FIELD: explosive substances.

SUBSTANCE: invention relates to emulsion explosive substances of type "water-in-oil" for carrying out explosive works on opened layers. Proposed emulsion explosive composition contains the following components, %: sodium nitrate or calcium nitrate, 2-16; water, 2-10; oil or mazut, 0.5-8; sodium nitrite, 0.1-0.5; saltpeter ammonium nitrate granules, 25-75; magnesium nitrate, 0.1-0.3; emulsifier, 0.5-3; ammonium nitrate, up to 100. Method for preparing composition involves preliminary mixing saltpeter ammonium nitrate with magnesium nitrate. Invention provides enhancing effectiveness based on decreasing loss in cracked rocks in pores filling.

EFFECT: improved and valuable properties of composition.
