The assessment and management of aerological risks in coal mine accidents are based on the development of a data analytics system that hosts design values for various parameters and subsystems related to coal mines, as well as the real-time monitoring of operational parameters through various sensors and devices. This study presents the methodology for monitoring aerological risks. It utilizes mining, geological, and geotechnical conditions for seam extraction, along with statistical data concerning elements of coal mine ventilation and gas drainage systems, to assess aerological risks at individual coal mine functionality levels and individual risk factors. Eight coal mines have been ranked according to their aerological risk level. For rank I, the minimum aerological risk is 0.0769, while the maximum is 0.5698. Rank II is associated with category II mines. Aerological risk for this rank is the lowest and ranges from 0,1135 to 0,3873. In the case of rank III, the minimum aerological risk is 0.057, with a maximum of 0.595. This ranking of coal mines by aerological risk level allows to identify potentially unsafe mines in terms of aerology, and enables us to determine aerological risk mitigation measures (technical, technological, and organizational) for each mine to enhance aerological safety.

Оценка и управление аэрологическими рисками аварий в угольных шахтах основываются на создании информационно-аналитической системы данных, включающей в себя проектные значения показателей разных уровней и подсистем угольных шахт, эксплуатационные значения показателей, отслеживаемых системой мониторинга в реальном времени с использованием различных датчиков и устройств. В настоящем исследовании представлена методология мониторинга аэрологических рисков. На основании горно-геологических и горнотехнических условий отработки пластов, статистических данных по элементам вентиляционных и дегазационных систем угольных шахт приведены результаты оценки аэрологических рисков по отдельным уровням функциональной структуры угольных шахт, а также по отдельным факторам риска. По уровням аэрологических рисков выполнено ранжирование восьми угольных шахт. Установлено, что минимальное значение аэрологического риска I ранга составляет 0,0769, максимальное – 0,5698. Наименьшие значения аэрологического риска II ранга (0,1135–0,3873) относятся к шахтам II категории. Минимальное значение аэрологического риска III ранга составляет 0,057, максимальное – 0,595. Ранжирование угольных шахт по уровням аэрологических рисков позволяет выявить шахты с низким уровнем аэрологической безопасности и для каждой шахты определить направления технических, технологических и организационно-технических мероприятий по повышению аэрологической безопасности.
