Advanced Detection System for Mine Rescue

In order to satisfy the actual needs of workers for the advanced detection of the roadway environment and to ensure the life safety of rescuers, a set of advanced detection system for mine rescue is developed. The paper studied and analyzed the key components of the system, such as gas-filled launcher, environmental parameter detection probe and receiver. The optimum launch strategy is determined in the restricted space of mine roadway by the analysis of the environmental parameter detection probe emission process based on air pressure and aerodynamics, and the actual test of the system is carried out in the coal mine roadway test site. The results showed that, the distance of the environmental parameter detection probe is greater than 50 m and there is no damage, the response time of sensor group is up to standard, the communication and data reception of receiver are normal. It can provide the environmental information for the rescue workers and decision-making basis for rescue guidance.
