• Description:
  The Bureau of Mines has conducted a systematic study of the rock dust inerting requirements for various coals, using a 20-L laboratory test chamber. Particle sizes of the coals ranged from very fine pulverized-dusts to coarse (minus 20 mesh) dusts. The data show that, with respect to the rock dust inerting requirement, the particle size of the coals has as much of an effect as the standard volatility. In testing various CaC03 rock dusts against a bituminous coal dust, the finer sized rock dusts were more effective. The laboratory rock dust inerting data also showed reasonable agreement with full-scale mine data. Laboratory data on the effect of added methane gas also showed good agreement with mine data.
