Abstract：With the proposal of the"double carbon"goal vision,the construction of a greenhouse gas monitoring system for the coal mining industry has become an inevitable trend.At present,the calculation of carbon emissions during coal mining was based on manual calculation of emission factors.The calculation method is mechanical,inefficient,and results have large errors,making it impossible to query daily and monthly reports of carbon emissions.Therefore,there is an urgent need to build a coal mine carbon emissions greenhouse gas monitoring system that can monitor,automatically calculate,and display information in real time.The carbon emission sources and accounting boundaries were analyzed during the coal mining process,the two major emission paths of the ventilation and extraction external discharge circuits of the coal mine carbon emission sources were determined,a carbon emission automatic accounting model was constructed based on continuous monitoring,and a coal mine carbon emission automatic monitoring and accounting system were developed.This system can automatically calculate the carbon emissions of coal mines,forming an integrated,informationized,and automated carbon emission management system of"real-time monitoring,automatic accounting,and graded reporting",providing technical support for enterprise level carbon emission accounting.
