Evacuation passage for single-hole drilling and blasting method tunnel and construction method of evacuation passage

The invention discloses an evacuation channel for a single-hole drilling and blasting method tunnel and a construction method thereof, and the evacuation channel for the single-hole drilling and blasting method tunnel comprises: a transverse channel, one end of which is connected with one side of the single-hole tunnel; and the lower end of the vertical shaft is connected with the other end of the transverse channel. According to the method, the requirement for arranging the evacuation channel in the single-hole drilling and blasting method tunnel can be met, a better solution is provided for evacuation and rescue of the single-hole drilling and blasting method tunnel under the limitation of topographic conditions, the escape path of personnel in the single-hole drilling and blasting method tunnel is increased, the safety, stability and emergency response efficiency of the evacuation channel are improved, and the evacuation channel can be used for evacuation and rescue of the single-hole drilling and blasting
