地下水可采资源量计算及若干问题探讨

对山西省汾河中上游地区平原区、山区地下水可采资源量进行了计算与分析。对平原区可采资源量采用保证率下的直接估算法、可采系数法、平均布井法、径流模数法、水量均衡法等多种方法进行计算,再以优化法进行组合;对于山区,重点讨论了岩溶水可采资源量的计算方法,最后得到较合理的结果。在平原区、山区可采资源量计算中,对各种计算方法存在的问题及解决思路进行了详细的阐述。

Discussion on some problems on calculation of volume of groundwater available for mining

The volume of groundwater available for mining in plain areas and mountainous areas on the upper and middle Fenghe River of Shanxi Province is calculated and analyzed. For plain areas, some methods, such as the direct evaluation method under a guarantee ratio, the mining coefficient method, the method of uniform distribution of wells, the runoff modulus method, and the water volume equilibrium method, are adopted for calculation of the volume of groundwater available for mining, and satisfactory results are obtained by optimal combination of the above methods. For mountainous areas, the emphasis is placed on the calculation of the volume of karst water available for mining, and some reasonable results are drawn. Furthermore, some problems in various methods and ways of their solutions are discussed in detail.
