露天采场

• In order to decrease the size of fragmentation and reduce blasting vibration effects on the stability of eastern open pit slope of tongshankou copper mine < this work involved two steps . first of all , based on the experiment in laboratory , this paper presented the optimum blasting parameters and applied it in practice
  为降低铜山口矿露天采场生产爆破的大块率和地震波振动强度，保证采场东帮陡边坡的稳定，本文在对国内外大量文献综合调研的基础上，首先采用正交设计对现场爆破参数进行了室内模型实验，得出优化的模型爆破参数后又应用于生产。
