Abstract: The preparation of a mine production continued plan is an important work of the mine production management and the core content. In the development engineering work, by using the theory and methods of operations research,we studied the simple and complex network of the development engineering, besides established the network diagram and digital model, finally development a visual network system through Java language,which can be using to get the methods of the development replacement.Combined with the actual project data of the FengHuangTai Mine,the result of the network system can be applied to the mines,which got praise.
