錢營孜煤礦地下水動態(tài)特征及模擬研究

錢營孜煤礦地下水動態(tài)特征及模擬研究論文摘要：

地下水是錢營孜煤礦生產(chǎn)和環(huán)境保護的重要資源，在礦井的開發(fā)過程中起著至關(guān)重要的作用。本文通過對錢營孜煤礦地下水的調(diào)查和分析，對其動態(tài)特征進行了研究，并通過地下水?dāng)?shù)值模擬對該地區(qū)的水文特征進行了預(yù)測。

錢營孜煤礦地下水水位呈現(xiàn)雙峰型分布，春季和秋季是年內(nèi)水位高峰期，夏季和冬季是年內(nèi)水位低谷期。研究還發(fā)現(xiàn)，地下水水文動態(tài)與降雨量呈現(xiàn)明顯的正相關(guān)關(guān)系，相應(yīng)的，流入礦井的徑流量也隨著降雨量的增加而增加。

為了更好地預(yù)測和控制地下水的動態(tài)特征，本文使用了地下水?dāng)?shù)值模擬方法，模擬了不同場景下的地下水流動過程。結(jié)果表明，在汛期時，礦井進水流量會明顯增加，并對礦井地質(zhì)環(huán)境造成較大的沖擊效應(yīng)。然而，在合理控制礦井開采速度和水位調(diào)控策略的前提下，礦井地下水的動態(tài)特征可得到良好的控制和改善。

本文還通過研究煤礦地下水的形成機理和水文地質(zhì)特征，探討了水文環(huán)境對煤礦地下水運動和污染的影響，提出了針對該地區(qū)煤礦地下水資源保護的對策和建議。
