Geological disasters caused by mine geological and ecological environment problems have always been the bottleneck restricting the development of some areas. In order to repair the geological landform and reduce soil erosion, effectively eliminate geological safety hazards of abandoned mines and improve the green plant coverage of abandoned mines, an abandoned open-pit mine in Yangxin County, Hubei Province was taken as a reference case. This article analyzes the ecological and geological environment issues of the abandoned mine. Using the technology of ecological protection and restoration, the high and steep slope of the mine was treated by the comprehensive treatment strategy of ' slope clearing + retaining wall + drainage ditch + edge sealing wall + site leveling + guest soil spray seeding greening + soil covering greening '. The geological environment and ecological environment were restored, and the artificial greening landscape coordinated with the surrounding natural environment was formed, which achieved the purpose of ecological restoration and management. This research and engineering practice not only achieved the goals of ecological environment protection and vegetation restoration, but also explored a new path in the field of mining ecological environment restoration and governance, providing valuable experience for similar mining vegetation restoration.
