FIELD: chemistry.

SUBSTANCE: invention refers to industrial non-safety explosives, namely grammonite used for blasting operations at sections, pits, in underground production bottomholes of class II during drill holes, wells, and chambers loading in all climatic zones with temperature from minus 50 to plus 50°C on rocks of any strength and ores of any composition. Grammonit contains TNT in the form of flakes, or granulated, or a mixture thereof, granulated ammonium nitrate and mononitrotoluene at the components ratio, wt %: 17.0-23.0 for TNT, 0.01-3.0 for mononitrotoluene, the rest up to - granulated ammonium nitrate. M-grade granulotol is included into the composition as granulated trotyl. Mononitrotoluene includes para-mononitrotoluene (p-MNT), or ortho-mononitrotoluene (o-MNT), or meta-mononitrotoluene (m-MNT) or mixtures thereof. During explosive transformation of grammonite, total produced gas harm is less than 63 l/kg.

EFFECT: invention is aimed at creation of a safely-manufactured explosive and handling thereof.
