Description

Technical Field

[0001] This invention relates to the field of geological modeling technology, and in particular to a method for calculating material reserves based on a three-dimensional model and a readable storage medium. Background Technology

[0002] Currently, traditional methods for material yard surveying and design, such as geological mapping and excavation drawing, reserve calculation, excavation design, and stability analysis, still rely on conventional two-dimensional techniques, which can only meet the most basic engineering needs. For material yards with complex terrain and geological conditions (such as irregular, structurally complex, or soluble rock material yards), the traditional two-dimensional working mode lacks an intuitive three-dimensional impression, making it difficult to clearly and vividly express the spatial distribution of geological bodies, and also posing a significant challenge to excavation design. Under the traditional two-dimensional design mode, quantity calculation often uses methods such as average thickness method, parallel section method, and triangulation method, and is limited by the mining area and terrain influence, resulting in low accuracy of quantity calculation, and sometimes even large errors. Summary of the Invention

[0003] To address the shortcomings of existing methods, this invention provides a method for calculating material yard reserves based on a three-dimensional model and a readable storage medium. This method improves the spatial understanding of geological bodies in material yards and the accuracy of material yard reserve calculations, enabling three-dimensional parametric mining design of material yards and improving the efficiency of drawing production during the material yard exploration, design, and construction phases.

[0004] The specific technical solution of the present invention is as follows: a method for calculating the reserves of a material yard based on a three-dimensional model, comprising: importing basic geological data into the system; extracting feature information from the imported data to generate a geological interface; generating a geological body based on the geological interface and dividing the geological body into different geological units; creating an excavation face based on excavation indicators; using the excavation face to trim the geological body; and using the software system's calculation module to calculate the volume of the trimmed geological body units.

[0005] Specifically, the following steps are included:

[0006] S1. Import basic geological data into the database system of Geostation software;

[0007] S2. In the Geostation software drawing system, select point elements or line elements of each stratum interface, and fit the spatial location of each stratum interface by Kriging or weighted average method, including topographic surface, weathering surface of different degrees, stratum interface, material yard reservoir interface, model bottom surface, and groundwater level.

[0008] S3. Generate geological bodies and divide them into different geological units. Generate geological bodies related to the mining of the material yard layer by layer from the ground surface downwards, including the material yard stripping layer, multiple useful layers, and useless interlayers. At the same time, the material yard is divided into two parts above and below water by the groundwater level.

[0009] S4. Determine the material yard mining indicators based on geological conditions and usage requirements, including the material yard excavation range, material yard excavation bottom elevation, design slope ratio of the above-water and underwater slopes, single-layer excavation height, and ramp width. Create the excavation face based on the excavation design indicators.

[0010] S5. In Geostation software, Boolean operations are performed between the excavation face and the geological body to trim the geological body;

[0011] S6. Calculate the volume of the stripping layer, the useless layer, and the useful layer reserves using the volume calculation module built into the 3D software system.

[0012] 3. The method for calculating material yard reserves based on a three-dimensional model according to claim 2, wherein the basic geological data in S1 includes topographic data, geological mapping data, borehole data, test pit data, adit data, hydrological data, and the geological boundary points and geological boundaries contained in these data.

[0013] Furthermore, the method for S4 is as follows:

[0014] S41. Determine the excavation depth or bottom elevation of the material yard;

[0015] S42. Create the excavation face from bottom to top according to the slope ratio of the excavation side, the maximum excavation height of a single layer, and the width of the ramp;

[0016] S43. Keeping the elevation constant, translate and rotate multiple excavation faces horizontally to the edge of the excavation area line;

[0017] S44. Multiple excavation faces can be cut and merged using splicing tools.

[0018] A computer-readable storage medium includes instructions that, when executed on a computer, cause the computer to perform the above-described method for calculating the storage capacity of a material yard based on a three-dimensional model.

[0019] The beneficial effects of this invention are: it improves the spatial understanding of the geological body of the material yard; it enables three-dimensional parametric mining design of the material yard, improving the efficiency of material yard design; the excavation face can be translated and rotated according to the mining range and terrain undulations, maximizing the utilization of the material yard within the mining area; and the use of a three-dimensional model for volume calculation is equivalent to infinitely refining the calculation cross-section in traditional methods, improving the accuracy of material yard reserve calculation.

[0026] The technical solution of the present invention will now be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0027] like Figure 1 As shown, the material yard reserve calculation method based on a three-dimensional model of the present invention imports basic geological data into the system; extracts feature information from the imported data to generate a geological interface; generates a geological body based on the geological interface and divides the geological body into different geological units; creates an excavation face based on excavation indicators; uses the excavation face to trim the geological body; and uses the software system's calculation module to calculate the volume of the trimmed geological body units.

