The invention belongs to an auxiliary mine tunnel construction device and particularly relates to a mining self-moving liftable scaffold. The mining self-moving liftable scaffold comprises an extensible operating platform, a liftable supporting device, a self-moving pushing device and a power source. The extensible operating platform utilizes bidirectional extensible cross beams to achieve movement of operating platform steel plates so as to meet the requirements of different cross sections construction platforms. The liftable supporting device utilizes extensible supporting legs to achieve a whole lifting function of the operating platform and meet the requirements for different construction heights and vehicle passing in a transportation roadway. The self-moving pushing device utilizes the extending bidirectional extensible cross beams to withstand two sides of the roadway and keep stability, and the supporting device is driven through the pushing device to achieve translation of the whole scaffold. The power source utilizes high-pressure water provided in a mine shaft to achieve self movement, lifting and extension of the device.
