Although the closed pit mine is no longer mined, the pre-mining behavior still causes some damage to the environment. In this paper, the present situation and prediction of environmental geological problems in closed pit mine were evaluated from the aspects of mine geological disaster, mine aquifer destruction, mine topography and landscape destruction, mine soil and water environment pollution, etc. The results showed that the geological environment was complex and the evaluation level was grade one. Finally, it was suggested that the geological environment of mine should be restored and the corresponding measures should be adopted for the division of different grades. The research results of this paper were intended to provide reference for the analysis of environmental geological problems in other related mine closed pits.
