Description

Technical Field

[0001] This invention belongs to the fields of mine intelligent sensing, ore and rock identification, underground engineering test equipment and complex environment simulation technology. Specifically, it relates to an experimental platform that can simulate underground environmental factors such as dust, water mist, airflow, humidity, gas composition and complex lighting, and is used for the research and development and testing of ore and rock interface precise detection and identification technology and device. Background Technology

[0002] In the intelligent mining process of coal and metal mines, mining equipment needs to accurately identify the ore body, surrounding rock, interbedded rock, fault fracture zones, and the location of the ore-rock interface. The results of ore-rock interface identification directly affect the cutting trajectory planning, resource recovery rate, dilution rate control, equipment safety, and the level of unmanned mining. With the development of technologies such as machine vision, near-infrared, hyperspectral, lidar, structured light, and deep learning, ore-rock interface identification based on image, spectral, point cloud, or multi-source information fusion is gradually becoming an important supporting technology for intelligent mining equipment.

[0003] However, the underground environment is characterized by numerous disturbances, strong randomness, and difficulty in repeating operations. Mining operations are often accompanied by factors such as dust dispersion, water mist spraying, ventilation airflow, uneven lighting, humidity changes, and the flow of methane or other gases. These factors can cause changes in target surface brightness and contrast, image blurring, boundary occlusion, enhanced scattering and reflection, spectral feature shifts, and a decrease in sensor signal-to-noise ratio, making it difficult to directly apply recognition algorithms trained or calibrated in conventional laboratory environments to real underground working conditions.

[0004] Existing downhole environment simulation devices mostly focus on temperature and pressure environment, medium immersion, drilling fluid circulation, equipment reliability, or lighting performance testing. They typically lack standard interface samples for rock-mineral interface identification tasks, controllable dust-water mist interference, adjustable spectral illumination, in-cabin multimodal detection pose adjustment, and synchronous annotation of image recognition data. Although some devices have transparent observation windows and place cameras outside the cabin, the observation windows themselves introduce additional errors such as reflection, refraction, contamination, and spectral attenuation, making it difficult to accurately reflect the direct working state of the detection device in the downhole environment.

[0005] For testing tasks that focus on identifying rock-ore interface images and multimodal information, the stress state of the sample and the ambient temperature are not essential variables that determine the identification performance. Existing downhole environment simulation devices often have complex multi-directional loading and temperature control mechanisms, which not only significantly increase the platform size, manufacturing cost, and control difficulty, but also occupy internal space and interfere with the layout of detection devices.

[0006] Therefore, it is necessary to propose a dedicated experimental platform that aims at accurate detection and identification of the rock-mineral interface, and emphasizes the functions of visual interference environment reconstruction and multimodal acquisition and calibration. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to provide a platform for simulating complex underground environments and accurately detecting and identifying rock-ore interfaces, which aims to solve the problem that existing test devices are difficult to repeat and quantify under complex underground environmental conditions such as dust, water mist, light, and ventilation.

[0008] The present invention provides a platform for simulating complex underground environments and accurately detecting and identifying rock-ore interfaces, comprising an opaque, sealed environmental chamber.

[0009] The detection device system is located inside the sealed environmental chamber and includes a detection device and an installation structure for mounting the detection device.

[0010] The sample positioning system is set inside the sealed environmental chamber and is used to fix the sample at the ore-bearing rock interface and adjust the spatial orientation of the ore-bearing rock interface and its distance from the detection device.

[0011] An environmental interference generation system is used to generate environmental interference factors that affect the detection of the rock-ore interface within the sealed environmental chamber; the environmental interference generation system includes a dust generation system, a water mist generation system, a light control system, and a circulating air system.

[0012] A synchronous acquisition system is connected to the detection device and the environmental parameter sensors installed in the sealed environmental chamber, and is used to synchronously acquire detection data and environmental parameters under the control of the central control system.

[0013] The central control system is connected to the environmental interference generation system, the sample positioning system, and the synchronous acquisition system respectively, and is used to control the coordinated operation of the environmental interference generation system, the sample positioning system, and the synchronous acquisition system.

