Description

Technical Field

[0001] This invention relates to the field of open-pit mining technology, and more specifically, to an open-pit mining system. Background Technology

[0002] With the development of open-pit mining technology, open-pit mining has become an important part of modern mining. Open-pit mining mainly includes two stages: extraction and transportation. These two stages are crucial to the entire process of ore moving from the surface or underground to its final destination. Under the current technological framework, the extraction stage relies on various advanced extraction equipment, which can effectively excavate ore from the mine. Subsequently, the transportation stage requires a series of transport equipment, such as trucks and conveyor belts, to transport the excavated ore to processing sites or storage areas.

[0003] In open-pit mining, extraction and transportation are closely linked, forming the core process of ore extraction. However, in practice, the complex and varied terrain of mining areas presents numerous challenges to both extraction and transportation operations. Significant differences in geological conditions and topography across different mining areas make efficient coordination of extraction and transportation work difficult, even within the same mining area and between different locations. For example, in some steep or rugged areas, traditional transportation methods may not be able to reach the extraction point smoothly; in other cases, there may be a mismatch between extraction progress and transportation capacity, leading to frequent instances of one side waiting for the other. This lack of coordination severely impacts the overall operational efficiency and productivity of open-pit mines. Summary of the Invention

[0007] In an optional embodiment, the transfer device includes multiple transfer modules, which are connected in series to form a flexible scraper conveyor, and the pushing device is configured in a one-to-one correspondence with each of the transfer modules.

[0010] In an optional embodiment, the positioning component includes a drill rod and a drill bit, with one end of the drill rod connected to the output end of the first driving component and the other end connected to the drill bit.

[0012] In an optional embodiment, a support device is also included, which is disposed opposite to each other on both sides of the tunneling machine to support the area formed after the tunneling machine has been mining.

[0013] In an optional embodiment, the transport track includes a guide track, a support track, and an unloading track. The width of the support track is greater than the width of the guide track. The unloading track is arc-shaped and corresponding to the support track. The end point of the support track aligns with the start point of the unloading track, and the start point of the support track aligns with the end point of the unloading track. Multiple drive mechanisms are spaced apart on the guide track to drive the transport vehicle. The transport vehicle includes a box and a carrying mechanism.

[0029] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0030] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0031] like Figures 1-4 As shown, this invention provides an open-pit mining system, including a mining device, a transfer device 5, a pushing device 4, a transshipment device 1, an output device, a transport track 2, and a transport vehicle 3. The mining device includes a mining mechanism and a tunneling mechanism. The tunneling mechanism is located at the front end of the transfer device 1 and is used to mine ore. The feed end of the transfer device 1 can collect the ore mined by the tunneling mechanism. The mining mechanism is located on the side of the transfer device 1 for mining operations. The transfer device 5 is arranged along the length of the mining area, and the discharge end of the transfer device 5 is connected to the transfer device 1 to transfer the mined ore. The ore mined by the excavator is transferred to the transfer device 1; the pushing device 4 is correspondingly set to the transfer device 5, and the pushing device 4 includes a pushing component 402. The telescopic end of the pushing component 402 is connected to the transfer device 5 to push the transfer device 5; the discharge end of the transfer device 1 is connected to the feed end of the output device. The transport track 2 is circular, and the transport vehicle 3 runs cyclically on the transport track 2. The discharge end of the output device corresponds to the first position of the transport track 2 and is located above the transport track 2, so that the ore is discharged from the discharge end of the output device and enters the transport vehicle 3.

[0032] Compared with existing technologies, the transportation system provided by this invention has the following advantages:

[0033] The open-pit mining system provided by this invention can mine ore areas through a mining mechanism and a tunneling mechanism, taking a mining face that is nearly rectangular as an example:

[0034] Since the mining mechanism is installed at the front end of the transfer device 1, it can directly face the mining face for mining. The mined ore can be transported from the transfer device 1 to the output device. Therefore, the open-pit mining system provided in this application needs to first determine the location of the output device, that is, select a suitable location to arrange the output device according to different mine terrains, and then connect the transfer device 1 to the feed inlet of the output device. Since the tunneling mechanism in this application is located at the front end of the transfer device 1, after the transfer device 1 is arranged corresponding to the output device, the tunneling mechanism can directly perform forward excavation at the corresponding location, and the mined ore can directly enter the output device through the transfer device 1, realizing the mining and output of ore.

