The present invention relates to a gunpowder to add a display means to the packaging material to use an appropriate amount of gunpowder, and in particular, a display means for enabling a quantitative subdivision in a packaging material for packaging a blasting gun powder used in the industry. In addition, it relates to a gunpowder that can be used to load as much gunpowder in the blast hole by quantitatively cutting the gunpowder in the field during the blasting work.

In general, the explosives (explosives) are transported or traded in a gimbap shape or a sausage shape by packing a decomposable substance into a gimbap or sausage form with a film or paper made of paper (oil paper) or a synthetic resin material. The explosives are loaded into balls such as blasting balls and then exploded and used for mining or civil works.

The gimbap or sausage-type gunpowder is made as a packing standard having various lengths and diameters so that an appropriate amount can be used. As an example, a weight of 125g, 250g, 500g, 800g, 1000g, or 2500g is used to change the diameter and length (diameter: 25mm length: 250mm; diameter: 32mm length: 295mm; etc.). Because gunpowder can control the degree of blasting by weight, the diameter and length can be changed according to the weight of gunpowder and the size of the blasting hole.

In addition, the industrial blasting explosives can be classified into dynamite, emulsion explosives, or anesthetic explosives, and the explosive substance is composed of a gel type, an emulsion type, or a slurry type, and the material is packaged and aired. Or to prevent contact with moisture, to facilitate management and to facilitate transport or loading.

The actual picture of the conventional general gunpowder made as described above is shown in Figure 1, Figure 1a is a photograph showing a part of the conventional gimbap-type gunpowder, Figure 1b is a photograph showing a conventional sausage-type gunpowder, Figure 2 A partially cutaway perspective view of a conventional gimbap type explosives.

As shown in the drawing, there is an explosive substance 20 inside the gunpowder 10. The explosive substance 20 is individually packaged in the form of gimbap as an oil paper 30, and an oil paper which is a packaging material ( 30, the trade name, manufacturer or specification is printed.

Method of blasting using the conventional industrial gunpowder as described above first drilled a hole (blasting hole) with a diameter (32 ~ 75mm) enough to enter the gunpowder 10 packed as described above in the rock using a perforator (puncture work) In this blasting hole, the amount of gunpowder (10) according to the purpose is used (loaded) as necessary (loading), followed by filling up the remaining space of the blasting hole with a color-like material such as sand to explode.

At this time, the gunpowder management engineer will design the amount of gunpowder according to the type of rock, the degree of crushing and the kind of explosive material, and the amount of gunpowder determined by the gunpowder manager by the technicians in the field (including gunpowder management engineer). It is loaded to the blast hole to perform the blasting work. In other words, it is designed to use a certain number of gunpowder of a specific company packed to a certain standard, and in the field, the blasting work by loading the number of gunpowder that is designed according to the specification among the gunpowder of the specific company according to the design.

The important thing in the above blasting work is to load the right amount of gunpowder into the ground or rock to be broken so that the ground or rock can be crushed to the desired level. If the amount of gunpowder is insufficient, the rock will not be destroyed due to the emptying phenomenon. Violence of gunpowder may rupture out of the blast hole and cause harm to people or buildings around the blast hole.If the amount of gunpowder is excessive, it is used to break the rock and cause unnecessary vibration or fracture by the explosive force of the remaining gunpowder. Rock is scattered around the blast hole. This risks unnecessary impacts on nearby buildings or structures, causing them to collapse, weaken seismic forces, and increase fatigue, as well as serious hazards that can cause personal injury.

The reason why the amount of gunpowder is insufficient or excessive is that the amount of gunpowder loaded is not only designed by the number of gunpowder packed individually, but the gunpowder packed to a certain standard such as 1/2, 1/3 or 1/5. In case of not loading the gunpowder correctly, the shortage of gunpowder occurs. If an overload of the gunpowder is loaded in this way, there is a problem that co-occurrence as described above or overexplosion occurs.

Therefore, in order to load the correct amount of gunpowder, there is a hassle that the gunpowder management engineer has to measure with a ruler in the field and cut the gunpowder.

On the other hand, since blasting work is often performed in urban areas, fine control blasting is required to safely blast without affecting the surrounding ground, structure, or building, so it is necessary to load the correct amount of gunpowder. It is increasing.

In order to solve the problems of the prior art as described above, the present invention provides a technical problem to add a display means to the packaging material surrounding the explosive material so that the powder can be quantitatively cut and used.

The present invention is an explosive substance consisting of nitroglycerin or ammonium nitrate;

Wrapping materials such as oil paper, synthetic resin film or synthetic resin pipe to form a certain shape while wrapping the above detonable material; And

The display means added to the surface of the packaging material; can be configured to realize the above technical problem.

