摘要： PROBLEM TO BE SOLVED: To obtain an explosive directly fillable into a blast hole, by mixing a water-in-oil type emulsion containing an aqueous solution of an oxidizing agent, an oil and an emulsifying agent with a specific amount of a minute hollow body having a specified particle diameter and a prescribed amount of a hollow body and forming a granule. SOLUTION: This explosive composition is obtained by mixing a water-in-oil type emulsion comprising an aqueous solution of an oxidizing agent, an oil and an emulsifying agent with 1-20 wt.% of a minute hollow body made of glass or a resin having 0.01-0.3 mm particle diameter and 1-40 wt.% of a hollow body composed of pumicious sand, alumina, expanded alumina, etc., having 0.3-5.0 mm particle diameter and forming the mixture into a granule having 0.3-20.0 mm particle diameter. The water-in-oil type emulsion is obtained by preparing an emulsion so that the amount of the aqueous solution containing the oxidizing agent such as ammonium nitrate or the like, an auxiliary desensitizer such as monomethylamine nitrate and 5-40 wt.% of water is 60-98 wt.% in the composition, the amount of the oil such as a paraffin wax or the like is 0.5-15 wt.% in the emulsion and the amount of the emulsifying agent such as ammonium stearate or the like is 0.5-15 wt.% in the emulsion.

摘要： PROBLEM TO BE SOLVED: To provide an emulsion explosive which is improved in impact resistance and hardly gives rise to misfire and remaining without impairing the intrinsic initiation sensitivity possessed by the W/O type emulsion explosive. SOLUTION: The waterdrop-in-oil type emulsion explosive consisting of an aqueous oxidizing agent solution, oils, emulsifiers and microhollow spherical bodies is prepared by using the glass microhollow spherical bodies of >=45 vol.% in the survival rate when the microhollow spherical bodies are pressurized to 13.79 MPa (2,000 psi) under true specific gravity ranging from 0.10 to 0.35 as the microhollow spherical bodies.

摘要： PURPOSE: To obtain an explosive which is prevented from being solidified by using porous prilled ammonium nitrate, a fuel oil and a thickening stabilizer having a specified average particle size as the components of the explosive. CONSTITUTION: A high temp. ammonium nitrate molten liquid having an adjusted concn. is jetted with a jet granulator, and then, dried and cooled to prepare porous prilled ammonium nitrate having an about 0.5 to 2.0mm average granule size, an about 7 to 24% oil absorption ratio and an about 4 to 25 hardness. Subsequently, the porous prilled ammonium nitrate is charged into a mixer such as kneader, and then, a fuel oil such as No.2 gas oil is added to the prilled ammonium nitrate and they are mixed together at about 20 to 120rpm for about 2 to 20min to obtain a mixture. Thereafter, a thickening stabilizer having a 0.01 to 3mm average particle size, such as poly(sodium acrylate) is added to the resultant mixture and they are mixed together and uniformized at about 20 to 120rpm for about 1 to 20min to obtain the objective granular explosive contg. about 70 to 97wt.% of the porous prilled ammonium nitrate, about 2.5 to 25wt.% of the fuel oil, 0.01 to 4.5wt.% of the thickening stabilizer and further, if necessary, other additives such as an antistatic agent and another oxidizing agent.
