艾娜克铜矿水源地地下水允许开采量计算及影响评价
|
摘要
为保护阿富汗艾娜克铜矿一带地下水资源环境,同时在开采期间不发生危害性的环境水文地质问题,根据在阿富汗艾娜克铜矿一带进行的供水水文地质勘查成果及水源地稳定流抽水试验成果采用补偿疏干法对水源地的允许开采量进行计算并对水源地取水后对当地地质环境的影响程度进行评价,本水源地为山间河谷调节型水源地,本次研究确定的地下水资源储量1 255~28 m3/d,精度为探明的(B级)允许开采量。水源地开采运行后不会对周边产生危害性沉降,但是会对影响半径范围内的(北段1 240 m、南段1 860 m)居民生活生产用水造成不同程度的影响,需要采取相应的措施确保铜矿水源地正常开采运行。
For the protection of groundwater resources environment in the area of Afghanistan Aynak Copper,and the prevention of harmful environmental hydrogeological problems in the mining period,according to water supply for hydrogeological,exploration results in the area of Aynak copper mine and steady flow pumping test results,the allowable production volume of water sources can be calculated and influence on the local geological environment can be assessed with compensation dewatering method. The water source regulated by intermountain and valley has been identified that the reservation of groundwater resources is 1 255 280 m3/d. The degree of accuracy for allowable exploitation is B. Which will not generate hazardous settlement to the surrounding after operation,however it may cause varying degrees of influence to the residents' water supply within radius of influence( northern section of 1 240 m,the southern section 1 860 m). It is necessary to take corresponding measures to ensure normal production of water resources.
