Face Ventilation in Underground Bituminous Coal Mines. Airflow Characteristics of Flexible Spiral-Reinforced Ventilation Tubing
The report describes methods and results of studies to determine friction and shock losses encountered in auxiliary face ventilation systems for underground bituminous coal mines, using flexible, spiral-reinforced ventilation tubing. The results, tabulated in graphic form, simplify fan selection and enable mine operators to design adequate auxiliary ventilation systems. A sample problem shows the use of graphs in calculating characteristics.
