Description

Technical Field

[0001] The present application relates to the field of geochemistry, and in particular to a method, device, electronic equipment and medium for verifying geochemical anomalies in vegetation-covered areas. Background Art

[0002] Regional geochemical exploration (abbreviated as: regional geochemical exploration) technology is an important technology in the field of mineral exploration. In the field of mineral exploration, regional geochemical exploration technology gradually realizes the targeted delineation of minerals through geochemical anomaly detection, geochemical anomaly data processing, geochemical anomaly verification and evaluation.

[0003] In the process of mineral exploration, if a certain geochemical index in natural materials is significantly different from other geochemical backgrounds, it is called geochemical anomaly (or geochemical anomaly), and the area where geochemical anomaly occurs is called geochemical anomaly area. In theory, it is believed that there is no prospecting significance in the area outside the geochemical anomaly area, and the prospecting target points are basically located in the geochemical anomaly area, but not all geochemical anomalies have one or several mines corresponding to them, and not every geochemical anomaly can find the corresponding ore deposit. Therefore, usually after obtaining the geochemical anomaly data, it is necessary to conduct geochemical anomaly verification work to further verify the geochemical anomaly and determine whether the geochemical anomaly is the target point of prospecting.

[0004] In the existing verification process of geochemical anomalies, after determining the area corresponding to the geochemical anomaly data, sampling is usually carried out in the corresponding area to determine whether there is an anomaly at present, or the anomaly is determined by trenching. Trenching is to open a trench with a width of one meter in a preset area, and through the analysis of the material in the trench, it is determined whether there is a mineral (material) body for verification.

[0005] However, in areas covered by forest vegetation, the surface is covered by a large amount of humus layers, the bedrock is exposed or even scarce, and if trenching is used directly, it is easy to miss mineral (material) bodies that cannot be detected by trenching. In order to reduce the number of missed areas, related technologies often require large-scale excavation of the vegetation cover layer, but the work is not easy to carry out and the efficiency is too low, and the effect is not satisfactory. Summary of the invention

[0006] In order to reduce the probability of missing verification in geochemical anomaly verification work, the present application provides a method, device, electronic equipment and storage medium for geochemical anomaly verification in vegetation-covered areas.

[0007] In the first aspect, the present application provides a method for verifying geochemical anomalies in vegetation-covered areas, which adopts the following technical solution:

[0008] A method for verifying geochemical anomalies in vegetation-covered areas, comprising:

[0009] Obtain geochemical anomaly data that characterizes the element types, element contents, and distribution locations of all abnormal elements in the forest area;

[0010] Dividing the geochemical anomaly data into ranges according to element types and distribution positions to generate at least one element anomaly region;

[0011] According to the element content and distribution position in each element abnormal region, the abnormal concentration center corresponding to each element abnormal region is determined respectively.

[0012] Determine the abnormal trend and at least one transverse point slot position corresponding to each of the element abnormal regions, wherein the abnormal trend passes through the abnormal concentration center;

[0013] Wherein, the transverse point slot positions are the positions of the point slots arranged at preset intervals along the abnormal direction;

[0014] Obtain verification results of each horizontal point and slot position in each of the element anomaly areas. If the verification results of all horizontal point and slots in the same element anomaly area are all no-ore results indicating no ore, then determine the abnormal vertical direction and at least one longitudinal point and slot position corresponding to the element anomaly area based on the abnormal trend.

[0015] By adopting the above technical scheme, the acquired geochemical anomaly area is first divided into multiple element anomaly areas according to the element types and the distribution positions of various elements. Each element anomaly area will be verified separately. According to the element content and distribution position corresponding to each sampling point in the element anomaly area, the anomaly trend representing the geological change is determined. According to the anomaly trend, horizontal point slots are opened in sequence for verification. When the verification results at the horizontal point slot positions are all no-ore results representing no mineral (chemical) body, the direction perpendicular to the anomaly trend, i.e., the anomaly vertical direction, is determined, and a longitudinal point slot is opened in the anomaly vertical direction. Verification is performed again at the longitudinal point slot position. According to the distribution of elements in the element anomaly area, a more efficient verification direction is provided for the verification work, which improves the efficiency of the staff and reduces the omission rate.

[0016] In a possible implementation, determining the abnormal vertical direction according to the abnormal direction includes:

[0017] Determining the abnormal vertical direction according to the abnormal trend and the abnormal concentration center;

[0018] The anomaly vertical direction is perpendicular to the anomaly strike and intersects at the anomaly concentration center.

[0019] By adopting the above technical solution, the vertical direction of the anomaly intersects with the anomaly strike and the anomaly concentration center, and verification work is carried out based on the anomaly concentration center. The anomaly concentration center represents a point with a higher element content. Verification work is carried out around this point, which is equivalent to carrying out verification work around the location with the greatest possibility of the existence of mineral (ization) bodies, which is more efficient.

[0020] In a possible implementation, the abnormal vertical direction is determined according to the abnormal trend and the abnormal concentration center, and the abnormal vertical direction is perpendicular to the abnormal trend and intersects at the abnormal concentration center, and the method further includes:

[0021] Obtaining the element content detected by each of the transverse point grooves;

[0022] Determine whether the element content corresponding to the abnormal concentration center is greater than the element content corresponding to each lateral point groove;

[0023] If yes, the abnormal concentration center is used as the intersection of the abnormal vertical direction and the abnormal trend to determine the abnormal vertical direction;

[0024] If not, determine the transverse point slot with the largest element content among the transverse point slots, take the transverse point slot with the largest element content as the intersection of the abnormal vertical direction and the abnormal strike, and determine the abnormal vertical direction.

