[0073] The following will describe the detailed implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the detailed implementation manners described herein are only for explaining and illustrating the present disclosure, and are not used to limit the present disclosure.

[0074] It should be noted that all actions of obtaining signals, information or data in the present disclosure are carried out on the premise of complying with the corresponding data protection regulations and policies of the country where the location is located, and with the authorization given by the owner of the corresponding device.

[0075] Formation principle of sandstone-type uranium deposit: Long-term stable uranium-bearing and oxygen-containing water migrates in the permeable layer, and through the oxidation-reduction reaction of the reducing components in the permeable layer, the high-valent active uranium (U 6+ ) is reduced to low-valent stable uranium (U 4+ ) and precipitates and aggregates into ore. Thus, the factors affecting sandstone-type uranium deposits mainly include various factors such as uranium source, structure, fluid, sedimentary facies, sand body characteristics, epigenetic alteration, organic matter content, groundwater dynamic system, etc.

[0076] In the related art, geological, geophysical and geochemical methods are usually combined to evaluate geological elements such as uranium source, structural conditions, sedimentary characteristics, and alteration characteristics of the work area, and to determine the prospective area of sandstone-type uranium deposits in the target area.

[0077] The inventors found that when determining the prospective area of sandstone-type uranium deposits in the target area through the related art, the exploration and evaluation cycle time is relatively long, which in turn results in low efficiency in determining the prospective area of sandstone-type uranium deposits and high cost of the determined prospective area of sandstone-type uranium deposits.

[0078] In view of this, the present disclosure provides a method, device, medium and electronic device for determining the prospective area of sandstone-type uranium deposits to solve the problems in the related art: when determining the prospective area of sandstone-type uranium deposits in the target area through the related art, the exploration and evaluation cycle time is relatively long, which in turn results in low efficiency in determining the prospective area of sandstone-type uranium deposits and high cost of the determined prospective area of sandstone-type uranium deposits.

[0079] As shown in Figure 1 the figure Figure 1 is a schematic diagram showing a method for determining a prospective area of sandstone-type uranium ore according to an exemplary embodiment of the present disclosure. Referring to Figure 1 , it includes:

[0080] S101: Determine the active uranium enrichment area of the target area, where the active uranium enrichment area is obtained from the airborne gamma energy spectrum data of the target area;

[0081] S102: Determine the airborne radioactive parameter information and remote sensing information of the active uranium enrichment area, determine the uranium migration information according to the airborne radioactive parameter information, and determine the fluid migration information according to the remote sensing information;

[0082] S103: Determine the prospective area of sandstone-type uranium ore in the target area at least based on the uranium migration information and the fluid migration information.

[0083] Through the above technical solution, first, the active uranium enrichment area of the target area is obtained from the airborne gamma energy spectrum data. Then, the airborne radioactive parameter information and remote sensing information are obtained from the active uranium enrichment area, the uranium migration information is determined according to the airborne radioactive parameter information, and the fluid migration information is determined according to the remote sensing information. Then, the prospective area of sandstone-type uranium ore in the target area can be determined according to the uranium migration information and the fluid migration information. By combining the airborne gamma energy spectrum data with the remote sensing information to determine the prospective area of sandstone-type uranium ore, the time for determining the prospective area of sandstone-type uranium ore in the target area can be reduced, thereby improving the efficiency of determining the prospective area of sandstone-type uranium ore and reducing the cost of determining the prospective area of sandstone-type uranium ore.

[0084] In order to enable those skilled in the art to better understand the method for determining the prospective area of sandstone-type uranium ore provided by the present disclosure, the above steps will be described in detail with examples below.

[0085] Exemplarily, the airborne gamma energy spectrum data can be the energy spectrum data collected by using a gamma-ray detector through a space platform. The target area can be the area range where the prospective area of sandstone-type uranium ore needs to be determined. The active uranium enrichment area can be the area in the target area where more uranium elements are concentrated.

