PACKING

Polypropylene bags with polyethylene inserts or paper bags with polyethylene inserts weighing grammonite no more than 40 kg.

SCOPE

For conducting explosive works on open-cast mountain minings with manual and mechanized (except pneumatic) loading of the dry and wet (dehydrated) wells, shots and cameras. Use in the flooded wells with landlocked water taking into account time of stay of grammonite in these conditions, is possible no more than 24 hours. It is recommended to application in mountain and explosive works on breeds of average and high fortress, gaseous products of explosion contain smaller quantity of toxic components.
