Abstract
The invention relates to a high-energy safe composite explosive. According to the invention, the explosive comprises a high-energy insensitive emulsion explosive filled in a packaging material with an energy-accumulation bottom, a low-energy sensitive emulsion explosive which is filled and wrapped in, and a sealing. Independently, no matter how the explosive property is, the low-energy sensitive emulsion explosive at least comprises a columnar body with a diameter of 32mm and a length of 80mm, and the cross-section of the low-energy sensitive emulsion explosive is substantially superposed with the cross-section of the high-energy insensitive emulsion explosive, and the distance between the low-energy sensitive emulsion explosive and the sealing is at most 20mm.
Description
Technical field
The present invention relates to the industrial explosive in the quick-fried product of the people, it comprises not having and injects the responsive emulsion explosive of the low energy with reliable cap-sensitivity in the high-energy insensitive emulsion explosive of cap-sensitivity, more specifically, the present invention relates to its type and can be called the high-energy safe binary explosive usually.
Background technology
" catalogue (basis in 2011) is instructed in industry restructuring " that the National Development and Reform Commission promulgates spells out " high-performance safety type industrial explosive " and belongs to the quick-fried product of the encouragement class people, and products such as " an-tnt explosives " belongs to the quick-fried product of the people out of category (the quick-fried industry of the people forced to eliminate in 2008).
At home in the industrial explosive production field, at present, mainly contain the industrial explosive of two kinds of mode of manufacture: a kind of is the package-type industrial explosive that enterprise model is produced, the detonation property height, but have certain cap-sensitivity and mechanical sensitivity, there are certain potential safety hazard in storage and transportation; Another kind is the filling type industrial explosive of on-site mixed mode of manufacture, do not have cap-sensitivity and mechanical sensitivity, but detonation property is low.
Awarded to the United States Patent (USP) 00815605.0 of The Ensign-Bickford Company on June 18th, 2003, being entitled as " having the explosive of imbedding body " discloses a kind of explosive loading that has the first explosive material of main part and be embedded in the discrete bodies of second material wherein, its explosive loading main raw is PETN and TNT, all understand very much in this area, PETN and TNT belong to the energetic material of forbidding joining in the industrial explosive.
Summary of the invention
High-energy safe binary explosive provided by the invention comprises: (in the specified scheme do not have this structure), wrapping material, high-energy insensitive emulsion explosive, the responsive emulsion explosive of low energy at the bottom of the cumulative, seal composition.
Principle of the present invention is: high-energy insensitive emulsion explosive control is packed under high-density, half sensitization state in the wrapping material, utilize the high-energy insensitive emulsion explosive not possess cap-sensitivity but bulk strength can obtain high-density the time, thereby improve the output energy; Again the responsive emulsion explosive of the low energy of low density, full sensitization state is injected the high-energy insensitive emulsion explosive, by its reliable cap-sensitivity by blasting cap initiation after, the high-energy insensitive emulsion explosive is carried out heavy initiation, make it obtain splendid detonation state, and can improve its output energy again.Because low energy sensitivity emulsion explosive is coated in the high-energy insensitive emulsion explosive, utilize the insensitiveness and stability of high-energy insensitive emulsion explosive, improve the security of storing and transporting.
According to an aspect of the present invention: detonated by common No. 8 industrial detonators and enough energy that detonates are provided for guaranteeing the responsive emulsion explosive of low energy, the responsive emulsion explosive of low energy has 32 millimeters of diameters and 80 millimeters columns of length at least, in specified scheme, its profile is irregular column, but its functional parts has 80 millimeters of 32 millimeters of diameters and length at least.
According to another aspect of the present invention: effectively contact for guaranteeing the responsive emulsion explosive of detonator and low energy, the responsive emulsion explosive of low energy cross section overlaps substantially with high-energy insensitive emulsion explosive kernel of section, and from sealing 20 millimeters at the most of distances.
Description of drawings
The present invention will illustrate by way of compared with accompanying drawings and combined with example.
Fig. 1 is structure cross-sectional schematic of the present invention, and Fig. 2 is the A-A cross-section cutaway view at Fig. 1.

Below in conjunction with accompanying drawing by the further instruction of the present invention of embodiment.
Preferred embodiment
Present embodiment is in the wrapping material ⑵ of ⑴ at the bottom of the band cumulative (not having this structure in the specified scheme), fill high-energy insensitive emulsion explosive ⑶, adopt the powder charge pipe that the responsive emulsion explosive ⑷ of low energy is injected high-energy insensitive emulsion explosive ⑶ then, stop powder charge during apart from 20 millimeters of high-energy insensitive emulsion explosive ⑶ powder, utilize the effect of sealing ⑸ that the responsive emulsion explosive ⑷ of low energy is coated among the high-energy insensitive emulsion explosive ⑶.
In conjunction with Fig. 1 and Fig. 2, in the above-described embodiments, the responsive emulsion explosive ⑷ of low energy has 32 millimeters of diameters and 80 millimeters columns of length at least, in specified scheme, its profile is irregular column, but its functional parts has 80 millimeters of 32 millimeters of diameters and length at least, and the responsive emulsion explosive ⑷ of low energy cross section overlaps substantially with high-energy insensitive emulsion explosive ⑶ kernel of section, and from sealing ⑸ apart from 20 millimeters at the most.
To seal ⑸ with special-purpose drilling tool during use punctures, No. 8 industrial detonators are inserted among the responsive emulsion explosive ⑷ of low energy along the center, the responsive emulsion explosive ⑷ of the low energy of detonating behind the blasting cap detonation, ⑶ carries out heavy initiation to the high-energy insensitive emulsion explosive, make high-energy insensitive emulsion explosive ⑶ be in a kind of high detonation state, and externally export beta maximum energy.
Disclosed all features in this specification sheets except the feature of mutual repulsion, all can make up by any way.
Disclosed arbitrary feature in this specification sheets (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.Unless i.e.: special narration, each feature is an example in a series of equivalences or the similar characteristics.
