Three coal mine ventilation studies using sulfur hexafluoride tracer gas.
Pittsburgh, PA: U.S. Department of the Interior, Bureau of Mines, RI 8142, 1976 Jan; :1-19
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.
