Description

Technical Field

[0001] The invention relates to the technical field of open-pit mining, and in particular to an open-pit mining system. Background Art

[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 major links: mining and transportation. These two links are crucial to the entire process of ore from the surface or underground to the final destination. Under the existing technical framework, the mining stage relies on a variety of advanced mining equipment that can effectively dig ore out of the mine. Subsequently, the transportation stage requires the use of a series of transportation equipment, such as trucks, conveyor belts, etc., to transport the excavated ore to the processing site or storage area.

[0003] In the process of open-pit mining, mining and transportation are closely linked, and together they constitute the core process of ore mining. However, in actual operations, the terrain environment in the mining area is complex and changeable, which brings many challenges to mining and transportation operations. Due to the significant differences in geological conditions and topography in different mining areas, it is difficult to achieve efficient coordination of mining and transportation work within the same mining area or even between different locations. For example, in some steep or rugged mining areas, traditional transportation tools may not be able to reach the mining point smoothly; in other cases, there may be a mismatch between mining progress and transportation capacity, resulting in frequent situations where one party waits for the other. This lack of coordination in the operation mode seriously affects the overall operating efficiency and productivity of the open-pit mine. Summary of the invention

[0029] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0030] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0031] like Figure 1-Figure 4 As shown, the present invention provides an open-pit mining system, including a mining device, a transfer device 5, a pushing device 4, a transfer device 1, an output device, a transport track 2 and a carrier 3; the mining device includes a mining mechanism and a comprehensive excavation mechanism, the comprehensive excavation mechanism is arranged at the front end of the transfer device 1, and is used to mine mineral materials, and the feeding end of the transfer device 1 can collect the mineral materials mined by the comprehensive excavation mechanism; the mining mechanism is arranged at the side of the transfer device 1 for mining operations, the transfer device 5 is arranged along the length direction of the mining area, and the discharging end of the transfer device 5 is connected to the transfer device 1, and the mining material is collected by the comprehensive excavation mechanism. The ore mined by the excavation mechanism is transferred to the transfer device 1; the pushing device 4 is corresponding to the transfer device 5, and the pushing device 4 includes a pushing member 402, the telescopic end of the pushing member 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 annular, and the carrier 3 circulates 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 carrier 3.

[0032] Compared with the prior art, the transportation system provided by the present invention has the following advantages:

[0033] The open-pit mining system provided by the present invention can realize the mining of the mineral material area through the mining mechanism and the comprehensive mining mechanism. Taking the mining face close to a rectangle 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 of the mine for mining. The mined ore can be transported from the transfer device 1 to the output device. Therefore, the open-pit mining system provided by this application needs to first determine the position of the output device, that is, according to different mine terrains, select a suitable position to arrange the output device, and then connect the transfer device 1 with the feed port of the output device. Since the comprehensive excavation 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 comprehensive excavation mechanism can directly perform front excavation at the corresponding position, and the mined ore can directly pass through the transfer device 1 into the output device to realize the mining and output of the 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 up a mining mechanism on the side of the transfer device 1, the mineral materials on the side of the comprehensive excavation mechanism can be mined synchronously, thereby greatly improving the working efficiency.

[0036] Correspondingly, the transfer device 5 in the present application is arranged corresponding to the mining mechanism, so as to be able to carry the mineral materials mined by the mining mechanism.

[0037] Preferably, the mining mechanism in the present application is a large-height coal mining machine, which can collect the mined ore while mining, and discharge it to the transfer device 5 from the discharge port. Accordingly, the transfer device 5 in the present application includes a base and a conveyor belt, the conveyor belt can carry and transport the ore, and the base can carry the conveyor belt, providing a mounting mechanism for the transmission belt and the corresponding power mechanism.

[0038] Furthermore, the base in the present application is also formed with a retaining wall, and one end of the above-mentioned pushing member 402 is rotatably connected to the retaining wall, so that the movement of the entire transfer device 5 can be achieved by pushing the retaining wall.

[0039] It can be understood that as the mining operation continues, after the mining of the ore layer at the current position is completed, the mining mechanism moves forward to continue to fit the mining surface for mining operations. Accordingly, the pushing device 4 is used to push 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 the present application includes a plurality of transfer modules, which are connected in series to form a flexible scraper conveyor, and the pushing device 4 is arranged in a one-to-one correspondence with the transfer modules.

[0041] Since the transfer device 5 in the present application is a flexible scraper conveyor, by means of the pushing devices 4 arranged one by one in correspondence with the transfer modules, the pushing devices 4 at the corresponding positions can be selected for pushing operations according to the specific mining conditions and terrain environment conditions, thereby enabling the overall transfer device 5 to better adapt to the mining operations of the mining mechanism.

[0042] Since the discharge end of the transfer device 5 in the present application is connected to the transfer device 1, it can be understood that since the transfer device 5 in the present application is a scraper conveyor, and the transfer device 1 is a self-propelled bridge transfer machine, both have corresponding transmission structures. Therefore, as long as the discharge end of the scraper conveyor can correspond to the transmission structure of the self-propelled bridge transfer machine, the transfer of mineral materials can be completed.

