降低建设矿井生产性构筑物的造价和缩短它们的工期有重要的国民经济意义。解决这个课题的最现实和最有前途的方法之一是,在改建通风系统时采取新的主扇布置方案并使用转换式的反风装置。1985年在库兹巴斯拉皮切夫斯卡娅矿井投入使用的就是最早的这种设备之一。这套设备是库兹涅茨克设计院根据BП-25型风机设计的。拉皮切夫斯卡娅矿井压入式通风设备的反风装置,是一个安装在通风钻井上的,能转 Reducing the cost of building productive structures in mines and shortening their duration have important national economic implications. One of the most realistic and promising ways to solve this problem is to adopt a new main fan arrangement and use a transformable anti-wind device when retrofitting the ventilation system. One of the earliest such devices was put into service in Kuzbass Lapischevskaya mine in 1985. The equipment is designed by the Kuznetsk Design Institute based on the BП-25 fan. Lapischevskaya mine ventilation equipment, anti-wind device, is installed in a ventilation drilling, can turn
