摘　　要：露天采场涌水量预测是矿山开采的重要资料,也是矿山水文地质工作中最复杂而且最重要的任务之一,它决定矿床能否开采以及开采的方法和手段的选择。因此,矿山水文地质人员对于露天采场的涌水量计算方法必须加以研究。露天采场涌水量的计算公式很多,本文分别计算正常降雨时和设计频率暴雨量时的露天采场的涌水量。对矿坑涌水量预算结果进行修约,并对计算精度进行评价。The prediction of water inflow in open pit is not only an important data of mining,but also one of the most complex and important tasks in mine hydrogeology.It determines whether the deposit can be mined and the choice of mining methods and means.Therefore,the calculation method of water inrush in open pit must be studied by mine hydrogeologists.There are many formulas for calculating the water inflow of open pit.In this paper,the water inflow of open pit is calculated under normal rainfall and design frequency rainstorm respectively.The budget result of mine water inflow is revised and the calculation accuracy is evaluated.
