Description
본 발명은 친환경 탄광굴진용 에멀젼 폭약 조성물에 관한 것이다. The present invention relates to an eco-friendly emulsion explosive composition for coal mine excavation.
탄광굴진작업은 지하에 매장된 석탄을 캐기 위하여 탄맥까지의 갱도를 뚫는 과정이다. 석탄이나타나면 굴진작업이 끝나고, 채탄 작업을 시작한다. 탄광굴진용 폭약은 굴진작업시 발파할 때 갱내 존재하는 메탄가스 또는 탄가루가 폭발을 일으킬 수 있는 위험성이 없어야 하며, 석탄이 나타나기 전까지 갱도를 효율적으로 뚫기 위한 위력이 요구된다. Coal mine excavation is the process of drilling a tunnel to the coal mine to extract coal buried underground. Once coal appears, the excavation work ends and coal mining begins. Explosives for coal mine excavation must not have the risk of causing an explosion due to methane gas or coal powder present in the mine when blasted during excavation work, and are required to have enough power to efficiently penetrate the mine until the coal appears.
종래 탄광굴진용 폭약으로는 젤라틴 다이너마이트가 대표적으로 사용되고 있다. 그러나, 젤라틴 다이너마이트의 경우 제조 및 취급시의 위험성과 높은 원재료에 따른 경제성의 문제로 사용이 줄어들고 있는 추세이다. 젤라틴 다이너마이트의 대체품으로 대한민국 등록특허 제10-1995-0009193호에 출원된 '질산암모늄 다이너마이트 폭약 조성물'이 개발되었으나, 탄광굴진용으로 쓰기에는 적합하지 않다. '질산암모늄 다이너마이트 폭약 조성물'로 개발된 폭약의 경우, 위력을 증가시키기 위하여 알루미늄 분말과 같은 금속분말이 포함되어 있는데, 이는 메탄가스가 있는 탄광환경에서 폭발을 일으킬 수 있다. 또한 알루미늄 분말 사용시, 산소평형을 맞추기 위해 과염소산나트륨(NaClO4)를 첨가한다. 그러나 과염소산염은 갑상선 호르몬 시스템의 정상적 기능을 방해한다는 연구가 있으며, 임산부가 음용시 태아의 발달에 손상을 줄 수 있다는 연구결과가 있어 지속적인 사용 가능 여부가 불투명하다. 따라서 과염소산염이 포함되어 있지 않아 친환경적이면서도 굴진작업시 적절한 위력을 제공할 수 있는 폭약 조성물의 개발이 요구된다. Gelatin dynamite is typically used as an explosive for coal mine excavation. However, in the case of gelatin dynamite, the use of gelatin dynamite is decreasing due to economic issues due to the risk of manufacturing and handling and the high raw materials. 'Ammonium nitrate dynamite explosive composition', applied for Korean Patent No. 10-1995-0009193, has been developed as a replacement for gelatin dynamite, but it is not suitable for use in coal mine excavation. In the case of explosives developed as 'ammonium nitrate dynamite explosive composition', metal powders such as aluminum powder are included to increase power, which can cause an explosion in a coal mine environment with methane gas. Additionally, when using aluminum powder, sodium perchlorate (NaClO 4 ) is added to balance oxygen. However, studies have shown that perchlorate interferes with the normal function of the thyroid hormone system, and studies have shown that drinking it by pregnant women can damage the development of the fetus, so it is unclear whether it can be used continuously. Therefore, there is a need to develop an explosive composition that does not contain perchlorate, is environmentally friendly, and can provide appropriate power during excavation work.

The purpose is to provide an explosive composition for coal mine excavation that is inexpensive, safe for the human body, environmentally friendly, safe for use in coal mines with a lot of work, and has significantly improved convenience and long-term storage compared to existing explosive compositions.
본 발명은 88~98 중량%의 산화제 수용액, 0.1~6 중량%의 유화제, 및 0.1~6 중량%의 연료유를 포함하는 폭약용 에멀젼; 및 상기 폭약용 에멀젼 100 중량부를 기준으로 10 내지 30 중량부의 PPAN(프릴초안);을 포함하는 탄광굴진용 에멀젼 폭약 조성물을 제공한다.The present invention provides an emulsion for explosives containing 88 to 98% by weight of an aqueous oxidizing agent solution, 0.1 to 6% by weight of an emulsifier, and 0.1 to 6% by weight of fuel oil; and 10 to 30 parts by weight of PPAN (pril draft) based on 100 parts by weight of the emulsion for the explosive.

이하에서 본 발명을 자세하게 설명한다. The present invention will be described in detail below.
본 발명의 탄광굴진용 폭약 조성물은 88~98 중량%의 산화제 수용액, 0.1~6 중량%의 유화제, 및 0.1~6 중량%의 연료유를 포함하는 폭약용 에멀젼; 및 상기 폭약용 에멀젼 100 중량부를 기준으로 10 내지 30 중량부의 PPAN(프릴초안);을 포함하는 것을 특징으로 한다.The explosive composition for coal mine excavation of the present invention includes an emulsion for explosives containing 88 to 98% by weight of an oxidizing agent aqueous solution, 0.1 to 6% by weight of an emulsifier, and 0.1 to 6% by weight of fuel oil; And 10 to 30 parts by weight of PPAN (pril draft) based on 100 parts by weight of the emulsion for explosives.
본 발명의 폭약용 에멀젼은 88~98 중량%의 산화제 수용액을 포함한다. 상기 산화제 수용액의 조성비가 상기 범위를 벗어나면 에멀젼이 형성되지 않을 수 있으며, 양이 적을 경우에는 불폭되는 문제가 발생할 수 있다.The emulsion for explosives of the present invention contains 88 to 98% by weight of an aqueous oxidizing agent solution. If the composition ratio of the oxidizing agent aqueous solution is outside the above range, an emulsion may not be formed, and if the amount is small, a problem of detonation may occur.
