Abstract

PURPOSE: To effectively boost by detonating a detonator dynamite by charging cartridge increment (stick) in an explosive charge hole opened at a baserock, then charging the increment having detonator dynamite, and charging a filler and the increment to be used to perform an open blasting construction. CONSTITUTION: A cylinder 14 made of cardboard is pressed from one end of a cylindrical increment 11 made of a film formed of three layer structure of polyethylene and nylon, and ammonium sulfate oil material detonating explosive 15 is charged. At the time of blasting, the detonator dynamite is charged in the cylinder 14, and then charged in the explosive charge hole.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medicine package bag used in a blasting operation of a light and a manufacturing method thereof.

[0002]

2. Description of the Related Art Usually, when performing a light blasting work, as shown in FIG.
After piercing each of them, each charging hole 1 is successively loaded with a sachet bag (increase die) 2 filled with an ammonium nitrate oil explosive called AN-FO. After loading the parent die (hereinafter referred to as the parent die) 3 of the above, the filling hole such as clay or sand 4 is closed, and then,
It was detonated by the detonation of the parent die in each charging hole, and the rock was destroyed.

[0003]

When loading the parent die, it is necessary to surely bring the parent die into contact with the medicine bag. If the parent die is supported by the inner wall of the charging hole at the time of loading, or if it is loaded in the state that it cannot reach the medicine bag due to the presence of pebbles or earth and sand between the parent die and Wrapping bag (added die)
It will not be transmitted to and will not be able to do the intended blast. In addition, if the medicine bag (additional die) is buried unexploded, there is a risk that the bit will hit the non-fired medicine packaging bag (additional die) and explode when excavating with a rock drill.

An object of the present invention is to solve the above problems and to provide a medicine package bag which can be surely transmitted by the initiation of a mother die, and a manufacturing method thereof.

[0005]

The medicine packaging bag of the present invention comprises a cylindrical bag having a parent die loading hole at one end, and an ammonium nitrate oil explosive loaded in the bag. According to the present invention, the parent die is loaded in the loading hole of the bedrock while being loaded in the loading hole of the medicine package bag, and the parent die is loaded in the drug package bag. The explosion is surely transmitted to the medicine bag.

After loading, the parent die must be adhered with an adhesive or the medicine bag must be bound and fixed near the entrance of the loading hole so as not to fall off from the loading hole of the medicine bag. Although the above-mentioned medicine bag can be integrally formed of resin, it is preferably composed of a tubular film made of a laminate of polyethylene and nylon, like the conventional medicine bag.
Then, from the heat-sealed side at one end, a paper or resin hard cylinder having the same length as the parent die is pressed and formed. In this case, the tubular film is preferably provided with a tubular portion on one side thereof so that the tubular portion can be inserted therein by heat sealing, and the tubular portion is inserted so as to push the tubular portion.

[0007]

[Example] One end of a tubular bag 11 made of a film having a three-layer structure of polyethylene and nylon, and a width enough to heat-seal in parallel from one end to a length corresponding to a parent die, and a tube to be described later enters. Linear fused portions 12, 1 having
3 (FIG. 2).

Next, the cylinder 14 (FIG. 3) made of thick paper is pushed into the fusion-bonding portion 13 through the fusion-bonding portion 12, and then the ammonium nitrate oil explosive 15 is charged through the opening at the other end of the bag. And tube 1
Fill explosive 15 up to around 4. Next, the opening end of the bag 11 is squeezed and closed, and the bag 11 is bound with an aluminum ring 16 to form a medicine bag 17 (FIG. 4).

When using the medicine package bag 17 constructed as described above, the parent die is loaded in the cylinder 14, and the vicinity of the inlet is tied and fixed with a string. Then, as shown in FIG.
After loading the usual medicine packing bag (increase die) 2 into the charging hole 1, the above-mentioned medicine packing bag 17 containing the parent die 3 is loaded at the end, and the stuffing 4 is put in to perform blasting.

[0010]

The present invention is constructed as described above and has the following effects. According to the medicine packing bag according to claim 1, since the parent die is loaded into the charging hole while being loaded, when the parent die is detonated, it is surely transmitted to the medicine packing bag (increase die).
The blasting work can be carried out reliably, and the danger at the time of subsequent work due to non-explosion can be eliminated.

According to the manufacturing method of the second aspect, the bag of the conventional medicine bag can be used as it is, only by using the hard cylinder made of paper or resin, and the medicine bag can be made inexpensive. It can be manufactured.
