FIELD: mining, particularly extinguishment of waste dumps formed on mine surface during mining and coal improvement works performing.
SUBSTANCE: method involves supplying cooling solutions or suspensions to fire site; injecting heat-swelling substances in the solutions/suspensions to increase solution/suspension volumes. Volumes of above substances are determined from mathematical expression.
EFFECT: increased efficiency of waste dump extinguishment and increased environmental safety.
