• Description:
  Two mine fire experiments were conducted in the NIOSH Pittsburgh Research Laboratory's Safety Research Coal Mine that demonstrated that smoke from diesel-fuel fires of 500- and 660-kW heat-release rates in a return airway can develop, without causing a complete airflow reversal, into a roof layer that can migrate upwind, forming a counterflow to the primary airflow in a crosscut. Subsequently, smoke can penetrate into an intake airway and create a hazardous atmosphere in the intake airway upwind from the fire. Visibility conditions less than 13 m were created by the smoke in the intake airway downwind from the crosscut. Modeling of the event with a three-dimensional, time-dependent, computational fluid dynamics (CFD) program correctly represented the smoke movement. [Description provided by NIOSH]
