Embodiment 1

[0032] Embodiment one: A method of making liquid oxygen explosives:

[0033] Such as figure 1 Shown, a kind of method of making liquid oxygen explosive comprises the steps:

[0034] (1) Place a funnel vertically in the center of the metal sheet open container, and set holes through the pipe wall in the part of the funnel tube in contact with the combustibles in a form of sparse bottom and dense top, and the lower part of the funnel is a closed pointed tip;

[0035] (2) Install the detonator in the area where the combustibles are filled in the container;

[0036] (3), combustibles are poured into the container for charging, and after the charging is completed, the blast hole is backfilled; the combustibles are 50%-70% coal powder and 50%-30% wet sawdust by mass percentage or combustible fibers, the wet sawdust contains 5% sodium chloride solution, the concentration of the sodium chloride solution is 20%; the diameter of the coal powder is 20-30 microns;

[0037] (4) Insert...

Abstract

The invention discloses a method for preparing a liquid oxygen explosive, belonging to a method for preparing or treating an explosive composition. The method comprises the following steps of: (1) vertically placing a funnel at the center of a pressure container, and forming a hole in a part where a funnel pipe is in contact with a combustible material, wherein the hole passes through the wall of the funnel pipe, and the lower part of the funnel is sealed; (2) arranging a primer detonator in a combustible material filling region in the pressure container; (3) pouring the combustible material into the container, charging powder, and backfilling a blast hole after the powder charging operation is finished; (4) inserting a thin-wall gas guide tube into the funnel, pouring liquid oxygen into the funnel, and pulling out the thin-wall gas guide tube and the funnel after the liquid oxygen filling operation is finished, wherein the side of the bottom of the thin-wall gas guide tube is provided with a plurality of small holes; and (5) filling a gap generated by the funnel to be solid again to obtain the liquid oxygen explosive. The method disclosed by the invention has the advantages that gaseous oxygen accumulated at the bottom can be effectively discharged, so that liquid oxygen can be favorably filled and can not be wasted; and the static electricity generating probability, namely the accidental explosion probability, is reduced, so that the preparation safety is ensured.

Description

technical field [0001] The invention belongs to a method for preparing or treating an explosive composition, in particular to a method for making a liquid oxygen explosive. Background technique [0002] Explosives that use combustible porous substances as absorbents and are saturated with liquid oxygen are called liquid oxygen explosives. Liquid oxygen explosives produce a variety of explosive effects, which mainly depend on the following factors: the type and density of the absorbent, the size of the fibers (for brick-like absorbents), the degree of comminution (for powder-like absorbents) ), and the content of liquid oxygen in the explosive mixture at the time of explosion. [0003] The principle of liquid oxygen explosive explosion is the same as that of ordinary explosives, that is, liquid oxygen is easily evaporated (1L of liquid oxygen can become 800 liters of gaseous oxygen), so that the absorbent is oxidized instantly to generate a large amount of carbon dioxide, wa...
