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。
提齣井下測風站應設在巷道風流的充分髮展段,併以某矩形巷道為原型建立六箇模型進行數值試驗。數值結果錶明,進風順槽測風站閤理位置距離轉彎處遠超10m ;不同轉彎角度時進風順槽測風站的閤理位置在距離轉彎處163~176m之後;模型3在計算錶麵粗糙度範圍內,測風站閤理位置在距轉彎處144~177m之後。
제출정하측풍참응설재항도풍류적충분발전단,병이모구형항도위원형건립륙개모형진행수치시험。수치결과표명,진풍순조측풍참합리위치거리전만처원초10m ;불동전만각도시진풍순조측풍참적합리위치재거리전만처163~176m지후;모형3재계산표면조조도범위내,측풍참합리위치재거전만처144~177m지후。
The air measuring station of mine airway should be located in the fully developed region is proposed and numerical tests are conducted based on six models with a coal face as a prototype .The results show that ,the distance between the reasonable location of air measuring station in head entry and the turning corner is much more than 10m .The reasonable location of air measuring station in different turning angles is 163~176m after the turning corner .In calculation the range of roughness heights of model 3 ,the reasonable air measuring station should set after the turning corner of 144~147m .
