摘要
介绍用气幕降尘系统解决机掘工作面的粉尘和瓦斯问题。从理论上探讨了气幕降尘系统的有关工艺参数；从实验上验证了气幕降尘系统的可行性，并展望了气幕降尘系统在煤矿的应用前景。
The dust suppression system with air curtain was first proposed to solve the problem of dust and gas in mechanized heading faces in this paper.The technical parameters relating to the system were inquired in theroy and the feasibility of the system was demonstrated by experiments.The future application of the system in coal mines was prospected.