본 발명의 일 실시형태에 있어서, 상기 산화제 수용액은 질산암모늄 60 내지 80 중량%, 질산나트륨 및 질산칼슘 중에서 선택되는 1종 이상 2 내지 10 중량%, 모노메틸 아민 나이트레이트(MMAN) 및 에틸렌 디아민 디나이트레이트(EDDN) 중에서 선택되는 1종 이상 1 내지 10중량%, 및 물 1 내지 20 중량%을 포함할 수 있다.In one embodiment of the present invention, the aqueous oxidizing agent solution contains 60 to 80% by weight of ammonium nitrate, 2 to 10% by weight of at least one selected from sodium nitrate and calcium nitrate, monomethyl amine nitrate (MMAN), and ethylene diamine diamine. It may include 1 to 10% by weight of one or more types of nitrate (EDDN) selected from the group consisting of nitrate (EDDN), and 1 to 20% by weight of water.
상기 산화제 수용액은 화학적 예감제인 모노메틸 아민 나이트레이트(MMAN) 및/또는 에틸렌 디아민 디나이트레이트(EDDN)을 상기 함량으로 포함함으로써 기존의 탄광용 폭약에 비하여 위력을 강화시켜 굴진작업시 적합한 에너지를 제공한다.The oxidizing agent aqueous solution contains the chemical oxidizers monomethyl amine nitrate (MMAN) and/or ethylene diamine dinitrate (EDDN) in the above content, thereby enhancing the power compared to existing coal mine explosives and providing suitable energy during excavation work. do.
본 발명의 폭약용 에멀젼은 0.1~6 중량%의 유화제를 포함한다. 상기 유화제의 조성비가 상기 범위를 벗어나면 에멀젼이 형성되지 않거나 불폭되는 문제가 발생할 수 있다. The emulsion for explosives of the present invention contains 0.1 to 6% by weight of an emulsifier. If the composition ratio of the emulsifier is outside the above range, the emulsion may not be formed or may not explode.
본 발명의 일 실시형태에 있어서, 상기 유화제로는 SMO(Sorbitan monoleate) 및 PIBSA 아민염(Amine salt of polyisobutylenesuccinicanhydride) 등으로 이루어진 군으로부터 선택되는 1종 이상이 사용될 수 있으나, 상기 성분으로 제한되는 것은 아니다. In one embodiment of the present invention, the emulsifier may be one or more selected from the group consisting of SMO (Sorbitan monoleate) and PIBSA amine salt of polyisobutylenesuccinicanhydride, etc., but is not limited to the above components. .
본 발명의 폭약용 에멀젼은 0.1~6 중량%의 연료유를 포함한다. 상기 연료유의 조성비가 상기 범위를 벗어나면 에멀젼이 형성되지 않거나, 불폭되는 문제가 발생할 수 있다.The emulsion for explosives of the present invention contains 0.1 to 6% by weight of fuel oil. If the composition ratio of the fuel oil is outside the above range, problems such as emulsion not being formed or detonation may occur.
본 발명의 일 실시형태에 있어서, 상기 연료유는 고체성분인 왁스와 액체성분인 오일을 10:1 내지 20:1의 중량비로 포함할 수 있다. In one embodiment of the present invention, the fuel oil may include wax, which is a solid component, and oil, which is a liquid component, at a weight ratio of 10:1 to 20:1.
수공이 많은 탄광내에서 폭약의 약상이 너무 무르면 천공 작업시 꺽이거나, 접혀서 사용상의 어려움이 발생할 수 있으며, 너무 딱딱하면 뇌관삽입이 어렵고, 제조후 장기저장성(에멀젼 폭약은 유통기한을 감안하여 최소 1년의 장기저장안정성이 유지되어야 한다)이 저하될 수 있는 문제가 발생한다. 그러므로, 왁스와 액체성분인 오일은 10:1 내지 20:1의 중량비, 바람직하게는 13:1 내지 20:1, 더욱 바람직하게는 15:1 내지 20:1로 포함될 수 있다. 왁스와 액체성분인 오일의 중량비가 상기 범위를 벗어나는 경우, 상기와 같은 문제가 발생하여 사용상 편의성을 개선하기 어려우며, 충분한 저장안정성을 확보하기 어렵다.In coal mines where manual work is required, if the base of the explosive is too soft, it may bend or fold during drilling work, causing difficulty in use; if it is too hard, it may be difficult to insert the detonator, and long-term storage after manufacture (emulsion explosives have a minimum shelf life considering the expiration date) A problem may arise where the long-term storage stability of one year must be maintained. Therefore, wax and oil, which is a liquid component, may be included in a weight ratio of 10:1 to 20:1, preferably 13:1 to 20:1, and more preferably 15:1 to 20:1. If the weight ratio of wax and oil, which is a liquid component, is outside the above range, the above problems occur, making it difficult to improve convenience in use and ensuring sufficient storage stability.
유중수적형의 폭약의 경우 외부로 노출된 연속상의 성분인 연료유의 조성이 사용성과 장기저장성에 영향을 미친다. 연료유를 구성하는 성분인 상온에서 고체로 존재하는 왁스와 액체로 존재하는 오일이 상술한 범위와 같이 적절한 비율로 구성되어야 이러한 사용상의 편리성과 높은 장기저장성을 제공할 수 있다. In the case of water-in-oil explosives, the composition of fuel oil, which is a component of the continuous phase exposed to the outside, affects usability and long-term storage. The components that make up fuel oil, wax that exists as a solid at room temperature and oil that exists as a liquid, must be composed in an appropriate ratio within the above-mentioned range to provide such convenience of use and high long-term storage.
