集中药包在开挖路基高崖中的成功应用

对不具备修路条件，不适合大型凿岩设备进行常规开挖的露天高崖，通过底部开凿小型导洞和药室，合理选择最小抵抗线，布置集中小型药包，并严格控制破裂半径，预留边坡保护层，复式网络微差爆破顺利爆破岩崖，降低施工掌子面高度，为后续项目的开工修筑创造条件，节约了工期。

Major hazard sources analysis and prevention measures of packaging emulsion explosive production line

Emulsion explosive with favorable water-resistance performance,storage performance and detonation stability has been widely used in all over the world.The development actuality and production technique characteristics of emulsion explosive in China were introduced firstly.Taken the technique characteristics of packaging emulsion explosive into account,major hazard sources of emulsion explosive production line were analyzed.Finally,prevention measures based on inherent safety of emulsion explosive production were put forward.
