A Full-Scale Investigation of the Fuel-Load Hazard of Timber Sets in Mines.

摘要

Seventeen mine gallery fire tests were completed during the period October 1, 1976to November 30, 1977,directed toward identifying a hazardous timber-set fuel-loading in a mine passageway that is otherwise free of combustibles. Results of these initial tests show that the capability of a particular fuel loading for propagating a fire is dependent upon the imposed ventilation air velocity and the ignition intensity,although this dependency needs to be better defined. It is also apparent that care must be taken when relating gallery test fire behavior to actual mine fire behavior,because of the restrictive length of the gallery. Present data indicate that some modification to the instrumentation scheme may be advantageous before proceeding with future tests.
