淮南市朱集东矿井新生界松散层地下水开采保证程度评价

利用淮南市朱集东矿井新生界松散层供水水文地质勘探成果和抽水试验资料,查明了区内新生界松散层供水含水层的供水水文地质条件,认为第一含水层埋藏浅,易受污染,水量随季节变化大,不宜作为生活饮用水供水水源,第三含水层水质较差,亦不作为生活饮用水供水水源,确定了第二含水层为矿区主要供水层位。采用解析法对第二含水层的水量进行了计算,并设计了布井方案,计算了井群水量;水位预报结果表明,开采50a后,3#、4#井中的水位最大降深为35.229m,小于其顶板埋深,说明拟建井群布置是合适的。评价结果为矿井供水设计提供了依据。

Cenozoic Loose Beds Groundwater Exploitation Assurance Level Assessment in Zhuji East Coalmine,Huainan City

Using Cenozoic loose beds water supply hydrogeological exploration results and pumping test data in the Zhuji East coalmine,Huainan City,have identified water supply hydrogeological condition of aquifers,considered that the first aquifer is shallowly buried,easy to be polluted and water quantity variable along with seasons,not suitable for drinking water supply;the third aquifer has poorer water quality,thus the second aquifer has ascertained as the mine area main water supply aquifer.Water yield of the sec...
