• Assessing the Methane Hazard of Gassy Coals in Storage Silos
  1/1/1981 - Reports of Investigations
  The Bureau of Mines investigated coal storage silos to determine how gassy coal must be for methane accumulations in a silo to become hazardous and where such accumulations are likely to occur. Methane concentrations were measured in the open space abov...
• Methane Emissions from Gassy Coals in Storage Silos
  1/1/1978 - Reports of Investigations
  The methane gas emitted from coal samples collected from the conveyor belts dumping into silos was measured. Approximately 50 pct of the total gas desorbed into a sealed can within 1 week was released during the first 24 hours. No simple correlation bet...
