Abstract
A certain construction stone mine(tuff)is located in Pingchuan district,Baiyin city,it is a policy closed mine and is currently abandoned.The mining method of this mine is open-pit mining,and historical mining activities have formed one mining pit,one topsoil stripping area,one mining road,four slag piles,and one office and living area,however,ecological restoration and management have never been carried out,causing a series of geological and environmental problems in the mine.Among them,mining excavation causes a large area of exposed bedrock,greatly increasing the number of free surfaces,and forming unstable slopes;mining activities alter the original terrain conditions and features,resulting in the destruction of the natural landscape of mines in terms of aesthetics,continuity,integrity,and originality;mining causes damage to mountains and occupation of slag piles,resulting in damage to land resources.Regarding the existing geological environment issues,a restoration and control plan is proposed to restore the geological environment of the mining area.关键词
