[0002] The geological block method is a commonly used approach for calculating mineral resource reserves. It divides geological maps into blocks based on exploration data and calculates the reserves of each block. However, the traditional geological block method is a cumbersome process that relies on manual judgment and operation, which is not only time-consuming and labor-intensive but also prone to human error. Therefore, it is particularly important to develop a method that can automatically, accurately, and quickly divide geological blocks. Summary of the Invention

[0008] Furthermore, the automatic segmentation according to the determined base points specifically includes: automatically segmenting the area between each two adjacent exploration lines in sequence according to a preset order.

[0009] Furthermore, the area between two adjacent exploration lines is automatically divided into blocks, specifically including: starting from the base points on the two adjacent exploration lines, dividing the blocks in two directions parallel to the exploration lines, each divided block is a quadrilateral or triangle, and the vertices of the quadrilateral or triangle blocks are all exploration project projection points on the two adjacent exploration lines.

The first exploration project projection point found on the first exploration line along the first direction and the first exploration project projection point found on the second exploration line along the first direction are used as new base points, and step S1 is continued.

[0014] S12.

[0015] Furthermore, the automatic geological block division method of the present invention also includes the following steps: if no new exploration engineering projection point is found on the first exploration line and the second exploration line along the first direction, the block division process along the first direction of the area between the two adjacent exploration lines is terminated.

[0035] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0037] In each accompanying drawing, identical element adopts similar reference numeral to represent.For the sake of clarity, each part in the accompanying drawings is not all drawn to scale.In addition, some well-known parts may not be shown in the drawings.

[0038] Many specific details of the present disclosure are described below to provide a clearer understanding of the present disclosure. However, as will be appreciated by those skilled in the art, the present disclosure may be implemented without following these specific details.

[0039] Figure 1 This is a flow chart of a method for automatically dividing geological blocks provided by an embodiment of the present disclosure. Figure 1 As shown, the present invention provides a method for automatically dividing geological blocks, comprising the following steps:

[0040] Obtain a geological map, where there are several exploration lines, and each exploration line has at least one exploration project projection point;

[0041] Determine the two closest exploration project projection points on each adjacent exploration line as base points;

[0042] Automatically divide blocks into segments based on the determined base points.

[0043] Furthermore, a number of exploration lines are distributed in parallel and at intervals.

[0044] The main elements in a geological map are the exploration lines and the associated prospecting engineering projection points.

[0045] Geology Figure 1 Generally, it is a longitudinal projection cross-section (i.e., vertical longitudinal projection) or a horizontal projection. The geological map of this embodiment is a longitudinal projection cross-section or a horizontal projection based on a prospecting project, and the elements on the map include exploration lines and exploration project projection points.

[0046] Assume that in a plane drawing, the right direction is the positive direction of the x-axis, the upward direction is the positive direction of the y-axis, and a certain point is the origin (0,0). Then the point can be represented by the (x, y) coordinates, and the line can be represented by a point set.

[0047] Exploration line refers to a set of parallel straight lines formed on the surface of the earth, which are arranged in a set of vertical exploration sections that are basically perpendicular to the strike of the ore body. Figure 2 The exploration lines Zhongxi 0, West 1, West 2, etc. are a group of parallel straight lines.

[0048] The exploration project projection points are a series of points that are known to be associated with the exploration line, such as Figure 2 The exploration engineering projection points associated with the Central and West 2 exploration lines are ZK201 and ZK202.

[0049] The present invention also sorts the lines from left to right and numbers them in sequence according to the x size of the points that make up the exploration line; and sorts the points associated with the line from top to bottom according to the y size. Figure 3 Point 4 of the second line is referred to as point 24.

[0050] In some embodiments, determining the two exploration project projection points that are closest to each other on each adjacent exploration line specifically includes: establishing a plane rectangular coordinate system on the geological map, obtaining the coordinates of each exploration project projection point, and calculating the distance between any two exploration project projection points on each adjacent exploration line based on the coordinates of each exploration project projection point to obtain the two exploration project projection points that are closest to each other on each adjacent exploration line.

[0051] If the geological map is a plane map, a rectangular coordinate system is established on the plane map. If the geological map is a vertical longitudinal projection map, that is, a cross-section map, it is only necessary to calculate the spatial position according to the relative coordinates within one coordinate system.

[0052] Of course, the present invention is not limited to the above embodiment. The present invention can also use other methods to calculate the distance between any two exploration project projection points on two adjacent exploration lines.

