Description

Technical Field

[0001] This invention belongs to the field of automatic ore extraction systems, and specifically relates to an ore extraction management system for ore passes and its operation method. Background Technology

[0002] After ore is mined, in order to quickly transport the ore from the stope to the ore bin or subsequent processing areas, shovels and haulage equipment are often used to transport the ore from the stope to the ore pass for ore chuting. The ore is then discharged through the ore extraction equipment at the bottom of the ore pass and transferred to transport equipment. However, with existing technology, to increase mining efficiency, multiple work teams and ore passes are set up within the mine for ore extraction based on the stope. The loading and unloading processes of each work team cannot be tracked, and calculations can only be done through manual reporting. Errors such as unloading into the wrong ore pass, loading into the wrong stope, or misrecording the vehicle type or number will lead to data errors during subsequent settlement, making it difficult for each work team to verify and settle accounts, resulting in inconvenience in production management. Furthermore, with existing technology, the driving, loading, and unloading of shovels and haulage equipment still require manual control on the vehicle, resulting in low automation. Since the stope is mostly located inside the mine shaft, manual work inside poses certain risks and is quite inconvenient. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] To overcome the shortcomings of existing technologies, a ore pass management system and its operation method are proposed. This system addresses the problem that, in order to increase mining efficiency, multiple construction teams and ore passes are set up in the mine according to the stope for ore extraction. However, the loading and unloading processes of each construction team cannot be tracked, and calculations can only be performed through manual reporting. If the wrong ore pass is unloaded, the wrong ore block is entered during loading, or the vehicle type or number is recorded incorrectly, it will lead to errors in the subsequent settlement data, making it inconvenient for each construction team to verify and settle accounts, and causing inconvenience to production management.

[0005] Secondly, to address the issue that when using existing technologies, the loading and unloading of ore by shovels and transport equipment requires manual control on the vehicle, resulting in low automation. Furthermore, since mining areas are mostly located inside mine shafts, manual work inside poses certain risks and is quite inconvenient.

[0006] (II) Technical Solution

[0007] This invention is achieved through the following technical solution: This invention proposes a ore pass management system and its operation method, the structure of which includes a shovel and conveying equipment, a minehouse, a track scale, an unmanned aerial vehicle (UAV), ore passing equipment, and an ore pass. The minehouse is used for ore mining and storage, the shovel and conveying equipment is used to transport minerals from the minehouse to the ore pass, the bottom of the ore pass is connected to the ore passing equipment, the UAV is used to receive the ore from the ore passing equipment, and the track scale is used for weighing the UAV;

[0008] It also includes a first identification card, a base station, a host, a second identification card, and sensors. Each feed inlet of the ore pass is equipped with a corresponding second identification card, and each ore pass is equipped with a first identification card. The base station and sensors are mounted on the shovel and conveyor equipment. The host is connected to the base station, track scale, unmanned vehicle, ore discharge equipment, and sensor network. The base station is used to identify the information of the first and second identification cards and transmit it to the host. The first identification card is used to identify ore pass information, the second identification card is used to identify ore pass information, the base station is used to identify and locate the shovel and conveyor equipment, and the sensors are used to detect the ore unloading action of the shovel and conveyor equipment.

[0009] Furthermore, the base station is a UWB base station.

[0010] Furthermore, the sensor is a pressure sensor or a limit switch.

[0011] Furthermore, when the sensor is a pressure sensor, the sensor is mounted on the pump rod of the unloading bucket of the shovel and conveying equipment, and the change in pressure of the pump rod of the unloading bucket of the shovel and conveying equipment is used to determine whether a loading or unloading action has been performed.

[0012] Furthermore, when the sensor is a limit switch, the sensor is mounted on the mechanical arm of the unloading bucket of the shovel and conveying equipment, and the movement of the mechanical arm of the unloading bucket of the shovel and conveying equipment is used to determine whether a loading or unloading action has been performed.

[0013] Furthermore, the shovel and conveyor equipment may also be equipped with a voice device.

[0014] Furthermore, the base station and the first and second identification cards are interchangeably mounted, the mine and the ore pass are equipped with the base station, and the shovel and transport equipment is equipped with the identification card.

