Abstract: To improve the practical ability of disaster relief of mine rescue team and enhance the effect of routine training, the implementation plan of the mine rescue virtual simulation training system was designed based on the Unity 3D virtual reality development platform and the content of rescue drill. Firstly, using high quality modeling techniques to build rescue models and scenarios;secondly, on the basis of data management in the database, using the knowledge reasoning method based on time scale, the simulation and control of five kinds of dynamic disaster scenarios including fire, flood, coal and gas outburst, coal dust explosion and roof disaster were realized, IK bone control and organic state machine technology were adopted to realize system interactive control. Finally, a mine rescue drill virtual simulation system based on virtual reality technology was realized, which provided a reference for the application of simulation training technology in disaster rescue.
