潼关县是重要的黄金采、选、冶、加工工业区之一,地处秦岭、黄河及渭河阶地地带,以往该地区地下水资源勘查评价不系统,且具有局部性,该地区矿产资源的开发导致可再生的地下水资源未得到合理的开发利用,局部地区的不合理开采引发了地下水位下降、水环境污染、生态环境恶化等问题。在系统分析整理前人研究成果的基础上,对研究区采用水文地质及开采现状调查、地面物探、抽水试验及水质化验等手段,获得比较系统、科学、全面技术资料,计算相关水文地质参数、水资源量及开采潜力等。经计算,研究区地下水天然资源补给量127774.45m3/d,储存量4434806024.0m3,天然可开采资源量为87414.80m3/d,剩余开采资源量33464.12m3/d。经评价该区地下水可开采量及开发潜力为中等地区,并提出开发利用建议。

Tongguan county is one of the important industrial zones of gold mining, processing, smelting and processing,which is located in the Qinling Mountains, Yellow River and Weihe River terraces. In the past, the exploration and evaluation of groundwater resources in this area is not systematic and localized. The exploitation of mineral resources in the arealeads to the unreasonable exploitation of renewable groundwater resources, and the unreasonable exploitation in some areasleads to problems such as the decline of groundwater level, pollution of water environment and deterioration of ecological environment. On the basis of systematic analysis of previous research results, using hydrogeological and mining status investigation, surface geophysical, pumping test and water quality test, we obtain comprehensive scientific and technical data, and calculate relevant hydrogeological parameters, water resources and exploitation potential. The study area’ s groundwater naturalrecharge is 127 774. 45 m3 / d, storage is 4 434 806 024. 0 m3, natural recoverable resources are 87 414. 80 m3 / d, and theremaining exploitation resources are 33 464. 12 m3 / d. The groundwater recoverable amount and exploitation potential in theresearch area is medium level, and suggestions for development and utilization are put forward.