[0014] A data labeling system, connected to the synchronous acquisition system and the central control system, is used to generate label data for training or testing of the rock-mineral interface recognition algorithm based on the geometric information of the sample, the pose information of the sample provided by the central control system, and the detection data acquired by the synchronous acquisition system.

[0015] Furthermore, the sample positioning system includes a sample box for placing the sample and a position adjustment system for adjusting the sample's posture. The position adjustment system includes a linear displacement mechanism, a lifting mechanism connected to the linear displacement mechanism, a rotation adjustment mechanism connected to the lifting mechanism, and a pitch adjustment mechanism connected to the rotation adjustment mechanism. The sample box is mounted on the pitch adjustment mechanism. The linear displacement mechanism is used to adjust the distance between the rock-ore interface and the detection device. The lifting mechanism is used to adjust the height of the rock-ore interface. The rotation adjustment mechanism is used to adjust the azimuth angle of the rock-ore interface. The pitch adjustment mechanism is used to adjust the tilt angle of the rock-ore interface. The linear displacement mechanism, the lifting mechanism, the rotation adjustment mechanism, and the pitch adjustment mechanism are all connected to the central control system.

[0016] Furthermore, the dust generation system includes a dust storage bin, a dust metering feeder connected to the dust storage bin, a mixing chamber connected to the outlet of the dust metering feeder, a high-speed nozzle connected to the mixing chamber, a compressed air source connected to the high-speed nozzle, and a dust airflow conveying pipe connecting the mixing chamber and the sealed environmental chamber; the dust metering feeder and the compressed air source are respectively connected to the central control system for controlling the feeding rate and the start / stop of the air source.

[0017] Furthermore, the water mist generation system includes a water tank, a water pump connected to the water tank via an inlet, an atomizing nozzle disposed within a sealed environmental chamber, and a water pipe connecting the atomizing nozzle and the water pump; the water pump is connected to the central control system for controlling the start / stop and flow rate of the water pump.

[0018] Furthermore, the lighting control system includes an adjustable brightness LED lamp and a dimmer connected to the LED lamp; the dimmer is connected to the central control system and is used to adjust the brightness and on / off state of the LED lamp.

[0019] Furthermore, the circulating air system includes air inlets and outlets installed on opposite side walls of the sealed environment chamber, circulating air ducts connecting the air inlets and outlets, and circulating fans installed on the circulating air ducts.

[0020] Furthermore, the environmental parameter sensors include a dust concentration sensor, a water mist concentration sensor, a light intensity sensor, and a wind speed sensor.

[0021] Furthermore, the data labeling system includes a geometric calibration module and a label generation module; the geometric calibration module determines the spatial position of the rock-mineral interface in the detection data coordinate system through coordinate system transformation based on the geometric information of the sample and the pose information of the sample provided by the central control system; the label generation module is connected to the geometric calibration module and generates at least one of boundary labels, area labels, and environmental labels corresponding to the detection data based on the spatial position of the rock-mineral interface determined by the geometric calibration module.

[0022] Furthermore, the circulating air system also includes a dust collector, which is connected to the outlet of the circulating fan via an exhaust pipe. A first valve is installed on the circulating air pipe, and a second valve is installed on the exhaust pipe.

[0023] The beneficial effects of this invention are:

[0024] 1. Provides a repeatable testing platform for detecting and identifying rock-ore interfaces under complex downhole environments.

[0025] This invention, by setting up a sealed environmental chamber and integrating a dust generation system, a water mist generation system, a lighting control system, and a circulating air system within the chamber, can simulate the coupled environment of multiple factors such as dust, water mist, lighting changes, and ventilation in underground mines under controlled conditions. The central control system coordinates the operation of each system and can execute single-factor tests, multi-factor coupled tests, random disturbance tests, and repeatability calibration tests according to preset test procedures, realizing the repeatable testing of rock-ore interface detection and identification technology under complex environmental conditions.

[0026] 2. Eliminates optical media interference in the detection optical path.

