Abstract: As a typical mining city，Tongling relies on the exploitation of mineral resources. Over the years，mining activities have been accompanied by various types of mine geological environment problems. In order to determine the impact status of the mine geological environment in Tongling and delimit the zoning of the impact degree，the article determines the types，distribution characteristics and causes of the mine geological environment problems by sorting out the“mine geological environment survey report”and“mine geological environment protection and land reclamation plan”in Tongling.The evaluation index was determined according to the selection principle of the index，the index was standardized by quantitative and qualitative methods according to the index attributes，and the evaluation index system was constructed. Finally， the AHP hierarchical analysis and fuzzy mathematics comprehensive evaluation were used to classify the geological environment impact of mines in Tongling City into three levels: serious area，serious area and general area. The results show that there are 8 serious (Ⅰ)，6 serious (Ⅱ) and 4 general (Ⅲ) areas affected by mine geological environment. The areas with serious impact degree of mine geological environment are mainly centered around the main mining conce，ntration area and the surrounding area of the mining area. The zoning results are basically consistent with the actual situation of mine geological environment，which can be used as the basis for the local government to delimit the zoning of mine geological environment protection and treatment.
