Description

Technical Field

[0001] This utility model relates to the field of open-pit mine monitoring technology, and more specifically, to a device for real-time monitoring and data acquisition of open-pit mine resource reserves. Background Technology

[0002] Accurate estimation of mineral resource reserves and effective monitoring of the mining environment are crucial for the rational development and sustainable development of mines. However, existing technologies have many limitations in mine monitoring, making it difficult to achieve multi-dimensional and comprehensive monitoring of mineral resource reserves and real-time dynamic tracking of changes in the mining environment.

[0003] Regarding monitoring equipment, existing mine monitoring equipment often has limited functionality. Some devices can only perform simple topographic measurements and cannot analyze the composition and distribution of materials on the mine surface; others can acquire some spectral information, but it is difficult to construct accurate three-dimensional models to reflect the topography and ore body volume. Single devices cannot integrate information from multiple perspectives, significantly reducing the accuracy of resource reserve estimation and failing to provide a comprehensive and precise data foundation. Moreover, most existing equipment lacks the ability to monitor minute changes on the mine surface in real time, making it impossible to promptly capture situations such as ore mining progress and landslides, which is detrimental to the dynamic tracking and management of mine resource reserves.

[0004] Regarding equipment adaptability, existing mine monitoring devices typically lack flexible adjustment mechanisms. Due to the complex and diverse terrain of mines, different monitoring scenarios require varying positions and angles for the equipment. However, existing devices struggle to be flexibly adjusted according to actual terrain and monitoring needs, which affects the quality of monitoring data and fails to guarantee optimal monitoring results under all conditions, thus limiting the application of the devices in different mining environments.

[0005] Furthermore, due to the inability of existing technologies to achieve precise monitoring and dynamic management of mineral resource reserves, mining enterprises struggle to balance resource development and environmental protection during resource exploitation, hindering the sustainable development of the mining industry. Therefore, there is an urgent need for a mine monitoring device that integrates multiple monitoring equipment, possesses a flexible adjustment mechanism, a stable support structure, and can monitor safety hazards in real time, to address the problems of existing technologies. Therefore, this paper proposes a real-time monitoring and data acquisition device for open-pit mine resource reserves. Utility Model Content

[0014] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention integrates multiple monitoring devices, including a multispectral camera, a 3D laser scanner, and a lidar sensor. The multispectral camera can capture spectral information in different bands to analyze the material composition and distribution on the mine surface; the 3D laser scanner can construct an accurate 3D model of the mine, reflecting the topography and ore body volume; and the lidar sensor monitors minute changes on the mine surface in real time. The combination of these three devices enables multi-dimensional and comprehensive monitoring of mine resource reserves, providing a precise and comprehensive data foundation and greatly improving the accuracy of resource reserve estimation. The lidar sensor can detect changes on the mine surface in real time, such as ore mining progress and landslide conditions. Once a change occurs on the mine surface, the sensor can quickly capture and feed back the relevant information, enabling dynamic tracking of mine resource reserves.

[0015] The device achieves flexible adjustment of the position and angle of the lidar sensor through adjusting the chain, tensioning screw, linkage swing arm, and linkage V-shaped linkage mechanism. This flexible adjustment mechanism allows the device to adapt to different mine terrains and monitoring scenarios, ensuring that the lidar sensor can always acquire optimal monitoring data, thus improving the device's applicability and monitoring effect. The trapezoidal stone pier base provides stable support for the device, capable of withstanding various natural environmental conditions and equipment operating pressures, ensuring stable operation of the device under the complex geological and climatic conditions of open-pit mines.

[0016] The real-time monitoring function of lidar sensors on mine surface changes can promptly detect potential landslide hazards. Mine managers can take corresponding preventative measures based on the monitoring information. This device provides a scientific and precise means for resource management in open-pit mines, contributing to the rational development and sustainable utilization of resources. Through real-time monitoring and dynamic management of resource reserves, mining enterprises can better balance the relationship between resource development and environmental protection, promoting the sustainable development of the mining industry.

