FIELD: mining industry. SUBSTANCE: method for rock breaking includes drilling of holes, preparation of hot-flowing explosive by introduction into hot aqueous solution of oxidizer, thickener and sensitizer, placing in holes of means of initiation and explosives, stemming and blasting. Sensitizer is introduced into solution on blasting operation site. Temperature of prepared liquid explosive is reduced before its filling into hole down to value lesser than that adversely affecting service properties of initiation means. EFFECT: higher efficiency.
