With the changes in mining conditions and the adjustment of production processes, the original ore distribution system and truck dispatching system have exposed problems such as single function and lack of coordination in terms of ore grade control and transportation safety. In order to optimize the production dispatching process of Nannihu molybdenum mine, a set of intelligent dispatching system upgrade solutions was proposed, which covered the switching of mining dispatching modes, ore loading and unloading control, excavator authority management and secondary ore distribution scheduling algorithm based on ore grade control. By constructing a two-layer framework of "static ore distribution before shift+secondary ore distribution correction", a secondary ore distribution method based on the target excavator influence coefficient model is designed to achieve the coordinated optimization of grade balance and transportation efficiency, and compress the daily grade fluctuation range to±0.003%. In addition, a multi-system collaborative linkage mechanism was proposed, which effectively solved the problems of illegal operation and traffic conflicts of outbound vehicles through RFID positioning, authority configuration and data feedback. The application results show that the system has stabilized the average daily output of the Nannihu molybdenum mine at 15 000 t (±1 000 t), and the ore grade meets the needs of the concentrator, providing a technical solution of dynamic response and multi-target coordination for the intelligent upgrade of mines under complex scenarios.
