Complex approach to implementation of filling emulsion explosives Ukrainit in underground conditions

Abstract

Filling emulsion explosives are safe alternative to trotyl-containing materials. The paper objective is creation and implementation of complex approach to introduction of filling emulsion explosives with high explosion and technological parameters in underground mines of Ukraine. Compositions and technologies of production of filling emulsion explosives Ukrainit-PP-2 with controlled parameters of dispersion, viscosity, gas generation speed are developed. The small-size and selfpropelled mixing and charging machinery for holes charging in drifting faces and blind drifts is developed and implemented. The advanced technology of formation and reliable holding of charges of emulsion explosives in vertical wells with a diameter more than 89 mm is tested. The selfpropelled and block-modular mixing and charging machinery is developed for charging of drill ring of well from the mouth of face. The diagram of logistics and technical means of transportation of components of emulsion explosives from a surface in mine to the area of consumption is developed. The complex approach allows increasing efficiency and safety of explosive works in underground conditions and abandoning application of trotyl-containing explosives.