[0025] By adopting the above technical solution, the position of the horizontal point groove with the largest element content in the horizontal point groove is taken as the intersection of the abnormal trend and the abnormal vertical direction, which is more conducive to improving the efficiency of the verification work.

[0026] In a possible implementation, determining the abnormal trend corresponding to the element abnormal area includes:

[0027] According to the element contents corresponding to all abnormal elements in the element abnormal area, each abnormal element whose element contents are in the same preset interval value is regarded as an abnormal equal value element group;

[0028] Determine the abnormal contour lines corresponding to each abnormal equal-value element group according to the distribution positions corresponding to all abnormal elements in each abnormal equal-value element group;

[0029] The abnormal trend corresponding to the element abnormal area is determined according to the abnormal concentration center and each of the abnormal contour lines.

[0030] By adopting the above technical scheme, using the element contents measured at each sampling point in the element anomaly area, the abnormal elements corresponding to the element contents in the same preset interval value are taken as a group of abnormal equivalent element groups, and the abnormal elements in another same preset interval value are taken as another group of abnormal element groups, all abnormal elements are grouped, and the distribution positions of the abnormal elements in each abnormal equivalent element group in the geochemical map are connected in sequence to form a closed curve, which is the abnormal contour line. Each abnormal equivalent element group corresponds to an abnormal contour line. According to the density between the abnormal contour lines and the change trend of each abnormal contour line, it is convenient for the staff to determine the field distribution corresponding to the current abnormal source, and then the staff can determine the abnormal direction according to the distribution between the abnormal contour lines and the position of the abnormal concentration center, which is more convenient for the staff to carry out their work.

[0031] In a possible implementation, determining the abnormal trend according to the abnormal concentration center and each of the abnormal contour lines includes:

[0032] If there is one abnormal contour line, determine the long axis direction of the abnormal contour line, and use the long axis direction as the abnormal trend;

[0033] The major axis direction is the direction of the straight line segment with the largest distance between two points on the anomaly contour line, and the straight line segment passes through the anomaly concentration center;

[0034] If there are multiple abnormal contour lines, then,

[0035] Determine the lowest anomaly contour line farthest from the center of anomaly concentration among the anomaly contour lines;

[0036] Determine the major axis direction of the lowest anomaly contour line;

[0037] The long axis direction is taken as the abnormal trend.

[0038] By adopting the above technical scheme, the part surrounded by the abnormal contour line is the area where the possibility of the existence of mineral (ization) bodies in the element abnormal area is relatively high. When there is only one abnormal contour line, the center of abnormal concentration will be taken as the center point, and the longest long axis direction in the area surrounded by the abnormal contour line will be used as the direction of the abnormal trend, so as to improve the coverage of the area with higher possibility and indirectly reduce the verification omission rate of the staff; when there are multiple abnormal contour lines, the abnormal direction is determined according to the long axis direction of the lowest abnormal contour line farthest from the abnormal concentration center, thereby improving the coverage of the area with greater possibility of mineralization.

[0039] In a possible implementation, determining at least one transverse point slot position includes:

[0040] If there is one anomaly contour line, a transverse point slot position is set with the anomaly concentration center as the center and the anomaly strike direction, and the interval between two adjacent transverse point slot positions is a preset reference interval;

[0041] If there are multiple abnormal contour lines, the interval between each horizontal point slot position between two adjacent abnormal contour lines is determined according to the distance between two adjacent abnormal contour lines on the abnormal trend and the difference in element content between the adjacent abnormal contour lines;

[0042] The position of each transverse point groove is determined according to the interval between the positions of the transverse point grooves and the abnormal direction.

[0043] By adopting the above technical scheme, the degree of change of the element content between adjacent abnormal contour lines is first determined by the distance between two adjacent abnormal contour lines and the difference in the element content of the two adjacent abnormal contour lines. According to the degree of change of the element content, when the spacing is equal, the greater the change in the element content, the greater the possibility of the existence of a mineral (formation) body. According to the change in the element content between two adjacent abnormal contour lines, the interval between the horizontal point and slot positions is determined to reduce the possibility of omissions in verification by staff during verification.

[0044] In a possible implementation, the method further includes:

[0045] Obtain the verification results corresponding to each longitudinal point slot in the abnormal vertical direction;

[0046] If all the verification results are no mineral results, then

[0047] Taking the intersection of the abnormal trend and the abnormal vertical direction as the center, a new abnormal trend is established, and the new abnormal trend is located between the original abnormal trend and the abnormal vertical direction;

[0048] According to the new abnormal trend, the new horizontal point and groove position is determined.

[0049] By adopting the above technical scheme, when the verification result in the abnormal vertical direction is a result of no ore, in order to reduce omissions, the verification work will continue. Therefore, a new abnormal trend will be established between the abnormal trend and the abnormal vertical direction with the intersection of the two as the center, and the horizontal point and slot positions will be determined on the new abnormal trend, so that the staff can continue to carry out verification work and reduce the omission rate.

[0050] In the second aspect, the present application provides a device for verifying geochemical anomalies in vegetation-covered areas, which adopts the following technical solution:

[0051] A device for verifying geochemical anomalies in vegetation-covered areas, comprising:

[0052] A data acquisition module is used to acquire geochemical anomaly data representing the element types, element contents and distribution positions of all abnormal elements in the forest area;

[0053] A region division module, used to divide the geochemical anomaly data into ranges according to element types and distribution positions, and generate at least one element anomaly region;

[0054] A center determination module, used to determine the abnormal concentration center corresponding to each element abnormal area according to the element content and distribution position in each element abnormal area;

[0055] An abnormal trend determination module, used to determine the abnormal trend and at least one transverse point slot position corresponding to each of the element abnormal regions, wherein the abnormal trend passes through the abnormal concentration center;

[0056] Wherein, the transverse point slot positions are the positions of the point slots arranged at preset intervals along the abnormal direction;

[0057] The abnormal vertical direction determination module is used to obtain the verification results of each horizontal point and slot position in each of the element abnormality areas. If the verification results of all the horizontal point and slots in the same element abnormality area are all no-ore results indicating that there is no ore, then the abnormal vertical direction and at least one longitudinal point and slot position corresponding to the element abnormality area are determined according to the abnormal trend.

