Description

  The present invention relates to an explosive treatment method used for treating explosives such as explosives and explosives, for example.

  Conventionally, when explosives such as explosives and explosives described above are treated, for example, a method of dumping in an incinerator or blasting using a detonator is employed (for example, see Patent Document 1). When dumping into the furnace, in order to ensure safety, it is necessary to dump a small amount at a time and work efficiency is poor. On the other hand, when detonating with a detonator, there is a risk of connecting the detonator to the explosive. Accompanied by.

Therefore, in order to deal with such a problem, in recent years, a processing method in which explosives are directly irradiated with laser light to cause initiation combustion has been studied (see, for example, Patent Document 2).
Japanese Patent Laying-Open No. 2005-233459 JP 2001-82900 A

  However, in the above-described processing method of directly irradiating the explosive with laser light, the explosive cannot be combusted unless the high-power laser light is irradiated. However, it has been a problem to solve this problem.

  The present invention has been made paying attention to the above-described conventional problems, and provides a method for treating explosives that can be burned safely and efficiently completely without changing explosives into unstable substances. It is intended to provide.

  In the present invention, when explosives such as explosives and explosives are treated, a fire type made of metal or carbon black is placed in contact with the explosives, and then laser light is irradiated to the fire type. The structure of this explosives treatment method is a means for solving the above-described conventional problems.

  In the present invention, when explosives such as explosives and explosives are treated, when a laser beam is irradiated to a fire type consisting of a metal or carbon black placed in contact with the explosive, the fire type is brought into a high temperature state in the process of melting the fire type. Or the sparks scatter from the sparks and function reliably as the sparks of the explosive ignition, so the explosives will burn completely without changing to unstable materials.

  In this process, there is no need to perform a dumping operation for dividing explosives or a connection operation of a detonator, so that the explosives can be completely burned safely and efficiently.

  According to the explosive treatment method of the present invention, since it is configured as described above, it is possible to ensure safety, and to completely burn the explosive without changing it to an unstable substance. In addition, it is possible to achieve an excellent effect that it is possible to improve the work efficiency.

  In the method for treating explosives according to the present invention, the fire type forms a container that can contain explosives, and the container type fire type that contains the explosives is irradiated with laser light, or the fire type is powdery. Or the structure which irradiates a laser beam with respect to the powder type or fine piece-shaped fire type which comprised the fine piece shape and was covered with the explosive material is employable.

  When the former fire type is in the shape of a container, the explosive and fire type can be brought into contact with each other by containing the explosive in the fire type, and when the latter fire type is in the form of powder or fine pieces By applying this fire type to the explosive, the explosive and the fire type can be brought into contact with each other. Thus, in any case, it is possible to bring the fire type into contact with the explosive with a simple operation. Is ensured and work efficiency is improved.

  Moreover, in the processing method of the explosive material which concerns on this invention, it can be set as the structure which uses any of an iron material, an aluminum alloy material, and a copper alloy material as a metal for fire types.

  In this case, the iron material containing a large amount of carbon scatters a large amount of sparks at the stage where the laser beam is irradiated and becomes a high temperature state. Therefore, for example, SS400 (general structural rolled steel) and S35C ( It is desirable to use an iron material such as a carbon steel material for machine structure) or SCM435 (chromium molybdenum steel material).

  On the other hand, when the metal for fire type is an aluminum alloy material, for example, A5052 (Al-Mg alloy) can be adopted, and when the metal for fire type is a copper alloy material, for example, C5191 (phosphorus). Bronze) can be employed, and in any case, irradiation with a high-power laser beam is required as compared with the case where the fire metal is an iron material.

  Furthermore, in the method for treating explosives according to the present invention, when an iron material is used as a metal for a fire type, the amount thereof is not particularly limited although it depends on the type and amount of explosives, and the ignitability to explosives. From this point of view, for example, a trace amount of 1 g or less may be used. As an example, 75 g (φ30 × 80 mm) of TNT explosive was used as the explosive, and an experiment of the treatment method was conducted using 27 g of iron (φ30 × 5 mm). I was able to.

