[0020] The following describes the method and device for determining the metal resource amount of coal in an embodiment of the present application with reference to the accompanying drawings.

[0021] Figure 1 is a flow chart of a method for determining the metal resource amount of coal provided in an embodiment of the present application, such as Figure 1 As shown, the method for determining the metal resource amount of coal in the embodiment of the present application includes but is not limited to the following steps:

[0022] S101, determining the concentration of metal elements in the coal resources on the conveyor belt.

[0023] It should be noted that the execution subject of the method for determining the amount of metal resources of coal provided in the embodiment of the present application is an electronic device, which may be a terminal device. Optionally, the terminal device may be a mobile electronic device or a non-mobile electronic device. Exemplarily, the mobile electronic device may be a mobile phone, a tablet computer, a laptop computer, a PDA, an in-vehicle electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a personal digital assistant (PDA), etc., and the non-mobile electronic device may be a personal computer (PC), a television, etc. The embodiment of the present application is not specifically limited.

[0024] In some embodiments, the concentration of metal elements in coal resources on a conveyor belt can be detected based on laser induced breakdown spectroscopy technology.

[0025] In some embodiments, a laser is emitted to the coal resources on the conveyor belt to excite plasma, and a characteristic spectrum emitted by the plasma is collected by a spectrometer to obtain a laser induced breakdown spectrum. Furthermore, the metal elements present in the coal resources can be determined based on the characteristic spectrum lines in the laser induced breakdown spectrum, and the concentration of the metal elements can be determined based on the peak values ​​of the characteristic spectrum lines. The peak value generally indicates the maximum intensity of the spectrum line and is a key parameter reflecting the concentration of the element.

[0026] S102, obtaining the amount of coal transported by the conveyor belt within a set unit time.

[0027] In some embodiments, the volume and density of the coal resources transported by the conveyor belt within a set unit time are obtained, and then the amount of coal transported within the set unit time is calculated based on the volume and density of the coal resources.

[0028] In some embodiments, the coal flow rate transmitted by the conveyor belt within a set unit time can be detected based on a coal flow rate detector, and the volume of the coal resource can be calculated based on the coal flow rate and unit time. The coal flow rate detector includes a line laser and a binocular stereo camera.

[0029] In some embodiments, image point cloud data of the conveyor belt is collected and the density of the coal resources is determined using the point cloud data.

[0030] For example, the point cloud density of the point cloud data can be determined, and the corresponding relationship between the point cloud density and the coal density can be obtained. The coal density can be determined by querying the corresponding relationship using the point cloud density as the density of the coal resource.

[0031] S103, determining the resource amount of the metal element according to the concentration of the metal element and the amount of coal.

[0032] In some embodiments, the resource amount of metal elements refers to the total mass of metal elements contained in coal resources. That is, the product of the concentration of metal elements in coal resources and the amount of coal is calculated, and the result of the product is used as the resource amount of metal elements.

[0033] In the method for determining the amount of metal resources in coal provided in the embodiment of the present application, by obtaining the concentration of metal elements in the coal resources on the conveyor belt and the amount of coal conveyed per unit time, the amount of metal elements in the coal resources can be calculated based on the concentration of metal elements and the amount of coal. The detection of metal elements based on laser induced breakdown spectroscopy technology can improve the accuracy and type of metal element detection, and can quickly evaluate the amount of metal resources to determine its potential extraction value, which can provide rapid and comprehensive guidance for coal pricing, refined mining and utilization, and upstream and downstream supply and demand relationships.

[0034] Figure 2 is a flow chart of a method for determining the metal resource amount of coal provided in an embodiment of the present application, such as Figure 2 As shown, the method for determining the metal resource amount of coal in the embodiment of the present application includes but is not limited to the following steps:

[0035] S201, determining the concentration of metal elements in the coal resources on the conveyor belt.

[0036] In the embodiment of the present application, the implementation method of step S201 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0037] S202, determining the coal flow rate of the conveyor belt by using a line laser and a binocular stereo camera.

[0038] In some embodiments, a line laser sensor can be used to emit a line laser to the coal resources on the conveyor belt. As the conveyor belt moves, the shape and height changes of the surface of the coal resources will cause the line laser line to bend and displace. By detecting the degree of bending and displacement of the line laser line, the three-dimensional contour information of the coal resources can be obtained.

[0039] In some embodiments, images of the conveyor belt can be collected based on a binocular stereo camera, and the three-dimensional coordinates of the coal resources on the conveyor belt can be determined based on the images. Then, based on the three-dimensional contour information and three-dimensional coordinates of the coal resources, the coal flow on the conveyor belt can be calculated.

