Abstract: Through the statistics of research and application of VR in coal mine from all over the world, it was concluded that the application fields of VR in mine in status quo were mainly in three types: training, visualization and comprehensive application. Based on the differential of the input/output devices that used in the VR system, the current VR system in coal mine could be divided into three types: desktop-based and general input device, projector-based and customized input device, and head mount display-based and natural input device. The type used in China right now was mainly desktop-based and general input device, and the type used in the mature market all over the world was mainly projector-based and customized input device, while in the future, the head mount display-based and natural input device is the most suitable type for the VR system in coal mine. Considering the different VR technique application fields in coal mine, the key research aspects in the future were discussed. Based on the head mounted display and motion tracking device, an immersive and natural interactive VR mine training system was developed, and the effectiveness of this kind of system is validated.
