Research Progress on Key Technologies of Ecological Restoration in Metal Mines
The exploitation and utilization of mineral resources has made an important contribution to the development of the national economy.In the early metal mine development,there were problems in cognition,technology and policy,which resulted in the destruction of the surface ecosystem and the change of the original ecological environment in the mining area.In order to restore the ecological environment of metal mines,this paper took Guangdong Province as an example to focus on the distribution of metal mines,the types of ecological damage of mines,and the mode of ecological restoration of mines,combining the multi-dimensional ecological environment,mine management,ecological restoration and biological restoration.Starting from the existing mature technologies,and combining with the local characteristics of the mining area,the ecological restoration of the mine was realized,and the ecological concept of"clear waters and green mountains are as good as mountains of gold and silver"was thoroughly implemented.
