Abstract

Abstract

The deficiency of water resources has seriously affected the economic and social development of southern Jiangxi. In this paper, ground water has been successfully found through the hydrogeological survey combined with the direct current prospecting in the granite and the Cambrian metamorphic rock distribution areas in Ganxian District, Ganzhou City, which has contributed to the poverty alleviation in the district and laid a solid foundation for the rural revitalization strategy. The specific working methods are as follows: (1) In the granite area, firstly the shallow strongly weathered structural fissures were determined as potential target water-bearing beds through hydrogeological survey, and then were verified the distribution, thickness, scale and water-bearing characteristics by the direct current prospecting. (2) In the Cambrian metamorphic rock area, the target layer for water exploration is the structural fractured zone, the distribution and trend of which were firstly determined through hydrogeological surveys, and then the development characteristics and water richness of which were explored bydirect current prospecting. The results show that the water-rich area was successfully detected by the above methods, which provided data for the comparison and precise positioning of boreholes. The following drilling and pumping tests verified the interpretation results of geophysical exploration, and water output of both boreholes achieved the expected goals. The groundwater search can provide reference for local groundwater exploring work.
