[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model provides a mine tunnel support device, such as Figure 1-5 As shown, the mine tunnel support device includes: a support plate 1 symmetrically arranged in the mine tunnel 17 for support; an electric hydraulic rod 2 for adjusting the height, the electric hydraulic rod 2 is fixedly mounted on the support plate 1; an assembly block 3, the assembly block 3 is fixedly mounted on the top of the output rod of the electric hydraulic rod 2, and a detachable plug-in block 4 is arranged on the assembly block 3; an assembly plate 5, the assembly plate 5 is fixedly mounted on the top of the plug-in block 4; a plurality of support columns 6, a plurality of the support columns 6 are fixedly mounted on the top of the assembly plate 5, and a support plate 7 for supporting the roof of the mine tunnel 17 is fixedly mounted on the top of the support column 6; a dust removal mechanism for suction and dust removal, the dust removal mechanism is arranged on the support plate 1 and the assembly plate 5.

[0023] It should be noted that the installation of supporting and protective structures is an important and time-consuming task during the excavation of mine tunnels. Traditional plate structures require a large number of support rods for tightening, which means that the installers need to perform tedious operations such as carrying, positioning, and tightening in the narrow tunnel space. These steps not only increase the complexity of installation, but may also lead to longer installation time; in addition, each step in the installation process requires precise control to ensure that the support rods can be evenly distributed on the tunnel roof and side walls to form effective support force. However, due to the limitations of the tunnel environment and the errors of manual operation, it is difficult to ensure that each support rod can be accurately installed and tightened, which further increases the difficulty and time-consuming of installation; the geological conditions of mine tunnels are complex and changeable, including different rock types, joint development, groundwater conditions, etc. These geological factors will directly affect the stability and safety of the tunnel. Traditional plate structures often adopt unified support parameters and designs, which are difficult to adapt to the tunnel support needs under different geological conditions; for example, in tunnels with broken rocks and developed joints, the support effect of the plate structure may be poor, which can easily lead to tunnel collapse and deformation. In tunnels with abundant groundwater, the plate structure may be washed and eroded by water flow, further reducing its support effect. These problems may lead to failure of tunnel support and bring safety hazards to excavation work; due to the existence of the above two problems, traditional plate structures have certain safety hazards in mine tunnel support. The cumbersome and time-consuming installation process may hinder the progress of excavation work, while increasing the labor intensity and safety risks of workers. The difficulty in adapting to changing geological conditions may lead to poor tunnel support effects, prone to accidents such as collapse and deformation, posing a threat to the safety of workers' lives and property; therefore, in response to the problems existing in the existing technology, it is particularly important to develop a new type of mine tunnel support device;

[0032] In this embodiment, the bolts penetrate the plug-in block 4 through threads, firmly connecting the assembly block 3 and the plug-in block 4 together, avoiding loosening or displacement that may occur during tunnel excavation or support, and ensuring the stability of the entire support device; although the bolts play a fixing role, due to their detachable nature, workers can easily remove or reinstall the bolts to adjust the relative position between the plug-in block 4 and the assembly block 3 when necessary, thereby adapting to the needs of different tunnel supports.
