A method for designing ore storage yards and dumps in gold mines
A technology for dumps and storage yards, applied in computing, image data processing, special data processing applications, etc., can solve the problem of storage yards that cannot accurately reflect the changing trend of storage yards, and cannot intuitively and truly establish a three-dimensional space. Problems such as the dump site model and the difficulty of formulating multi-period dump site plans have achieved the effect of simple and easy to change the design method and the simple and convenient ground surface fitting method

Problems solved by technology
[0005] Therefore, in the above-mentioned traditional method, the concept of building a three-dimensional space through imagination on a two-dimensional map is usually adopted, and the prism is formed by slicing, and the volume of the prism is calculated to replace the volume of the storage yard and the dump , cannot intuitively and realistically establish three-dimensional storage yard and dump site models
[0006] In addition, when calculating the top boundary line of the storage yard, the top boundary of the storage yard is generally obtained roughly in the form of zooming, and the calculated angle between the top boundary and the bottom boundary changes greatly, which cannot accurately reflect the change of the storage yard trend, resulting in inaccurate calculated stockyard volume
[0007] Secondly, using the traditional dump design method, the volume of the currently designed dump is calculated by slicing. For the design of the dump after the dump is formed, the contour must be redrawn by means of measurement. The next dump site can only be designed again, and it is difficult to make a multi-phase dump site plan at one time

[0065] figure 2 Flowchart for computer-aided design of a yard:
[0066] 1. Import the actually measured 3D terrain data of the mining area surface into the system, generally in DXF format, and build a 3D surface model of the entire mining area from the terrain data, which is the spatial surface of the GRID data model;
[0067] 2. On the surface model, select the area to build the storage yard according to the change of the terrain. Given the bottom elevation of the storage yard 7, delineate the boundary range of the storage yard at the given elevation in the three-dimensional space with the top view;
[0068] 3. Generate the bottom surface of the storage yard after the storage yard has been leveled based on the delineated bottom boundary line 1 of the storage yard. The bottom surface is the spatial surface of the TIN data model, and the shearing analysis is carried out by using the vector shear analysis module between the spatial surface and the surface , to establish a fill...

The invention discloses a method for designing an ore stockyard and a dump site in gold mines using the heap leaching method in the dressing and smelting operation. The stockyard boundary is determined, the stockyard is leveled, the filling or excavation of the leveled site is calculated, and the amount of filling or excavation is displayed in a 3D model; the 3D model of the stockyard is created; the 3D model of the dump site is created; Surface stitching; volume calculation of the 3D model of the last storage yard and dump. The use of the present invention can significantly improve the working efficiency and precision of the mine pile and row plan; it can intuitively and conveniently display the three-dimensional space form of the mine pile and dump; the user can conveniently adjust the design result after analyzing it , redesign; the designed dump can be fitted with the surface to form the final 3D model, which facilitates the design of the dump in the later stage and realizes the design of the dump for multiple periods and years.
Description
technical field [0001] The invention belongs to the fields of true three-dimensional computer-aided design and mine informatization and digitization, and specifically relates to a method for designing ore storage yards and dumping dumps in gold mines. Background technique [0002] Since the 1980s, mines at home and abroad have mostly used software for mine design and production management. Mining software such as Supac, Micromine, and Datamine are used abroad. Domestic mines usually use the drawing and calculation technology in AUTOCAD for the auxiliary design of ore heap leaching and waste rock discharge in mine operation, and mainly draw two-dimensional plane diagrams. By calculating the area of each tangent plane on the tangent diagram, Use the method of calculating the volume of the prism to calculate the volume of the stockyard and dump. [0003] For the storage yard, the bottom line of the storage yard is usually delineated on the drawing, and the range is scaled o...
