摘要
本文通过试验对扇形中深孔爆破参数的优化进行了研究,从装药结构、最小抵抗线、起爆顺序等参数对扇形中深孔爆破效果进行了理论分析和现场试验,得出合理间隔装药,小抵抗线、大孔距,导爆索辅助起爆等措施对扇形中深孔爆破效果的改善有直接关系。
In this paper,the optimization of the parameters of fan-shaped medium and deep hole blasting is studied through experiments.The theoretical analysis and field tests are carried out on the blasting effect of fan-shaped medium and deep hole from the parameters of charging structure,minimum resistance line,initiation sequence,etc.it is concluded that the measures of reasonable interval charging,small resistance line,large hole distance,and detonating assisted by detonating cord are directly related to the improvement of the blasting effect of fan-shaped medium and deep hole.
