Abstract
Coals and rock dusts used at the U.S. Bureau of Mines experimental mine at Lake Lynn Laboratory, the Polish Experimental Mine Barbara, and German Experimental Mine Tremonia were tested in the Bureau of Mines 20-l explosibility test chamber. The U.S. Pittsburgh seam coal had a volatility of 36 pct, the Polish coal had a volatility of 35 pct, and the German coal had a volatility of 23 pct. Samples of the rock or stone dust used at the experimental mines were used to inert the three coals. The data showed that the pulverized U.S. and Polish coals were similar in size and required similar amounts of rock dust to be inerted. Although the German coal was lower in volatility, it was finer in size than the other two pulverized coals and required somewhat more rock dust to be inerted. These laboratory data comparisons will be useful in analyzing the experimental mine data.
