Abstract: In view of the present situation that the current mine rescue team mainly using medical human body model for medical emergency simulation training,which is too simple and idealistic.Computer 3D modeling,UGUI of Unity3D and message center communication technology were used to develop mine emergency medical treatment training system to achieve the purpose of medical first aid simulation training for complex injuries in complex environment.The overall design scheme and key technology of the system were introduced,that the visual and interactive operation of medical training can be realized.Through the using of the system,rescue personnel will be more familiar with the rescue medical emergency procedures,master first aid skills and improve the field first aid ability.
