Granular industrial explosive "GRAMMONITE"
"Grammonite" is an industrial explosive manufactured by mechanized means at stationary production facilities. It is intended for manual and mechanized loading of blastholes and boreholes during drilling and blasting operations.
Features
Available in the following grades:
• 79/21 - a mixture of ammonium nitrate granules and granulotol;
• 15 - a mixture of ammonium nitrate granules, granulotol, and diesel fuel;
• 10 and 5 - a mixture of ammonium nitrate granules, granulotol, diesel fuel, and aluminum powder;
• E - a mixture of ammonium nitrate granules, granulotol, and emulsion.

Application:
The industrial explosive "Grammonite" belongs to Class 2 of non-permitted industrial explosives and is used for blasting operations in surface and underground workings where there are no flammable gases and explosive coal (shale) dust, or where inertization of the face area is provided. "Grammonite" is designed for breaking rocks with a hardness coefficient of f=6-20 on the Protodyakonov scale in dry blastholes and boreholes. Loading of boreholes is permitted at temperatures down to -40°C.
