A METHOD AND A SYSTEM FOR MINE DEWATERING OPERATION

摘要

The invention relates to a method and a system for mine dewatering and ventilation operations. The method comprises steps of obtaining plant data in relation to mine dewatering and ventilation operation for model based control and optimization. A plurality of process models of plant units and devices are used in the mine dewatering and ventilation operation. An objective function is formulated for minimization of energy consumption in the mine dewatering and ventilation operation using the tuned plurality of process models and solved for determining set points for optimized mine dewatering and ventilation operation. The mining plant units and devices are controlled with DCS controllers and other controllers around the set points for minimized energy consumption in the mine dewatering and ventilation operation. A mine dewatering operation management system is also provided.