[0086] In the disclosed embodiment, the airborne gamma spectrum data of the target area can be measured by the airborne gamma spectrum measurement system, or the airborne gamma spectrum data can be obtained by consulting relevant materials. The airborne gamma spectrum data can be used to analyze the distribution of uranium, potassium and thorium elements in the target area, as well as the total window count rate index. And by analyzing the distribution of uranium, potassium and thorium elements, it can be used to study the geological structure, mine resource potential, environmental monitoring and radiation geology in the target area. By analyzing the total window count rate, the total gamma radiation level of the surface of the target area can be reflected. Among them, the total window count rate can be the sum of the count rates of all energy windows in the airborne gamma spectrum data. And the height of the total window count rate can be used to characterize the radioactive anomalies, geological structures and radioactive contamination in the target area.

[0087] The airborne gamma ray spectrum data can then be analyzed and processed to obtain the active uranium enrichment area.

[0088] By determining the active uranium enrichment area through airborne gamma spectroscopy data, the active uranium enrichment area can be quickly determined in a large area, thereby improving the efficiency of determining the prospective areas of sandstone-type uranium deposits.

[0089] Among possible methods, the identification of active uranium enrichment areas in the target area may include:

[0090] Airborne gamma spectroscopy data to identify target areas;

[0091] Converting the data format of the airborne gamma spectrum data to obtain grid data, wherein the grid data includes a plurality of grid unit data, and each of the grid unit data includes element content information of a target active enrichment area corresponding to the grid unit data;

[0092] Calculating the active uranium content percentage corresponding to each of the grid cell data, and drawing an active uranium contour map according to the active uranium content percentage corresponding to each of the grid cell data;

[0093] The active uranium enrichment area is determined according to the active uranium contour map.

[0094] It should be understood that when converting the data format of the airborne gamma spectrum data, the airborne gamma spectrum data can be processed to obtain grid data according to the data inspection, coordinate conversion, data filtering, spectrum data correction, content conversion, leveling, full-area data statistical analysis, ratio calculation, and grid processing in the airborne gamma spectrum measurement specification. The grid data may include spatial geometric positioning information.

[0095] In the grid data, multiple grid cell data can be included, and each grid cell data includes the element content information of the target active uranium enrichment area corresponding to the grid cell data. Among them, the element content information can include potassium element content information, uranium element content information, and thorium element content information, and the target active uranium enrichment area can be the active uranium enrichment area corresponding to the grid cell data.

[0096] After that, the proportion content of the active uranium corresponding to the grid cell data can be calculated according to the grid cell data. By calculating all the grid cell data, multiple proportion contents of the active uranium can be obtained. Among them, one grid cell data corresponds to one proportion content of the active uranium. According to the multiple proportion contents of the active uranium, an active uranium isopleth map can be drawn through geographic information system software. Then, the numerical sizes presented on the active uranium isopleth map can be analyzed to obtain the active uranium enrichment area. Among them, the data of the active uranium isopleth map includes positive data and negative data. When the data of the active uranium isopleth map is positive data, it can represent the proportion of this area providing active uranium to other areas. When the data of the active uranium isopleth map is negative data, it can represent that this area has received the later enrichment of uranium, and the smaller the negative data, the more active uranium content this area has enriched.

[0097] For example, when the element content information includes potassium element content information, uranium element content information, and thorium element content information, the proportion amount of the active uranium can be calculated according to the two different chemical activities of the uranium element and the thorium element. Among them, the uranium element has strong activity in the oxidation state and is easily transported and migrated, and is relatively stable in the reduction state; the thorium element has stable chemical properties and is not easily migrated. The proportion content of the active uranium can be calculated through the following calculation formula.

[0098] Hu = Gui - Ui

[0099] Gui = Thi × (U / Th)i

[0100] Among them, Hu can be the proportion content of the active uranium, Gui can be the content of the initial uranium element corresponding to the grid cell data, Thi can be the thorium element content corresponding to the grid cell data, Ui can be the uranium element content corresponding to the grid cell data, and (U / Th)i is the ratio of the uranium element to the thorium element of the geological unit corresponding to the grid cell data.

