[0002] Hydraulic fracturing technology for coal and rock masses has developed rapidly and has been widely applied in areas such as hard roof control, dynamic pressure roadway decompression, and hard roof coal weakening, significantly improving the safety of mine production. Currently, the most commonly used method is conventional shallow-hole hydraulic fracturing. This technique is typically performed close to the strata of the roadway to be treated, with a maximum borehole length generally not exceeding 60m. The boreholes are drilled at an angle and are numerous. However, during drilling, the fracturing equipment may encounter changes in formation hardness, causing equipment misalignment and leading to problems such as borehole wall breakage and borehole collapse. These issues affect the accuracy and integrity of the borehole, thus impacting the subsequent fracturing effect. Utility Model Content

[0025] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] like Figures 1-3 As shown, the support device for fracturing boreholes in roadway roofs according to this embodiment of the present invention includes: support component 1 and angle detection component 2.

[0027] The support assembly 1 includes a support body 11, which is fixed to the opening end of the fracturing borehole 400. The support body 11 defines a borehole detection zone 10. The fracturing drilling equipment 300 is used to drill a borehole 400 through the borehole detection zone 10 and into the roof 200 of the roadway 100. Angle detection assembly 2 is connected to the support body 11. At least a portion of the angle detection assembly 2 is placed within the borehole detection zone 10. The angle detection assembly 2 abuts against the outer peripheral wall of the fracturing drilling equipment 300 and extends along a direction orthogonal to the extension direction of the support body 11 (e.g., ...). Figure 1 The angle detection component 2 is movable in the vertical direction and is used to detect the tilt angle of the fracturing drilling equipment 300.

[0028] Specifically, such as Figures 1-3 As shown, the support body 11 can be fixed to the opening of the fracturing borehole 400 using bolts or other connectors to provide a reliable installation space for the angle detection assembly 2. The support body 11 can be made of a high-strength material (such as stainless steel) to withstand various forces during the drilling process. The central portion of the support body 11 defines a borehole detection area 10, which is a space used to detect and guide the drilling equipment to accurately drill the borehole 400.

[0029] Angle detection component 2 is connected to support body 11. Angle detection component 2 is used to detect and monitor the tilt angle of fracturing drilling equipment 300 in real time. Angle detection component 2 may include angle detection equipment (such as angle sensor, pressure sensor, etc.). A part of angle detection component 2 (such as equipment used for drilling 400) is placed in drilling detection area 10. The outer peripheral wall of fracturing drilling equipment 300 abuts against angle detection component 2, so that angle detection component 2 can adjust the position of drilling equipment 400 in real time according to the pressure or tilt angle of drilling equipment 400 during drilling process, so as to ensure the angle of drilling 400 and the continuity and smoothness of drilling wall surface.

[0030] Understandably, the angle detection component 2 can monitor the tilt angle of the drilling equipment 400 in real time, ensuring that the drilling 400 follows a predetermined path, thereby improving the accuracy of the drilling 400. Through the monitoring and adjustment of the angle detection component 2, the risk of borehole wall breakage and borehole collapse can be effectively reduced, improving the stability of the borehole 400. Therefore, due to the improved accuracy and stability of the borehole 400, the subsequent fracturing effect will also be enhanced, helping to better control the top plate 200 and achieve the purpose of pressure relief.

[0031] In other words, the support device for fracturing boreholes in roadway roofs according to this embodiment of the invention helps reduce safety risks during construction by ensuring the accuracy and stability of the borehole 400. The use of the angle detection component 2 can reduce rework caused by borehole 400 deviation, thereby improving construction efficiency. It can also adapt to changes in the hardness of different strata, ensuring effective fracturing borehole 400 construction under various geological conditions.

