摘要
在分析露天台阶爆破时台阶坡面岩石爆破特点的基础上 ,提出了台阶爆破前排抵抗线长度计算模型 ,从而推导出计算合理前排抵抗线长度的近似公式 ,可供爆破设计时参考。
On the basis of analyzing the blasting characteristics of rock at bench slope in open-air blasting,this paper puts forward a calculation model of front-row burden,and deduces an approximate formula for calculation of reasonable front-row burden length for open-bench blasting,which can be used as reference for blasting design.
