[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0035] The technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] Example 1

[0037] See also Figure 1-5 As shown, a device for controlling combined disasters of rock burst and gas in coal mines and a method for using the device include a protective device 1, which is composed of a plurality of connected components.

[0038] Among them, the protective device is mainly composed of multiple components. The component structure is convenient for transportation and maintenance, and is easy to disassemble after use, making it more flexible to use.

[0039] Multiple components include a middle ring body 2, a connecting plate 3, an expansion plate 4 and a blasting protection bag 15. One side of the middle ring body 2 is fixedly connected with multiple connecting plates 3, and the other side of the expansion plate 4 is fixedly connected with multiple expansion plates 4 matching the connecting plate 3. The blasting protection bag 15 is installed between two adjacent connecting plates 3. The blasting protection bag 15 is a "T"-shaped structure. The blasting protection bag 15 completely covers the area between the two adjacent connecting plates 3 and the two adjacent expansion plates 4. A sensor 14 for monitoring blasting impact is fixedly installed in the middle of the blasting protection bag 15. The sensor 14 is a distance sensor or a vibration sensor. The distance sensor can monitor the impact amplitude of the blasting protection bag 15.

[0040] Among them, the sensor 14 is stably supported between the two connecting plates 3 by the blasting protection bag 15. When strong impact and vibration occur in the coal mine tunnel, the impact amplitude is monitored by the sensor 14, and an alarm is issued through the external monitoring equipment to alert the people in the tunnel.

[0041] The mutual distances between the multiple components are adjusted by the cooperation of the connecting plate 3 and the expansion plate 4, so that the protective device 1 can be quickly expanded and installed.

[0042] An expansion slot 5 is provided in the middle of the outer side of the connecting plate 3, and snap-in slots 6 are symmetrically provided on both sides of the expansion slot 5. A plurality of snap-in strips 7 are fixedly connected inside the snap-in slot 6, and a limiting slide 8 is symmetrically fixedly connected to the outer side of the expansion slot 5. A curved notch 27 is provided on the outer side of the limiting slide 8; a reinforcement plate 9 matching the expansion slot 5 is fixedly connected to the middle of the inner surface of the expansion plate 4, and snap-in blocks 10 matching the snap-in slot 6 are symmetrically fixedly connected on both sides of the end of the reinforcement plate 9 away from the central ring body 2, and limiting sliders 11 corresponding to the limiting slide 8 are symmetrically fixedly connected on both sides of the bottom of the end of the expansion plate 4 away from the central ring body 2.

[0043] In this embodiment, further, the connecting plate 3 and the expansion plate 4 are stretched and adjusted through the cooperation of the expansion slot 5 and the reinforcement plate 9. The cooperation of the snap-in strip 7 and the snap-in block 10 can make the expansion plate 4 more stable at one end position after it moves to the position. At the same time, it can also provide gentle support on both sides of the expansion plate 4 when responding to impact. When the two components are installed, the curved notch 27 can facilitate the limiting slider 11 to enter the limiting slot 8. The limiting slot 8 can prevent the expansion plate 4 from easily falling out of the limiting slot 8 when it is stretched toward the end away from the connecting plate 3. When multiple components are expanded, the protective device 1 can be quickly stretched and unfolded, and at the same time, the components can be prevented from detaching from each other.

[0044] A fixing hole A12 is provided in the middle of the expansion plate 4 and extends through the expansion slot 5. A fixing hole B13 is provided inside the expansion slot 5 to match the fixing hole A12.

[0045] In this embodiment, further, after the multiple components are stretched and expanded, the expansion plate 4 and the connecting plate 3 can be stably connected by bolts passing through the fixing holes A12 and the fixing holes B13 in sequence, thereby making the protective device 1 more stable as a whole.

[0046] Two sets of clamping mechanisms are fixedly connected to the blasting protection bag 15 in the circumferential direction, and the clamping mechanisms include springs 16 and hooks 17. The middle ring body 2 is fixedly connected to the circumference with the same number of hanging ring groups A18 as the connecting plate 3, and the middle part of the outer side of the expansion plate 4 is fixedly connected to the hanging ring group B26.

[0047] In this embodiment, the explosion protection bag 15 is further installed between the two connecting plates 3 through the cooperation of the hook 17 and the hanging ring group A18 and the hanging ring group B26. The spring 16 can support the explosion protection bag 15 to be flatter, so that the position of the sensor 14 remains fixed.

[0048] In this embodiment, further, the structures of multiple components are the same, which facilitates the production, processing and combination of multiple components.

[0049] Furthermore, the clamping strip 7 is made of mild steel and has a semi-annular structure. The clamping strip 7 can produce deformation properties, so that the positions of the expansion plate 4 and the reinforcement plate 9 can be kept more stable after the expansion plate 4 and the reinforcement plate 9 are pulled back and forth, thereby facilitating the bolts to pass through the fixing holes A12 and the fixing holes B13 for installation and fixation.

[0050] Furthermore, the plurality of clamping strips 7 are distributed at equal intervals, and a clamping groove is formed between two adjacent clamping strips 7 , and the clamping block 10 is limited by the clamping groove.

[0051] Furthermore, the two clamping blocks 10 are respectively located in the middle of the two clamping slots 6 , which can facilitate the horizontal sliding of the expansion board 4 and reduce the sliding adjustment resistance of the expansion board 4 .

