Assessment of Dispersing Tracer Gas With Ventilation Air Stream to Detect Mine Fires.
NTIS: PB/84-202696 :69 pages
A remote heat-activated stench gas-tracer gas mine alarm system was developed to reduce the time between fire detection and personnel notification. The stench gas-tracer gas system contains ethyl mercaptan for personnel warning and a fluorocarbon for tracer gas detection by instrumentation. A system was also developed that can be interfaced with multiplex mine phones. In-mine tests were conducted and several systems were presently installed in a hard- rock mine.
