ON THE RELATIONSHIP BETWEEN DETONATION VELOCITY AND THE TIME OF GASIFICATION, POREMIT 1A INDUSTRIAL EMULSION EXPLOSIVE AS AN EXAMPLE

Abstract

The article presents the results of experimental-industrial tests carried out in the framework of the research expedition in the integrated-concentrating plant "Uralasbest". To study the detonation characteristics "Methods of measurement the explosives’
detonation velocity by rheostatic method, acceleration of seismic vibrations and pressure on the front shock air wave using the "DATATRAP II™ DATA/VOD RECORDER" meter of detonation velocity were used The study on detonation characteristics of industrial emulsion explosives poremit 1A, in field conditions, using 8-channel high speed data logger "DATATRAP II™".100 mm Measurements of detonation velocity were performed in a paired core blasting Ø100 mm charges, with wall thickness of 7
mm and 1000 mm length. In the experimental-industrial tests of the dependence of detonation velocity from the time of emulsion explosives gasification and solutions of the problems associated with obtaining essential detonation characteristics in blasting operations are proposed.
