Description

[0003] Uranium resources are a kind of strategic energy mineral resources in short supply in China, and are metaphorically called the food of nuclear power plants due to their importance. With the needs of China's national defense construction and nuclear power development, the contradiction between supply and demand of domestic uranium resources is increasingly prominent. Finding and developing in-situ leaching sandstone-type uranium deposits has become the development trend of natural uranium. Sandstone-type uranium deposits are the most widely distributed type of uranium deposits in the world, and have great industrial significance. According to the statistics of 528 formed uranium deposits in the world by the International Atomic Energy Agency (1996), there are 250 sandstone-type uranium deposits, accounting for 42.9% of the total, ranking first.

[0004] Sandstone-type uranium deposits have a complete source-transport-accumulation system. The source recharge area is mainly the middle and high mountain systems around the basin. These uplifted mountain systems are subjected to surface water leaching and erosion, becoming a local recharge area for groundwater and a source recharge area. The groundwater carrying uranium-bearing minerals migrates in the strata and enriches into ore when encountering suitable ore-forming environments. During the runoff process, due to the existence of pressure reduction areas, the confined water overflows out of the surface, forming lakes and rivers in low-lying places. These low-lying places are the discharge area. The discharge area and the recharge area are the runoff area. The complete recharge-runoff-discharge system, combined with the repeated circulation of groundwater, causes uranium-bearing minerals to precipitate, enrich, and accumulate under suitable redox conditions. Therefore, it is very important to identify the recharge-discharge information of sandstone-type uranium deposits in the process of uranium exploration. SUMMARY

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0026] Figure 1 The implementation flow of the sandstone-type uranium deposit filler flow information identification method provided by the embodiment of the present invention is shown. For ease of description, only the parts related to the embodiment of the present invention are shown, and are detailed below:

[0027] like Figure 1 As shown, the method for identifying filler discharge information in sandstone-type uranium deposits includes:

[0028] Step 101: Determine the recharge area of ​​sandstone-type uranium deposits based on the spectral information of remote sensing images and / or the elevation information of digital elevation images;

[0029] Step 102, according to the remote sensing image green information and humidity information, and / or the water body information in a planar or linear distribution on the remote sensing image, the discharge area of the sandstone type uranium mine is determined;

[0030] Step 103, according to the recharge area of the sandstone type uranium mine and the discharge area of the sandstone type uranium mine, the runoff area of the sandstone type uranium mine is determined.

[0031] In the identification of the recharge and runoff information of the sandstone type uranium mine, the remote sensing image can provide the required surface information, the spectral information of the remote sensing image can include the spectral region of the uranium anomaly, and then the recharge area of the sandstone type uranium mine can be determined through the spectral information of the remote sensing image. On the other hand, the digital elevation image is a special image data, which shows the altitude of different areas. The elevation information of the digital elevation image can include mountain ranges with high altitudes, which are prominent on the ground and receive groundwater recharge. Uranium minerals are transported by leaching and carrying of groundwater, which often indicates the presence of uranium mines.

[0032] In order to improve the identification accuracy of the recharge area of the sandstone type uranium mine, the spectral region with high elevation information of the digital elevation image and uranium anomaly can be determined as the recharge area of the sandstone type uranium mine by combining the spectral information of the remote sensing image and the elevation information of the digital elevation image, so as to accurately determine and identify the recharge area of the sandstone type uranium mine.

[0033] Similarly, in the determination of the discharge area of the sandstone type uranium mine, the surface humidity is large, indicating that the groundwater is developed, and then the surface vegetation is rich (the green information is high), so the discharge area of the sandstone type uranium mine can be determined according to the green information and humidity information of the remote sensing image. In addition, the water body information in a planar or linear distribution on the remote sensing image reflects that the terrain of this part of the area is low, indicating that it is likely to be a discharge area of groundwater.

[0034] In order to improve the identification accuracy of the discharge area of the sandstone type uranium mine, the area with water body information in a planar or linear distribution on the remote sensing image and high green information and humidity information can be determined as the discharge area of the sandstone type uranium mine by combining the green information and humidity information of the remote sensing image and the water body information in a planar or linear distribution on the remote sensing image, so as to accurately determine and identify the discharge area of the sandstone type uranium mine.

