Abstract: The emergency plan is a work plan to ensure the rapid,orderly and effective implementation of control and rescue operations against the emergencies that have occurred or may occur. It mainly addresses the four issues of “what to do before the occurrence of emergencies,what to do during the occurrence of emergencies,what to do after the occurrence of emergencies,and who will do the above work”. Saida Gas has established a set of practical,reliable and efficient gas emergency management system based on the established 3D information system,combined with 3D virtual simulation technology and 3D GIS technology according to the actual demand,which provides a simulation scene for drilling personnel and a scientific basis for training assessment. The completion of the system has realized the digitalization of Saida Gas emergency plan management,clarified the work division,responsibilities and tasks of rescue personnel,improved the work efficiency and training ability of emergency rescue,and facilitated the evaluation,improvement and perfection of the emergency plan.

Key words: emergency plan, digital management, 3D information system
