The flexible and efficient operation of the transportation system requires precise coordination of supply, storage, and transportation among these components. However, the lack of connectivity and overall coordination between these components can easily lead to overfilled or empty surface and underground waste rock storage silos. Therefore, research on intelligent dynamic control methods for solid filling well's waste rock transportation system is imperative. Summary of the Invention