[0058] Specifically, the area division module first divides the geochemical anomaly area acquired by the data acquisition module into multiple element anomaly areas according to the element types and distribution positions of various elements. The staff will conduct verification work on each element anomaly area respectively. The anomaly trend determination module determines the anomaly trend representing the geological changes according to the element content and distribution position corresponding to each sampling point in the element anomaly area, so that the staff can open horizontal point slots in sequence according to the anomaly trend for verification. When the verification results of the horizontal point slot positions are all no-ore results representing no mineral (chemical) body, the anomaly vertical determination module determines the direction perpendicular to the anomaly trend, that is, the anomaly vertical, and opens a longitudinal point slot in the anomaly vertical direction. Verification is performed again at the longitudinal point slot position. According to the distribution of elements in the element anomaly area, a more efficient verification direction is provided for the verification work, which improves the efficiency of the staff and reduces the omission rate.

[0059] In a possible implementation, when determining the abnormal vertical direction according to the abnormal trend, the abnormal vertical direction determining module is specifically used to:

[0060] Determining the abnormal vertical direction according to the abnormal trend and the abnormal concentration center;

[0061] The anomaly vertical direction is perpendicular to the anomaly strike and intersects at the anomaly concentration center.

[0062] In a possible implementation manner, the device further includes:

[0063] A content acquisition module, used to acquire the element content detected by each of the transverse point grooves;

[0064] A judgment module, used to judge whether the element content corresponding to the abnormal concentration center is greater than the element content corresponding to each horizontal point groove;

[0065] an execution module, for determining the abnormal vertical direction by taking the abnormal concentration center as the intersection of the abnormal vertical direction and the abnormal trend;

[0066] The execution module is further used to determine the horizontal point slot with the largest element content in the horizontal point slots if no, and use the horizontal point slot with the largest element content as the intersection of the abnormal vertical direction and the abnormal trend to determine the abnormal vertical direction.

[0067] In a possible implementation, the abnormal trend determination module, when determining the abnormal trend corresponding to the element abnormal area, is specifically used to:

[0068] According to the element contents corresponding to all abnormal elements in the element abnormal area, each abnormal element whose element contents are in the same preset interval value is regarded as an abnormal equal value element group;

[0069] Determine the abnormal contour lines corresponding to each abnormal equal-value element group according to the distribution positions corresponding to all abnormal elements in each abnormal equal-value element group;

[0070] The abnormal trend corresponding to the element abnormal area is determined according to the abnormal concentration center and each of the abnormal contour lines.

[0071] In a possible implementation, when determining the abnormal trend according to the abnormal concentration center and each of the abnormal contour lines, the abnormal trend determination module is specifically used to:

[0072] If there is one abnormal contour line, determine the long axis direction of the abnormal contour line, and use the long axis direction as the abnormal trend;

[0073] The major axis direction is the direction of the straight line segment with the largest distance between two points on the anomaly contour line, and the straight line segment passes through the anomaly concentration center;

[0074] If there are multiple abnormal contour lines, determine the lowest abnormal contour line farthest from the abnormal concentration center among the abnormal contour lines;

[0075] Determine the major axis direction of the lowest anomaly contour line;

[0076] The long axis direction is taken as the abnormal trend.

[0077] In a possible implementation, when determining the position of at least one transverse point groove, the abnormal trend determination module is specifically used to:

[0078] If there is one anomaly contour line, a transverse point slot position is set with the anomaly concentration center as the center and the anomaly strike direction, and the interval between two adjacent transverse point slot positions is a preset reference interval;

[0079] If there are multiple abnormal contour lines, the interval between each horizontal point slot position between two adjacent abnormal contour lines is determined according to the distance between two adjacent abnormal contour lines on the abnormal trend and the difference in element content between the adjacent abnormal contour lines;

[0080] The position of each transverse point groove is determined according to the interval between the positions of the transverse point grooves and the abnormal direction.

[0081] In a possible implementation manner, the device further includes:

[0082] The result acquisition module is used to obtain the verification results corresponding to each longitudinal point slot in the abnormal vertical direction;

[0083] The redetermination module is used for establishing a new abnormal trend with the intersection of the abnormal trend and the abnormal vertical as the center if all the verification results are no-ore results, and the new abnormal trend is located between the original abnormal trend and the abnormal vertical; according to the new abnormal trend, determining the new horizontal point and slot position.

[0084] In a third aspect, the present application provides an electronic device, which adopts the following technical solution:

[0090] A computer-readable storage medium includes: a computer program that can be loaded by a processor and execute the above-mentioned method for verifying geochemical anomalies in vegetation-covered areas.

