[0053] Those skilled in the art will understand that Figure 1 The structure shown is merely a block diagram of a portion of the structure related to the present application and does not constitute a limitation on the computer device to which the present application is applied. Specific computer devices may include more or fewer components than those shown in the figure, or combine certain components, or have different component arrangements.
[0054] In one embodiment, such as Figure 2 As shown, Figure 2 This is a flowchart illustrating a method for ore grade analysis provided in an embodiment of this application, applied to... Figure 1 Taking a computer device as an example, the explanation includes the following steps:
[0055] S201, when no ore sample is placed in the target area and a first radiation source is set at the first and second positions in the target area, determine the first detection efficiency at the first position and the second detection efficiency at the second position.
[0056] The first radiation source refers to an isotope radiation source with known activity. When the first radiation source is set at the first and second positions in the target area, the order of placement needs to be distinguished. The first radiation source can be placed at the first position first and then at the second position, or the first radiation source can be placed at the second position first and then at the first position.
[0057] Specifically, for example, such as Figure 3 As shown, Figure 3 This is a scene comparison diagram of an ore grade analysis method provided in the embodiments of this application, such as... Figure 3 As shown, when no ore sample is placed in the target area, the first detection efficiency ε at position 301 is determined using an isotope X-ray source with known activity. p10 The second detection efficiency ε at position 302 p20 Detector 303 is used to detect the target ray count emitted by the isotope radiation source, and detector 304 is used to detect the target ray count emitted by reference plates 305 and 306, as well as the ore sample. If the target ray emitted by the radiation source is gamma ray, and its energy is close to that of the gamma rays emitted by reference plates 305, 306, and the ore sample, then ε can be determined based on the ratio of the actual gamma ray count emitted by the radiation source at positions 301 and 302 to the gamma ray count detected by detector 303. p10 With ε p20 .
[0058] If the energy of the gamma rays emitted by the X-ray source differs significantly from the energy of the gamma rays emitted by reference plates 305, 306, and the ore sample, then it is necessary to use X-ray sources of different energies multiple times to determine the function curve between the energy of the gamma rays emitted by the X-ray source at position 301 or 302 and the detection efficiency at that position. Based on this function curve, the energy of the gamma rays emitted by reference plates 305, 306, and the ore sample is substituted into the function to determine ε. p10 With ε p20 If different energy radiation sources are used, they can be placed in the first and second positions simultaneously.
[0059] S202, when a ore sample is placed in the target area and a first reference sheet is set at the first position, the flux rate of the second radiation source is determined according to the first detection efficiency; the second radiation source is used to excite the first reference sheet to release target radiation.
[0060] The second radiation source can be any type of radiation source that emits neutrons or photons, used to excite the first reference sheet, the second reference sheet, and the ore sample to emit target radiation. The selection of the reference sheet should meet the following criteria: the energy of the target radiation emitted by the reference sheet is close to the energy of the target radiation emitted by the target element in the ore; the ore does not contain the same element as the reference sheet; the target radiation emitted by the reference sheet accounts for the largest proportion of all its emitted radiation; and the reference sheet does not have a significant shielding effect on the detector. Specific reference sheet element types are shown in Table 1.
[0061] Table 1
[0062]
[0063] Specifically, with Figure 3 Taking the scenario shown as an example, since the medium between the reference piece 305 at position 301 and the detector does not change whether the target area has no ore sample or has one, the detection efficiency ε of the reference piece 305 remains the same. Therefore, when the target area has an ore sample and the reference piece 305 is positioned at position 301, the detection efficiency ε of the reference piece 305 is [not specified]. p1 =ε p10 Optionally, the detection efficiency ε of reference piece 305 can be used as a reference. p1 The flux rate Φ of the second radiation source is determined by multiplying the product of the first preset coefficient.
[0064] S203, when an ore sample is placed in the target area and a second reference piece is set at the second position, the third detection efficiency of the second reference piece at the second position is determined according to the injection rate.
[0065] Specifically, with Figure 3 Taking the situation shown in the figure as an example, when a ore sample is placed in the target area and a reference plate 306 is set at position 302, the medium between the reference plate 306 and the detector changes due to the addition of the ore sample. At this time, it is necessary to calculate the third detection efficiency ε of the reference plate 306 at position 302. p2 .
[0066] Optionally, the third detection efficiency ε of the reference piece 306 at position 302 can be determined by multiplying the flux rate Φ of the second X-ray source determined in the above steps by a second preset coefficient. p2 .
[0067] S204. Based on the second detection efficiency, the third detection efficiency, and the target ray count value of the ore sample, the grade analysis results of the ore sample are determined.
