A mine ecological restoration device and restoration method

Abstract

This invention discloses a mine ecological restoration device and method, belonging to the field of soil remediation technology. It includes a frame and a vibration assembly slidably mounted on a mud rod. The vibration assembly is used to vibrate the conveyed mud and form a continuous fissure zone in the soil. The mud enters the mud rod and pushes a cross plate. A sliding pin on the cross plate pushes a sliding sleeve, causing the sleeve to slide on the outer edge of the mud rod. This brings the sliding sleeve and two fixed blocks on the mud rod closer together, causing the X-shaped cross frame to extend and push out the placement box, bringing the placement box closer to the borehole wall. During extension, the transfer rod on the placement box can be inserted into the borehole wall. The ultrasonic vibration generated by the ultrasonic generator causes minute vibrations in the mineral soil particles, increasing the permeability of the mineral soil and improving the soil structure, accelerating the penetration of the mud, and encapsulating the ore waste, preventing the release of highly toxic elements from the waste.

Description

Technical Field

[0001] This invention relates to the field of soil remediation technology, and in particular to a mine ecological restoration device and method. Background Technology

[0002] The key to ecological damage caused by mining is land degradation, which is the alteration of soil factors, specifically the deterioration of the physical and chemical properties of abandoned soil, nutrient loss, and the increase of toxic and harmful substances in the soil. Therefore, soil remediation is one of the most important aspects of ecological restoration of abandoned mining sites.

[0003] Before topsoil remediation, waste land remediation measures involve injecting mud to encapsulate the waste residue. However, the mud is difficult to spread into the surrounding soil layers and instead combines more with the loose soil inside the borehole, resulting in limited remediation capacity and low remediation efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the problem in existing waste land remediation measures where, before topsoil remediation, mud is injected to encapsulate waste residue, but the mud is difficult to diffuse into the surrounding soil layers and instead combines more with the loose soil inside the borehole, resulting in limited remediation capacity and low remediation efficiency. Therefore, this invention proposes a mine ecological restoration device and method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mine ecological restoration device includes a frame, on which a mud bucket is fixedly mounted via a first hydraulic cylinder and a telescopic rod. A mud rod is fixedly mounted on the mud bucket via a conveying pipe. The mud rod has a slurry outlet groove and a conveying pump is fixedly mounted on the mud rod. The device also includes a vibration component, which is slidably mounted on the mud rod. The vibration component is used to vibrate the conveyed mud and form a through-crack zone in the soil.

[0007] In order to induce minute vibrations in the mineral particles through ultrasonic vibration generated by the ultrasonic generator, thereby accelerating the penetration of the slurry, the vibration assembly preferably includes: a sliding sleeve slidably mounted on the slurry rod, a fixing block fixedly mounted on both the sliding sleeve and the slurry rod, an X-shaped cross bracket rotatably mounted between the two fixing blocks, a placement box rotatably mounted on the side of the X-shaped cross bracket away from the slurry rod, and an ultrasonic generator and a battery fixedly mounted inside the placement box, wherein the ultrasonic generator and the battery are electrically connected.

[0008] To bring the placement box closer to the borehole wall and improve ultrasonic transmission efficiency, a cross plate is slidably installed inside the mud rod. The end of the cross plate extends through the mud rod and is fixedly installed with a sliding pin. A groove adapted to the sliding pin is formed on the sliding sleeve. A sliding groove is formed on the sliding sleeve. A connecting pin is fixedly installed on the mud rod. A first spring is fixedly connected between the inner sidewall of the groove and the connecting pin.

[0009] To further increase the permeability of the mineral soil and improve the soil structure, the placement box is provided with an installation hole, and a transfer rod is fixedly installed in the installation hole.

[0010] To adjust the ultrasonic frequency for optimal efficiency, the system further includes: a circuit board fixedly installed inside the placement box, the circuit board being communicatively connected to the ultrasonic generator; and an adjustment knob fixedly installed on the frame, the adjustment knob being connected to the circuit board via a ribbon cable.