[0101] After that, an active uranium isopleth map can be drawn according to the calculated multiple proportion contents of the active uranium.

[0102] For example, as Figure 2 shown, for Figure 2Analysis shows that the range of negative data presented in Area A of the target area is the widest and the color is the darkest. Therefore, it can be concluded that Area A can be the enriched area of uranium in the target area.

[0103] By obtaining the airborne gamma-ray spectrometry data, the efficiency of determining the enriched area of uranium in the target area can be improved, thereby reducing the cycle of determining the prospective area of sandstone-type uranium deposits in the target area and improving the efficiency of determining the prospective area of sandstone-type uranium deposits.

[0104] For example, after obtaining the enriched area of uranium, the airborne radioactive parameter information and remote sensing information can be determined according to the enriched area of uranium. Among them, the remote sensing information can be based on airborne hyperspectral remote sensing information or satellite hyperspectral remote sensing information, and can be measured by high-resolution optical remote sensing satellites. The airborne radioactive parameter information can include uranium abundance index information and uranium migration enrichment coefficient information. Among them, the uranium abundance index information can be used to characterize the abundance and superimposed enrichment state of uranium elements in the original state of the enriched area of uranium, and the uranium migration enrichment coefficient information can be used to characterize the situation of uranium elements migrating and enriching in the enriched area of uranium under geochemical action.

[0105] In a possible way, the airborne radioactive parameter information for determining the enriched area of uranium includes:

[0106] Determine the potassium content information, thorium content information and uranium content information corresponding to each grid cell data in the enriched area of uranium;

[0107] According to the potassium content information, thorium content information and uranium content information corresponding to each grid cell, determine the uranium abundance index information and uranium migration enrichment coefficient information;

[0108] Combine the uranium abundance index information and the uranium migration enrichment coefficient information into the airborne radioactive parameter information.

[0109] It should be understood that in the enriched area of uranium, there are multiple grid cell data, and each grid cell data can include potassium content information, thorium content information and uranium content information. Uranium is a relatively active element, and its chemical activity properties are the same under oxidation conditions and reduction conditions. Therefore, the uranium abundance index information and uranium migration enrichment coefficient information can be calculated based on the potassium content information, uranium content information and thorium content information.

[0110] The uranium abundance index information can be expressed by the following calculation formula.

[0111] Ua = U × K / Th

[0112] Among them, Ua can be the uranium abundance index information, U can be the uranium content information, K can be the potassium content information, and Th can be the thorium content information.

[0113] The uranium migration enrichment coefficient information can be expressed by the following calculation formula.

[0114] Uc = U × (U / Th) × (U / K)

[0115] Among them, Uc can be the uranium migration enrichment coefficient information.

[0116] After that, the airborne radioactive parameter information can be processed to obtain the uranium migration information, and the remote sensing information can be processed to obtain the fluid migration information.

[0117] In a possible way, according to the airborne radioactive parameter information, the uranium migration information is determined, including:

[0118] According to the uranium abundance index information in the airborne radioactive parameter information, determine the uranium abundance index isoline map of the active uranium enrichment area;

[0119] According to the uranium migration enrichment coefficient information in the airborne radioactive parameter information, determine the uranium migration enrichment coefficient isoline map of the active uranium enrichment area;

[0120] According to the uranium abundance index isoline map and the uranium migration enrichment coefficient isoline map, determine the uranium migration information.

[0121] It should be understood that as Figure 3 shown, Figure 3 is a schematic diagram of the uranium abundance index information shown according to an exemplary embodiment of the present disclosure. The uranium abundance index isoline map can be drawn in the geographic information system software according to the uranium abundance index information; thus, in Figure 3 , the numerical value shown in its lower left corner area can represent the specific value of the uranium element enriched corresponding to each color in the active uranium enrichment area. The larger the numerical value, the more uranium elements are enriched in this area. Thus, it can be obtained that the uranium elements enriched in area B1 and area B2 in the active uranium enrichment area are more than those in other areas.

