摘要
矿山井下的作业空间狭小，作业过程中产生的废气污染倍受关注。论文在某矿的主要运输中段应用多机并联空气幕将地表约40m^3·s^-1的新鲜风引射到该中段，有效控制了作业区的污风循环，降低作业区的风温5℃～10℃，不仅显著改善作业区的作业环境，保护工人的身体健康，而且有利于提高柴油机设备的运行效率和矿山的安全生产。
In this paper, air cuetain with multi-parallel fans was employed at major transportations in a mine of China to blow fresh air into this midsection at about 40m^3· s^-1. The polluted air circulation in the work zone was effectively controlled, and the air temperature in the work zone was decreased by 5～ 10℃. It was found that air curtain could not only improve the working environment, protect workers＇health, but also increase the operating efficiency of diesels, all of which proved to be conducive to mine production safety.