[0091] In summary, this application includes the following beneficial technical effects:

[0092] 1. First, the acquired geochemical anomaly area is divided into multiple element anomaly areas according to the element types and distribution positions of various elements. Each element anomaly area will be verified separately. According to the element content and distribution position corresponding to each sampling point in the element anomaly area, the anomaly trend representing geological changes is determined. According to the anomaly trend, horizontal point slots are opened in sequence for verification. When the verification results at the horizontal point slot positions are all no-ore results representing no mineral (chemical) body, the direction perpendicular to the anomaly trend, i.e., the anomaly vertical direction, is determined, and a longitudinal point slot is opened in the anomaly vertical direction. Verification is carried out again at the longitudinal point slot position. According to the distribution of elements in the element anomaly area, a more efficient verification direction is provided for the verification work, which improves the efficiency of the staff and reduces the omission rate.

[0093] 2. The part surrounded by the anomaly contour lines is the area where the possibility of the existence of mineral (formation) bodies is relatively high. When there is only one anomaly contour line, the center of anomaly concentration will be taken as the center point, and the longest long axis direction in the area surrounded by the anomaly contour lines will be used as the direction of the anomaly trend, so as to improve the coverage of the areas with higher possibility and indirectly reduce the verification omission rate of the staff; when there are multiple anomaly contour lines, the anomaly direction will be determined according to the long axis direction of the lowest anomaly contour line farthest from the anomaly concentration center, thereby improving the coverage of the areas with greater possibility of mineralization.

[0098] The following is combined with Figure 1-4 This application is described in further detail.

[0099] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0100] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0101] When prospecting for minerals in a forest, explorers will take samples at multiple preset locations in the forest. First, they will obtain samples that represent the geological conditions of the forest. Then they will analyze the types and contents of elements in the samples, and make a preliminary judgment on whether each sampling point has the possibility of a mining area. Then, they will conduct a possibility verification on the locations of the sampling points that have the possibility of mining areas. Finally, they will determine whether there is a mining area at each sampling point and the possible location of the mining area if there is a mining area. The prospectors will rely on the results of the verification to carry out the next step of development for each sampling point.

[0102] Among them, there may or may not be mining areas in a forest, and the number and types of mining areas are not uniquely determined. For example, there are gold mines and lead, silver and zinc mines in Forest A; there are only copper mines in Forest B; there are two gold mines, one lead, zinc and silver mine and one quartz mine in Forest C; there is no mining area in Forest D.

[0103] After determining that the sampling point has the possibility of a mining area, the more accurate the verification work is, the more helpful it will be for subsequent mining. Therefore, the verification of geochemical anomalies is also an indispensable part.

[0104] The present application embodiment provides a method for verifying geochemical anomalies in a vegetation-covered area, which is executed by an electronic device, referring to Figure 1 , the method comprising:

[0105] Step S101, obtaining geochemical anomaly data representing the element type, element content and distribution position of abnormal elements in a forest area.

[0106] Specifically, geochemical anomalies refer to mineral-induced anomalies related to minerals or mineralized bodies. Mineral-induced anomalies characterize abnormal characteristics caused by geological or geochemical conditions during mineralization. During the mineralization process or other geological reasons, the element composition and / or content in an area changes, and the element composition and / or content in this area will be different from that in other areas. The appearance of such characteristics indicates the existence of mineral-induced anomalies.

[0107] Generally speaking, there will be corresponding element anomalies for any mine. For example, if there is a gold mine in the forest, the gold content in the area where the gold mine is located will be greatly abnormal.

[0108] Therefore, when analyzing the sample, we first determine whether the elements in the sample are abnormal based on the two characteristics of the composition and content of the elements in the sample, and determine the element abnormality data when there is an element abnormality, where the element abnormality data is the type of element and the element content. When the element content exceeds the background upper limit, it indicates that the element is abnormal. Each element abnormality data includes the element type, element content and the geographical location corresponding to each element.

[0109] Geochemical anomaly data is the data that annotates element anomaly data in the geochemical map. The geochemical map is obtained by reducing the sampling area according to a preset scale. Each sampling point corresponds to a position in the geochemical map. After analyzing the element anomaly data corresponding to the sample, the element anomaly data is annotated in the geochemical map according to the preset rules, and the geochemical anomaly data is generated.

[0110] Among them, in a possible implementation method, the method of marking the element anomaly data in the geochemical map according to preset rules can be that different types of elements in the element anomaly data are marked with their respective corresponding colors, the content of the element can be marked in digital form, and the depth of color can also be used to reflect the amount of content; the marked position is the position of the sampling point corresponding to the geochemical map.

[0111] Step S102: Divide the geochemical anomaly data into ranges according to element types and distribution positions, and generate at least one element anomaly region.

[0112] Among them, the element type represents the type of abnormal element, such as copper, gold, and the combined element of lead, zinc and silver; the geographical location represents the location of the abnormal element in the geochemical map.

[0113] Specifically, the abnormal elements corresponding to the geochemical anomaly data may be single-element anomalies or combined-element anomalies. A single-element anomaly indicates that there is an abnormality in one element at the point, and a combined-element anomaly indicates that a group of related element contents or other parameters are combined in some form in terms of genesis or space. For example, in Forest A, there are two gold mines and one lead-silver-zinc mine; the surroundings of the corresponding gold mines will show gold element anomalies; the surroundings of the lead-silver-zinc mines will show anomalies formed by the combination of lead, silver and zinc elements.

[0114] The geochemical anomaly data include the types of various abnormal elements and their positions in the geochemical map. According to the existing positions and types of abnormal elements, the geochemical map is divided according to the corresponding positions of various abnormal elements. The number of types of abnormal elements in the geochemical anomaly data corresponds to the number of element anomaly areas generated, and each element anomaly area corresponds to each abnormal element one by one.

[0115] The probability of the existence of mineral species in the element anomaly area is generally greater than that in other locations. The next direction of mineral exploration is determined by first delineating and dividing the abnormal elements. At the same time, since the abnormal elements have been identified, combined with the background characteristics of element geochemistry and the laws of elemental spatiotemporal evolution, a preliminary guess can be made about the possible mineral species currently existing, which then facilitates giving instructions to staff during the verification process.