[0053] Furthermore, the automatic segmentation of blocks according to the determined base points specifically includes: automatically segmenting the area between each two adjacent exploration lines in sequence according to a preset order;

[0054] Automatically divide the area between two adjacent exploration lines into blocks, specifically including: dividing the blocks along two directions parallel to the exploration lines starting from the base points on the two adjacent exploration lines, and each divided block is a quadrilateral or triangle, and the vertices of the quadrilateral or triangle block are all the exploration project projection points on the two adjacent exploration lines.

[0055] The two directions parallel to the survey line are two directions parallel to the survey line and diametrically opposite to each other.

[0056] Starting from base points on two adjacent exploration lines, dividing the blocks along two directions parallel to the exploration lines includes steps A and B. Step A involves dividing the blocks along one direction parallel to the exploration lines, starting from base points on the two adjacent exploration lines; step B involves dividing the blocks along another direction parallel to the exploration lines, starting from base points on the two adjacent exploration lines. Steps A and B can be performed sequentially or simultaneously. There is no specific order for steps A and B; step A can precede step B, or step B can precede step A.

[0057] Furthermore, starting from base points on two adjacent exploration lines, dividing the blocks along any direction parallel to the exploration lines, i.e., a first direction, specifically includes:

[0058] S1. Starting from a base point on a first of two adjacent exploration lines, searching for a new exploration project projection point on the first exploration line along a first direction; starting from a base point on a second of the two adjacent exploration lines, searching for a new exploration project projection point on the second exploration line along the first direction;

[0059] S11. If new exploration project projection points are found on both the first exploration line and the second exploration line along the first direction, four points including the first exploration project projection point found on the first exploration line along the first direction, the first exploration project projection point found on the second exploration line along the first direction, and the two base points are connected to form a quadrilateral to define a segment. The first exploration project projection point found on the first exploration line along the first direction and the first exploration project projection point found on the second exploration line along the first direction are used as new base points, and step S1 is continued.

[0060] S12. If a new exploration project projection point is found only on one of the first exploration line and the second exploration line along the first direction, three points including the first exploration project projection point found on the first exploration line along the first direction or the first exploration project projection point found on the second exploration line along the first direction and the two base points are connected into a triangle and circled as a block segment. The block segment division process along the first direction for the area between the two adjacent exploration lines is completed.

[0061] The present invention uses the exploration line as the control line. The engineering survey conditions on the exploration line are valid for the nearby areas. Similarly, the line connecting the points closest to adjacent exploration lines is also the valid line for judging the area, and then the area is divided in turn.

[0062] Furthermore, the automatic geological block division method of the present invention also includes the following steps: if no new exploration engineering projection point is found on the first exploration line and the second exploration line along the first direction, the block division process along the first direction of the area between the two adjacent exploration lines is terminated.

[0063] Furthermore, after successively calculating the two nearest exploration project projection points of the two adjacent exploration lines, the two nearest exploration project projection points of the two adjacent exploration lines are connected as the connection baseline, as shown in FIG. Figure 4 Points 24 and 33 are the closest points between Line 2 and Line 3, and their connection is confirmed. The survey engineering projection point at one end of the connected baseline is located on the first of the two adjacent survey lines, while the survey engineering projection point at the other end of the connected baseline is located on the second of the two adjacent survey lines. The present invention can start with connecting the baselines and then divide the blocks from above or from below.

[0064] See also Figure 5 The present invention describes the automatic segmentation steps in detail based on the segmentation between the second line and the third line, which specifically includes:

[0065] Divide the blocks upwards:

[0066] 1) Take the connection of the two closest points between the two lines, 24 and 33, as the baseline, and calculate upward to get 23 and 32. Then, 24, 33, 23, and 32 are connected to form a quadrilateral, which is circled as segment V1;

[0067] 2) Then, starting with the line connecting point 23 and point 32, calculate upward to get point 22 and point 31. Then, point 23, point 32, point 22, and point 31 are connected to form a quadrilateral, which is circled as segment V2.

[0068] 3) Continue in this way until only three points are left. Connect them to form a triangle, circle segment V3, and circle upwards to end.

[0069] The downward division of blocks is similar to the upward division, and the V4 block is circled.

[0070] According to the above method, the points between other adjacent exploration lines (straight lines) are divided into blocks, and the following are obtained: Figure 6 As shown, the automatic segmentation is completed. Figure 7 A colored geological map after block connection provided in an embodiment of the present disclosure.

[0071] The present invention also performs result verification and adjustment: the automatically divided blocks are compared with the actual exploration data to ensure the accuracy and reliability of the results. If necessary, the block division is manually adjusted based on the verification results.
