根据射流理论,提出了在工作面采用非稳态旋流通风的方法以控制工作面粉尘的扩散,改善室内工作环境,通过对非稳态旋流通风基本特性及控尘机理进行了分析,为工作面通风新方法的研究提供参考依据。
According to the jet theory, the method of unsteady swirling ventilation on the working face is proposed to control the spread of dust on the working face and improve the indoor working environment. The basic characteristics of swirling unsteady swirling flow and the mechanism of dust control are analyzed as Ventilation of the new method of study to provide a reference.
