Abstract: At present, the actual training of mine rescue teams mainly adopts the form of simulated roadway, which generally has problems such as low degree of simulation, fixed scene, high drilling cost, difficult assessment, and potential safety hazards. An online collaborative training system for mine rescue teams based on VR technology is designed. Virtual reality （VR） technology is used to present an advanced visual environment and simulate the disaster relief scene that cannot be simulated in the actual site, so that the rescue team can select appropriate rescue equipment according to its role division and disaster type under the condition of zero risk, and carry out mine map annotation, disaster area reconnaissance, rescue of people in distress, disaster disposal and other rescue tasks. At the same time, the system will conduct intelligent assessment and evaluation to find deficiencies and problems, better improve the commander’s comprehensive actual combat execution ability and collaborative combat ability. At the same time, in the process of system design, it is considered to give full play to the advantages of splicing large screen and ring screen, and introduce the referee and observation end to meet the needs of daily training, observation, competition and so on.
