Abstract: The groundwater depression cone is an inevitable physical phenomenon in the groundwater exploitation of pumping well, which can cause different environmental problems or geological disasters at different development stages combined with different engineering geology and hydrogeology conditions. The groundwater depression cone is classified in terms of formation time, well number, damage degree and development trend based on the analysis of occurrence, development and possibility of geohazards, aiming to help the understanding of the nature of groundwater depression cone and implement scientific management of groundwater resources.