[0032] In some embodiments, there are multiple angle detection components 2, which are arranged symmetrically around the centerline of the support body 11. It is understood that, as Figures 1-3 As shown, the extension direction of the centerline of the support body 11 is... Figure 1 The vertical direction is consistent. Multiple angle detection components 2 are symmetrically arranged on the left and right sides of the center line of the support body 11, and all multiple angle detection components 2 abut against the outer wall surface of the drilling 400 equipment, so as to enable real-time monitoring of the drilling 400 equipment at different positions and further improve the accuracy of the drilling 400 equipment.

[0033] In some embodiments, the angle detection component 2 includes a plurality of angle detection units 21, the plurality of angle detection units 21 includes a plurality of detection unit groups, the plurality of detection unit groups are arranged at intervals along the extension direction of the support body 11, and a detection unit group includes a plurality of angle detection units 21, the plurality of angle detection units 21 in a detection unit group are arranged at intervals along the extension direction orthogonal to the extension direction of the support body 11.

[0034] Specifically, such as Figures 1-3 As shown, the angle detection component 2 consists of multiple angle detection units 21, each capable of detecting the tilt angle in a specific direction. Multiple detection units are arranged sequentially to form a detection plane, increasing the contact area between the angle detection component 2 and the drilling 400 equipment. Optionally, the cross-sectional outline of one angle detection component 2 can be rectangular (e.g., ...). Figure 3 (As shown), it can also be circular. Of course, the number and arrangement of the angle detection units 21 can be adjusted adaptively according to different drilling equipment.

[0035] Understandably, arranging multiple angle detection units 21 within an angle detection component 2 enables more precise monitoring of the tilt angle. Each angle detection unit 21 can independently monitor the tilt angle of the drilling rig 400. The collaborative work of multiple detection units improves the response speed to changes in the tilt angle of the drilling rig 400, allowing for rapid adjustments once an anomaly is detected. Therefore, the angle detection component 2 can provide more refined and comprehensive tilt angle data, enabling more accurate control of the drilling rig 400's orientation, thereby improving construction accuracy and drilling quality.

[0036] In some embodiments, the angle detection component 2 further includes a plurality of elastic elements 22, which correspond one-to-one with a plurality of angle detection units 21. In the extending direction of the angle detection unit 21, the elastic element 22 is connected between the angle detection unit 21 and the support body 11.

[0037] Specifically, such as Figures 1-3 As shown, one end of the elastic element 22 abuts against the angle detection unit 21, and the other end of the elastic element 22 abuts against the support body 11. When the drilling equipment 400 passes through the support body 11, the angle detection unit 21 can abut against the outer peripheral wall of the drilling equipment 400 under the elastic force of the elastic element 22, so that when the drilling equipment 400 shifts, the angle detection unit 21 can be compressed or stretched by force, thereby determining the distance of the shift of the drilling equipment 400.

[0038] It is understandable that, such as Figures 1-3As shown, if the drilling 400 device is tilted to the upper right, the angle detection component 2 on the right side will be squeezed, and the elastic element 22 will be compressed. Conversely, the angle detection component 2 on the left side can always resist the drilling 400 device under the elastic force of the elastic element 22.

[0039] Therefore, the elastic element 22 acts as a buffer between the angle detection unit 21 and the support body 11, absorbing the vibration and impact generated during the drilling process 400, reducing the impact on the angle detection unit 21, and thus improving the accuracy of the detection. The presence of the elastic element 22 allows the angle detection unit 21 to have a certain displacement during the detection process, enabling the angle detection unit 21 to better adapt to the dynamic changes of the drilling equipment 400.

[0040] In some embodiments, the angle detection assembly 2 further includes an anti-slip pad 23, which is connected to the angle detection unit 21 and is located on the side of the angle detection unit 21 away from the elastic member 22. It is understood that, as... Figures 1-3 As shown, the anti-slip pad 23 is located on the side of the angle detection unit 21 adjacent to the drilling 400 equipment. When the angle detection unit 21 comes into contact with the drilling 400 equipment, the anti-slip pad 23 can play a buffering and anti-slip role, reducing the risk of the angle detection unit 21 being damaged.

