Description

Technical Field

[0001] The utility model relates to a stabilizing device for mining support, belonging to the technical field of mine tunnel support. Background Art

[0002] Mining support mainly refers to mine tunnel support. During the mining process, the rock strata will deform due to force, causing the tunnel structure to deform or be damaged, and even causing tunnel collapse. The role of mining support is to ensure the stability of the tunnel structure and prevent tunnel collapse accidents caused by rock deformation. Mining support must take effective support measures for deformed rock mass to ensure the safe production of minerals. The setting of the support structure can resist the disturbance caused by the deformation and volume change of the ore layer, thereby reducing the occurrence of production safety accidents.

[0003] The existing patent number is CN117211842A, which is a temporary support device for tunnels used in mining projects. This device includes a mounting seat, a pushing assembly, a support assembly, a booster rod, and a movable sleeve. The support assembly is installed on the mounting seat, and the pushing assembly moves in the movable sleeve to push the support assembly upward from the adjustment seat and insert it into the top of the tunnel. The booster rod has a telescopic effect, which can push both sides of the support assembly, which helps the support assembly to be connected to the top of the tunnel, effectively limits the position of the support assembly, and thus can stably support the top of the tunnel. However, when this device is in use, the support device at the top is set in a fixed form, which has certain limitations when in use and is difficult to quickly adjust according to the width of the mine tunnel; and when this device is in use, it is difficult to quickly splice multiple devices, which affects the integrity of the overall support structure in the mine tunnel, so that multiple support structures are staggered due to different squeezing of the mine tunnel, which is not conducive to the smooth support use in the mine tunnel.
