FIELD: mining industry.
SUBSTANCE: method of loading wells, according to which the explosive to be loaded into the well is treated with wet heat carrying agent at a temperature of 50-70°C until an explosive mixture is obtained with a humidity of 1.0-2.5%. Explosives on the base of porous granulated ammonia nitrate and containing liquid and/or solid fuel are used as an explosive.
EFFECT: invention makes it possible to increase the degree of crushing rock, the capacity of transport and loading equipment, to increase the yield of rock mass, to improve reaming of the bench toe, to widen the network of drilling wells and to reduce specific consumption of explosives.
