Optimization of production planning for underground metal mines based on market

According to the market environment and operational characteristics of underground metal mines, a market requirement planning model for mineral products was established by incorporating business intelligence (BI) with combination forecasting firstly. Based on the analysis results of the market requirement plamfing model, a mining-excavation planning model was constructed by using the theory and technology of multi-objective programming, expert systems, and time Petri nets extended with price information, and a calculation method to minimize the production cost was put forward. The calculation results of an underground metal mine show that the mining-excavation planning model can effectively optimize the production planning for the mining enterprise, help to achieve the purpose of enhancing the market competitiveness, and decline the operation cost.