[0035] It is understandable that since the appropriate installation position of the output device in the mine may not accurately correspond to the middle area of ​​the rectangular mining face, by further setting a mining mechanism on the side of the transfer device 1, the ore at the side position of the tunneling mechanism can be mined simultaneously, thereby greatly improving the operating efficiency.

[0036] Accordingly, the transfer device 5 in this application is provided for the mining mechanism, so as to be able to carry the ore mined by the mining mechanism.

[0037] Preferably, the mining mechanism in this application is a high-extraction coal mining machine, which can collect the mined ore while mining and discharge it from the outlet to the transfer device 5. Accordingly, the transfer device 5 in this application includes a base and a conveyor belt. The conveyor belt can carry and transport the ore, while the base can support the conveyor belt and provide an installation mechanism for the drive belt and the corresponding power mechanism.

[0038] Furthermore, the base in this application also forms a retaining wall, and one end of the aforementioned pushing member 402 is rotatably connected to the retaining wall, thereby enabling the overall transfer device 5 to be moved by pushing the retaining wall.

[0039] Understandably, as mining operations continue, once the ore layer at the previous location is mined, the mining mechanism moves forward to continue mining operations close to the mining face. Correspondingly, the pushing device 4 pushes the transfer device 5 forward, so that it can continue to correspond to the discharge port of the mining mechanism, thereby realizing the carrying and transfer of materials.

[0040] In an optional embodiment, the transfer device 5 in this application includes multiple transfer modules, which are connected in series to form a flexible scraper conveyor, and the pushing device 4 is set in a one-to-one correspondence with the transfer modules.

[0041] Since the transfer device 5 in this application is a flexible scraper conveyor, the pusher 4, which is set one-to-one with the transfer module, can be selected to perform the pusher operation according to the specific mining conditions and terrain environment, so that the overall transfer device 5 can better adapt to the mining operation of the mining organization.

[0042] Since the discharge end of the transfer device 5 in this application is connected to the transfer device 1, it can be understood that since the transfer device 5 in this application is a scraper conveyor and the transfer device 1 is a self-moving bridge transfer machine, both have corresponding conveying structures. Therefore, as long as the discharge end of the scraper conveyor is aligned with the conveying structure of the self-moving bridge transfer machine, the transfer of ore can be completed.

[0043] Once the ore falls onto the transfer machine, it can be transported to the output device in a unified manner.

[0044] It should be noted that the output device in this application includes a belt conveyor and a discharge tower. The feed end of the belt conveyor is connected to the discharge end of the transfer machine, so as to further carry the ore and transport it to the discharge tower. The discharge tower corresponds to the first position of the transport track 2. The discharge tower in this application mainly includes a tower body and a sealing door. The top of the tower body is connected to the discharge end of the output device. A discharge port is formed inside the tower body. The sealing door covers the discharge port. When it is necessary to release the ore, the sealing door is opened.

[0045] Correspondingly, a clearance arch is formed at the bottom of the tower body to enable the laying of transport track 2 and the passage of transport vehicle 3. The first position of the transport track 2 is the corresponding clearance arch and is located directly below the material drop port. When transport vehicle 3 reaches the first position, it stops, the gate is opened, and the ore falls into transport vehicle 3.

[0046] Once the transport vehicle 3 is full of ore, the gate is closed. The transport vehicle 3 moves forward one position, and the gate of the next transport vehicle 3 corresponding to the material discharge port is opened to continue loading. The above actions are repeated to realize the assembly line operation of ore from mining to loading.

[0047] It should be further explained here that, since the mining area is usually located at a low level and the unloading site is located at a high level, a support bridge can be set up in the mine to provide a foundation for the laying of the transport track 2. This allows the transport track 2 to cover both the mining area and the unloading site area, thereby enabling the transport vehicle 3 to receive the ore at a low level and travel along the transport track 2 to the high unloading site for unloading in a cyclical operation.

[0048] In an optional embodiment, the pushing device 4 in this application further includes a positioning body 401 and a positioning mechanism; the positioning mechanism is connected to the positioning body 401 and extends in the vertical direction, the telescopic end of the positioning mechanism can drill into or rotate out of the ground, the pushing member 402 extends in the horizontal direction, and one end of the pushing member 402 is rotatably connected to the positioning body 401, and the other end is rotatably connected to the transfer module.

