Outline
China's mining industry generally has the problems of high carbon emission intensity and extensive energy consumption. At present, mining is still in the theoretical level of carbon emission accounting, and there is a lack of unified management and analysis of carbon emission in the process of mining production. In view of the current situation of carbon accounting in underground mining, the existing accounting methods were summarized, and the carbon emission prediction and measurement model was constructed by using the whole life cycle assessment method and the carbon emission coefficient method, combined with the mine production management data and process equipment and other parameters. Based on this, the MVC software architecture model was used to build a system platform of carbon emission accounting for underground mining, and the function decomposition and interface design were carried out according to the six main modules of production data entry, prediction model calculation, measured model calculation, data comparison accounting, carbon perspective analysis and basic data management. Through the example application of Chengchao Iron Mine, it is concluded that in addition to high-power and high-energy-consuming process equipment such as lifting and ventilation, transportation, support and pneumatic drilling equipment are all key carbon emission points, and the error between the predicted data and the measured value is less than 10%, which meets the accuracy requirements. It shows that the constructed system can effectively realize the prediction and data analysis of carbon emissions from underground mining. The research results have guiding significance for the subsequent carbon reduction work of the mine.
