一、计算公式若掘进或回采时所需的风量为Q_1,在使用风管的条件下将漏风率计算在内所需的风量为Q_2,则风管内的平均风量Q==Q_1+Q_2/2,米~3/秒;风管内的平均流速
I. Calculation Formula If the air volume required for tunneling or recovery is Q_1 and the air volume required to calculate the air leakage rate when the air duct is used is Q_2, the average air volume in the air duct Q == Q_1 + Q_2 / 2 , M ~ 3 / s; average velocity inside the duct
