Abstract: For rapid and highly efficient requirements of mine emergency handling and rescue, a mine rescuing support system was designed by analyzing environmental information in disaster scene and vital sign of rescuer. Composition of the system was introduced as well as design schemes of two detectors namely ahead underground environment detector and wearable vital sign equipment for rescuer. Rescuing support detecting method was expounded which was based on fusion analysis of vital sign of rescuer and underground environmental information. The test results show that the system realizes real-time monitoring and warning of rescuer status in rescue process and environmental condition in underground disaster scene, which ensures rescuer safety and improves rescue efficiency.
