Description

A device and method for monitoring slope stability in tailings dams Technical Field

[0001] This invention relates to the field of slope stability monitoring technology, specifically to a slope stability monitoring device and method for tailings ponds. Background Technology

[0002] A tailings dam is a large, man-made reservoir or landfill specifically designed to store tailings. After the mined ore is crushed, ground, and then valuable concentrates (such as copper or iron concentrate) are extracted using physical or chemical methods (e.g., flotation or magnetic separation), the remaining muddy, sandy waste containing a large amount of water is called tailings. The construction of tailings dam slopes utilizes a combination of natural earth and rock, synthetic materials, and specialized reinforcement materials, with the core objective of ensuring structural stability and effective seepage prevention. As a major hazard source, the slope stability of tailings dams directly affects the safety of life and property downstream and the environment.

[0003] In the prior art, patent application number CN202510287577.3 discloses a mine slope stability monitoring device, which relates to the field of mine slope stability monitoring technology. This mine slope stability monitoring device includes a monitoring component and a mine slope. The monitoring component is installed at the top of the mine slope, and multiple monitoring components are installed on the slope. Each monitoring component includes a rotating base and a fixed part, with the rotating base located at the front end of the fixed part. The upper surface of the rotating base has a vertical slot that extends vertically through the rotating base. A vertical detection rope is inserted into the interior of the vertical slot. Both sides of the rotating base have horizontal slots, with two horizontal slots corresponding to each rotating base surface. This solution solves the problems of existing mine slope stability monitoring methods, such as the use of numerous electric devices, complex installation, the need for extensive power supply, susceptibility to malfunction and damage, high cost, complex operation, damage to the slope, and inaccurate monitoring data.

[0004] However, when this mine slope stability monitoring device is applied to the slope stability monitoring of tailings dams, it requires staff to pay close attention to the camera footage at all times. Furthermore, one camera covers multiple monitoring components, making it difficult for staff to detect abnormalities in the monitoring components in a timely manner and resulting in a huge waste of manpower. Summary of the Invention

[0007] Preferably, a resistance plate insertion hole is provided on the monitoring component mounting platform. The resistance plate has a rectangular plate structure and is movably inserted into the resistance plate insertion hole, and both ends of the resistance plate extend out of the resistance plate insertion hole. Pull ropes are fixed at both ends of the resistance plate extending out of the resistance plate insertion hole.

[0008] Preferably, a conductive rod installation hole is provided on the monitoring component mounting platform. The conductive rod installation hole has a circular hole structure and is penetrated with the resistance plate insertion hole. One end of the conductive rod is movably inserted into the conductive rod installation hole, and a plugging sleeve is movably inserted into the other end of the conductive rod installation hole. The plugging sleeve has a "T"-shaped circular cylindrical structure, and the negative wire is movably inserted into the inner ring of the plugging sleeve.

[0009] Preferably, a spring is movably inserted into the conductive rod installation hole. One end of the spring abuts against the conductive rod, and the other end of the spring abuts against the plugging sleeve.

[0010] Preferably, a first screw groove is provided on the monitoring component mounting platform. A first screw is rotatably connected to the plugging sleeve. External threads are provided on the first screw, and internal threads are provided in the first screw groove. The internal threads of the first screw groove are matched with the external threads of the first screw.

[0011] Preferably, damping sleeves are sleeved on both ends of the resistance plate extending out of the resistance plate insertion hole. The damping sleeves have a "return" - shaped plate structure, and an interference fit is adopted between the inner ring of the damping sleeve and the resistance plate.

[0012] Preferably, an audible and visual alarm is fixed at the top of the remote warning module, and the remote warning module is electrically connected to the audible and visual alarm. One end of a power supply line is electrically connected to the remote warning module, and the other end of the power supply line is electrically connected to the resistance detection device with the built-in power source.

[0013] Preferably, the base is a cylindrical structure, and a retaining ring is fixedly fitted on the base. The retaining ring is a circular plate structure. A second screw groove is provided on the frame, and a second screw is rotatably connected to the rotating seat. An internal thread is provided in the second screw groove, and an external thread is provided on the second screw. The external thread of the second screw mates with the internal thread of the second screw groove.

