Ecological Restoration And Reconstruction In Open Pit Mining

China is the world-famous resource country with rich reserves of mineral resources.With the continuous improvement of social productivity,the mining of mineral resources is becoming more and more frequent,which leads to a series of irreversible environmental problems.Because of the rapid development of alumina products,the exploitation of bauxite is also increasingly intense.Different from coal mine,bauxite is generally small mine with small mining area and shallow mining depth.The difficulty of ecological recovery is relatively small and investment is small,and it is easy to get obvious effect in the short term.This paper takes Pinglu bauxite as a case,the mining area of natural and social environment and mining method and technical conditions for fully understanding,through the ecological succession model of mines found high levels of sustainable development mode.Through the field investigation,the "3S" technology is used to investigate the distribution of natural resources in our province and the current status of the damage to the terrestrial ecosystem in the non coal mine mining.After investigating the ecological restoration status of the mining area,the ecological restoration scheme suitable for the mine is formulated with the guidance of the ecological theory.By predicting the ecological restoration results after the implementation of the ecological restoration scheme,the vegetation coverage rate of the bauxite mining area increased,the biodiversity increased,the soil and water conservation increased,and the overall situation of the land use situation was dominated by bare land,shrub land and grass,and the net productivity was increased.The effect of ecological restoration is obvious.This paper provides some technical reference for the ecological restoration and reconstruction of open pit mining in the future,and contributes to the construction of "green mine"...
