In this paper, the hydrogeological characteristics in the southern coalfields of China are first briefly outlined. Then, taking the Meitanba mine as an example, the evolution and modeling of mine water inflow are studied. Finally, the hazard characteristics related to mine water and mud inrush are analyzed. The results show that the main mine water sources in the Meitanba mine area are groundwater, surface water and precipitation. The evolution of mine water inflow with time indicates that the water inflow is closely related to the development of karst structures, the amount of water from rainfall infiltration, and the scope of groundwater depression cone. The mine water inflow increases with time due to the increase in mining depth and the expansion of groundwater depression cone. Using the big well method and following the potential superposition principle, a hydrogeological model considering multi-well interactions has been developed to predict the mine water inflow. Based on the monitored data in the Meitanba mine area over a period of nearly 60 years, it is found that with increasing mining depth, the number of water and mud inrush points tended to decrease. However, the average water and mud flow rate per point tended to increase.

本文首先简要概述了我国南方煤田的水文地质特征。然后，以美潭坝矿为例，研究了矿井进水的演化和建模。最后，分析了矿井突水和突泥的危害特征。结果表明，湄潭坝矿区主要矿井水源为地下水、地表水和降水。矿井进水量随时间的演化表明，进水量与岩溶构造的发育、降雨入渗的水量、地下水凹陷锥的范围密切相关。由于开采深度的增加和地下水的膨胀，矿井进水量随时间增加 凹陷锥。采用大井法，遵循电位叠加原理，建立了考虑多井相互作用的水文地质模型，用于预测矿井进水量。根据湄潭坝矿区近60年的监测数据发现，随着开采深度的增加，突水突泥点数量呈减少趋势。然而，每点的平均水和泥浆流速趋于增加。
