Description

Technical Field

[0001] This application relates to the field of sulfur mineral exploration, specifically to a method and apparatus for exploring sulfide ore bodies, electronic equipment, and computer-readable storage medium. Background Technology

[0002] Geophysical exploration plays a crucial role in the exploration of deep ore bodies, serving as an important means of obtaining subsurface geological information. By studying changes in geophysical fields, such as gravity, magnetism, and electric fields, it is possible to infer the subsurface geological structure and the distribution of ore bodies, providing key clues for mineral exploration.

[0003] Induced polarization (IP) instruments are important equipment in geophysical exploration, mainly used to detect the conductivity and induced polarization characteristics of underground geological bodies in order to locate metal ore bodies. However, they are often very large, containing complex circuit systems, high-power transmitting devices, and other components, making the overall size of the equipment large and extremely inconvenient to transport.

[0004] Gravimeters infer the uneven distribution of underground materials by measuring changes in the Earth's gravitational field, thereby locating potential mineral deposits. While some high-precision gravimeters can provide relatively accurate data, their size is also considerable, with internal components such as precision gravity sensors and data processing units occupying a significant amount of space.

[0005] Magnetometers utilize changes in the Earth's magnetic field to detect underground magnetic mineral deposits, such as iron and nickel ore. Traditional magnetometers, especially those used for deep ore body exploration, suffer from large size and high power consumption. To improve detection sensitivity and accuracy, magnetometers are typically equipped with high-performance magnetic sensors and signal amplification and processing circuitry, which increases the device's power consumption.

[0006] The large size, high energy consumption, and difficulties in transportation and deployment of the aforementioned exploration equipment have severely hampered the exploration of deep ore bodies. These limitations not only result in extremely low exploration efficiency but also consume a significant amount of manpower, resources, and time, leading to persistently high exploration costs. Summary of the Invention

[0007] In view of this, it is necessary to provide a method and apparatus for exploring sulfide ore bodies, electronic equipment and computer-readable storage medium, so as to achieve the technical effect of lower cost and higher exploration efficiency.

[0008] To achieve the aforementioned technical effects, firstly, this application provides a method for exploring sulfide ore bodies, including: Atmospheric parameters of the exploration area and the background area are obtained respectively. The atmospheric parameters include at least one of atmospheric aerosol optical thickness, atmospheric aerosol light scattering coefficient and atmospheric aerosol particle number concentration. The atmospheric parameters of the exploration area and the atmospheric parameters of the background area are time-aligned, and the atmospheric parameter difference between the atmospheric parameters of the exploration area and the atmospheric parameters of the background area is calculated. The presence of sulfide ore bodies in the exploration area is determined based on the difference in atmospheric parameters.

[0009] In one possible embodiment, the atmospheric parameters include the atmospheric aerosol optical thickness, the atmospheric parameters of the exploration area include the probe atmospheric aerosol optical thickness, and the atmospheric parameters of the background area include the background atmospheric aerosol optical thickness.

If the target thickness difference is greater than the thickness difference threshold and the target Estrand wavelength index is greater than the preset index threshold, it is determined that the sulfide ore body exists in the exploration area. If the target Estrand wavelength index is less than or equal to the preset index threshold, it is determined that the sulfide ore body does not exist in the exploration area.

[0011] In one possible embodiment, the atmospheric parameters include the atmospheric aerosol particle number concentration, the atmospheric parameters of the exploration area include the detected atmospheric aerosol particle number concentration, and the atmospheric parameters of the background area include the background atmospheric aerosol particle number concentration. The calculation of the atmospheric parameter difference between the atmospheric parameters of the exploration area and the atmospheric parameters of the background area includes: The target concentration difference between the detected atmospheric aerosol particle number concentration and the background atmospheric aerosol particle number concentration is calculated. The step of determining whether a sulfide ore body exists in the exploration area based on the atmospheric parameter difference includes: If the target concentration difference is greater than the concentration difference threshold, it is determined that the sulfide ore body exists in the exploration area; if the target concentration difference is less than or equal to the concentration difference threshold, it is determined that the sulfide ore body does not exist in the exploration area.

