| 摘 要： | 依据有效压力理论和射流理论，导出单机和多机并联空气幕引射风流的有效压力理论公式。在矿山对多机并联空气幕的引射风流作用进行现场试验研究。结果表明，在大断面运输巷道内，多机并联空气幕可以有效控制风流的方向，起引射风机的作用，且不影响运输和行人，在矿山具有广阔的推广应用前景。 |
| 关 键 词： | 空气幕 有效压力 引射风流 大断面巷道 |

| Abstract: | According to the theories of effective pressure and air jetting,a theoritic formula for effective pressure of air flow ejected from air curtain by single fan or paralled fans was derived. A field test on the effect of the air flow from the air curtain by paralled fans was conducted in the mines. The results have shown that the air curtain from paralled fans was able to effectively control the air flow in large section tunnels and led to no obstruction of transportion and travellers. Therefore, it will have a wide range of prospects in mines. |
| Keywords: | air curtain effective pressure air jet large section tunnel |
