Description

Technical Field

[0001] The invention belongs to the technical field of temporary road construction, in particular to a device and method for laying the bottom of a road for mechanical mining and transportation of tailings. Background Art

[0002] Tailings are waste products discharged after ore is ground and useful components are selected. Currently, there are large amounts of tailings accumulated and stored in tailings ponds in my country. As an artificial secondary resource, tailings can be used as roadbed filling, building materials, etc.

[0003] In the recovery of tailings, mechanical recovery method is widely used because of its simple process, low labor intensity, and easy installation and management. Mechanical recovery method generally uses excavators and transportation systems, and is combined with regional layer-by-layer recovery to achieve the recovery of tailings in the tailings pond. In this process, due to the low and uneven bearing capacity of the accumulated tailings, and the heavy weight of excavators and transport vehicles, in order to reduce the probability of tailings layer collapse and vehicles getting stuck in tailings, and to improve vehicle driving efficiency, it is usually necessary to build temporary roads in the tailings pond during tailings mining. The temporary roads are made of hard materials such as steel plates as the main materials. By increasing the contact area with the tailings, the gravity of the vehicle is dispersed. However, in actual application, it is found that when the temporary road is built, one side relies on the hillside or bank to enhance the stability of the temporary road. When heavy objects are pressed on the temporary road, it is easy to cause the tailings under the temporary road to shift sideways, and eventually cause the temporary road to tilt to one side and collapse.

[0004] For example, the Chinese patent with the authorization publication number CN119507290A discloses a method for paving a temporary road for traffic on a sandy foundation based on high-strength polyethylene material. The patent scheme uses a vibratory roller to statically press the sandy foundation, and then vibrates and compacts it, and drives steel pipes into the sandy foundation for reinforcement. The flatness of the sandy foundation surface is measured using a measuring instrument, and a grader is used for trimming. According to the road design requirements, appropriate transverse and longitudinal slopes are set, and then high-strength polyethylene boards are laid on the surface of the sandy foundation. When designing the tailings recovery road construction with reference to this scheme, it was found that when tailings are recovered, the temporary road needs to be easy to disassemble and reinstall so that the height of the road can be easily adjusted during layer-by-layer mining. The road construction in this scheme is too troublesome, so it is not suitable for tailings recovery technology.

[0045] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0046] like Figures 1 to 8 As shown, the tailings mechanical mining and transportation road bottoming device of the present invention comprises a bearing pad 1, which is laid in the tailings reservoir to form a continuous road;

[0047] It also includes an extended fixing structure, which is used to enhance the stability of the bearing pad 1. The extended fixing structure includes a support anchor 2, a lap frame 21, a side baffle 24 and a reinforcing rib 25;

[0048] The support anchor rods 2 are anchored on the bank slope, and the support anchor rods 2 are installed vertically downward;

[0049] The lap frame 21 is slidably mounted on the support anchor rod 2. A sliding hole is provided on the lap frame 21. After the support anchor rod 2 is fixedly installed, the lap frame 21 is mounted on the support anchor rod 2 through the sliding hole. A mounting groove 22 is provided on the lap frame 21. The mounting groove 22 is provided on the side of the lap frame 21 away from the bank slope. One side of the bearing pad 1 is mounted in the mounting groove 22 by a connecting bolt 23.

[0050] The side baffle 24 is hingedly mounted on the side of the bearing pad 1 away from the lap frame 21. The side baffle 24 extends vertically into the tailings. During installation, the side baffle 24 and the bearing pad 1 are separated. According to the planned position of the temporary road in the reservoir, the side baffle 24 is first inserted into the tailings. Then, after the bearing pad 1 is installed, the side baffle 24 is hingedly connected to the bearing pad 1.

[0051] The bottom of the bearing pad 1 is fixedly mounted with evenly distributed reinforcing ribs 25 , and the reinforcing ribs 25 are vertically fixedly connected to the side baffles 24 .

[0052] When mechanically mining tailings that have been accumulated in the tailings pond for a long time, in order to reduce the probability of accidents such as tailings collapse and landslide and improve the safety of the mining process, a technical solution of mining in different areas and layers is adopted when mining tailings. With the help of the cooperation of excavators and transport vehicles, convenient mining of tailings is achieved. In this process, a bearing pad 1 is used in combination with an extended fixed structure to build a temporary road inside the tailings pond, and the temporary road inside the pond is connected with the road outside the pond, so as to enhance the convenience and safety of transporting the mined tailings.

