Research and modeling on flow of coal mine emergency plan based on Petri net

This paper has studied the flow of emergency plan for coal mine on the basis of Petri nets technology. Depending on the analysis of coal mine emergency response process, the theoretical framework of emergency plan has been established as well as the emergency business process of real world. Then, by using of Petri nets modeling technology, workflow modeling of coal mine emergency plan is established, and systematization of coal mine emergency rescue process is achieved. All the work has provided positive guidance for the coal mine emergency rescue.
