Abstract

The analysis and necessity for studying of burning processes of systems formed by coal dust and methane for the purpose of development the effective activities on the enterprises of coal branch were shown. The results demonstrate the role of nonflammable components in the combustion processes of air suspension in heterogeneous systems. Also the dependence of the critical conditions creation for flame propagation in air suspension of sucrose from the average particle diameter at different temperatures of the ignition source is presented. The necessity of taking into account the experimental and methodological experience of other industries for the study of air suspension sensitivity to the initiating influence of the ignition source is explored. The requirements to the installation and methodology for studying the sensitivity of coal dust air suspension as one of the main factors preventing explosions of heterogeneous systems in the coal industry are formulated.
