[0002] During the tunnel excavation process, accidents often occur. Generally, an emergency safety protection cabin is set in the tunnel as a temporary protection point. Due to the complex conditions of tunnel collapses, the rescue time for tunnel collapses is usually long. The oxygen demand of trapped personnel in the protection cabin is large, and the oxygen supply system in the protection cabin is required to supply oxygen to construction workers. However, a large amount of dust will enter the protection cabin in an instant after the tunnel collapse, so that although there is sufficient oxygen in the protection cabin, it will be mixed with dust and harmful gases, reducing the comfort of construction workers.
