[0002] A coal mine is an area where humans mine coal resources in coal-rich mining areas. Generally, it is divided into underground coal mines and surface coal mines. When the coal seam is far from the surface, generally, underground roadways are dug to extract coal, which is an underground coal mine. When the distance between the coal seam and the surface is very close, generally, the surface soil layer is directly stripped to excavate coal, which is a surface coal mine. During actual tunneling, generally, the roadway needs to be tunneled and supported.
[0003] When tunneling a coal mine, the use of a coal mine tunneling support device will be involved. However, most of the current coal mine tunneling support devices on the market are difficult to adjust, which affects the normal use of the coal mine tunneling support device. Therefore, the use efficiency of the coal mine tunneling support device is also reduced, and the working efficiency of the coal mine tunneling support device is also reduced. In view of the above problems, we have introduced a support device with an adjustment effect. Content of the Utility Model