[0015] The present invention also provides an operation method for a ore pass management system, the method being as follows:

[0016] 1. Divide the work into more than one construction team, and allocate the chute to each construction team. Identify the base station through the host computer and register the shovel and transport equipment information corresponding to each base station in the host computer.

[0017] 2. During ore extraction, after the shovel and transport equipment enters the mine, the base station installed on the shovel and transport equipment will identify the first identification card of the mine and upload it to the host. After receiving the identification information of the first identification card, the host will enter the ore loading determination procedure. When the sensor returns data that matches the ore loading action, the host will determine that the shovel and transport equipment equipped with the base station has loaded ore and record it. When the sensor does not return data that matches the ore loading action, the host will determine that the shovel and transport equipment equipped with the base station is just passing by.

[0018] 3. When unloading ore into the pass, the base station installed on the shovel and conveying equipment will first identify the second identification card of the pass and then transmit it to the host. After receiving the identification information of the second identification card, the host will enter the ore unloading determination procedure. When the sensor returns data that matches the ore unloading action, the host will determine that the shovel and conveying equipment equipped with the base station has unloaded ore and record it. When the sensor does not return data that matches the ore unloading action, the host will determine that the shovel and conveying equipment equipped with the base station is passing by.

[0019] 4. After the host receives a notification from the base station of the corresponding pass that ore is being unloaded, it controls the unmanned vehicle to travel to the ore discharge equipment of the corresponding pass, then controls the ore discharge equipment to discharge ore onto the unmanned vehicle, and then controls the unmanned vehicle to travel to the track scale for weighing and recording before unloading the ore.

[0020] 5. The host calculates and compares the ore output according to the settings at fixed times or times. During the calculation, the full load weight is obtained by weighing the unmanned vehicle after each shovel and conveyor equipment is fully loaded. Then, the full load weight of each shovel and conveyor equipment is divided by the full load capacity of each shovel and conveyor equipment to obtain the weight per cubic meter coefficient of each shovel and conveyor equipment. The ore output is obtained by multiplying the number of ore outputs of each shovel and conveyor equipment by the recorded rated capacity and the weight per cubic meter coefficient. The total ore output of each group is obtained by summing the total ore output of each shovel and conveyor equipment. Finally, the total ore output is compared with the total ore output weighed by the rail scale.

[0021] 6. When the reported ore output of each group is within ±5% of the weighed ore output, it is determined that the reported ore output is accurate. When the reported ore output of each group exceeds ±5% of the weighed ore output, it is determined that the reported ore output is inaccurate, and manual verification is notified.

[0022] Furthermore, the host can record the amount of ore in the ore pass after multiple unloading operations by the shoveling equipment and the number of times the drone truck exits the ore pass, calculate the amount of ore in the ore pass, and control the drone truck to perform intelligent loading of ore, so that the ore stored in the ore pass can be removed in a timely manner, which is convenient for construction teams with different efficiencies and prevents the danger caused by excessive ore storage in the ore pass.

[0023] Furthermore, the shovel and transport equipment can also be an unmanned device. The shovel and transport equipment is connected to the host network. The host automatically controls the shovel and transport equipment to identify the corresponding mine for loading ore and the corresponding ore pass for unloading ore based on the information of the first identification card, the base station, and the second identification card. When heading to the corresponding mine, the shovel and transport equipment is identified and guided by the base station of the shovel and transport equipment and the first identification card of the corresponding mine. When heading to the corresponding ore pass, the shovel and transport equipment is identified and guided by the base station of the shovel and transport equipment and the second identification card of the corresponding ore pass.

[0024] (III) Beneficial Effects

[0025] One of the above technical solutions has the following advantages or beneficial effects:

[0026] 1) To address the challenges of existing technologies where multiple mining teams and ore passes are used in mines to increase efficiency, ore loading and unloading processes cannot be tracked. Calculations rely on manual reporting, which can lead to errors in subsequent settlements. These errors include unloading into the wrong pass, loading into the wrong ore chamber, or misrecording vehicle type or number. This hinders verification and settlement by different teams, causing inconvenience in production management. A new technology addresses this by installing base stations and sensors on the shoveling equipment to detect unloading actions. Combined with a primary identification card for the ore chamber and a secondary identification card for the ore pass, the base station can identify the ore chamber and ore pass using the identification cards and upload information about the shoveling equipment. The system integrates sensors to determine whether the shovel and conveyor equipment is loading or unloading ore, enabling the main unit to accurately record the loading and unloading status of the corresponding equipment. This allows for tracking of the loading and unloading status of each equipment in each construction team, facilitating subsequent verification of ore production by each team, and simplifying the calculation of remaining ore and production volume in the mine. Furthermore, it accurately tracks ore conditions in case of subsequent calculation errors, reducing manual intervention and enabling rapid calculation. The system also automatically outputs daily ore production reports for each construction team and mine, facilitating monitoring of team performance. In conjunction with unmanned aerial vehicles (UAVs), the system can more promptly control UAVs for ore transport from the ore pass. Finally, a track scale at the unloading point allows the UAVs to weigh and record the ore unloading from the ore pass, facilitating subsequent calculation and comparison.

