Influenced by seasonal rainfall, the total groundwater inflow at the bottom of open-pit mines exhibits seasonal fluctuations. However, effective methods are lacking for forecasting groundwater inflow because groundwater inflow mechanisms remain unclear, thus hindering targeted seasonal adjustments of drainage measures. Consequently, the drainage capacity may be underutilized and emergency response capabilities may be insufficient. Addressing the aforementioned issues, this study investigated the intrinsic relationship between rainfall and groundwater inflow using seasonal time series analysis and proposes a groundwater inflow prediction model, aiming to explore the inherent correlation between precipitation and runoff. Moreover, seasonal adjustment strategies for drainage measures were explored. The proposed model can enhance the economic viability of drainage projects while ensuring safety. It addresses the key challenge of adapting measures to seasonal variations and provides a conceptual framework for optimizing drainage measures in open-pit mining.

受季节性降雨影响，露天矿底部地下水流入总量呈现季节性波动。然而，由于地下水流入机制尚不清楚，缺乏有效的地下水流入预测方法，从而阻碍了排水措施的针对性季节调整。因此，排水能力可能未得到充分利用，应急响应能力可能不足。针对上述问题，本研究利用季节性时间序列分析研究降雨与地下水流入量之间的内在关系，并提出地下水流入量预测模型，旨在探讨降水与径流之间的内在相关性。此外，还探讨了排水措施的季节调整策略。所提出的模型可以在确保安全的同时增强排水工程的经济可行性。它解决了适应季节变化的措施的关键挑战，并为优化露天采矿排水措施提供了概念框架。
