Automatically-circulating advanced hydraulic support

The utility model relates to an advanced support device of a coal mine fully-mechanized working face tunnel, in particular to an automatically-circulating advanced hydraulic support. The automatically-circulating advanced hydraulic support comprises a walking part, a frame part and a plurality of support components, wherein the frame part is arranged on the walking part and can rise and withdraw to support the support components to walk, and the plurality of support components are supported in the tunnel. When the support needs to move forwards, the support components just need to be withdrawn and supported on the frame part without the need of manual carrying, the walking part moves forwards, and the support components are then well supported. The utility model can improve the safety degree of the support environment of the fully-mechanized working face ventilation tunnel, lighten the labor intensity of miners, improve the support speed of the fully-mechanized working face and accelerate the coal production.
