贵州水银洞金矿矿区充水因素及矿区涌水量预测

Water Filling Factors and Prediction of Groundwater Inflow in Shuiyindong Gold Deposits of Guizhou

在概述研究区的水文地质条件的基础上,分析了贵州水银洞金矿矿区充水因素,并采用集中参数法对矿区涌水量进行了预测.研究表明,下覆茅口组含水层中的地下水是矿区巷道的直接补给源,地表水和降水为间接补给源;最终矿坑涌水量预测为41 904 m3/d.

Based on an overview of the hydrogeological conditions of the study area, the water filling factors in Shuiyindong gold deposits were analyzed, and the water inflow was predicted by lumped parameter method. The study shows that the underlying the Maokou Formation 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 41 904 m^3/d.