[0012] In one possible embodiment, calculating the target concentration difference between the detected atmospheric aerosol particle number concentration and the background atmospheric aerosol particle number concentration includes: The detection particle size concentration of the atmospheric aerosol particle number concentration within the preset particle size range is obtained, and the background atmospheric aerosol particle number concentration within the preset particle size range is obtained. Calculate the first concentration difference between the detected particle size concentration and the background particle size concentration, and calculate the second concentration difference between the detected atmospheric aerosol particle number concentration and the background atmospheric aerosol particle number concentration; The step of determining whether a sulfide ore body exists in the exploration area based on the atmospheric parameter difference also includes: The target concentration ratio of the first concentration difference and the second concentration difference is calculated. If the target concentration difference is greater than the concentration difference threshold and the target concentration ratio is greater than the concentration ratio threshold, it is determined that the sulfide ore body exists in the exploration area. If the target concentration ratio is less than or equal to the concentration ratio threshold, it is determined that the sulfide ore body does not exist in the exploration area.

[0013] In one possible embodiment, the atmospheric parameters include the atmospheric aerosol light scattering coefficient, the atmospheric parameters of the exploration area include the detected atmospheric aerosol light scattering coefficient, and the atmospheric parameters of the background area include the background atmospheric aerosol light scattering coefficient. The calculation of the atmospheric parameter difference between the atmospheric parameters of the exploration area and the atmospheric parameters of the background area includes: The difference between the target scattering coefficient and the background atmospheric aerosol light scattering coefficient is calculated. The step of determining whether a sulfide ore body exists in the exploration area based on the atmospheric parameter difference includes: If the difference in the target scattering coefficients is greater than the scattering coefficient difference threshold, it is determined that the sulfide ore body exists in the exploration area; if the difference in the target scattering coefficients is less than or equal to the scattering coefficient difference threshold, it is determined that the sulfide ore body does not exist in the exploration area.

[0014] In one possible embodiment, the atmospheric parameters include the atmospheric aerosol optical thickness, the atmospheric aerosol light scattering coefficient, and the atmospheric aerosol particle number concentration; The calculation of the atmospheric parameter difference between the atmospheric parameters of the exploration area and the atmospheric parameters of the background area includes: Calculate the target thickness difference of the atmospheric aerosol optical thickness, the target scattering coefficient difference of the atmospheric aerosol light scattering coefficient, and the target concentration difference of the atmospheric aerosol particle number concentration, respectively. The target thickness difference, the target scattering coefficient difference, and the target concentration difference are weighted and summed based on the set weights to obtain a weighted sum value; If the weighted sum is greater than a preset sum threshold, it is determined that the sulfide ore body exists in the exploration area; if the weighted sum is less than or equal to the preset sum threshold, it is determined that the sulfide ore body does not exist in the exploration area.

[0015] Secondly, this application provides a sulfide ore body exploration apparatus, comprising: The detection module is used to acquire atmospheric parameters of the exploration area and atmospheric parameters of the background area. The detection module includes at least one of an atmospheric aerosol optical thickness detection device, an atmospheric aerosol light scattering coefficient detection device, and an atmospheric aerosol particle number concentration detection device. The data processing module is used to perform time alignment on the atmospheric parameters of the exploration area and the atmospheric parameters of the background area, and calculate the atmospheric parameter difference between the atmospheric parameters of the exploration area and the atmospheric parameters of the background area. The result output module is used to determine whether there is a sulfide ore body in the exploration area based on the atmospheric parameter difference.

[0016] Thirdly, this application also provides an electronic device, including a memory and a processor, wherein, The memory is used to store programs; The processor, coupled to the memory, is used to execute the program stored in the memory to implement the steps in the sulfide ore body exploration method described in any of the above implementations.

[0017] Fourthly, this application also provides a computer-readable storage medium for storing a computer-readable program or instructions, which, when executed by a processor, can implement the steps in the sulfide ore body exploration method described in any of the above implementations.

[0018] The beneficial effects of this application are: Compared with related technologies, the sulfide ore body exploration method, apparatus, electronic equipment, and computer-readable storage medium provided in this application include setting a background area corresponding to the exploration area where sulfide ore body exploration is required. Atmospheric parameters of both the exploration area and the background area are acquired. The atmospheric parameters of the exploration area and the background area are time-aligned, and the atmospheric parameter difference between them is calculated. The presence of sulfide ore bodies in the exploration area is determined based on this difference. By comparing and calculating the difference between the atmospheric parameters of the exploration area and the background area, the existence of sulfide ore bodies in the exploration area is determined, resulting in higher exploration efficiency. Furthermore, since only atmospheric parameters such as atmospheric aerosol optical thickness, atmospheric aerosol light scattering coefficient, and atmospheric aerosol particle number concentration in the exploration area and the background area need to be detected, large-scale exploration equipment is not required, thereby significantly reducing exploration costs and achieving a lower-cost and higher-efficiency technical effect.

Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0023] The terms "first," "second," etc., used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a technical feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0024] In this document, the term "embodiment" means that a particular feature, architecture, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] This application provides a method and apparatus for exploring sulfide ore bodies, an electronic device, and a computer-readable storage medium, which are described below.

[0026] Please refer to Figure 1The sulfide orebody exploration method provided in this application includes: Step S101: Obtain the atmospheric parameters of the exploration area and the atmospheric parameters of the background area respectively.

[0027] In this step, the exploration area is the region where sulfide ore bodies need to be explored, and the corresponding background area is the region where no sulfide ore bodies have been discovered. Atmospheric parameter measuring devices are set up in both the exploration area and the background area, and atmospheric parameters of the exploration area and the background area are collected within the same time period using different atmospheric parameter measuring devices.

[0028] Specifically, atmospheric parameters include at least one of atmospheric aerosol optical thickness, atmospheric aerosol light scattering coefficient, and atmospheric aerosol particle number concentration. Accordingly, the corresponding detection equipment includes a multi-band solar photometer for acquiring the aerosol optical thickness of the entire atmospheric column; a high-sensitivity turbidimeter with its inlet located near the ground surface for acquiring the light scattering coefficient of near-surface air; and a broadband particle counter with its inlet juxtaposed with the turbidimeter for acquiring the particle size distribution and number concentration of aerosols in near-surface air.

[0029] Furthermore, when detecting atmospheric parameters in the exploration area and the background area, the detection time was also recorded. For example, GPS timestamps can be used to mark the atmospheric parameters in the exploration area and the background area.

[0030] Step S102: Time-align the atmospheric parameters of the exploration area with those of the background area.

[0031] Specifically, this step involves time-aligning atmospheric parameters collected from the exploration area and the background area at different time periods, retaining only those collected within the same time period. For example, if the atmospheric parameters for the exploration area are collected from 8:00 to 16:00, and the atmospheric parameters for the background area are collected from 9:00 to 17:00, then the intersection of the 8:00 to 16:00 and 9:00 to 17:00 time periods is taken to obtain the atmospheric parameters for both the exploration area and the background area collected during the 9:00 to 16:00 time period.

[0032] Step S103: Calculate the difference between the atmospheric parameters of the exploration area and the atmospheric parameters of the background area, and determine whether there is a sulfide ore body in the exploration area based on the difference in atmospheric parameters.

[0033] In this application, different difference calculation methods are used to determine sulfide ore bodies for different atmospheric parameters. For details, please refer to... Figure 2When the atmospheric parameters include atmospheric aerosol optical thickness, the atmospheric parameters of the exploration area include the detected atmospheric aerosol optical thickness, and the atmospheric parameters of the background area include the background atmospheric aerosol optical thickness, this step S103 specifically includes: Step S201: Calculate the target thickness difference between the optical thickness of the detected atmospheric aerosol and the optical thickness of the background atmospheric aerosol.

[0034] Since the aerosols generated by sulfide ore bodies are typical "fine mode" or "accumulation mode" particles, their extinction effect on light follows the Rayleigh scattering or Mie scattering theory. Their extinction efficiency for short wavelength light (such as blue and purple) is much higher than that for long wavelength light (such as red and infrared). Therefore, this step focuses more on the optical thickness of atmospheric aerosols in the short wavelength band (200nm to 500nm).

[0035] In this step, the optical thickness of the probe atmospheric aerosol and the optical thickness of the background atmospheric aerosol are sampled using a first preset wavelength λ (the aforementioned short-wave band, specifically 440nm in this embodiment), to obtain the probe atmospheric aerosol optical thickness AOD_exploration(λ) and the background atmospheric aerosol optical thickness AOD_background(λ) at the first preset wavelength. Based on this, the target thickness difference ΔAOD(λ) = AOD_exploration(λ) - AOD_background(λ).

[0036] Step S202: Determine whether the target thickness difference is greater than the thickness difference threshold. If the target thickness difference is greater than the thickness difference threshold, proceed to step S203; if the target thickness difference is less than or equal to the thickness difference threshold, proceed to step S204.

