路堑开挖中深孔爆破优化处理

摘要

To enhance blasting effect, this paper analyzes the problems of one road excavation project of Zhengan city, and uses some methods to im-proving the middle- deep hole blasting technique including deck charge and hole- by- hole blasting, and has successful y reduced the big rock ratio and blasting vibration,gotasuitabl erockloosedegree,and improved blasting effect and blasting safety.%为了提高爆破破碎效果，对正安城市主干道翁家坡段路基施工中存在的问题进行了分析，采取措施对中深孔爆破工艺技术进行了优化，选取了间隔装药、逐孔起爆等手段，成功降低了大块率，减小了爆破震动，爆后达到合理的集中度和松散度，提高了爆破质量和爆破作业的安全性。
