文中通过理论和实验研究,探讨了受限系数m=0.35～0.65之间轴对称和轴非对称的扁平型峒室采场风流出现附壁现象的机理,分析了附壁风流结构,指出扁平型峒室采场应分成三个不同的通风区域和两段不同的主风流,提出应用导风板控制附壁风流使其有利于峒室型采场通风,得出低压回流区长度的理论和经验计算公式,最后由实验验证了应用导风板控制附壁风流的可行性和有效性。
In this paper, through theoretical and experimental studies, the mechanism of the coalescence of the wind flow in the stopes with flat axisymmetric axisymmetric and axisymmetric between m = 0.35 ~ 0.65 is discussed. The wind structure of the attached wall is analyzed, The stope chamber should be divided into three different ventilation zones and two different main winds. The theory and experience of using the wind deflector to control the draft wind in the stope to make it conducive to the ventilation of the stope, Finally, the feasibility and effectiveness of applying wind deflector to control the wind flow in the annex are verified by experiments.
