Four aspects,namely,the system of developing,effects of wide space blasting,shape of blasting area and single-hole charge,which should be paid attention to in the design of open medium-depth hole bench cut blasting,are put forward in this paper.
根据作者的实际工作经验,提出了露天台阶深孔爆破设计中应注意的4个问题:1)开拓系统建设关系到土石方工程的布局,影响工程成本和进度,应予以足够重视;2)采用正三角形布孔,斜线起爆,即可取得小抵抗线宽孔距的爆破效果;3)爆区形状以长方形或平行四边形为好,长宽比应大于3;4)单孔药量计算应综合考虑爆破参数之间的逻辑关系。
