Abstract: This article proposes a scheme for mine multi-level automation drainage control system. Firstly, it builds the model of multi-level drainage system, and gets the objective function with optimal control theory, solves the optimal solutions by using dynamic programming method, so it can arrange the drainage plan reasonably and realize the coordinated control of multi-level pump-house. The operation results in Caozhuang Mine show that this system can optimize the drainage plan dynamically, reduce the faults of overflow effectively.
