[0002] Coal mine rock burst disaster is a dynamic phenomenon characterized by sudden, rapid and violent destruction caused by the release of deformation energy of coal mine shafts and coal rock masses around the mining area. In the advanced tunnel facing the empty space of the mining face, due to the combined influence of the lateral support pressure of the goaf of the adjacent mining face and the advance support pressure of the working face, the advanced tunnel is often the hardest hit area for rock burst.

[0003] In the relevant technologies, the methods for managing coal mine rock burst disasters all focus on the self-decompression of the advance tunnel, such as coal seam blasting decompression, coal seam large-aperture decompression, coal seam water injection decompression and roof pre-cracking, which are widely used on-site in coal mines. The operations are complicated, prone to errors, and require a lot of manpower and material costs. Summary of the invention

[0024] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] It should be noted that the acquisition, storage, use, and processing of data in the technical solution of this application comply with the relevant provisions of relevant laws and regulations.

[0026] The following describes, with reference to the accompanying drawings, a method and device for managing rock burst disasters in a coal mine advance tunnel based on a yield tunnel according to an embodiment of the present invention.

[0027] Figure 1 A schematic flow chart of a method for managing rock burst disasters in a coal mine advance tunnel based on a yield tunnel provided in an embodiment of the present invention.

[0028] like Figure 1 As shown, the method comprises the following steps:

[0029] Step 101, construct a pressure-yielding tunnel in the advance working face on one side of the coal mine advance tunnel, and the pressure-yielding tunnel is parallel to the direction of the coal mine advance tunnel.

[0030] In some embodiments, the yield tunnel is parallel to the coal mine advance tunnel, and the horizontal distance from the coal mine advance tunnel is twice the length of the plastic zone of the tunnel in the inclination direction of the advance working face.

[0031] Furthermore, the construction parameters of the yield tunnel are consistent with those of the coal mine advance tunnel, and no support and reinforcement measures are taken, only to ensure that the tunnel does not collapse and close before the advance working face is mined. The yield tunnel cannot be used for pedestrians, transportation and storage.

[0032] The construction parameters may include but are not limited to the height and width of the yield tunnel.

[0033] In addition, when excavating the yield tunnel, the yield tunnel is excavated in sections, and the excavation distance of each section is the influence length of the advance support pressure corresponding to the coal mine advance tunnel. Among them, when the advance working face is mined to the remaining length threshold of the yield tunnel, the next section of the yield tunnel is excavated.

[0034] The remaining length threshold of the yield tunnel may be 10 m, but is not limited thereto, and this embodiment does not make any specific limitation thereto.

[0035] Step 102, when the advance working face is mined, the yield tunnel is used as a release channel for the advance stress of the coal mine advance tunnel and the lateral stress of the goaf of the adjacent working face corresponding to the advance working face, so as to release the advance stress and lateral stress and ensure that the coal mine advance tunnel is protected from damage.

[0036] In some embodiments, according to the damage parameters of the coal mine advance tunnel when it is damaged, the strength, stiffness and support parameters of the coal mine advance tunnel are set to ensure that the coal mine advance tunnel is not damaged. Therefore, the coal mine advance tunnel should adopt high-strength, high-rigidity and high-reliability support to ensure that the coal mine advance tunnel is not damaged.

[0037] Among them, the pressure-relieving tunnel cannot be fully excavated at one time, otherwise it will collapse prematurely and fail to achieve the pressure-relieving effect.

[0038] In summary, the present invention proposes a plan view of a yield tunnel, such as Figure 2 As shown, specifically, after determining the goaf of the advance working face, the goaf of the adjacent working face and the coal pillars of the working face, a pressure-yielding tunnel is constructed in the advance working face on one side of the advance tunnel of the coal mine. The pressure-yielding tunnel is parallel to the direction of the advance tunnel of the coal mine (advanced tunnel), so that the advance stress and lateral stress can be released through the pressure-yielding tunnel, thereby ensuring that the coal mine advance tunnel where pedestrians and vehicles pass is not damaged.

[0039] Optionally, for a better understanding of the present invention, in the case of a yield roadway plan schematic diagram, the present invention also proposes a yield roadway inclination profile (A-A') schematic diagram, the yield roadway inclination profile sequentially includes the yield roadway, the working face coal pillar, the advance roadway, the working face coal pillar, and the adjacent working face goaf, such as Figure 3 shown.

[0040] Among them, Figure 2 Hehe Figure 3 In the figure, the black filling is the solid coal pillar of the working face, and the oblique line filling is the goaf.

