Abstract: This paper systematically discusses the importance of multi-link coordination and optimal management in ensuring the efficient operation of the mine around the production plan deduction of open-pit coal mines. The production process of open-pit coal mines includes blasting, mining, washing, loading and other links, which involve multiple influencing factors, such as equipment efficiency, climate, equipment maintenance, etc., which makes it challenging to formulate a scientific and reasonable production plan. To this end, a set of “intelligent planning deduction interactive system” is constructed, which integrated output forecasting, production capacity analysis and multi-dimensional influencing factor evaluation in order to carry out forward and reverse deduction of production planning, providing reliable data support. The system first predicts the production capacity of electric shovels, trucks and other equipment by establishing a production capacity model, and then constructs an operation plan model for mining and stripping. Then, the gray theory model is used to improve the accuracy of output forecasting and ensure the reasonable allocation of production resources by combining uncertain factors such as truck failure and weather. In addition, the system also performs high-precision analysis of the production process of the coal washing plant, covering the steps of rough washing, fine washing, and slime recovery, and ensures the balance of coal quality and production capacity through dynamic simulation and parameter optimization. In the deduction of the loading station plan, the loading capacity is optimized through a fine-grained data model based on factors such as the sunroof period and equipment performance fluctuations, and the intelligent scheduling algorithm is used to improve the loading efficiency and smooth the output fluctuation. Through the integration of multi-level data processing and optimization models, the system provides scientific decision support in the whole life cycle of the open-pit coal mine, making the production process more efficient and stable. The deduction system not only improves the automation and intelligence level of production, ensures the safety and sustainability of production, but also lays a solid foundation for the realization of smart mine management.
