The invention provides a tunnel frame type advance timbering structure and method, and belongs to the technical field of mine underground safe timbering. According to the method, single hydraulic props, Pi-shaped steel beams, semi-circular pipe hoops, steel (iron) tubes, steel plates (sheets) and bolts are mainly used for being connected and combined to form a transverse supporting structure and a longitudinal connecting structure which are used for advance timbering, conventional scattered timbering structures are connected to one another transversely and longitudinally to form a whole advance timbering structure, stability is improved greatly, the shortcoming that the traditional advance timbering structure only has effective timbering strength in the perpendicular direction, and is weak in deformation resistant ability in the horizontal direction and the longitudinal direction is overcome, when a rock burst disaster occurs, a safe space can be formed effectively, and safety of operators can be guaranteed powerfully.
