Vertical shaft supporting system

The invention provides a vertical shaft supporting system which comprises an inner supporting barrel, a barrel-shaped air bag and an outer supporting barrel, the barrel-shaped air bag is arranged on the peripheral face of the inner supporting barrel in a surrounding mode, and the outer supporting barrel is arranged on the peripheral face of the barrel-shaped air bag in a surrounding mode. The vertical shaft supporting system is provided with the inner supporting barrel, the barrel-shaped air bag and the outer supporting barrel which are sequentially arranged from inside to outside in a sleeving mode, the outer supporting barrel makes contact with the rock mass, when the rock mass vibrates, the acting force of vibration acts on the barrel-shaped air bag through the outer supporting barrel, and on one hand, the barrel-shaped air bag plays a role in buffering displacement and deformation of the outer supporting barrel; and on the other hand, the vibration acting force is dispersed and then uniformly acts on the
