焦家寨煤矿矿井通风系统探讨

对焦家寨煤矿矿井通风系统的探讨得出结论:该矿井通风系统改造后,矿井总进风量为13916m3/min,其中主立井进风量为3 513 m3/min,副立井进风量为9 581 m3/min,进风平硐进风量为822 m3/min;矿井总回风量为14 893 m3/min,其中2号回风斜井回风量为6 720 m3/min,回风斜井回风量为8 173 m3/min;2号回风斜井及回风斜井通风容易时期及通风困难时期,均属于容易通风。

Probe into the Ventilation System of Jiaojiazhai Coal Mine

The exploration on the ventilation system of Jiaojiazhai Coal Mine comes to the conclusion that after the transformation of the ventilation system in Jiaojiazhai Coal Mine, the mine＇ s total supply air rate is 13 916 m3/min, in which the main shaft＇s supply air rate is 3 513 m3/min, the vice shaft＇s supply air rate is 9 581 m3/min, and the wind tunnel＇s supply air rate is 822 m3/min; the mine＇s total return air rate is 14 893 m3/min, in which No.2 return air inclined shaft＇s return air rate is 6 720 m3/min and return air inclined shaft＇s return air rate is 8 173 m3/min; and during both easy ventilation period and difficult ventilation period, the ventilation of No.2 return air inclined shaft and return air inclined shaft belongs to easy ventilation.
