摘要
我国煤炭资源丰富,煤炭开采对地下水资源造成破坏。把调查区分为井田内开采区、井田内未开采区及井田外地区3个区域,在对襄垣县41座煤矿井田及其周围86个村庄的86口水井的地下水资源进行调查的基础上,运用SPSS对其进行简单相关性分析和独立样本T检验分析得出:煤炭开采是造成地下水资源破坏的重要原因之一,对不同地区的地下水资源具有不同程度的影响。即井田内开采区地下水水位平均下降了76.9 m,井田内未开采区地下水水位平均下降了20.1m,井田外地区地下水水位平均下降了6.3 m。此研究对区域的煤炭开采及地下水资源的保护具有重要的现实意义。
The process of coal mining caused great damage to groundwater resources,eventually leading to serious water shortage in mines and surrounding areas.This paper conducts an investigation and analysis of groundwater resources in 41 coal mines and surrounding 86 wells in 86 villages at Xiangyuan County,and applying SPSS,the analysis of independent samples test on data shows groundwater level changes caused by coal mining in different areas,that is,at exploited mining groundwater level falling by an average of 76.9m within the mining areas,at un-exploited mining groundwater level declining by an average of 20.1m within the mining areas,groundwater level outside the mining region falling by an average of 6.25m.The study has important practical significance on the region's coal mining and the protection of groundwater resources.