[0027] 2) To address the issue that existing technologies require manual control of loading and unloading of ore on the vehicle, resulting in low automation, and given that mining areas are often located inside mine shafts where manual work poses certain risks and is inconvenient, the shovel and haulage equipment can be made driverless. This can be achieved through remote wireless control or automatic control by the host system. The equipment can be located via base stations to avoid collisions, and the host system can automatically plan routes to the corresponding identification card, enabling automatic transport to the loading and unloading points. This significantly reduces the risks of manual driving inside the mine and also better prevents ore from being unloaded into the wrong chute. Attached Figure Description

Detailed Implementation

[0034] The present invention will be further described in detail below with reference to embodiments, but the implementation of the present invention is not limited thereto.

[0035] Implementation Plan 1:

[0036] This invention provides a ore pass management system: its structure includes a shovel and conveyor 1, a ore chamber 2, a track scale 6, an unmanned aerial vehicle (UAV) vehicle 7, an ore extraction device 8, and an ore pass 9. The ore chamber 2 is used for ore mining and storage. The shovel and conveyor 1 is used to transport minerals from the ore chamber 2 into the ore pass 9. The bottom of the ore pass 9 is connected to the ore extraction device 8. The UAV vehicle 7 is used to receive the ore extracted from the ore extraction device 8. The track scale 6 is used for weighing the UAV vehicle 7.

[0037] It also includes a first identification card 3, a base station 4, a host 5, a second identification card 10, and a sensor 11. The feed inlets of each chute 9 are equipped with a corresponding second identification card 10. Each mine chamber 2 is equipped with a first identification card 3. The base station 4 and the sensor 11 are both mounted on the shovel and conveyor equipment 1. The host 5 is network-connected to the base station 4, the track scale 6, the unmanned vehicle 7, the ore discharge equipment 8, and the sensor 11. The base station 4 is used to identify the information of the first identification card 3 and the second identification card 10 and transmit it to the host 5. The first identification card 3 is used to identify the information of the mine chamber 2, the second identification card 10 is used to identify the information of the chute 9, the base station 4 is used to identify and locate the information of the shovel and conveyor equipment 1, and the sensor 11 is used to detect the unloading action of the shovel and conveyor equipment 1.

[0038] Among them, base station 4 is a UWB base station.

[0039] The sensor 11 is a pressure sensor or a limit switch.

[0040] Among them, such as Figure 2 As shown, when the sensor 11 is a pressure sensor, the sensor is mounted on the pump rod of the unloading bucket of the shovel and conveying equipment, and the change value of the pump rod pressure of the unloading bucket of the shovel and conveying equipment is used to determine whether loading and unloading actions have been performed.

[0041] Among them, such as Figure 3 As shown, when the sensor 11 is a limit switch, the sensor is mounted on the mechanical arm of the unloading bucket of the shovel and conveying equipment, and the movement of the mechanical arm of the unloading bucket of the shovel and conveying equipment is used to determine whether a loading or unloading action has been performed.

[0042] Among them, such as Figure 4 As shown, the shovel and conveying equipment may also be equipped with a voice device 12.

[0043] The base station 4 and the first identification card 3 and the second identification card 10 are interchangeably mounted. The mine 2 and the ore pass 9 are equipped with the base station 4, and the shovel and transport equipment 1 is equipped with the identification card.