[0035] Since the recharge area of the sandstone type uranium mine and the discharge area of the sandstone type uranium mine are generally runoff areas, the runoff area of the sandstone type uranium mine can be determined according to the recharge area of the sandstone type uranium mine and the discharge area of the sandstone type uranium mine.

[0036] In the embodiment of the present application, the recharge area of the sandstone-type uranium mine is determined according to the spectral information of the remote sensing image and / or the elevation information of the digital elevation image; then the discharge area of the sandstone-type uranium mine is determined according to the greenness information and humidity information of the remote sensing image and / or the information of the water bodies in a planar or linear distribution on the remote sensing image; finally, the runoff area of the sandstone-type uranium mine is determined according to the recharge area and the discharge area of the sandstone-type uranium mine. The embodiment of the present application determines the recharge area of the sandstone-type uranium mine through processing of the remote sensing image and the digital elevation image, and then determines the discharge area of the sandstone-type uranium mine based on the remote sensing image, and finally determines the runoff area of the sandstone-type uranium mine according to the recharge area and the discharge area of the sandstone-type uranium mine, so that the recharge area, the discharge area and the runoff area of the sandstone-type uranium mine can be quickly and effectively identified, and the blindness and cost of exploration are greatly reduced, and the success rate of exploration is improved.

[0037] Figure 2 Another implementation process of the sandstone-type uranium mine recharge-runoff-discharge information identification method provided by the embodiment of the present application is shown, only the parts related to the embodiment of the present application are shown for the convenience of description, and the details are as follows:

[0038] In an embodiment of the present application, in order to further improve the accuracy of the sandstone-type uranium mine recharge-runoff-discharge information identification, as shown in the above Figure 2 The method steps of the above Figure 1 The sandstone-type uranium mine recharge-runoff-discharge information identification method further includes the following steps on the basis of the above method steps:

[0039] Step 201, preprocessing the remote sensing image and / or the digital elevation image;

[0040] Step 101, determining the recharge area of the sandstone-type uranium mine according to the spectral information of the remote sensing image and / or the elevation information of the digital elevation image, including:

[0041] Step 202, determining the recharge area of the sandstone-type uranium mine according to the spectral information of the preprocessed remote sensing image and / or the elevation information of the preprocessed digital elevation image.

[0042] Before identifying the recharge area of the sandstone-type uranium mine, the remote sensing image and / or the digital elevation image can be preprocessed respectively to improve the identification accuracy of the recharge area of the sandstone-type uranium mine. The preprocessing includes tiling, atmospheric correction and cropping. Those skilled in the art can understand that the preprocessing can also include other preprocessing besides the above-mentioned tiling, atmospheric correction and cropping, such as color synthesis, and the embodiment of the present application does not particularly limit this.

[0043] In the embodiment of the present application, the remote sensing image and / or the digital elevation image are preprocessed, and then the recharge area of the sandstone-type uranium mine is determined according to the spectral information of the preprocessed remote sensing image and / or the elevation information of the preprocessed digital elevation image, which can further improve the accuracy of the sandstone-type uranium mine recharge-runoff-discharge information identification.

[0044] Figure 3 The implementation flow of step 101 in the sandstone-type uranium ore filler flow information identification method provided by the embodiment of the present invention is shown. For ease of description, only the parts related to the embodiment of the present invention are shown, and are detailed below:

[0045] In one embodiment of the present invention, in order to improve the identification accuracy of sandstone-type uranium deposit replenishment areas, such as... Figure 3 As shown, step 101 involves determining the recharge area of ​​sandstone-type uranium deposits based on the spectral information of remote sensing images and / or the elevation information of digital elevation images, including:

[0046] Step 301: Extract uranium ore alteration information from the remote sensing image based on the spectral information of the remote sensing image;

[0047] Step 302: Extract high-value areas from the digital elevation image whose elevation information is not less than the preset elevation information;

[0048] Step 303: Determine the recharge area of ​​sandstone-type uranium deposits based on the uranium ore alteration information extracted from the remote sensing image and / or the high-value areas of the digital elevation image elevation information.

