A comparison of the energy consumption and carbon ...

Transportation accounts for 80% of open-cut coal mine carbon emissions. With regard to the energy consumption and carbon emissions of transportation within an open-cut mine, this paper systematically compared the work and energy consumption of a truck and belt conveyor on a theoretical basis, and constructed a model to calculate the energy consumption of open-cut mine transportation.
