本文针对柔性风筒供风特点及有关参数的内在联系,应用数学方法对实测资料进行了分析和综合,由此导出接近实际情况的供风参数。在此基础上对我国现有局部通风设备的选配问题进行了分析,为今后大断面巷道长距离掘进通风能力计算提供了若干依据。 In this paper, according to the inherent characteristics of the supply of wind and the related parameters, mathematical models are used to analyze and synthesize the measured data, and the wind supply parameters close to the actual situation are deduced. On this basis, the existing problems of the selection of local ventilation equipment in our country are analyzed, which provides some basis for the future calculation of the ventilation capacity of long-distance tunneling in large section tunnels.
