摘要:
地下洞室开挖过程中,用局部通风改善独头工作面大气质量的方式非常普遍。本文从能耗、阻力、送风量、送风距离和成本等方面定量分析了使用大直径风筒在地下洞室独头掘进通风系统中的优点,并指出在现场条件适宜的情况下应尽可能选用大直径风筒。采用大直径风筒是改善独头工作面通风效果的有效方法之一。

Abstract:
In underground cavern excavation, it is a common practice to install local ventilation systems so as to improve the air quality at the singleend working faces. quantitative analysis is made on the advantages of the application of largediameter ducts in the singleend driving ventilation of underground caverns in terms of energy consumption, resistance, air volume, ventilation distance and cost. Conclusion is drawn that largediameter ducts should be used as far as possible when the site conditions are suitable and that application of largediameter ventilation ducts is one of the effective means to improve the ventilation effect at the singleend working faces.
