Description

Technical Field

[0001] The present application relates to the field of mineral exploration technology, and in particular to a method and device, medium, and terminal for determining mineral resource reserves. Background Art

[0002] Determining the reserves of mineral resources (i.e. determining the quantity of industrially useful underground minerals) is an extremely important link in mineral exploration work. It is an important basis for estimating the economic value of mineral deposits, determining the production scale and service life of mines, etc.

[0003] Since the natural form of the ore body is complex and deeply buried underground, and is affected by a variety of geological factors, when determining the reserves of mineral resources, we can only approximately describe or replace the real ore body with regular geometric bodies to determine the volume of the ore body. At present, common methods include arithmetic mean method, geological block method, mining block method and cross-section method. The above methods all determine the reserves of mineral resources on the basis of considering the ore body as an approximate plate-like body.

[0081] The present application provides a method and device, medium, and terminal for determining mineral resource reserves.

[0106] The present application embodiment provides a method for determining mineral resource reserves, such as Figure 1 As shown, the method includes:

[0107] 101. Obtain mineral exploration data of the target ore body.

[0108] Among them, mineral exploration data includes exploration point location distribution data and grade distribution data of each exploration point; exploration point location distribution data, such as Figure 2As shown, the dots represent exploration points; the grade distribution data of the exploration points, for example, the ore body grade is 30% at 10-15 meters, 40% at 15-20 meters, 50% at 20-25 meters, etc. In the embodiment of the present application, the current execution end may be a mineral resource reserve monitoring module of a mining system.

[0109] 102. Based on the exploration point location distribution data, the boundary of the target ore body is delineated to determine the boundary contour of the target ore body. The boundary contour is divided into blocks based on the vertical bisection method to obtain multiple blocks, and the horizontal area of ​​each block is calculated.

[0110] Each block contains an exploration point. In the embodiment of the present application, the boundary contour of the target ore body needs to be Figure 2 All the exploration points in the target ore body are surrounded. Therefore, when delineating the boundary of the target ore body, the line between the exploration points can be extended in the reverse direction for a certain length to obtain the boundary points, and then the boundary points are connected. Furthermore, the boundary contour is divided into multiple blocks based on the vertical bisection method. Since the block division is based on the location of the exploration point, the distribution of mineral resources in each block is relatively consistent with the distribution of mineral resources at the location of the exploration point, which reduces the error caused by directly treating the ore body with different thickness and extremely irregular shape as an approximate plate-like body for volume estimation. Finally, the horizontal area of ​​each block is calculated.

[0111] 103. Determine the mineral resource reserves of the target ore body based on the horizontal area of ​​each block and the grade distribution data of the exploration points contained in the block.

[0112] In the embodiment of the present application, the mineral resource reserves of the target ore body can be calculated by two methods. First, for a single block, the thickness of the ore body of each grade can be determined according to the grade distribution data, and then the ore body thickness can be multiplied by the horizontal area of ​​the block to obtain the volume of the ore body of each grade. Then, the mineral resource reserves of each grade can be calculated according to the volume of the ore body of each grade, and then the mineral resource reserves of all grades can be added together to obtain the mineral resource reserves of the block. Finally, the mineral resource reserves of all blocks can be added together to obtain the mineral resource reserves of the target ore body. Second, similarly, First, for a single block, the thickness of the ore body of each grade is determined according to the grade distribution data, and then the thickness of the ore body of each grade is added to obtain the total ore body thickness of the block, and then the proportion of the thickness of the ore body of each grade in the total ore body thickness is calculated to obtain the proportion of the thickness of the ore body of each grade, and then the proportion of the thickness of each ore body is multiplied by the corresponding grade and weighted summed to obtain the weighted grade of the block, and the weighted grade is multiplied by the total ore body thickness to obtain the mineral resource reserves of the block, and finally the mineral resource reserves of all blocks are added to obtain the mineral resource reserves of the target ore body. Both of the above calculation methods are acceptable, and are not specifically limited in the embodiments of the present application.

