摘要
本文对露天石灰岩矿台阶式中深孔爆破的爆破参数和爆破网路进行了优化设计,使用结果表明:爆破参数设计合理,矿岩爆破块度适中,根底现象基本消除,对露天台阶式中深孔爆破设计具有参考价值。
To standardize the production process of medium deep- hole blasting of terrace-type in open-pit limestone deposit, this paper takes open-pit limestone deposit as an example, designs the blasting parameters and blasting network. The results show that： the blasting parameters are reasonable, the blasting fragmentation of the ore rock is moderate, and the toe Rock has been basically eliminated. And this design has important reference value for the design of bench open-pit medium deep-hole blasting.