[0014] Preferably, the retaining ring is provided with an anti-slip groove, and an anti-slip ring is fixed in the anti-slip groove. The anti-slip ring has a circular annular plate structure, and the outer ring of the anti-slip ring abuts against the rotating seat.

[0015] A method for monitoring the slope stability of a tailings dam includes a slope stability monitoring device for the tailings dam and the following steps: Step 1: Installation of the rotating base: During the construction of the tailings dam slope, multiple sets of base grooves are evenly reserved. After the rotating base is fitted onto the base, the base is placed in the base groove. The outer surface of the tailings dam slope is formed by the drying of cement and other reinforcing materials. When the cement dries, the base is solidified in the base groove. The rotating base cannot detach from the base due to the obstruction of the retaining ring and can only rotate around the base, thus realizing the installation of the rotating base; Step 2: Installation of the monitoring component mounting platform: Install the monitoring component... The mounting platform fixed at the lower end is inserted into the rotating base, and the second screw groove on the platform is aligned with the second screw on the rotating base. Then, the second screw is tightened into the second screw groove under the action of the threaded connection. The monitoring component mounting platform can then be installed onto the rotating base. After that, the pull rope between the two adjacent sets of resistor plates is tightened and knotted. Step 3: Automatic monitoring: Under normal conditions, the remote alarm module, positive wire, resistor plate, conductive rod and negative wire form a complete circuit. The damping sleeve on the resistor plate will dampen the resistor plate when the distance of the resistor plate extending from the resistor plate insertion hole changes. The length of the resistor plate connected to the circuit significantly affects the resistance value in the circuit. The self-powered resistance detection device can measure the resistance value in the circuit. When the resistance value does not change significantly, the self-powered resistance detection device will not supply power to the remote alarm module. When a landslide or tilt occurs at a certain point on the tailings dam slope, the distance between the monitoring component mounting platform at that point and the monitoring component mounting platforms at points where no landslide or tilt has occurred increases. This causes the resistor plates on that group of monitoring component mounting platforms to pull against the resistor plates on adjacent groups of monitoring component mounting platforms. This pulling force is much greater than the force exerted by the damping sleeve on the resistor plates. Damping causes a change in the distance the resistor plate extends beyond its insertion hole, which in turn changes the length of the resistor plate connected to the circuit. This results in a significant change in the resistance value within the circuit. When the self-powered resistance detection device detects this significant change in resistance, it powers the remote alarm module via the power supply line. Once powered on, the remote alarm module sends an alarm to the remote monitoring terminal connected to it wirelessly. Simultaneously, the remote alarm module powers the audible and visual alarm, causing it to emit audible and visual signals. By simultaneously using these signals, on-site alarms are triggered, thereby achieving real-time automatic monitoring of the stability of the tailings dam slope.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The slope stability monitoring device and method for tailings dams proposed in this invention, when a landslide or tilt occurs at a certain part of the tailings dam slope, increases the distance between the monitoring component mounting platform at that location and the monitoring component mounting platforms at locations where no landslide or tilt has occurred. This causes the resistance plates on that set of monitoring component mounting platforms to pull against each other, and this pulling force is much greater than the damping force of the damping sleeve on the resistance plates. Consequently, the distance by which the resistance plates extend beyond the resistance plate insertion holes changes, and also affects the electrical... The change in the length of the circuit connected to the baffle plate causes a significant change in the resistance value in the circuit. After the self-powered resistance detection device detects the significant change in resistance value, it powers the remote alarm module through the power supply line. Once powered on, the remote alarm module sends an alarm to the remote monitoring terminal connected to it via a wireless signal. At the same time, the remote alarm module powers the audible and visual alarm, causing it to emit audible and visual signals. The simultaneous use of these signals to issue a field alarm enables real-time automatic monitoring of the stability of the tailings dam slope, saving manpower and shortening the alarm response time.