It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Example 1: A real-time monitoring and data acquisition device for open-pit mine resource reserves includes a trapezoidal stone pier base 1 and a steel bar connecting rod 2 set at the top of the trapezoidal stone pier base 1. A device support rod 3 is welded to the top of the steel bar connecting rod 2. A fixed pulley mounting frame 4 is fixed to one side of the bottom of the device support rod 3. An adjusting chain fixed pulley 5 is installed in the fixed pulley mounting frame 4. A monitoring and acquisition main frame 11 is installed on the top of the device support rod 3. A mine resource reserve monitoring and data acquisition component is set on the monitoring and acquisition main frame 11. A top crossbar 6 is installed on one side of the top of the device support rod 3. A linkage swing rod 7 is connected to the top crossbar 6.

[0029] The tail end of the linkage lever 7 is equipped with a linkage rod 8, and an adjusting chain 9 connects the adjusting chain pulley 5 and the linkage rod 8. A tension adjusting screw 10 is provided on the adjusting chain 9. The mine resource reserve monitoring data acquisition component includes a multispectral camera 12 and a three-dimensional laser scanner 13. The multispectral camera 12 and the three-dimensional laser scanner 13 are respectively connected to the main monitoring and acquisition frame 11.

[0030] A signal amplifier 14 is installed on one side of the main frame 11 for monitoring and data acquisition, and a wireless data transmission antenna 15 is connected above the signal amplifier 14. A radar sensor mounting plate 16 is installed on the other side of the main frame 11, and a lidar sensor 17 is installed on the outer plate 16. A connecting pin 18 is provided at the rear end of the radar sensor mounting plate 16, and a linkage V-shaped connecting rod 19 is connected to the connecting pin 18. The other end of the linkage V-shaped connecting rod 19 is connected to the linkage swing rod 7.

[0031] The working principle of the real-time monitoring and data acquisition device for open-pit mine resource reserves: A multispectral camera 12 is installed on the main monitoring and acquisition frame 11, which can capture spectral information in different bands. In the open-pit mine environment, different types of ore, as well as the surrounding geological structures and vegetation, have unique reflection characteristics in different spectral bands. By capturing multispectral images of the mining area, the multispectral camera analyzes the reflection intensity and distribution of different spectral bands in these images, thereby obtaining information on the composition and distribution of materials on the mine surface, providing basic data for the estimation of resource reserves.

[0032] The 3D laser scanner 13 is also mounted on the monitoring and acquisition main frame 11. Utilizing the principle of laser ranging, it emits a laser beam into the mining area and measures the time it takes for the laser beam to travel from emission to reflection back to the receiver, thereby calculating the distance from the scanning point to the instrument. Through continuous rotation and scanning, the 3D laser scanner can acquire the 3D coordinate information of a large number of points on the mine surface, thus constructing a 3D model of the mine. This 3D model accurately reflects the mine's topography, ore body shape, and volume information, serving as a crucial basis for calculating mine resource reserves.

[0033] The lidar sensor 17 is mounted on the lidar sensor mounting plate 16. It detects the distance, speed, and angle of a target object by emitting laser pulses and measuring their reflected signals. In mine monitoring, the lidar sensor can monitor minute changes on the mine surface in real time, such as ore mining and landslides. When changes occur on the mine surface, the reflected signals detected by the lidar sensor will change accordingly. By analyzing these changes, dynamic information about the mine can be grasped in a timely manner, further improving the real-time performance and accuracy of resource reserve monitoring.

[0034] The data acquired by the multispectral camera 12, the 3D laser scanner 13, and the lidar sensor 17 are typically weak electrical signals, requiring amplification for effective transmission and analysis. The signal amplifier 14, installed on one side of the monitoring and acquisition main frame 11, amplifies the acquired weak signals, enhancing their strength and stability to ensure accurate data transmission.