In the accompanying drawings, like reference numerals refer to like elements.

Referring to Figure 3, the gunpowder 100 having a packaging material is added to the display means for use in the appropriate amount of the present invention consists of a long columnar shape, such as gimbap or sausage shape, this gunpowder 100 is made of nitroglycerin as a raw material Wrapping is made up of an explosive material (200) and the wrapping material (300) made of oil paper to limit the contact with the outside air and moisture by surrounding the explosive material (200) and to increase the ease of movement and handling, this packaging material (300 In the longitudinal direction of the outer circumferential surface of the one side is printed a ruler 410 in centimeters (cm), the ruler in inches (inch) on the opposite side of the centimeter unit ruler 410 printed on the outer peripheral surface of the packaging material 300 412 is printed so that the gun powder can be cut and used in length units. These gunpowder can be loaded by cutting gunpowder with a certain size (eg 32mm gun powder from a specific company) in centimeters (eg 5 cm) or inches.

Figure 4 is an embodiment using a line as an equal mark formed on the outer peripheral surface of the packaging material, 1/2 (Fig. 4a), 1/3 (Fig. 4b), 1/4 at intervals of 90 degrees in four directions in the circumferential direction It is made by printing a short line along the circumference at regular intervals in the longitudinal direction so as to be subdivided by (Fig. 4C) and 1/5 (Fig. 4D). The present embodiment is a line that is equalized to the wrapping material 300 made of the expandable material 200 and the oil paper surrounding the expandable material 200 and the narrow strip 420 formed in the longitudinal direction on the outer circumferential surface of the wrapping material. 422 is formed.

According to the present embodiment, one gunpowder 100 can be cut quantitatively into 2, 3, 4 or 5 portions. That is, in the case of dividing into two, the gunpowder 100 may be rotated in the direction in which the bisected mark is printed as shown in FIG. 4A, and the subdivision may be divided in half on the basis of the line 422 which is an equal mark. When only one third of the gunpowder is to be used, the gun powder may be cut based on one line 424 by turning the gunpowder 100 in the direction in which the third quarter mark is printed as shown in FIG. If only 4/4 is to be used, the gun powder may be cut based on one line 426 by turning the gunpowder 100 in the direction in which the quarter mark is divided into four as shown in FIG. 4C, and one fifth of the gunpowder 100 is used. If you want to use only, as shown in Fig. 4d by turning the gunpowder 100 in the direction in which the five-quarter mark is printed, it may be used by cutting on the basis of one line 428. This prevents the overload of gunpowder that is loaded.

5 and 6 are equal marks formed on the outer circumferential surface of the packaging material and are formed by printing the star shapes 430 and 432 or the diamond shapes 440 and 442 in units to be divided into equal parts. Is the same as

In addition, Figure 7 is to use the connected elliptical shape (450, 452) as an equal mark, and to print the elliptical shape (450, 452) of the unit to be divided into, as a reference of the portion where the oval bone (454, 456) is cut off It is a unit. The operation of this embodiment is also the same as the embodiment shown in FIG.

On the other hand, Figure 8 is a circular shape (460, 462, 464) that is a simple shape as the most preferred embodiment of the present invention as an equal mark, it is divided into three parts (Fig. 8a), four parts (Fig. 8b) and five parts (Fig. 8c) is divided into equal parts so that the powder can be efficiently divided. According to the present embodiment, the gunpowder can be cut in almost all possible parts.

For example, if you want to use a half-divided gunpowder (1/2), turn the gunpowder 100 in the direction (Fig. 8b) marked with a quarter, and then reference the circular shape 463 with a second divided mark. When the gunpowder 100 is cut into two parts, the gunpowder 100 is turned in the direction (Fig. 8a) marked in three parts when the gun powder (1/6) is to be used. After cutting the gunpowder 100 with the circular point 460 with the first equalization mark and the middle point 461 of the start of the gunpowder 100 as a reference point, it is possible to use the gunpowder (1/6) that is accurately divided into six. Although it is not marked equally, the exact equalization is possible because the length of the gunpowder 100 is not so long, so that the first circular shape 460 and the middle part 461 of the beginning of the gunpowder can be easily found and divided in half. Because.

In the above, an embodiment of the present invention has been described. However, the present invention will be sufficient as long as it is a label capable of dividing the gunpowder even when using any shape as an equal mark. Many more changes will be possible. Therefore, the present invention is not limited only to the above-described embodiments, but those skilled in the art will be able to carry out the modifications and variations within the scope without departing from the spirit of the technical idea of the present invention, and such modifications or changes may be implemented by the following inventions.