[0011] To create a continuous fracture zone between adjacent boreholes and tightly bond them together, reducing soil erosion, the system further includes: a sealing seat fixedly installed on the mud rod, with a support rod fixedly installed on the sealing seat along the circumferential direction; a flow groove is formed inside the sealing seat, and an arc-shaped plate is rotatably installed on the inner side wall of the flow groove; a push rod is fixedly installed on the arc-shaped plate, and the end of the push rod away from the arc-shaped plate passes through the flow groove and is fixedly installed with a sealing block, which is slidably installed on the sealing seat; a second spring is sleeved on the push rod, and the two ends of the second spring are fixedly connected to the sealing seat of the sealing block.

[0012] To achieve the purpose of re-covering the mine soil, a vertical shaft is rotatably mounted on the frame. A first conical tooth is fixedly mounted on one end of the vertical shaft near the telescopic rod. The first conical tooth is connected to the telescopic rod via a transmission component. An eccentric wheel is fixedly mounted on the other end of the vertical shaft. A second hydraulic cylinder is fixedly mounted inside the frame. The movable end of the second hydraulic cylinder extends through the bottom of the frame and is fixedly mounted with a soil covering component. The eccentric wheel abuts against the soil covering component. The soil covering component includes: an annular seat, a connecting shaft rotatably mounted on the annular seat in a circumferential direction, and a first gear and a scraper fixedly mounted on both ends of the connecting shaft, respectively. An annular plate is rotatably mounted on the annular seat, and the annular plate has a tooth groove adapted to the first gear.

[0013] To further increase the viscosity of the soil, a fertilizer box is fixedly installed on the frame, a piston plate is installed inside the fertilizer box, an air pipe is fixedly connected between one end of the fertilizer box and the telescopic rod, and a fertilizer pipe is fixedly connected between the other end of the fertilizer box and the annular seat.

[0014] In order to repeatedly press the mineral soil to turn the cohesive mineral soil into an artificial waterproof layer and reduce the infiltration of ground water, preferably, a crankshaft is rotatably installed inside the frame, the two ends of the crankshaft are connected to tires provided on the frame, a limit cylinder is fixedly installed at the bottom of the frame, a pressure block is slidably installed inside the limit cylinder, and a connecting rod is rotatably connected between the pressure block and the crankshaft.

[0015] A method for ecological restoration of mines, with the following steps:

[0016] Step 1: Drill holes in the abandoned mining area before restoration;

[0017] Step 2: Inject drilling mud into the borehole;

[0018] Step 3: Create a fracture zone between two adjacent boreholes;

[0019] Step 4: After covering with soil, an artificial waterproof barrier is formed.

[0020] Compared with the prior art, the present invention provides a mine ecological restoration device and restoration method, which has the following beneficial effects:

[0021] 1. In this mine ecological restoration device, mud enters the mud rod and pushes the cross plate. The sliding pin on the cross plate pushes the sliding sleeve, causing the sliding sleeve to slide on the outer edge of the mud rod. This brings the sliding sleeve and two fixed blocks on the mud rod closer together, causing the X-shaped cross frame to extend and push out the placement box, bringing the placement box closer to the borehole wall. During extension, the transfer rod on the placement box can be inserted into the borehole wall. The ultrasonic vibration generated by the ultrasonic generator causes the mineral soil particles to vibrate slightly, increasing the permeability of the mineral soil and improving the soil structure. This accelerates the penetration of the mud, allowing it to encapsulate the ore waste and prevent the release of highly toxic elements from the waste. At the same time, the ultrasonic vibration can remove air bubbles in the mud, making the mud injection more compact, thereby improving the strength and durability of the mud-mineral soil interface.

[0022] 2. In this mine ecological restoration device, mud rods are placed inside the borehole, and support rods on the sealing seat are located at the borehole opening for support and fixation. When the mud flows, it enters the flow channel inside the sealing seat and pushes open the arc plate, causing the arc plate to flip. The flipped arc plate pushes the push rod outward, and the push rod drives the sealing block to slide until it contacts the borehole wall. In this way, the inside of the borehole is basically formed into a relatively closed space. When mud is continuously injected into the borehole, the internal pressure causes cracks to appear in the borehole wall and extend outward. This forms a through-crack zone between adjacent boreholes and tightly encapsulates them together, reducing the loss of mineral soil.

