摘要(Abstract)：

综合介绍了水利水电地下工程洞室群开挖爆破技术取得的成就和发展水平 ,阐述了地下厂房洞室群的开挖方法和施工程序。厂房洞室采用分层开挖方式 ,与厂房洞室相邻的洞室 ,采用浅孔爆破。对于斜井 ,其施工方法是先挖导井 ,再自上而下扩挖 ,导井多采用爬罐法开挖。文中还介绍了光面爆破、预裂爆破在厂房洞室、吊车梁岩台、竖井以及交叉洞室开挖中的应用
The achievement and progress of blasting techniques for excavation of large underground tunnels and chambers were introduced and the constructing mode and sequence for excavation of underground powerhouse and relative chambers expounded The slice excavating method was used for excavation of underground powerhouse and the tunnels and chambers close to the powerhouse were excavated by use of short hole blasting The method of excavating an inclined shaft was that a pilot incline was formed,followed by slashing from top to bottom And the pilot incline was excavated by the climber method Also,application of smooth and presplit blasts in excavation of powerhouses,crane girder rock support,shafts and crossing tunnels was presented
