摘要
灵寿县丘陵区是太行山前典型的缺水地区,通过水文地质调查、物探、钻探等综合勘探手段,成功施工了探采结合井,并通过抽水试验评估了可开采量。通过本次地下水勘查,表明在太行山前变质岩分布区找寻岩溶裂隙水,需要充分分析地质条件找寻可溶蚀性岩层,结合地形地貌重点勘查具有较大汇水面积地段,同时考虑岩性变化界线形成的储水空间。此外,采用水文地质详查结合先进的物探钻探工艺是一种有效的地下水勘查技术方法。灵寿丘陵区的地下水勘查具有很强的实践意义,为此类变质岩分布区地下水找寻起到了示范作用。
The hilly area in Lingshou County is a typical water shortage area in the Taihang piedmont. The exploitation wells were successfully constructed in this area according to the methods of hydrogeological survey, geophysical survey, and drilling, and then the allowable groundwater withdrawal was determined using the pumping tests. In order to find the karst-fractured groundwater in the metamorphic rock area of the Taihang piedmont, the geological conditions are needed to be analyzed to determine the water-erodible rock layers,the topographic conditions are evaluated to explore the large catchment area,and the water storage spaces formed by the changes of lithological conditions are also considered. In addition, the hydrogeological investigations combined with the advanced geophysical and drilling processes are e{fective groundwater exploration techniques. Groundwater exploration in the hilly area of Lingshou County has a strong practical significance ,for finding groundwater in the metamorphic rock area.
