摘要(Abstract):

在焦晋高速公路K5 + 840~K6+ 0 10段的石方开挖中 ,采用了条形药包硐室爆破。为防止爆破震动危及周围建筑设施和影响边坡稳定 ,必须控制单响药量。文中介绍了起爆网路设计的基本要求和网路的选择 ;论述了非电微差接力网路的设计、施工工艺。同时介绍了 2个台阶条形药包硐室爆破起爆网路设计与施工的实例。
In rock excavation of K5+840~K6+010 section for the Jiaojing Express Highway,the chamber blasting with linear charges was used In order to protect the surroundings and slope stability against the effect of blasting vibration,the maximum charge weight of delay interval must be under control In this paper,the basic demands for the design and selection of an initiation network were introduced,and the design and implement of non electric millisecond relay initiation network were discussed At the same time,two practical examples of bench chamber blasting with linear charges about the design and implement of initiation network were presented