[0068] The grade of an ore sample refers to the content of useful components or minerals per unit volume or unit weight of ore, and is generally expressed as a weight percentage.
[0069] Specifically, with Figure 3 The following example illustrates the situation, based on the ε determined by the steps described above. p2 With ε p20 Determine the detection efficiency ε of the ore sample. p According to the detection efficiency ε p The target X-ray count value C and the flux rate Φ of the ore sample are used to determine the atomic number N of the target element in the ore sample, and then the grade of the ore sample is determined based on N.
[0070] Figure 4 This is a structural diagram of an ore grade analysis system provided in an embodiment of this application. For example... Figure 4As shown, the system includes a fixed shield 401, movable shields 402 and 403, an ore sample 404, a second radiation source 405, a conveyor belt 406, and detectors 407 and 408. The second radiation source releases neutrons or photons to irradiate the ore sample 404. The fixed shield 401, movable shields 402 and 403 prevent radiation diffusion. After irradiation, the ore sample 404 releases target radiation. The movable shields 402 and 403 are then opened, and the conveyor belt moves the ore sample 404 to the positions of detectors 407 and 408. The detectors measure the number of target radiation emitted by the ore sample 404, thereby determining the ore grade analysis result based on the target radiation count.
[0071] Because the fluence rate of neutrons or photons emitted by the second radiation source fluctuates and its precise value cannot be determined, and because each ore sample contains different types of elements, the absorption rate of the target radiation varies from ore sample to ore sample, thus affecting the fourth detection efficiency of the ore sample. The uncertainty of the fourth detection efficiency and the uncertainty of the fluence rate of neutrons or photons emitted by the second radiation source pose significant challenges to the accurate analysis of ore grade. Traditional techniques simply place a reference plate on the lower surface of the ore sample to determine the average value of the fluence rate over a period of time. However, for the fourth detection efficiency of the ore sample, only an approximate value is preset, without a precise determination method, resulting in low accuracy of the obtained ore grade. This application, by setting a first reference plate and a second reference plate, determines the fluence rate of the second radiation source and the detection efficiency of the ore sample. Then, based on the fluence rate of the second radiation source, the detection efficiency of the ore sample, and other known parameters, the grade analysis results of the ore sample are determined, improving the accuracy of the obtained ore grade.
[0072] In the aforementioned ore grade analysis method, when no ore sample is placed in the target area, a first X-ray source is set at a first position in the target area, and a second X-ray source is set at a second position in the target area, the first detection efficiency at the first position and the second detection efficiency at the second position are determined. When an ore sample is placed in the target area and a first reference plate is set at the first position, the flux rate of the second X-ray source is determined based on the first detection efficiency. When an ore sample is placed in the target area and a second reference plate is set at the second position, the third detection efficiency of the second reference plate at the second position is determined based on the flux rate. Based on the second detection efficiency, the third detection efficiency, and the target X-ray count value of the ore sample, the grade analysis result of the ore sample is determined. By setting the first and second reference plates, the flux rate of the second X-ray source and the detection efficiency of the ore sample are determined. Furthermore, based on the flux rate of the second X-ray source, the detection efficiency of the ore sample, and other known parameters, the grade analysis result of the ore sample is determined, thus improving the accuracy of the obtained ore grade.
[0073] In one embodiment, the above-mentioned step S202, when a ore sample is placed in the target area and a first reference plate is set at the first position, determining the flux rate of the second radiation source based on the first detection efficiency, can be achieved in the following way:
[0074] When a ore sample is placed in the target area and a first reference sheet is set at the first position, the flux rate of the second radiation source is determined based on the first detection efficiency, the target ray count value of the first reference sheet, and the number of atoms participating in the reaction on the first reference sheet.
[0075] Specifically, with Figure 3 The following example illustrates the situation, based on the first detection efficiency ε. p1 The target ray count value C1 of reference film 305 and the number of atoms N1 participating in the reaction on reference film 305 are used to determine the fluence rate Φ of the second ray source, which can be expressed by the following formula:
[0076]
[0077] Where σ1 represents the reaction cross section of reference piece 305, λ1 represents the activated nuclear decay constant of reference piece 305, and t irr This indicates the irradiation duration of the second radiation source, t cool This represents the time interval t between the end of the second radiation source irradiation and the start of the detector measurement. meas This represents the measurement time of the detector, ε b1 This indicates the intensity of specific gamma rays produced by the activated nuclei in reference piece 305.
