The utility model discloses a fully-mechanized coal mining retracement working face fan-shaped area supporting hydraulic support which comprises a movable base and an installation base arranged on the movable base, and the installation base is provided with a plurality of supporting parts, a synchronous adjusting mechanism and a positioning mechanism. Different from the prior art, when a worker carries out withdrawing work on a fully mechanized coal mining face, the supporting part is folded so that the device can be conveniently conveyed to a working position, after the device reaches the working position, the device can be rapidly unfolded to carry out supporting work, through arrangement of a positioning mechanism, a positioning plate can be adjusted on the uneven ground, and the working efficiency is improved. The fitting effect of the positioning plate and the ground is improved, and normal supporting use of the device is guaranteed. 本实用新型公开了一种综采回撤工作面扇形区支护液压支架，包括移动底座和设置在移动底座上的安装座，所述安装座上设置有多个支撑部，且设置有同步调节机
