Title:
PROCESS FOR DISPERSION AND POWDER CHARGING OF EXPLOSIVE
Document Type and Number:
Japanese Patent JP2018021744
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enable an explosive charging time when the explosive charge is loaded into a blast hole as found in a base rock or the like to be shortened, enable cost and construction period to be reduced by improving a work efficiency, and enable blast energy to be dispersed by easily dispersing and arranging the explosive at an arbitrary position of the blast hole and efficient blasting to be realized.SOLUTION: This invention provides a process for dispersing and loading explosive comprising the steps for: processing an explosive holding plate 1 including a plate member 11 made of long thin-plate-like paper or wooden material; holding several dynamites 2 spaced apart in a long direction X of the plate member 11 in regard to the plate member 11 to manufacture a loading explosive unit 10; and after loading the loading explosive unit 10 into the blast hole 3 punched at the base rock, pushing filling object thereinto to close a hole port 3a of the blast hole 3.SELECTED DRAWING: Figure 1