  EXAMPLES Hereinafter, although an Example demonstrates this invention still in detail, this invention is not limited to a following example.

  FIG. 1 shows a situation where explosives are treated using a method for treating explosives according to an embodiment of the present invention.

  As shown in FIG. 1, a cylinder 2 made of silicon rubber is filled with explosives (TNT explosive) 3, and one open end of the cylinder 2 is closed with a disc 4 as a fire type made of iron (SS400). Specimen 1 was manufactured. At this time, the disc 4 was attached to one open end of the cylindrical body 2 so as to contact the explosive 3.

  In this example, the diameter d of the disk 4 as a fire type was φ30 mm, and the thickness t was 5 mm. Moreover, the diameter D of the cylinder 2 was set to 30 mm, and the length L was set to 80 mm. Furthermore, while the amount of TNT explosive 3 filled in the cylinder 2 was 90 g, the amount of iron material of the disc 4 as a fire type was 28 g.

  When the disk 4 is irradiated with laser light (YAG laser light having a beam diameter of 3.5 mm), the disk 4 is melted. In the process of melting the disk 4 made of iron, the disk 4 is heated to a high temperature state. Since a lot of sparks are scattered at this stage, the disc 4 functions as an ignition source of the explosive 3 reliably. As a result, the explosive 3 does not change into an unstable substance and is completely It will burn.

  In the above-described processing, there is no need for a dumping operation in which the explosive 3 is subdivided or a connection work of a detonator, so that the explosive 3 can be completely burned safely and efficiently.

  In the above-described embodiment, the open end of the cylinder 2 filled with the explosive 3 is closed with the disc 4 made of iron as a fire type, so that the disc 4 and the explosive 3 are brought into contact with each other. As another configuration, for example, as shown in FIG. 2, the container 14 made of iron (SS400) is used as a fire, and the explosive 3 is accommodated in the container 14 so that the container 14 and the explosive 3 are brought into contact with each other. In addition to the above, as shown in FIG. 3, the powder 24 (including fine pieces) made of iron (SS400) is used as a fire type, and the powder 24 is applied to the explosive 3, whereby the explosive 3 You may make it contact.

  In the case where the fire type is a container 14 made of an iron material, when the container 14 containing the explosive 3 is irradiated with laser light (YAG laser light with a beam diameter of φ3.5 mm) 5, the container 14 is melted at a high temperature. Since a lot of sparks are scattered at the stage when the state is reached, the container 14 functions reliably as an ignition type of the explosive 3 and the explosive 3 is completely burned.

  On the other hand, when the powder 24 made of iron is used as the fire type, when the powder 24 applied to the explosive 3 is irradiated with laser light (YAG laser light having a beam diameter of 3.5 mm) 5, the powder 24 is Since a lot of sparks are scattered at the stage where the temperature is high, the powder 24 functions as an ignition type of the explosive 3 and the explosive 3 is completely burned.

  In either process, the explosive 3 is not required to be dumped or to be connected to the detonator. Therefore, the explosive 3 can be completely burned safely and efficiently. .

  In the above-described embodiment, the disc 4, the container 14 and the powder 24 as the fire type are all made of the iron material (SS400). However, the present invention is not limited to this. , S35C (carbon steel material for mechanical structure) and SCM435 (chromium molybdenum steel material), and other fire type metals such as A5052 (Al-Mg alloy) which is an aluminum alloy material and C5191 which is a copper alloy material (Phosphor bronze) or carbon black powder can be used other than metal.

  Moreover, although the case where the explosive 3 was a TNT explosive was shown in the above-mentioned Example, it is not limited to this, The explosive disposal method concerning this invention is applied to the processing of a landmine or a non-explosive bomb. Of course it is also possible.
