The invention discloses a protection device for vertical shaft tunnel blast construction. The protection device comprises a protection cover capable of being assembled and is characterized in that the protection cover capable of being assembled comprises I-shaped steel used for manufacturing a skeleton; the I-shaped steel is fixedly connected with a steel plate; the I-shaped steel and the steel plate form a half-open rectangular framework; and hoisting rings are arranged on the steel plate side by side. By hoisting and fixing the protection device before blast, sound insulation, noise reduction and flying rock protection can be achieved during blast, and the protection device can be pulled out and hoisted out after blast; construction is easy and convenient, and protection is safe and reliable; and the problem of harm of blast noise and blast flying rock to peripheral civil houses and personnel is effectively solved. 本发明公开了种竖井隧道爆破施工防护装置，所述防护装置包括可拼装防护罩，其特征在于：可拼装防护罩包括用于制作骨架的工字钢，所述工字钢上固定连接有钢板，工字钢与钢板形成半开口矩形框架，所述钢
