摘　　要：针对14行主回风井突然发生大面积垮塌后主斜坡道1150～1000中段出现严重风流反向、1000运输水平新鲜风流无法进入的严重情况，二矿区应用有效压力理论，借鉴国内外新鲜风流不能到达工作地点的空气幕引射风流技术，采用多机并联空气幕引射风流，有效地控制了主斜坡道1150～1000中段的反风现象，解决了1000运输水平没有新鲜风流的问题，安装空气幕后，主斜坡道进风量达到了45m3／s，确保了井下风流的正常流动，有利于保护井下作业人员的身体健康和安全生产，在矿山具有广阔的推广应用前景。In view of the emergency after the 14 line main ventilation shaft collapsed suddenly, the airflow disordered in No. 2 mine of Jin Chuan Group Ltd. , the main ramp 1150- 1000m of a serious reverse airflow, and fresh draft inaccessible transported to 1000 level, the No. 2 mine used efective pressure mechanism, adopted Air Flow Ejected From Air Curtain by Paralleled Fans. It has effectively controlled anti - wind of the main 1150 - 1000m ramps, and solved the fresh airflow problem of the 1000m transport level. After the scenes of the installation of air curtain, the fresh airflow of main ramp comes to 45m3/s to ensure that the normal flow of underground airflow, and it is very useful for the underground operations, health and safety, which willing have broad application prospects in mine.
