The present invention relates to a non-electric primer detonator and method used in the operation of the explosives, including a blasting operation, and more particularly to a detonation technology that can detonate non-electric primers safely and economically using an electric blasting machine.

Blasting works are carried out using industrial gunpowder when excavating rock in underground spaces such as tunnels or reservoirs, foundation rock excavations of civil engineering structures, quarries and mines. In order to prevent safety accidents, industrial gunpowder is so insensitive that it is manufactured so as not to detonate on its own. That is, in order to detonate the industrial powder, the primer is detonated from the ignition device (blaster), and then the industrial powder is exploded and detonated to destroy the rock.

As described above, as a technique for detonating explosives, a fuse blast, an electric primer blast, and a non-electric primer blast method are used. In the prior art, the method of blasting the conductive wire is a method of igniting a primer by a spark using a ignition device called a black stone coated conductive wire, which is not currently used as a safety problem. This is because as the explosion blasting accidents increase, stability of safety primers is required to be increased, and it is because of the industry's goal to increase productivity by blasting at the time of precise blasting and delaying blasting.

On the other hand, the electric blasting method is a method in which the ignition jade is ignited by the heat generated from the platinum wire installed in the primer by electric energy using an ignition device called an electric blasting device. Because of the risk of explosion in the explosive control law, the application is gradually reduced in blasting constructions involving electrical hazards such as tunnels, underground spaces, and large blastings, and is classified into MS electric primer and LP electric primer. .

Non-electric blasting method is a combination of a primer on a shock tube coated with HMX + Al 0.02g / m in an outer diameter 3mm, 1.5mm inner diameter polyethylene (PE) round tube, using an ignition device called a non-electric blasting machine 700 Ignition by high pressure spark.

1 is a configuration diagram showing a non-electric blasting method according to the prior art. The non-electric blasting method shown in Figure 1 is an increasing trend in the electrical blasting construction and open-air co-operation primer, open-air connection primer, tunnel connection primer, MS (ms initial primer), LP (LP initial primer) , Starter (shock tube detonator primer) and the like.

By the way, the blasting works use the gunpowder to crush the rock, which causes blasting pollution such as tombstones, vibrations, and storm pressures, and the Explosives Control Regulations force the ignition place to be placed at least a distance from the blasting place. .

Therefore, when attempting to apply the non-electric blasting method in the blasting construction, there is an inconvenience to apply a starter (starter) of a predetermined length or more. Moreover, the shock tube of the extended starter is disposable and the tube residue remains after blasting, which is inconvenient to collect the tube residues in large quantities, resulting in an increase in construction cost economically. In order to solve the above problems, a blasting method using a non-electric primer and an electric primer may be used.

2 is a view showing a blasting method using a non-electric primer and an electric primer in accordance with the prior art. Referring to FIG. 2, a non-electric primer 100 is used for each blasting hole 400 when the explosives are loaded or a bench blast, and the final connection is made using an electrical primer 20 to connect the non-electric primer and the electric. Perform blasting with mixed primer.

However, the prior art shown in FIG. 2 is no different from the electrical primer blasting method in the blasting construction with electrical hazards, and there still remains a problem that can be misunderstood by leakage current and static electricity.

The first object of the present invention is to apply a method for detonating a shock tube of a non-electric primer that is applied to a non-electric blasting method. To provide a method and apparatus for detonating a shock tube of a primer.

The second object of the present invention is, in addition to the first object, due to the economic burden that occurs when the shock tube of the shock tube starter applied to the non-electric blasting method is used for a single use and the tube residue after the disposable blasting. The present invention provides a method and apparatus for detonating a shock tube of a non-electric primer that solves an environmental pollution problem.

In order to achieve the above object, the present invention discloses a technique for detonating the shock tube of the non-electric primer with a conventional electric blaster without further using the non-electric blasting machine (700). In other words, the present invention is composed of a device for generating a high-pressure spark to detonate a non-electric primer without a starter (shock tube detonator).

Hereinafter, with reference to the accompanying drawings Figures 3 to 4 will be described in detail the detonator and method of the non-electric primer according to the present invention.

Figure 3 is a block diagram illustrating a method of detonation of a non-electric primer according to the present invention. Referring to FIG. 3, a spark ignition device 200 and a connection line 300 are illustrated in the non-electric primer 100. In addition, the conventional electric blasting machine 600 and the blasting bus 500 is shown.

The spark ignition device 200 is a spark generator that generates ultra high pressure into a spark. That is, the spark ignition device is a device that converts the voltage applied by the electric blasting device 600 into a spark of a high pressure.

4 is a view showing an embodiment of a spark ignition device constituting a non-electric primer detonator according to the present invention. Referring to Figure 4, the spark ignition device 200 according to the present invention is a device for generating a high-pressure spark in response to a high voltage of 300V ~ 1450V and detonates the shock tube of the non-electric primer. The flame primer is composed of a rubber packing cover 110 for connection and waterproofing of the positive and negative terminals 11 and the discharge tip 12 and the non-electric primer 60 connected to the blasting machine.

The spark ignition apparatus 200 according to the present invention generates a high-pressure spark while the insulation state of the insulator is broken under a high voltage, but the spark is not caused by a continuous discharge, but an intermittent discharge occurs in a short time, so that the shock of the non-electric primer It can detonate the tube. On the other hand, the rubber packing cover 110 of the flame generating device 200 is easily wrapped after combining with a water-resistant material for waterproofing the coupling portion of the shock tube.

The foregoing has outlined rather broadly the features and technical advantages of the present invention to better understand the claims of the invention which will be described later. Additional features and advantages that make up the claims of the present invention will be described below. It should be appreciated by those skilled in the art that the conception and specific embodiments of the invention disclosed can be readily used as a basis for designing or modifying other structures for carrying out similar purposes to the invention.

In addition, such modifications or altered equivalent structures by those skilled in the art may be variously changed, substituted, and changed without departing from the spirit or scope of the invention described in the claims.

As described above, the present invention detonates the non-electric primer by using a spark ignition device, it is possible to reduce the amount of use of the shock tube blasting (about 200m) of the non-electric primer for the first ignition from the environmental point of view compared to the prior art As a result, there is an advantage that can reduce the construction cost. In addition, the shock tube of the non-electric primer can be detonated without using an electrical primer, thereby preventing a safety accident due to leakage current, endnote current, or static electricity, which may be present at a construction site during blasting.

In other words, it does not detonate the shock tube by using an electric primer and does not use a non-electric blasting machine 700 and a starter, and enables the non-electric blasting in terms of environmental, economic and safety aspects. Excellent effect can be obtained.
