Research on a Carbon Emission Calculation Model and Method for an Underground Fully Mechanized Mining Process

Abstract

With the ratification of the Paris Agreement at the Paris Climate Conference, reducing carbon emissions has become a global interest. Coal is one of the main industries causing carbon emissions; thus, quantifying carbon emissions from coal mining is an important step in reducing these emissions. Firstly, based on the life cycle idea, in this paper, we define the Carbon Emission Boundary of the fully mechanized coal mining method. Secondly, the carbon emission accounting model (B-R model) of fully mechanized coal mining is established, which includes the total amount of carbon emissions and the carbon emissions of each mining link during the mining process. The Fifth-II mining area of the Jinda Coal Mine in Tengzhou City is taken as an example. We collect the relevant data on carbon emissions in the mining process of the Jinda Coal Mine, and the B-R model is used to obtain the carbon emissions in the mining process of this mining area. Finally, the feasibility of the B-R model is further verified according to the international authoritative carbon emission IPCC calculation method and the China Coal Production Enterprises Greenhouse Gas Emissions Accounting Methodology and Reporting Guide. The results show that the B-R model in this paper is feasible and that the greatest amount of carbon emissions arises from the coal breaking link and coal transportation, which provides a basis for other coal mines to calculate carbon emissions. The B-R model lays a foundation for coal mines to formulate a carbon emission reduction system.

Simulation of carbon emission for mining‐separating‐backfilling integrated coal mines based on system dynamics

“…SD believes that the behavior pattern and characteristics of a system mainly depend on its internal dynamic structure and feedback mechanism 25 . Most of the existing research on coal mine carbon emissions are to establish energy consumption and carbon emissions lists through the life cycle or calculate energy consumption and carbon emissions of various production links through accounting models 16–20 . These methods need a lot of data support, but the relevant data of coal mines are relatively scarce and difficult to obtain.…”

In addition, these methods cannot reflect the causal relationship of the internal factors in the system.…”

“…Wang et al 16 analyzed the carbon emission system and emission reduction path of coal mining areas, established the carbon emission accounting model, and clarified the low‐carbon and green development direction of coal mining areas. Meanwhile, the life cycle is widely used to define the carbon emission boundary in the process of coal mining, based on which the carbon emission accounting model in the process of coal development is established, and it was found that direct methane emission is the main source of carbon emissions from coal mining 17–19 . In addition, Liu et al 20 compared the energy consumption and carbon emissions of truck and belt conveyor transportation systems in open‐cut coal mines.…”

[17][18][19] In addition, Liu et al 20 compared the energy consumption and carbon emissions of truck and belt conveyor transportation systems in open-cut coal mines. Chen et al 21 estimated the methane emissions from abandoned coal mines in China from 1980 to 2020, and predicted the methane emissions from abandoned coal mines in China in the next 40 years.…”

The increasing atmospheric CO2 over India: Comparison to global trends

“…The seasonal trends are largest in winter and autumn, at about 2.3 ppm/yr. The highest trends coincide with the energy consumption, mining, and refinery regions in western and eastern India Li et al (2022). described that coal is one of the main industries causing carbon emissions.…”
