煤矿开采环境影响评价中地下水问题探析

Exploration and Analysis on Groundwater Issue for Evaluation of Environmental Influence in the Course of Exploitation of Coal Mine

煤矿的开采与地下水资源紧密相连,煤层往往与地下含水层相邻,采煤时会疏干地下水,这不仅影响了地下水资源的数量和质量,而且破坏了水的动态平衡和生态环境,造成一系列不良后果。根据煤炭开采工程的环境影响特点及环境保护的最新发展趋势,概略提出了煤矿区地下水环境影响评价的相关问题、煤矿开采引起的地下水环境问题、以及由煤矿地下水疏干引发的地面沉陷及其植被景观的影响。

There is a close relation between exploitation of coal mine and groundwater resources. The layer of coal is usually border upon the aquifer of groundwater, which not only influence the quantity and quality of groundwater resources, but also destroy dynamic balance and eco - environment of water and result in a series of ill result. According to characteristics of environment influence and the newest development trend of environment protection in the course of coal exploited engineering, the article briefly puts forward some relative issues about evaluation of environmental influence of groundwater, about groundwater environment owing to coal exploitation as well as some issues about floor sinking and influence in vegetation sight owing to dredging up groundwater in the coal area.