[0027] This invention directly installs the detection device inside a sealed environmental chamber. There is no transparent isolation medium in the detection light path between the detection device and the sample, which avoids optical interference such as refraction, reflection and scattering of the detection light caused by traditional observation window glass, and ensures the authenticity and accuracy of the detection data.

[0028] 3. Automatic labeling of detection data was implemented.

[0029] This invention uses a data labeling system to automatically determine the spatial position of the rock-mineral interface in the detection data based on the geometric information of the sample, the sample pose information provided by the central control system, and the detection data collected by the synchronous acquisition system. It also generates corresponding boundary labels, area labels, and environmental labels, thereby improving the efficiency and consistency of data labeling.

[0030] 4. The sample pose is adjustable with multiple degrees of freedom.

[0031] The sample positioning system of the present invention includes a linear displacement mechanism, a lifting mechanism, a rotation adjustment mechanism, and a pitch adjustment mechanism, which can respectively adjust the distance between the rock interface and the detection device, the height of the rock interface, the azimuth angle, and the tilt angle, to meet the needs of multi-angle and multi-distance detection and provide diverse sample data for algorithm training.

[0032] 5. The separation of dust and water mist generation from their maintenance phases improves environmental stability and reduces energy consumption.

[0033] This invention employs a collaborative operation of a dust generation system, a water mist generation system, and a circulating air system. The dust and water mist generation systems cease operation once the internal environmental parameters reach set values, while the circulating air system continuously drives airflow to slow the settling rate of dust and water mist, extending the stable maintenance time of environmental parameters. When the dust or water mist concentration falls below a set threshold, the central control system briefly activates the corresponding generation system for supplementary spraying, maintaining the internal environmental parameters within the set range. This method avoids environmental parameter drift and energy waste caused by the continuous operation of the dust and water mist generation systems.

[0034] 6. Equipped with post-experiment safety purification function

[0035] The present invention has a dust collector installed on the air outlet side of the circulating air system. After the experiment, the circulating fan extracts the dust- and mist-containing gas in the chamber and sends it to the dust collector for purification. The purified gas is then discharged into the outside atmosphere, ensuring the safety of the experimental operation. Attached Figure Description

[0043] The sample positioning system 3 is installed in the sealed environmental chamber 1 and is used to fix the sample 31 of the ore-bearing rock interface and adjust the spatial orientation of the ore-bearing rock interface and its distance from the detection device 21.

[0044] An environmental interference generation system 4 is used to generate environmental interference factors that affect the detection of the rock-ore interface within the sealed environmental chamber; the environmental interference generation system 4 includes a dust generation system 41, a water mist generation system 42, a light control system 43, and a circulating air system 44.

[0045] The synchronous acquisition system 5 is connected to the detection device 21 and the environmental parameter sensor 6 installed in the sealed environmental chamber, and is used to synchronously acquire detection data and environmental parameters under the control of the central control system.

[0046] The central control system 7 is connected to the environmental interference generation system 4, the sample positioning system 3 and the synchronous acquisition system 5 respectively, and is used to control the coordinated operation of the environmental interference generation system, the sample positioning system and the synchronous acquisition system.

[0047] The data labeling system 8 is connected to the synchronous acquisition system 5 and the central control system 7, and is used to generate label data for training or testing of the rock-mineral interface recognition algorithm based on the geometric information of the sample 31, the pose information of the sample provided by the central control system, and the detection data acquired by the synchronous acquisition system.

[0048] In this embodiment, the sample positioning system 3 includes a sample box 32 for placing the sample 31 and a posture adjustment system 33 for adjusting the sample's posture. The posture adjustment system 33 includes a linear displacement mechanism 331, a lifting mechanism 332 connected to the linear displacement mechanism, a rotation adjustment mechanism 333 connected to the lifting mechanism, and a pitch adjustment mechanism 334 connected to the rotation adjustment mechanism. The sample box is mounted on the pitch adjustment mechanism.