[0113] Compared with the prior art, the embodiment of the present application first delineates the boundary contour of the target ore body based on the exploration point location distribution data, and then divides the target ore body with the delineated boundary contour into multiple blocks based on the vertical bisection method, and further calculates the mineral resource reserves of the target ore body according to the horizontal area of ​​each block and the grade distribution data of the exploration point in the block. Since the block division is based on the location of the exploration point, the mineral resource distribution in each block is relatively consistent with the mineral resource distribution at the exploration point location, which reduces the error caused by directly treating the ore body with different thicknesses and extremely irregular shapes as an approximate plate-like body for volume estimation. Moreover, since the mineral resource distribution in each block is consistent with the mineral resource distribution at the exploration point location, the block mineral resource reserves calculated according to the horizontal area of ​​the block and the grade distribution data of the corresponding exploration point are more accurate, thereby making the calculated mineral resource reserves of the target ore body more accurate.

[0114] The present application embodiment provides another method for determining mineral resource reserves, such as Figure 3 As shown, the method includes:

[0115] 201. Connect each adjacent exploration point in the exploration point location distribution data with a straight line to obtain an exploration point network structure diagram.

[0116] The network structure diagram is composed of a plurality of adjacent triangles, and the exploration points located on the boundary line of the network structure diagram are peripheral exploration points. Figure 4 As shown in the figure, the exploration points located on the boundary line of the network structure diagram are peripheral exploration points, and the exploration points located inside the boundary line of the network structure diagram are internal exploration points.

[0117] 202. Extract adjacent triangles of each peripheral exploration point respectively, extend the sides of the adjacent triangles by a preset length in the direction of the boundary line of the network structure diagram respectively, and obtain a plurality of boundary contour points.

[0118] The preset length can be set according to the taste data of the surrounding exploration points. For example, if the taste data of the surrounding exploration points is high, the preset length can be appropriately lengthened, such as two-thirds of the length of the side of the adjacent triangle; if the taste data of the surrounding exploration points is average, the preset length can be shortened, such as one-half of the length of the side of the adjacent triangle. In the embodiment of the present application, the boundary contour points are distributed, such as Figure 5 As shown in the figure, the endpoints of each line segment are boundary contour points.

[0119] 203. Connect each boundary contour point in sequence with straight lines to determine the boundary contour of the target ore body.

[0120] Among them, the boundary contour, such as Figure 6 shown.

[0121] 204. Draw the perpendicular bisectors of each side of each triangle.

[0122] Among them, the perpendicular bisectors intersect at the orthocenter of the triangle.

[0123] 205. Extend the perpendicular bisector in the direction of the boundary line of the boundary contour so that the perpendicular bisector intersects with the boundary line of the boundary contour, thereby obtaining a plurality of intersection points between the perpendicular bisector and the boundary line of the boundary contour.

[0124] 206. Based on the intersection points of the plurality of perpendicular centroids and the plurality of perpendicular bisectors with the boundary line of the boundary contour, perform a segment division operation on the boundary contour to obtain a plurality of segments.

[0125] In the embodiment of the present application, according to the steps 204-206 of the embodiment, Figure 6 The boundary contour in is divided into multiple polygonal blocks, and the block segmentation of the target ore body is as follows: Figure 7 shown.

[0126] 207. Determine the mineral resource reserves of the target ore body according to the horizontal area of ​​each block and the grade distribution data of the exploration points contained in the block.

