Assessment of dust accumulation from a man-made enrichment tailings storage facility in the city

The results of the assessment of dust deposited on the territory of Apatity are based on data obtained during previously performed numerical experiments to predict atmospheric pollution with fine dust (taking into account the deposition rate) from a man-made enrichment tailings storage facility. The models are developed in the COMSOL program for the ANOF-2 – Apatity tailings storage area. In the course of the study, an algorithm for calculating deposited dust on a horizontal surface has been implemented and a description of modern approaches to assessing secondary dust generation on urban highways has been presented. The interval and total dust masses accumulated during 1 hour on the territory of Apatity are calculated taking into account variations in the dusting area of 2–10 ha (with a random selection of dusty areas on the surface of the tailings dump) and wind speeds of 5–23 m/s. For an analytical description of the average total mass of dust accumulated in 1 hour under the conditions of the indicated ranges of model parameters, a power function of wind speed and a linear dependence on the dusting area are valid. The surface density of РM10 dust accumulated on the motor roads of the town of Apatity for 1 hour during dusting at the enrichment tailings storage facility has been estimated under conditions of variation in wind speed and dusting area. The above estimates of the hourly accumulation of dust on the roads of Apatity are necessary for environmental monitoring and the development of measures to reduce the impact of dust on public health.
