EXPERIMENTAL STUDY OF DETONATION CHARACTERISTICS OF INDUSTRIAL EMULSION EXPLOSIVES NPGM PRODUCTED BY COMPANY "NIPIGORMASH"

Abstract

In the industrial conditions of the Eldorado quarry,
OOO Sovrudnik, instrumental measurements of the
detonation velocity of the industrial emulsion explosive NPGM-100 and NPGM-70 were carried
out to analyze the detonation characteristics of
explosives and to establish their compliance with
the requirements of technical conditions. Measurements were made in technological wells during
the production of mass explosions in the quarry,
using foreign equipment DataTrap II Data/VOD
Recorder of the Canadian "MREL Group of Companies Limited", based on a modern version of the
rheostat measurement method. The study found that
the introduction of a dry phase of 30% (at a density
of 1.2 g/cm3
) in the composition of the NPGM contributes to an increase in the detonation velocity of
explosives. The measurements also showed an increase in the detonation characteristics of the explosive with a decrease in its density to a value of
=1.17 g/cm3
. Therefore, with a decrease in the
density to normal values (=1.16-1.17 g/cm3
), we
can expect the detonation velocity, which is stated
in the technical specifications.