The sample 31 can be pulled out from the slot 321, so that the sample box 32 can be replaced with samples with different mineral-rock interfaces. The mineral-rock interfaces include flat interfaces, undulating interfaces, discontinuous interfaces, rock-intercalated interfaces, gradient interfaces, and fracture-containing interfaces, etc., to simulate the mineral-rock boundary characteristics under different occurrence conditions. In a specific embodiment, the linear displacement mechanism 331 adopts an electric slide table, which is horizontally connected to the bottom of the sealed environmental chamber 1; the lifting mechanism 332 adopts an electric push rod, which is vertically connected to the electric slide table; the rotation adjustment mechanism 333 adopts a stepper motor, which is connected to the electric push rod through a base plate 335; the pitch adjustment mechanism 334 includes a support 3341 connected to the rotor of the stepper motor, a horizontal shaft 3342 connected to the support 3341, and a stepper motor 3343 that drives the horizontal shaft 3342 to rotate. The sample box 32 is fixed to the horizontal shaft 3342 by screws.

[0049] The linear displacement mechanism is used to adjust the distance between the rock-ore interface and the detection device; the lifting mechanism is used to adjust the height of the rock-ore interface; the rotation adjustment mechanism is used to adjust the azimuth angle of the rock-ore interface; and the pitch adjustment mechanism is used to adjust the tilt angle of the rock-ore interface. The linear displacement mechanism, the lifting mechanism, the rotation adjustment mechanism, and the pitch adjustment mechanism are respectively connected to the central control system. The central control system 7 can automatically control the movement of each mechanism according to a preset test program, achieving precise adjustment and automatic traversal of the sample 31's pose.

[0050] like Figure 3 As shown, in this embodiment, the mounting structure 22 of the detection device system 2 adopts the same structure as the pose adjustment system 33. The detection device 21 (including a visible light camera, a near-infrared camera, a lidar, or an ultrasonic detector) is first fixed on the base plate 23, and the base plate 23 is fixed on the horizontal axis of the pitch adjustment mechanism. Of course, in different embodiments, the mounting structure 22 can also adopt a fixed bracket.

[0051] In this embodiment, the dust generation system 41 includes a dust storage bin 411, a dust metering feeder 412 connected to the dust storage bin, a mixing chamber 413 connected to the outlet of the dust metering feeder, a high-speed nozzle 414 connected to the mixing chamber, a compressed air source 415 connected to the high-speed nozzle, and a dust airflow conveying pipe 416 connecting the mixing chamber and the sealed environmental chamber. In this embodiment, the dust metering feeder 412 is specifically a screw feeder, and the compressed air source 415 is an air compressor pump. The dust metering feeder and the compressed air source are respectively connected to the central control system for controlling the feeding rate and the start / stop of the air source.

[0052] In this embodiment, the water mist generating system 42 includes a water tank 421, a water pump 422 with an inlet connected to the water tank, an atomizing nozzle 423 with an outlet located in a sealed environmental chamber, and a water pipe 424 connecting the atomizing nozzle and the water pump; the water pump is connected to the central control system and is used to control the start and stop of the water pump and the flow rate.

[0053] In this embodiment, the lighting control system 43 includes an adjustable-brightness LED lamp 431 and a dimmer 432 connected to the LED lamp; the dimmer is connected to the central control system and is used to adjust the brightness and on / off state of the LED lamp. By adjusting the brightness of the LED lamp, different lighting conditions such as normal underground lighting, weak light, dim light, and local strong light can be simulated.

[0054] In this embodiment, the circulating air system 44 includes an air inlet 441 and an air outlet 442 disposed on opposite side walls of the sealed environmental chamber, a circulating air duct 443 connecting the air inlet and the air outlet, and a circulating fan 444 disposed on the circulating air duct. The circulating fan 444 drives airflow to be drawn out from the air outlet 442, and returns to the air inlet 441 through the circulating air duct 443, forming a uniform circulating airflow within the chamber. The circulating airflow is used to maintain the uniform distribution of dust and water mist within the chamber, slow down the settling rate of dust and water mist, and simulate underground ventilation conditions. Furthermore, the circulating air system also includes a dust collector 445, which is connected to the outlet of the circulating fan through an exhaust pipe 446. A first valve 447 is disposed on the circulating air duct, and a second valve 448 is disposed on the exhaust pipe. During the experiment, the first valve 446 is opened and the second valve 447 is closed. The circulating fan 444 drives the airflow to circulate between the sealed environmental chamber 1 and the circulating air duct 443, maintaining a stable environment inside the chamber. After the experiment, the first valve 446 is closed and the second valve 447 is opened. The circulating fan 444 extracts the dust- and mist-containing gas from the sealed environmental chamber 1 and sends it to the dust collector 445. After dust removal and purification, the gas is discharged into the outside atmosphere, ensuring experimental safety.

