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 planning model,a miningexcavation 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 efectively optimize the production planning for the mining enterprise,help to achieve the purpose of enhancing the market competitiveness,and decline the operation cost.