[0116] Step S103: Determine the abnormal concentration center corresponding to each element abnormal region according to the element content and distribution position in each element abnormal region.

[0117] Among them, the abnormal concentration center is the point with the highest element content in the corresponding element abnormal area.

[0118] Specifically, the element abnormal region is a region where abnormal elements exist. In the element abnormal region, the content of the element corresponding to each sampling point is analyzed, and the sampling point with the highest element content in the element abnormal region is taken as the abnormal concentration center.

[0119] Step S104: determine the abnormal trend and at least one horizontal point slot position corresponding to each element abnormal area.

[0120] Among them, the abnormal trend passes through the abnormal concentration center; the horizontal point slot position is the position of the point slot determined at preset intervals with the abnormal trend as the direction; the point slot is a slot opened to verify the existence of the ore body, and the horizontal point slot represents the point slot set along the abnormal trend.

[0121] Specifically, during the verification process, verification will be carried out around the abnormal concentration center. In the related technology, after the abnormal concentration center is determined, trenching will be carried out within a preset range near the sampling point where the abnormal concentration center is located for verification. Trenching is a technology for digging trenches on the surface in order to expose covered rock layers or ore bodies during geological exploration. In the related technology, when digging trenches, the bottom width of the trench is 0.6 meters, the depth is less than 3 meters, and the length is determined according to the geological conditions. Generally speaking, a trench will be dug for an abnormal concentration center to determine in depth whether there is a mine inside.

[0122] However, the abnormal concentration center is not equivalent to the abnormal source. The abnormal concentration center is the point with the highest element content among the sampling points, but it is not the point with the highest content of abnormal elements in the element abnormal area, or it does not directly represent the essential source of the abnormality. Therefore, when directly implementing trench exploration for verification, it is very easy to have mineral species but fail to detect them. If you want to improve the accuracy of trench exploration verification, on the one hand, you can adjust the width and depth of the trench by increasing the cost, but this method is inefficient and the effect is not obvious because the location of the abnormal source is unclear; on the other hand, you can select multiple locations for exploration, but the efficiency of blindly selecting locations is still low, and the risk of omission is still high.

[0123] Therefore, in order to improve the accuracy of the verification work and reduce omissions during the verification process, the embodiment of the present application will take the sampling point corresponding to the abnormal concentration center as the center during verification, determine the abnormal direction according to the distribution of abnormal elements in the element abnormal area, and then determine the implementation position of at least one horizontal point slot along the direction of the abnormal trend according to the preset interval.

[0124] The two ends of the abnormal trend are located at the boundaries of the element abnormal area. The abnormal trend is a straight line and passes through the abnormal concentration center. The horizontal point slot starts from the abnormal concentration center and opens a horizontal point slot at preset intervals at both ends. The point slot is a slot laid on site for verification. During the on-site verification process, the point slot construction is first carried out according to the abnormal trend and the implementation positions of each point slot corresponding to the abnormal trend. On the surface corresponding to each implementation position, a point slot with a width of 30~70 cm, a length of 10m~20m, and a depth of 40~90 cm will be opened. The horizontal point slots along the abnormal trend are verified step by step, which improves the accuracy and the work efficiency of the staff.

[0125] Step S105, obtaining the verification results of each horizontal point and slot position in each element anomaly area. If the verification results of all horizontal point and slots in the same element anomaly area are all no-ore results indicating no ore, then determine the abnormal vertical direction and at least one longitudinal point and slot position corresponding to the element anomaly area according to the anomaly trend.

[0126] Among them, the abnormal trend is perpendicular to the abnormal vertical direction and intersects at one point; the longitudinal point groove represents the point groove set along the abnormal vertical direction.

[0127] Furthermore, the verification result is the result of characterizing the presence or absence of ore after opening a point slot at the corresponding position on the surface and analyzing and verifying it. Each verification result corresponds to each point slot one by one, and the verification result includes the result of the presence of ore and the result of the absence of ore. If the verification result of any horizontal point slot in the element anomaly area is a result of the presence of ore, it indicates that there may be a mineral (chemical) body in the current element anomaly area, which means that the staff has found the source of the anomaly along the direction of the anomaly.

[0128] If the verification results of all the horizontal slot positions in the element anomaly area are all no-ore results, it means that the staff has not found the anomaly source in all the slots along the anomaly trend. The staff will continue to search for the anomaly source along the anomaly vertical direction in accordance with the implementation positions of all the slots in the anomaly vertical direction. The anomaly vertical direction is the direction perpendicular to the anomaly trend, and the two intersect, and then determine the implementation positions of all the longitudinal slots in the anomaly vertical direction. The longitudinal slots represent the slots opened in the anomaly vertical direction.

[0129] Among them, the abnormal trend and the abnormal vertical direction are both on the horizontal plane of the surface of the earth. On the horizontal plane of the surface of the earth, the two are perpendicular and intersect at one point.

[0130] Point slots are opened in the two directions of the anomaly strike and the anomaly vertical to search for the anomaly source. If the anomaly source is found after opening the point slot, it indicates that there is a high possibility that an ore body exists in the current element anomaly area, and mining will continue in this area in the future. Furthermore, in order to improve the accuracy, in the process of opening point slots to find the anomaly source, if mineralized alteration or mineral (material) bodies are found, the staff needs to pick up the block samples in the point slots and finally determine whether the mineral (material) body is found through testing; if the anomaly source is not found in the element anomaly area, it indicates that there is a very small possibility that an ore body exists in the current element anomaly area, and the staff needs to analyze and confirm the cause. When it is confirmed that the element anomaly is indeed caused by other reasons, it will be judged as an area without ore body.

