Abstract Organic aerosol is formed in coal mines due to heat release and evaporation of organics from coal during the longwall operation. This frictional heating occurs when a metallic cutting bit strikes a rock. Thus formed organic aerosol can contr

It is shown that during mechanical action on coal, along with the emission of gaseous combustible compounds, high-molecular hydrocarbons are released, which, in turn, leads to the formation of an organic aerosol. The lower limit of ignition of a meth

Two approaches to describing an expanding spherical flame are compared. Processing of a large amount of experimental data shows that the approach using as a small parameter a parameter proportional to the strain rate gives a lower accuracy approximat

Combustion of vapors of a flammable liquid whose temperature is below the flash point is under study. In this case, the flame propagates along the surface of the liquid due to being heated by combustion products. The velocities of an oxidizer moving

An approach to studying the influence of the electric field on the flame with separate consideration of the effects of curving and extending of the plane flame is proposed. The degree of deformation can be used as a factor determining the action effi

Flame propagation in a closed vessel containing a stoichiometric propane–air mixture and partially filled with a porous medium has been experimentally studied. It has been shown that the flammability limit in the porous medium is determined by the

The upper flammability limit of ethane–air and ethane–oxygen mixtures was determined experimentally for various initial temperatures and pressures. In the experiments, the upper flammability limit increased with increasing initial temperature and

The mechanism of aerosol formation in coal mines during the operation of a longwall shearer was studied using a diffusion battery, optical counter, and by means of Transmission Electron Microscopy (TEM). The aerosol number concentration was measured
