Abstract: The railway transportation system of the single mining block is a mixed dynamic system combined with a complicated dispersed incident and a continued incident. Thus according to the miscellaneity of the mine railway transportation process, the queuing network method and the mixed Petri net modeling technology were applied to the modeling and analysis on the railway transportation process in the single mining block. The model could well state the static attribute and the dynamic acti on of the mine railway transportation system in the single mining block and could provide a new method to the optimization dispatching and control of the mine railway t ransportation system.
