This paper describes an investigation into the effectiveness of gob ventilation and/or sealing practices using sulfur hexafluoride (sf6) tracer gas. Practices at three coal mines were examined, each having different problems associated with mined-out areas. The purpose of these ventilation studies was to better understand whether current techniques employed for ventilation or sealing are successful at minimizing the potential for gob fires and explosions. Employment of the sf6 tracer gas technique resulted in answers to questions raised by the mine operators concerning the effectiveness of their gob ventilation or sealing practices in preventing mine fires.
