Numerical Investigation of Characteristics of Mine Ventilation Using One or Two Ducts in Underground Mining Faces,explained in view of comparisons between the use of one duct (blowing) and two ducts (blowing and exhaust). The airflow around ventilation ducts and mining faces contains complicated vortices, which capture the air, thereby increasing its age and level of dust contamination.
