Abstract
Description
Technical Field
[0001] The invention relates to the technical field of slope support, and in particular to an open-pit mine slope landslide prevention structure and a construction method. Background Art
[0002] Open-pit mining, especially open-pit coal mining, is a common way of mining mineral resources. It involves stripping the soil and rocks on the surface and mining directly on the ore bed. This process usually involves dividing the mine field into multiple horizontal layers, mining layer by layer from top to bottom, and finally forming a series of stepped slopes on the surface. These slopes are subjected to various natural forces such as gravity, weathering, and rainfall under natural conditions, and are prone to rock slides, which not only pose a threat to mining operations, but may also have a significant impact on the surrounding environment and personnel safety.
[0003] In order to prevent rocks from sliding down the slope, open-pit coal mines generally use protective nets to cover the slope surface. The protective net is generally made of high-strength metal or polymer materials, and is fixed at the upper and lower ends of the slope to form a barrier to intercept rocks. However, this protection method has obvious shortcomings. For example, the protective net has a good interception effect on small rocks or gravel, but for large and heavy falling rocks, the interception effect of the protective net is limited. The huge kinetic energy carried by large falling rocks during the sliding process can often easily penetrate or destroy the protective net and continue to slide down, thus posing a safety hazard.
[0004] In order to solve the above problem, some existing solutions also use baffles for interception. However, in actual use, since the falling rocks have great kinetic energy when sliding down the slope, they are easy to knock down the baffles, so the service life is short. Summary of the invention

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0031] See also Figures 1 to 5As shown, according to an embodiment of the present invention, an open-pit mine slope anti-landslide structure includes: a base 1, a bottom bar 2 is provided on the upper side of the base 1, a slider 3 is slidably fitted in the bottom bar 2, an adjustment mechanism 4 for adjusting the sliding position of the slider 3 is provided in the bottom bar 2, a first baffle 5 is rotatably fitted at one end of the upper side of the bottom bar 2, a second baffle 6 is slidably provided in the first baffle 5, a first positioning handle screw 7 for positioning the first baffle 5 is threadedly fitted on one side of the first baffle 5, a baffle plate 8 is provided on the side of the first baffle 5 facing away from the bottom bar 2, a buffer member 9 is provided on the side of the second baffle 6 facing away from the bottom bar 2, and a support bar 10 is hinged between the slider 3 and the first baffle 5.
[0032] The cooperation between the base 1 and the bottom bar 2 provides a stable base for the entire structure. The sliding cooperation of the slider 3 in the bottom bar 2, coupled with the use of the adjustment mechanism 4, enables the sliding position of the slider 3 to be precisely adjusted, thereby controlling the position and inclination of the first baffle 5. This design allows the structure to be adjusted according to the specific conditions of the slope, thereby enhancing stability and applicability. The first baffle 5 is rotated and matched with the bottom bar 2 through one end thereof, thereby adjusting the contact angle with the slope. The second baffle 6 arranged internally for sliding cooperates with one side of the first baffle 5 and is fixed by the first positioning handle screw 7, so that the height of the second baffle 6 can be adjusted, thereby fine-tuning the position of the buffer 9. This ability to fine-tune the angle and position enables the structure to better adapt to slopes of different inclinations and improve the anti-landslide effect. The setting of the baffle 8 and the buffer 9 forms a double-layer protection system. The baffle 8 is directly located at the bottom of the slope, which can effectively block the displacement of the bottom of the slope and reduce the risk of large-scale landslides. The buffer 9 is located on the side of the second stop bar 6 away from the bottom bar 2, and can absorb the impact of falling rocks through the buffer block 902 inside it, reducing damage to the structure. The support bar 10 is hinged between the slider 3 and the first stop bar 5, ensuring the smooth transmission of force and the stable connection between the first stop bar 5 and the slider 3.
