Technical Field

[0001] This application relates to the field of rockburst prevention and control, specifically to a monitoring and early warning device and method for rockburst disaster prevention and control in coal mines. Background Technology

[0002] Coal mine rockburst refers to a destructive geological hazard that occurs during coal mining when uneven stress on the coal seam roof leads to its collapse, causing drastic changes in mine pressure. To prevent and control rockburst accidents, it is necessary to implement rockburst detection and early warning systems in coal mines, thus requiring a coal mine rockburst disaster prevention and monitoring early warning device.

[0003] Chinese invention patent application number CN201910199363.5 discloses a coal mine rockburst monitoring and early warning device. Although this coal mine rockburst monitoring and early warning device solves the problem in the prior art that the reusable stress gauge cannot fully fit with the borehole wall, resulting in low monitoring accuracy and inability to conduct continuous monitoring, it still has disadvantages in use. It does not have an automatic movement function, and when the hole is deep, the device is prone to collision with the inner wall of the hole during installation, resulting in inconvenient installation. In addition, the structure and function are limited, making it difficult to control the installation depth of the device, resulting in poor performance during use.

[0004] Therefore, it is necessary to propose a monitoring and early warning device and method for preventing and controlling coal mine rockburst disasters to solve the above problems. Summary of the Invention

[0008] Optionally, the inner side of the detection box is provided with a plurality of sliding grooves symmetrically distributed in a ring array. The inner side of each sliding groove is movably connected with a threaded ramp block. Adjacent two symmetrically distributed threaded ramp blocks are connected by a second threaded rod through and threaded together.

[0009] Optionally, a third motor is fixedly installed at one end of the inner side of the detection box, and a third spur gear is fixedly connected to one end of the output shaft of the third motor. A toothed ring is movably connected to the inner side of the detection box. The toothed ring is a double-toothed ring with teeth on both the inner and outer sides.

[0012] A method for early warning of a coal mine rockburst disaster prevention and monitoring device includes the following steps: A: Drilling preparation: First, a special drill frame and drill rod guide device are required to ensure the accuracy of the drilling diameter and direction. At the same time, a suitable drilling location should be selected, which is generally located in the middle of the mining area, parallel to the bedding plane and perpendicular to the coal wall.

[0014] (III) Beneficial Effects This invention provides a monitoring and early warning device and method for preventing and controlling rockburst disasters in coal mines, which has the following beneficial effects: 1. This invention uses a first spur gear that is adapted to a tooth groove, thereby driving a fourth helical gear to rotate via a second motor. The fourth helical gear is adapted to multiple third helical gears, thereby driving multiple first threaded rods to rotate. This allows the rotating rod to rise and fall after being adapted to a threaded movable block. Multiple curved spring plates allow the rotating rod to connect to the threaded drive tube, thus allowing the threaded drive tube to fit more tightly against the wall of the mounting hole. The first motor can drive a second helical gear to rotate. The second helical gear is adapted to multiple second helical gears, and the second helical gears are adapted to a limiting movable hole, thereby driving the threaded drive tube to rotate without hindering its rise and fall, thus enabling the device to move.

[0015] 2. This invention uses a third motor to drive a third spur gear to rotate. Through a gear ring and multiple second spur gears, multiple second threaded rods can be driven to rotate. This allows control of two threaded ramp blocks to move closer or further apart. When the two threaded ramp blocks move closer together, they can push the lifting block outward, thereby inflating the airbag tube. Simultaneously, in conjunction with an air pump and air pipe, air can be injected into the inside of the airbag tube, causing the pressure detector on its surface to fit tightly against the inner wall of the mounting hole, thus enabling the monitoring of impact ground pressure.

[0016] 3. This invention can send data from multiple pressure detectors via a signal transmitter, which facilitates simultaneous monitoring of multiple detection points from the backend. The pull ring makes the device easier to hold during installation and more convenient to use. Attached Figure Description

A third helical gear 17 is fixedly connected to the other end of each of the multiple first threaded rods 16. A second helical gear 17 is fixedly installed inside the power box 1. The output end of the second motor 18 is fixedly connected to the first spur gear 19. The inside of the power box 1 is rotatably connected to the fourth helical gear 20. The fourth helical gear 20 is also adapted to multiple third helical gears 17.

The outer surface of the threaded drive tube 6 is provided with a thread with a triangular cross-section and is made of metal steel.

[0021] In this embodiment, the first spur gear 19 is adapted to the tooth groove 21, thereby driving the fourth helical gear 20 to rotate via the second motor 18. The fourth helical gear 20 is adapted to multiple third helical gears 17, thereby driving multiple first threaded rods 16 to rotate. This allows the rotating rod 4 to rise and fall after being adapted to the threaded movable block 15.

Example

[0022] As an optional technical solution of the present invention: the inner side of the detection box 2 is provided with a plurality of sliding grooves 22 symmetrically distributed in a ring array, and the inner side of each sliding groove 22 is movably connected with a threaded ramp block 23. Two adjacent threaded ramp blocks 23 symmetrically distributed are connected by a second threaded rod 24 through and threadedly connected. There are multiple second threaded rods 24, and each of the multiple second threaded rods 24 is a double threaded screw. One end of each of the multiple second threaded rods 24 is fixedly connected with a second spur gear 25.

