摘要：
Pressed ventilation in heading face is actually turbulent jet ventilation. In the blind drift, the air ducts are usually laid on one side of the drifting tunnel forming the wall-attached jet along the side of the tunnel and in order to dilute and pour out harmful gas and dust, and create an backflow at the same time, the airflow of the ventilation jet must reach at the head of the tunnel[1]. Therefore, the forced ventilation in heading face is actually restrained wall attached jet ventilation in confined space[2].
