Mixed explosive for fluidized beds and preparation method thereof

The invention relates to the technical field of engineering blasting, and particularly discloses a mixed explosive for fluidized beds. The mixed explosive is prepared from the following raw materials,by weight: 73 to 76% of ammonium nitrate, 1 to 4% of urea, 15 to 18% of water, 3.5 to 5% of diesel oil and 1 to 2.5% of an emulsifier. The invention also discloses a preparation method of the mixed explosive for the fluidized beds. According to the preparation method, based on the gap characteristic of an oil-phase material and the compatibility with the emulsifier, the using amount is adjusted,the isolation protection effect is enhanced, an additive is selected as a chemical reaction inhibitor according to the principle that the additive is soluble in water and does not react with other components, oil film strength is enhanced by changing the oil phase composition, and a certain inhibition effect is achieved on the reaction of explosives and sulphide ores. 本发明涉及工程爆破技术领域，具体公开了一种用于流化床的混装炸药，包括以下重量百分比的原料：硝酸铵73-76%、
