Cartridged and granulated explosive substances of grade Ukrainit for underground mines

Abstract

The paper presents a part of set of operations on change of underground mines for trotyl-free explosive substances (ES). The purpose is development and introduction granulated and cartridged trotylfree explosive substances with high detonation and technological parameters in the underground mines of Ukraine. The unique structure of fuel phase and unparalleled technology of obtaining of highly-stable granulated ES Ukrainit-ANFO on the basis of agrarian ammonium nitrate is created. Ukrainit-ANFO is intended for pneumocharging of holes and wells of small diameter, possess high level working capacity and safety, minimum toxicity of explosion products, long guarantee period (3 months). Scientifically based approach to creation of formulas and technology of obtaining cartridged emulsion ES Ukrainit-P is implemented. According to functional purpose, cartridges Ukrainit-P are universal and intended for formation blast-hole charges, for initiation (as intermediate detonator) of charges of emulsion and granulated ES in wells and holes of any diameter, and also for crushing of oversize material. High parameters of working capacity and small critical diameter allow production of cartridges of any diameter (from 32 mm). The range and technology of developed of granulated and cartridged ES of grade Ukrainit in combination with filling emulsion ES Ukrainit provide complex solution of problem of underground mines Ukraine change for trotyl-free ES.
