摘要
在概述研究区水文地质条件的基础上,分析了贵州丰乐铁矿矿床充水因素,并采用大井法对矿区涌水量进行了预测.研究认为,上覆和下伏含水层中的地下水是矿区的直接补给源,地表水和大气降雨为间接补给源;矿坑总涌水量预测为1 829.90 m3/d.
Based on an overview of the hydrogeological conditions of the study area, the water filling factors in Fengle iron deposits were analyzed, and the water inflow was predicted by large well method. The study shows that the groundwater in aquifers overlying and underlying the mine layer is the direct recharge source of groundwater inflow, and surface water and rainfall are indirect recharge sources. The total inflow of mining area is 1 829.90 m3/d.
