In the process of mine exploration and production, energy consumption loads such as drilling rigs and ventilation are intertwined with building heating and hot water loads, and the mining area is rich in resources such as mine water waste heat and associated gas. Traditional energy scheduling methods are difficult to effectively deal with them. Therefore, an optimal scheduling model of mine integrated energy system (MIES) integrating photothermal power station and multi-source heat pump was proposed to improve energy efficiency and low-carbon level. The photothermal molten salt heat storage and multi-source heat pump group work together to build an electric-thermal collaborative supply network that adapts to the rhythm of mine production, and the multi-objective particle swarm optimization algorithm was introduced to optimize the economy and low carbon of the system. The results show that the weekly operating cost of the mine energy system is reduced to 331 700 yuan, the total carbon emission is 39.44 t, and the renewable energy consumption rate reaches 92.54%. The system effectively ensures stable heating in the mining area, with temperature fluctuations controlled within ±1.2 ℃. The utilization rate of the photothermal heat storage device reaches 92.17%, and the average coefficient of performance of the heat pump group rises to 4.47. The proposed model can fully integrate and utilize multi-energy sources in mining areas, effectively improving the economic and environmental benefits of the mine production system, and providing crucial technical support for the construction of green mines.