[0037] In this step, the thickness difference threshold is a pre-set constant threshold, for example, in this embodiment, the thickness difference threshold is specifically 0.015. Alternatively, in some other embodiments of this application, the thickness difference threshold can also be determined based on the background atmospheric aerosol optical thickness, specifically: acquiring atmospheric aerosol optical thickness data of the background area over a relatively long period of time, calculating the standard deviation σ of the atmospheric aerosol optical thickness over this period of time, and using a set multiple of this standard deviation σ as the thickness difference threshold, such as 3σ, 4σ, etc.

[0038] Step S203: Determine the existence of sulfide ore bodies in the exploration area.

[0039] Step S204: Determine that there are no sulfide ore bodies in the exploration area.

[0040] It is understandable that, such as Figure 2 The illustration shown is merely a specific example of determining the presence of sulfide ore bodies in an exploration area based on atmospheric aerosol optical thickness in this embodiment. For other embodiments in this application, please refer to... Figure 3Determining the presence of sulfide ore bodies in an exploration area based on atmospheric aerosol optical thickness includes: Step S301: Calculate the target thickness difference between the optical thickness of the detected atmospheric aerosol and the optical thickness of the background atmospheric aerosol.

[0041] Step S302: Determine whether the target thickness difference is greater than the thickness difference threshold. If the target thickness difference is greater than the thickness difference threshold, proceed to step S303; if the target thickness difference is less than or equal to the thickness difference threshold, proceed to step S308.

[0042] Step S303: Obtain the first detection wavelength thickness and the second detection wavelength thickness at the first preset wavelength and the second preset wavelength, respectively.

[0043] In this step, the first preset wavelength is specifically a short-wavelength band (200nm to 500nm), and the second preset wavelength is greater than the first preset wavelength. In this embodiment, the first preset wavelength is 440nm, and the second preset wavelength is 870nm.

[0044] Step S304: Obtain the background atmospheric aerosol optical thickness at the first preset wavelength and the second preset wavelength, respectively.

[0045] Step S305: Calculate the first thickness difference between the first detection wavelength thickness and the first background wavelength thickness, calculate the second thickness difference between the second detection wavelength thickness and the second background wavelength thickness, and calculate the target Estrand wavelength index of the first thickness difference and the second thickness difference.

[0046] In this step, the specific formula for calculating the target Estrand wavelength index is as follows: α_diff=-ln[ΔAOD(440nm) / ΔAOD(870nm)] / ln(440 / 870); Wherein, ΔAOD(440nm) is the first thickness difference and ΔAOD(870nm) is the second thickness difference.

[0047] Furthermore, in addition to calculating the target Estrand wavelength index of the first thickness difference and the second thickness difference, in some other embodiments of this application, the thickness difference ratio of the first thickness difference and the second thickness difference can be directly calculated. In the subsequent step S306, it is determined whether the thickness difference ratio is greater than the ratio threshold. If yes, step S307 is executed; if no, step S308 is executed.

[0048] Step S306: Determine whether the target Estrand wavelength index is greater than the preset index threshold. If yes, proceed to step S307; otherwise, proceed to step S308.

[0049] Step S307: Confirm the existence of sulfide ore bodies in the exploration area.

[0050] Step S308: Determine that there are no sulfide ore bodies in the exploration area. It is understood that steps S301, S302, S307, and S308 in this embodiment are largely the same as steps S201 to S204 described above. For details, please refer to the specific description in the aforementioned embodiment.

[0051] Please refer to Figure 4 When atmospheric parameters include atmospheric aerosol particle number concentration, atmospheric parameters in the exploration area include the detected atmospheric aerosol particle number concentration, and atmospheric parameters in the background area include the background atmospheric aerosol particle number concentration, this step S103 specifically includes: Step S401: Calculate the target concentration difference between the detected atmospheric aerosol particle number concentration and the background atmospheric aerosol particle number concentration.

[0052] Step S402: Determine whether the target concentration difference is greater than the concentration difference threshold. If the target concentration difference is greater than the concentration difference threshold, proceed to step S403; if the target concentration difference is less than or equal to the concentration difference threshold, proceed to step S404.

[0053] Step S403: Confirm the existence of sulfide ore bodies in the exploration area.

[0054] Step S404: Determine that there are no sulfide ore bodies in the exploration area.

