摘要：

An experimental investigation of requirements for coal dust inerting was conducted in a 26 l, spherical chamber. A mine-face sample of coal from the Prince mine of the Cape Breton Development Corporation was tested; rock dusts used were limestone, dolomite (two particle sizes) and magnesite. Limestone, dolomite and magnesite (all having approximately the same particle size) were found to be similar in inerting effectiveness, indicating that the decomposition reaction of the endothermic rock dust did not exert an effect over the short time scales during which the volatiles burn during an explosion. Tests with the two sizes of dolomite showed that a decrease in rock dust particle size could significantly lower the amount required to inert.
