Snow sampling sites of the snow cover were located in the area of the road along which coal is transported, and at a distance of 0,5 km from the village of Arshanovo in accordance with the wind rose. Particle size analysis was performed using a LaskaTD device. It was found that in the samples under study, the main proportion of suspended particles, regardless of the point of study, had sizes from 5 to 20 microns, which numerically amounted from 63.8 to 81,3 % of the total weight of suspended substances. The site located in the western direction at a distance of 0,5 km from the Arshanovo had such low values of suspended solids that it was not possible to determine them using the Laska-TD device. The average particle size, depending on the point of study, had the following values (μm): № 1 - 11,2 ± 0,4; № 2 - 11 ± 1,6; № 3 - 9,3 ± 0,2; № 4 - 7,3 ± 0,9; № 5 - 13,5 ± 0,3; № 6 - 11,5 ± 0,2; № 8 - 11,6 ± 0,3. The obtained results of the study allow to conclude that there is a large amount of fine dust in the snow cover, which can accumulate in the environment and negatively affect its biological component, including humans.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Проведен анализ размера частиц взвешенных веществ в образцах снега с различных участков вблизи угледобывающего предприятия ООО «Разрез Аршановский» Республики Хакасия. Точки отбора проб снежного покрова располагались в районе автодороги, по которой транспортируется уголь, и на расстоянии 0,5 км от села Аршаново в соответствии с розой ветров. Анализ размера частиц проводили с помощью прибора «Ласка-ТД». Было установлено, что в исследуемых образцах основная доля взвешенных частиц, независимо от точки исследования, имела размеры от 5 до 20 мкм, что составило от 63,8 до 81,3 % от общей массы взвешенных веществ. Участок, расположенный в западном направлении на расстоянии 0,5 км от населенного пункта, имел настолько низкие значения взвешенных веществ, что определить их с помощью указанного прибора не удалось. Средний размер частиц в зависимости от пункта исследования имел следующие значения (мкм): № 1 - 11,2 ± 0,4; № 2 - 11 ± 1,6; № 3 - 9,3 ± 0,2; № 4 - 7,3 ± 0,9; № 5 - 13,5 ± 0,3; № 6 - 11,5 ± 0,2; № 8 - 11,6 ± 0,3. Полученные результаты исследования позволяют сделать заключение о наличии в снежном покрове большого количества мелкоразмерной пыли, способной накапливаться в окружающей среде и негативно влиять на ее биологическую составляющую, в том числе на человека.</p></trans-abstract><kwd-group xml:lang="en"><kwd>particle size</kwd><kwd>coal mining</kwd><kwd>snow cover</kwd><kwd>Khakassia</kwd><kwd>wind rose</kwd><kwd>coal transportation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>размер частиц</kwd><kwd>угледобыча</kwd><kwd>снежный покров</kwd><kwd>Хакасия</kwd><kwd>роза ветров</kwd><kwd>транспортировка угля</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Bespalova EV, Prozhorina TI, Kurolap SA.
