Due to the strong disturbance of geological environment in mine resource development, especially the mining geological environment caused by open pit mining is particularly serious. It is urgent to implement comprehensive improvement of mine geological environment and repair the ecological environment of mining area. In this paper, the mine environmental impact assessment was divided, the mine geological environment was more serious (B) and the less affected area (C) was evaluated. The results showed that the scheme would be divided into areas with more serious geological environment (B) and areas with less geological environment (C). Since the mining activities were concentrated in the area with serious impact on the geological environment (B), the suitability of the mine site was basically suitable. Geological environmental protection and restoration were carried out by means of  mining while protecting the environment.
