Research on low-carbon operation mode of coal mine based on life cycle

Abstract

Based on the theoretical framework of the whole life cycle theory and the specific production process of underground mines, this research focuses on a comprehensive analysis of the carbon emission accounting boundaries and sources within the entire life cycle of underground mining. Furthermore, a robust carbon emission accounting model is developed specifically for the entire life cycle of coal production. Subsequently, a case study involving an actual coal mine production scenario is conducted, wherein the model is utilized for analysis and calculation purposes. The comprehensive analysis and calculation results reveal that electricity usage constitutes the primary source of carbon emissions within coal mines, closely followed by methane escape and greenhouse gas emissions resulting from fossil fuel combustion. Based on these findings, the research then proposes strategies for low-carbon operations and the implementation of carbon reduction technologies in coal mines. By conducting a detailed analysis of the carbon emission accounting within the whole life cycle of underground mining and providing concrete findings and practical recommendations, this paper contributes to the understanding and management of carbon emissions in the coal production sector.
