Document Type and Number:
Japanese Patent JP2018021743
Kind Code:
A
Abstract:
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
