依据有效压力平衡理论，在金川公司二矿区大断面巷道研究应用多机并联空气幕阻隔短路风流。试验结果表明：在断面和阻隔压差均较大的巷道内用空气幕替代风门可以收到理想的阻风效果，阻风率达８５ ％ ～８８ ％ ，且不影响行人和运输，具有推广应用价值。
Based on the theory of effective pressure balance, a multi-plane parallel air curtain was used to study the short-circuit airflow in the large-section roadway of Jinchuan No.2 Mine. The test results show that the ideal air resistance effect can be obtained by replacing air curtains with air curtains in tunnels with large cross-section and barrier pressure difference, with the blocking rate of 85% -88% without affecting pedestrians and transportation, so it has the advantages of popularization and application value.
