An automatic support control method of a gob-side entry retaining hydraulic bracket comprises a single-action mode, a group control mode, an automatic control mode and a remote control mode, wherein the single-action mode comprises selection of a bracket, selection action and execution; the group control mode comprises selection function and execution; the automatic control mode is that the bracket automatically accomplishes action according to the preset combined control logic and execution target; the remote control mode is that control far away from the bracket is performed by a monitoring main machine, a remote operation station or a remote controller. The selection of the bracket is that the number of the bracket in need of operating in the group in which the bracket is arranged is input. The selection action is the independent action of selecting the bracket. The selection function is that the bracket performs the cooperation execution action according to the preset time sequence control logic. The support problem of the gob-side entry retaining is safely and effectively solved, the support of the gob-side entry retaining can be repeatedly utilized, and materials are not lost; the support automation of the gob-side entry retaining can be achieved, the support hydraulic bracket can be controlled by using a hydraulic bracket controller, the labor intensity of workers is reduced, and the working efficiency is improved.
