Description

Technical Field

[0001] The present invention relates to the field of coal mine safety technology, and in particular to a method, device, electronic equipment and storage medium for managing rock burst disasters in a coal mine advance tunnel based on a yield tunnel. Background Art

[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 around the mining area. In the advanced tunnel facing the open space of the mining face, it is often the hardest hit area for rock burst 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.

[0003] In related technologies, the methods for managing coal mine rock burst disasters all focus on the self-decompression of the advance tunnel. For example, coal seam blasting decompression, large-aperture decompression, water injection decompression and roof pre-cracking are widely used measures on coal mine sites. These measures are complex to operate, prone to errors, and require a lot of manpower and material costs. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0005] To this end, the first purpose of the present invention is to propose a method for controlling rock burst disasters in coal mine advance tunnels based on yield tunnels. The yield tunnels 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 tunnels, thereby ensuring that the coal mine advance tunnels where pedestrians and vehicles pass are not damaged, reducing the risk of rock burst in coal mine advance tunnels, avoiding the risk of rock burst in coal mine advance tunnels, and ensuring safe production in coal mines.

[0006] The second purpose of the present invention is to propose a device for controlling rock burst disasters in coal mine advance tunnels based on yield tunnels.

[0007] A third object of the present invention is to provide an electronic device.

[0008] A fourth object of the present invention is to provide a non-transitory computer-readable storage medium storing computer instructions.

[0009] To achieve the above-mentioned purpose, the first embodiment of the present invention proposes a method for controlling rock burst disasters in a coal mine advance tunnel based on a yield tunnel, the method comprising:

[0010] Constructing a pressure relief roadway in the advance working face on one side of the advance roadway of the coal mine, wherein the pressure relief roadway is parallel to the direction of the advance roadway of the coal mine;

[0011] When the advance working face is mined, the yield roadway is used as a release channel for the advance stress of the coal mine advance roadway 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 roadway is protected from damage.

[0012] To achieve the above-mentioned purpose, the second embodiment of the present invention proposes a device for controlling rock burst disasters in a coal mine advance tunnel based on a yield tunnel, the device comprising:

[0013] A construction module is used to construct a pressure-relief roadway in an advance working face on one side of an advance roadway of a coal mine, wherein the pressure-relief roadway is parallel to the direction of the advance roadway of the coal mine;

[0014] 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.

[0015] To achieve the above-mentioned purpose, the third aspect embodiment of the present invention proposes an electronic device, comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions that can be executed by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute the method described in the first aspect.

[0016] In order to achieve the above-mentioned objectives, an embodiment of the fourth aspect of the present invention proposes a non-transitory computer-readable storage medium storing computer instructions, where the computer instructions are used to enable the computer to execute the method described in the first aspect.

[0017] The embodiment of the present invention provides a method, device, electronic device, and storage medium for managing rock burst disasters in coal mine advance tunnels based on a yield tunnel. A yield tunnel is constructed 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 risk of rock burst in the coal mine advance tunnel, avoiding the risk of rock burst in the coal mine advance tunnel, and ensuring safe production in the coal mine.

[0024] The following describes embodiments of the present invention in detail, 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 are not to 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 apparatus 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 controlling rock burst disasters in a coal mine advance tunnel based on a yield tunnel is provided in an embodiment of the present invention.

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

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

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

[0031] Furthermore, the construction parameters of the yield tunnel are the same as those of the mine's advanced tunnel. No support or reinforcement measures are taken, only to ensure that the tunnel does not collapse or close before the advanced working face is mined. The yield tunnel cannot be used for pedestrians, transportation, or 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 impose any specific limitation thereto.

[0035] Step 102, when the advance working face is mined, the yield roadway is used as a release channel for the advance stress of the coal mine advance roadway 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 roadway is protected from damage.

[0036] In some embodiments, the strength, stiffness, and support parameters of the coal mine advance roadway are set based on the damage parameters of the coal mine advance roadway when it is damaged to ensure that the coal mine advance roadway is not damaged. Therefore, the coal mine advance roadway should adopt high-strength, high-stiffness, and high-reliability support to ensure that the coal mine advance roadway 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, as shown in FIG. Figure 2 As shown, specifically, after determining the goaf of the advance working face, the goaf of the adjacent working face and the coal pillar of the working face, a pressure-yielding roadway is constructed in the advance working face on one side of the advance roadway of the coal mine. The pressure-yielding roadway is parallel to the direction of the advance roadway of the coal mine (advanced roadway), so that the advance stress and lateral stress can be released through the pressure-yielding roadway, thereby ensuring that the coal mine advance roadway where pedestrians and vehicles pass is not damaged.

[0039] Optionally, for a better understanding of the present invention, in the case of a plan view of a yield roadway, the present invention also proposes a schematic diagram of a yield roadway inclination profile (A-A'), which 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 embodiment of the present invention provides a method for managing rock burst disasters in coal mine advance tunnels based on a yield tunnel. A yield tunnel is constructed 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 pass is not damaged, reducing the risk of rock burst in the coal mine advance tunnel, avoiding the risk of rock burst in the coal mine advance tunnel, and ensuring safe production in the coal mine.

[0042] Furthermore, it should be noted that the present invention can also be applied to other tunnels with rock burst hazards, not just coal mine lead tunnels. This invention describes coal mine lead tunnels with advanced working face mining simply because they represent the most severe and representative areas of rock burst hazards in coal mines.

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

[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 rock burst disaster control device 40 based on the yield tunnel includes a construction module 41 and a release module 42.

[0046] A construction module is used to construct a pressure-relief roadway in an advance working face on one side of an advance roadway of a coal mine, wherein the pressure-relief roadway is parallel to the direction of the advance roadway 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 roadway is parallel to the coal mine advance roadway, and the horizontal distance from the coal mine advance roadway is twice the length of the plastic zone of the roadway 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 to, when excavating a yield tunnel, excavate the yield tunnel 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, wherein, when the advance working face is mined to the remaining length threshold of the yield tunnel, excavation of the next section of the yield tunnel is carried out.

[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 pass is not damaged, reducing the risk of rock burst in the coal mine advance tunnel, avoiding the risk of rock burst in the coal mine advance tunnel, and ensuring safe production in the coal mine.
