【摘要】：提出井下测风站应设在巷道风流的充分发展段,并以某矩形巷道为原型建立六个模型进行数值试验。数值结果表明,进风顺槽测风站合理位置距离转弯处远超10m;不同转弯角度时进风顺槽测风站的合理位置在距离转弯处163~176m之后;模型3在计算表面粗糙度范围内,测风站合理位置在距转弯处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，
