As a rule, mines in the Far North, which develop 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 1 m3, and in summer it approaches the sanitary norm ...
