The invention relates to explosive compositions of borehole and blast-hole charges. An explosive composition includes ammonium nitrate in granulated or crystalline forms or in the form of mixture of both forms and water and oil emulsion, which is composed of liquid petroleum product, ammonium nitrate, emulsifier and water. To increase a detonation ability, physical stability and reduce toxicity the water and oil emulsion contains in addition carbamide, and as emulsifier, derivatives of alkylpolyethylene glycol ethers or polyoxy ethylated ethers of isotridecyl alcohol, and mono- or dialkylphenyloxypolyethylene glycol ethers or polyoxy ethylated ethers of fatty acids are used. |
