Theoretical basis for the formation of damaging factors during the coal aerosol explosion

Purpose. Assessing the process of damaging factors formation during coal aerosol explosion in mine workings on basis theoretical research dust deposits order to substantiate promising methods protecting miners from their impact. Methods. An integrated approach is used, which includes a critical analysis literature data occurrence and development explosions workings; into state gaseous medium at characteristic points diagram as result mining operations based laws classical physics chemistry. Findings. The main aspects mechanism powdery state, accumulated surfaces along working perimeter, such negative effect accelerated movement, have been revealed; high temperature formed methane detonative combustion; increased gas pressure. revealed make it possible determine directions for protection caught explosion. settled with normal ventilation conditions, taking account influence seismic waves, has improved. Originality. Analytical dependences, reflecting value energy diagram, determined, dynamics caused by revealed. Practical implications. Possible ways impact reducing severe consequences accidents are proposed.
