本発明は低振動、低騒音ＡＮ−ＦＯ爆薬を製造する方法
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing low vibration, low noise AN-FO explosives.
ＡＮ −ＦＯ爆薬で岩石等を破砕する場合、被破砕部近
傍は勿論のこと、可成りの広範囲に亘り振動、騒音が発
生する。When crushing rocks etc. with AN-FO explosives, vibrations and noise are generated not only in the vicinity of the crushed part but also over a considerable wide area.
この現象を低減するため、本発明者らはΔＮ−ＦＯ爆薬
に青粉を混合することで、低振動、低騒音で破砕できる
という目的を達成し本発明を完成するに至った。すなわ
ちＡＮ−ＦＯ爆薬に青粉を混合することにより、爆薬の
装填密度を下げ爆速を低下させ、低振動低騒音爆薬とす
ることを特徴とするＡ Ｎ−ＦＯ爆薬の製造方法である
。In order to reduce this phenomenon, the inventors of the present invention mixed blue powder into the ΔN-FO explosive, thereby achieving the objective of crushing with low vibration and low noise, and completed the present invention. That is, this is a method for producing an AN-FO explosive characterized by mixing blue powder with the AN-FO explosive to lower the loading density of the explosive and lower the detonation velocity, resulting in a low-vibration, low-noise explosive.
本発明で混合する物質としては青粉や砂又は１、パーラ
イト等の発泡物などのいずれでもよい。The substance to be mixed in the present invention may be blue powder, sand, or foamed materials such as 1 and perlite.
例えば石灰石の粉や砕砂は容易に人手できるに、混合時
に静電気が発生せず安全に混合できる。For example, limestone powder and crushed sand can be easily mixed by hand, and can be safely mixed without generating static electricity.
混合する物質の粒度には特に制限はないが、ＡＮ−ＦＯ
爆薬と同程度のものが均一に混合でき装填もしやすい。There are no particular restrictions on the particle size of the substances to be mixed, but AN-FO
It can evenly mix the same amount of explosives and is easy to load.
混合物の混入量は多い程振動騒音の低下の効果はあるが
、逆にＡＮ−ＦＯ爆薬の量が相対的に減少するため破砕
の目的が達成されなくなるので、混合する割合は５０％
体積％以下である。The larger the amount of the mixture mixed in, the more effective it is in reducing vibration and noise, but on the other hand, the amount of AN-FO explosive will be relatively reduced, making it impossible to achieve the purpose of crushing, so the mixing ratio should be 50%.
volume% or less.
本発明によるＡＮ−ＦＯ爆薬を用いれば、発破時の振動
騒音の公害を低減することができる。By using the AN-FO explosive according to the present invention, it is possible to reduce vibration and noise pollution during blasting.
次に本発明によるＡＮ−ＦＯ爆薬を用いた実験例で具体
的に説明する。Next, an experimental example using the AN-FO explosive according to the present invention will be specifically explained.
実験例
本実験での孔径は直径１ Ｆｌ ５ ｍｍ、孔長７ｍ、
抵抗線２．５ｍ、孔間隔２．５ｍで、ＭＳ電気雷管を使
用し雷管にはカーリット爆薬５０ ｇを利け、ブースフ
とした。測定結果は表−１に示すとおりである。Experimental example The hole diameter in this experiment was 1 Fl 5 mm in diameter, 7 m in length,
A MS electric detonator was used with a resistance wire of 2.5 m and hole spacing of 2.5 m, and the detonator was charged with 50 g of Carlit explosive to serve as a booth. The measurement results are shown in Table-1.
表 −１
表−１に示すとおり混合割合を増加すると振動及び騒音
が低下し、周囲に及ぼす影響が減少した。Table 1 As shown in Table 1, increasing the mixing ratio reduced vibration and noise, reducing the impact on the surroundings.
