Abstract

PURPOSE: A water tube blasting method is provided to increase the crushing amount per hole by increasing the friability index, a resistance line and a gap between holes to a good state, thereby improving the blasting efficiency and reduce the generation of dust. CONSTITUTION: A water tube blasting method comprises the following steps. Boring is performed in order to form a blasting hole. The waterproof vinyl is inserted inside the blasting hole. A priming explosive(120) is inserted inside the waterproof vinyl, connected to a detonator and successively installed with explosives on the upper part. The waterproof vinyl is injected with water inside and filled up with sand. The priming explosive is ignited to blast the targeted bedrock. The waterproof vinyl is pushed inside the blasting hole after being injected with water and collected perfectly with explosives, whereby an explosive chamber and a filled-up chamber is separated as well as the loss detonation pressure caused by the difference in diameter of a bored hole and the diameter of an explosive chamber is prevented.

본 발명은, 먼저 암반(R)에 발파공(100)을 형성하는 천공작업을 수행한다.The present invention, first performs a drilling operation to form a blast hole 100 in the rock (R).

그리고, 상기 발파공(100)의 내측으로 전폭약포(120)를 삽입할 수 있는 방수비닐(130)을 삽입한다.Then, insert the waterproof vinyl 130 to insert the full width drug 120 into the blasting hole 100.

계속하여, 상기 방수비닐(130)에 삽입된 전폭약포(120)에는 뇌관(125)이 연결되며, 상기 전폭약포(120)의 상부에 순차로 폭약(140)을 장약한다.Subsequently, the primer 125 is connected to the full width medicine 120 inserted into the waterproof vinyl 130, and the explosive charge 140 is sequentially charged on the top of the full width medicine 120.

그리고, 상기 방수비닐(130)의 내부에 물(W)을 공구까지 주입하여 전색재로 대체하거나 장약실 상부를 밀봉하여 전색(200) 작업을 수행한다.Then, water (W) is injected into the inside of the waterproof vinyl 130 to the tool to replace the color material or seal the upper chamber to perform the color 200 work.

더하여, 상기 전폭약포(120)를 기폭하여 발파공(100)에 폭발압력을 직접 전달하여 대상암반을 파쇄토록 한다.In addition, by detonating the full width drug 120 to direct the explosion pressure to the blasting hole 100 to fracture the target rock.

즉, 상기 발파대상 암반(R)에 장전되어 있는 전폭약포(120)의 기폭을 위해 뇌관(125)을 모두 연결하여 회로를 형성하고 발파기를 사용하여 기폭을 함으로써 암반을 파쇄하는 것이다.That is, for detonation of the full width drug 120 loaded in the blasting target rock R, all the primers 125 are connected to form a circuit, and the detonation is performed by using the blasting machine to detonate the rock.

한편, 상기 전폭약포(120) 및 각 폭약(140)은 물에 의해 포집되어 있어 천공경(발파공의 지름)과 장약경(폭약의 지름)의 차이에 의한 영향으로 폭굉 압이 소실됨을 막아준다.On the other hand, the full width drug 120 and each explosives 140 are collected by water to prevent the detonation pressure is lost due to the difference between the diameter of the hole (diameter of the blast hole) and the long diameter (diameter of the explosive).

또한, 상기 전색(200)공정은 공구까지 물을 채워 전색밀도를 높이거나 또는 장약실의 상부에 모래 등의 전색 시 방수비닐(180)을 밀어 넣어 장약부와 전색부를 구분시킨다.
In addition, the color 200 process is to fill the water up to the tool to increase the color density or push the waterproof vinyl 180 when the color of the sand or the like on the top of the chamber to distinguish between the charge part and the color part.

상기와 같은 구성으로 이루어진 본 발명의 동작을 도면을 통해 구체적으로 설명한다.The operation of the present invention having the above configuration will be described in detail with reference to the drawings.

도 2 내지 도 3에서 도시한 바와 같이 본 발명은, 먼저 파쇄를 원하는 암반(R)에 발파공(100)을 형성하는 천공작업을 수행한다.As shown in Figures 2 to 3, the present invention first performs a drilling operation to form a blast hole 100 in the rock (R) to be crushed.

그리고, 상기 발파공(100)의 내측으로 전폭약포(120)를 포함하는 방수비닐(130)을 삽입한다.Then, the waterproof vinyl 130 including the full width drug 120 into the blasting hole 100 is inserted.

이때, 상기 방수비닐(130)은 일정무게를 갖는 전폭약포(120)에 뇌관(125)을 연결시켜 방수비닐(130)에 먼저 삽입한 후 그 무게에 의해 발파공(100) 내에 삽입하며, 전폭약포(120)의 상부에 필요한 폭약(140)을 순차로 적층하여 장약한 후 방수비닐(130)의 내측에 물(W)을 공구까지 주입 또는 장약실 상부를 방수비닐(130)로 이격시켜 전색(200) 작업을 수행한다.At this time, the waterproof vinyl 130 is connected to the primer 125 to the full width drug 120 having a certain weight and inserted into the waterproof vinyl 130 first, and then inserted into the blast hole 100 by its weight, full width drug The explosives 140 required on the upper part of the 120 are sequentially stacked to be charged, and then water (W) is injected into the tool to the inside of the waterproof vinyl 130, or the upper part of the chamber is separated by the waterproof vinyl 130. 200) Perform the work.

그리고, 상기 전색작업이 완료되면 전폭약포(120)를 기폭하여 발파공(100)에 폭발압력을 전달하여 암반을 파쇄토록 한다. 이때 파쇄된 암반은 전방으로 이동하게 된다.
Then, when the coloration operation is completed, the full width drug 120 is triggered to transmit the explosion pressure to the blasting hole 100 so as to fracture the rock. The crushed rock will then move forward.

이와 같이 본 발명은 천공경에 비하여 장약경이 작아질수록 발파효과는 감소하므로 워터를 이용하여 밀 장전효과를 극대화시킬 수 있음은 물론 워터로 인하여 분진발생을 억제할 수 있는 공법인 것이다. As described above, the present invention reduces the blasting effect as the length of the medicine is smaller than that of the perforation diameter, so that the effect of maximizing the wheat loading by using water is of course a method that can suppress dust generation due to water.
