As a rule, mines in the Far North, which mine coal seams in permafrost conditions, are characterized by seasonal fluctuations in the dust content of the mine atmosphere. In January–February, the content of dust in the air during excavation, loading and transportation of coal reaches the maximum value – hundreds and thousands of milligrams per m³, and in summer it approaches the sanitary norm. ...
