Abstract

The invention discloses a powdery emulsion ammonium nitrate fuel oil explosive allowed to be used in coal mines and a preparation technology thereof, which is compounded and prepared by using rock powdery emulsion explosive which has good characteristics of high sensitivity to initiation, high detonation velocity and high explosive grading, to mix with ammonium nitrate fuel oil explosive containing a certain amount of flame inhibitor, wherein, the rock powdery emulsion explosive accounts for 28 percent to 32 percent of the total weight of the explosive and the fire-resistant ammonium nitrate fuel oil explosive accounts for 68 percent to 72 percent of the total weight of the explosive. The rock powdery emulsion explosive is an industrial explosive like powder formed from water-in-oil type latex base material which is sprayed and dried. The rock powdery emulsion explosive can be mixed into ordinary ammonium nitrate fuel oil explosive to replace trinitrotoluene and plays a sensitization role in the explosive to increase the explosive performance of compound explosive. The grade I and the grade II explosive prescriptions of the invention are respectively applicable to the excavating working faces of low-methane rock or low-methane coal beds and mines and the preparation technology thereof is applicable to the discontinuous or continuous automatic production of the powdery emulsion ammonium nitrate fuel oil explosive used in the coal mines.

Description

technical field

[0001] The invention relates to a coal mine permitted powdery mixed explosive, in particular to a coal mine permitted powdery emulsified ammonium oil explosive which does not contain TNT and has high explosive performance and a preparation method of the explosive. Background technique

[0002] At present, the domestically produced powder explosives for coal mines mainly include ammonium-tetrade oil explosives for coal mines, powder emulsion explosives for coal mines, and ammonium oil explosives for coal mines. The advantages of these explosives are that they do not contain TNT or contain less TNT. , less harmful to the environment and human health, good production safety, and relatively low cost of raw materials. However, these explosives all have many shortcomings and deficiencies: the ammonium-ladder oil explosives allowed in coal mines are ladder-containing explosives, and are products that are about to be eliminated; The cost is high, the storage stabili...