They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1 to 6. This invention provides a technical solution: a slope stability monitoring device for tailings ponds, comprising: a tailings pond slope 1, a base groove 2 formed on the tailings pond slope 1, a base 3 fixed in the base groove 2, a rotating seat 5 rotatably connected to the base 3, a frame 6 movably connected to the rotating seat 5, a monitoring component mounting platform 7 fixed on the frame 6, a resistance plate 9 movably inserted into the monitoring component mounting platform 7, one end of the resistance plate 9 electrically connected to a positive electrode wire 10, a conductive rod 12 movably inserted into the monitoring component mounting platform 7, one end of the conductive rod 12 abutting against the resistance plate 9, the other end of the conductive rod 12 electrically connected to a negative electrode wire 11, and a resistance detection device 13 with its own power supply fixed at the top of the monitoring component mounting platform 7. The remote alarm module 14 has its positive wire 10, the end away from the resistor plate 9, and its negative wire 11, the end away from the conductive rod 12, both electrically connected to the resistance detection device 13 with its own power supply. The monitoring component mounting platform 7 has a resistor plate insertion hole 8. The resistor plate 9 has a rectangular plate structure and is movably inserted into the resistor plate insertion hole 8. Both ends of the resistor plate 9 extend out of the resistor plate insertion hole 8, and pull ropes 26 are fixed to both ends of the resistor plate 9 extending out of the resistor plate insertion hole 8. An audible and visual alarm 15 is fixed to the top of the remote alarm module 14, and the remote alarm module 14 is electrically connected to the audible and visual alarm 15. One end of a power supply line 16 is electrically connected to the remote alarm module 14, and the other end of the power supply line 16 is electrically connected to the resistance detection device 13 with its own power supply.

[0021] During the construction of the tailings dam slope 1, multiple sets of base grooves 2 are evenly reserved. After the rotating seat 5 is fitted onto the base 3, the base 3 is placed in the base groove 2. The outer surface of the tailings dam slope 1 is formed by the drying of cement and other reinforcing materials. When the cement dries, the base 3 is solidified in the base groove 2. The rotating seat 5 cannot detach from the base 3 due to the obstruction of the retaining ring 4 and can only rotate around the base 3, thus realizing the layout of the rotating seat 5. The monitoring component mounting platform 7 is installed on the rotating seat 5, and then two adjacent sets are... The pull ropes 26 between the resistor plates 9 are taut and knotted; under normal conditions, the remote alarm module 14, the positive wire 10, the resistor plates 9, the conductive rod 12, and the negative wire 11 form a complete circuit. The length of the resistor plate 9 connected to the circuit will have a significant impact on the resistance value in the circuit. The self-powered resistance detection device 13 can measure the resistance value in the circuit. When the resistance value does not change significantly, the self-powered resistance detection device 13 will not supply power to the remote alarm module 14. When a certain tailings dam slope 1... When a landslide or tilt occurs at a location, the distance between the monitoring component mounting platform 7 at that location and the monitoring component mounting platform 7 at locations where no landslide or tilt has occurred increases. This causes the resistance plate 9 on that set of monitoring component mounting platforms 7 to pull against the resistance plates 9 on adjacent sets of monitoring component mounting platforms 7. This pulling force is much greater than the damping force of the damping sleeve 21 on the resistance plate 9, which in turn changes the distance the resistance plate 9 extends out of the resistance plate insertion hole 8 and also changes the length of the resistance plate 9 connected to the circuit. This causes a significant change in the resistance value in the circuit. After the resistance detection device 13 with its own power supply measures the significant change in resistance value, it supplies power to the remote alarm module 14 through the power supply line 16. After the remote alarm module 14 is powered on, it sends an alarm to the remote monitoring terminal connected to the remote alarm module 14 via a wireless signal. At the same time, the remote alarm module 14 supplies power to the audible and visual alarm 15, causing the audible and visual alarm 15 to emit audible and visual signals. The audible and visual signals are used to provide on-site alarms simultaneously, thereby realizing real-time automatic monitoring of the stability of the tailings dam slope 1.

