摘要

隧道多作业面平行施工时，其通风难度一般都比较大。以三都隧道进口工区为依托，分别对射流巷道式通风方案、主扇式通风方案及压入式通风方案从技术、经济2方面进行对比，分析通风方案的经济合理性；从理论上论述通风机的自动控制变频节能原理与节能效果，并经过工程实践及现场通风效果测试，达到了整个通风系统高效节能的目的。

Abstract

In normal cases, the ventilation for multiple tunneling faces is difficult. In the paper, comparison and contrast is made on jet flow gallery ventilation mode, main fan ventilation mode and forced ventilation mode in terms of technology and economical efficiency, with the ventilation for the entrance section of Sandu tunnel as an example. The economic rationality of the ventilation mode adopted is analyzed, the energysaving principle and energysaving effect of the automaticcontrolled frequencyconversion of the ventilation fans are analyzed theoretically. The ventilation practice demonstrates that the energysaving target has been achieved. 

Key words： parallel gallery; multiple tunneling faces; construction; ventilation; energysaving; jet flow gallery ventilation; mainfan ventilation; automaticcontrolled system