[0122] As Figure 4 shown, Figure 4 is a schematic diagram of the uranium migration enrichment coefficient information shown according to an exemplary embodiment of the present disclosure. The uranium migration enrichment coefficient isoline map can be drawn in the geographic information system software according to the uranium migration enrichment coefficient information. In Figure 4Among them, the value displayed in the lower left corner area can represent the specific value of the migration of uranium elements within the enriched area of active uranium. The larger the value, the greater the probability of uranium element migration in this area. Thus, it can be obtained that in areas B1 and B2 within the enriched area of active uranium, the probability of uranium element migration is greater than that in other areas.

[0123] Thus, it can be based on Figure 3 and Figure 4 to obtain that within the enriched area of active uranium, the migration directions of active uranium can include migrating from the northwest to the southeast as shown by arrow a, migrating from the northeast to the southwest as shown by arrow b, and migrating from the east to the west as shown by arrow c.

[0124] In a possible manner, based on remote sensing information, determine fluid migration information, including:

[0125] Conduct remote sensing geological interpretation and processing on the remote sensing information to obtain remote sensing geological interpretation information;

[0126] Extract the mineral information of the remote sensing information to obtain target mineral information;

[0127] Overlay the remote sensing geological interpretation information and the target mineral information to obtain fluid migration information.

[0128] It should be understood that remote sensing geological interpretation and processing can be to extract and interpret geological information from remote sensing information through remote sensing technology. Extracting the mineral information of remote sensing information can be the process of obtaining surface mineral information using remote sensing information. Target mineral information can be the specific mineral information covered in the enriched area of active uranium. This mineral information can include trivalent iron minerals, carbonate minerals, and clay minerals, such as minerals like hematite, limonite, calcite, dolomite, kaolinite, sericite, chlorite, etc.

[0129] In the embodiments of the present disclosure, geological interpretation can be performed on the remote sensing information to obtain remote sensing geological interpretation information of the enriched area of active uranium. Among them, this remote sensing geological interpretation information can be rock stratum information and fault structure information. Then, data processing such as radiometric correction, geometric correction, atmospheric correction, and spectral reconstruction can be sequentially performed on the remote sensing information to obtain a surface emissivity dataset of the enriched area of active uranium. Then, the mineral information in this surface emissivity dataset can be extracted to obtain target mineral information. The target mineral information and the remote sensing geological interpretation information can be overlaid, and fluid migration information can be obtained based on the overlaid information.

[0130] For example, as Figure 3 and Figure 4 shown, in Figure 3 and Figure 4In the lower right corner of [the figure], each type of mineral represents a different color and can be obtained from this figure. The mineral information in the upper left corner area of region B1 is mainly limonite, calcite, and chlorite. Region C in this figure includes area C1 and area C2. The mineral information at area C1 is mainly limonite, hematite, and kaolinite, and the mineral information at area C2 is mainly limonite, hematite, calcite, and dolomite. Thus, the mineral assemblage in region C2 reflects the fluid characteristics of weak alkalinity and redox transition, and the mineral assemblage in region C1 reflects the fluid characteristics of acidity and oxidation. Based on the fluid property characteristics, analyzing regions C1 and C2, it can be obtained that the fluid in this region flows from section C1 to section C2. Since uranium elements are prone to precipitation and enrichment in the redox transition and weak alkaline environment, the fluid migration information can be from region C1 to region C2.

[0131] Through the isogram of uranium abundance index and the isogram of uranium migration enrichment coefficient in the airborne radioactive parameter information, the uranium migration information can be determined. According to the remote sensing information, the fluid migration information can be determined. Then, this uranium migration information and fluid migration information can be applied to determine the prospective area of sandstone-type uranium deposits, thereby improving the accuracy of determining the prospective area of sandstone-type uranium deposits.

