The main means of dust control besides ventilation is irrigation. Production studies at coal mines have shown that irrigation reduces the dustiness of the air at workplaces by 5-15 times. Application of this effective method of dust suppression at the mining enterprises of the Far North is complicated by severe climatic conditions in underground workings and low temperature of rocks. The air temperature in the majority of coal mine workings in the permafrost zone remains negative throughout the year, which excludes the use of water for dust suppression.
