Pumping test in the fracture-karst aquifer in Zhangji well field in Xuzhou

Based on the assignments in the phase of detailed reconnaissance in Zhangji well field in Xuzhou,as well as its characteristics of hydrogeology,the new technical requests and working methods for the pumping test in Zhangji well field is proposed.The results of the tests show that the new technical requests and working methods not only satisfy with the request of numerical calculation for the evaluation of groundwater,but also fit for the situation of electrical webs and wells,in addition saves the outlays.In the meantime,the conclusions are important value for the evaluation and ministration of groundwater resources in the large-type well fields.
