Mining Publication: Three Coal Mine Ventilation Studies Using Sulfur Hexafluoride Tracer Gas
Original creation date: January 1976
This report describes three coal mine ventilation studies by the Bureau of Mines in which sulfur hexafluoride (sf6) was used as a tracer gas. One of these studies was conducted to determine air movement and leakage in a sealed area. Another was run to determine the ventilation efficiency of a bleeder system. Finally, a study was made of air leakage across permanent stoppings of parallel intake airways. These studies proved sulfur hexafluoride to be a useful addition to the equipment commonly used in coal mine ventilation analysis.