[0023] 3. In this mine ecological restoration device, during mud injection, the first hydraulic cylinder pushes the mud bucket down. At this time, the air inside the telescopic rod is squeezed from the air pipe into the fertilizer box and pushes the piston plate. In this way, the fertilizer in the fertilizer box enters the annular seat from the fertilizer pipe and is sprayed onto the previously excavated soil through the nozzle on the annular seat to increase the viscosity of the soil. After the mud injection is completed, the first hydraulic cylinder pushes the mud bucket up to reset. At this time, the sliding rod inside the telescopic rod drives the meshing second gear to rotate and makes the eccentric wheel rotate. At the same time, the moving end of the second hydraulic cylinder pushes the annular seat to make the scraper contact the ground. The rotating eccentric wheel squeezes the annular plate on the annular seat. The tooth groove on the annular plate drives the meshing first gear to rotate. The rotating first gear drives the scraper to deflect towards the center of the annular seat, so as to achieve the purpose of re-covering the soil.

[0024] 4. After the soil is covered, the mine ecological restoration device is moved to the next borehole. The moving frame drives the crankshaft to rotate. The rotating crankshaft pushes the pressure block to reciprocate and press the soil through the connecting rod, so that the sticky soil becomes an artificial waterproof layer, reducing the infiltration of surface water and further preventing the release of highly toxic elements in the waste residue.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0038] Example 1:

[0039] Reference Figures 1-10 A mine ecological restoration device includes a frame 1, on which a mud tank 4 is fixedly installed via a first hydraulic cylinder 2 and a telescopic rod 3. A mud rod 6 is fixedly installed on the mud tank 4 via a conveying pipe 5. The mud rod 6 has a slurry outlet 601. A conveying pump 7 is fixedly installed on the mud rod 6. The device also includes a vibration component, which is slidably installed on the mud rod 6. The vibration component is used to vibrate the conveyed mud and form a through-crack zone in the soil.

[0040] It should be noted that the telescopic rod 3 and the first hydraulic cylinder 2 are alternately arranged. The telescopic rod 3 includes a base part that is fixedly installed on the frame 1 and a sliding rod part that slides in the base. The sliding rod part is fixedly connected to the mud bucket 4.

[0041] With the above structure, before the repair, the mine wasteland is drilled. The device is moved to the drilling site, and the mud bucket 4 is lowered by the first hydraulic cylinder 2 so that the mud rod 6 is inserted into the drilling hole. The mud in the mud bucket 4 is discharged into the drilling hole by the delivery pump 7 so that it covers the ore waste and prevents the release of highly toxic elements in the waste.

[0042] See Figure 1 and Figure 2 and Figure 3 and Figure 4 The vibration component includes: a sliding sleeve 8 slidably mounted on the mud rod 6, a fixing block 9 fixedly mounted on both the sliding sleeve 8 and the mud rod 6, an X-shaped cross bracket 10 rotatably mounted between the two fixing blocks 9, a placement box 11 rotatably mounted on the side of the X-shaped cross bracket 10 away from the mud rod 6, an ultrasonic generator 12 and a battery fixedly mounted inside the placement box 11, and an ultrasonic generator 12 and a battery electrically connected.

[0043] A cross plate 13 is slidably installed inside the mud rod 6. The end of the cross plate 13 passes through the mud rod 6 and is fixedly installed with a sliding pin 1301. A groove 801 adapted to the sliding pin 1301 is opened on the sliding sleeve 8. A sliding groove 802 is opened on the sliding sleeve 8. A connecting pin 602 is fixedly installed on the mud rod 6. A first spring 803 is fixedly connected between the inner side wall of the groove 802 and the connecting pin 602.