[0132] For example, in the embodiments of the present disclosure, in the active uranium enrichment area, the uranium migration information can be Figure 4 the direction information indicated by arrow a, arrow b, and arrow c in [the figure], and the fluid migration information can be Figure 4 from region C1 to region C2 in [the figure]. Thus, since the directions of this uranium migration information and fluid migration information are consistent, area E in the active uranium enrichment area can be determined as the prospective area of sandstone-type uranium deposits.

[0133] By determining the prospective area of sandstone-type uranium deposits according to the uranium migration information and fluid migration information, the time for determining the prospective area of sandstone-type uranium deposits in the target area can be shortened, thereby improving the efficiency of determining the prospective area of sandstone-type uranium deposits and reducing the cost of determining the prospective area of sandstone-type uranium deposits.

[0134] In a possible manner, determining the prospective area of sandstone-type uranium deposits in the target area at least according to the uranium migration information and the fluid migration information includes:

[0135] When the migration direction characterized by the uranium migration information is consistent with the migration direction characterized by the fluid migration information, the target front area along the migration direction in the active uranium enrichment area is determined as the prospective area of sandstone-type uranium deposits.

[0136] It should be understood that when the uranium migration direction characterized by the uranium migration information in the same area is consistent with the migration direction characterized by the fluid migration information, it can represent that uranium element migration has occurred in this area. Thus, in this active uranium enrichment area, when the migration direction characterized by the uranium migration information is consistent with the migration direction characterized by the fluid migration information, the target front area of the migration direction characterized by this fluid migration information can be determined as the prospective area for sandstone-type uranium deposits. Among them, the target front area can be the direction in which the uranium migration enrichment coefficient information decreases and the front of the mineral assemblage zoning information reflecting the properties of the redox transitional fluid.

[0137] By determining the prospective area for sandstone-type uranium deposits according to the migration direction characterized by the fluid migration information when the uranium migration information is consistent with the fluid migration information, the cycle of determining the prospective area for sandstone-type uranium deposits in the target area can be shortened, thereby improving the efficiency of determining the prospective area for sandstone-type uranium deposits and reducing the cost of determining the prospective area for sandstone-type uranium deposits.

[0138] In a possible way, the determination method further includes:

[0139] Determine the geological data information of the active uranium enrichment area;

[0140] Said determining the prospective area for sandstone-type uranium deposits in the target area at least according to the uranium migration information and the fluid migration information includes:

[0141] Determine the prospective area for sandstone-type uranium deposits according to the geological data information, the uranium migration information and the fluid migration information.

[0142] It should be understood that the geological data information may include the geological information on the surface within the area of this region, and this geological information may include information such as sandstone, mudstone, faults and uranium mineralization anomalies. In the actual area corresponding to the active uranium enrichment area, the geological data of this actual area can be extracted through field geological profiles and gamma-ray spectrometry profiles to obtain the geological data information.

[0143] After obtaining the geological data information, the prospective area for sandstone-type uranium deposits can be determined according to this geological data information, the uranium migration information and the fluid migration information. Among them, according to this geological data information, it can be judged whether uranium element migration has occurred on the corresponding surface.

[0144] As Figure 5 shown, Figure 5It is a schematic diagram of geological data information from area B to area B' in the active uranium enrichment area. From this diagram, it can be obtained that in the geology from area B to area B', there are granodiorite, gravel-bearing coarse sandstone, sandstone, mudstone and Quaternary in sequence. Among them, uranium element mineralization and anomalies occur in the gravel-bearing coarse sandstone, sandstone and mudstone. Then it can be represented that in the active uranium enrichment area, in the migration direction of uranium migration information characterization, during the migration process of uranium in permeable sandstone, redox reaction occurs with the upper mudstone, and uranium precipitation occurs at the bottom of the mudstone.
