Treffer: Predictive Mathematical and Computer Model for Determining Harmful Effects of Dust Pollution on the Environment and Workers.

The paper is devoted to mathematical modeling and computer simulation of the process of movement of dust particles in the working area of quarries and adjacent territories in order to protect workers of mining enterprises. The object of the research is a three-dimensional digital model of the relief of a quarry that is currently under development. The subject of the research is simulation the trajectory of dust particles and determining the zones of their maximum permissible concentration, taking into account the prevailing meteorological characteristics of the area. The scientific and practical value of the research results of this article lies in the fact that for the first time the regularities of aerodynamic processes occurring in the working area of quarries and adjacent territories, taking into account the exact shape of the contour of the quarry itself and the corresponding profile of its geological section, were determined by mathematical modeling and computer simulation methods.
