The invention discloses an automatic gob-side entry retaining hydraulic support system, which comprises a plurality of hydraulic support groups and hydraulic props, wherein each hydraulic support group comprises a plurality of hydraulic supports which are arranged along the direction of gob-side entry retaining in sequence; each hydraulic support is provided with a support controller; the hydraulic props are arranged between tops and bases of the hydraulic supports; each hydraulic support is provided with two hydraulic props which are arranged in parallel with the direction of gob-side entry retaining. According to the gob-side entry retaining hydraulic support system, the support problem of the gob-side entry retaining can be safely and effectively solved; the support reutilization of the gob-side entry retaining is realized; material consumption is avoided; the support automation of the gob-side entry retaining is realized; single-action control, grouping control or automatic control can be carried out for supporting the hydraulic supports by the hydraulic support controllers; remote control is carried out for the supports by a monitoring host, a remote operating floor or a wireless remote controller, so that personnel safety is ensured; the labor intensity of workers is reduced; and the work efficiency is improved.
