Abstract: In the process of low-carbon development, carbon dioxide emission reduction in mining cities is one of the problems that must be faced.This paper classifies 75 mining cities from the perspective of life cycle and resource type, and compares the differences by using city energy consumption data, population data and economic data(GDP).After that, this paper explores the correlation between carbon dioxide emissions and economic development in different mining cities.The results show that the cities with high and low carbon dioxide emissions are spatially concentrated.Carbon dioxide emissions in mature coal-based cities are generally higher than mature non-ferrous/non-metallic metals cities and there is a big gap between them.In different mining cities, the proportion of carbon dioxide emissions in different energy types has both similarities and dissimilarities, and showing varying degrees of positive correlation between carbondioxide emissions and economic development.To achieve low-carbon development in mining cities, the state should pay close attention to high-carbon mining cities, stabilize low-carbon mining cities, speed up the economic transformation and improve the efficiency of mining, production and utilization of mineral resources.
