摘 要：针对露天煤矿开采对地下水环境的影响，提出通过数值分析的方式对水工环境进行分析。建立矿区内地下水数值模型，然后通过地下水数值模拟计算岩溶地下水资源量，并分析矿区内岩溶地下水补给和排泄方式对露天煤矿不同时期水环境的影响。结果表明：只要合理的规划和处理，露天煤矿开采不会对地下水环境产生影响。

Abstract：Aiming at the influence of opencast coal mining on groundwater environment， the present situation analysis and simulation prediction research are carried out. The numerical model of groundwater in coal mine area is established， and the numerical simulation is corrected and the reliability is analyzed. The karst groundwater resources are calculated by numerical simulation， and the recharge and discharge modes of karst groundwater in mining area are analyzed. The influence of open-pit coal mine on water environment during construction period， operation period and service period is analyzed， and the result shows that open-pit coal mine would not affect groundwater environment as long as it has been properly planned and treated.

Key words：open pit mining; groundwater environment; numerical model; forecast analysis
