Abstract

The solution of various tasks (determination of production volumes, construction of tunnel sections, accounting for extracted volumes, optimization of quarries, etc.) in mining industries requires the use of resources of geoinformation systems and specialized software complexes. Increasing the accuracy of model products requires an increase in the amount of data. In this case, as a rule, improving the algorithms of software systems allows to increase the speed and/or accuracy of calculations. The work aimed to develop and test an approach to increasing the speed and accuracy of calculating the volume of three-dimensional objects in the mining industry, also by modifying software algorithms. As a result, new algorithms have been developed and programmatically implemented, which suggest a different approach of placing a point cloud in the center of the world coordinate system and constructing a polygon base as a plane with a single horizontal coordinate. The study revealed limitations of existing approaches and software, such as constructing an excessive number of projection edges on the polygon base and using quadratic complexity algorithms. Testing in real production conditions has confirmed the correctness and sufficient accuracy of the results. Testing on geometric primitives showed a reduction in time for measuring the volume of 3D objects by up to 10%.

Keywords: sustainable development, mining, coal warehouses, computational algorithms, digital technologies.
