摘要
根底率是评价露天矿山爆破效果的重要指标之一。根底既影响当次爆破的铲运作业,也影响下一台阶爆破的钻孔质量。详细分析了露天台阶爆破根底产生的原因和位置,并有针对性地提出了解决措施。本文的研究对提高爆破质量、有效降低根底现象具有一定的参考价值。
Bedrock rate is one of tbe important indexes to evalu ate the effect of blasting in open-pit mines. The bedrock not only affect s the shoveling and transportation operations for the time of blasting but also drilling quality for the next bench blasting. The paper analyzes reasons of the open-pit bench blasting bedrock production and its position and put forward measures for its solu- tion. Exploration conducted in the paper provides a reference for improving blasting quality and effectively reducing occurrence of the bedrock.