[0044] When the system is in use, identification cards or base stations 4 are installed at the shovel and conveyor equipment 1, the ore storage room 2, and the ore pass 9. The base station 4 reads the identification cards to determine the information of the shovel and conveyor equipment 1. When the shovel and conveyor equipment 1 performs loading or unloading actions, the sensor 11 of the shovel and conveyor equipment 1 transmits an action signal, which causes the host 5 to determine that loading or unloading has been performed and record it. This realizes the automatic calculation of the ore quantity in the ore storage room and can accurately track the ore from the ore storage room to the ore pass. In case of errors in ore extraction or unloading, it can accurately track the destination of the ore, reduce manual intervention, facilitate rapid calculation, and automatically output the daily ore extraction reports of the construction team and the ore storage room, making it easy to check the work status of the construction team. At the same time, combined with unmanned vehicles, the system can more timely control the unmanned vehicles to transport ore out of the ore pass. Then, through the track scale at the final unloading point, the unmanned vehicles can weigh and record the corresponding ore unloading at the ore pass, which is convenient for subsequent calculation and comparison.

[0045] Implementation Plan Two:

[0046] This embodiment provides a ore pass management system, which differs from Embodiment 1 in that: the mounting points of the base station 4, the first identification card 3, and the second identification card 10 are interchanged, the base station 4 is mounted on the mine 2 and the ore pass 9, and the identification card is mounted on the shovel and conveying equipment 1. This will increase the cost of use. At the same time, the mine 2 and the ore pass 9 need to provide power to the base station 4, which increases the workload and environmental risks and reduces the convenience.

[0047] When base station 4 is installed on shovel and transport equipment 1, it can use the power supply of shovel and transport equipment 1, and the vehicle can easily carry an additional power supply, which is more convenient.

[0048] In this embodiment, the other components not described, as well as the relative positions and connections between the components, are the same as in Embodiment 1, and the achieved effect remains unchanged.

[0049] Implementation Plan 3:

[0050] The present invention also provides an operation method for a ore pass management system, the method being as follows:

[0051] 1. Divide the work into more than one construction team, and allocate the chute 9 to each construction team. Identify the base station 4 through the host 5, and register the information of the shovel and transport equipment 1 corresponding to each base station 4 in the host 5.

[0052] 2. During ore extraction, after the shovel and transport equipment 1 enters the mine 2, the base station 4 installed on the shovel and transport equipment 1 will identify the first identification card 3 of the mine 2 and upload it to the host 5. After receiving the identification information of the first identification card 3, the host 5 will enter the ore loading judgment procedure. When the sensor 11 returns data that matches the ore loading action, the host 5 will determine that the shovel and transport equipment 1 equipped with the base station 4 has loaded ore and record it. When the sensor 11 does not return data that matches the ore loading action, the host 5 will determine that the shovel and transport equipment 1 equipped with the base station 4 is just passing by.

[0053] 3. When unloading ore into the ore pass 9, the base station 4 installed on the shovel and conveying equipment 1 will first identify the second identification card 10 of the ore pass 9 and then transmit it to the host 5. After receiving the identification information of the second identification card 10, the host 5 will enter the ore unloading judgment procedure. When the sensor 11 returns data that matches the ore unloading action, the host 5 will determine that the shovel and conveying equipment 1 equipped with the base station 4 has unloaded ore and record it. When the sensor 11 does not return data that matches the ore unloading action, the host 5 will determine that the shovel and conveying equipment 1 equipped with the base station 4 is passing by.

[0054] Fourth, after the host 5 receives a notification from the base station 4 of the corresponding ore pass 9 that ore is being unloaded, it controls the unmanned vehicle 7 to travel to the ore discharge equipment 8 of the corresponding ore pass 9, then controls the ore discharge equipment 8 to discharge ore onto the unmanned vehicle 7, and then controls the unmanned vehicle 7 to travel to the track scale 6 to weigh and record the ore before unloading.

[0055] 5. The host 5 calculates and compares the ore output according to the set fixed time or number of times. During the calculation, the full load weight is obtained by weighing the unmanned vehicle 7 after each shovel and conveyor equipment 1 is fully loaded. Then, the weight per cubic meter of each shovel and conveyor equipment 1 is obtained by dividing the full load weight of each shovel and conveyor equipment 1 by the full load capacity of each shovel and conveyor equipment 1. The ore output is obtained by multiplying the number of times each shovel and conveyor equipment 1 has been loaded by the recorded rated capacity and the weight per cubic meter coefficient. The total output of each group can be obtained by summing the total output of each shovel and conveyor equipment 1. Finally, the total output is compared with the total output weighed by the track scale 6.

