摘 要：針對露天煤礦開采對地下水環(huán)境的影響，提出通過數(shù)值分析的方式對水工環(huán)境進行分析。建立礦區(qū)內(nèi)地下水?dāng)?shù)值模型，然后通過地下水?dāng)?shù)值模擬計算巖溶地下水資源量，并分析礦區(qū)內(nèi)巖溶地下水補給和排泄方式對露天煤礦不同時期水環(huán)境的影響。結(jié)果表明：只要合理的規(guī)劃和處理，露天煤礦開采不會對地下水環(huán)境產(chǎn)生影響。

關(guān)鍵詞：煤礦開采;地下水環(huán)境;數(shù)值模型;預(yù)測分析

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
