Air always flows along the path of least resistance, but this may not be where it is required for use. To direct the air where it is needed, ventilation devices are necessary; the primary means of producing and controlling the airflow for the entire system are mine fans .File Size: 104KB
Jan 01, 2008· The characteristics, including dust loading, particle size, mineral matters of the dust, variations in methane concentration and flow rate, and other compounds , could make a potential VAM mitigation and utilisation technology unfeasible if it cannot cope with the characteristics of mine site ventilation air flows. Therefore, it is important to understand the characteristicsCited by: 113
Air always flows from a point of higher to lower pressure. * Blowing fans create a high pressure point immediately inby the fan. Air travels from this high point through the mine to the surface. * Exhausting fans create a low pressure point immediately inby the fan. Air travels from the surface through the mine to this low pressure point.
Therefore, this paper presents mine site experimental results on the characteristics of mine ventilation air flows, including methane concentration and its variations, dust loadings, particle size, mineral matter of the dust, and other compounds in the ventilation air flows. The paper also discusses possible correlations between ventilation air characteristics and undergroundCited by: 113
