煤矿开采条件下地下水资源破坏及其控制

煤矿开采使地下水资源遭到严重破坏，其主要原因表现在两个方面：煤矿开采对含水层结构的破坏及煤矿开采对地下水环境的影响。本文在扼要分析这两方面原因基础上，提出了煤矿开采条件下控制地下水资源破坏的有效措施，这些措施包括：防止或减轻含水层结构的破坏，维护地下水环境平衡及矿井水综合利用。结论认为：煤矿开采对地下水资源产生破坏不可避免，但采取一定措施，可以大大减轻其受破坏的程度；在控制地下水资源破坏时，应考虑经济、社会和环境三方面的效益；对地下水环境演化进行深入研究，充分利用矿井水是控制地下水资源破坏的理论和技术措施。

The Destruction of Groundwater Resources and its Control Under the Circumstances of Coal Mining

Coal mining makes the groundwater resources destroyed seriously. The main reasons are the following two aspects: firstly the destruction to aquifer structure, and secondly the impact to groundwater environment. on the base of briefly analyzing above two aspects reasons,available measures of controlling the destruction of groundwater resources under the coal mining circumstances is given in the paper, and these measures include avoiding and lightening the destruction to aquifer structure, preserving the balance of groundwater environment,and comprehensive utilization of mine water. The conclusion is given as the following: the destruction to groundwater resource under coal mining is not avoidable, but the destruction degree can be lightened by taking some preventing measures; When the measures of controlling the destruction of groundwater resources are taken,efflciency of economy, society and environment must be considered; Carring out a thoroughgoing research on groundwater environment evolution and making full use of mine water are the theoretical and technical measures in controlling the ground water destruction
