摘要(Abstract)：

介绍了复杂条件下危岩体的爆破排险实例。树立先加固再排险的思想,设置冗余系统,有效地避免了滚石的危害;采取合理控制单耗、小药量松动爆破、层层剥离碎石,避免了飞石,减弱了地震波;并阐述了炮孔布置、单孔装药量等参数的确定以及安全防护措施,为此类工程积累了经验。
Danger elimination case of unstable rock mass by blasting was introduced in complex environment.Measures were taken to reinforce the unstable rock mass before eliminating the dangerous situation and security system was set to avoid the damage of rolling stone effectively.Strength of seismic wave was weaken obviously and flying rock was avoided by controlling unit explosives consumption reasonably,using loose blasting with small charge,and layer by layer stripping gravel.Blasting parameters such as holes layout and single hole charge as well as safety protection measures were described.All of which are available for similar projects in the future.