[0053] Specifically, when building the temporary road in the reservoir, since the bearing capacity of the accumulated tailings itself is low and uneven, and the tailings are highly fluid when under pressure, when designing the temporary road in the reservoir, the temporary road in the reservoir is designed between the bank slope and the tailings reservoir, so that the temporary road in the reservoir can rely on the bank slope on one side. At the same time, when installing the supporting anchor rods 2, the staff use drilling equipment to fix the supporting anchor rods 2 on the bank slope, and assemble the lap frame 21 and the supporting anchor rods 2. Then, according to the planned position of the temporary road in the reservoir, the side baffles 24 are installed one by one, and finally the bearing pads 1 are laid one by one on the temporary road in the reservoir, and the lap frame 21, the bearing pad 1 and the side baffles 24 are connected one by one. Finally, after the vehicle driving test, the preliminary construction of the temporary road in the reservoir is completed. It should be noted that as the tailings in the tailings reservoir are gradually mined, the position of the temporary road in the reservoir needs to be adjusted according to the actual situation.

[0054] The present invention fixes the support anchor rod 2 on the bank slope, utilizes the stability of the bank slope, cooperates with the lap frame 21 to fix the position of the bearing pad 1, and cooperates with the supporting capacity of the bottom tailings to provide stable support for the bearing pad 1. At the same time, the presence of the side baffle 24 intercepts the tailings under the bearing pad 1, increases the difficulty of the tailings moving sideways, and thus makes the temporary road in the reservoir stable.

[0055] As a preferred embodiment of the present invention, it also includes a backfill reinforcement mechanism, which is installed below the bearing pad 1 and is used to backfill tailings below the bearing pad 1. The backfill reinforcement mechanism includes a lifting seat 3, a telescopic transmission cylinder 31, a telescopic rod 32 and a pull plate 34;

[0056] The lifting seat 3 is installed under the bearing pad 1. The lifting seat 3 is arranged in plural and arranged along the length direction of the bearing pad 1. The lifting seat 3 can be pre-installed under the bearing pad 1 and laid on the temporary road in the warehouse together with the bearing pad 1, or it can be laid on the temporary road in the warehouse alone. When laying, a groove is first dug on the temporary road in the warehouse according to the pre-installation position of the lifting seat 3 to facilitate burying the lifting seat 3 in the tailings. After the burial is completed, it is necessary to ensure that the upper surface of the lifting seat 3 is flush with the tailings plane;

[0057] The telescopic transmission cylinder 31 and the telescopic rod 32 are installed on the lifting seat 3. One end of the telescopic transmission cylinder 31 is fixedly installed in the lifting seat 3, and the other end abuts against the bearing pad 1. A support spring is installed inside the telescopic transmission cylinder 31. The telescopic transmission cylinder 31 is a conventional hydraulic telescopic cylinder, which consists of a fixed end and a movable end sealed and slidably installed inside the fixed end, and the support spring is installed in the inner cavity of the fixed end, which is used to push the movable end to move toward the outside of the fixed end. The bottom end of the telescopic transmission cylinder 31 is connected to the telescopic rod 32 through a conduit. The telescopic transmission cylinder 31 and the telescopic rod 32 are both filled with hydraulic oil, and hydraulic transmission is carried out between the two. A support spring is installed in the telescopic transmission cylinder 31. Therefore, when the telescopic transmission cylinder 31 is not subjected to external force, its length remains at the maximum value. At this time, the length of the telescopic rod 32 is the shortest. When the top end of the telescopic transmission cylinder 31 is pressurized, under the influence of pressure and hydraulic transmission effect, the length of the telescopic transmission cylinder 31 is shortened and the length of the telescopic rod 32 is increased.

