摘要
通过对大孤山铁矿现场取岩样,加工处理后,借助霍普金森压杆对岩石做动态冲击实验,得出岩石破碎所需的有效能耗,即用最少的炸药达到最优的爆破效果,减少爆破成本,以此指导爆破设计。
The rock samples are taken from Dagushan iron,the processed samples are conduct experiment based on Hopkinson compressive bar. The experimental results show that,the effective energy during the process of rock crushing is obtained. That is to say,reducing the blasting cost by using the least blasting explosives to achieve optimal blasting effect so as to provide guidance for blasting design.
