Abstract:
     This invention relates to an explosive used in demolition engineering of mine where explosion risk due to coal dust or marsh gas exists. It is a kind of ammonium nitrate explosive which is made up of oxidizing agent, proper amt. of flame-eliminating agent, flammable agent, water, emulsifier, small amt. of regulator which participates directly in explosion reaction and regulates the density of foam carrier. If necessary, little amt. of explosive sensitizer may be added. All the constituents are formulated under a condition of zero oxygen balance. The dry ammonium nitrate explosive possesses sensible bubbles, granular form medium density, and high safety. This invention possesses the features of wide-spread source of raw material, simplicity in processing technology, stability in quality, easiness of filling powder rolls. It possesses both high safety to marsh gas and proper demolish property.
