Abstract
The fire resistance of several mine conveyor belts is evaluated using a new belt-flammability apparatus developed by the U.S. Bureau of Mines. The test, experimental details, and a calculated flammability index (fi) are described. The fi values are useful for ranking the fire resistance of mine conveyor belts. Values are determined using parameters readily measured with thermocouples, high-temperature flow probes, and a methane-oxygen torch, all of which are components of the Bureau's new test apparatus. The fi varies directly with the flame-spread rate and the rate of heat release during burning and varies inversely with the critical (minimum) ignitor energy output. The fire-resistance ranking of nine different belt types using this moderately scaled apparatus is compared with available full-scale data on belt fires. This comparison shows that the ranking based on the fi is consistent with the full-scale data.