[0056] 6. When the reported ore output of each group is within ±5% of the weighed ore output, it is determined that the reported ore output is accurate. When the reported ore output of each group exceeds ±5% of the weighed ore output, it is determined that the reported ore output is inaccurate, and manual verification is notified.

[0057] The host 5 can record the number of times the shovel and transport equipment 1 unloads ore into the ore pass 9, calculate the amount of ore in the ore pass based on the number of unloading times and the number of times the drone vehicle 7 removes ore, and control the drone vehicle 7 to perform intelligent ore loading, so that the ore stored in the ore pass 9 can be removed in a timely manner, which is convenient for construction teams with different efficiencies and prevents the danger caused by excessive ore storage in the ore pass 9.

[0058] The shovel and transport equipment 1 can also be an unmanned device. The shovel and transport equipment 1 is connected to the host 5 via a network. The host 5 automatically controls the shovel and transport equipment 1 to identify the corresponding mine 2 for loading ore and the corresponding ore pass 9 for unloading ore based on the information set by the first identification card 3, the base station 4, and the second identification card 10. When going to the corresponding mine 2, the shovel and transport equipment 1 is identified and guided by the base station 4 and the first identification card 3 of the corresponding mine 2. When going to the corresponding ore pass 9, the shovel and transport equipment 1 is identified and guided by the base station 4 and the second identification card 10 of the corresponding ore pass 9.

[0059] In operation, when the shovel and transport equipment 1 of each construction team is loading ore into the mine 2, the base station 4 of the shovel and transport equipment 1 will identify the first identification card 3 of the mine 2 and upload the information to the host 5. The host 5 will then enter the ore loading identification state. When the sensor 11 of the shovel and transport equipment 1 detects a status action, the host 5 will record that the mine 2 has discharged ore and record it; otherwise, it will be considered as passing through. After the shovel and transport equipment 1 is full of ore, it will travel to the assigned ore pass 9 to unload the ore. When it travels to the ore pass 9, the base station 4 of the shovel and transport equipment 1 will identify the second identification card 10 at the entrance of the ore pass 9 and upload the information to the host 5. When the shovel and transport equipment 1 identifies the second identification card 10 of the ore pass 9 and performs the unloading action, the sensor 11 will transmit the sensed value change or triggered electrical signal to the host 5. The host 5 will determine that the shovel and transport equipment 1 that has traveled to the ore pass 9 has unloaded ore based on the data or signal returned by the sensor 11. If there is no signal from the sensor 11, the shovel and transport equipment 1 will be considered as having unloaded ore. If the ore is unloaded through ore pass 9, it will not be recorded to avoid misjudgment of ore unloading and facilitate accurate recording. This allows for tracking of the ore unloading status of each construction team's equipment, facilitating subsequent verification of ore output by each construction team and tracking of ore conditions in case of subsequent calculation errors. It also reduces manual intervention, facilitates rapid calculation, and can automatically output daily ore output reports for construction teams and mines, making it easy to view the work status of construction teams. At the same time, combined with the unmanned vehicle vehicle 7, the system can more timely control the unmanned vehicle vehicle 7 to load and transport ore from ore pass 9, and then weigh it through the track scale 6 at the final unloading point, so that the unmanned vehicle vehicle 7 can record the corresponding ore unloading from ore pass 9, which is convenient for subsequent calculation. Because of the irregularity of the ore, there will be gaps when stacking it. At the same time, there may be losses or weighing errors during the ore falling and transportation process. The host 5 is set to allow the deviation between the total weighed ore output and the ore output reported by the construction team to be within ±5% of the weighed ore output, which is convenient for rapid calculation.

[0060] Furthermore, when the system is in use, the shovel and conveyor equipment 1 can also be set to unmanned operation. It can be controlled by manual remote wireless control or automatic control by the host. The vehicle positioning is achieved through the base station 4 of each shovel and conveyor equipment 1, which can better avoid collisions between vehicles. At the same time, the host 5 can automatically plan the route to the corresponding identification card, that is, the route to the mine 2 or the ore pass 9. The system has a high degree of automation, which reduces the risk of manual driving in the mine and can also better avoid the situation of unloading into the wrong ore pass.
