This paper presents a hierarchical systems model, which integrates a simulator of the mine water use process with a multi-objective optimiser for assessing mine water management strategies. The simulator advances prior tools in simulating complicated strategies by placing operation rules on model objects and process states. An optimisation framework that interacts with the simulator is used to identify optimal strategies for water storage, use and reuse that are fit-for-purpose, easy to handle, and economic. The model has been used to assess mine water use strategies in a coal mine in Queensland, Australia. The simulation results indicate that some tested strategies could reduce water use costs by more than 40%, and raw water needed by more than 50%. Further, the optimisation revealed more easy-to-handle strategies that could save more than 40% of pipeline water and reduce the risks of penalties associated with discharge and of losing production due to insufficient water. We present an object-oriented system model for assessing mine water management strategies.The model combines the capabilities of water use process-based simulation and multi-objective optimisation.The system model can simulate complicated strategies by placing operation rules on model objects and process states.The system model can be used for investigating optimal strategy solutions that meet potentially conflicting objectives.A case study illustrates the value of the system model. |
