摘要：
A comprehensive research approach using surface hydrogeology survey, hydrogeological drilling and groundwater resources development and utilization, found that the groundwater types in the study area are mainly bedrock fissure pore water, carbonate karst water, and Quaternary loose rock pore water as auxiliary, and the occurrence characteristics of different types of groundwater are summarized. The influence of geological structure on groundwater migration, storage, enrichment and discharge in the study area is clarified from the characteristics of fracture, fold and fracture development. Fracture crushing zone usually has water-blocking effect, while in the influence zone of one or both sides of the fault is often filled with water, and the groundwater discharge zone is easily formed along the development direction of fault zone. Secondary fault is the main structure controlling the deep hot water active channel in the research area. Syncline structure makes shallow fissure water and lower layer water enriched, forming syncline water storage basin. The near East-West tensile and X joint fissures are beneficial for the enrichment of groundwater. According to the main topography and aquifer characteristics, the study area is divided into three main types: intermountain basin, hilly area and karst area. Through the analysis and summary of groundwater occurrence characteristics and laws in each type of area, combined with the feasibility of development and utilization, three groundwater development and utilization modes are summarized: the drilling and pumping model of water storage structure in the intermountain basin, the regulation and storage model of surface spring pool in the hilly area, and the surface underground joint model of the reservoir formation of the depression and the underground river plugging hole in the karst mountainous area. The research results provide a scientific basis for improving the efficiency of groundwater development and utilization in the Wumeng Mountain area and solving the problem of water use in this area. © 2021, Science Press.
