Rapid Response Pneumatic Fire Detection for Multilevel Metal Mines: System Design and In-mine Testing.
Pomroy-WH; Griffin-RE; Ackerson-MA
This report describes research by the U.S. Bureau of Mines to design and in-mine-test a rapid response pneumatic fire detection system for multilevel metal mines. The relative merits of pneumatic detection are discussed in the context of typical multilevel mine layouts and environments. The Bureau's prototype system is described, with emphasis on design features that counter commonly experienced and/or perceived operating problems with pneumatic detection systems. Finally, the results of a 3-yr in-mine performance evaluation of the prototype system are discussed.
