The present invention relates to the technical field of entry supports, and discloses an asymmetrical anchor beam support structure of a gob-side entry roof. An embedded steel seat of the asymmetricalanchor beam support structure is embedded in an embedded groove wall at the top of an entry and filled with high-pressure injected slurry, and thus the embedded steel seat has certain pre-tighteningforce; through arrangement of the embedded steel seat, the stability of an asymmetric support can be effectively improved, the problems of deformation and displacement during excessively large stressor concentrated stress are prevented, and the stability and safety of the support are guaranteed; the bottom of the embedded steel seat of the asymmetrical anchor beam support structure upwards extends into a connecting mechanism arranged in the embedded steel seat, the connecting mechanism penetrates through a hole of the support roof, the bottom of the connecting mechanism is connected to a structural steel inclined strut, the connecting mechanism and the structural steel inclined strut are integrally connected through anchor rods and anchor cables, and thus the stability and safety of the whole asymmetrical support structure are guaranteed; and the embedded steel seat of the asymmetrical anchor beam support structure adopts the arched top cross section, and the support performance and support stability of the embedded steel seat can be effectively improved.