[0131] An embodiment of the present application provides a method for verifying geochemical anomalies in a vegetation-covered area. The method first divides the acquired geochemical anomaly area into a plurality of element anomaly areas according to the element types and the distribution positions of various elements. Each element anomaly area will be verified separately. The anomaly trend representing the geological changes is determined according to the element contents and distribution positions corresponding to each sampling point in the element anomaly area. Horizontal point slots are opened in sequence according to the anomaly trend for verification. When the verification results at the horizontal point slot positions are all ore-free results representing no mineral (chemical) body, a direction perpendicular to the anomaly trend, i.e., the anomaly vertical direction, is determined. A longitudinal point slot is opened in the anomaly vertical direction. Verification is performed again at the longitudinal point slot position. According to the distribution of elements in the element anomaly area, a more efficient verification direction is provided for the verification work, thereby improving the efficiency of the staff and reducing the omission rate.

[0132] A possible implementation of the embodiment of the present application, in step S105, determining the abnormal vertical direction according to the abnormal trend includes:

[0133] The anomaly vertical direction is determined based on the anomaly strike and the anomaly concentration center; the anomaly vertical direction is perpendicular to the anomaly strike and intersects at the anomaly concentration center.

[0134] Specifically, if no mineral (material) body is detected in each horizontal point slot corresponding to the abnormal trend, in order to improve the accuracy, it is necessary to detect again in the abnormal vertical direction.

[0135] When determining the anomaly vertical direction, the anomaly vertical direction and the anomaly strike are made to intersect at the anomaly concentration center. The anomaly concentration center is the point with the highest element content. It can be considered that the possibility of the existence of mineral (formation) bodies near this point is greater than that at other locations. Therefore, the anomaly vertical direction is still extended based on the anomaly concentration center. It is more efficient to conduct longitudinal point and slot exploration and excavation along the anomaly vertical direction.

[0136] A possible implementation of the embodiment of the present application is that in step S105, according to the abnormal trend and the abnormal concentration center, the abnormal vertical direction is determined, the abnormal vertical direction is perpendicular to the abnormal trend and intersects at the abnormal concentration center, and the above also includes:

[0137] Step Sa1 (not shown in the figure), obtaining the element content detected in each transverse point groove.

[0138] Step Sa2 (not shown in the figure), judging whether the element content corresponding to the abnormal concentration center is greater than the element content corresponding to each horizontal point groove.

[0139] Step Sa3 (not shown in the figure), if yes, then the abnormal concentration center is used as the intersection of the abnormal vertical direction and the abnormal trend to determine the abnormal vertical direction. If no, then the horizontal point slot with the largest element content in the horizontal point slot is determined, and the horizontal point slot with the largest element content is used as the intersection of the abnormal vertical direction and the abnormal trend to determine the abnormal vertical direction.

[0140] Specifically, after determining the abnormal trend and the implementation position of at least one horizontal point slot on the abnormal trend, the staff will open point slots in sequence according to the implementation positions of each horizontal point slot to verify the mineral (chemical) body. During the verification process, the element content in the horizontal point slot will continue to be detected and tested to obtain the element content corresponding to each horizontal point slot. After the electronic equipment obtains the element content corresponding to each horizontal point slot, it is determined whether the element content of the abnormal concentration center is the largest among all horizontal point slots. If so, the abnormal concentration center is used as the intersection of the abnormal trend and the abnormal vertical direction to establish the abnormal vertical direction; when there is a point slot in the horizontal point slot whose element content exceeds that of the abnormal concentration center, the abnormal vertical direction will be established with the horizontal point slot as the intersection of the two. The abnormal vertical direction is traced back around the point with the highest element content and the point closest to the mineral (chemical) body is traced back, which is more conducive to improving the accuracy of detection.

[0141] A possible implementation of the embodiment of the present application is that in step S104, determining the abnormal trend corresponding to the element abnormal area includes:

[0142] Step S1041 (not shown in the figure), according to the element contents corresponding to all abnormal elements in the element abnormal region, each abnormal element whose element content is in the same preset interval value is regarded as an abnormal equal value element group.

[0143] Specifically, the abnormal trend is a straight line, and the abnormal trend takes the abnormal concentration center as the origin, and any direction can be selected along the 360° direction to be determined as the abnormal trend. The direction of the abnormal trend determines the efficiency of abnormal verification to a certain extent. In order to indicate the direction of the abnormal trend, so as to determine the direction of the abnormal trend and improve the efficiency of verification, the embodiment of the present application first determines at least one group of abnormal elements whose element contents are in the same preset interval value as an abnormal equivalent element group based on the element contents of all abnormal elements in the element abnormal area. For example: the element abnormal area includes abnormal element 1, abnormal element 2, abnormal element 3, abnormal element 4, and abnormal element 5, wherein each abnormal element is of the same type, the element content of abnormal element 1 is 50, the element content of abnormal element 2 is 53, the element content of abnormal element 3 is 40, the element content of abnormal element 4 is 44, and the element content of abnormal element 5 is 37; abnormal element 1 and abnormal element 2 are in the same preset interval, and the two abnormal elements are abnormal equivalent element group A; abnormal element 3, abnormal element 4 and abnormal element 5 are in the same preset interval, and the three abnormal elements constitute abnormal equivalent element group B.

[0144] Step S1042 (not shown in the figure): determine the abnormal contour lines corresponding to each abnormal equivalent element group according to the distribution positions corresponding to all abnormal elements in each abnormal equivalent element group.