[0033] The anti-slope landslide structure of the open-pit mine slope uses the adjustment mechanism 4 on the base 1 to adjust the position of the slider 3 in the bottom bar 2, and uses the position adjustment of the slider 3 in the bottom bar 2 to adjust the connection position of the support bar 10 on the base 1, and uses the first baffle 5 to realize the hinge connection with the support bar 10, so as to use the position adjustment of the slider 3 in the bottom bar 2 to drive the support bar 10 to move, and adjust the angle between the first baffle 5 and the bottom bar 2 so that the inclination angle of the first baffle 5 can match the inclined surface of the mine slope structure, thereby ensuring that the baffle plate arranged on the side of the first baffle 5 away from the bottom bar 2 and the inclination angle of the buffer member 9 on the side of the second baffle 6 away from the bottom bar 2 can match the inclined surface of the mine slope structure, forming a barrier to the bottom of the mine slope, effectively preventing the probability of landslide on the mine slope, and at the same time using the buffer member 9 to block and buffer the falling rocks, reduce the impact of the falling rocks on the mine slope on the first baffle 5 and the second baffle 6, form effective buffer protection for the first baffle 5 and the second baffle 6, and extend the service life of the anti-slope landslide structure of the open-pit mine slope.
[0034] In one embodiment, the adjustment mechanism 4 includes a sliding bar 401 that is slidably fitted in the bottom bar 2, an adjustment component 402 arranged in the bottom bar 2 for adjusting the sliding position of the sliding bar 401, and a first T-shaped groove 403 arranged on the upper side of the sliding bar 401. The slider 3 is a T-shaped block structure, and the slider 3 is slidably fitted in the first T-shaped groove 403. The upper side of the slider 3 is threaded with a second positioning handle screw 404, and the bottom surface of the inner wall of the first T-shaped groove 403 is provided with a plurality of second positioning grooves 405 that cooperate with the second positioning handle screw 404 along the length direction.
[0035] The combination of the sliding fit of the sliding bar 401 in the bottom bar 2 and the adjustment component 402 provides a mechanism for precisely adjusting the position of the sliding bar 401. This design allows the operator to fine-tune the position of the sliding bar 401 according to actual needs, thereby affecting the position of the slider 3 and the inclination of the entire structure to adapt to slopes of different angles and heights, thereby improving the applicability and accuracy of the anti-slip structure. The first T-shaped groove 403 set on the upper side of the sliding bar 401 cooperates with the slider 3 of the T-shaped block structure to ensure the stability and guidance of the slider 3 when sliding. The cooperation of the second positioning handle screw 404 and the plurality of second positioning grooves 405 allows the slider 3 to be firmly positioned after being adjusted in place, preventing automatic movement under external impact or environmental changes, thereby ensuring the stability and safety of the structure. The sliding bar 401 is adjusted through the adjustment component 402, and the adjustment is transmitted through the hinged support bar 10 between the slider 3 and the first stop bar 5. The design of the entire adjustment mechanism 4 ensures the flexibility and reliability of operation. The operator can select and fix multiple second positioning slots 405 on the slide bar 401 by simply rotating the second positioning handle screw 404, and achieve fine position adjustment without worrying about instability during the adjustment process or position offset of the slider 3 after adjustment. The T-shaped structural design of the slider 3 and the slide bar 401 is easy to identify and adjust during operation, reducing the complexity of maintenance and adjustment. The cooperation of the second positioning handle screw 404 and the second positioning slot 405 provides an intuitive and easy-to-operate positioning method, allowing maintenance personnel to quickly and accurately adjust the structure.
[0036] In one embodiment, a second T-shaped groove 201 is provided on the upper side of the bottom bar 2 , and the sliding bar 401 is a T-shaped long strip structure, and the sliding bar 401 is slidably fitted in the second T-shaped groove 201 .
[0037] The design of the second T-shaped groove 201 provides precise guidance for the sliding bar 401, ensuring its stability during the sliding process. This guiding mechanism reduces the lateral displacement that the sliding bar 401 may encounter when sliding, and enhances the rigidity and reliability of the entire structure. The sliding cooperation between the T-shaped sliding bar 401 and the second T-shaped groove 201 allows the sliding bar 401 to slide freely along its length. This design allows the operator to flexibly adjust the position of the sliding bar 401 according to the specific conditions of the mine slope, thereby affecting the positioning of the slider 3 and the inclination angle of the first and second bars 5 and 6, thereby improving the adaptability and effectiveness of the anti-slip structure. The sliding bar 401 sliding in the second T-shaped groove 201 can be locked in place by the adjustment handle bolt 4022 in the adjustment assembly 402. This ensures that the position of the sliding bar 401 will not change unexpectedly when subjected to external loads or environmental changes, thereby maintaining the fixed inclination of the first and second bars 5 and 6, and enhancing the overall stability and protective effect of the anti-slip structure.