[0078] In one embodiment, S204, when an ore sample is placed in the target area and a second reference piece is set at the second position, determining the third detection efficiency of the second reference piece at the second position based on the injection rate, can be achieved in the following way:
[0079] When a ore sample is placed in the target area and a second reference sheet is set at the second position, the third detection efficiency of the second reference sheet at the second position is determined based on the flux rate, the target ray count value of the second reference sheet, and the number of atoms participating in the reaction on the second reference sheet.
[0080] Specifically, with Figure 3 Taking an example, when a ore sample is placed in the target area and a reference plate 306 is set at position 302, the third detection efficiency ε of the reference plate 306 at position 302 is determined based on the fluence rate Φ, the target ray count value C2 of the reference plate 306, and the number of atoms participating in the reaction on the second reference plate N2. p2 It can be expressed by the following relation:
[0081]
[0082] Where σ2 represents the reaction cross section of reference piece 306, λ2 represents the activated nuclear decay constant of reference piece 306, and ε b2 This indicates the intensity of specific gamma rays produced by the activated nuclei in reference piece 306.
[0083] Figure 5 This is one of the flowcharts illustrating the method for determining the grade analysis results of ore samples provided in this application embodiment. This embodiment relates to a possible implementation of how to determine the grade analysis results of ore samples based on the second detection efficiency, the third detection efficiency, and the target ray count value of the ore sample. Based on the above embodiment, such as... Figure 5 As shown, S204 above includes:
[0084] S501, based on the second detection efficiency and the third detection efficiency, determine the linear attenuation coefficient of the medium between the second reference plate and the detector for the target ray.
[0085] The linear attenuation coefficient is a physical quantity used to describe the degree to which matter attenuates radiation.
[0086] Specifically, with Figure 3 Taking the second detection efficiency ε as an example, let's illustrate this further. p20 Third detection efficiency ε p2 The linear attenuation coefficient μ of the medium between reference plate 306 and the detector for the target ray can be expressed by the following formula:
[0087]
[0088] Where, r s d represents the radius of the ore sample, d represents the distance from the location of the reference piece 305 to the detector, and h represents the height of the ore sample.
[0089] S502, based on the linear attenuation coefficient and the target ray count value of the ore sample, determine the grade analysis results of the ore sample.
[0090] Specifically, with Figure 3 Taking this as an example, the grade analysis results of the ore sample can be determined based on the product of the linear attenuation coefficient μ obtained from the above steps and the third preset coefficient, as well as the target ray count value of the ore sample.
[0091] In one embodiment, the determination of the grade analysis result of the ore sample based on the linear attenuation coefficient in S502 above can be achieved in the following way:
[0092] The grade analysis results of the ore sample are determined based on the linear attenuation coefficient, the first detection efficiency, the target ray count value of the ore sample, and the attribute information of the ore sample.
[0093] The ore sample's attribute information includes: the radius of the ore sample, the height of the ore sample, and the distance between the first position and the detector.
[0094] Specifically, with Figure 3 Taking this as an example, based on the linear attenuation coefficient μ and the radius r of the ore sample... s The grade analysis results of the ore sample are determined by the height h of the ore sample, the distance d between position 301 and the detector.
[0095] Figure 6 This is the second flowchart illustrating the method for determining ore grade analysis results provided in this application embodiment. This embodiment relates to a possible implementation of determining the ore grade analysis results based on the linear attenuation coefficient, the first detection efficiency, the target ray count value of the ore sample, and the attribute information of the ore sample. Based on the above embodiment, such as... Figure 6 As shown, the above method also includes:
[0096] S601, based on the linear attenuation coefficient, the first detection efficiency, and the attribute information of the ore sample, determine the fourth detection efficiency of the ore sample.
[0097] Specifically, with Figure 3 Taking this as an example, based on the linear attenuation coefficient μ and the radius r of the ore sample... s The fourth detection efficiency ε of the ore sample is determined by considering the height h of the ore sample, the distance d between its position 301 and the detector. pIt can be expressed by the following relation:
[0098]
[0099]
[0100]
[0101]
[0102] S602, based on the fourth detection efficiency, injection rate and target ray count value of the ore sample, determine the grade analysis results of the ore sample.
[0103] Specifically, with Figure 3 Taking the above steps as an example, the fourth detection efficiency ε is obtained as follows: p And the injection rate Φ, which determines the atomic number N of the target element in the ore sample, can be expressed by the following formula:
[0104]
[0105] Where C represents the gamma-ray count value detected by the detector in the ore sample, σ represents the reaction cross section of the ore sample, λ represents the activated nuclear decay constant of the ore sample, and ε b This indicates the intensity of gamma rays produced by activated nuclei in the ore sample.

Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.
