The upright of the hydraulic support for the mine is provided with a coating layer which is capable of enabling the upright of the hydraulic support for the mine to prolong service life. The technical scheme includes that the stainless steel coating layer is fixed on the surface of an upright body. The stainless steel coating layer is a steel pipe with an opening along the axial direction. The section of the steel pipe is in a circular shape. The section of the opening is in a long-strip shape. The steel pipe is made by bending cold rolling hard steel strip. The upright of the hydraulic support for the mine has the advantages of being capable of prolonging service life due to the fact that the stainless steel coating layer is fixed on the surface of the upright body, simple in whole structure and convenient to manufacture.
