Abstract: Abstract In order to study the carbon emission of coal resources from mining to utilization and its influencing factors, the Life Cycle Assessment method was used to calculate the carbon emission of coal mining, transportation and consumption from 2001 to 2018, Then, Logarithmic Mean Divisia Index method is used to decompose the factors that affect the carbon emissions in each stage: (1) Mining stage: energy structure, energy intensity, per capita output, personnel scale; (2) Transportation stage: Diesel utilization efficiency, coal cargo turnover; (3) Consumption stage: economic scale, industrial structure, coal consumption intensity, respectively calculate the contribution value and contribution rate of each factor to carbon emission growth. The results show that the carbon emission in the whole life cycle of coal mainly comes from the stage of mining and consumption; Energy intensity, diesel utilization efficiency and coal consumption intensity have inhibitory effects on carbon emissions, and personnel scale and industrial structure have changed from promoting factors to restraining factors; Per capita output, coal cargo turnover and economic scale have a sustained role in promoting carbon emissions; The energy structure effect is unstable. Through in-depth analysis of the above carbon emission influencing factors, relevant conclusions and suggestions are put forward.
