风幕(亦称空气幕)在国外已用于矿井通风的风量调节,我国一些科研、院校以及生产单位曾先后进行过风幕的试验研究。我局根据局属各矿山通风系统建设的经验教训,尤其是自动风门在压入式通风管理和使用中存在的问题,提出了把风幕由使用于风量调节扩大到截断风流代替风门的试验课题,1978年组成风幕试验组,在因民矿一坑、落雪矿一坑进行了工业试验。一年来,取得了一定成绩,在中、低风压区用风幕取代了风门。现将试验情况介绍如下: Air curtain (also known as air curtain) in foreign countries has been used for mine ventilation air volume adjustment, some of our scientific research, institutions and production units have conducted a wind curtain test study. According to the experience and lessons learned from the construction of ventilation systems in mines, especially the problems that automatic air doors have in the management and use of press-in ventilation, the paper proposes a pilot project to extend the air curtain from air volume adjustment to truncation of air flow instead of air damper , Wind curtain test group formed in 1978, due to a mine pit, a snowfall mine industrial test. In the past year, some achievements have been made and air curtains have been replaced by air curtains in medium and low pressure areas. Now the test conditions are as follows:
