Ezperimental modeling study on the reignition phenomenon when opening a sealed fire zone

摘要：

In view of reignition disaster when unsealing mine closed fire zone, thermokinetics model of reignition in goaf fire zone was created, reignition phenomenon after unsealing fire zone was simulated by experiment with self-made reignition simulation system and gas productions variation rule from enclosing to unsealing fire zone was tested. Results show that concentration of H2 and CO has the phenomenon of increasing instantly under the effect of second reaction; high concentration of H2 predicted reignition, which can be taken as a kind of index gas. The research results have a reference value for unsealing fire zone in coal mine.
