摘　　要：介绍了矿井风流调控的传统方法及矿用空气幕的布置形式,并将安装在巷道侧壁硐室内、具有柔性风门隔断风流、柔性风窗增阻减少风流和硐室型辅扇或风机机站引射风流作用的矿用空气幕定义为硐室型风流调控装置。现场应用研究结果表明,柔性风门的风流隔断率可以达到85%～88%,柔性风窗可有效对运输巷道中风流进行增阻,硐室型辅扇或风机机站的引射风量可达到30～40m3/s,在难以设置风门、风窗、辅扇和风机机站的运输巷道中能有效控制风流短路、风流反向、风流循环、增加或减少巷道风量等,这不仅可以强化中段通风网络的排烟排尘效果,保护工人的身体健康,而且有利于提高矿井的有效风量率,促进矿井风流有序流动。具有广阔的推广应用前景。The traditional methods of airflow controlling and the layout forms of mine air curtain are introduced. It defines cavern type airflow control device-the mine air curtain, which is installed in the side chamber of mine tunnel, could cut off airflow as flexible damper, increase resistance to airflow reduction as flexible wind window, and eject airflow as cavern type accessorial fan or fan ventilator station. Field application results show that the airflow partition rate of flexible damper reaches 85 ^-88 ~. The flexible wind window can effectively increase airflow resistance in transport tunnel. The airflow ejected by cavern type accessorial fan or fan ventilator station reaches 30 -40 ma/s. In transportation tunnel where a damper, a wind window, an accessorial fan or a fan ventilator station are difficult to be set up, the cavern type airflow control device in mine can effectively control airflow short-circuit, airflow reverse and airflow cycle, increase or decrease of roadway ventilation. It can strengthen the blasting fume and dust exhaust through stage ventilation network, protect workers healthy, and improve the efficient ventilation rate to promote the mine airflow. The technology boasts wide application prospect.
