Inżynieria Mineralna, 2022 In underground coal mining, the ventilation task plays an important role because it ensures enough fresh air for workers and decrease negative effects of deleterious gases released from coal seam as well as blasting explosions. Furthermore, when coal mines go deeper, the ventilation task is more and more important.
