ABSTRACT
Objective is to study
explosive and safety properties of the samples of domestic safety emulsion
explosive of class IV.
Research methods. To determine explosive
characteristics of the sticked emulsion
substances, laboratory methods developed at the State Enterprise “Research
and Production Association “Pavlohrad Chemical
Plant” (SE “RPA “PCP”) are applied. Detonation velocity of the charges of
the emulsion explosives was defined involving the
“Voodmate” device. Safety properties of the test
samples of the emulsion explosives were analyzed in the experiment mine roadway.
Findings. The developed composition
of the domestic safety emulsion explosive has been tested
in terms of the specification of both explosive and safety properties.
Test results have
made it possible to define that the explosive characteristics of the tested
safety emulsion explosives (SEE) are not to be inferior than
the trotyl-containing safety explosives of class
IV. The tests of safety properties carried out in the mine roadway have
demonstrated that the SEE test samples belong to class IV.
Originality. Explosive and
safety characteristics of the samples of domestic safety emulsion
explosives developed at the SE “RPA “PCP” have been identified. The safety
emulsion explosives preserve the explosive and safety properties not to be
inferior than the trotyl-containing
analogues in terms of the non-available toxic component.
Practical
implications. The manufactured samples of the safety emulsion
explosives were tested to define their explosive
and safety characteristics. The obtained results concerning the
manufacturing of the samples of the safety emulsion explosives may be used for further production of domestic
admissible emulsion explosives of class IV.
Key words: safety
properties, emulsion explosives, ignition quality, experiment mine roadway,
detonation velocity.
