| 摘 要： | 复杂环境下深孔爆破的爆破参数、岩石性质和爆破效果之间存在着一定的关系,通过对这一关系的研究,找到了控制非破碎岩石的能量和改善台阶坡面质量以减少爆破危害性的途径,从而可确定兼顾爆破安全和破碎效果的台阶深孔爆破设计参数的选取范围。

| Abstract: | Practice of longhole blasting under complicated circumstances shows that there exists the relation of blasting parameters and roek properties with blasting fragmentation. Study indicates that the blasting damage can be minimized by controlling non-explosion energy and improving bench slopes. Selection range of design parameters for bench longhole blasting was proposed with both safety and fragmentation effect taken into consideration |