[0055] It is understandable that, such as Figure 4 The illustration shown is merely a specific example in this embodiment of determining the presence of sulfide ore bodies in an exploration area based on atmospheric aerosol particle number concentration. For other embodiments in this application, please refer to... Figure 5 Determining the presence of sulfide ore bodies in an exploration area based on atmospheric aerosol particle number concentration includes: Step S501: Calculate the target concentration difference between the detected atmospheric aerosol particle number concentration and the background atmospheric aerosol particle number concentration.

[0056] Step S502: Determine whether the target concentration difference is greater than the concentration difference threshold. If the target concentration difference is greater than the concentration difference threshold, proceed to step S403; if the target concentration difference is less than or equal to the concentration difference threshold, proceed to step S408.

[0057] Step S503: Obtain the detection particle size concentration within the preset particle size range of the atmospheric aerosol particle number concentration, and obtain the background particle size concentration within the preset particle size range of the background atmospheric aerosol particle number concentration.

[0058] After sulfide oxidation, the sulfate aerosol generated by gas-particle conversion has a particle size mainly concentrated in the accumulation mode of 0.1μm to 1.0μm. Based on this, the preset particle size range in this step is specifically 0.1μm to 1.0μm.

[0059] Step S504: Calculate the first concentration difference between the detected particle size concentration and the background particle size concentration, and calculate the second concentration difference between the detected atmospheric aerosol particle number concentration and the background atmospheric aerosol particle number concentration.

[0060] In this step, the second concentration difference is specifically the difference between the detected atmospheric aerosol particle number concentration and the background atmospheric aerosol particle number concentration across the entire particle size range. The formula is expressed as: R_fine=ΔN(0.1-1.0μm) / ΔN(total); ΔN(d1,d2)=N_Exploration(d1,d2)-N_Background(d1,d2); Wherein, ΔN is the concentration difference, (d1,d2) is the particle size range, ΔN(0.1-1.0μm) is the first concentration difference, and ΔN(total) is the second concentration difference.

[0061] Step S505: Calculate the target concentration ratio of the first concentration difference and the second concentration difference.

[0062] Step S506: Determine whether the target concentration ratio is greater than the concentration ratio threshold. If yes, proceed to step S507; otherwise, proceed to step S508.

[0063] Step S507: Confirm the existence of sulfide ore bodies in the exploration area.

[0064] Step S508: Determine that there are no sulfide ore bodies in the exploration area.

[0065] It is understood that steps S501, S502, S507, and S508 in this embodiment are largely the same as steps S401 to S404 described above. For details, please refer to the specific description in the aforementioned embodiment.

[0066] Please refer to Figure 6 When atmospheric parameters include the atmospheric aerosol light scattering coefficient, atmospheric parameters in the exploration area include the detected atmospheric aerosol light scattering coefficient, and atmospheric parameters in the background area include the background atmospheric aerosol light scattering coefficient, this step S103 specifically includes: Step S601: Calculate the difference between the target scattering coefficient and the background atmospheric aerosol light scattering coefficient.

[0067] In this step, the light scattering coefficients of the detected atmospheric aerosols and the background atmospheric aerosols are sampled using a third preset wavelength k to obtain the light scattering coefficients of the detected atmospheric aerosols (sp_exploration(k)) and the background atmospheric aerosols (sp_background(k)) at the third preset wavelength. Based on this, the difference in target scattering coefficients Δsp(k) = sp_exploration(k) - sp_background(k).

[0068] The third preset wavelength k is specifically the wavelength within the band (300nm to 600nm) that the human eye is most sensitive to, and in this embodiment it is specifically 550nm.

[0069] Step S602: Determine whether the target scattering coefficient difference is greater than the scattering coefficient difference threshold. If the target scattering coefficient difference is greater than the scattering coefficient difference threshold, proceed to step S603; if the target scattering coefficient difference is less than or equal to the scattering coefficient difference threshold, proceed to step S604.

[0070] Step S603: Confirm the existence of sulfide ore bodies in the exploration area.

[0071] Step S604: Determine that there are no sulfide ore bodies in the exploration area.

