Abstract: With the continuous development of information technology, the important development of emergency rescue at mine gradually pursues systematization, precision, intelligence and diversification.China's mines have invested extensively in information technology construction in the field of safety, and despite these efforts, they are still faced with complex and changing situations after mining accidents.During the on-site rescue process, it is often difficult to comprehensively capture all the information and develop an appropriate rescue plan.In this paper, a digital twin system for mine rescue environment(DTS-MRE)is proposed based on digital twin technology, and its overall architecture, functional features, and key technologies for system construction are introduced.The application of DTS-MRE is expected to assist the monitoring, modeling, simulation, coordination, prediction, and control of the whole process of mine emergency rescue governance, thus increasing the success rate of mine emergency rescue and providing scientific and technological support for mine safety emergency rescue.
