Abstract:Through studying present condition of abandoned open pit mines in Shandong province, existing geological environment problems in mines have been analyzed. On the basis of summarizing ecological restoration of abandoned mines in the past, guiding by "Carbon Peaking and Carbon Neutrality Goals", the objects, technologies and restoration directions involved in ecological restoration of abandoned open-pit mines have been systematically studied, and five ecological restoration modes of abandoned open-pit mines have been summarized, including ecological greening, agricultural land, science popularization and education base, tourism land and construction land. Taking ecological restoration experiences of abandoned open-pit mines in Shandong province as an example, practical application of five mine ecological restoration modes in ecological restoration of abandoned open-pit mines left over from history has been introduced.
