为了研究掘进巷道发生火灾封闭后的内部情况，采用FDS数值模拟研究了火区内各参数的变化规律，包括Co浓度，o2浓度，风压变化，温度变化等，研究表明，火源附近Co最大达0.2%，火区封闭前最大风压为23pa，封闭火区后风压骤增，最高达650pa。
為瞭研究掘進巷道髮生火災封閉後的內部情況，採用FDS數值模擬研究瞭火區內各參數的變化規律，包括Co濃度，o2濃度，風壓變化，溫度變化等，研究錶明，火源附近Co最大達0.2%，火區封閉前最大風壓為23pa，封閉火區後風壓驟增，最高達650pa。
위료연구굴진항도발생화재봉폐후적내부정황，채용FDS수치모의연구료화구내각삼수적변화규률，포괄Co농도，o2농도，풍압변화，온도변화등，연구표명，화원부근Co최대체0.2%，화구봉폐전최대풍압위23pa，봉폐화구후풍압취증，최고체650pa。
in order to study the internal ifre Roadway after the closure, change law of every parameter in the ifre area was studied by using FDS numerical simulation, including Co concentration, o2 concentration, the change of wind pressure, the results indicate that the temperature changes, the maximum reached 0.2%CO, near the ifre source, ifre closed before the maximum wind pressure is 23pa, after the closed ifre zone pressure surge, up to 650pa.