[0044] The placement box 11 has a mounting hole 1101, and a transfer rod 14 is fixedly installed in the mounting hole 1101.

[0045] With the above structure, the mud enters the mud rod 6 and pushes the cross plate 13. The sliding pin 1301 on the cross plate 13 pushes the sliding sleeve 8 so that the sliding sleeve 8 slides on the outer edge surface of the mud rod 6. In this way, the sliding sleeve 8 and the two fixing blocks 9 on the mud rod 6 approach each other and extend the X-shaped cross frame 10 and push out the placement box 11, so that the placement box 11 is closer to the borehole wall. When it extends, the transfer rod 14 on the placement box 11 can be inserted into the borehole wall. The ultrasonic vibration generated by the ultrasonic generator 12 will cause the mineral soil particles to vibrate slightly, increase the permeability of the mineral soil and improve the soil structure, and accelerate the infiltration of the mud.

[0046] At the same time, ultrasonic vibration can remove air bubbles in the mud, making the mud injection more compact, thereby improving the strength and durability of the mud-soil interface.

[0047] Example 2:

[0048] See Figures 1-10 The solution is basically the same as in Example 1, but the entire technical solution has been further optimized based on Example 1.

[0049] See Figure 3 The implementation scheme for adjusting the ultrasonic frequency has been improved, and it also includes: a circuit board 15 fixedly installed in the placement box 11, which is connected to the ultrasonic generator 12; and an adjustment knob 16 fixedly installed on the frame 1, which is connected to the circuit board 15 via a ribbon cable.

[0050] With the above structure, the output power can be changed by adjusting the knob 16 according to the properties of the mineral soil. The cable can transmit the command of the adjusting knob 16 to the ultrasonic generator 12 through the circuit board 15 to control the transmission frequency of the ultrasonic generator 12 in order to achieve optimal efficiency.

[0051] Example 3:

[0052] See Figures 1-10 The solution is basically the same as in Example 2, but the entire technical solution has been further optimized based on Example 2.

[0053] See Figure 1 and Figure 5 and Figure 6 The proposed solution enhances the connection between adjacent boreholes and includes: a sealing seat 17 fixedly mounted on the mud rod 6, with a support rod 18 fixedly mounted on the sealing seat 17 along the circumferential direction; a flow groove 1701 is provided inside the sealing seat 17, an arc plate 19 is rotatably mounted on the inner side wall of the flow groove 1701, a push rod 20 is fixedly mounted on the arc plate 19, one end of the push rod 20 away from the arc plate 19 passes through the flow groove 1701 and is fixedly mounted with a sealing block 21, the sealing block 21 is slidably mounted on the sealing seat 17; a second spring 2001 is sleeved on the push rod 20, and the two ends of the second spring 2001 are fixedly connected to the sealing seat 17 of the sealing block 21 respectively.

[0054] With the above structure, the mud rod 6 is placed inside the borehole, and the support rod 18 on the sealing seat 17 is located at the borehole opening end for support and fixation. When the mud flows, it enters the flow groove 1701 inside the sealing seat 17 and pushes open the arc plate 19, causing the arc plate 19 to flip. The flipped arc plate 19 pushes the push rod 20 outward, and the push rod 20 drives the sealing block 21 to slide until it contacts the borehole wall. In this way, the inside of the borehole is basically formed into a relatively closed space. When mud is continuously injected into the borehole, the internal pressure causes cracks in the borehole wall and extends outward. In this way, a through fracture zone is formed between adjacent boreholes and they are tightly cast together, reducing the loss of mineral soil.

[0055] Example 4:

[0056] See Figures 1-10 The solution is basically the same as in Example 3, but the entire technical solution has been further optimized based on Example 3.

