Analysis of Noncoal Mine Atmospheres - Toxic Fumes from Explosives.
NTIS: PB/262-510 Available for Reference At Bureau Libraries :41 pages
Toxic fumes generated during short firing were measured in a phosphate rock mine and a copper mine. Fumes generated during firing of explosives in the Bureau of Mines 1,350-ft3 test chamber were also measured. The release of fumes from water gels, ammonium- nitrate-oil mixtures, and nitroglycerin-based explosives was studied. Direct reading instruments were used to monitor the fume concentrations. The amount of CO produced per unit weight of nitroglycerin explosives (0.41 Ft3/200 grams) was higher than that produced by ammonium-nitrate-oil mixture (0.24 Ft3/200 grams) and water gels (0.16 Ft3/200 grams). The amount of nox produced by nitroglycerin-based explosives was also higher than the amount produced by water gels or ammonium-nitrate-oil mixtures.
