of known methods for eliminating some mine accidents associated with
methane-air mixture explosions and fires to develop effective measures. Methodology. It consists in the analysis of the
experience and results of experiments in the elimination of methane-air
mixture explosions and mine fires. Results. The efficiency of air stream reversal
during extinguishing a mine fire, including multiple reversal, is shown. It has been established that fire extinguishing
operations can be considered completed when there is no carbon monoxide in
concentrations higher than the permissible levels at the site of the fire and
in adjacent workings, the normal ventilation mode in the mine is restored and
the air temperature does not exceed it usual
(background) indicators for these workings. Practical significance. To effectively
extinguish fires, it has been established that they carry out the
opening of an isolated area for reconnaissance, reduce the isolated volume
and other work carried out in accordance with the developed measures,
excluding the penetration of fresh air into the isolated space, the
development of heat and the possibility of new air gas explosion. Keywords: liquidation, mine, accident,
explosions, methane-air mixtures. REFERENCES 1. Pravila bezopasnosti v ugolnyh
