Abstract The mining technology of fully mechanized coal mining face consumes a lot of energy while obtaining coal resources, and these energy consumption is also accompanied by carbon dioxide emissions. In order to evaluate the impact of coal mine underground mining process on the environment from the perspective of carbon emissions, v Based on the life cycle assessment method, this paper takes the fully mechanized mining face as the main research object, studies the carbon emissions and energy consumption of each process link in the underground mining process of coal mine, and establishes the carbon emissions calculation model of the fully mechanized mining face. Taking the A303 working face of a mine in Xinjiang as the engineering background, the carbon emissions in the mining process of the working face are calculated and analyzed, and suggestions for improvement are put forward for the links with high carbon emissions and energy consumption. The research results can promote energy conservation and emission reduction in coal mines, which is of great significance to the low-carbon production of coal mines under the background of ' carbon peak, carbon neutralization '.
