Background

The hydraulic support is a structure used for controlling the mine pressure of the coal face. The mining face mine pressure acts on the hydraulic support in the form of external load. In a mechanical system of interaction of a hydraulic support and mining face surrounding rock, if the resultant force of all supporting pieces of the hydraulic support and the resultant force of an external load of a top plate acting on the hydraulic support are exactly in the same straight line, the hydraulic support is very suitable for the mining face surrounding rock, and the coal mine is extremely important to keep normal mining relation, but the coal mining technology has been developed for a long time for many years, and the top plate temporary supporting technology in the tunneling process is closely related to the construction speed. At present, various temporary support devices and technical means are available, and some temporary support devices cannot adapt to the field environment of loose bottom plates and loose coal and gangue covered by the bottom plates; some supporting devices can adapt to severe construction environments, but have small supporting capacity, cannot meet the requirement on the supporting strength of the top plate, or cannot control the supporting action point of the top plate, so that the supporting effect on the top plate is not ideal; there are also roof fractures caused by multiple repeated supports of the roof. In a word, the existing coal mine tunneling temporary support technology is still relatively laggard, and compared with mechanical equipment for coal seam cutting and permanent support construction, the temporary support technology and equipment are still quite laggard as matching technology and equipment, so that the existing coal mine has urgent requirements on the advanced fully-mechanized tunneling temporary support technology and equipment, and the requirements are directly related to the construction speed and the personal safety of site construction operators.