[0028] The specific implementation process is as follows:

[0029] S1: Import basic geological data (boundary points, stratigraphic boundaries, water levels, etc. of surface and subsurface geological stratification from boreholes, adits, and geological mapping) into the Geostation software's database system. See [link to Geostation software]. Figure 2 ;

[0030] S2: In the Geostation software drawing system, select point or line elements for each stratigraphic interface, and fit the spatial location of each stratigraphic interface using Kriging or weighted average methods. This includes topographic surfaces, weathering surfaces of different degrees, stratigraphic interfaces, reservoir interfaces (useful layers, stripped layers, useless interlayers, etc.), model bottom surface, groundwater level, etc. (See...) Figure 3 Topographic surfaces and interfaces in the middle;

[0031] S3: Generate geological bodies and divide them into different geological units. Generate geological bodies related to the mining of the material yard layer by layer from the ground surface down, including the material yard stripping layer, multiple useful layers, useless interlayers, etc. At the same time, the material yard is divided into two parts above water and underwater by the groundwater level.

[0032] S4: Determine the quarry excavation parameters based on geological conditions and usage requirements, including the quarry excavation area, quarry excavation bottom elevation, design slope ratios for above-water and underwater slopes, single-layer excavation height, and walkway width. Create the excavation face based on the excavation design parameters. See [link / reference]. Figure 4 ;

[0033] S5: In Geostation software, Boolean operations are performed between the excavation face and the geological body to trim the geological body. See [link / description]. Figure 5 ;

[0034] S6: Calculate the volume of the stripping layer, useless layer, and useful layer reserves in the material yard using the volume calculation module built into the 3D software system. See [link / reference]. Figure 6 .

[0035] Furthermore, the geological data described in process S1 includes:

[0036] Topographic data, geological mapping data, borehole data, pit data, adit data, hydrological data, and the geological boundary points and boundaries contained in these data.

[0037] Furthermore, the principle of process S2 is as follows:

[0038] Select data with the same geological attributes, such as geological boundary points revealed in boreholes or adits, geological boundaries revealed by geological mapping, and geological boundaries explored by geophysical tests, and use the drawing module of Geostation software to extract the nodes and fit them into a surface.

[0039] Furthermore, the method for process S4 is as follows:

[0040] S4.1: Determine the excavation depth or bottom elevation of the material yard;

[0041] S4.2: Create the excavation face from bottom to top according to the slope ratio of the excavation side, the maximum excavation height of a single layer, the width of the access road, etc.

[0042] S4.3: Keeping the elevation constant, translate and rotate multiple excavation faces horizontally to the edge of the excavation area line;

[0043] S4.4: Use splicing tools to cut and merge multiple excavation faces.

[0044] Example:

[0045] The M material yard of a certain project is located in a high mountain area with significant topographic relief, making the traditional average thickness method unsuitable. Furthermore, the cross-sectional spacing of methods such as the parallel section method and the triangular method is generally large, resulting in poor accuracy in calculating excavation reserves. Adopting a refined reserve calculation method for material yards based on a three-dimensional model can significantly improve the accuracy of material yard calculations. The following is a detailed description of the invention using the refined reserve calculation method based on a three-dimensional model for the M material yard of a certain project. The steps are as follows:

[0046] S1: Import basic geological data (contour lines, boundary points between useful layers and stripped layers in boreholes and shafts, etc.) into the Geostation software's database system. See the borehole and shaft data section for details. Figure 2 ;

[0047] S2: In the Geostation software drawing system, select point or line elements for each stratigraphic interface, and fit the spatial location of each stratigraphic interface using Kriging or weighted average methods. This includes topographic surfaces, the interface between the useful layer and the stripping layer in the material yard, the bottom surface of the model, and the groundwater level, etc. (See...) Figure 3 Topographic surfaces and interfaces in the middle;

[0048] S3: Stretching the stratigraphic interface downwards from the ground, generating geological bodies related to the mining site layer by layer, including the stripping layer and the useful layer, see... Figure 3 ;

[0049] S4: Based on preliminary geological data, the excavation slope ratio for material yard M is determined to be 1:0.375, with a single-layer excavation height of 12m and walkway widths of 6m, 3m, and 3m respectively. The excavation boundary line for the material yard has been determined, with an excavation bottom elevation of 875m. In Geostation software, multiple excavation faces are created from bottom to top according to the excavation slope ratio, maximum single-layer excavation height, and walkway width, keeping the elevation constant. The excavation faces are then horizontally translated and rotated to the edge of the excavation boundary line. The splicing tool is used to cut and merge multiple excavation faces. See [link to documentation]. Figure 4 ;

[0050] S5: In GeoStation software, Boolean operations are performed between the excavation face and the geological body to trim the geological body. A schematic diagram of the trimmed model is shown below. Figure 5 ;

[0051] S6: Calculate the volume of the stripping layer and the useful layer reserves using the volume calculation module built into the 3D software system. See [link / reference]. Figure 6 .

[0052] Three-dimensional models, as an important carrier of three-dimensional geological information visualization, play a supporting role in geological spatial decision-making for three-dimensional collaborative design. Using three-dimensional geological models, the spatial distribution of geological bodies in a material yard and their impact on engineering projects can be clearly and vividly expressed, greatly facilitating the rapid interpretation of geological conditions by engineering geology and geotechnical design professionals, and improving the quality and progress of engineering design.
