Remote Sealing System for Extinguishing Coal Mine Fires

• Description:
  This paper describes a feasible remote sealing system that has evolved from the Bureau's sponsored research on the extinguishment of coal mine fires. The complete system includes (1) a sonar probe and close circuit television camera for initial probing of the mine entry to be sealed, (2) a fly ash or fly ash-cement system for constructing the seals, (3) a froth foam topping system for completing each seal, (4) a combustion-type inert gas generator for conveying the fly ash and inerting the sealed area, and (5) acoustical equipment for determining the completion and integrity of a seal. Design requirements are briefly summarized for the currently developed remote sealing system. In addition, field problems are reviewed from the performance of a prototype system that was used in a mine fire situation. [Description provided by NIOSH]
