金属矿山地下水流动规律及涌水量预测数值模拟研究

Numerical Simulation of Groundwater Flow Law and Water Inflow Prediction in Metal Mines

矿山地下水流动规律及涌水量预测是地下矿山生产过程中的一项重要工作,因受矿区水文地质条件以及地下水水源等复杂系统的影响,传统理论和经验公式计算得出的结果往往不够直观且与实际相差较大。从数值模拟角度探讨矿山地下水流动规律和涌水量预测,结合实际矿山案例采用FEFLOW软件建立真三维地下水分析模型并开展多工况分析,得到了不同情形下的矿区地下水分布规律和涌水量值,可为矿山实际生产防排水工程提供指导。同时,该方法可在其它金属矿山地下水研究中推广应用。

Groundwater flow law and water inflow prediction is a vital work in underground mine production process.As the complex and systematic influence of hydrogeological conditions and groundwater sources,the results calculated by traditional theoretical and empirical formula are always nonintuitive and with great difference from reality.In this paper,the groundwater flow law and water inflow prediction of underground mines are investigated with numerical simulation method and linked with a real mine case.Based on FEFLOW software,a true three-dimensional groundwater analysis model is built and groundwater flow laws and water inflow values are obtained for different conditions,which could be an effective guidance for waterproof and drainage works in mine production process.Meanwhile,this method could be applied to other underground metal mines for groundwater research.
