Abstract
The relationship of the fractional composition is revealed and its influence on the explosiveness of the air in coal mines is revealed. The aim of the work is to determine the fractional composition of the studied samples of coal grades “L” (long-flame), “F” (fat) and “A” (anthracite) and its effect on the physical and explosive properties. It has been established that coal dust has a fractional composition containing more than 55% of fractions less than 94 microns and during natural grinding (without discharge of static electricity) in fine fractions (less than 94 microns) there are large conglomerates of particles that disintegrate when exposed to air currents similar to the speed of air movement in mountainous areas. workings. Based on the results obtained, further stages of work on the study of the explosive properties of coal dust are determined. The data on the granulometric and optical types of analysis are presented.
