Abstract:
The article addresses the problem of charging water-filled boreholes with cartridged emulsion explosives in conditions where the use of mixing-charging machines is impossible or economically impractical. The traditional manual charging method often leads to disruption of the charge column integrity, formation of water interlayers, and sticking of cartridges. To solve these problems, a new device for forming the charge column is proposed. The method allows controlled lowering of the cartridge into the borehole, avoiding water hammer during the transition from the air environment to the water environment, and prevents sticking and the formation of water interlayers. The developed technical solution is recommended for industrial application in open-pit mining operations under complex hydrogeological conditions. The article also outlines directions for further research: evaluating effectiveness in boreholes of other diameters, increasing the sample size, direct measurements of detonation velocity, and analysis of oversized fragment yield.