[0040] S203, obtaining a point cloud map of the conveyor belt, and determining the density of coal resources based on the point cloud map.

[0041] In some embodiments, stereo matching and three-dimensional reconstruction can be performed based on the image of the conveyor belt captured by the binocular stereo camera to obtain a point cloud map of the conveyor belt. The conveyor belt can also be laser scanned based on a line laser to obtain a point cloud map of the conveyor belt.

[0042] Furthermore, the point cloud density in the point cloud map can be determined, and the pre-established correspondence between the point cloud density and the coal density can be obtained. That is, after obtaining the point cloud density, the coal density can be determined based on the correspondence as the density of the coal resource.

[0043] S204, determining the volume of coal resources according to the coal flow rate and unit time.

[0044] S205, determining the amount of coal according to the density and volume of the coal resources.

[0045] In some embodiments, the volume of the coal resource can be obtained by calculating the product between the coal flow rate and the unit time, and the product between the density and the volume of the coal resource can be further calculated to obtain the amount of coal. In other words, the product of the coal flow rate and the unit time is the volume of the coal resource, and the product of the density and the volume of the coal resource is the amount of coal.

[0046] S206, determining the resource amount of the metal element according to the metal element concentration and the coal amount.

[0047] In the embodiment of the present application, the implementation method of step S206 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0048] In the method for determining the amount of metal resources in coal provided in the embodiment of the present application, the amount of coal can be calculated by obtaining the volume and density of the coal resources transported on the conveyor belt per unit time, so as to realize real-time monitoring of the coal resources and improve the accuracy of determining the metal elements in the coal resources.

[0049] Figure 3 is a flow chart of a method for determining the metal resource amount of coal provided in an embodiment of the present application, such as Figure 3 As shown, the method for determining the metal resource amount of coal in the embodiment of the present application includes but is not limited to the following steps:

[0050] S301, controlling the laser equipment to emit laser to the coal resources on the conveyor belt to excite plasma.

[0051] It is understandable that laser-induced breakdown spectroscopy is a spectral analysis technology based on the interaction between laser and matter. When a high-power density laser beam is focused on the surface of coal resources, the laser energy is rapidly absorbed and causes the local rapid heating, vaporization and even ionization of the coal resources, thereby forming plasma. The spectrum radiated by the plasma contains the characteristic spectral lines of various elements in the coal resources. Through spectral analysis, the elemental composition and content information of the coal resources can be obtained.

[0052] In some embodiments, before emitting laser to the coal resources, laser parameters such as wavelength, energy, pulse width, etc. can be determined, and according to the set laser parameters, the laser equipment can be controlled to emit laser to the coal resources on the conveyor belt, thereby exciting plasma.

[0053] In some embodiments, synchronous control needs to be achieved between the laser device and the conveyor belt to ensure that the emitted laser can accurately hit the coal resources on the conveyor belt and move with the movement of the coal resources.

[0054] S302, collecting characteristic spectra of the plasma to generate a laser induced breakdown spectrum.

[0055] In some embodiments, a characteristic spectrum of the plasma can be collected based on a spectrometer, and the characteristic spectrum can be graphed to generate a laser induced breakdown spectrum. The laser induced breakdown spectrum usually includes characteristic spectral lines of different metal elements and their corresponding intensity information.

[0056] S303, determining the metal elements contained in the coal resources and the metal element concentrations corresponding to the metal elements according to the laser induced breakdown spectroscopy.

[0057] In some embodiments, by determining the first characteristic spectral line in the laser induced breakdown spectrum and comparing the first characteristic spectral line with the second characteristic spectral lines corresponding to multiple different metal elements, if there is a second characteristic spectral line that is the same as the first characteristic spectral line, it can be determined that the metal element corresponding to the second characteristic spectral line is the metal element contained in the coal resources.

[0058] In some embodiments, by determining a first intensity corresponding to a first characteristic spectrum line and determining a second intensity corresponding to a known metal element concentration, the metal element concentration corresponding to the metal element is determined based on the first intensity and the second intensity.

[0059] In some embodiments, a relationship table between characteristic spectral line intensity and metal element concentration can be determined based on the second intensity and the metal element concentration corresponding to the second intensity. After obtaining the first intensity, the metal element concentration corresponding to the first intensity can be obtained by looking up the relationship table or performing an interpolation operation on the relationship table, and the metal element concentration can be used as the metal element concentration corresponding to the metal element contained in the coal resources.

[0060] S304, obtaining the amount of coal transported by the conveyor belt within a set unit time.

[0061] In the embodiment of the present application, the implementation method of step S304 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0062] S305, determining the resource amount of the metal element according to the metal element concentration and the coal amount.

