Research On Geological Environment Assessment And Ecological Restoration And Control Of Shaanxi Silver Mines

Mineral resources are an important foundation for social development and economic progress.The development of mineral resources inevitably disturbs the geological environment of the mine and destroys the local ecological environment.Especially the geological environmental problems and ecological environment problems caused by the development of metal mines are more serious..With the development of social civilization,people's demands for life gradually change to improve the quality of life and improve the ecological environment.As a part of normal life production,mines have gradually become the focus of the people and the society..Ecological environmental protection is an important basic work in the construction of ecological civilization,and ecological protection and restoration is a key point repeatedly emphasized in China at this stage.The report of the 19 th National Congress of the Communist Party of China pointed out that building an ecological civilization is a millennium plan for the sustainable development of the Chinese nation.Therefore,vigorously rectifying the geological environment of the mining area to improve the ecological environment of the mining area and improve the mining area and surrounding ecological environment has become the focus of research at this stage.As a resource-exhausted large-scale state-owned mine,Shaanxi Silver Mine has been listed as a key mine in the National Mine Geology Environmental Protection and Treatment Plan.After decades of mining,it has changed the original topography and landscape,and occupied the forest land,causing great soil and water pollution.At the same time,there are also many hidden dangers of geological disasters.The geological environment and environmental problems in the mining area are very prominent,and the ecological environment is seriously damaged.In the process of restoration and management,Shaanxi Silver Mine is to eliminate the hidden dangers of geological disasters in the mining area,improve the geological environment of the mining area,restore the ecological environment,and finally coordinate with the surrounding environment.This paper briefly describes the current research status of mine geological environment at home and abroad and some policy requirements.The local natural geography environment and the geological conditions of the mining area in Shaanxi silver mine were reviewed.The engineering geological conditions of the mining area were obtained through site investigation.The main geological environmental problems and characteristics of the mining area were studied and analyzed.The main geological environmental problems in the silver mines in Shaanxi included geological conditions.Disaster problems,aquifer damage,topographical landscape damage,land resource destruction and water and soil pollution are destroyed.The gray correlation degree method was used to evaluate the geological environment of Shaanxi silver mine,the evaluation factor was selected,and the evaluation system was established.The research area of the valley was divided into 29 units,and the Shaanxi silver was finally obtained through evaluation.The serious impact area of the mine geological environment occupies 17 units,and the more severe areas occupy 7 units,and the lighter areas affect 5 units.In view of the specific problems existing in the geological environment and the more serious areas,the project management plan and the ecological environment restoration plan were proposed,and the geological environment management and ecological environment restoration of the silver mine in Shaanxi were finally completed.It provides reference for the geological environment assessment and ecological restoration of the same type of mine in the future.
