Abstract:
     This invention relates to an emulsified explosive used for coal mine. The sensitization of the explosive is due to organic foaming agent. The sensitized gas bubbles in the emulsified explosive used for coal mine are very fine and uniformly distributed. The time for sensitization is short. The after-effect of sensitization is little. The natural storage period of this explosive may be over one year. Its explosive property and safe property is better than that kind of emulsified explosive used for coal mine, which is made of pearlite or sodium nitrite. The cost of organic foaming agent used in this invention is 11% of that of pearlite. The explosive series of this invention may be used in that kind of coal mine where risk due to marsh gas and coal dust exist. Its safety property is higher.
