Characteristics of Dust in Ventilation Air from Hard Coal Mine Exhaust Shafts and Its Implications for VAM Utilisation Technologies

Methane contained in ventilation air from hard coal mines (VAM, ventilation air methane) represents a significant environmental and technological challenge due to very large volumetric airflow rates and low methane concentrations. The feasibility of applying VAM utilisation techn...