[0022] Example 2: Based on Example 1, in order to realize the installation between the monitoring component mounting platform 7 and the rotating seat 5, the base 3 is a cylindrical structure, and a retaining ring 4 is fixed on the base 3. The retaining ring 4 is a circular plate structure. The platform 6 is provided with a second screw groove 22, and a second screw 23 is rotatably connected to the rotating seat 5. The second screw groove 22 is provided with an internal thread, and the second screw 23 is provided with an external thread. The external thread of the second screw 23 is engaged with the internal thread of the second screw groove 22.

[0023] Insert the frame 6, which is fixed at the lower end of the monitoring component mounting platform 7, into the rotating base 5, and align the second screw groove 22 on the frame 6 with the second screw 23 on the rotating base 5. Then, screw the second screw 23 so that the second screw 23 is tightened in the second screw groove 22 under the action of the threaded connection, and the monitoring component mounting platform 7 can be installed on the rotating base 5.

[0024] Embodiment 3: On the basis of Embodiment 2, in order to ensure that the conductive rod 12 is always in contact with the resistor plate 9, a conductive rod mounting hole 27 is provided on the monitoring component mounting table 7. The conductive rod mounting hole 27 has a circular hole structure. The conductive rod mounting hole 27 is penetrated with the resistor plate insertion hole 8. The conductive rod 12 is movably inserted into one end of the conductive rod mounting hole 27. A plugging sleeve 17 is movably inserted into the other end of the conductive rod mounting hole 27. The plugging sleeve 17 has a "T"-shaped circular cylindrical structure. The negative electrode wire 11 is movably inserted into the inner ring of the plugging sleeve 17. A spring 18 is movably inserted into the conductive rod mounting hole 27. One end of the spring 18 abuts against the conductive rod 12, and the other end of the spring 18 abuts against the plugging sleeve 17. A first thread groove 19 is provided on the monitoring component mounting table 7. A first screw 20 is rotatably connected to the plugging sleeve 17. The first screw 20 has an external thread, and the first thread groove 19 has an internal thread. The internal thread of the first thread groove 19 is matched with the external thread of the first screw 20.

[0025] The plugging sleeve 17 is installed in the conductive rod mounting hole 27. One end of the spring 18 abuts against the plugging sleeve 17 and the other end abuts against the conductive rod 12. The spring 18 is in a compressed state, so that the spring 18 always generates a thrust on the conductive rod 12, making the conductive rod 12 always pressed tightly on the resistor plate 9. When the spring 18 needs to be replaced, only need to screw out the first screw 20 from the first thread groove 19, then the plugging sleeve 17, the spring 18 and the conductive rod 12 can be pulled out from the conductive rod mounting hole 27. Then cut the negative electrode wire 11 from the conductive rod 12, and the old spring 18 can be removed from the negative electrode wire 11. After sleeving the new spring 18 back on the negative electrode wire 11, fix the end of the negative electrode wire 11 on the conductive rod 12 again by welding. Then load the conductive rod 12, the spring 18 and the plugging sleeve 17 back into the conductive rod mounting hole 27 in turn, and finally tighten the first screw 20 in the first thread groove 19 to complete the replacement of the spring 18.

[0026] Embodiment 4: On the basis of Embodiment 3, in order to prevent accidental touch alarms, anti-slip grooves 24 are provided on the retaining ring 4. Anti-slip rings 25 are fixed in the anti-slip grooves 24. The anti-slip rings 25 have a circular plate structure. The outer ring of the anti-slip ring 25 abuts against the rotating seat 5. Damping sleeves 21 are sleeved on both ends of the resistor plate 9 extending out of the resistor plate insertion hole 8. The damping sleeves 21 have a "return" - shaped plate structure. The inner ring of the damping sleeve 21 has an interference fit with the resistor plate 9.