[0049] The positioning mechanism, which extends vertically on the positioning body 401 and whose telescopic end can drill into or rotate out of the ground, can be used to position the positioning body 401. The forward and backward movement of the transfer module can be achieved through the pushing component 402.

[0050] In actual operation, the positioning mechanism first drills into the ground to connect the positioning body 401 with the ground, thus ensuring the stability of the positioning body 401. Then, the transfer module is moved by extending the pushing component 402. After being moved into place, the positioning mechanism rotates out of the ground, the pushing component 402 retracts, thereby pulling the positioning body 401 forward. After it moves into place, the positioning mechanism drills into the ground again to complete one pushing operation.

[0051] In an optional embodiment, the positioning mechanism of this application includes a lifting component and a positioning component; the positioning component includes a first driving component 405 and a positioning component, the output end of the first driving component 405 is connected to one end of the positioning component, and the other end of the positioning component can drill into or rotate out of the ground; one end of the lifting component is connected to the positioning body 401, and the other end is connected to the first driving component 405, and the lifting component can extend and retract in the vertical direction to drive the first driving component 405 to move in the vertical direction.

[0052] The lifting assembly in this application includes a lifting drive, and both the lifting drive and the pushing component 402 are hydraulic cylinders, which can provide more stable thrust and pressure.

[0053] Furthermore, the lifting assembly in this application also includes a connecting box 6, which enables the connection between the lifting drive and the first driving member 405. That is, one end of the lifting drive is connected to the positioning body 401, and the other end is connected to one end of the connecting box 6. The other end of the connecting box 6 is connected to the first driving member 405, thereby enabling the first driving member 405 to reciprocate in the vertical direction when the lifting drive extends or retracts.

[0054] Preferably, in this application, a guide post can also be provided on the positioning body 401 at the position corresponding to the connecting box 6. The connecting box 6 is sleeved on the guide post and can slide along the guide post, thereby ensuring the stability of the positioning mechanism's movement.

[0055] In an optional embodiment, the positioning component includes a drill rod 403 and a drill bit 404, with one end of the drill rod 403 connected to the output end of the first drive component 405 and the other end connected to the drill bit 404.

[0056] It is understood that the first driving component 405 in this application is a drive motor. During the actual drilling process, the drive motor starts and drives the drill rod 403 to rotate, thereby driving the drill bit 404 to rotate. At the same time, the lifting drive retracts, driving the connecting box 6 to move down, thereby driving the drive motor to move down, thus realizing the drilling of the drill bit 404 into the ground.

[0057] In an optional embodiment, the transfer device 1 in this application is arranged perpendicular to the transfer device 5, and the transfer device 1 is a self-moving bridge transfer machine, while the tunneling mechanism is a tunneling machine.

[0058] In an optional embodiment, the open-pit mining system provided in this application further includes a support device, which is arranged opposite to each other on both sides of the tunneling machine to support the area formed after the tunneling machine has finished mining.

[0059] The support device in this application is a sliding temporary support device with an automatic forward movement function. After the tunneling machine completes the mining operation of one working face and moves forward, the sliding temporary support device moves forward with the tunneling machine to support the previous working face and ensure the safety of the tunneling machine when mining the next working face.

[0060] In an optional embodiment, the transport track 2 includes a guide track 201, a support track 202, and an unloading track 203. The width of the support track 202 is greater than the width of the guide track 201. The unloading track 203 is arc-shaped and is set corresponding to the support track 202. The end point of the support track 202 is connected to the starting point of the unloading track 203, and the starting point of the support track 202 is connected to the end point of the unloading track 203. There are multiple driving mechanisms, which are arranged at intervals on the guide track 201 to drive the transport vehicle 3. The transport vehicle 3 includes a box 301 and a carrying mechanism. The box 301 is placed on the carrying mechanism, and the box 301 is rotatably connected to one end of the carrying mechanism. The width of the box 301 is adapted to the support track 202, and the width of the carrying mechanism is smaller than the width of the support track 202.

[0061] This application enables the carrier vehicle 3 to be carried by the guide rail 201, and the carrier vehicle 3 can be driven by multiple drive mechanisms arranged along the extension direction of the guide rail 201, that is, the movement of the carrier vehicle 3 on the guide rail 201 can be realized by the drive mechanisms.

