立了A组煤层底板灰岩水渗流水文地质模型及其数值模型，经识别和验证后，获得了太原组灰岩含水层水文地质参数，并结合“突水系数”，分别预报了-490 m和-650 m水平在确保A组煤层安全开采下的疏放量，其计算结果，给太原组灰岩水的防治提供了决策依据。

英文摘要：

Based on analyzing the hydrogeological conditions and the data from discharge test of different stages at-490 m level, numerical simulation model and hydrogeological conceptual model have been built about limestone aquifer discharge under the bottom of seams group A through software Visual Modflow. After identification and verification, hydrogeological parameters of limestone aquifer in Taiyuan Formation were obtained, and in com-bination with coefficient of inrush water, dewatering volume at level -490 m and -650 m was calculated respec-tively under the condition of assuring mining safely. Mining production indicates that the calculation results con-form to actual situation and also provide reference for control of limestone water inrush.
