EXPLOSIVE HOLDING PLATE, LOADING EXPLOSIVE UNIT, AND PROCESS OF MANUFACTURE OF LOADING EXPLOSIVE UNIT

PROBLEM TO BE SOLVED: To enable an explosive loading time when an explosive is loaded in a blast hole at a base rock and the like to be shortened, enable work efficiency to be improved, enable both cost and construction period to be reduced and further enable an explosive to be easily arranged at an arbitrary position of the blast hole.SOLUTION: This invention provides an explosive holding plate that is constituted in such a way that there are provided a long thin-plate-like plate member 11 made of paper or wooden material that can be folded and an adhesive agent 12 provided at a fixing surface 11a at one surface of the plate member 11 so as to fix dynamite 2 inserted into a blast hole 3 punched at the base rock, the plate member 11 is formed into such a shape as one that can be inserted into the blast hole 3 under a state in which the dynamite 2 is fixed through the adhesive agent 12, a parallel folding line 11b is formed in a long direction X of the plate member 11, an inner corner side of the plate member 11 folded and bent along the folding line 11b is formed with a storing recess 11c where the dynamite 2 is stored and the adhesive agent 12 is provided at the storing recess 11c.SELECTED DRAWING: Figure 1 【課題】岩盤などの発破孔に装薬する際の装薬時間を短縮することができ、作業効率を向上させることができ、工費及び工期の低減を図ることができ、さらに発破孔の任意の位置に爆薬を容易に配置することができる。【解決手段】長尺薄板状の紙材又は木材からなる折り曲げ可能なプレート部材１１と、プレート部材１１の一方の面の固着面１１ａに設けられ、岩盤に穿孔された発破孔３に挿入されるダイナマイト２を固着させるための接着剤１２とを備え、プレート部材１１は、接着剤１２を介してダイナマイト２を固着させた状態で、発破孔３に挿入可能な形状に形成されるとともに、プレート部材１１の長尺方向Ｘに平行な折り目部１１ｂが形成され、折り目部１１ｂに沿って折り曲げたプレート部材１１の内角側には、ダイナマイト２が収容される収容凹部１１ｃが形成され、収容凹部１１ｃに接着剤１２が設けられた構成の爆薬保持プレートを提供する。【選択図】図１