[0057] See Figure 7 and Figure 8 and Figure 9 The specific implementation plan for improving the cohesiveness of the soil has been added. A vertical shaft 22 is rotatably mounted on the frame 1. A first conical tooth 2201 is fixedly mounted on one end of the vertical shaft 22 near the telescopic rod 3. The first conical tooth 2201 is connected to the telescopic rod 3 through a transmission component. An eccentric wheel 2203 is fixedly mounted on the other end of the vertical shaft 22. A second hydraulic cylinder 23 is fixedly mounted inside the frame 1. The movable end of the second hydraulic cylinder 23 passes through the bottom of the frame 1 and is fixedly mounted with a soil covering component. The eccentric wheel 2203 abuts against the soil covering component. The soil covering component includes: an annular seat 24. A connecting shaft 25 is rotatably mounted on the annular seat 24 in the circumferential direction. A first gear 26 and a scraper 27 are fixedly mounted on both ends of the connecting shaft 25, respectively. An annular plate 2401 is rotatably mounted on the annular seat 24. The annular plate 2401 has a tooth groove that matches the first gear 26.

[0058] See Figure 7 The transmission component includes a support seat 2202 fixedly mounted on the frame 1. A second gear 2204 and a second conical tooth 2205 are rotatably mounted on the support seat 2202 and are coaxially arranged. The second conical tooth 2205 meshes with the first conical tooth 2201. A through groove is provided in the base part of the telescopic rod 3, and a tooth groove that can mesh with the second gear 2204 is provided on the slide of the telescopic rod 3. In this way, when the telescopic rod 3 moves in a straight line, the vertical shaft 22 is rotated through the transmission component and the rotational force is transmitted to the eccentric wheel 2203.

[0059] A fertilizer box 28 is fixedly installed on the frame 1. A piston plate 2801 is installed inside the fertilizer box 28. An air pipe 29 is fixedly connected between one end of the fertilizer box 28 and the telescopic rod 3. A fertilizer pipe 30 is fixedly connected between the other end of the fertilizer box 28 and the annular seat 24.

[0060] With the above-described structure, during mud injection, the first hydraulic cylinder 2 pushes the mud bucket 4 down. At this time, the air inside the telescopic rod 3 is squeezed from the air pipe 29 into the fertilizer box 28 and pushes the piston plate 2801. Thus, the fertilizer in the fertilizer box 28 enters the annular seat 24 from the fertilizer pipe 30 and is sprayed onto the previously excavated soil through the nozzle on the annular seat 24 to increase the viscosity of the soil. After the mud injection is completed, the first hydraulic cylinder 2 pushes the mud bucket 4 up to reset. At this time, the sliding rod inside the telescopic rod 3 drives the meshing second gear 2204 to rotate and the eccentric wheel 2203 to rotate. Simultaneously, the moving end of the second hydraulic cylinder 23 pushes the annular seat 24 to make the scraper 27 contact the ground. The rotating eccentric wheel 2203 squeezes the annular plate 2401 on the annular seat 24. The tooth groove on the annular plate 2401 drives the meshing first gear 26 to rotate. The rotating first gear 26 drives the scraper 27 to deflect towards the center of the annular seat 24, achieving the purpose of re-covering the soil.

[0061] It should be noted that an air inlet is provided on the telescopic rod 3. One-way valves with opposite working directions are fixedly installed in both the air inlet and the air pipe 29. In this way, when the telescopic rod 3 is compressed, the air inside can only be discharged from the air pipe 29, and when the telescopic rod 3 is stretched, the air outside can only enter from the air inlet.

[0062] Example 5:

[0063] See Figures 1-10 The solution is basically the same as in Example 4, but the entire technical solution has been further optimized based on Example 4.

[0064] See Figure 1 and Figure 7 The specific implementation plan for improving the compaction of the soil has been added. A crankshaft 31 is rotatably installed inside the frame 1. The two ends of the crankshaft 31 are connected to the tires provided on the frame 1. A limit cylinder 32 is fixedly installed at the bottom of the frame 1. A pressure block 33 is slidably installed inside the limit cylinder 32. A connecting rod 34 is rotatably connected between the pressure block 33 and the crankshaft 31.

[0065] With the above structure, after the soil is covered, the moving device moves to the next borehole. The moving frame 1 drives the crankshaft 31 to rotate. The rotating crankshaft 31 pushes the pressure block 33 to reciprocate and press the soil through the connecting rod 34, so that the sticky soil becomes an artificial waterproof layer, reducing the infiltration of ground water and further preventing the release of highly toxic elements in the waste residue.

