摘要
矿坑涌水量作为矿床疏干排水设计的主要依据,其结果的准确度直接影响矿床开采设计的合理性和安全性。露天矿坑涌水量主要受大气降水影响较大,地下水补给量较小,通过对某露天矿矿区水文地质条件和当地的气象信息分析,确定相应的计算参数,计算出该露天矿降雨迳流量,为矿山疏排工程设计提供依据。
As the main basis of dredging and drainage design of ore deposit,the accuracy of the results directly affects the rationality and safety of mining design of ore deposit.The water inflow of an open pit is mainly affected by atmospheric precipitation,and the groundwater recharge is small.By analyzing the hydrogeological conditions and local meteorological information of an open pit mine,the corresponding calculation parameters are determined,and the rainfall runoff of the open pit mine is calculated,which provides the basis for mine drainage engineering design.
