Abstract: In order to enable Hanjiacun Coal Preparation Plant to operate with control, management, decision-making and analysis work to be made all in an intelligent manner, and gradually achieve less and no human intervention, the transformation work is designed with the focus on the aspects of basic platform, basic automation, and intelligent control, management, decision-making and analysis. Practice shows that after technical transformation, the plant is made possible to realize autonomous learning and make dynamic predictions by collecting real-time operation data, shared data of systems, and through the use of the coal preparation expert knowledge base; and the loss of coal in refuse and consumption of flotation reagent are both reduced. The transformation work made has led to improved operating efficiency, reduced operating and management costs, and labor intensity, and improved working condition.
