Abstract:
The paper presents a series of experiments on coal dust samples from coal seams prone to spontaneous combustion. The fractional composition of the samples was estimated. The parameters of thermal decomposition of coal dust have been determined, which give an idea of the fire-hazardous properties of coal. It was found that particles with a size of 50-150 microns predominate in all samples. In the considered sample, it was found that samples with the highest index of chemical activity are characterized by the lowest temperature values at all stages of thermal decomposition, and the amount of mass gain depends on the fractional composition. The results of the study are of scientific and practical interest for the development of a method for controlling endogenous fire hazard by the express method during underground coal mining.
Keywords:
