    • Description:
      "During the period from January to May 1982, the U.S. Bureau of Mines carried out a continuous field test of the burnout control process for controlling abandoned mined-land fires. In this process, the rate of burning of an underground mine fire is accelerated through the action of a suction fan, which pulls and collects hot combustion gases from the mine while causing air to flow over the fire. Burnout control thus controls the emission of heat and fumes from the mine fire, and produces sufficient thermal power to run a small electrical generation plant. Previous reports in this five-part series have described the design, construction, and instrumentation of the burnout control system at Calamity Hollow, Allegheny County, Pennsylvania, and the quenching and excavation process by which the fire was cooled and finally extinguished after this particular experimental field test. This report, which completes the full description of the calamity hollow coal mine fire project, summarizes in detail various aspects of the operational phase of the field test. It includes a chronology of events, a discussion of the technical data, and a summary of results . Despite mechanical and operational problems, the field trial at calamity hollow demonstrated that burnout control is a viable method of controlling an abandoned mine fire." - NIOSHTIC-2 NIOSHTIC no. 10007019
