Face ventilation in underground bituminous coal mines
Airflow and methane distribution patterns developed in equipment-free entry 6.5 ft high and 12 ft wide, ventilated by line brattice operated blowing to or exhausting from face, were determined by Bureau of Mines for varying conditions; results of these studies show that blowing line brattice systems of face ventilation are more effective than comparable exhaust systems.