[0145] Step S1043 (not shown in the figure), determining the abnormal trend corresponding to the element abnormal area according to the abnormal concentration center and each abnormal contour line.

[0146] Specifically, the distribution positions of each abnormal element in the abnormal isovalue element group in the geochemical map are connected in sequence to form a closed curve, which is the abnormal isovalue line, wherein the abnormal isovalue element group corresponds to the abnormal isovalue line one by one. It is worth noting that different abnormal isovalue lines will not intersect.

[0147] Reference Figure 2 , Figure 2 The element anomaly area shown includes three anomaly contour lines, namely, anomaly contour line (low), anomaly contour line (middle), and anomaly contour line (high). The anomaly contour line (low) is located in the outermost layer, surrounding the anomaly contour line (middle). The anomaly contour line (middle) is in the second layer, surrounding the anomaly contour line (high). The anomaly contour line (high) is in the innermost layer, and the anomaly concentration center exists in the range surrounded by the anomaly contour line (high). The staff can roughly judge the anomaly direction by the density between the anomaly contour lines and the changing trend of the anomaly contour lines. The field distribution composed of at least one anomaly contour line provides the staff with a basis for determining the anomaly direction, thereby facilitating the staff's work.

[0148] A possible implementation of the embodiment of the present application is, in step S1051, determining the abnormal trend according to the abnormal concentration center and each abnormal contour line, including:

[0149] Step S1051a (not shown in the figure): if there is only one abnormal contour line, determine the long axis direction of the abnormal contour line, and use the long axis direction as the abnormal trend.

[0150] The major axis direction is the direction of the straight line segment with the largest distance between two points on the anomaly contour line, and the straight line segment passes through the anomaly concentration center.

[0151] Specifically, when there is only one anomaly contour line in the element anomaly area, with the anomaly concentration center as the center point, straight lines are drawn in all directions until they reach the boundary of the element anomaly area. The anomaly contour line is a closed figure, and the straight line drawn along the anomaly concentration center will be divided by the anomaly contour line. According to the length of each line segment surrounded by the anomaly contour line, the direction corresponding to the longest line segment among all the line segments is taken as the major axis direction, and the straight line drawn along the major axis direction is taken as the anomaly direction.

[0152] Step S1051b (not shown in the figure) If there are multiple abnormal contour lines, determine the lowest abnormal contour line farthest from the abnormal concentration center among the abnormal contour lines; determine the long axis direction of the lowest abnormal contour line; and use the long axis direction as the abnormal trend.

[0153] Specifically, when there are multiple anomaly contour lines, in order to maximize the detection range of element anomaly areas and to improve the coverage of verification, when there are multiple anomaly contour lines, the long axis direction corresponding to the anomaly contour line farthest from the anomaly concentration center is taken as the anomaly trend.

[0154] Among them, the element content in the abnormal concentration center is the highest. The farther the abnormal contour line is from the abnormal concentration center, the lower its element content is. Therefore, the abnormal contour line farthest from the abnormal concentration center is the abnormal contour line with the lowest element content, that is, the lowest abnormal contour line. The long axis direction corresponding to the lowest abnormal contour line is taken as the abnormal trend. The lowest abnormal contour line is the contour line at the outermost periphery of the abnormal concentration center. Points and slots are opened along its long axis direction, which can cover the most likely part of the element abnormal area to the maximum extent, improve the coverage rate of staff verification, and thus reduce the omission rate of staff verification work.

[0155] In a possible implementation of the embodiment of the present application, in step S104, determining at least one horizontal point groove position includes:

[0156] Step Sb1 (not shown in the figure), if there is only one abnormal contour line, a transverse point slot position is set with the abnormal concentration center as the center and the abnormal strike direction, and the interval between two adjacent transverse point slot positions is a preset reference interval.

[0157] Specifically, when there is one anomaly contour line, the interval between the transverse point and slot positions is a preset reference interval, and the positions are set along the anomaly direction according to the reference interval.

[0158] Step Sb2 (not shown in the figure): if there are multiple abnormal contour lines, the interval between the positions of each horizontal point and slot between two adjacent abnormal contour lines is determined according to the distance between two adjacent abnormal contour lines on the abnormal trend and the difference in element content between the adjacent abnormal contour lines; the position of each horizontal point and slot is determined according to the interval between the positions of the horizontal point and slot and the abnormal trend.

[0159] Specifically, according to the distance between adjacent abnormal contour lines on the abnormal trend and the difference in element content corresponding to the two abnormal contour lines, the value of the difference divided by the distance is calculated, that is, the ratio between the difference and the distance is calculated. The ratio represents the rate of change of the element content per unit distance on the abnormal trend. The smaller the rate of change, the sparser the arrangement of the abnormal contour lines at the current position, and the less likely it is to produce mineral (ization) bodies at this position.

[0160] Therefore, in order to reduce the omission rate during verification by staff, when the possibility of the generation of mineral (ization) bodies is greater, the intervals should be denser. Therefore, in a feasible method, the element content change rate is first determined based on the difference between the distance between two adjacent abnormal contour lines and the element content. When the element content change rate exceeds the preset change threshold, the interval between each horizontal point slot position between the two adjacent abnormal contour lines is determined to be the preset first interval; when the element content change rate is less than or equal to the preset change threshold, the interval between each horizontal point slot position between the two adjacent abnormal contour lines is determined to be the preset second interval, and the preset first interval is smaller than the preset second interval.

