Abstract
The objective of this work was to study the way in which jet fans are used to improve ventilation in metal and nonmetal mines with large cross-sectional areas and to develop guidelines for optimizing this performance. Two different sized jet fans and three separate mines were used in the study. The report gives guidelines on optimal fan location and attitude for ventilating open airways, face areas, and dead headings. The results are only for mines with initially low mean entry air velocities and should not be extrapolated to mines with higher air velocities. The appendix, "using auxiliary 'jet fans' in large underground metal/nonmetal mines: a handbook," is available also as a separate report, OFR 107- 84.