[0049] When identifying the replenishment areas of sandstone-type uranium deposits, the first step is to extract uranium alteration information from the spectral information of remote sensing images. Specifically, this can be achieved through principal component analysis, ratio analysis, and other processing methods. Uranium alteration mainly includes carbonatization, hematization, pyrite formation, and clay mineralization. These minerals possess unique diagnostic spectral characteristics. Therefore, uranium anomalies can be analyzed based on the mineral composition and spectral characteristics of the rocks. Areas with uranium anomalies indicate a high probability of containing uranium deposits, potentially representing replenishment areas for sandstone-type uranium deposits. Thus, the replenishment areas of sandstone-type uranium deposits can be identified based on the extracted uranium alteration information from remote sensing images.

[0050] High-value areas in digital elevation imagery, not lower than the preset elevation information, indicate high-altitude mountain ranges. These areas protrude above the surface, are subject to erosion, and receive groundwater recharge. Uranium-bearing minerals are transported through leaching and transport by groundwater. Therefore, high-value areas in digital elevation imagery may also be areas containing uranium deposits. Thus, high-value areas in digital elevation imagery can also be used to identify recharge areas for sandstone-type uranium deposits.

[0051] The preset elevation information is preset elevation information, which can be preset by a person skilled in the art according to actual conditions and specific requirements. For example, the preset elevation information is 900 meters, or the preset elevation information is 1300 meters. A person skilled in the art can understand that the preset elevation information can also be other values except for 900 meters and 1300 meters, for example, the preset elevation information is 1100 meters, and the embodiment of the application does not make special limitations.

[0052] In order to improve the identification accuracy of the recharge area of the sandstone type uranium mine, the recharge area of the sandstone type uranium mine can be determined in combination with the uranium alteration information of the remote sensing image and the high value area of the elevation information of the digital elevation image. That is, the overlapping area of the area containing the uranium alteration information in the remote sensing image and the high value area of the elevation information of the digital elevation image is determined as the recharge area of the sandstone type uranium mine, so as to improve the identification accuracy of the recharge area of the sandstone type uranium mine.

[0053] In the embodiment of the application, the area containing the uranium alteration information of the remote sensing image can be the recharge area of the sandstone type uranium mine, the uranium alteration information of the remote sensing image is extracted according to the spectral information of the remote sensing image, the high value area of the elevation information of the digital elevation image can also be the recharge area of the sandstone type uranium mine, so the high value area of the elevation information not less than the preset elevation information in the digital elevation image is extracted, and then the recharge area of the sandstone type uranium mine is determined according to the extracted uranium alteration information of the remote sensing image and / or the high value area of the elevation information of the digital elevation image, so as to improve the identification accuracy of the recharge area of the sandstone type uranium mine.

[0054] Figure 4 The implementation process of step 102 in the method for identifying the recharge area of the sandstone type uranium mine provided by the embodiment of the application is shown, only the part related to the embodiment of the application is shown for the convenience of description, and the details are as follows:

[0055] In an embodiment of the application, in order to improve the identification accuracy of the discharge area of the sandstone type uranium mine, as shown in Figure 3 Step 102, the discharge area of the sandstone type uranium mine is determined according to the greenness information and humidity information of the remote sensing image, and / or the water body information distributed in a planar or linear shape on the remote sensing image, including:

[0056] Step 401, the remote sensing image is subjected to a tasseled cap transformation, the high value area of the greenness information not less than the preset greenness information and the high value area of the humidity information not less than the preset humidity information on the remote sensing image are extracted;

[0057] Step 402, the water body information distributed in a planar or linear shape on the remote sensing image is extracted;

[0058] Step 403, according to the high value area of the green information and the high value area of the humidity information, and / or the water body information distributed in a planar or linear manner on the remote sensing image, the discharge area of the sandstone type uranium mine is determined.

