摘要
Abstract
To prevent the discharge of harmful gases in the through-lane caused by negative pressure ventilation, the scheme of setting and filling original through-lane isolation belt and the sealing of surrounding rock fissure are carried out based on the in-stallation of through-lane isolation belt and the sealing of the surrounding rock fissures. The research results show that under the premise of detecting the specific information of the through-lane sealing and without destroying the original sealing, the through-lane isolation belt setting and sealing surrounding rock fissures can be used to ensure that the harmful gas in the tunnel will not overflow under the action of negative pressure ventilation.关键词
