Abstract：The continuous deficit of deep groundwater caused by long-term exploitation in North China has caused a series of serious ecological and geological environmental problems such as land subsidence,which poses a great threat to the water security and sustainable development in North China,especially in Beijing,Tianjin and Hebei.It is of great significance to carry out deep confined groundwater treatment and restoration.Analyzes the present situation and problems of overexploitation in North China,then combs the practical cases of artificial recharge for deep groundwater at home and abroad.Finally,according to the working idea of the combination of"point,line and surface"and the systematic treatment and repair mode of"pressure mining,surface recharge and artificial recharge",the measures and countermeasures are put forward to provide reference for the next step of deep confined groundwater treatment and restoration.