[0043] When the mineral materials fall onto the transfer machine, they can be transported to the output device in a unified manner.

[0044] It should be noted here that the output device in the present application includes a belt conveyor and a drop tower. The feed end of the belt conveyor is connected to the discharge end of the transfer machine, so that it can further carry the mineral material and transport the mineral material to the drop tower. The drop tower corresponds to the first position of the transport track 2. The drop tower in the present 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 drop port is formed in the tower body. The sealing door covers the drop port. When the mineral material needs to be released, the sealing door is opened.

[0045] Correspondingly, an avoidance bridge tunnel is formed at the bottom of the tower body for laying the transport track 2 and allowing the transport vehicle 3 to pass through. The first position of the above-mentioned transport track 2 corresponds to the avoidance bridge tunnel and is located directly below the drop port. When the transport vehicle 3 reaches the first position, it stops, the sealing door opens, and the ore falls into the transport vehicle 3.

[0046] When the carrier 3 is filled with ore, the sealing door is closed, and the carrier 3 moves forward one position. The next carrier 3 corresponds to the material drop port, the sealing door is opened, and loading continues. The above actions are repeated to realize the assembly line operation from mining to loading of ore.

[0047] It needs to be further explained here that, since the mining area is usually located at a low place and the unloading yard is located at a high place, a supporting bridge can be arranged in the mine, so as to provide a foundation for the laying of the transport track 2, so that the transport track 2 can cover the mining area and the unloading yard area, and then the carrier vehicle 3 can receive the ore at a low place and move along the transport track 2 to the high unloading yard for unloading in a cyclic operation.

[0048] In an optional embodiment, the pushing device 4 in the present application also 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 body 401 can be positioned by means of a positioning mechanism which is provided on the positioning body 401 and extends in the vertical direction and whose telescopic end can be drilled into or rotated out of the ground, while the forward movement and retraction of the transfer module can be achieved by means of the pushing member 402 .

[0050] In actual operation, the positioning mechanism is first used to drill into the ground to achieve the combination of the positioning body 401 and the ground, thereby ensuring the stability of the positioning body 401. Then, the transfer module is pushed by extending the pushing member 402. When pushed into place, the positioning mechanism is rotated out of the ground, and the pushing member 402 is contracted, thereby pulling the positioning body 401 forward. After moving into place, the positioning mechanism drills into the ground again to complete a pushing action.

[0051] In an optional embodiment, the positioning mechanism in the present application includes a lifting assembly and a positioning assembly; the positioning assembly includes a first driving member 405 and a positioning member, the output end of the first driving member 405 is connected to one end of the positioning member, and the other end of the positioning member can be drilled into or rotated out of the ground; one end of the lifting assembly is connected to the positioning body 401, and the other end is connected to the first driving member 405, and the lifting assembly can be extended and retracted in the vertical direction to drive the first driving member 405 to move in the vertical direction.

[0052] The lifting assembly in the present application includes a lifting drive, and both the lifting drive and the pushing member 402 use oil cylinders, which can provide more stable thrust and pressure.

[0053] Furthermore, the lifting assembly in the present application also includes a connecting square box 6, through which the connection between the lifting drive and the first driving member 405 can be realized, that is, one end of the lifting drive in the present application is connected to the positioning body 401, and the other end is connected to one end of the connecting square box 6, and the other end of the connecting square box 6 is connected to the first driving member 405, so that when the lifting drive is extended and retracted, the purpose of driving the first driving member 405 to reciprocate in the vertical direction can be achieved.

[0054] Preferably, in the present application, a guide column can be further provided at a position on the positioning body 401 corresponding to the connecting square box 6, and the connecting square box 6 is sleeved on the guide column and can slide along the guide column, thereby ensuring the stability of the movement of the positioning mechanism.

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

[0056] It can be understood that the first driving component 405 in the present application is a driving motor. During the actual drilling process, the driving motor starts to drive the drill rod 403 to rotate, thereby driving the drill bit 404 to rotate. At the same time, the lifting drive contracts, driving the connecting square box 6 to move downward, thereby driving the driving motor to move downward, and then realizing the drill bit 404 drilling into the underground.

[0057] In an optional embodiment, the transfer device 1 in the present application is arranged perpendicular to the transfer device 5, and the transfer device 1 is a self-propelled bridge-type transfer machine, and the comprehensive excavation mechanism is a comprehensive excavation machine.

[0058] In an optional embodiment, the open-pit mining system provided in the present application further includes a supporting device, which is relatively arranged on both sides of the comprehensive excavation mechanism to support the area formed after the comprehensive excavation mechanism is mined.

[0059] The support device in this application is a sliding temporary support device with the function of automatic forward movement. When the comprehensive excavation mechanism completes the mining operation of one working face and moves forward, the sliding temporary support device follows the comprehensive excavation mechanism forward to support the previous working face, thereby ensuring the safety of the comprehensive excavation mechanism when mining the next working face.