[0059] When identifying the discharge area of the sandstone type uranium mine, for the relatively concealed discharge area, the remote sensing image can be subjected to a Tasseled Cap transformation, and then the high value area of the green information (including but not limited to the greenness index, etc.) not less than the preset green information on the remote sensing image is extracted, and the high value area of the humidity information not less than the preset humidity information is extracted. The high value area of the humidity information indicates that the underground water is developed, so that the surface vegetation is rich, and the high greenness indicates that the surface vegetation is rich, which indirectly indicates that the underground humidity is large. Therefore, the high value area of the humidity information and the high value area of the green information on the remote sensing image can be the discharge area of the sandstone type uranium mine. Therefore, the discharge area of the sandstone type uranium mine can be determined and identified based on the high value area of the green information and the high value area of the humidity information on the remote sensing image.

[0060] The preset green information is a preset green information, which can be preset by a person skilled in the art according to actual conditions and specific requirements. For example, the preset green information is -50, or the preset green information is -80. It can be understood by a person skilled in the art that the preset green information can also be preset to other values other than -50 and -80, such as -70. The embodiments of the present application do not make special limitations thereto.

[0061] The preset humidity information is a preset humidity information, which can be preset by a person skilled in the art according to actual conditions and specific requirements. For example, the preset humidity information is 30% RH, or the preset humidity information is -20% RH. It can be understood by a person skilled in the art that the preset humidity information can also be preset to other values other than 30% RH and -20% RH, such as 45% RH. The embodiments of the present application do not make special limitations thereto.

[0062] In addition, the water body information distributed in a planar or linear manner on the remote sensing image, such as lakes, relatively wide rivers, water bubbles, etc. These areas are low-lying, which are relatively direct discharge areas of underground water. These areas can be the discharge area of the sandstone type uranium mine, which is suitable for the desert gobi area and the water body developed area. Therefore, the discharge area of the sandstone type uranium mine can be determined based on the water body information distributed in a planar or linear manner on the remote sensing image.

[0063] In view of the fact that some areas have rich vegetation but no surface or linearly distributed water body information, and some areas have surface or linearly distributed water body information but no rich vegetation, in order to improve the identification accuracy of the discharge area of the sandstone-type uranium mine, the high-value area of the greenness information and the high-value area of the humidity information of the remote sensing image, and the surface or linearly distributed water body information on the remote sensing image can be combined to determine the discharge area of the sandstone-type uranium mine, that is, the area or region that contains both the surface or linearly distributed water body information on the remote sensing image and the high-value area of the greenness information and the high-value area of the humidity information is used to accurately determine the discharge area of the sandstone-type uranium mine, thereby improving the identification accuracy of the discharge area of the sandstone-type uranium mine.

[0064] In the embodiment of the present application, the high-value area of the greenness information and the high-value area of the humidity information on the remote sensing image indicate that the groundwater is developed, so the remote sensing image is subjected to a tasseled cap transformation, the high-value area of the greenness information not less than the preset greenness information and the high-value area of the humidity information not less than the preset humidity information on the remote sensing image are extracted, the surface or linearly distributed water body information on the remote sensing image also reflects the discharge area of the sandstone-type uranium mine, so the surface or linearly distributed water body information on the remote sensing image is extracted, and then the discharge area of the sandstone-type uranium mine is determined according to the high-value area of the greenness information and the high-value area of the humidity information and / or the surface or linearly distributed water body information on the remote sensing image, thereby improving the identification accuracy of the discharge area of the sandstone-type uranium mine.

[0065] The present application combines the remote sensing image and the digital elevation image to effectively and quickly identify the recharge area, discharge area and runoff area of the sandstone-type uranium mine. In addition, the direct and hidden discharge areas are effectively identified for different regions, such as vegetation-covered regions or desert bare regions.

[0066] The embodiment of the present application also provides a device for identifying the recharge, runoff and discharge information of the sandstone-type uranium mine, as described in the following embodiment. Since the principles of these devices for solving problems are similar to the method for identifying the recharge, runoff and discharge information of the sandstone-type uranium mine, the implementation of these devices can be referred to the implementation of the method, and the repeated parts will not be described herein.