[0038] In one embodiment, the adjustment component 402 includes a bearing seat 4021 disposed at both ends of the second T-shaped groove 201, a bearing disposed in the bearing seat 4021, and an adjustment handle bolt 4022 that is rotatably engaged with the sliding bar 401 threadedly in the second T-shaped groove 201, and optical axis sections are provided on the outer sides of both ends of the adjustment handle bolt 4022, and the optical axis sections at both ends of the adjustment handle bolt 4022 are respectively fixed in the bearings.
[0039] The bearing seat 4021 is arranged at both ends of the second T-shaped groove 201, and a bearing is installed inside. This design provides a stable support for the rotation of the adjustment handle bolt 4022, ensuring low friction and high stability of the adjustment handle bolt 4022 during the rotation process. The smooth shaft section, that is, the shaft section with a smooth surface is fixed in the bearing, which further enhances the smoothness during rotation, and prevents the adjustment handle bolt 4022 from axial displacement during the rotation process, ensuring the accuracy and reliability of the adjustment process. The adjustment handle bolt 4022 and the sliding bar 401 are threadedly matched, so that the rotation of the adjustment handle bolt 4022 can directly drive the sliding bar 401 to move along the length direction of the second T-shaped groove 201. This direct force transmission mechanism, combined with the smooth rotation provided by the bearing seat 4021 and the bearing, makes the position adjustment of the sliding bar 401 both accurate and stable, without worrying about errors caused by friction or instability during the adjustment process. The adjustment component 402 with this design not only ensures the smooth movement and precise positioning of the sliding bar 401, but also simplifies the operation process. The operator can adjust the position of the slide bar 401 by simply rotating the adjustment handle bolt 4022, thereby adjusting the inclination of the anti-slip structure to adapt to different conditions of the mine slope. At the same time, the arrangement of the bearing seat 4021 and the bearing reduces friction and wear during the adjustment process, and prolongs the service life of the adjustment component 402.
[0040] In one embodiment, a third T-shaped groove 501 is provided on one side of the first stop bar 5 , and the second stop bar 6 is a T-shaped long strip structure, and the second stop bar 6 is slidably fitted in the third T-shaped groove 501 .
[0041] The shape design and sliding fit of the third T-shaped groove 501 and the second baffle 6 ensure the stable movement of the second baffle 6 on the first baffle 5. The design of the T-shaped structure, on the one hand, provides a guiding effect, reduces the deviation of the second baffle 6 during the sliding process, and enhances the stability of the structure; on the other hand, the T-shaped design increases the rigidity of the structure, prevents the second baffle 6 from being deformed when subjected to external pressure, thereby maintaining the effectiveness and protective effect of the structure.
[0042] This sliding fit design allows the second baffle 6 to adjust its position according to the specific conditions of the mine slope, such as the inclination angle and height difference, thereby improving the adaptability and flexibility of the anti-landslide structure, enabling it to better fit the surface of the mine slope and reduce the probability of landslides.
[0043] The cooperation between the first baffle 5 and the second baffle 6, through the guidance and sliding of the third T-shaped groove 501, combined with the locking function of the first positioning handle screw 7 and the first positioning groove 601, allows the entire structure to be firmly maintained in the adjusted position after adjustment, avoiding changes in the structural position caused by external factors, thereby ensuring the continued effectiveness of the anti-slip structure.
[0044] In one embodiment, a plurality of first positioning grooves 601 are provided on one side of the second stop bar 6 along the height direction, and the first positioning handle screw 7 can be selectively connected to at least one of the first positioning grooves 601 .
[0045] By setting a plurality of first positioning grooves 601 in the height direction of the second baffle bar 6, the operator can flexibly adjust the height of the second baffle bar 6 to adapt to the specific conditions of different mine slopes. The cooperation between the first positioning handle screw 7 and the first positioning groove 601 provides a stable locking mechanism. After adjusting the second baffle bar 6 to the desired position, the operator tightens the first positioning handle screw 7 to embed it into the corresponding first positioning groove 601, thereby stably locking the adjusted state. The selective connection of the first positioning handle screw 7 makes the operation of adjusting the height of the second baffle bar 6 simple and intuitive. The operator only needs to rotate the first positioning handle screw 7, move it to the appropriate first positioning groove 601, and then tighten it to complete the height adjustment and locking. The design of multiple first positioning grooves 601 allows the operator to quickly reposition the second baffle bar 6 to another first positioning groove 601 when the structure needs maintenance or adjustment to adapt to new needs or changes in conditions.
