摘要
The powder jetting performance and the jetting rate were analyzed,and the jetting pressure was studied under different amount of explosion suppressant agent,different length and number of high pressure nozzles as well.The technical parameters of active explosion suppression system were tested and verified.The results showed that the suppression barrier forming rate was 0.024 m/ms,the roadway of 6.25 m2 section area could be filled in 100 ms after the system was triggered.The longer the side distance was,the quicker the jetting pressure released.The formulation was obtained to calculate the amount of explosion suppressant agent for the unit area.The jetting rate was higher than 90% which can enssure a satisfied explosion suppression effect.
