FIELD: mining.
SUBSTANCE: method involves supply of frozen fluid obtained by mixing with liquid gas to the worked-out space. In addition, distribution of coal dust supplied to the worked-out space is determined as to particle fractions. Distribution of the obtained frozen fluid particles as to fractions is equal to distribution of coal dust as to particle fractions.
EFFECT: improving the prevention efficiency of coal self-ignition in mines.