[0046] In one embodiment, the buffer member 9 includes a mounting box 901 disposed on one side of the two second baffles 6 and a buffer block 902 disposed in the mounting box 901 . The mounting box 901 has an opening on one side away from the second baffles 6 , and the buffer block 902 is located in the opening.
[0047] As the bearing body of the buffer block 902, the installation box 901 not only provides a stable installation environment, but also ensures the stability of the buffer block 902 when it is subjected to impact through its structural design. The buffer block 902 is located in the opening of the installation box 901. This design enables the buffer block 902 to displace and absorb energy within a preset range when it is impacted by falling rocks, while maintaining the stability of the overall structure and preventing structural damage caused by impact. The design of the buffer block 902 being located in the opening means that when the buffer block 902 is maintained and replaced, there is no need to disassemble the entire buffer component 9 or the anti-slip structure. It is only necessary to directly replace or adjust the buffer block 902 from the opening, which greatly simplifies the maintenance process, reduces maintenance costs, and improves the maintenance efficiency of the entire system.
[0048] In one embodiment, a plurality of pressure sensors 903 are disposed on a side of the installation box 901 away from the buffer block 902 , and a level meter 904 is disposed on a side of the installation box 901 away from the buffer block 902 .
[0049] The installation box 901 is designed with an opening on one side away from the second baffle 6, which is convenient for installing and maintaining the pressure sensor 903 and the level 904 behind the buffer block 902. These sensors can monitor the pressure and displacement of the buffer block 902 and the tilt state of the entire buffer 9 in real time, providing the operator with real-time feedback on the bottom state of the mine slope, facilitating timely reinforcement or preventive measures, and increasing the early warning function and safety of the system. The design of the installation box 901 integrates the buffer block 902, the pressure sensor 903 and the level 904, which not only realizes integration in function, but also optimizes space. This design enables the entire buffer 9 to simultaneously realize multiple functions of buffering, monitoring and early warning in a limited space, thereby improving the system's integration and space utilization.
[0050] In one embodiment, four threaded holes are provided on the upper side of the base 1, and a screw 101 is fitted in the inner thread of the threaded hole. A drill bit 102 is provided at the bottom end of the screw 101, a handwheel 103 is provided on the upper side of the screw 101, a sprocket 104 is provided on the upper fixed sleeve of the screw 101, and a chain 105 is provided for transmission between the four sprockets 104.
[0051] The four threaded holes on the upper side of the base 1 cooperate with the threads of the screw rod 101, providing an effective mechanism for fixing the anti-slip structure to the ground. The drill bit 102 at the bottom of the screw rod 101 can drill into the ground to expand the installation hole, ensure the stable implantation of the screw rod 101, and then the base 1 and the entire structure can be firmly fixed at the preset installation position, thereby enhancing the stability and reliability of the structure.
[0052] The hand wheel 103 on the upper side of the screw rod 101 and the transmission cooperation between the upper sprocket wheel 104 and the chain 105 provide a convenient solution for fine adjustment of the position of the base 1. By rotating any hand wheel 103, the transmission of the sprocket wheel 104 and the chain 105, the four screw rods 101 can be driven to fine adjust their extension lengths at the same time, so as to achieve fine adjustment of the horizontal level of the base 1 or precise adjustment of the tilt angle.
[0053] The integrated design of the four threaded holes of the base 1 and the screw 101, sprocket 104 and chain 105 not only realizes the combination of stable installation and fine-tuning functions in structure, but also optimizes the space. This compact design reduces the occupancy of ground space and improves the adaptability and installation convenience of the anti-landslide structure under complex terrain conditions.
[0054] The setting of the handwheel 103 and the sprocket 104 allows the operator to adjust the position of a single screw rod 101 by simply rotating the handwheel 103 when the structure needs maintenance or adjustment, thereby being able to simultaneously adjust the positions of other screw rods 101 without the need for complicated disassembly and reassembly processes, thereby improving maintenance efficiency and adjustment convenience.
