FIELD: mining industry, applicable at a blast destruction of rocks, mainly by deep-hole charges in open pits.
SUBSTANCE: the device includes an elastic vessel with an inertial body of sealed and contains at least two cells filled with chemical blowing reagents, the cells are separated between each other and the vessel by a destructible partition, or by a valve fixture, or by a device for controllable motion of the reagents and products of chemical reaction between the reagents.
EFFECT: simplified installation of the device in the deep-hole, expanded potentialities of its use and enhanced extent of its use.
