摘　　要：随着不断开采,紫金山矿区水文地质条件和工程地质条件发生了复杂变化。通过对露天开采前后地形地表及地下水变化规律的分析,初步探究矿区水文地质条件的变化特点。结果表明,矿区地下硐室巷道纵横穿插,地下巷道作为地下水的排泄通道交叉重叠,使得地下水动态变化明显。提出全盘统筹建立地下水长期观测系统,以期为类似工程提供一定的参考。With the continuous mining,the hydrogeological conditions and engineering geological conditions of Zijinshan mining area have undergone complex changes.The changed characteristics of the hy⁃drogeological conditions in the mining area are preliminarily explored through the analysis of the change law of the terrain surface and groundwater before and after open-pit mining.The results show that the under⁃ground tunnels in the mining area are interspersed with each other,and the underground tunnels are overlap⁃ping as the drainage channels of groundwater,which makes the dynamic changes of groundwater obvious.The results show that the underground tunnels in the mining area are interspersed with each other,and the underground tunnels are overlapping as the drainage channels of groundwater,which makes the dynamic changes of groundwater obvious.A long-term groundwater observation system is proposed to provide some reference for similar projects.
