钱营孜煤矿地下水动态特征及模拟研究

钱营孜煤矿地下水动态特征及模拟研究论文摘要：

地下水是钱营孜煤矿生产和环境保护的重要资源，在矿井的开发过程中起着至关重要的作用。本文通过对钱营孜煤矿地下水的调查和分析，对其动态特征进行了研究，并通过地下水数值模拟对该地区的水文特征进行了预测。

钱营孜煤矿地下水水位呈现双峰型分布，春季和秋季是年内水位高峰期，夏季和冬季是年内水位低谷期。研究还发现，地下水水文动态与降雨量呈现明显的正相关关系，相应的，流入矿井的径流量也随着降雨量的增加而增加。

为了更好地预测和控制地下水的动态特征，本文使用了地下水数值模拟方法，模拟了不同场景下的地下水流动过程。结果表明，在汛期时，矿井进水流量会明显增加，并对矿井地质环境造成较大的冲击效应。然而，在合理控制矿井开采速度和水位调控策略的前提下，矿井地下水的动态特征可得到良好的控制和改善。

本文还通过研究煤矿地下水的形成机理和水文地质特征，探讨了水文环境对煤矿地下水运动和污染的影响，提出了针对该地区煤矿地下水资源保护的对策和建议。
