摘要
介绍空气幕在金川公司二矿区、龙首矿和安庆铜矿大断面巷道内的应用情况。多机并联空气幕能有效阻隔短路风流、引射风流和增阻调节风流。在断面和阻隔压差均较大的巷道内用空气幕能替代风门阻隔风流 ,阻风率 85 %～ 88% ,替代风机站引射风流 ,风量 30～ 40m3/s ,或增阻调节风流。
The application of the gas curtain to the large section tunnel in 2 # mining field and Longshou Mine of Jinchuan Nonferrous Metals Corporation and Anqing Copper Mine are described The wind door, the blower station, and the wind window are substituted by the multiple gas curtain in the tunnels with large section and pressure differentials, the choking rate is up to 85%～88%, and the blowing rate to the strope is 30～40m 3/s, and the flowage in the tunnel is well adjusted It will be widely used in the underground mining
