Abstract: The carbon peaking and carbon neutrality target requires the decarbonization and higher efficiency of the mining process in coal mines. In this paper, a coal-power flow coordinated optimal scheduling approach is proposed. First, based on the continuousness of coal flow in the work face, belt conveyor and silos, the coal delivery unit model is proposed to describe the relationship between coal delivery and nodal power injection. The coal delivery safety and power flow constraints are also integrated to derive the coal-power flow optimization model. To reduce the operation cost and carbon emission of coal mines, the real time carbon emission, the mining time slots, coal delivery velocity, delivery quantity and the units scheduling are optimized to obtain the optimal scheduling of the coal transportation and power system. To validate the effectiveness of the proposed method, simulations are conducted based on a real coal mine in Shanxi Province. Results show that the proposed model and method can effectively reduce the energy demand per ton coal production, the daily operation cost and the carbon emission. Hence the optimal low-carbon scheduling of the coal mine can be achieved with the proposed coal-power flow coordinated optimization approach.
