Description

本発明は、砕石、採掘、トンネル掘削などの産業発破に用いられるバルク含水爆薬またはその中間体用排出装置に関するものである。   The present invention relates to a bulk hydrous explosive used for industrial blasting, such as crushed stone, mining, tunnel excavation, or a discharge device for an intermediate thereof.

国内の発破現場における爆薬の装填方法は、カートリッジ式の爆薬であれば作業者の手による手装填、流動性のある硝安油剤爆薬(以下、ANFO)であれば手装填かANFOローダーによる機械装填が行われてきた。
しかし、手作業では、発破孔に接近しなくてはならず、危険であることや装填に要する時間が長いこと、また、ANFOは、耐水性が劣る事、また、反応性が悪く、破砕効果も悪く、坑内発破の際は後ガスが問題になること等、多くの改善点が求められてきた。
The explosive loading method at the blast site in Japan is manual loading by an operator for cartridge-type explosives, and manual loading or loading by an ANFO loader for flowable ammonium nitrate explosive (ANFO). Has been done.
However, in manual work, it must approach the blasting hole, which is dangerous and requires a long time for loading. Also, ANFO has poor water resistance and poor reactivity, and has a crushing effect. However, many improvements have been sought, such as the problem of after-gassing during underground blasting.

それに対応すべく、最近では、爆薬製造工場で爆薬として製造されたプレミキシングバルクエマルション爆薬がいくつかの現場で使用されるようになり、流動性を有することから機械装填が行われ、装填時間の短縮化、省力化、安全化が進められようとしている。しかしながら、現在、プレミキシングバルクエマルション爆薬は軟質不定形容器にて運搬及び貯蔵される場合、現場で装填装置タンクに移し替える場合は手作業での移し替えが行われている。袋から高粘度である爆薬を手作業で排出するのは容易でなく、手が汚れ、袋に多くの残薬が残るなどの問題がある。特許文献1では、バルク含水爆薬またはその中間体が入った容器を可倒式の台に吊し、ヘラ及びまたは円柱状の棒で排出する方法が開示されているが、完全な手作業であるため労力を要し、排出量が作業者によって異なり、残量が多くなった場合、爆薬等のその後の処理に困るといった問題がある。また、特許文献2では、爆薬運搬容器である貯留槽と、その貯留槽から爆薬を取り出す取出装置と、貯留槽から取り出された爆薬を装薬するための装薬装置から構成される爆薬装填装置が開示されているが、爆薬運搬容器は繊維強化プラスチックなどの合成樹脂又はアルミニウムやステンレス鋼などの金属により形成された硬質の一定の形状を有する容器を用いており、記載されている取出装置では残薬が多く、爆薬が取り出された後の容器の移動や貯蔵における作業やスペースの問題、残薬処理などの問題がある。

本発明を実施例に基づいて説明する。
[実施例1]
軟質不定形容器(厚さ150ミクロン、幅260mm、ナイロン/接着性樹脂/ナイロン/接着性樹脂/低密度ポリエチレンの5層から成る平織りプラスチック製)に入ったバルク含水爆薬(硝酸モノメチルアミン28重量部、水10重量部、硝酸アンモニウム45重量部、硝酸ナトリウム8重量部、グアガム1重量部、カルボキシメチルセルロースナトリウム3重量部、シラスマイクロバルーン5重量部を50℃で混合したもの)10kgを図1に示す排出装置(ローラー直径;30mm、ローラー材質;芯材ステンレス、表面ウレタンゴム(厚さ5mm)、幅30cm)を用い、1MPaの圧力で軟質不定形容器を挟み、容器上端から排出口に向かい、ローラーを含む絞り出し部をゆっくりと手で降下させて、爆薬を受け容器に排出した。残薬量は排出後の袋の重量からバルクスラリー爆薬を入れる前の袋の重量を差し引くことにより求めた。圧力測定フィルム(プレスケール)は、富士フィルムビジネスサプライ(株)製プレスケール(商品名富士プレスケール)を用いた。
結果は、排出作業は極めて容易で手が汚れることは無かった。所要時間は運搬容器を投入装置に設置してから10秒であった。残薬量は0.8gであり、目視では確認できない程度まで排出することが出来た。
The present invention will be described based on examples.
[Example 1]
Bulk hydrous explosive (28 parts by weight of monomethylamine nitrate) in a soft amorphous container (thickness 150 microns, width 260mm, made of plain woven plastic consisting of 5 layers of nylon / adhesive resin / nylon / adhesive resin / low density polyethylene) 10 parts by weight of water, 45 parts by weight of ammonium nitrate, 8 parts by weight of sodium nitrate, 1 part by weight of guar gum, 3 parts by weight of sodium carboxymethylcellulose and 5 parts by weight of Shirasu microballoon at 50 ° C.) Using a device (roller diameter: 30 mm, roller material: core material stainless steel, surface urethane rubber (thickness 5 mm), width 30 cm), a soft amorphous container is sandwiched at a pressure of 1 MPa. The squeezed part containing it was slowly lowered by hand, explosive was received and discharged into the container The amount of the remaining drug was determined by subtracting the weight of the bag before the bulk slurry explosive was charged from the weight of the bag after discharging. As the pressure measurement film (prescale), a prescale (trade name Fuji Prescale) manufactured by Fuji Film Business Supply Co., Ltd. was used.
As a result, the discharging operation was extremely easy and the hands were not soiled. The required time was 10 seconds after the transport container was installed in the charging device. The amount of the remaining drug was 0.8 g, and could be discharged to the extent that it could not be confirmed visually.

[比較例1]
実施例と同じ軟質不定形容器に入った実施例と同じバルクスラリー爆薬10kgを、作業者1人で素手で実施例と同じ容器に排出した。残薬量は排出後の袋の重量からバルクスラリー爆薬を入れる前の袋の重量を差し引くことにより求めた。
結果は、バルクスラリー爆薬が高粘度であることから排出は極めて難しかった。バルクスラリー爆薬を手で絞り出そうとしたため手が汚れ、十分排出するには3分を要した。残薬量は250gであり、目視でもバルクスラリー爆薬の付着残薬を確認することが出来た。
実施例と比較例の結果から、本発明のバルク含水爆薬またはその中間体用の排出装置は、作業が容易で手が汚れること無く、残薬も少なく排出が行えることが分かる。
[Comparative Example 1]
10 kg of the same bulk slurry explosive as in the example contained in the same soft amorphous container as in the example was discharged into the same container as in the example by one operator with bare hands. The amount of the remaining drug was determined by subtracting the weight of the bag before the bulk slurry explosive was charged from the weight of the bag after discharging.
As a result, discharge was extremely difficult because the bulk slurry explosive had a high viscosity. It took 3 minutes to drain the bulk slurry explosives by hand because it was dirty. The amount of the remaining drug was 250 g, and the adhered residue of the bulk slurry explosive could be confirmed visually.
From the results of Examples and Comparative Examples, it can be seen that the discharge apparatus for bulk hydrous explosives or intermediates thereof according to the present invention is easy to work and does not get dirty from hands, and can discharge less residual drugs.

本発明のバルク含水爆薬等用の排出装置は、砕石、採掘、トンネル掘削などの産業発破の分野で好適に利用できる。   The discharge device for bulk hydrous explosives of the present invention can be suitably used in the field of industrial blasting such as crushed stone, mining, tunnel excavation and the like.