[0035] The signal amplified by signal amplifier 14 is transmitted wirelessly via wireless data transmission connection antenna 15. Wireless data transmission connection antenna 15 can send the processed data to a remote data processing center or monitoring terminal.

[0036] An adjusting chain 9 connects the adjusting chain fixed pulley 5 and the linkage rod 8, and a tension adjusting screw 10 is installed on the adjusting chain 9. The tension of the adjusting chain 9 can be adjusted by rotating the tension adjusting screw 10. The tension of the adjusting chain 9 affects the movement of the linkage swing rod 7, thereby indirectly affecting the position and angle of the linkage V-shaped connecting rod 19 and the lidar sensor 17 connected to the linkage swing rod 7. This adjustment mechanism allows for adjustment of the scanning range and angle of the lidar sensor 17 according to actual monitoring needs, in order to obtain more comprehensive and accurate mine data.

[0037] One end of the linkage lever 7 is connected to the top crossbar 6, and the other end is equipped with a linkage rod 8, which is connected to the adjusting chain pulley 5 via the adjusting chain 9. One end of the linkage V-shaped connecting rod 19 is connected to the radar sensor mounting plate 16 via a connecting pin 18, and the other end is connected to the linkage lever 7. When the tension of the adjusting chain 9 changes, the linkage lever 7 will swing around the top crossbar 6, thereby driving the linkage V-shaped connecting rod 19 to move. The movement of the linkage V-shaped connecting rod 19 will cause the radar sensor mounting plate 16 to rotate around the connecting pin 18, realizing the angle adjustment of the lidar sensor 17, so that it can adapt to different mine monitoring scenarios.

[0038] The open-pit mine resource reserve real-time monitoring and data acquisition device collects relevant data from the mine using a variety of monitoring devices, including multispectral cameras, 3D laser scanners, and lidar sensors. After signal amplification and wireless data transmission, the data is sent to a remote terminal for processing and analysis. At the same time, the angle of the monitoring equipment is adjusted using adjusting chains, linkage swing rods, and linkage V-shaped linkage mechanisms, thereby achieving real-time and accurate monitoring of open-pit mine resource reserves.

[0039] Working process of the real-time monitoring and data acquisition device for open-pit mine resource reserves: Base installation: First, the trapezoidal stone pier base 1 is firmly placed in a suitable monitoring position in the open-pit mine to ensure that the entire device has a stable supporting foundation and can withstand the pressure of various natural environments and equipment operation. Reinforcing steel connecting rods 2 are installed at the top of the trapezoidal stone pier base 1. Then, the device support rods 3 are welded to the top of the reinforcing steel connecting rods 2, completing the construction of the main frame of the device.

[0040] Install a fixed pulley mounting bracket 4 on one side of the bottom of the device support rod 3, and install an adjusting chain fixed pulley 5 therein. Install the monitoring and acquisition main frame 11 on the top rod of the device support rod 3, and at the same time install the top crossbar 6 on one side of the top of the device support rod 3 to prepare for the installation of subsequent components.

[0041] A multispectral camera 12, a 3D laser scanner 13, a signal amplifier 14, a wireless data transmission connection antenna 15, a radar sensor mounting plate 16, and a lidar sensor 17 are respectively installed on the main monitoring and acquisition frame 11. After installation, each device is initialized and debugged to ensure normal operation. For example, the shooting parameters of the multispectral camera and the scanning range and accuracy of the 3D laser scanner are set.

[0042] Install the linkage lever 7 on the top crossbar 6, and install the linkage rod 8 at the tail end of the linkage lever 7. Then, connect the adjusting chain fixed pulley 5 and the linkage rod 8 with the adjusting chain 9, and install the tension adjusting screw 10 to adjust the chain tension. Connect one end of the linkage V-shaped connecting rod 19 to the radar sensor mounting plate 16 through the connecting pin 18, and connect the other end to the linkage lever 7.

