【発明の詳細な説明】
本発明は岩石、地山、コンクリ−１・等の脆性物体をＡ
Ｎ−ＦＯ爆薬で破砕する方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention enables brittle objects such as rocks, earth, concrete, etc.
This invention relates to a method of crushing with N-FO explosives.
ＡＮ−ＦＯ爆薬で岩石等を破砕する場合、被破砕部は勿
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 or the like with AN-FO explosives, vibrations and noise are generated not only in the crushed area but also over a fairly wide area.
この現象を低減するため、本発明者らはＡＮ−ＦＯ爆薬
に岩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。In order to reduce this phenomenon, the present inventors mixed rock powder with AN-FO explosives, thereby achieving the objective of crushing with low vibration and low noise, and completed the present invention.
すなわち、ＡＮ−ＦＯ爆薬に岩粉を混入することにより
、爆薬の装填密度を下げ爆速を低下させ低振動低騒音で
破砕することを特徴とする破砕方法である。That is, this is a crushing method characterized by mixing rock powder into AN-FO explosives to lower the loading density of the explosives, lowering the detonation speed, and crushing them with low vibration and low noise.
本発明で混合する物質としては岩粉や砂又はパーライト
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 rock powder, sand, or foamed materials such as pearlite.
例えば石灰石の採掘場ではせん孔時に発生するくり粉を
使用すれば、手近に入手できる上、静電気が発生せず安
全に混合できる。For example, in limestone quarries, if you use the turning powder generated during drilling, you can easily obtain it, and it can be mixed safely 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しやすい。There are no particular restrictions on the particle size of the substances to be mixed, but AN-FO
It can be mixed evenly with 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% by volume or less. be.
本発明の方法を用いればＡＮ−ＦＯ爆薬による発破時の
振動、騒音の公害を低減することができる。By using the method of the present invention, it is possible to reduce vibration and noise pollution during blasting of AN-FO explosives.
次に実験例をあげて本発明を具体的に説明する。Next, the present invention will be specifically explained by giving experimental examples.
実験例
本実験での孔径は直径１０５ 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；・爆薬５０ｇ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 105 mm in diameter, 7 m in length, resistance wire 2.5 m, and hole spacing 2.5 m. An MS electric detonator was used, and 50 g of explosive was charged in the detonator to make it 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.
