Within the real conditions of blasting operations the content of explosion products is diverse and differs significantly from
the ideal conditions. Detonation products are chemically more active than aerial oxygen, and they can work with the rock,
coal in particular, which is in active condition. At that, coal combustion possibility rises. The presence of the products of
partial oxidation of combustible additives and trinitrotoluene, which also possess higher chemical activity, also leads to the
similar result. Investigation and observation results in various periods of coal deposits development in Mongolia show that
fires more frequently develop in blocks of coal bench in the rock mass, which has been mined with drilling and blasting
operations. Under rock loosening with a blast, the time of incubation period of coal masses to combustion is shorter as
compared to mining without using drilling and blasting operations. The transfer to the use of granulated coarsely dispersed
explosives at the opencast coal mines of Mongolia has led to the development of unbalanced according to the oxygen
balance system and the emission of a great deal of nitrogen oxides at the time of the explosion. The wide use of mixtures
of ANFO type in the period of 2005 to 2015 has led to massive cases of spontaneous coal combustion and technogenic
fires, which therefore has led to a higher risk of coal deposits exploitation. Investigations fulfilled by the authors allowed
creating for Mongolia conditions special technology of producing and using ammonium nitrate explosives, which possess
balanced composition and evolve minimum quantity of poisonous products during the explosion, which cause accelerated
spontaneous coal combustion. The use of the developed technology of ANFO mixtures production almost eliminates
spontaneous coal combustion after the explosion.

Key words: coal; ammonium nitrate; explosives; combustion; endogenous fire; detonation.
