| Abstract: | Based on the excessive seepage water in the blasthole of the open mine's step of Bangmoshan, it is studied that using water coupling presplitting blasting to resolve the problem of slope presplitting blasting with water bearing blasthole. According to different water altitude in blasthole, different presplitting blasting experiment of water coupling of different charging construction have been carried out in site. After testing and analyzing the blasting effect, it is summarized that using this technology is available to solve presplitting blasting of side slope in water bearing blasthole. |
| Keywords: | presplitting blasting water bearing blasthole water coupling absorbing shock rate |