[0041] Preferably, the side of the anti-slip mat 23 furthest from the angle detection unit 21 is a convex arc surface. It is understood that, as... Figures 1-3 As shown, the anti-slip pad 23 can be made of soft rubber material, which can effectively prevent the angle detection unit 21 from sliding, thereby improving the stability and accuracy of the detection. The wear resistance of the anti-slip pad 23 helps protect the angle detection unit 21 and extend its service life.

[0042] In some embodiments, the support assembly 1 further includes a buffer pad 12, in a plane orthogonal to the extension direction of the support body 11, the projected outline of the support body 11 is annular, and the buffer pad 12 is adapted to and connected to the inner peripheral wall of the support body 11.

[0043] Specifically, such as Figures 1-3 As shown, the support body 11 is annular, and the central hole area of ​​the support body 11 forms the borehole detection area 10. The angle detection component 2 is installed on the inner peripheral wall of the support body 11. The buffer pad 12 is adapted to the inner peripheral wall of the support body 11 so that it can be connected to the inner peripheral wall of the support body 11 by adhesive, bolts or other fasteners to ensure close contact during the drilling process 400.

[0044] Understandably, the presence of the buffer pad 12 can reduce the vibration of the support assembly 1 during drilling 400, thereby improving its stability. The buffer pad 12 can effectively protect the support body 11 and the angle detection unit 21, extending their service life. The buffering effect of the buffer pad 12 helps reduce safety risks during construction.

[0045] In some embodiments, the radial dimension of the inner peripheral wall of the buffer pad 12 is less than or equal to the radial dimension of the fracturing drilling equipment 300.

[0046] Understandably, the radial dimension of the inner peripheral wall of the buffer pad 12 is designed to be less than or equal to the radial dimension of the fracturing drilling equipment 300, and the inner peripheral wall of the buffer pad 12 is in compressive contact with the outer peripheral wall of the drilling equipment 400. This allows the buffer pad 12 to adapt to different models and sizes of drilling equipment 400, improving the versatility of the support device. The presence of the buffer pad 12 can reduce the direct impact of the drilling equipment 400 on the support body 11, protecting the support body 11 from damage.

[0047] In some embodiments, the inner peripheral wall of the support body 11 is provided with a plurality of mounting slots 13, and the plurality of mounting slots 13 correspond one-to-one with a plurality of angle detection components 2, with a portion of the angle detection components 2 placed in the mounting slots 13.

[0048] It is understandable that, such as Figures 1-3 As shown, the mounting slot 13 is used to fix the angle detection components 2, ensuring that they maintain the correct position and orientation during the drilling process 400. The mounting slot 13 can help the angle detection components 2 be correctly positioned on the support body 11, and can also guide the movement of the angle detection components 2 to a certain extent, improving their detection accuracy.

[0049] In some embodiments, the angle detection component 2 further includes a warning element (not shown in the figure), which is electrically connected to the angle detection unit 21. When the pressure value applied to the angle detection unit 21 exceeds a preset value, the warning element is used to issue a warning signal.

[0050] Understandably, the main function of the warning device is to issue a warning signal when the angle detection unit 21 detects a pressure value exceeding a preset value, reminding the operator to pay attention to the deviation of the drilling equipment 400 and potential safety risks. By monitoring the pressure value in real time, the warning device can help prevent damage to the angle detection unit 21 due to excessive pressure. The warning signal can also serve as a reminder for equipment maintenance, informing the operator to perform timely inspections and maintenance.

[0051] In other words, the warning system can issue an alert when the pressure exceeds the safe range, promptly reminding operators to make necessary adjustments, thereby improving construction safety. The warning system can prevent damage to the angle detection unit 21 due to excessive pressure, extending the equipment's service life. Operators can use the warning system to stay informed about the equipment's status, reducing construction delays caused by unexpected downtime or malfunctions.
