The invention discloses a super large mining height hydraulic support with super high working resistance. The support comprises a base, a top beam and a shielding beam, wherein one end of the shielding beam is movably connected with the base through a connecting rod, while the other end is hinged with the top beam; an upright post is arranged between the top beam and the base; an equilibrium jack is arranged between the top beam and the shielding beam; and the upright post is a double telescopic upright post with cylinder diameter of phi 500mm. The front end of the top beam is provided with a telescopic beam; and the front end of the telescopic beam or the top beam is connected with a three level compound side protection mechanism. The top beam, the shielding beam and a rear connecting rod are provided with a movable side guard plate respectively. The hydraulic support can be applied to full-seam mining working face with super high coal seam of over 6.8m and has working resistance over 17,500KN, strength larger than 1.4MPa, central distance of 2,050mm, and maximum supporting height at over 7.0m. The support has simple structure, convenient use, safe operation, high efficiency of a coal protecting wall and high reliability, and is particularly suitable for mining super high coal seam.