[0055] According to an embodiment of the present invention, a construction method applicable to the above-mentioned open-pit mine slope anti-landslide structure comprises the following steps:
[0056] Step 1: Modify the mine slope into a smooth surface. According to the original inclination of the mine slope, cut off the raised part to form a smooth surface. During the cutting process, there is no need to repair the mine slope into a vertical surface, which is convenient for reducing the processing cost of the mine slope. Modifying the mine slope into a smooth surface, using the original inclination and cutting only the raised part, this strategy not only simplifies the pretreatment steps of the mine slope, but also significantly reduces the processing cost, avoids unnecessary flattening of vertical surfaces, maintains the natural form of the mine slope, and reduces damage to the environment.
[0057] Step 2: Install the equipment at the ground installation location, preset a mounting hole smaller than the diameter of the drill bit 102 at the ground installation location, move the base 1 to the installation position, and then turn any hand wheel 103, and drive the four screws 101 to rotate simultaneously through the sprocket 104 and the chain 105, and the drill bit 102 is transferred into the installation hole, and the installation hole is expanded, and the screw 101 and the base 1 are threadedly matched until the sprocket 104 fits the base 1, and the installation of the base 1 is completed. The installation hole is preset on the ground, and the screw 101, drill bit 102, hand wheel 103, sprocket 104 and chain 105 on the base 1 are matched to achieve a stable connection between the equipment and the ground. This design ensures the stability of the equipment during the landslide prevention process of the mine slope, and also simplifies the installation process and improves the installation efficiency.
[0058] Step 3: Adjust the inclination of the first stop bar 5 and the second stop bar 6, turn the second positioning handle screw 404 to release the limit of the slider 3, and position the slider 3. By adjusting the inclination of the first stop bar 5 and the second stop bar 6, and using the second positioning handle screw 404 to release the limit and position the slider 3, this series of operations enables the anti-slide structure to flexibly adapt to the specific conditions of the mine slope, thereby improving the adaptability and protection effect of the structure.
[0059] Step 4: adjust the height of the second baffle 6, prepare the baffle plate 8 and the buffer member 9, turn the first positioning handle screw 7, release the limit of the second baffle 6, and then slide the second baffle 6 to make the height of the second baffle 6 higher than the smooth surface of the mine slope, install the buffer member 9 on the second baffle 6, cut the baffle plate 8 according to the height difference between the buffer member 9 and the ground, and then install the baffle plate 8 on the first baffle 5;
[0060] Step five, fine-tune the baffle 8 and the buffer 9 so that the edge of at least one of the baffle 8 and the buffer 9 fits with the smooth surface of the mine slope, then rotate the adjustment handle bolt 4022 to drive the sliding bar 401, and the sliding bar 401 drives the baffle 8 and the buffer 9 to completely fit with the smooth surface of the mine slope through the slider 3 and the support bar 10, and then weld the adjustment handle bolt 4022 and the sliding bar 401 together.
[0061] By adjusting the height of the second baffle 6, installing and cutting the baffle 8, and installing the buffer 9, and by adjusting the handle bolt 4022 to drive the sliding bar 401 for fine adjustment, it is ensured that the baffle 8 and the buffer 9 are completely in contact with the smooth surface of the mine slope, thereby enhancing the sealing and protection capabilities of the protective structure. This design enables the structure to accurately adapt to the surface of the mine slope after installation, reducing the risk of displacement and landslide.
[0062] During the entire construction process, the coordination and adjustment of multiple components not only ensured the stability of the anti-slip structure during installation, but also improved the protection capability and reliability of the structure in long-term use through the monitoring of the buffer block 902, pressure sensor 903, and level gauge 904 in the buffer 9. The fit of the buffer 9 and the baffle 8, as well as the fine-tuning of the buffer 9, enabled the structure to effectively cope with the impact of falling rocks, while monitoring the bottom state of the mine slope and providing early warning, ensuring the long-term stability and safety of the entire anti-slip system.
[0063] Through the above operation, it is convenient to block the displacement of the bottom of the mine slope through the lower part of the buffer 9 and the baffle 8, thereby reducing the probability of large-scale landslides caused by the displacement of the bottom of the mine slope; it is convenient to block falling rocks through the upper part of the buffer 9, and detect the pressure on the buffer 9 through the pressure sensor 903, and judge the bottom state of the mine slope according to the pressure of the buffer 9; it is convenient to check and detect whether the buffer 9 is tilted due to excessive pressure at the bottom of the mine slope through the level 904, and to reinforce it in time or prepare anti-landslide equipment in advance; it is convenient to use the buffer block 902 in the buffer 9 to buffer the impact force of falling rocks, thereby reducing the probability of the buffer 9 being damaged.
