Analysis of the Dynamic Change of the Environmental Carrying Capacity and Influencing Factors of Mature Coal Cities

Abstract

Coal is the main energy source in China. In 2010-2020, raw coal accounts for more than 70% and 56% of its production and consumption of primary energy resources respectively, and the status that taking coal as the main energy source will not change for a long time. According to the guarantee term of coal resources and the accumulation degree of resistance in development, coal cities in China can be divided into four types: growing coal city, mature coal city, declining coal city and regenerating coal city [1]. Growing coal cities take 22% of all prefecture-level coal cities. Their coal resources reserves are large but the mining modes may not be standardized. The economic development
