Abstract:The protection measures of mine ecological environment should follow the order of "avoiding, slowing down and compensation", strictly controlling the damage caused by the development and construction of mine, and carrying out the principle of "who pollution, who prevent and control, who develop and protect", strengthen the ecological protection and construction, and coordinate the economic and economic benefits. Therefore, in the process of mining development, ecological restoration should be carried out in time, green mine construction should be promoted actively, and the development of mineral resources and ecological environment protection should be coordinated to develop. Taking the Donganshan Iron Mine in Liaoning Province as an example, this paper analyzes the impact of mining on the ecological environment of non-ferrous metal mine, summarizes a series of ecological restoration measures, summarizes the advanced ecological management experience, and puts forward corrective measures and suggestions for the existing ecological environment problems in the mine.