[0127] In the embodiment of the present application, the mineral resource reserves of the target ore body can be calculated by two methods. First, for a single block, the thickness of the ore body of each grade can be determined according to the grade distribution data, and then the ore body thickness can be multiplied by the horizontal area of ​​the block to obtain the volume of the ore body of each grade. Then, the mineral resource reserves of each grade can be calculated according to the volume of the ore body of each grade, and then the mineral resource reserves of all grades can be added together to obtain the mineral resource reserves of the block. Finally, the mineral resource reserves of all blocks can be added together to obtain the mineral resource reserves of the target ore body. Second, similarly, First, for a single block, determine the ore body thickness of each grade based on the grade distribution data, then add up the ore body thickness of each grade to get the total ore body thickness of the block, then calculate the proportion of the ore body thickness of each grade in the total ore body thickness to get the proportion of ore body thickness of each grade, then multiply the proportion of each ore body thickness with the corresponding grade and take weighted sum to get the weighted grade of the block, multiply the weighted grade with the total ore body thickness to get the mineral resource reserves of the block, and finally add up the mineral resource reserves of all blocks to get the mineral resource reserves of the target ore body.

[0128] Correspondingly, step 207 of the embodiment includes: determining the thickness of the ore body of each grade in the block segment based on the grade distribution data of the exploration points contained in each block segment; multiplying the thickness of each ore body by the horizontal area of ​​the block segment to obtain the volume of the ore body of each grade in the block segment; multiplying the volume of the ore body of each grade by the grade to obtain the mineral resource reserves of each grade in the block segment; adding up the mineral resource reserves of each grade in the block segment to obtain the mineral resource reserves of the block segment; adding up the mineral resource reserves of each block segment to obtain the mineral resource reserves of the target ore body. Or, based on the grade distribution data of the exploration points contained in each block, determine the ore body thickness of each grade in the block; add up the ore body thickness of each grade to obtain the total ore body thickness of the block; calculate the proportion of the ore body thickness of each grade in the total ore body thickness to obtain the proportion of ore body thickness of each grade; perform weighted summation on the product of each ore body thickness proportion and the corresponding grade to obtain the weighted grade of the block; multiply the weighted grade by the total ore body thickness to obtain the mineral resource reserves of the block; add up the mineral resource reserves of each block to obtain the mineral resource reserves of the target ore body.

[0129] In addition, in the embodiment of the present application, the mineral resource reserves of each grade of ore bodies in the target ore body can also be calculated. Specifically, the thickness of the ore body of each grade in the block segment is determined based on the grade distribution data of the exploration points contained in each block segment; the thickness of each ore body is multiplied by the horizontal area of ​​the block segment to obtain the volume of the ore body of each grade in the block segment; the volume of the ore body of the same grade in each block segment is added to obtain the sum of the volume of the ore body of each grade; the sum of the volume of the ore body of each grade is multiplied by the grade to obtain the mineral resource reserves of each grade.

[0130] In an embodiment of the present application, in order to further define and illustrate, Figure 8 As shown, the embodiment method also includes:

[0131] 301. When a new exploration point is monitored, updated location distribution data of the exploration point is obtained.

[0132] The updated exploration point location distribution data includes the location data of the newly added exploration points. In the embodiment of the present application, if production prospecting is carried out during the production process, newly added exploration points will be generated. The updated exploration point location distribution data, such as Fig. 9 As shown in the figure, the dot on the far right is a newly added exploration point.

[0133] 302. In the updated exploration point location distribution data, the newly added exploration point is connected with each adjacent exploration point by straight lines to obtain an updated exploration point network structure diagram.

[0134] In the embodiment of the present application, the updated exploration point network structure diagram is as follows: Fig.10shown.

[0135] 303. Extract adjacent triangles of the newly added exploration points, and extend the sides of the adjacent triangles of the newly added exploration points by a preset length in the direction of the boundary line of the updated network structure diagram to obtain a plurality of newly added boundary contour points.

[0136] The preset length can be the same as the length used in the first calculation. In the embodiment of the present application, a new boundary contour point distribution is added, such as Fig.11 As shown in the figure, the endpoint of the rightmost line segment is the newly added boundary contour point.

[0137] 304. Update the boundary contour of the target ore body based on the multiple newly added boundary contour points to obtain an updated boundary contour.

