Research on the implementation path of carbon emission reduction in coal mine under the carbon peak and carbon neutrality strategies
With the promotion of the carbon peak and carbon neutrality strategy,coal production enterprises have proposed construction goals such as"zero carbon emission mines",focusing on reducing carbon emissions in the coal mining process.Based on the analysis of the sources and structural composition of carbon emissions from coal mines,a combination technology implementation path of carbon emission reduction,zero carbon emission,and negative carbon emission is proposed.Taking a newly construction mine with a coal production capacity of 20 million ton per year in the western China as an example,the carbon emissions,implementation path and the contribution of carbon emission reduction are quantitatively analyzed.The results indicate that the contribution of low-carbon transformation of coal mine energy systems and carbon sequestration reduction in mining areas is limited.It is necessary to develop green electricity with wind,solar and other new energy,optimize mining processes to reduce CH4 and CO2 escape emissions,carry out CO2 mineralization and other technologies to achieve significant carbon emission reduction,and ultimately achieve mining production with zero carbon emission in coal mines.
