Abstract: Laboratory tests of nanostructured foam-gel compositions as a stemming material were carried out. The rock was imitated by cement-sand models, the borehole charge by a blasting cap with an equivalent mass of explosives and the heat of the explosion. The foam gel was filled in ampoules, which are used to make a stemming. The comparison was made with a sifted sand stemming. The obtained results of the time of ejection of explosion products from the hole, the time of destruction of the models, and the analysis of the crushed product of cement-sand models show that the nanostructured composition as a stemming provides an increase in the efficiency of the explosive charge in the model.

Key words: foam gel nanostructured composition multiplicity stability stemming borehole explosion
