3D environment underground metal mine is constructed by computer graphics and 3D simulation technology in virtue of virtual reality. Emergency hedge and rescue process is simulated dynamical y based on Unity3D development engine. 3D virtual simulation&safety rescue training system is researched and designed which has human-computer interaction function and is used for underground metal mine cooperated with Advanced Realtime Tracking system. High effective and low-cost safety education and training for miners is realized which is significant for emergency management, preventive action and risk assessment in mines.
