掘进工作面长距离通风规律研究

Study of regulation of long distance ventilation in the case of tunnel digging

为了确保掘进工作面供风充足及安全掘进。本文介绍了实际工作面,计算了工作面的需风量,选择了相应风筒,并测算了风筒阻力和漏风率。结果表明,该风筒能够满足通风要求,为风机选型奠定了理论基础,对长距离通风工作具有重大的指导意义。

To ensure sufficient air supply to tunnel digging work place thus ensure safe execution of digging work, an appropriate air duct for ventilation is selected on the basis of calculation of air volume needed. The resistance in air duct and the air leakage rate are calculated to provide basis for fan type selection. The practice shows the air duct can meet requirement of ventilation. Successful experience is referential for the issue of long distance ventilation.