[0060] In an optional embodiment, the transport track 2 includes a guide track 201, a supporting track 202 and a unloading track 203, the width of the supporting track 202 is greater than the width of the guide track 201, the unloading track 203 is arc-shaped, corresponding to the supporting track 202, and the end point of the supporting track 202 is docked with the starting point of the unloading track 203, and the starting point of the supporting track 202 is docked with the end point of the unloading track 203; there are multiple driving mechanisms, which are arranged at intervals on the guide track 201, and are used to drive the carrier 3; the carrier 3 includes a box body 301 and a carrying mechanism, the box body 301 is placed on the carrying mechanism, and the box body 301 is rotatably connected to one end of the carrying mechanism, the width of the box body 301 is compatible with the supporting track 202, and the width of the carrying mechanism is smaller than the width of the supporting track 202.

[0061] The present application can carry the carrier 3 via the guide rail 201 , and can drive the carrier 3 via a plurality of driving mechanisms arranged along the extension direction of the guide rail 201 , that is, the movement of the carrier 3 on the guide rail 201 can be achieved via the driving mechanisms.

[0062] Since the present application also includes a supporting rail 202 and a unloading rail 203, the supporting rail 202 and the unloading rail 203 are arranged correspondingly, the unloading rail 203 is arc-shaped and is located below the supporting rail 202, and one end of the unloading rail 203 is connected to the end point of the guide rail 201, and the other end is connected to the starting point of the guide rail 201. The carrier 3 in the present application includes a box body 301 and a carrying mechanism, the box body 301 is placed on the carrying mechanism, and one end of the box body 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 carrier 3 reaches the end point of the guide rail 201, the carrying mechanism can continue to move along the unloading rail 203.

[0063] Since the interval between the support rails 202 in the present application is greater than the interval between the discharge rails 203, and the interval between the support rails 202 is adapted to the width of the box 301, as the carrier 3 moves forward, the box 301 moves forward on the support rails 202, and since the width of the bearing mechanism in the present application is smaller than the width of the box 301, the end of the bearing mechanism away from the rotational connection with the box 301 will gradually separate from the box 301 under the action of gravity. That is, the box 301 moves along the support rails 202, and the bearing mechanism moves along the discharge rails 203. In this process, since the bottom of the box 301 is opened, the materials will be directly discharged.

[0064] It can be understood that, since the supporting mechanism in the present application acts as the bottom of the box 301, there is no obstruction to the material after opening, so that the material can be completely poured out, and the unloading process is faster, thereby improving the overall transportation efficiency.

[0065] During the unloading process, the center of gravity of the entire transport vehicle 3 will not shift to the left or right sides, so the transport vehicle 3 can be ensured to run stably on the transport track 2, thereby improving the stability of the entire transport system.

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

[0067] In an optional embodiment, the supporting mechanism in the present application includes a supporting plate 302, a pin row 303 and a track wheel 304; the track wheel 304 and the pin row 303 are both connected to the side of the supporting plate 302 facing away from the box body 301, and the track wheel 304 is arranged corresponding to the guide track 201; the driving mechanism includes a second driving member and a transmission wheel, the output end of the second driving member is connected to the transmission wheel, and the pin row 303 is meshed with the transmission wheel.

[0068] The second driving member in the present application is a driving motor, and since the carrier 3 needs to carry mineral materials and also needs to climb a slope, the second driving member in the present application can be set corresponding to the two guide rails 201, that is, one transmission wheel corresponds to two second driving members, so as to provide a more stable power output. It can be understood that the output shaft of the motor in the present application can be further connected to the transmission shaft, and the transmission shaft is connected to the transmission wheel to realize the rotation of the transmission wheel.

[0069] The transmission wheel in the present application may be a friction wheel, which contacts the bottom of the carrier plate 302, so that the vehicle 3 can be moved under the action of friction when rotating.

[0070] However, since the overall guide track 201 needs to be arranged according to the terrain of the specific open-pit coal mine site, there will be high points and low points. Accordingly, the carrier vehicle 3 needs to climb and lower the slope, and the use of only friction wheels may easily cause the carrier vehicle 3 to be unable to climb the slope or stall when lowering the slope. Therefore, preferably, the transmission wheel in the present application is a gear, so that the stable movement of the carrier vehicle 3 is achieved through the engagement of the pin row 303 with the gear.

[0071] In an optional embodiment, the transport track 2 is in a U-shape, there are multiple transport vehicles 3, and the multiple transport vehicles 3 are connected end to end and circulate on the transport track 2.

[0072] In the present application, the train formed by multiple transport vehicles 3 can completely cover the transport track 2, and the arrangement number of the above-mentioned driving mechanisms can also correspond to the setting of the transport vehicles 3, so that all the transport vehicles 3 included in the train can be synchronously started to achieve synchronous advancement, which can not only increase the carrying capacity to a certain extent, but also achieve that the transport vehicle 3 only moves one vehicle distance each time.

[0073] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