[0027] An anti-slip groove 24 is made on the retaining ring 4, and an anti-slip ring 25 is fixed in the anti-slip groove 24. The outer ring of the anti-slip ring 25 abuts against the inner wall of the rotating seat 5, thereby generating a large frictional force between the anti-slip ring 25 and the rotating seat 5, providing damping for the rotating seat 5 and preventing the rotating seat 5 from rotating under the action of small forces such as airflow, thus preventing false alarm. Similarly, a damping sleeve 21 is fitted on the resistor plate 9, so that a large frictional force is generated between the resistor plate 9 and the damping sleeve 21, so that when the distance of the resistor plate 9 extending from the resistor plate insertion hole 8 changes, it will be damped to a certain extent, preventing the resistor plate 9 from displacing under the action of small external forces such as its own weight, thus preventing false alarm.

[0028] In actual use, when constructing the tailings dam slope 1, multiple sets of base grooves 2 are evenly reserved. After the rotating seat 5 is fitted onto the base 3, the base 3 is placed in the base groove 2. The outer surface of the tailings dam slope 1 is formed by the drying of cement and other reinforcing materials. When the cement dries, the base 3 is solidified in the base groove 2. The rotating seat 5 cannot detach from the base 3 due to the obstruction of the retaining ring 4 and can only rotate around the base 3, thus realizing the layout of the rotating seat 5. The monitoring component mounting platform 7 is installed on the rotating seat 5, and then... The pull rope 26 between two adjacent sets of resistor plates 9 is taut and knotted; under normal conditions, the remote alarm module 14, positive wire 10, resistor plate 9, conductive rod 12, and negative wire 11 form a complete loop. The length of the resistor plate 9 connected to the loop will have a significant impact on the resistance value in the loop. The self-powered resistance detection device 13 can measure the resistance value in the loop. When the resistance value does not change significantly, the self-powered resistance detection device 13 will not supply power to the remote alarm module 14. When the tailings dam slope 1 When a landslide or tilt occurs at a certain location, the distance between the monitoring component mounting platform 7 at that location and the monitoring component mounting platform 7 at locations where no landslide or tilt has occurred increases. This causes the resistance plate 9 on that set of monitoring component mounting platforms 7 to pull against the resistance plates 9 on adjacent sets of monitoring component mounting platforms 7. This pulling force is much greater than the damping force of the damping sleeve 21 on the resistance plate 9, which in turn changes the distance the resistance plate 9 extends out of the resistance plate insertion hole 8 and also changes the length of the resistance plate 9 connected to the circuit. This causes a significant change in the resistance value in the circuit. After the resistance detection device 13 with its own power supply measures the significant change in resistance value, it supplies power to the remote alarm module 14 through the power supply line 16. After the remote alarm module 14 is powered on, it sends an alarm to the remote monitoring terminal connected to the remote alarm module 14 via a wireless signal. At the same time, the remote alarm module 14 supplies power to the audible and visual alarm 15, causing the audible and visual alarm 15 to emit audible and visual signals. The on-site alarm is triggered synchronously through the audible and visual signals, thereby realizing real-time automatic monitoring of the stability of the tailings dam slope 1.

When a landslide or tilt occurs at a certain part of the tailings dam slope (1), the distance between the monitoring component mounting platform (7) at that part and the monitoring component mounting platform (7) at the part that has not landslide or tilted increases, thereby causing the resistor plate (9) on that set of monitoring component mounting platforms (7) to pull against the resistor plates (9) on the adjacent sets of monitoring component mounting platforms (7). This pulling force is much greater than the damping sleeve (21) on the resistor plate (9). The damping of the resistor plate (9) causes the distance of the resistor plate (9) extending out of the resistor plate insertion hole (8) to change, and also causes the length of the resistor plate (9) connected to the circuit to change. This causes a large change in the resistance value in the circuit. After the self-powered resistance detection device (13) measures the large change in resistance value, it supplies power to the remote alarm module (14) through the power supply line (16). After the remote alarm module (14) is powered on, it alarms the remote monitoring terminal connected to the remote alarm module (14) through a wireless signal. At the same time, the remote alarm module (14) supplies power to the audible and visual alarm (15), so that the audible and visual alarm (15) emits audible and visual signals. The audible and visual signals are used to synchronously alarm on site, thereby realizing real-time automatic monitoring of the stability of the tailings dam slope (1).
