Quantitative evaluation of carbon emissions with mining technology development: a case study of an iron mine in China.

To quantitatively evaluate the carbon emission effects of various underground mining schemes in metal mines, a carbon emission calculation model specifically for underground metal mines was established. The carbon emissions stemming from the mine's production process were categorized into three components: carbon emissions from the production of consumed materials, fuel, and electricity; carbon emissions resulting from fuel combustion and explosive explosions, and the reduction of CO absorption due to the occupation of the surface industrial site. Subsequently, the carbon emission impact of underground metal mines was assessed using an example from an iron mine in Anhui Province, China.
