The invention discloses a mining telescopic support and a using method thereof. The mining telescopic support is formed by a tray, a top post, a supporting base, a sandglass hole, a chassis, a top post handle, a supporting base handle, a sand discharging opening and a bolt, wherein the top post is sleeved in the supporting base, the top end of the top post is provided with the tray, the bottom part of the supporting base is provided with the chassis, and the top post is internally filled with sands in advance. The sands in the supporting base can be discharged through adjusting the amount of the sands entering into the supporting base and rotating the bolt on the supporting base, thus the height of the whole support can be changed, and the mutual coordination between the deformation of the support and the deformation of a roadway top plate can be met. The mining telescopic support disclosed by the invention has the characteristics that the structure is simple, the assembly and the disassembly are flexible and convenient, the bearing capacity is large, the supporting effect of the top plate is increased, and the like; and the mining telescopic support can be widely used for an underground working surface, different section roadways or tunnels and the like, which are in need of top plate supporting.
Description
technical field [0001] The invention relates to the fields of mining and geotechnical engineering support, in particular to a mine-used telescopic pillar and a method for using the same, which is suitable for roadway and tunnel roof support. Background technique [0002] Roof accident is one of the major disasters in mining engineering. Under the conditions of soft, broken, expansive surrounding rock and dynamic pressure, the temporary support forms commonly used in coal mine working faces mainly include: hydraulic props, friction metal props, spiral props, etc., although these support forms have significant However, they have the following defects to a certain extent: they need hydraulic sources such as emulsion, oil, and water pressure to supply power, high cost, complex structure, cumbersome support and withdrawal operations, and high labor intensity. Contents of the invention [0003] In order to overcome the disadvantages of existing temporary support technologies su...
