Theory Model of Auxiliary Fans Being Installed in Two Sides of Cross-Cut of Tunnel and Application Investigation for Controlling Stagnant Air
It is generally difficult to install auxiliary fans in the frequent transporting tunnel. In allusion to such problems in transporting middle section as big regional ventilation resistance, reverse airflow and stagnant air etc., the effect of ejecting air flow by auxiliary fans being installed in tunnel was realized through ejecting air flow by auxiliary fans being installed in two sides of cross-cut of tunnel, which is come into being by parallel installing and running multi-fans in two sides of cross-cut of tunnel. The amount of ejecting air flow is above 45m3/s. Thus the technological difficult problem of adjusting and controlling air flow in the transporting tunnel was solved effectively. And homework environment are improved, workers health is protected, the visibility of driving in the lane is improved, which is favorable to production safety in the mine.
