摘　　要：降低露天爆破大块率几乎是所有露天爆破需要应对的问题。根据本工程实际情况,本文详细分析了现场爆破产生大块的原因,并提出降低中深孔爆破大块率的针对性措施。为了减少爆破大块现象,人们要根据环境因素,想法解决问题,在工程实践中不断学习,总结经验,持续改进,以求达到最优的爆破效果。Reducing the mass rate of open-air blasting is almost a problem that needs to be dealt with in open-air blasting.According to the actual situation of this project,this paper analyzes in detail the causes of large blocks gen⁃erated by on-site blasting,and proposes targeted measures to reduce the large block rate of medium-deep hole blast⁃ing.In order to reduce the phenomenon of large blasting,people must solve the problem based on environmental fac⁃tors and ideas,and keep learning in engineering practice,summing up experience and continuous improvement,in or⁃der to achieve the best blasting effect.