[0041] The method for managing rock burst disasters in coal mine advance tunnels based on a yield tunnel in an embodiment of the present invention is to construct a yield tunnel in the advance working face on one side of the coal mine advance tunnel, and the yield tunnel is parallel to the direction of the coal mine advance tunnel; when the advance working face is mined, the yield tunnel is used as a release channel for the advance stress of the coal mine advance tunnel and the lateral stress of the goaf of the adjacent working face corresponding to the advance working face, so as to release the advance stress and lateral stress and ensure that the coal mine advance tunnel is protected from damage. Thus, the yield tunnel can release the advance stress and the lateral stress of the goaf of the adjacent working face corresponding to the advance working face through the yield tunnel, thereby ensuring that the coal mine advance tunnel where pedestrians and vehicles are traveling is not damaged, reducing the danger of rock burst in the coal mine advance tunnel, avoiding the danger of rock burst in the coal mine advance tunnel, and ensuring safe production in coal mines.

[0042] In addition, it should be noted that the present invention can also be extended to other tunnels with rock burst hazards, not just coal mine advance tunnels. The present invention uses the coal mine advance tunnels with advanced working face mining as the description object, simply because at the coal mine site, the coal mine advance tunnels are the most serious and representative areas of rock burst hazards.

[0043] In order to realize the above-mentioned embodiment, the present invention also proposes a device for controlling rock burst disasters in a coal mine advance tunnel based on a yield tunnel.

[0044] Figure 4 A schematic structural diagram of a device for controlling rock burst disasters in a coal mine advance tunnel based on a yield tunnel is provided in an embodiment of the present invention.

[0045] like Figure 4 As shown, the coal mine advance tunnel impact ground pressure disaster control device 40 based on the pressure-yielding tunnel includes a construction module 41 and a release module 42.

[0046] A construction module is used to construct a pressure relief tunnel in the advanced working face on one side of the advanced tunnel of the coal mine, wherein the pressure relief tunnel is parallel to the direction of the advanced tunnel of the coal mine;

[0047] The release module is used to use the pressure relief tunnel as a release channel for the advance stress of the coal mine advance tunnel and the lateral stress of the goaf of the adjacent working face corresponding to the advance working face when the advance working face is mined, so as to release the advance stress and lateral stress and ensure that the coal mine advance tunnel is protected from damage.

[0048] Furthermore, in a possible implementation of an embodiment of the present invention, the yield tunnel is parallel to the coal mine advance tunnel, and the horizontal distance from the coal mine advance tunnel is twice the length of the plastic zone of the tunnel in the inclination direction of the advance working face.

[0049] Furthermore, in a possible implementation of an embodiment of the present invention, the construction parameters of the yield tunnel are consistent with those of the coal mine advance tunnel, and no support and reinforcement measures are taken, only ensuring that the tunnel does not collapse and close before the advance working face is mined.

[0050] Furthermore, in a possible implementation of an embodiment of the present invention, the excavation module is used for excavating a pressure-yielding tunnel in sections, and each section excavation distance is the influence length of the advance support pressure corresponding to the coal mine advance tunnel, wherein when the advance working face is mined to the remaining length threshold of the pressure-yielding tunnel, the next section of the pressure-yielding tunnel is excavated.

[0051] Furthermore, in a possible implementation of an embodiment of the present invention, the strength, stiffness and support parameters of the coal mine advance tunnel are set according to the destruction parameters when the coal mine advance tunnel is destroyed to ensure that the coal mine advance tunnel is not destroyed.

[0052] The coal mine advance tunnel rock burst disaster control device based on the yield tunnel of the embodiment of the present invention constructs a yield tunnel in the advance working face on one side of the coal mine advance tunnel, and the yield tunnel is parallel to the direction of the coal mine advance tunnel; when the advance working face is mined, the yield tunnel is used as a release channel for the advance stress of the coal mine advance tunnel and the lateral stress of the goaf of the adjacent working face corresponding to the advance working face, so as to release the advance stress and lateral stress and ensure that the coal mine advance tunnel is protected from damage. Thus, the yield tunnel can release the advance stress and the lateral stress of the goaf of the adjacent working face corresponding to the advance working face through the yield tunnel, thereby ensuring that the coal mine advance tunnel where pedestrians and vehicles are driving is not damaged, reducing the danger of rock burst in the coal mine advance tunnel, avoiding the danger of rock burst in the coal mine advance tunnel, and ensuring safe production in coal mines.