[0161] The greater the element content change rate, that is, the greater the possibility of the existence of a mineral (formation), the denser the interval between the horizontal point slot positions set between the two adjacent abnormal contour lines, so as to reduce the possibility of omission; the smaller the element content change rate, that is, the smaller the possibility of the existence of a mineral (formation), the sparser the interval between the horizontal point slot positions set between the two adjacent abnormal contour lines. For example: in the element abnormal area, there are abnormal contour lines a1, abnormal contour lines a2, and abnormal contour lines a3 from the inside to the outside, the preset first interval is 2m, and the preset second interval is 4m; the element content change rate between the abnormal contour lines a1 and the abnormal contour lines a2 is 50%, and the preset change threshold is 30%, then the horizontal point slot positions between the abnormal contour lines a1 and the abnormal contour lines a2 are set at an interval of 2m; the element content change rate between the abnormal contour lines a2 and the abnormal contour lines a3 is 10%, then the horizontal point slot positions between the abnormal contour lines a2 and the abnormal contour lines a3 are set at an interval of 4m.

[0162] Since the line segment within the anomaly contour a1 is the area where the anomaly concentration center is located and has the highest rate of change, the distance between the horizontal point slots will be set at the preset minimum interval for the line segment within the anomaly contour a1. For the line segment outside the anomaly contour a3, the horizontal point slot positions are set according to the preset first interval.

[0163] A possible implementation of the embodiment of the present application includes:

[0164] Step Sc1 (not shown in the figure), obtaining the verification results corresponding to each longitudinal point groove in the abnormal vertical direction;

[0165] Step Sc2 (not shown in the figure): if all verification results are no ore results, a new abnormal trend is established with the intersection of the abnormal trend and the abnormal vertical as the center; the new abnormal trend is located between the original abnormal trend and the abnormal vertical.

[0166] Step Sc3 (not shown in the figure), determining a new horizontal point slot position according to the new abnormal trend.

[0167] Specifically, when the staff's verification results in both the abnormal trend and the abnormal vertical direction are no ore results, that is, in the current two directions, the staff has not verified the mineral (formation) body. In order to further find the source of the anomaly, the new abnormal trend is re-determined based on the original abnormal trend and the abnormal vertical. When determining the new abnormal trend, the intersection of the abnormal trend and the abnormal vertical is taken as the center, the intersection is kept unchanged, and the original abnormal trend is adjusted. In a feasible way, the abnormal trend can be deflected by 45°, so that the new abnormal trend is located in the middle of the original abnormal trend and the original abnormal vertical, and the new abnormal vertical is kept perpendicular to the new abnormal trend.

[0168] Afterwards, determine new lateral point and slot positions based on the new abnormal trend, and carry out verification work one by one based on the lateral point and slot positions on the new abnormal trend to reduce the omission rate.

[0169] The above embodiment introduces a method for verifying geochemical anomalies in vegetation-covered areas from the perspective of method flow. The following embodiment introduces a device for verifying geochemical anomalies in vegetation-covered areas from the perspective of a virtual module or a virtual unit.

[0177] Specifically, the area division module 1002 first divides the geochemical anomaly area acquired by the data acquisition module 1001 into multiple element anomaly areas according to the element types and the distribution positions of various elements. The staff will conduct verification work on each element anomaly area respectively. The abnormal trend determination module 1004 determines the abnormal trend representing the geological changes according to the element content and distribution position corresponding to each sampling point in the element anomaly area, so that the staff can open horizontal point slots in sequence according to the abnormal trend for verification. When the verification results of the horizontal point slot positions are all ore-free results representing no mineral (chemical) body, the abnormal vertical determination module 1005 determines the direction perpendicular to the abnormal trend, that is, the abnormal vertical direction, and opens a longitudinal point slot in the abnormal vertical direction. Verification is performed again at the longitudinal point slot position. According to the distribution of elements in the element anomaly area, a more efficient verification direction is provided for the verification work, which improves the efficiency of the staff and reduces the omission rate.

[0183] An execution module is used for determining the abnormal vertical direction by taking the abnormal concentration center as the intersection of the abnormal vertical direction and the abnormal trend if the abnormal concentration center is the intersection of the abnormal vertical direction and the abnormal trend;

[0184] The execution module is also used to determine the horizontal point slot with the largest element content in the horizontal point slot if no, and use the horizontal point slot with the largest element content as the intersection of the abnormal vertical direction and the abnormal trend to determine the abnormal vertical direction.

[0187] According to the distribution positions corresponding to all abnormal elements in each abnormal equal value element group, the abnormal contour lines corresponding to each abnormal equal value element group are determined;

[0188] According to the abnormal concentration center and each abnormal contour line, the abnormal trend corresponding to the element abnormal area is determined.

[0193] Determine the major axis direction of the lowest anomaly contour;

[0194] The long axis direction is taken as the anomaly trend.

[0196] If there is only one anomaly contour line, the horizontal point slot position is set with the center of the anomaly concentration as the center and the direction of the anomaly strike, and the interval between two adjacent horizontal point slot positions is the preset reference interval;

[0197] If there are multiple anomaly contour lines, the interval between each lateral point slot position between two adjacent anomaly contour lines is determined according to the distance between two adjacent anomaly contour lines on the anomaly trend and the difference in element content between the adjacent anomaly contour lines;

[0198] The position of each horizontal point slot is determined based on the intervals between the positions of the horizontal point slots and the abnormal direction.

[0200] The result acquisition module is used to obtain the verification results corresponding to each longitudinal point slot in the abnormal vertical direction;

[0201] The re-determination module is used to establish a new abnormal trend with the intersection of the abnormal trend and the abnormal vertical as the center if all verification results are no mine results. The new abnormal trend is located between the original abnormal trend and the abnormal vertical; according to the new abnormal trend, the new horizontal point and slot position is determined.
