The invention relates to a ventilating panel, a ventilating assembly and a raise boring machine. The ventilating panel comprises a ventilating panel body, and an elastic part and a splicing part, which are arranged on the ventilating panel body, wherein the elastic part is connected with or is in resisting connection with the splicing part; the splicing part can move to insert into an outside mounting base under action of the elastic part, so that the ventilating panel body can be connected with the outside mounting base; under action of external force, the splicing part can overcome elastic force of the elastic part to drop out of the outside mounting base; and after external force is removed, the splicing part can be kept in a state of dropping out of the outside mounting base. Externalforce does not need to act on the splicing part all the time, the splicing part only acts the outside mounting base, and can be kept in the state. A condition that external force needs to act on a part for connecting the ventilating panel body to the outside mounting base when the ventilating panel body is dismounted is avoided, so that a dismounting process of the ventilating panel is relativelyconvenient, and using performance is improved.
