Features of ventilation of coal mines in the Far North (on the example of mines of the Yakut ASSR)
Authors:
Abstract
Most of the mines we surveyed in the north-eastern part of the country (Norilsk, the Yakut ASSR and other areas) develop mountainous coal deposits lying in the permafrost zone using adit development. As a rule, the mines operate without pre-heating of air during the cold season. Therefore, in the area of extraction panels, with the exception of individual cases, the temperature of the mine atmosphere remains negative throughout the year (minus 2 to minus 4 °C) ...
