【摘要】：提出井下測風站應設在巷道風流的充分發(fā)展段,并以某矩形巷道為原型建立六個模型進行數(shù)值試驗。數(shù)值結(jié)果表明,進風順槽測風站合理位置距離轉(zhuǎn)彎處遠超10m;不同轉(zhuǎn)彎角度時進風順槽測風站的合理位置在距離轉(zhuǎn)彎處163~176m之后;模型3在計算表面粗糙度范圍內(nèi),測風站合理位置在距轉(zhuǎn)彎處144~177m之后。
[Abstract]:It is pointed out that the underground wind measuring station should be located in the fully developed section of roadway air flow, and six models should be established to carry out numerical experiments based on a rectangular roadway. The numerical results show that the reasonable position of the inlet wind measuring station is far more than 10 m from the turning point, the reasonable position of the inlet wind along the trough wind measuring station is after 163 鈮，