[0023] As an optional technical solution of the present invention: a third motor 26 is fixedly installed on one end of the inner side of the detection box 2, and a third spur gear 27 is fixedly connected to one end of the output shaft of the third motor 26. A toothed ring 28 is movably connected to the inner side of the detection box 2. The toothed ring 28 is a double toothed ring with teeth on both the inner and outer sides. A plurality of lifting blocks 29 arranged in a ring array are movably connected to the inner side of the detection box 2. The plurality of lifting blocks 29 are respectively adapted to a plurality of symmetrically distributed threaded ramp blocks 23.

[0024] As an optional technical solution of the present invention: an airbag tube 30 is movably connected to the outer circle of multiple lifting blocks 29. The airbag tube 30 is made of rubber material, and multiple pressure detectors 33 are fixedly installed on the outer circle surface of the airbag tube 30 in a ring array with equal spacing.

[0025] In this embodiment, the third motor 26 drives the third spur gear 27 to rotate. The gear ring 28 is adapted to multiple second spur gears 25, thereby driving multiple second threaded rods 24 to rotate. This allows control of the two threaded ramp blocks 23 to move closer or further apart. When the two threaded ramp blocks 23 move closer together, they can push the lifting block 29 outward, thereby inflating the airbag tube 30. At the same time, the air pump 31 and air pipe 32 can inject air into the inside of the airbag tube 30, so that the pressure detector 33 on its surface fits tightly against the inner wall of the mounting hole, thereby enabling the monitoring of impact ground pressure. Example

[0026] As an optional technical solution of the present invention: a signal transmitter 34 is fixedly connected to one end of the power box 1 on one side, the signal transmitter 34 is adapted to multiple pressure detectors 33, and a pull ring 35 is movably connected to one end of the power box 1.

[0027] In this embodiment, the signal transmitter 34 can send the detection data of multiple pressure detectors 33, which makes it easier for the background to control the situation of multiple detection points at the same time. The pull ring 35 makes the device easier to hold during installation and more convenient to use.

[0028] A method for early warning of a coal mine rockburst disaster prevention and monitoring device includes the following steps: A: Drilling preparation: First, a special drill frame and drill rod guide device are required to ensure the accuracy of the drilling diameter and direction. At the same time, a suitable drilling location should be selected, which is generally located in the middle of the mining area, parallel to the bedding plane and perpendicular to the coal wall. B: Drilling operation: Drilling should be carried out within 3.5 times the mining height at the detection depth where the maximum impact risk is determined. If an impact risk is determined to exist within this range, the detection can be stopped. C: Install stress sensors: Install monitoring devices inside the drilled boreholes. These monitoring devices should be able to cover all stages of the coal seam deformation process. D: Data Acquisition: As the working face advances, data from stress sensors is continuously collected, including parameters such as changes in internal stress of the coal body; E: Data Analysis: Collect and record data such as borehole depth, time, and dynamic effects at that time, and then analyze this data to assess the degree of danger of rockburst; F: Early warning and prevention: Based on the detection results, take corresponding anti-rock pressure measures. For example, when it is detected that there is a risk of rockburst in the drilled area, water can be injected to relieve pressure. The pressure relief area is the coal body 0-150m in front of the coal face, and it moves with the advancement of the working face.

[0029] As an optional technical solution of the present invention: the diameter of the hole drilled by the drilling equipment is adapted to the diameter of the monitoring device.

[0030] In summary: When using the device, first select the location of the mounting hole, and then use a special drill frame and drill rod guide device to drill a hole in the inner wall of the coal mine. Then, use the hand-held pull ring 35 to place the device into the mounting hole. The second motor 18 drives the first spur gear 19 to rotate. The first spur gear 19 is adapted to the tooth groove 21, thus driving the fourth helical gear 20 to rotate via the second motor 18. The fourth helical gear 20 can simultaneously drive multiple third helical gears 17 to rotate, thereby driving multiple first threaded rods 16 to rotate. This allows the device to rotate in conjunction with the threaded movable block 15. After being connected, the rotating rod 4 is raised and lowered. Multiple curved spring plates 5 connect the rotating rod 4 to the threaded drive tube 6, allowing the threaded drive tube 6 to fit more tightly against the wall of the mounting hole. The first motor 13 drives the second helical gear 14 to rotate. The second helical gear 14 is adapted to multiple second helical gears 12, which in turn are adapted to the limiting movable hole 11. This allows the threaded drive tube 6 to rotate without hindering its raising and lowering, thus enabling the device to move. When the threaded drive tube 6 is not rotating, it can self-lock, preventing the device from... Displaced by gravity, the third motor 26 drives the third spur gear 27 to rotate. Through the gear ring 28, it meshes with multiple second spur gears 25, thereby driving multiple second threaded rods 24 to rotate. This controls the two threaded ramp blocks 23 to move closer or further apart. When the two threaded ramp blocks 23 move closer together, they push the lifting block 29 outwards, inflating the airbag tube 30. Simultaneously, the air pump 31 and air pipe 32 inject air into the inside of the airbag tube 30, causing the pressure detector 33 on its surface to fit tightly against the inner wall of the mounting hole. This allows for the detection of impact ground pressure. Monitoring is conducted by transmitting data from multiple pressure detectors 33 via signal transmitter 34, allowing the backend to simultaneously monitor the status of multiple detection points. The pull ring 35 makes the device easier to hold during installation and more convenient to use. As the working face advances, data from stress sensors is continuously collected, including parameters such as changes in internal stress of the coal body. Data such as borehole depth, time, and dynamic effects are collected and recorded. These data are then analyzed to assess the degree of rockburst risk, and corresponding anti-rockburst measures are taken based on the detection results.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
