摘要
矿用空气幕的思想来源于民用建筑中的空气幕,高压空气幕以巷道中的压缩空气做气源,与一般空气幕相比,不需要专门的供风风机,不仅解决了供风风机给掘进司机带来的噪音问题,而且使得整套空气幕设备得以简化,减少了对掘进作业的影响;高压空气幕具有较好的隔尘效率,隔尘效率达到49.97%,对保护掘进司机免受粉尘危害具有重要作用。
The idea of mine air curtain comes from air curtain in civil building.High pressure air curtain regards the compressed air in the roadway as gas source,and it doesn't need special wind fans compared with the general air curtain,not only solves the problem of noise brought to tunneling driver,but also makes the complete set of air curtain simplified,reducing the influences of tunneling;high pressure air curtain has good dust-isolating efficiency,which can reach 49.97%,significant to protect tunneling driver from dust hazards.
