Analyzing the effects of natural ventilation caused by excavating the waste pass on the ventilation network of Anguran mine [PDF]
International Journal of Mining and Geo-Engineering, 2023 One of the operating costs of exploiting underground mines is related to ventilation operations. The development of the underground network during the mine life and new excavations will cause a redesign of the ventilation plan over and over again ...

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.
