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.
