Abstract: Under the tight constraints of resources and environment and the downward pressure of economy, the contradiction between the development and utilization of mineral resources and economic development, social progress and public demand has become increasingly prominent.In order to solve the problems of insufficient investment in the ecological restoration of abandoned mines, a government led and social multi subject participation investment and financing mode should be established.Based on the analysis of the cost expenditure and income process in different stages of ecological restoration of abandoned mines, the advantages and precautions of traditional financing tools that are loan financing and equity financing are summarized.The characteristics, relevance and sources of funds of diversified financing tools used for ecological restoration projects of abandoned mines were described.The limitations of financing and coordination problems on the investment in ecological restoration of abandoned mines are expounded.It is proposed to increase investment in the ecological restoration of abandoned mines, through playing a decisive role of the government, attracting social capital investment, playing the role of social organizations, and encouraging local people to participate.
