Abstract: The preparation of a mine production continued plan is an important work of the mine production management and the core content would be a mining a nd excavation replacement plan.The mining and excavation replacement model of the coal mining face was firstly established with the systematic engineering analysis method, the numbering method and feature library content of the coal mining face and the coal mining team was set up and the integration of the mining and excavation replacement restraint conditions was summarized.Thus the mining and excavation inference process would be changed to a search process of the coal mining face acc ording to the restraint conditions.The mining and excavation replacement plan of the coal mining face was prepared.Therefore a excavation continued plan of the mine「 oadway was prepared according to the mining continued plan.Based on the circumstances, an advanced computer information technology, graphics processing technolo gy and module design were applied to the system design and to realize the computer automatic processing of the mine production continued plan and the continued pla n optimization.