[0058] The output end of the telescopic rod 32 is hingedly mounted with a pull plate 34, and a limit block 35 is installed on the output end of the telescopic rod 32. The limit block 35 is used to limit the rotation direction of the pull plate 34. The side baffle 24 is provided with a control slot 4, and the telescopic rod 32 extends through the control slot 4. After the load-bearing pad 1 is paved, the load-bearing pad 1 is pressed during the driving process of the vehicle, causing the load-bearing pad 1 to squeeze the telescopic transmission cylinder 31. After hydraulic transmission, the telescopic rod 32 extends. In this process, the output end of the telescopic rod 32 moves outward through the control slot 4, and in the process of movement, the pull plate 34 is hindered by the tailings and deflected toward the output end of the telescopic rod 32 until it fits on the output end of the telescopic rod 32. At this time, the pulling effect of the pull plate 34 on the tailings is minimal, and when the vehicle leaves the load-bearing pad 1, the telescopic transmission cylinder 31 recovers under the action of the support spring. The tailings are pushed downwards by the pull plate 34 when the telescopic rod 32 is extended, and the tailings are pushed downwards by the pull plate 34 when the telescopic rod 32 is extended.

[0059] The pulling plates 34 are provided in multiple groups, and the multiple groups of pulling plates 34 are evenly arranged along the width direction of the bearing pad 1 .

[0060] The bearing pad 1 is provided with a connecting hole 11, the diameter of the connecting hole 11 is larger than the diameter of the connecting bolt 23, the bearing pad 1 is connected to the connecting bolt 23 through the connecting hole 11, the depth of the mounting groove 22 is greater than the thickness of the bearing pad 1, and the inclination angle of the bearing pad 1 is less than 2 degrees in the initial state, and the lifting seat 3 is close to the lap frame 21. When the telescopic transmission cylinder 31 pushes the bearing pad 1 to rise, the bearing pad 1 is restricted by the side baffle 24 on one side, so that the bearing pad 1 is in an inclined state in the initial state. The inclined manner can increase the probability of the tailings on the bearing pad 1 sliding off, and the lifting and lowering movement of the bearing pad 1 before and after the vehicle passes, which further enhances the effect of the tailings falling off.

[0061] The telescopic rod 32 is flush with the top of the lifting seat 3, and the output end of the telescopic rod 32 is always supported by the control groove 4. When the bearing pad 1 is pressed by the vehicle, the bearing pad 1 moves downward and is finally supported by the telescopic rod 32 and the lifting seat 3, thereby effectively enhancing the supporting effect on the bearing pad 1.

[0062] As a preferred embodiment of the present invention, a reversing groove 41 and a limit groove 42 are provided at the output end of the telescopic rod 32, a reversing rod 45 is slidably installed in the reversing groove 41, and the reversing rod 45 is provided with evenly distributed telescopic grooves 46. The limit block 35 is elastically installed in the telescopic groove 46 by a spring. An adjustment groove 43 is provided at one end of the telescopic rod 32 close to the lifting seat 3, and a moving handle 44 is fixedly installed in the adjustment groove 43 of the reversing rod 45. The limit grooves 42 are designed in multiple numbers, and the limit grooves 42 are all located on both sides of the pull plate 34.

[0063] The adjusting slot 43 is a C-shaped structure, and the upper and lower sides of the limit block 35 are both designed with inclined surfaces. When the reversing rod 45 moves, it first rotates around the axis and then moves linearly along the axis.

[0064] During actual installation, the temporary road in the reservoir is initially built in the initial state. At this time, the tailings under the bearing pad 1 need to be lowered and moved sideways, so the limit block 35 is located on the side of the pulling plate 34 away from the lifting seat 3. During the telescopic movement of the telescopic rod 32, the pulling plate 34 continues to pull the sideways tailings back to the bottom of the bearing pad 1 to improve the supporting effect of the bearing pad 1. As the tailings in the tailings reservoir are mined layer by layer, the height of the tailings layer around the temporary road in the reservoir decreases. At this time, the height of the temporary road in the reservoir needs to be lowered, so the staff lifts up the bearing pad 1, and then manually holds the moving handle 44 to control the reversing rod 45 to perform a C-shaped movement along the adjusting groove 43. During the movement, the side of the limit block 35 contacts the limit groove 42. Under the action of the inclined surface, the limit block 35 moves into the telescopic groove 46. The rear reversing rod 45 performs linear motion along the axial direction of the telescopic rod 32, and finally rotates again, causing the telescopic slot 46 to align with the limit slot 42. At this time, the limit block 35 in the telescopic slot 46 enters the limit slot 42 on the other side of the pull plate 34, causing the pull plate 34 to switch from the state of pulling back the tailings to the state of pushing the tailings. In this state, when the telescopic rod 32 is extended, the pull plate 34 will push the tailings to move toward the outside of the control slot 4 under the support of the limit block 35, and when the telescopic rod 32 is shortened, the pull plate 34 rotates and fits toward the output end of the telescopic rod 32 under the obstruction of the tailings. At the same time, when the vehicle presses on the bearing pad 1, under the action of pressure, the tailings under the bearing pad 1 move sideways to the outside, so that the tailings under the bearing pad 1 continue to decrease, thereby causing the temporary road in the warehouse to descend.