[0063] In the embodiment of the present application, the implementation method of step S305 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0064] In the method for determining the metal resource amount of coal provided in the embodiment of the present application, the detection of metal elements is based on laser induced breakdown spectroscopy technology, which can improve the accuracy and type of detected metal elements, realize rapid evaluation of metal resource amounts, and judge their potential extraction value, and can provide rapid and comprehensive guidance for coal pricing, refined mining and utilization, and upstream and downstream supply and demand relationships.

[0065] Figure 4 is a flow chart of a method for determining the metal resource amount of coal provided in an embodiment of the present application, such as Figure 4 As shown, the method for determining the metal resource amount of coal in the embodiment of the present application includes but is not limited to the following steps:

[0066] S401, for each metal element contained in the coal resources, obtaining a concentration threshold value corresponding to the metal element.

[0067] S402, judging whether the metal element meets a set condition according to the metal element concentration and the concentration threshold.

[0068] S403, in response to any metal element satisfying a set condition, raising the base price of coal resources.

[0069] In some embodiments, in order to achieve flexible pricing of coal resources, the coal resources may be priced according to the amount of metal elements in the coal resources. Alternatively, the base price of the coal resources may be adjusted according to the concentration of the metal elements.

[0070] In some embodiments, the concentration threshold corresponding to each metal element contained in the coal resource is determined, and the metal element reaching the concentration threshold is regarded as satisfying the set condition. In other words, in response to the metal element concentration being greater than or equal to the concentration threshold, it is determined that the metal element satisfies the set condition.

[0071] In some embodiments, if any metal element in the coal resource satisfies the set conditions, it means that the coal resource has a higher economic value, and the base price of the coal resource can be increased. If no metal element in the coal resource satisfies the set conditions, the base price of the coal resource can be maintained unchanged or reduced.

[0072] In some embodiments, the base price of coal resources can be adjusted according to different types and quantities of metal elements. The base price of coal resources is adjusted based on the price increase coefficient by determining the target metal element in the coal resources that meets the set conditions and determining the price increase coefficient of the coal resources according to the target metal element.

[0073] Optionally, the price increase coefficient of the coal resource is determined by determining the amount and type of the target metal element and based on at least one of the amount and type of the target metal element.

[0074] Optionally, a correspondence between different types and quantities and price increase coefficients may be established. When the quantity and type of the target metal element are determined, the price increase coefficient of the coal resource may be determined by querying the correspondence.

[0075] In some embodiments, when any metal element meets the set conditions, the mining strategy of coal resources can also be adjusted to reduce the impact of metal impurities on coal quality. When any metal element meets the set conditions, the market demand for the metal element can also be analyzed to adjust the upstream and downstream supply and demand relationship.

[0076] That is to say, in response to any metal element satisfying the set conditions, the mining strategy and upstream and downstream supply and demand relationships of coal resources are adjusted.

[0077] For example, the quality of coal can be improved by improving the mining method. Another example is to cooperate with downstream smelting companies to extract and process the metal elements in coal, thus forming a synergistic effect between the upstream and downstream of the industrial chain.

[0078] In the method for determining the metal resource amount of coal provided in the embodiment of the present application, the metal concentration in the coal resources is determined, and the basic price of the coal resources is adjusted when the metal concentration meets the set conditions, so as to increase the value of the coal resources, promote the rational use of resources, and optimize the market supply and demand relationship, thereby maintaining market stability.

[0079] Figure 5 Shown is a schematic diagram of the process of determining the resource quantity of metal elements in coal resources.

[0080] For the coal resources on the conveyor belt, laser induced breakdown spectroscopy is used to detect the metal elements contained in the coal resources and the concentration of the metal elements, and it is determined whether the concentration of the metal elements meets the set conditions. When the set conditions are met, the coal flow rate transmitted by the conveyor belt per unit time is detected based on the coal flow detector, and the density of the coal resources is determined according to the point cloud map of the conveyor belt, and the volume of the coal resources transmitted per unit time is calculated. Therefore, according to the density and volume of the coal resources, the amount of coal transmitted by the conveyor belt in the set unit time is calculated, and then the product of the metal element concentration and the coal amount can be calculated as the resource amount of the metal element.

[0081] In some embodiments, when the concentration of metal elements meets the set conditions or when the concentration of metal elements does not meet the set conditions, the basic price of coal resources can be adjusted, as well as the coal mining strategy and upstream and downstream supply and demand relationships.

[0082] For example, if the set conditions are met, the basic price of coal resources can be increased; if the set conditions are not met, the basic price of coal resources can be reduced or maintained unchanged.
