preparation example Construction
[0017] A preparation method for heavy ammonium oil explosives, comprising the following steps:
[0018] The first step is to mix porous granular ammonium nitrate with a mass percentage of 94% to 95% and 5% to 6% diesel oil and soak in oil for more than 24 hours, which is a porous granular ammonium oil explosive;
[0019] In the second step, the mineral base oil with a mass percentage of 60% to 80% and the microcrystallinewax of 20% to 40% are heated to 85° C. to 95° C., stirred and mixed to prepare an oil phase and kept warm;
[0020] The third step is to add 10% to 30% of the oil phase prepared and kept at 80°C to 90°C with a mass percentage of 10% to 30% into the porous granular ammonium oil explosive of 70% to 90%, and keep stirring to make it evenly mixed, which is Heavy ammonium oil explosives.
[0021] The present invention will be further illustrated below by specific examples.
Embodiment 1
[0023] Configure porous granular ammonium oil explosives, add 5.5% diesel oil to the porous granular ammonium nitrate with a mass percentage of 94.5%, mix evenly, and soak in oil for 24 hours.
[0024] The oil phase is configured, and the mass percentage is 70% of mineral base oil and 30% of microcrystalline wax heated to 95° C. for melting and mixing and kept at 90° C.
[0025] 10% by mass of the oil phase is added to 90% of the porous granular ammonium oil explosive, stirred evenly, and cooled to room temperature to form the heavy ammonium oil explosive.
[0026] According to the performance test method of GB / T17583 "Porous Granular Ammonium Fuel Explosive", the detonation velocity is 2878m / s, and the blast is 15.4mm.
Embodiment 2
[0028] Configure porous granular ammonium oil explosives, add 5.5% diesel oil to the porous granular ammonium nitrate with a mass percentage of 94.5%, mix evenly, and soak in oil for 24 hours.
[0029] The oil phase is configured, and the mass percentage is 70% of mineral base oil and 30% of microcrystalline wax heated to 95° C. for melting and mixing and kept at 90° C.
[0030] 20% by mass of the oil phase is added to 80% porous granular ammonium oil explosives, stirred evenly, and cooled to room temperature to form heavy ammonium oil explosives.
[0031] According to the performance test method of GB / T17583 "Porous Granular Ammonium Fuel Explosive", the detonation velocity is 2892m / s and the blast is 15.7mm.

Abstract
The invention discloses a heavy ammoniumnitrate-fuel oil explosive and a preparation method thereof. The heavy ammoniumnitrate-fuel oil explosive is an explosive added with 10-30% of mixture of mineral base oil and microcrystallinewax by mass. The specific preparation method comprises the following steps: (I) mixing 94-95% of porous granular ammoniumnitrate and 5-6% of diesel oil by mass, and performing oil immersion for over 24 hours to obtain a porous granular ammonium nitrate-fuel oil explosive; (II) heating 60-80% of mineral base oil and 20-40% of microcrystallinewax by mass to 85-95 DEG C, stirring and mixing to prepare an oil phase, and preserving heat; and (III) adding 10-30% of oil phase by mass prepared and kept at 80-90 DEG C into 70-90% of porous granular ammonium nitrate-fuel oil explosive, and continuously stirring for uniformly mixing to obtain the heavy ammonium nitrate-fuel oil explosive. In the invention, major hazard sources of the forepart process of an emulsion explosion production line are removed, and the intrinsic safety is actually realized.
Description
technical field [0001] The invention belongs to the technical field of industrial explosives, in particular to a heavy ammonium oil explosive and a preparation method thereof. Background technique [0002] Heavy ammonium oil explosives combines the advantages of ammonium oil explosives and emulsion explosives. It is easy to operate during blasting operations and has a certain water resistance. It has been widely used, especially in my country's current mines. It adopts the blasting method of pneumatic loading heavy ammonium oil explosives. [0003] GB / T17582-2011 "Classification and Naming Rules for Industrial Explosives" clearly states that industrial explosives made by mixing emulsified matrix and porous granular ammonium oil explosives in different proportions are emulsified ammonium oil explosives, referred to as heavy ammonium oil explosives. The emulsification matrix mentioned in the standard is produced by the front stage of the production of emulsion explosives, that...
