Abstract

1. Эмульсионный взрывчатый состав, предназначенный для формирования шпуровых зарядов, включающий воду, аммиачную и натриевую или кальциевую селитру в качестве окислительной фазы, а также углеводородную фазу, отличающийся тем, что в состав ЭВВ введен карбамид, а в составе углеводородной фазы взамен масел индустриальных или дизельного топлива использован расплав парафина мелкокристаллического в чистом виде или с добавкой церезина при любом соотношении указанных компонентов между собой, или только церезина в смеси с эмульгатором для промышленных эмульсионных взрывчатых веществ индивидуально или с эмульгатором для промышленных эмульсионных взрывчатых веществ в сочетании с добавкой из канифоли талловой или канифоли живичной сосновой, или их смеси при любом соотношении указанных марок канифоли между собой в диапазоне температур ведения технологического процесса изготовления ЭВВ от 65°С до 130°С, а в качестве сенсибилизатора применен водный раствор нитрита натрия в сочетании с полимерными микросферами, введенными взамен стеклянных, при любых соотношениях компонентов между собой или только полимерные микросферы, или только водный раствор нитрита натрия, причем указанные компоненты взяты для достижения нормируемой плотности 1,00÷1,20 г/смв следующем соотношении, мас.%:2. Эмульсионный взрывчатый состав по п.1, отличающийся тем, что в качестве сенсибилизатора может содержать полимерные микросферы в чистом виде или в сочетании с водным раствором нитрита натрия при любых соотношениях указанных компонентов между собой или только водный раствор нитрита натрия.1. An emulsion explosive composition intended for the formation of borehole charges, including water, ammonia and sodium or calcium nitrate as an oxidizing phase, as well as a hydrocarbon phase, characterized in that carbamide is introduced into the emulsion explosives and instead of industrial oils in the hydrocarbon phase diesel fuel used melt crystalline paraffin in pure form or with the addition of ceresin at any ratio of these components to each other, or only ceresin mixed with an emulsifier for industrial industrial emulsion explosives individually or with an emulsifier for industrial emulsion explosives in combination with the addition of tall oil rosin or pine gum rosin, or a mixture thereof at any ratio of these grades of rosin to each other in the temperature range of the technological process for the manufacture of emulsion explosives from 65 ° C to 130 ° C, and as a sensitizer an aqueous solution of sodium nitrite was used in combination with polymer microspheres introduced instead of glass, at any ratios of components of only a row or polymeric microspheres or only an aqueous solution of sodium nitrite, and said components are taken to achieve the normalized density 1.00 ÷ 1.20 g / CMB following ratio, wt.%: 2. The emulsion explosive composition according to claim 1, characterized in that the sensitizer may contain polymer microspheres in pure form or in combination with an aqueous solution of sodium nitrite at any ratios of these components to each other or only an aqueous solution of sodium nitrite.
