Abstract: Full-scale burning tests were conducted in a full-scale underground long corridor with beamed ceiling and smooth ceiling. The influence of air-supply opening position on the smoke exhaust efficiency was studied. The operation time of the smoke exhaust fan was also discussed to obtain a better smoke exhaust. Results showed that the smoke exhaust would be more efficient when air-supply openings were some distance away from the smoke exhaust openings. When the air-supply opening was near the smoke exhaust opening, even with larger smoke exhaust rate, it still gave poor smoke control results. Two comparing tests on the effects of operation time indicated that it would give poor smoke control ability when the smoke exhaust system operated too early. Finally, some future research topics were also discussed in this paper.
