闭坑矿井地下水污染及其防治技术探讨

近年来,随着我国闭坑矿井数量的逐渐增加,闭坑后的矿区地下水环境问题日益突出。通过研究矿井闭坑产生的一系列水文地质效应,如含水介质条件、储水结构、地下水动力场、地下水化学场等的变化,阐明了矿井闭坑带来的地下水污染问题。根据地下水的埋深不同,初步将污染划分为浅层和深层污染两大类,由于污染模式的成因不同,又进一步对每类污染做了亚分类,并重点分析了各类污染的形成机制。最后结合国内外已有的地下水污染防治技术,针对闭坑矿井提出了防治地下水污染的措施。

Discussion on Groundwater Pollution Caused by Abandoned Mines and Its Controlling Techniques

In recent years,as the number of abandoned mines increasing in China,the environmental problems of groundwater in closed mines are becoming more and more prominent.A series of hydrogeologic effects affected by mine closure were studied,including the changes of water-bearing media condition,water storage structure,hydrodynamic field and groundwater chemical field.On the basis of this,this paper expounds the groundwater pollution problems caused by mine closures.According to different buried depth of groundwa...
