摘　　要：为降低工程施工成本,提高市场竞争力,通过理论分析、设计并进行多组正交试验,对露天深孔爆破孔网参数进行优化,控制爆破单耗的同时降低了岩石大块率,从而控制了施工成本。对类似工程具有一定参考性。In order to reduce the construction cost and improve the market competitiveness,through theoretical analysis,design and multi-group orthogonal tests,the parameters of the hole network of open-pit deep-hole blasting were optimized,and the rock bulk rate was reduced while the blasting cost was controlled.It has certain reference to the similar project.

关 键 词：爆破 单耗 孔网参数