[0138] In the embodiment of the present application, the newly added boundary contour points are connected with the adjacent original boundary contour points by straight lines to update the boundary contour of the target ore body. The updated boundary contour is as follows: Fig.12 shown.

[0139] 305. Draw the perpendicular bisectors of the sides of the adjacent triangles of the newly added exploration points.

[0140] Among them, the perpendicular bisectors intersect at the orthocenters of the adjacent triangles of the newly added exploration points.

[0141] 306. Extend the perpendicular bisector toward the boundary line of the updated boundary contour so that the perpendicular bisector intersects with the boundary line of the updated boundary contour, thereby obtaining an intersection point of the perpendicular bisector and the boundary line of the updated boundary contour.

[0142] 307. Connect the intersection points of the orthocenter and the perpendicular bisector with the updated boundary contour line with straight lines to obtain a newly added block segment where the newly added exploration point is located.

[0143] In the embodiment of the present application, according to the steps 305-307 of the embodiment, the newly added block segment where the newly added exploration point is located can be obtained, such as Fig.13 As shown in the figure, the polygon where the rightmost circle is located is the newly added block segment.

[0144] 308. Update the mineral resource reserves of the target ore body based on the mineral resource reserves of the newly added block.

[0145] It should be noted that according to Fig.13 It can be seen that after a new exploration point is added, the two blocks adjacent to the new exploration point are re-divided, resulting in overlapping parts between the new block and the two adjacent original blocks. In order to improve the accuracy of mineral resource reserve determination, in an embodiment of the present application, the new block and the updated block of the adjacent block after the new exploration point are used to replace the original block of the adjacent block, so as to avoid the problem of decreased accuracy in mineral resource reserve determination caused by the overlapping parts.

[0146] Correspondingly, step 308 of the embodiment specifically includes: obtaining the original mineral resource reserves of the blocks adjacent to the newly added blocks, and calculating the updated mineral resource reserves of the adjacent blocks after the newly added exploration points; subtracting the original mineral resource reserves of the adjacent blocks from the mineral resource reserves of the target ore body, and adding the updated mineral resource reserves and the mineral resource reserves of the newly added blocks to obtain the updated mineral resource reserves of the target ore body.

[0147] In a specific application scenario, the location of the newly added exploration point can be outside the already defined boundary or within the boundary. The embodiment of the present application does not make specific limitations. The specific method for determining the mineral resource reserves is the same as the method described above and will not be repeated here.

[0148] The present application provides a method for determining mineral resource reserves, firstly obtaining mineral exploration data of a target ore body, wherein the mineral exploration data includes exploration point location distribution data and grade distribution data of each of the exploration points; secondly, performing a boundary delineation operation on the target ore body based on the exploration point location distribution data to determine the boundary contour of the target ore body, performing a block segmentation operation on the boundary contour based on a vertical bisect method to obtain a plurality of blocks, calculating the horizontal area of ​​each of the blocks, wherein each of the blocks contains an exploration point; finally, determining the mineral resource reserves of the target ore body according to the horizontal area of ​​each of the blocks and the grade distribution data of the exploration points contained in the blocks. Compared with the prior art, the embodiment of the present application first delineates the boundary contour of the target ore body based on the exploration point location distribution data, and then divides the target ore body with the delineated boundary contour into multiple blocks based on the vertical bisection method, and further calculates the mineral resource reserves of the target ore body according to the horizontal area of ​​each block and the grade distribution data of the exploration point in the block. Since the block division is based on the location of the exploration point, the mineral resource distribution in each block is relatively consistent with the mineral resource distribution at the exploration point location, which reduces the error caused by directly treating the ore body with different thicknesses and extremely irregular shapes as an approximate plate-like body for volume estimation. Moreover, since the mineral resource distribution in each block is consistent with the mineral resource distribution at the exploration point location, the block mineral resource reserves calculated according to the horizontal area of ​​the block and the grade distribution data of the corresponding exploration point are more accurate, thereby making the calculated mineral resource reserves of the target ore body more accurate.
