Fire Diagnostic Simulation for Burning Coal Waste Banks.
Proc 1990 Mining & Reclamation Conf & Exhibition West Virginia Univ Pub Svc 1990 2:521-525
Past research has shown that extinguishing abandoned underground mine fires has not been successful because of the inability to locate fire zones accurately. The U.S. Bureau of Mines has developed a mine fire diagnostic technique that determines gas signatures and pressure flows in the mine atmosphere from a two- dimensional array of boreholes that intersect the strata of an abandoned mine. This technique has worked well in delineating both heated and nonheated subsurface zones at several abandoned mine fire sites. To apply this same technology to fire zones in burning coal waste piles requires a three-dimensional array of boreholes in the pile. Utilizing a scale model of a coal waste pile, the Bureau is currently studying the flow fields that would be induced by a three- dimensional array of boreholes. This report describes some initial results of these physical modeling studies.
