摘要
木头峪水源地的建成、运行能够有效缓解陕北佳县的水资源供需矛盾。研究区内第四系厚度多在10~15 m之间,所以,可以考虑采用管井开采方式开采区内地下水。为了减少水源地的建设运行成本,保证出水量比较大,在统计、分析了研究区水文地质条件的基础上,建立了研究区地下水流数值模型。根据单井开采量的不同和开采井间距的不同,共设计出了9种可行的管井开采方案,并对比、分析了各可行方案的模拟结果。综合考虑了出水量、降深等因素,确定的优选方案为：开采井间距100 m,单井开采量700 m^3/d,总开采量10 500 m^3/d。
Wood valley water sources built, running can effectively alleviate the supply and demand of water resources in northem Shaanxi JIAXIAN. Quaternary research area more in thickness between 10 - 15 m, so consider using tubewell groundwater mining methods mining district. In order to reduce the cost of construction and operation of water sources, to ensure that the water is relatively large, the statistical analysis of the basic research area on hydrogeological conditions, the establishment of a numerical model of groundwater flow. Depending on the different single well spacing and mining extraction wells, a total of nine kinds of design viable mining plan tube wells and contrast, analysis of the simulation results of the feasible options. Considering the amount of water, drawdown and other factors identified in the preferred embodiment as follows： extraction wells spaced 100 m, single-well extraction 700 m^3 / d, the total extraction volume 10 500 m^3 / d.
