Study on Ecological Restoration Technology of Mine Wasteland

Abstract

Mining destroys the environment and occupies arable land, causing serious social problems. In recent decades, land reclamation and ecological restoration of mine wasteland have become a hot topic of interdisciplinary research. However, compared with developed countries in Europe and America, China's mine wasteland work has the characteristics of low land reclamation rate and poor reclamation quality. This paper discusses the soil reconstruction technology, physical and chemical improvement technology and vegetation restoration technology of land reclamation. At the same time, it is believed that the research on the ecological environment impact mechanism of mine wasteland should be strengthened. In the later stage, modern advanced technologies, such as 3S technology and information system technology, should be used to assess and supervise the reclamation work, and strive to achieve the technical breakthrough in the environmental damage mitigation of mine wasteland, and establish the theoretical system and technical specifications for the reclamation and ecological restoration of mine wasteland.
