煤矿资源开采对含水层的影响

Analysis of Influence of Coal Mining on Aquifer

煤矿开采使围岩变形和移动,岩层移动影响到含水层结构受到破坏,引起地下水补径排关系的改变,对地下水资源的形成与赋存规律产生影响。从煤矿开采方法对含水层结构的影响、顶板岩层结构特征的改变对含水层结构的影响、煤矿区构造含水层结构的影响等进行分析,并通过具体实例分析阐述煤矿资源开采对含水层的影响。近年来,煤矿开采对地下水造成严重影响,给人民生产生活造成影响,因此研究煤矿开采对含水层的影响意义重大。

Coal mining , which results in the deformation and displacement of wall rock , the dis-placement of rock stratum will have an effect on the structure of aquifer and even destroy it.Mean-while , the displacement of rock will change the relationship between the supply and runoff of ground -water , and affect the formation and occurrence regularity of groundwater resources.This paper analy-zes the impact of the method of coal mining on the structure of aquifer , the change of the roof rock structure feature on the structure of aquifer and aquifer structure of coal mining area.And it also states the impact of coal mining on aquifer via analyzing a specific example.Coal mining had a seri-ous influence on groundwater and the people′s production and living in recent years , so it is of great significance to study the influence of coal mining on aquifer.
