摘　　要：通过工程类比、数据分析、工程应用,集合水源保护区内、距离既有取水泵站中心控制室10~80m、40m深基坑灰岩质石方开挖等条件,研究石方分区域控制爆破开挖工艺,设计安全爆破参数及安全措施并应用,实现了爆破岩石松动、粒径较小,利于出渣。爆破振动小,飞石可控。最大提高工序作业,提高作业效率等预期效果。Through engineering analogy,data analysis,engineering application and combined with actual excavation conditions,this paper studied the excavation process of rock blasting by regional control,designed safety blasting parameters and safety measures and applied them.It realizes loose blasting rock,small particle size and facilitates slag production.The blasting vibration is small and the flying stone is controllable.It improves the expected effect of process operation and efficiency.
