The invention relates to the technical field of a monomer hydraulic supporting pillar, and discloses a supporting base of a monomer hydraulic supporting pillar. The supporting base comprises a circular hoop; the lower end of the circular hoop is provided with three supporting legs, and the lower ends of the supporting legs are provided with bases; a fastening bolt is arranged on the hoop, and theinside of the hoop is provided with a liner; the liner is abrasive fabric. The supporting base delays the sinking of the hydraulic supporting pillar, prolongs the service life of the monomer hydraulicsupporting pillar, and plays good assistant supporting effect.