[0062] Since this application also includes a support track 202 and an unloading track 203, the support track 202 and the unloading track 203 are correspondingly arranged. The unloading track 203 is arc-shaped and located below the support track 202. One end of the unloading track 203 is connected to the end point of the guide track 201, and the other end is connected to the starting point of the guide track 201. The transport vehicle 3 in this application includes a box 301 and a carrying mechanism. The box 301 is placed on the carrying mechanism, and one end of the box 301 is rotatably connected to one end of the carrying mechanism, and the other end is in contact with the carrying mechanism. Therefore, when the transport vehicle 3 reaches the end point of the guide track 201, the carrying mechanism can continue to move along the unloading track 203.

[0063] Because the spacing between the supporting rails 202 in this application is greater than the spacing between the unloading rails 203, and the spacing between the supporting rails 202 is adapted to the width of the container 301, as the transport vehicle 3 moves forward, the container 301 moves forward on the supporting rails 202. Since the width of the bearing mechanism in this application is smaller than the width of the container 301, the end of the bearing mechanism furthest from the rotatably connected container 301 will gradually separate from the container 301 under the action of gravity. That is, the container 301 moves along the supporting rails 202, and the bearing mechanism moves along the unloading rails 203. During this process, because the bottom of the container 301 is opened, the material is directly unloaded.

[0064] It is understandable that, since the load-bearing mechanism in this application acts as the bottom of the container 301, there is no obstruction to the material after it is opened, thus enabling the complete dumping of the material. Furthermore, the unloading process is faster, improving the overall transportation efficiency.

[0065] During the unloading process, the center of gravity of the overall transport vehicle 3 will not shift to the left or right, thus ensuring that the transport vehicle 3 runs stably on the transport track 2, thereby improving the stability of the overall transport system.

[0066] It should be noted that the unloading track 203 in this application corresponds to the unloading yard setting mentioned above, that is, it is located above the unloading yard. So when the transport vehicle 3 passes through the unloading track 203, it can dump all the ore it is carrying into the unloading yard, thereby completing the overall operation process of open-pit mining.

[0067] In an optional embodiment, the bearing mechanism in this application includes a bearing plate 302, a pin array 303, and a track wheel 304; the track wheel 304 and the pin array 303 are both connected to the side of the bearing plate 302 away from the housing 301, and the track wheel 304 is provided corresponding to the guide rail 201; the driving mechanism includes a second driving component and a transmission wheel, the output end of the second driving component is connected to the transmission wheel, and the pin array 303 meshes with the transmission wheel.

[0068] The second driving component in this application is a drive motor. Since the transport vehicle 3 needs to carry ore and climb slopes, the second driving component can be correspondingly arranged with the two guide rails 201, meaning one transmission wheel corresponds to two second driving components, thus providing a more stable power output. It is understood that the output shaft of the motor in this application can be further connected to a transmission shaft, which connects to the transmission wheel to achieve rotation of the transmission wheel.

[0069] The transmission wheel in this application can be a friction wheel. The friction wheel contacts the bottom of the support plate 302, so that the vehicle 3 can move under the action of friction when rotating.

[0070] However, since the overall guide track 201 needs to be arranged according to the specific terrain of the open-pit coal mine, there will be high points and low points. Accordingly, the transport vehicle 3 needs to climb and descend slopes. However, using only friction wheels can easily cause the transport vehicle 3 to be unable to climb or to stall when descending slopes. Therefore, preferably, the transmission wheel in this application is a gear, so that the stable movement of the transport vehicle 3 can be achieved through the meshing of the pin 303 with the gear.

[0071] In an optional implementation, the transport track 2 is shaped like a square, and there are multiple transport vehicles 3, which are connected end to end and travel in a loop on the transport track 2.

[0072] In this application, the train formation formed by multiple carrier vehicles 3 can completely cover the transport track 2, and the number of drive mechanisms can also be set according to the number of carrier vehicles 3. Thus, by activating all the drive mechanisms simultaneously, all the carrier vehicles 3 in the train formation can move forward synchronously, which can increase the carrying capacity to a certain extent and also ensure that each movement of the carrier vehicle 3 only travels one car length.

[0073] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