[0065] It should be noted that in the present invention, the area of the pulling plate 34 is limited. During a single cycle of movement, the total amount of tailings pushed is preferably 1 / 20-1 / 15 of the total volume of the gap between the bearing pad 1 and the lifting seat 3 and the telescopic rod 32. Its function is only to cooperate with the side baffle 24 to slow down the lateral movement rate of the tailings below the bearing pad 1 or to accelerate the lateral movement rate of the tailings below the bearing pad 1.

[0066] As a preferred embodiment of the present invention, it further includes a side interception mechanism, which is installed on the side baffle 24. The side interception mechanism cooperates with the side baffle 24 to prevent the tailings from flowing out laterally from under the bearing pad 1. The side interception mechanism includes an extension rod 5 and a manifold 51.

[0067] The side baffle 24 is provided with a drilling hole, through which the extension rod 5 drills toward the bottom of the tailings;

[0068] The extension rod 5 is a hollow tubular structure with an open top. The bottom end of the extension rod 5 is provided with evenly arranged sockets 52. A multi-head tube 51 is installed inside the extension rod 5. The multi-head tube 51 is made of elastic material and extends to the outside of the extension rod 5 through the sockets 52.

[0069] The extension rods 5 are all externally connected to a water supply pipe, and the manifold 51 is provided with evenly distributed permeation micropores.

[0070] Since it is difficult to bury the side baffles 24, the depth of the side baffles 24 should not be too large. In order to enhance the interception effect of the tailings below the bearing pad 1, the present invention is also provided with a side interception mechanism, wherein the drilled holes opened on the side baffles 24 are used to guide the direction and position of the extension rod 5, so as to facilitate the insertion of the extension rod 5 into the deep tailings. After the extension rod 5 is inserted, the staff uses the pushing equipment to push the manifold 51 in the inner cavity of the extension rod 5 downward. The manifold 51 is made of elastic material, and the multiple ends at its bottom correspond to the sockets 52 one by one. As the top of the manifold 51 descends, its bottom end is gradually bent and inserted into the tailings under the guidance of the socket 52. , cooperate with the extension rod 5 to enhance the interception effect of tailings. At the same time, after the temporary road in the reservoir is built, the staff will insert the humidity sensor under the extension rod 5 with the help of drilling equipment, and then open the water supply pipe, causing water to flow into the extension rod 5 and the manifold 51, and penetrate into the tailings. As the water continues to penetrate, the tailings close to the manifold 51 will gradually become wet, and then the surface tension of the water will be used to adhere this part of the tailings, increasing the difficulty of the tailings under the bearing pad 1 to move sideways. When the water content of the tailings under the side baffle 24 is between 7% and 9%, the water supply is stopped. The water content should be checked and replenished at regular intervals.

[0071] like Figure 9 As shown, a method for paving the bottom of a tailings mechanical mining and transportation road comprises the following steps:

[0072] S1: Design a temporary road inside the reservoir with reference to the bank slope and the road outside the tailings reservoir, and level the tailings according to the designed temporary road inside the reservoir;

[0073] S2: Using drilling equipment, install support anchor rods 2 at equal intervals on one side of the temporary road in the reservoir close to the bank slope, and install side baffles 24 and side interception mechanisms on the other side of the temporary road in the reservoir;

[0074] S3: pre-connect the load-bearing pad 1 with the backfill reinforcement mechanism, and then arrange the lap frame 21 and the load-bearing pad 1 one by one on the temporary road in the depot;

[0075] S4: Control the water supply pipe to supply water to the extension rod 5 in small amounts and multiple times, and then connect the support anchor rod 2, the lap frame 21, the bearing pad 1, and the side baffle 24 one by one to complete the construction of the temporary road in the reservoir.
