Self-circulation type advanced hydraulic support

The invention relates to an advanced support device of a coal mine fully mechanized mining working surface lane, in particular to a self-circulation type advanced hydraulic support. The self-circulation type advanced hydraulic support consists of a walking part, a frame part and a plurality of support parts, wherein, the frame part is arranged on the walking part and can be telescopic and supportthe support parts for walking, and a plurality of support parts are supported in the lane; when the self-circulation type advanced hydraulic support needs to be moved forward, the manual handling is unnecessary, only the support parts need to be contracted for being supported on the frame part, the walking part advances and then the support parts are well supported. The self-circulation type advanced hydraulic support can improve the safety of a support environment of the fully mechanized mining working surface ventilation lane, reduce the labor intensity of miners, improve the support speed of a fully mechanized mini
