复杂环境下的路堑工程爆破

Engineering Blasting for Fault Trough in Complicated Envivonment

在复杂环境条件下进行路堑工程爆破 ,采用超钻预裂爆破、调整装药结构、选用低爆速低威力炸药、微差起爆控制单响药量等措施 ,有效降低爆破震动 ;采用土层覆盖、合理装药结构、增加堵塞长度等措施 。

An engineering blasting for fault trough in complicated environment was implemented. The measures such as the overdrilling pre-splitting blast, adjusting the charging structure, selecting the cool and low-strength explosive, and controlling the single dose by millisecond detonation were taken to effectively lower the blasting vibration. The measures such as coating with soil layer, using reasonable charge structure and increasing the stemming length were taken to effectively control the flyrock.