[0072] The above describes a specific method for determining the presence of sulfide ore bodies in an exploration area when atmospheric parameters include any one of atmospheric aerosol optical thickness, atmospheric aerosol light scattering coefficient, and atmospheric aerosol particle number concentration. In some embodiments of this application, when the atmospheric parameters include all atmospheric aerosol optical thickness, atmospheric aerosol light scattering coefficient, and atmospheric aerosol particle number concentration, the method may further include: calculating the target thickness difference of atmospheric aerosol optical thickness, the target scattering coefficient difference of atmospheric aerosol light scattering coefficient, and the target concentration difference of atmospheric aerosol particle number concentration, respectively; performing a weighted summation of the target thickness difference, target scattering coefficient difference, and target concentration difference based on set weights to obtain a weighted sum value; if the weighted sum value is greater than a preset sum value threshold, it is determined that a sulfide ore body exists in the exploration area; if the weighted sum value is less than or equal to the preset sum value threshold, it is determined that no sulfide ore body exists in the exploration area.

[0073] The specific calculation formula is as follows: MAI = w1×f(ΔAOD) + w2×f(Δsp) + w3×f(ΔN) + w4×f(α_diff) + w5×f(R_fine), where w1, w2, w3, w4, and w5 are set weights, and f() is the normalization function.

[0074] In this embodiment, the set weight is a preset constant value. In some other embodiments of the present application, the set weight can also be set according to the difference between the target thickness difference, the target scattering coefficient difference, the target concentration difference, the target Ångström wavelength exponent, and the difference between the target concentration ratio and the corresponding threshold. A larger set weight is set for the quantity with a smaller difference.

[0075] Furthermore, in addition to directly determining whether there is a sulfide ore body in the exploration area based on the weighted sum value, the exploration area can also be classified according to the weighted sum value, specifically including: Level I anomaly (MAI > 0.85): Strong indication signal, regarded as a prospecting clue with extremely high potential. It is recommended to immediately conduct on-site verification.

[0076] Level II anomaly (0.6 < MAI ≤ 0.85): Medium-intensity indication, indicating a greater possibility of an anomaly source in this area, and continuous monitoring is required.

[0077] Level III anomaly (0.4 < MAI ≤ 0.6): Weak indication signal, recorded as a potential area of concern, and comprehensive judgment needs to be combined with other geological data.

[0078] Compared with the related technology, in the sulfide ore body exploration method provided by this embodiment, a background area corresponding to the exploration area where sulfide ore body exploration is required is set, the atmospheric parameters of the exploration area and the atmospheric parameters of the background area are respectively obtained, the atmospheric parameters of the exploration area and the atmospheric parameters of the background area are time-aligned, and the atmospheric parameter difference between the atmospheric parameters of the exploration area and the atmospheric parameters of the background area is calculated; whether there is a sulfide ore body in the exploration area is determined according to the atmospheric parameter difference. By comparing and calculating the difference between the atmospheric parameters of the exploration area and the atmospheric parameters of the background area, whether there is a sulfide ore body in the exploration area is determined, and the exploration efficiency is relatively high; at the same time, since only the atmospheric parameters such as the atmospheric aerosol optical thickness, the atmospheric aerosol light scattering coefficient, and the atmospheric aerosol particle number concentration of the exploration area and the background area need to be detected, without using large-scale exploration equipment, the exploration cost can be greatly reduced, achieving the technical effect of lower cost and higher exploration efficiency.

[0079] In order to better implement the sulfide ore body exploration method in the embodiments of the present application, correspondingly, based on the sulfide ore body exploration method, as Figure 7 shown, the embodiments of the present application also provide a sulfide ore body exploration device, and the sulfide ore body exploration device includes: A detection module 701, and the detection module 701 is used to obtain the atmospheric parameters of the exploration area and the atmospheric parameters of the background area.

Result output module 703 is used to determine whether there is a sulfide ore body in the exploration area based on the difference in atmospheric parameters.

[0080] Please refer to Figure 8 In this embodiment, the detection module 701 specifically includes: an atmospheric aerosol optical thickness detection device 801, an atmospheric aerosol light scattering coefficient detection device 802, and an atmospheric aerosol particle number concentration detection device 803. Specifically, the atmospheric aerosol optical thickness detection device 801 is a multi-band solar photometer, the atmospheric aerosol light scattering coefficient detection device 802 is a high-sensitivity turbidimeter, and the atmospheric aerosol particle number concentration detection device 803 is a broadband particle counter. Furthermore, the detection module 701 also includes a data acquisition and communication unit 804 for uniformly acquiring, buffering, and transmitting atmospheric parameters to the data processing module 702; a power supply unit 805, such as a solar panel and battery pack, for providing continuous power; and a meteorological unit 806 for recording auxiliary correction parameters such as wind speed, wind direction, temperature, and humidity.