[0043] The multispectral camera 12 captures multispectral images of the open-pit mine area according to preset shooting parameters and time intervals. It captures spectral information in different bands and records the reflection characteristics of the surface material of the mine in each spectral band to obtain information on the composition and distribution of the surface material of the mine.

[0044] After the 3D laser scanner 13 is started, it emits a laser beam into the mining area. By measuring the time it takes for the laser beam to travel from emission to reflection back to the receiver, the distance from the scanning point to the instrument is calculated. It continuously rotates and scans to acquire the 3D coordinate information of a large number of points on the mine surface, constructing a 3D model of the mine for analysis of its topography and ore body volume.

[0045] The lidar sensor 17 continuously emits laser pulses, measures the reflected signals, and monitors minute changes on the mine surface in real time, such as ore mining and landslides. It detects the distance, speed, and angle of target objects, providing data support for real-time dynamic monitoring of mine resource reserves.

[0046] The weak electrical signals collected by the multispectral camera 12, the three-dimensional laser scanner 13, and the lidar sensor 17 are transmitted to the signal amplifier 14. The signal amplifier 14 amplifies these signals to enhance their strength and stability, ensuring that the data can be accurately transmitted and analyzed in subsequent processes.

[0047] The amplified signal is transmitted wirelessly via antenna 15. This data is then sent to a remote data processing center or monitoring terminal for further analysis and processing by professionals.

[0048] The operator adjusts the tension of the adjusting chain 9 by rotating the tension adjusting screw 10. Changes in the tension of the adjusting chain 9 affect the movement of the linkage lever 7.

[0049] The linkage lever 7 swings around the top crossbar 6, driving the connected linkage V-shaped link 19 to move. The movement of the linkage V-shaped link 19 causes the radar sensor mounting plate 16 to rotate around the connecting pin 18, thereby adjusting the position and angle of the lidar sensor 17 to adapt to different mine monitoring scenarios and acquire more comprehensive and accurate mine data. After receiving the data transmitted from the device, the remote data processing center uses specialized software to analyze and process this data. Combined with a pre-established resource reserve estimation model, the real-time resource reserves of the mine are calculated.

[0050] The real-time monitoring and data acquisition device for open-pit mine resource reserves uses an RS-7900 multispectral camera 12, installed on the main monitoring and acquisition frame. It can capture spectral information in different bands. Because different ores, geological structures, and vegetation in open-pit mines have different reflection characteristics in different spectral bands, the camera captures multispectral images, analyzes the reflection intensity and distribution, and obtains the material composition and distribution on the mine surface, providing basic data for reserve estimation. A RIEGL VZ-4000 three-dimensional laser scanner 13 is also installed on the main frame. Based on the principle of laser ranging, it emits a laser beam and measures the reflection time to calculate the distance to the scanning point. Through rotational scanning, it obtains a large number of three-dimensional coordinates of points, constructing a three-dimensional model that accurately reflects the topography, ore body shape, and volume, serving as an important basis for reserve calculation. A Velodyne HDL-64E lidar sensor 17 is installed on the lidar sensor mounting plate, emitting laser pulses and measuring the reflection signal to detect the target distance, speed, and angle. It can monitor minute changes on the mine surface in real time, such as mining and landslides, and grasp the dynamics of the mine by analyzing changes in reflected signals, thereby improving the real-time performance and accuracy of monitoring.

[0051] The weak electrical signals collected by the aforementioned equipment are amplified by a PA-500 signal amplifier 14 to enhance signal strength and stability, ensuring accurate data transmission. The amplified signal is then wirelessly transmitted to a remote data processing center or monitoring terminal via a TP-LINK TL-WA901ND wireless data transmission antenna. An adjusting chain connects to a fixed pulley and a linkage rod, with a tension adjusting screw mounted on it. Rotating the screw adjusts the chain tension, affecting the movement of the linkage swing arm, which in turn adjusts the position and angle of the linkage V-shaped connecting rod and the lidar sensor connected to the linkage swing arm, thereby obtaining more comprehensive and accurate mine data.