[0066] A method for ecological restoration of mines, with the following steps:

[0067] Step 1: Drill holes in the abandoned mining area before restoration;

[0068] Step 2: The first hydraulic cylinder 2 pushes the mud bucket 4 down, causing the mud rod 6 to be inserted into the borehole. The mud in the mud bucket 4 is discharged into the borehole by the delivery pump 7. The mud enters the mud rod 6 and pushes the cross plate 13. The sliding pin 1301 on the cross plate 13 pushes the sliding sleeve 8, causing the sliding sleeve 8 to slide on the outer edge of the mud rod 6. In this way, the sliding sleeve 8 and the two fixing blocks 9 on the mud rod 6 move closer to each other, and the X-shaped cross frame 10 extends and pushes out the placement box 11, so that the placement box 11 is closer to the borehole wall. When it extends, the transfer rod 14 on the placement box 11 can be inserted into the borehole wall. The ultrasonic vibration generated by the ultrasonic generator 12 will cause the mineral soil particles to vibrate slightly, increasing the permeability of the mineral soil and improving the soil structure, thus accelerating the penetration of the mud. At the same time, the ultrasonic vibration can remove air bubbles in the mud, making the mud injection more compact, thereby improving the strength and durability of the mud-mineral soil interface.

[0069] Step 3: During mud injection, the first hydraulic cylinder 2 pushes the mud bucket 4 down. At this time, the air inside the telescopic rod 3 is squeezed from the air pipe 29 into the fertilizer box 28 and pushes the piston plate 2801. In this way, the fertilizer in the fertilizer box 28 enters the annular seat 24 from the fertilizer pipe 30 and is sprayed from the nozzle on the annular seat 24 onto the previously excavated soil to increase the viscosity of the soil.

[0070] Step 4: According to the properties of the mineral soil, the output power is changed by adjusting knob 16. The ribbon cable can transmit the command of adjusting knob 16 to ultrasonic generator 12 through circuit board 15 to control the transmission frequency of ultrasonic generator 12 in order to achieve optimal efficiency.

[0071] Step 5: The mud rod 6 is placed inside the borehole. The support rod 18 on the sealing seat 17 is located at the borehole opening end for support and fixation. When the mud flows, it enters the flow groove 1701 inside the sealing seat 17 and pushes open the arc plate 19, causing the arc plate 19 to flip. The flipped arc plate 19 pushes the push rod 20 outward. The push rod 20 drives the sealing block 21 to slide until it contacts the borehole wall. In this way, the inside of the borehole is basically formed into a relatively closed space. When mud is continuously injected into the borehole, the internal pressure causes cracks in the borehole wall and extends outward. This forms a through fracture zone between adjacent boreholes and tightly casts them together, reducing the loss of mineral soil.

[0072] Step 6: After the mud injection is completed, the first hydraulic cylinder 2 pushes the mud bucket 4 to rise and reset. At this time, the sliding rod inside the telescopic rod 3 drives the meshing second gear 2204 to rotate and the eccentric wheel 2203 to rotate. At the same time, the moving end of the second hydraulic cylinder 23 pushes the annular seat 24 to make the scraper 27 contact the ground. The rotating eccentric wheel 2203 squeezes the annular plate 2401 on the annular seat 24. The tooth groove on the annular plate 2401 drives the meshing first gear 26 to rotate. The rotating first gear 26 drives the scraper 27 to deflect towards the center of the annular seat 24, so as to achieve the purpose of re-covering the mineral soil. After covering the soil, the moving device moves to the next borehole. The moving frame 1 drives the crankshaft 31 to rotate. The rotating crankshaft 31 pushes the pressure block 33 to reciprocate and press the mineral soil through the connecting rod 34, so that the sticky mineral soil becomes an artificial waterproof layer, reducing the infiltration of ground water and further preventing the release of highly toxic elements in the waste residue.