[0055] In this embodiment, the environmental parameter sensor 6 includes a dust concentration sensor 61, a water mist concentration sensor 62, a light intensity sensor 63, and a wind speed sensor 64. The dust concentration sensor 61 monitors the dust concentration inside the chamber, the water mist concentration sensor 62 monitors the water mist concentration inside the chamber, the light intensity sensor 63 monitors the light intensity inside the chamber, and the wind speed sensor 64 monitors the wind speed inside the chamber. In this embodiment, the dust concentration sensor 61, water mist concentration sensor 62, light intensity sensor 63, and wind speed sensor 64 are arranged in the middle of the sealed environmental chamber 1, accurately reflecting the environmental conditions along the detection path of the detection device 21. All sensors are connected to the synchronous acquisition system 5.

[0056] In this embodiment, the data annotation system includes a geometric calibration module and a label generation module. The geometric calibration module determines the spatial position of the ore-rock interface in the detection data coordinate system through coordinate system transformation based on the geometric information of the sample and the pose information of the sample provided by the central control system. Sample 31 is a standard rectangular sample with fixed geometric dimensions, and the position of the ore-rock interface in the sample coordinate system is a known parameter.

[0057] The tag generation module is connected to the geometric calibration module. Based on the spatial location of the ore-rock interface determined by the geometric calibration module, it generates at least one of the following: boundary tag, region tag, and environmental tag, corresponding to the detection data. The boundary tag is the outline of the ore-rock interface; the region tag is a mask separating the ore body and surrounding rock; and the environmental tag is annotated with current environmental parameters, including dust concentration, water mist concentration, light intensity, and wind speed.

[0058] The ore-rock interface detection and identification test method based on the platform described in the above embodiments includes the following steps:

[0059] Step 1: Install the sample 31 of the ore-bearing rock interface into the sample box 32 of the sample positioning system 3.

[0060] Step 2: Control the sample positioning system 3 through the central control system 7 to adjust the spatial attitude and detection distance of the ore-rock interface. Specifically, adjust the distance between the ore-rock interface and the detection device 21 through the linear displacement mechanism 331, adjust the height of the ore-rock interface through the lifting mechanism 332, adjust the azimuth angle of the ore-rock interface through the rotation adjustment mechanism 333, and adjust the tilt angle of the ore-rock interface through the pitch adjustment mechanism 334.

[0061] Step 3: Set environmental interference parameters and activate the environmental interference generation system 4 through the central control system 7. Specifically, set parameters such as dust concentration, water mist concentration, light intensity, and wind speed, and activate the dust generation system 41, water mist generation system 42, light control system 43, and circulating air system 44. The dust generation system 41 and water mist generation system 42 stop operating after the dust and water mist concentrations inside the cabin reach the set values, and the circulating air system 44 continuously drives airflow circulation to maintain a stable environment inside the cabin. When the dust or water mist concentration falls below the set threshold, the central control system 7 briefly activates the corresponding generation system for supplementary spraying to maintain the environmental parameters inside the cabin within the set range.

[0062] Step 4: After the environmental parameters inside the cabin stabilize, at least one of the following is collected by the detection device 21: visible light image, near-infrared image, or lidar point cloud data of the rock-mineral interface. At the same time, environmental parameter data monitored by the environmental parameter sensor 6 is collected by the synchronous acquisition system 5.

[0063] Step 5: Generate label data for training or testing the rock-mineral interface recognition algorithm using the data labeling system 8.

[0064] Furthermore, the method also includes step 6: evaluating the performance of the ore-rock interface detection and identification technology or device based on at least one of the following indicators: identification accuracy, boundary positioning error, anti-interference ability, stability, and repeatability.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
