摘要
Longdong Basin underlying complex aquifer is a large-scale sedimentary basin with arid climate and closefisted mean annual precipitation in Southwest of Ordos basin and eastern area of Gansu Province,where abundant mineral resource is present and one of the important components of national energy base.Water resources shortage is restricting economic development.A thick underground fresh water is exploration proved in recent years,this will effectively alleviate to shortage of water resources.How to rationalize the exploitation of deep groundwater resources become a problem to be solved.Update capabilities,aquifer pore characteristics,exploitation amount and availability of the cretaceous deep groundwater are analyzed based on the hydrologic geological characteristics of confined water in Longdong basin.Development and utilization of deep groundwater are discussed by Solving Parameters and Analytical method of trial etc in typical groundwater field.Pointed out that resources exploitation of Cretaceous deep groundwate to consume elastic storage capacity,but it is a modest development and utilization because of rich reserves,good mining conditions.Moreover,put forward Distributed deployment middle-sized,small groundwater field,by stages,the regional exploitation scheme.Finally,paper give some advice for Mining well drilling technology and Protection measures of deep groundwater.And expecting reference value for rational exploitation of the deep groundwater in Longdong Basin.