[0052] Example 2

[0053] See also Figure 6 As shown, a device for controlling combined disasters of rock burst and gas in coal mines is provided. A safety net tube 19 is provided on the inner side of the connecting plate 3. A plurality of buffer springs 20 are fixedly connected to the circumference of the safety net tube 19. A buffer plate 21 is fixedly connected to the outer side of the buffer spring 20. A connecting assembly is also fixedly connected to the outer side of the safety net tube 19. The safety net tube 19 is fixedly connected to the inner walls of the plurality of connecting plates 3 through the connecting assembly.

[0054] In this embodiment, the provision of the safety net tube 19 can provide further safety protection for the personnel in the tunnel, preventing a huge impact in the tunnel from damaging the connecting plate 3 and the expansion plate 4, and further causing an impact on the inside of the connecting plate 3 and the expansion plate 4, thereby greatly reducing the safety hazards caused to the personnel in the tunnel. At the same time, the impact pressure is buffered by the buffer spring 20 and the buffer plate 21 outside the safety net tube 19, further improving the safety protection effect.

[0055] The connecting assembly includes a mounting plate 22 and a mounting opening 23 opened on the inner side of the connecting plate 3. One end of the mounting plate 22 is fixedly connected to a limiting card plate 25 that matches the mounting opening 23. One side of the mounting opening 23 is provided with a limiting slide 24 that matches the mounting plate 22. The inner sides of the mounting opening 23 and the limiting slide 24 are provided with a limiting groove 28 that is interference fit with the limiting card plate 25; multiple safety net cylinders 19 are connected and fixed to each other.

[0056] In this embodiment, further, the safety net tube 19 is inserted and rotated for installation through the cooperation of the mounting plate 22 and the mounting port 23, and the limiting groove 28 is interference fit with the limiting clamping plate 25, which can make the safety net tube 19 more stable after installation through the connecting plate 3. The multiple safety net tubes 19 are connected to each other, so that there is no gap between the safety net tubes 19, which makes it easier to avoid the disaster site in the safety net tube 19.

[0057] A method for using a device for controlling combined disasters of rock burst and gas in coal mines, comprising the following steps:

[0058] S1: Assembly: First, according to the length of the tunnel to be protected and managed, multiple middle ring bodies 2 are connected through the cooperation of the connecting plate 3 and the expansion plate 4. The multiple middle ring bodies 2 are connected by the cooperation of the clamping blocks 10 on both sides of the reinforcing plate 9 and the clamping groove 6. One end of the reinforcing plate 9 is moved toward the bottom of the expansion groove 5 to assemble multiple contraction sections of the middle ring body 2;

[0059] S2: After transportation and assembly, the assembled contraction section of the middle ring body 2 is moved to the site where it is needed by means of transportation equipment, and then multiple middle ring bodies 2 with multiple contraction sections are assembled and connected into a whole in the same way;

[0060] S3: Extension debugging: One end of the protective device 1 is located outside the lane, and the other end of the pulling protective device 1 is extended into the lane. During the pulling process, the reinforcing plate 9 increases the distance between the two middle ring bodies 2 through the expansion slot 5. The limiting slide 8 prevents the connecting plate 3 and the expansion plate 4 from separating from each other during the pulling process, thereby covering the lane;

[0061] S4: Protection detection installation. After the tunnel is covered, the blasting protection bag 15 is aligned with the two connecting plates 3, and then the hooks 17 on the circumference of the blasting protection bag 15 are interlocked with the hanging ring group A18 and the hanging ring group B26 to install the blasting protection bag 15. At the same time, the position of the sensor 14 is fixed, and the distance between multiple sensors 14 and the tunnel wall is recorded by the program. When strong vibrations, instantaneous reactions and explosion shocks occur in the tunnel, the blasting protection bag 15 can buffer the shock. At the same time, the impact position of the regional sensor 14 is monitored by using a monitoring program in conjunction with multiple sensors 14, and an alarm is triggered according to the impact amplitude to achieve protection monitoring of the area.

[0062] To sum up, when in use, first install multiple components on each other. During installation, align the connecting plate 3 and the expansion plate 4 of a single component so that the reinforcement plate 9 and the expansion slot 5 correspond. By squeezing the reinforcement plate 9 and the expansion slot 5 inward, the connecting plate 3 and the expansion plate 4 are docked with each other. At the same time, the limiting slider 11 slides into the limiting slide groove 8 through the curved notch 27. In this way, the connection between the middle ring bodies 2 is completed, and the protective device 1 is formed by connecting multiple middle ring bodies 2.

[0063] Next, one end of the protective device 1 is pulled and moved into the tunnel, and the other end of the protective device 1 is located outside the tunnel. During the pulling process, the limit slider 11 slides in the limit slide groove 8, and the clamping block 10 slides through the clamping groove 6. When the limit slider 11 slides to one end of the limit slide groove 8, it no longer continues to slide, thereby expanding the space between multiple components to meet the use length of the tunnel.

[0064] Then the blasting protection bag 15 is installed between two adjacent connecting plates 3 through the cooperation of the hook 17 and the hanging ring group A18 and the hanging ring group B26. When the hook 17 is connected with the hanging ring group A18 and the hanging ring group B26, the blasting protection bag 15 is supported more flatly, making the distance between the sensor 14 and the tunnel wall more stable.

[0065] Then, when a strong impact or vibration occurs in the tunnel, the sensor 14 senses it and transmits the signal to the external program control terminal, and then activates the alarm signal, so that personnel can quickly move to an area away from the vibration signal to avoid disasters and ensure their personal safety.
