摘要
针对棒磨山铁矿露天台阶炮孔涌水量大的实际情况 ,研究采用水耦合预烈爆破方法解决含水炮孔的边坡预裂爆破问题。根据炮孔含水高度的不同 ,进行了不同装药结构的水耦合预裂爆破现场试验。经爆破效果测试分析 。
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.
